Vehicle started and excelerated and caused a lineup of crashes.Update on throttle could have minimized or prevented, but hearing the problems others have had and considering not updating. First five years vehicles brakes and exhaust were sorry. Have replaced all with after-market stuff and all problems have stopped. Jeep should consider better equipment, especially because trucks generally are used to pull trailers such as me. Still want my parking brake fixed. I would like a reliable hand brake as in some models.
The throttle position sensor is not functioning properly in my jeep. I found that tere are 3 service bullitens requireing the replacement of the same. There is also one recall indicating the part should be replaced. I called up jeep (chrysler) they said that the recall does not apply to my jeep. It was made during the months listed in the recall and the serial number on the sensor applies the the list in the servoce bulletins. I initiated a case with chrysler the complaint # is 55441434. Please clarify this issue if you can asap. The jeep is dangerous to operate, because of this malfunctioing sensor.
When driving the accelerator sticks all the time . Please describe . *Ak
