Power train:axle assembly:axle shaft
Problem: Hyundai Motor America (Hyundai) is recalling certain 1.6 liter model year 2015 Sonata vehicles manufactured August 29, 2014, to October 28, 2014. The affected vehicles may have been assembled with an incorrect left axle shaft which may result in the shaft separating from the transaxle differential.
Risk: If the left axle shaft separates from the transaxle, the vehicle may stop moving, increasing the risk of a crash. Additionally, a separated axle shaft may allow the vehicle to roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Fix: Hyundai will notify owners, dealers will inspect and replace the axle shaft, as necessary, free of charge. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 126.
