9999 UNKNOWN UNKNOWN with 64800.0 miles

Nissan dealership service diagnosed air flow meter failure - engine light on P0171 b1 fuel lean. Event happened at same time as when the crank sensor and ecm case recall work done except dealership claims separate - not part of covered recall work. Auto only has 64,889 miles and dealership claims engine trouble and repair over $600. Nissan dealership stated toyota slaes dealership should have noticed this during claimed 160 point inspection, as could not have happended in short time of my ownership. Toyota dealership who sold it also did not repair or disclose wheel recall and owner, in just one year of ownership, had to replace three flat/damaged and irrepairable tires as a result, out-of-pocket. Now for nissan to diagnose engine air flow meter failure at same time as other engine recalls is just too ironic timing. Believe should be part of these same related or another recall.*ak

2018 TOYOTA CAMRY

Check engine light came on and the performance of the vehicle is bad. Bad idle, weak engine, just the car is not performing properly. I used the scanner to see the code and i had more than one . P0171 P0505 P117B P0441 P0455 . Fuel/air mixture is lean . And i hear the fuel pump making that noise that indicates a bad fuel pump. It's when i put the key in i hear it loud enough and if i turn the key on it does it again. When i put it on p it revs and rpm goes up and then comes down, up again down again ... When stopped at a red light the car wants to move and rpm keeps shaking.

2015 TOYOTA RAV4 with 50493 miles

Ongoing issues with my fuel system. Car will display one of these many symptoms: -misfire, hard start, stall or shutoff. Other symptoms include car stuttering and stalling out while driving. This last symptom is very dangerous as it often comes with no warning. When the car stalls out, the car is driving up straight up a medium grade hill. I have experienced this on several different dates and times along w 24th st. Austin, tx near 1106 w 24th st. This will happen if i'm either stopping at a light or while in motion. I don't have the exact mph i am driving, but it would be around 20 - 40 mph when this occurs. Ive taken the care to both round rock Toyota and christian auto brothers to address the issue. So far, neither have been able to diagnose the problem. On 5/22/20, christian auto brothers replaced the evaporative emissions system leak detection unit r&r, the fuel evaporative canister r&r, the evaporative emissions system leak detection pump, and the vapor canister purge solenoid. This did not resolve the issue. Current codes: P0441, P0455, P1604, P1605, P0171. While no diagnostic proof has been established, it is hypothesized by the mechanics that there is an issue with either the fuel pump or the fuel line. After reading about the 2020 Toyota fuel pump recall, i believe my 2015 Rav4 has been experiencing similar issues. However, it is not part of the recall. Therefore i am submitting this incident info to document the current situation. If i learn more, i will try to update.

2014 JEEP COMPASS with 67785.0 miles

On march 4, while vehicle was in warm-up phase at home, in idle, a sharp snap was heard (later discovered was the electronic throttle body), then vehicle set two codes (P0171, P2173), and immediately went into limp mode (traction control off, throttle body reduced power, abs for slowing vehicle if being driven above slower speeds for limp mode). We were on a schedule, so vehicle was shut off immediately and we used our other vehicle for transport. Both codes were researched to determine best repair methods. Since the P0171 was a repeat code, and the P2173 was an unfamiliar sae code not normally used on my previous vehicles, a complete disassembly of the intake was warranted. I am mechanically competent due to training and experience and know my own limits of competency and tools for repair. Here are the basics for reference of what was found. 1. The pcv valve (multiaire) had failed at the internal pintle, and was allowing crankcase air/oil to enter the intake at too high a volume. It was replaced. The map sensor set the P2173 code, then failed due to oil intrusion and was replaced. The rapid snapping of the throttle body under pressure uncalibrated the internal throttle position sensors, and could not maintain proper position was replaced. The intake manifold (newer design for the 2.0l i4 without the flapper controls just guide veins for the intake air) main gasket had shrunk in the plastic intake seat channel and was allowing outside air (P0171) to seep past the gasket on the lower lip of the gasket, and was also not sealing between the cylinders (gases were transferring between the cylinders). The throttle body gasket was pristine. During repair, pressure tested intake for leaks, and tubes and lines for cracks. Reading sae code P2173 was determined that code and subsequent limp mode was designed to prevent damage to the plastic intake manifold. It worked.

