2003 Hyundai Elantra ProblemsTransmission 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.
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.

2003 Hyundai Elantra RecallsHyundai Recalls Certain 2001–2003 Vehicles Due to Corrosion on Front Lower Control Arms
Hyundai is recalling 2001–2003 Elantra and Tiburon vehicles in areas of the country with heavy concentrations of road salt usage. Corrosion and thinning of the steel in the front lower control arms may progress to a point where the panels become perforated, which can cause a fracture between the ball joint and pivot attachments to the chassis. This could reduce driver control over the vehicle, which may increase the risk of a crash. Dealers will inspect and replace the affected front lower control arms.
