| Description of the problem | I am approximate on the date without going back to service files. The car was new to me at the end of january 2014. Then in mid-march, a couple of thing were happening. The crash avoidance alarm would go off for no apparent reason. Then, inside of a couple of weeks the car lost all ability to accelerate. First time i was in the middle of an intersection. The other two times, open road, in early morning so luckily little traffic. In all 3 cases of the acceleration loss, i was able to coast to the shoulder. It is not as if is a drive train issue... If you press on the gas as you are coasting, the engine is just idle. Does not rev. Once stopped completely and restarted, everything was fine. The dash warnings that came up were "inoperative. See owner's manual" (no lie?!) and then "presafe functions limited. See owners manual." conditions were clear in all cases. Speed at the time of incidents, once 15 mph, twice around 40 mph. I took the car to the dealership. They had for 2+ weeks and the issue would not replicate itself. When i picked up, i was told there was an "update" that was done and maybe that would prevent it from happening again. It did . . . Until two weeks ago. Fast forward to january 2015. The same thing has occurred 3 times in two weeks. Two times inside of 15 minutes in one case. Once in a very risky merging traffic situation. I am writing this on the day that the last two incidents took place. Taking the car in tonight. I really don't want the car back until i know it is fixed or they just replace it. I find it very odd that this has not occurred for approx. 6 months now a rash of the incidents. I am so thankful this has never occurred in heavy traffic. I'm gun shy now. |