2014 CHEVROLET SONIC with 62000.0 miles

On 03/12/2018 my check engine light came on while driving on the access road, while at a stop light my car started "buckling", when light turned green hesistation and major loss of power occured. Finally got going and when i got back to work and park it wouldn't start after i went in and came back out. Got it jumped and went to both napa and auto zone both said it was mass airflow sensor. Got the part the from the dealership and replaced it. All was well till today 03/15/2018 check engine light comes back on and my car started hesistating on the highway and eventually stalling as i was pulling of to the access roads. Prior to hot air was blowing out of my a.C while the cold setting was on. Made my way to auto zone and they said it was P0171 running to lean/too much air. In the parking lot ensured the oil cap, dip stick, air filter cabin were all sealed tight, wires were fine, upon inspection of the air cleaner intake duct hose found out it was broken all the way around the hose. Called my extended warranty agent and he informed me that it is a common problem with this vehicle and that it may not be covered. If the extended warranty people and the manufactures know of this, why not mention it in the manual or have the techs who change our oil and air filters look at it and mention it to us since its right next to the air compartment. As i drove it back home to park, the engine stalled on me again luckily it was as i was parking.

2014 RAM 1500 with 1895.0 miles

While driving at a speed of approximately 25 to 30 mph, the engine stalled. This happened three times in the same day. It continues to happen at random up until the present usually when coasting or turning. The check engine light came on at 2,307 miles and codes P0171 and P0174 were found and both oxygen sensors were replaced. Three days after repair truck continues to stall. Has been in for service five times and no other repairs made because they say they can't duplicate the problem and the check engine light has not come on again. Invoice shows that there is a stored code, P0884, but since it is not active they will not be authorized or paid to repair the truck. The description of this stored code is exactly what i have been complaining that the truck does, stalls when turning or coasting at a speed of 20-30 mph. I guess money is more important than customer safety.

2013 SUBARU BRZ with 93000.0 miles

In late 2018 i was notified by Subaru of the valve spring recall for my 2013 Brz. I carried my car in on march 31st 2020 to have the recall done. I picked my car up on april 9th 2020. On april 14th 2020, after exiting the highway, my engine stalled at a red light. It restarted on the first try with check engine light and traction light on. I drove the car directly back to the dealer to check that everything was done correctly. The diagnosis was fault P0017 and throttle body carbon up. The technician performed an ecm update and cleaned the throttle body and returned the car to me. No charges were incurred. On may 12th 2020 while driving, the check engine light and traction light came on once again. I again brought the car back into the dealer to be checked out. The diagnosis was fault P0171 system too lean. Checked for leaks and found none. The mass air flow sensor was cleaned and the car returned to me. No charges were incurred as it was admitted that debris could have gotten in the sensor while the engine was open performing the recall. On june 4th 2020 , after exiting the highway, the engine stalled again. This time 5 tries to restart the engine were to no avail. On the 6th try the engine finally restarted with no warning lights on. I drove the car back to the dealer. My car was kept for 1 week and the diagnosis was a bad mass air flow sensor. I was charged $651.44 to replace the sensor. My car was returned to me on june 12th 2020. On june 13th 2020 the check engine light and traction light was back on. When i carried my car in on march 31st 2020, there were no prior issues with the engine or any other component on the vehicle. The car drove and functioned perfectly fine. There have many complaints about the Brz recall making engines. I believe i've fell victim to this. Please investigate the Subaru/toyota valve spring recall for 2013 Brz and frs.

