problem #4

Impreza 4-cyl

  • 18,000 miles


Driving about 30 - 35mph when all of a sudden the car lost power. The car did not stall, but engine went down to idle speed and my accelerator pedal had no throttle control. The "check engine " light came on as well as the "traction control" light. I drifted to the right shoulder of the road and turned engine off. After opening the hood to check engine - observed nothing unusual - I re-started the car. The car seemed back to normal, but the engine code lights stayed on. The warning lights eventually turned themselves off - 3 or 4 re-starts later. Subaru dealer reported a P2138 obd code, but he did not replace/repair anything. The same exact thing happened 9 months later (July 2, 2014), and Subaru dealer reported a P2138 code once again. No repairs or replacements done!

My daughter was driving the car after getting off work at !:30 am when the engine stalled and the car would not restart. From time to time since I purchased this car new, the engine would sputter while driving. It turns out that there was a cut in the fuel filter. Our mechanic said it was unlikely that it happened any time except when the filter and fuel pump were installed by the manufacturer. There are many complaints about this car using oil...mine does too.

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.
