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.

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.

Transmission slipping since 30k miles. Dealers could never duplicate problems, nor obtain DTC because CEL did not illuminate until 125k. Now trans chatters loudly and can not be driven. 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!!

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.