2013 CHEVROLET SONIC with 80000.0 miles

My 2013 chevy Sonic developed ticking sound shortly after i bought it at 60000 miles. The ticking got worse over time and then check engine light came on. I scanned the codes and multiple four codes were found. P0171, P0496, P1101, and P2270. After doing some research it seemed to be that most cruze, Sonic, and trax vehicles all had the same issues. I took it to the dealer for diagnostics and was informed the vehicle needed a new intake manifold, purge valve, pcv hose, and valve cover. They called the dealership to see if there were any recalls and the only one was the valve cover but would have to pay for diagnostics to see if they would cover it or not. The breather diaphragm in the valve cover goes bad due to a fault intake manifold on these vehicle models. There is a little orange gasket in the manifold that goes bad and causes the diaphragm to go out resulting in having to replace the entire system. The intake manifold not only causes ghat issue but causes the car to get jumpy at stops and stalling out. Have almost had a few people rear end me due to this. The purge valve goes out as well and when at the fuel pump the car will hesitate to crank or run at very low idle shutting off multiple times before it starts up and then runs rough until a decent amount of fuel has ran through the engine. The car would not get enough fuel when at stops or on highways and would also just lose fuel and cut the engine off. Those components have since been replaced by myself and no more issues. Chevy will not recall the parts that are causing the issues and therefore there is a safety issue when out on the highways.

2013 CHEVROLET SONIC with 200000. miles

Gm part number 95027313 outlet duct connecting the air box to the throttle body has shredded in 30,000 miles of use. This problem causes the engine to run lean (odb2 error code P0171) resulting in significantly reduced fuel economy, poor acceleration, rough idle, and potential failures to a number of costly sensors and components, as well as allowing dirty, un-filtered directly into the engine. A quick google search reveals 26,000 search results including forums and message boards where countless Sonic owners report the same issue. This is a widespread product defect and gm needs to provide a repair solution for owners of this model vehicle. The part had deteriorated to the point, where the check engine light illuminated. The consumer noticed the fuel economy of the vehicle dropping steadily from the advertised 29/city/40 highway to an average of about 25 mpg highway.

2012 SUBARU OUTBACK with 39120.0 miles

On may 15th, while driving on a city street, dashboard warning lights came on indicating "brake" and "check engine". Took it to a Subaru dealer in berlin ct who found the following: "trouble code P0171/system to lean bank 1, fault traced and found vacuum leak around brake booster check valve. Vacuum valve cracked. Recommend replacing brake booster assembly". This vehicle has only 39,120 miles. This part is well protected within the engine area. Service repair described the part as a small plastic piece and stated he's never seen this happen before. To my way of thinking, the part had to be defective when the engine was built. Car was never in an accident and has always been maintained by Subaru dealers. Cost is a little over $700.00. I have the work order if you need it; but the wording above is directly from the order. Is there a way to start an investigation showing this is a manufacturers fault? Is there any way i can force Subaru to pay for this?

2009 VOLKSWAGEN PASSAT with 108000. miles

On 1 september 2017, i parked my vw in my garage. There were no engine lights on or anything, but the car had been making a loud fan like noise after i removed the key fob from the ignition. Its been doing that since i bought it. I didn't start the car back up until 5 september 2017 after returning from a weekend with family. When i started my vw up i noticed that the engine light was now illuminated. I waited about a week before i took any action hoping that the light would just go away on its own, but it didn't. On 12 september i took the car to the nearest autozone and took advantage of their free engine light diagnostic check. The error codes read "P0171 system too lean (bank 1)" and "P12A2 fuel rail pressure sensor inappropriately high." at the top of the paper it stated that the most likely solution for these error codes was to replace the fuel pump. Once i returned home i called the local Volkswagen dealership and told them what the problem was, they told me that there was a recall out for my model vehicle, but there is no fix at the moment. I then went online to see for myself, the manufacturer recall number is: 20ae and the nhtsa manufacturer number is: 17v509. I am not sure what caused the vehicle to randomly start having these issues. I do not feel safe driving the car out of town anymore, i only drive it to and from work.

