While driving in normal circumstances, engine power was lost, and complete loss of throttle control occurred. Car would accelerate extremely slowly, and not past 20-25 mph (presumably 'engine fail-safe mode'?). thankfully not on a high-speed road. Obd code was P2138, indicating a faulty accelerator position sensor, which was replaced by dealer under warranty.

2012 Impreza... bought new, nothing but headaches. All problems listed below occurred before I had even owned the car 2 years. 1. at 8-10K miles - while driving car would randomly turn off passenger airbags and illuminate no passenger seatbelt on the dash. Took car to dealer 3 times. Dealer refused to fix as the "error was not stored in the computer." Suggested cell phone was the problem even though cell phones were not near the seat during each of the multiple incidents. I had to complain to corporate who told the dealer to replace the sensor in the seat. No problems since. 2. at 15K miles - multiple times car would turn on check engine light and traction control light simultaneously. First incident dealer said "dirty camshaft sensor." Second incident I had to refuse to take the car back until they actually fixed a part. Dealer kept car a whole week and made calls to corporate engineers. Tests revealed it was a "failed oil pressure valve." Replaced the part and no more problems. 3. at 25K miles - bad battery. Had to replace when car was only 1 year and 10 months old.

Followed too closely through a double intersection with a non-functioning light. Police officer directed traffic through the intersection but apparently we had to stop before the second intersection. Apparently I slowed down enough that the airbag did not deploy. I indicated 20 but surely my airbag would have deployed at that speed. Was able to drive the car under its own power off the road into a subway parking lot. As I was maneuvering into a parking spot the engine caught on fire. It seems strange to me that if I was going slow enough for the airbag not to deploy but for some components to catch on fire that the car is road worthy. Worth looking into?

The airbags in this vehicle turn off while driving (driver and passenger side dashboard icons indicate airbags are turned off). Vehicle must be stopped and restarted for the airbags to turn back on. There seems to be a relationship to electronic interference - passenger use of iphone or ipad may be involved - but it has happened with no passenger as well. This happened 5 times in one day recently while driving at high altitude (pikes peak, co). Probably related: The seat belt alarm has gone off when iphone is placed on empty passenger seat while driving.
