2004 Hyundai Elantra Problems

Transmission Won't Shift/CEL Due to Failed Speed Sensors in Transmission

If the automatic transmission does not shift properly and the Check Engine Light illuminates, the speed sensors in the transmission may have failed. The sensors are simple and inexpensive to replace.

Power windows stopped working.

My power windows won't work. Power locks function well but the buttons for my windows won't.

Check Engine Light Due to Failing Canister Purge Valve

A failing vapor canister purge valve may cause the Check Engine Light to illuminate. This valve is part of the evaporative (EVAP) emission control system.

Dealer says trans is bad. CEL now on. Dealer and Hyundai refuse to repair the car and decline to acknowledge prior trouble because CEL never came on!! Rust in sunroof area coming from inside out and paint peelin...
I bought this car new and had a small problem with the transmission right from the start. It was very subtle and hard to detect and, in fact, it would not show up on the computer but I knew something was not right.
