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.

2006 Hyundai Sonata with a 3.3l engine is a piece of sh--. valve cover leaks with the oil leaking onto the alternator causing it to go out. Hyundai knows of this problem along with the NTSA and yet no recall. what the heck over, why is there no recall. Does someone have to die before the NTSA will issue a recall... I know for a fact Hyundai wont because it would cost them some of their money.

I had another car (Nissan) the same thing happened to but didn't know the issue was due to leaking valve cover gasket. With it I went through batteries & altenators which tested bad, but they were the end result of the actual problem. IF YOU DETECT OIL ON YOUR ALTERNATOR, CHECK YOUR VALVE COVER GASKETS & replace ASAP before the leak damages anything else. Its a cheap fix that will save you hundreds of $$ if left unrepaired.
