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.

CarComplaints.com 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.

A D V E R T I S E M E N T S

Unable to shift the car into drive from park. While stopped at a red lift the car failed to accelerate when pressing on the gas. Had to place the car in park and turn it off. When car was started again it failed to be placed into drive. Had to keep restarting car to get it to shift into gear. ESC light comes on when this happens and safety on even after able to shift into park. ESC does not work properly when this occurs. Car does not handle properly while on ice, snow or wet ground.

Loss of power, car shuts down, 'check charging system' alarm/chime with alarm symbols on dash display for battery, check engine and wrench icons. Have to pull off the highway somehow (in midst of heavy traffic) to shut car completely off and restart. On third incident (one day after second), car would not restart for 10 minutes and check engine icon remained lit. Every incident has been while traveling at high rate of speed in commuter highway traffic. Very frightening and dangerous experience for driver and safety hazard to others when it occurs.

Sonata 4-cyl

"ESC" light activated intermittently over past four days. Suddenly brake switch failed, resulting in brake lights failing completely. Unable to start the vehicle (since that requires brake pedal to be pressed, and brake switch failure means car doesn't know pedal is depressed), and unable to switch gears at all for same reason. This failure has occurred on two separate Hyundai Sonatas I have owned (a 2006 and now a 2011) more than a dozen times. The most recent time was in this vehicle, 28 days ago. This failure is known by Hyundai, but still requires a time and money investment to fix, I have lost hundreds of hours of my time to fix this problem which has never been mitigated. I had to pay out of pocket for the first several brake switch replacements, they have since been covered by the dealer. Hyundai says they have developed a new brake switch which was supposed to last longer, but the failures persist.

The "ESC" indicator light (not the "ESC off" light) frequently comes on and stays on. If you stop the vehicle and put it in park while this is occurring, the gear shifter will not work. You can not put the car in gear. Once you turn off the car and restart it, the light goes off. However, after 10-15 miles the light comes back on and stays on again. Dealer ran computer check and found no codes but the problem continues. I've had the car 2 days.

Sonata

I have a turbo limited Sonata. It has a severe left pull. If I am driving on a flat surface and let go of the steering wheel, I would be off the road to the left in about 5-6 seconds. If I am accelerating, I would be off the road within 1-2 seconds. It is a real problem. My dealership does not have the specs to fix the issue. I called the next closest dealer and they also do not have a fix. I am constantly assured that Hyundai is working on the issue, but lets face it, it has been over six months. I have lost faith that they are working on a fix. The newly sold 2011 Sonata limited turbos are being sold with the 17" wheels, not the 18" wheels I have. Therefore, it looks as though they are trying to change it to fix the problem. But what about those of us with the 18" wheels" do we have to wait until someone dies before this gets fixed" that is not acceptable to me. There are already over 165 complaints and I hope more are added daily. I am a repeat Hyundai Sonata buyer and very discouraged with the quality of safety in this car. Please investigate the problem and force a recall!

Engine stalled at highway cruising speed without any warning. The engine lost most of its power. Check engine and ESC (traction control) light were on. Restart the engine appeared to resolve the lost power problem but check engine light were still on. This happened twice within three weeks while driving on a busy highway and was quite dangerous. Dealer was able to reproduce the problem and replaced the electric throttle control module.

Sonata

  • 11,000 miles
This incident occurred with a 2011 Hyundai Sonata limited: 6 months of perfect operation and approx. 11000 miles. Violent shaking of steering wheel and steering column after acceleration onto an on ramp. Immediate and entire failure of steering with violent and extremely loud shaking and vibrating of steering wheel. Shaking continued even after ignition shut off. Occurred for 20+ minutes. Disabled only by disconnecting battery. Blisters on hand from hanging on to steering wheel. Nothing could be done to steer, operate, or control vehicle. This incident occurred without warning and within seconds. Towed to dealership. Kept for 3 days. Could not replicate. Steering column recall performed with steering software update, ESC reflashed, reprogrammed eps. Hyundai was excellent in their response - both dealership and Hyundai usa. Hyundai usa engineers and tech's were involved with resolving the problem. This was a frightening and dangerous incident and possibly life threatening. Whether repair attempt will resolve only time will tell.
