As I pulled out of the Albertson's parking lot, my 2001 Elantra GT automatic suddenly decided not to shift gears. At the same time, the "check engine" light came on steady. After turning the engine off and then restarting, the light was off and the car shifted fine... until about 5 minutes into my next drive, when the same thing happened. Does anyone have a suggestion for this? Because the check-engine light is involved, I'm inclined to think it's an electronic problem vice a mechanical one, but perhaps hyundaitech can help.... --P
You'll have to have it scanned to see what the code is, but the most popular is P0715, input speed sensor.
