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.

2009 Hyundai Sonata Owner Comments

Hyundai Sonata 2009 limited front loud thud noise when going over small bumps and when turning right. The thud noise is only from the passenger side front strut. There is a big difference when you hit a bump on the drivers side and the passenger side. Is a pretty obvious noise. Dealer replaced right strut and insulator and the noise continues. Dealer say they cannot just change out parts unless they find a problem. Car acts like the front suspension is coming apart when turning to the right and going over small bumps. Problems is a safety issue because something seems to be falling apart on the front end when turning and while going over small bumps.
