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

  • 68,000 miles
Driving on interstate for approx 1 hour, when sunroof exploded outwards, no road debris hit the vehicle to cause exploding sunroof, it was not an extreme temperature change. Sound was like a gunshot inside the car, and thankful that the moonroof cover was closed at the time so that glass did not shower into the car while driving. Very frightening and could have easily caused accident. Going rounds with Hyundai right now to get repaired. Dealership stating that Hyundai will not cover the part. Dealership suggesting I file with my insurance company, however this was a fault issue with product, not insurance related. Vehicle under warranty and still having issues with the dealership.

I was driving on the highway heard what sound like an explosion. Almost wreck the vehicle from the noise it made. My children started to scream and cry. Then I heard glass flying off my car. Pulled over to see the sunroof was shattered into a millions pieces. I call Hyundai and was told the only sunroof recall they have is for the veloster which from what I was told was the same thing that happened to me. I have not received a call back from the dealership in regards to my concerns about this issue.
