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.

  • 39,000 miles


The contact owns a 2004 Hyundai Sonata. The vehicle had water damaged due to a defective air conditioning hose sealant that allowed water to penetrate which caused mildew to form on the interior of the vehicle. The dealer stated that the instrumental panel will need to be removed in order to replace the damaged wiring and sealant. The contact stated that a year ago water penetrated the interior of the vehicle due to the sealant around the brake lights. The VIN information wasn't available. The manufacturer will be contacted. The failure mileage was 39,000 and the current mileage was 69,000.
