Apparently the side impact air bag wiring harness has too much room to jiggle. This may result in electrical resistance that would apparently illuminate the air bag warning light. In the end you have issues where the side impact air bags on MY 2001 and MY 2002 Hyundai Elantras won’t deploy at the appropriate time. Air bags are supposed to deploy at the appropriate time.
Sometime before the end of the year, Hyundai will be notifying owners to have their cars fitted at Hyundai dealers with new wiring harnesses under both front seats with new connector clips. As of this moment, NHTSA wasn’t sure how many cars would be affected by this Recall. If you think you’re one such owner, contact Hyundai at 1-800-633-5151.
