| Gasoline Fuel System problems |
While driving in normal circumstances, engine power cut out, and complete loss of throttle control occurred. The car could only accelerate extremely slowly, and not past 20-25 mph. Thankfully not on a high-speed road. Managed to get home (barely), car worked fine the next day. Dealer found obd code p0128, reprogrammed ecm to remove the code. The same problem had occurred ~1 year previously due to a faulty accelerator position sensor (NHTSA complaint recently filed). Dealer claims causes are unrelated. This can be a serious safety concern if it occurs on a highway, we no longer feel safe driving this car.
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.
