2009 FORD ESCAPE with 130000. miles

September 10 2014, vehicle was serviced at henry curtis Ford in petaluma california for recall 14s05. Prior to this recall, we had no problems with our vehicle. October 3 2014, vehicle stalled at 65 mph driving on highway. My wife was driving up hill on the highway in the far right lane and was able to pull off the highway to the shoulder. Vehicle towed to repair shop, unable to find any error codes. Vehicle towed to henry curtis Ford dealership in petaluma california where the vehicle was purchased new in 2008. A $145 diagnostic was done and only one error code was reported by the dealer. Code B1239 ( air flow blend door driver circuit failure). Vehicle could be driven as there were no check engine lights on at that time. We picked up the vehicle from henry curtis Ford, and drove home. October 10 2014. Rpm's shifting up and down while driving on the highway at 65mph. Had vehicle towed to repair shop in san francisco. Serviced and replaced parts for B1239 error. Mechanic test drove vehicle and now another error code displays code P2112. P2112 Ford - throttle actuator control system error. The mechanic is replacing the throttle body and reprogramming the pcm. I called the Ford dealership and was told my vin is not covered under any recalls for P2112. When i asked about consumer satisfaction program 13n03, i was told my vin is not included. We had no problems with the vehicle prior to bringing it in for the recall 14s05. Now after that service we are having several problems and i have read that other vehicle owners are also having the same P2112 error. Ford should include our vehicle in this problem and see if the other two incidents we have are related some how. Everyone i spoke to at Ford did not want to help, but continue to charge me more diagnostic charges and repair. Thankfully we have an honest mechanic that is helping us out.

2008 MERCURY MARINER HYBRID with 40211.0 miles

Second unwarned total shut-down of all power on roadway - this one just 17 days after repairs and reprogramming by ford dealership following first instance, which cut gas engine and electric motor power while traveling on los angeles freeway. This power shut-down occurred while trying to pull from parallel park spot onto busy blvd - lost all power 2 feet into traffic, able to roll back into curb before traffic reached me around semi-blind curve. After the first in-use failure on 5-17-10, i simultaneously reported the malfunction to ford customer relations (case# 1432331380), and presented the vehicle for repair to cerritos [the following quotes from text of service record]; tech performed `eec test, revealing fault-codes: B1239, P1A0C and P0562. The tech also "found tsb (tech service bulletin) 07-25-12 with concern resolution" & he "contact[ed] ford technical service hotline with concern." the tech "replaced the auxiliary airflow mode door actuator and reprogrammed the traction battery control module to latest calibration 8m64-10b687-ag. Final eec test passed." i was also informed that the part number for the replacement `airflow mode door actuator' differed from original, so the component has apparently been re-designed - but neither my wife nor i have received warnings from ford that updates/repairs were recommended on either of our 2008 Mariner Hybrids. This originally smelled like a `silent recall' to me...But this doesn't even rate as a `recall', because the work performed did not prevent the second occurrence of the equivalent malfunction just 17 days later. This is a totally unacceptable failure mode for any consumer transportation vehicle, because it occurs without warning, and leaves the driver completely defenseless, and with severely-reduced response options.

To continue the tech's quote: #9999 eps module & electronic steering gear abs wire hybrid blend door hybrid cooling fan kit align battery this is part one -- part two to follow. Lucky you all! I'm sorry to complain as i am a real Ford lover -- have had three tauruses around here in my life and have never, ever been disappointed in them. I thought i would be safe in this car and i know, i know i never will be. I believe i should be given a new car or a good repair and then a solid re-test. That's because i believe in real justice.