Me my family had taken a vacation to florida and the transmission began to startle all the way back to tennessee leaving us in a devastated situation . I was hoping there was a recall on the transmission and and air bags this is very dangerous as many others has complained about the same issues in the past concerning their 2008 Acadia vehicles this vehicle was in motion on a city expressway with a high volume of fast moving traffic. I went to auto zone and o' reilly auto parts to have check engine test and the following codes appeared dtc P2762 torque converter clutch,P0700 automatic transmission control,P0171 fuel control system. And computer error.

This car is a mess. It didn't pass the state emission test sticker. The traction control system in conjunction with the stability track control system.

I don't know what the problem is and two gmc Buick dealer have said different fix method. Very back for me. They want to fix different problems. They don't know what the real problem is. They are guessing.

The soft codes said P0171, p 0174, p 0420, p 0300 is crazy.

2008 AUDI A3 with 154000. miles

The check engine light illuminated and has not been able to properly diagnose. More than one mechanic has told me the code P0171 that reads as the diagnostic does not correlate with my car as my car does not have a pcv valve. They have inspected the car to look for similar issues and have found none. Yet the check engine light remains illuminated. There was a recall reported 09/30/2009 on my type of car under campaign 09v377000 but my vin is not showing as affected by that campaign even though the code that is coming up is a similar issue. I am extremely concerned about the safety of driving my car now. I can't not repair what i can not diagnose. I believe that i am affected by the recall.

2008 SUBARU WRX with 121475. miles

For the last month or so i had smelled gas fumes periodically when the my car was idling. A few days ago the car went into limp mode. I had the ecu code read at a local store and the technician there stated that the engine code was "P0171 system too lean (bank 1)". On monday i took the car to the local dealer. Their diagnosis was that the fuel line was deteriorating and needed replacement. They also indicated that the fuel line was leaking. Their explanation for the engine code was that while the car was running the fuel pressure expanded the fuel line. This expansion eventually reduced the fuel pressure to the point that the fuel injectors were not receiving adequate fuel and the ecu threw a code. While i do not know why the fuel line degraded, and there could be a number of causes, it does seem premature.

2007 ACURA TL with 34000.0 miles

Since i purchased my vehicle i have been back and forth to the dealer at least a half dozen times for the "tighten fuel cap" light. Each time i was told nothing was wrong. I switched dealerships and they finally replaced the fuel cap, neck and another part that i cannot recall now. That fixed the problem for a short time, now i have another diagnostic code, 2 actually, P0171 and P0174. The message center for the fuel cap and these codes all said it is related to my emission system. I see one other person filed a complaint on here relative to the gas cap light coming on. I am coming close to the end of my warranty and asked Acura to extend it but was told to call back when it closer to expiring. This is not boosting my confidence right now.

The first indication was the crl came on with codes P0171 and then P0174. When pressing the brake pedal down, there is a hissing noise and the brake pedal would basically go all the way to the floor. It sounds as if this has happened quite a bit with this model and should be looked into. The dealer has told me that the brake booster must be replaced and that the vehicle is not safe to drive at this point.

2007 TOYOTA CAMRY with 89389.0 miles

We where driving to the store and on the way the check engine came on, so we pulled into the local autozone and they ran a scan for fault codes. It had a code P0171 which they said it coulf 1 of several posibilities and should have a repair shop perform a proper check to be sure what is actually going on. Well we continued on to the store, when coming to a stop my wife said we have no brakes, the pedal was going to the floor, we did come to a stop with hitting anything thank god. Well i drove from there back home very carefully. Once home i look under the hood for anything that be causing it to happen, and everything look inplace and ok. So next i got back into the car and push the brake pedal down and heard a loud air leaking from the brake pedal, i got down by the pedal and push on the the pedal with my hand and could hear air coming out the boot. I called a mechanic and explained to him what was happening and he said it is my power brake booster. Next i got on line and found that alot of 2007 Camry's with anywhere from 40,000 miles up to and over 200,000 that have the power brake booster failing, and when i tried to fine one for my car i found that there are none anywhere, even at the dealership. I did ask if they know of this problem and he paused for a moment, then said no. I believe this should be investigated be fore someone injured or killed.

