2012 FORD FUSION with 65000.0 miles

While sitting still or driving the steering will make an audible "clunk" you can hear and feel when turning left or right from the centered position. No code present upon first trip to dealer who recommended rack and pinion replacement. They "updated" the software per the recall specs. Service advancetrac warning came on about a week later and dealer said code C1278 appeared and recommended rack and pinion replacement. Seems like this should fall under the recall of the rack and pinion, but the service dept said it doesn't.

2012 FORD FUSION with 148000. miles

While turning onto a highway my car began to lurch. I pulled over and had assumed there was an issue with my brakes. As a precaution, i had the car towed back to my home. I then took the car to an auto shop to have the breaks inspected. The technician told me that the breaks were fine but that he had found the following codes: C1963, C1963-eo, and C1278-20. I discovered that there was a recall for steering related issues with 2012 Ford Fusions. While at a Ford dealership i was told my car did not apply to the recall and was quoted $3,800 for the repair. I was told the car was not safe to drive and that the wheel could come off without notice.

2011 FORD F-150 with 70000.0 miles

While driving and under no particular common conditions, the dashboard, instrument gauges, interior lighting, headlights, navigation panel suddenly begin flashing and blacking out. Then after a few seconds, come back to normal, but typically with a "traction control service" message on with the trouble light remaining on. This happens about every 10 minutes of driving. Once in a while, it lasted longer and clunking noises seemed to come from the drive train. However, a few occurrences were while turning and the power steering was out. I took it to a belle tire nearby and they could not fix the problem, saying the dealer had to update the abs module and gave me a printout of tsb 12-11-18 [attached scan]. They circled diagnostic trouble codes C1278 and C1963 as the ones that popped up in their analysis. I find no recalls of this item, but the steering issue is certainly dangerous.

2001 TOYOTA SEQUOIA with 100000. miles

Started with both vsc and trac lights on. In both warm and colder temperatures, the car abs engages. Feels like driving over gravel. Car pulls to one side or another, and braking seems almost impossible. This became more and more common. It started once every couple of months, to almost every trip. Toyota read codes and stated that it was yaw rate sensor that needed to be replaced. Over a cost of $1800. We changes it and the car acted normally for 1 day. A day later the lights came back on and the skidding occurred again. Even after replacing the yaw rate sensor and performing a 0-point calibration, they read the codes, and showed the following: C0371 yaw rate sensor output signal malfunction C1208 steering position sensor output signal malfunction C1234 malfunction in yaw rate sensor C1271 low output voltage of right front speed sensor C1272 low output voltage of left front speed sensor C1273 low output voltage of right rear speed sensor C1274 low output voltage of left rear speed sensor C1275 abnormal change in output voltage of right front speed sensor C1276 abnormal change in output voltage of left front speed sensor C1277 abnormal change in output voltage of right rear speed sensor C1278 abnormal change in output voltage of left rear speed sensor C1279 deceleration sensor is faulty C1281 master cylinder pressure sensor output signal is faulty they estimated that the cost of repairing all of these sensors was approx $4500. The likelihood that all of these sensors gave out at the same time, to me is highly unlikely. There has been numerous complaints about this car's braking system and this seems to be an exploit of yet another shortcoming of this car. Currently if the car sits idling for more than 10 mins, the vsc and trac lights come on regardless of temperature outside.

2001 TOYOTA HIGHLANDER with 101531. miles

I am experiencing problems with my 2001 Toyota Highlander. Whenever i press on the brake it pulsates,vibrates and it makes a distracting loud ratcheting sound. When the speedometer drops to less than 10mph- it happens. This happens so frequently, that i really hate driving anywhere. I took it to several different mechanics. After being told the problem that i am having is due to warped rotors and warn brake pads- i paid to have new brake pads and rotors installed. That didn't work. (now they say it is an abs problem) i took the Highlander to a Toyota dealer who without properly performing a computer scan, blamed the mechanics who replaced my rotors and brake pads for the problem that i have been having-and they told me that it was not the abs system. Anyway, i am still having the same problem that both professional mechanics disagree on. Pulsation, vibration and loud noises. Note: neither of the two indicator lights brake/abs has activated since the problem started. Finally, i took the Highlander to a third mechanic, paid for an inspection of my abs system and received several computer scan abs faults codes:C1271-C1278- abs activates at a lower speed. Also, master cylinder pressure sensor malfunction C1281. I want Toyota to repair the defects in my Toyota Highlander.
