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.

Sonata 4-cyl

  • 6,100 miles


The first incident occurred in a thunderstorm: "check charging system" warning lit up and alarm sounded. Car lost power. Had to pull off on the side of the highway. Restarted the car and it was fine. Called dealership and was told it was "water on the serpentine belt and not to worry about it." Second incident was approx. 1 week later when the "check engine" light came on along with the "check charging system" light and alarm and car lost power. I pulled over on the side of the highway. Turned car off and restarted. Third incident, a couple of days later, "check charging system" alarm. Same scenario. Took to dealership. They conducted a system download to onboard computer. Now it is a daily occurrence. Couldn't get out of the driveway today after restarting the car 4 times. Will be contacting dealership tomorrow.

The sun visors are not long enough (vertically) to prevent the sun from hitting center of windshield area and blinding driver. I've had to stop several times to regain my control and my clear view. The car was purchase on 12/19/10 and at the time I noticed that the sun shield that they sold me at the dealership would hardly stay in place because of the vertical shortness of the sun visors but when the hour was changed to daylight savings time is when I really realized the severity of the problem at the time of the sunset. Even raising the driver's seat all the way up it is impossible to avoid being blinded by the sun; it's an accident waiting to happen. I have notified the consumer service department of Hyundai but have not received a reply. Thank you for your assistance.

Car pulls to the left since brand new. Very noticeable when driving at a high speed for a length of time. Constant right pressure must be maintained on steering wheel to prevent car from moving to the left. At a slow speed on back roads the pull is not that noticeable. For some reason, when taking a right turn off a highway ramp, the left pull increases, which requires increased right pressure on the steering wheel. Have had car checked at dealer, alignment was checked, and told everything is fine. Researching the Hyundai forums, it appears my Sonata is not the only car experiencing this problem, and as of this date, Hyundai/Kia have no fix, or even acknowledge their is a problem.

The steering pulls to the left, & somtimes to the right. I have to struggle to keep the car from crossing the center line while it pulls to the left. Steering has wandered since car was new. Feels unsafe to me. I took car back to dealer at 949 miles. They did re=alignment car still pulls, took car back 3 more times to dealer for same steering pull, dealer acknowledges the sever pull, they installed a factory suggested camber kit, car still pulls & wanders. This car is unsafe & should have a recall.

The contact owns a 2011 Hyundai Sonata. While driving approximately 35 mph, the contact smelled an extremely strong toxic odor emitting from the interior of the vehicle. The odor did not subside at any time. The vehicle was taken to an authorized dealer three times. The technician attempted to correct the failure by placing coffee grounds in the trunk, on the front and rear passenger seats as well as the drivers seat but to no avail. The dealer offered to trade the vehicle for another however, the contact stated that the manufacturer did not adhere to the agreement. There was significant concern of a potential health and safety hazard. The VIN was unavailable. The failure mileage was approximately 11.