2007 TOYOTA RAV4 with 73700.0 miles

First noticed the problem on 11/10/2014 when approaching a stop light. The Rav4 took longer than normal to come to a stop with greater force required to stop. Once fully stopped, the vehicle was idling with low rpm's (~500) and the check engine light turned on along with vsc and trac lights. Was able to drive the vehicle home, but experienced the same symptoms at every stop light / stop sign. Contacted Toyota dealership in tucson immediately and scheduled emergency service for the next morning. The Toyota dealership diagnosed the problem with two error codes (P0171 and P0174 - lean air/fuel mix). Was told they suspected a bad tank of gas. Toyota addressed one open recall (service campaign bst - reflash brake control computer) on my vehicle but did not investigate the error codes, only cleared them. The following day while driving home, the same issue occurred. Almost no brake pressure and barely able to stop. Check engine light, vsc, and trac lights all illuminated again. Low idle speed as well. Contacted a different local mechanic for a second opinion. Was informed the brake booster needed to be replaced due to damage in the diaphragm causing loss of vacuum pressure (which helped explain the two error codes related to lean air/fuel mix). Total repair bill over $1000. Just lucky nobody was injured due to failing brake system on Toyota's part.

2006 MERCEDES BENZ C55 with 130000. miles

Very strong fuel odor inside cabin of vehicle while driving. Odor is very strong around drivers rear wheel and from the outside once parked. Also noticed gasoline/fuel accumulation underneath vehicle around driver's side rear, on under body panels. Smell of fuel is very strong at times while driving but seems to dissipate when driving at a faster speed i.E. On highway over 45mph. Once i come to a stop or drive below 45mph the smell is pronounced probably because it isn't being blown away from the vehicle while driving. Does not change in correlation to fuel tank fill level. Inspected fuel sender under access cap, underneath rear passenger bench driver's side on august 27th 2016. Found fuel puddling in/around the exterior of fuel sending unit. Fuel sending part number a209-470-04-94 cleaned out fuel puddle and reinspected access to panel to fuel sender on september 3rd and found the fuel sender area has puddled with gasoline again. Check engine light periodically turns on with code P0171 usually a month in between dating back to 2015. Coinciding with the fuel smell. Inspected gas cap/filler tube for leaks as precaution but found no leak. Most of these symptoms are also similar to case with the 2003-2006 Mercedes Benz e55 amg vehicles found under nhtsa action number: ea13003 regarding emissions recall for amg models using high pressure fuel systems.

2006 FORD RANGER with 69440.0 miles

Vehicle stalled in middle of an intersection at 46,00 miles and was found to have lean codes P0171 and P0174-they replaced the intertia switch. Vehicle went in for service and a po306 cylinder misfire, but paperwork stated could not duplicate. After repair, vehicle kept giving me the check engine light if i filled the tank up with gas, but would clear itself before i would get to the dealer. One day i am makeing a left hand turn and the check engine light had come on about 5 minutes before. The Ford Ranger sputters across the intersection and then speed up very fast. Ii was lucky not to get smashed,as the light changed while my vehicle was sputtering. I immediatly took my truck to my trusted auto technician (not a Ford dealership)who told me i had po codes po304 and po316.The tech provided me with tsb number: 05-26-3 date of issue 12/31/05-(they knew my vehicle would fail before i purchased it!) the tsb states 3.0l-2v vulcan engine. Mil on various misfire related dtc's P0300 - po306 and P0316 issue 12/31/05 my 2006 Ranger with 69,000 mi displays all for the issues indicated on this tsb. This malfunction causes the mil lamp to continually display trouble codes P0302 and P0316. Because of this, my vehicle will not pass the ca state emissions inspection. The tsb states that if diagnostic tests indicate an engine exhaust valve seat recession, the cylinder heads will need to be replaced with the new service heads and is to be covered under emission warranty. I took the vehicle to the Ford dealership. Pacfic Ford redid the diagnosis and stated the issue was outlined in the tsb. They also stated that the parts were not covered by either the new vehicle or emissions warranty coverage. I called the Ford crc and was told there was nothing they could do to assist with payment to correct their defective part. The failure is not being corrected at this time.

