2009 Hyundai Elantra Problems
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.
2009 Hyundai Elantra Recalls (Recent)
RepairPal Expert Overview:
An electrical connector for the passenger front seat weight sensor is located under the center console. This connector can become contaminated, which could cause the passenger front air bag to deploy unnecessarily in the event of a crash. An unintended air bag deployment increases the risk of injury for an occupant in the front passenger seat. Dealers will install a protective cover over the affected connector to prevent contamination. This recall is expected to begin during April of 2011. The Hyundai recall number is 099.
RepairPal Expert Overview:
The affected vehicles are being recalled because the brake light switch can fail prematurely, resulting in the loss of brake light operation. Other systems that may be affected include: cruise control, push-button start, gear shifter, and Electronic Stability Control (ESC) system. Dealers will replace the brake light switch to correct this concern.

2009 Hyundai Elantra Reviews
Love my Elantra Touring but an having issues with the clear coat on exterior handles and now the mirror peeling. Hyundai has covered the handles but are now not covering the mirrors. Very disappointed in how I am being treated. I do not take it to be washed often. They stated that they have never seen anything like it before. Where else is the paint going to start peeling on my red car? Anyone else having this problem?
