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.

Purchased a 2009 Sonata in spetember of 2008, the air conditioner does not drain and has developed a mold smell when air is on. Returned to dealer, they want to "clean" evaporator with a foam cleaner at a cost of over $100. The tech said to drive car in the outside air circulator and not the recycle air engaged, since I refused the "cleansing". this making me sick, friend has a 2009 Santa Fe with same issue.

New car was delivered to me with a major engine oil leak. Could have resulted in engine failure and loss of control. Engine was replaced but has caused power train vibration and strong odor when the engine is warm.
