Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2011 Sonata has a seriously defective engine that seizes without warning. It was awarded the dubious honor of being the first CarTalk / CarComplaints Turd of the Week in late September 2015.

A class action lawsuit was filed in May 2015 against Hyundai that claims the 2.4L Sonata engine is defective. More info here.

2011 Hyundai Sonata Owner Comments

problem #1

May 202010


  • 500 miles


The contact owns a 2011 Hyundai Sonata. The contact stated that the gear selector was placed into the park position; however, the warning light displayed that the gear was not which made it impossible for the automatic doors to lock. The failure occurred intermittently. The "park" warning indicator would correct itself after the vehicle was in operation or when the engine was turned off. The vehicle was taken to an authorized dealer for diagnosis. The technician stated that the failure was related to the gear shift. The part was unavailable. The vehicle was not repaired when the complaint was filed. The failure mileage was approximately 500. The VIN was unavailable.
