    POWER TRAIN:AUTOMATIC TRANSMISSION

    Hyundai Motor Company (Hyundai) is recalling certain model year 2011-2014 Sonata vehicles manufactured December 11, 2009, through May 29, 2014. In the affected vehicles, the transmission shift cable may detach from from the shift lever pin.

    Risk: If the transmission shift cable detaches, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver parks the vehicle, despite selecting the 'PARK' position, the transmission may not be in 'PARK.' If the vehicle is not in the 'PARK' position and the parking brake is not applied, there is a risk the vehicle will 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.

    Remedy: Hyundai will notify owners, and dealers will inspect and, as necessary, repair the connection between the shift cable and shift lever, free of charge. The recall began in September 2014. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 123.

    I was driving. The tailpipes started smoking I checked engine oil and it was almost empty. No check engine light came on. The engine could have locked up on me on a state hwy that has a 60mph limit! No warning light. No low oil light. No lights came on at all ever. The car still doesn't have any light on but has oil consumption like I've never experienced. The engine was replaced in 2019 and only has about 63,000 miles on it.
