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.

Have seen the recall notice on Sonata 2011-12. I have a 2010, manufactured in Alabama. The motor went out in the car a few months ago while I was driving. It lost power and stopped. The car continues to sit in my driveway. I had the dealer inspect it before it went out because of a knocking noise. The dealer (mungenast Hyundai, 649 dunn rd., St. Louis, mo) reported it was a motor problem and the only way to fix it was to replace the motor. The warranty had already expired, and I did not have $5000 to replace the motor. The motor problems did not start with the 2011 models. I hope you can look into this, and hopefully I can get my vehicle repaired. Thank you.

Delays in acceleration linked to a computer program that controls the transmission, shifting from 1st to 2nd gear automatic transmission, there may be a 2 to 3 second lag in acceleration due to the transmission control module programming or transmission.

As I was driving to make a turn the car shut down without warning. It has happened two other times sine this first incident. Car shut down as I was going various speeds. The cranking of the ignition is also a problem. I first reported this to the dealer in 2011. It cranks as if it is about to die then it has eventually caught and turned on. This is an ongoing issue. Since it doesn't show a code or act up when I am in for service they do nothing for me.

The dealer refused to perform warranty work when the check engine light came on unless I agreed to pay a fee of approximately $125 if the dealer decided that the work was not covered by the warranty.

My 2010 Hyundai Sonata completely shut down on me 2-times in less than 5-minutes times while I was driving today. I was on my way to enter the expressway. The power steering and everything just shut down. My car just made a sudden stop. Thank god I had not entered the expressway and took the side streets home. I feel that this is a real safety hazard to myself, the passengers riding with me as well as other drivers, passengers and families on the road. My vehicle has 53,215 miles, there is no way this should be happening. If this is happening to my vehicle, I know it's occurring in other Sonata's and other Hyundai vehicles base on what I see in online entries on the 2010 Hyundai Sonata and Hyundai vehicles. Manufactures must be held accountable for the defected products place on the market. I know that I'm a small voice against a large corporation, but if you take the time to investigate I know that my claim will be validated. I hope and pray that something is done about this before we are dealing with injuries or fatalities. I am a frustrated and unhappy Hyundai Sonata owner, looking for Hyundai to put safety first!

I went out to start my car and it wouldn't start. I had to call a tow truck after a jump wouldn't work. I bought the car a year and a half ago and when the driver tested the battery, it wasn't dead but it wasn't great. I replaced the battery ($95 at walmart) and the car started. For a day. The next day the car wouldn't start again, when we realized it was then the starter. I purchased and installed a new starter on the vehicle ($105 online) issue resolved. Pretty young of a car for the starter to go.
