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.

2006 Hyundai Sonata Owner Comments

problem #1

Jul 032007

Sonata 6-cyl

  • Automatic transmission
  • 18,000 miles


Complaint centers on a pattern of deceptive and misleading representations by Hyundai dealership in las vegas, planet Hyundai. Car was brought to them shortly after July 1, 2007, with a driver complaint of failure to upshift properly resulting in excessively high rpms. Dealer responded by resetting the computer codes after consulting with manufacturer in California, allegedly. Car was returned to owner with promise that if this reoccurred, transmission would be replaced, as per manufacturers direction. Subsequently, a week later the car was returned to dealer with the same problem. The car has been on the dealer's lot since middle of July, no work has been performed, dealer refuses to replace transmission, and car has suffered extensive body damage while on the lot. Dealer adamantly refuses to perform warranty work on car.
