2004 Hyundai Elantra Problems
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.
Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.

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. Finally, after the warrenty was up, it got bad enough to cause the CEL to come on and the problem showed up on the computer. It was the transmission module. Other than this it has b...
Brakes started pulsating at 75,000 and had to replace the front rotors and pads. Otherwise, have had no problems at all with this little car.