2006 CHEVROLET EQUINOX with 57646.0 miles

Vehicle will not pass state required emission, due to readiness error code. For reasons unknown the evap and egr system code will not reset (not ready code). We were told by several mechanics to drive the vehicle for several hundred miles. After 800 miles and several failed test later the system still will not reset. We called gm and was told to take the car to a dealer. Against our better judgment we had no other options available and finally took it to our local gm dealer and was told the service tech downloaded software to address a P0171 code, which cost us over $300 and to drive it 200 more miles, bring it back for a test. The system still did not reset and the car will not pass emissions. We asked the service manager for other options and all he could give us was lip service (useless rambling), possible troubleshooting repairs and more money. I found on a topix website that gm recalled the pcm for the Equinox but could not find the recall on the nhtsa website. Please research and post the recall if gm has issued one for the pcm.

2006 CHEVROLET TRAILBLAZER with 58579.0 miles

2006 Trailblazer 4wd. The driver's side window become erratic during operation at first. Then entire electrical system was affected over next day or two, including making door locks operate on their own, heard electrical crackling sounds in door and dashboard. Smelled electrical fire fumes slightly once. Engine warning light came on, followed by light warning that stabilatrak had issues. Took it into Chevrolet dealership (harbor, 9911 w 300 n, michigan city, in. Phone (219) 210-4266.) after the service department investigated, they reported that the issue was a burned out drivers door module that had obvious charring on it. The service tech noted on invoice sheet that he found the engine light was indicating a P0171 diagnostic issue which he traced to the "failed/shorted" driver door module. The solution was to replace the module and program the new module. The next day after getting back the vehicle, the engine warning light came on again. A check by me using my obd unit shows that once again the P0107 is the issue. I have also again heard crackling in the door, but no electrical issues seen thus far. Will be heading back to dealership first chance that i get. Cost of the unit replacement was $524.62.

2006 CHEVROLET EQUINOX with 55502.0 miles

I took the vehicle to the shop to get it checked on 11-21-11. We took the vehicle thinking that a piston was bad, because that was the way it felt, like not getting the right pressure from the piston once the brakes were activated/pressed. Once we got the call back from mechanic, he stated that we needed new rotors due to both being warped. I thought that that will take the problem away but once we got the truck back, immediately within days the problem came back. We took the vehicle back to the shop and they stated it was a tire the one causing the noise and rattle once the brakes were pressed. At the shop, they replaced the front brake pads as well as the disc brake rotors, they applied lug nut torque 100, inflation 35/35, cleaned and adjusted rear brakes. After all of this was done, i still get engine lights on the dash board. I took the truck to get it tested at autozone for free and got this code on their machine oem number to cross: P0171 definition: fuel trim bank one condition explanation: the power train control module uses the oxygen sensor to calculate the air/fuel ratio of the engine. The computer has recognized a rich or lean condition on one bank only. Probable cause: a1. If bank one and two set together suspect fuel pressure or maf (mass air flow) sensor a2. Oxygen sensor defective. A3. Ignition misfire-repair. A4. Fuel injector problem. I have not used my truck for the past 2 and a half months for fear of having an accident if breaks fail to do their job or lock up while braking. It is stressful enough if computers/mechanics nor dealers make up their mind about what the codes are or mean. I also notice the the button for the all wheel drive does not work anymore and that is being in that stage since the problem started. If anyone has a solution to this issue, please let me know. Thank you.
