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.

2003 Cadillac CTS Owner Comments

problem #1

Dec 222008


  • 66,164 miles


The contact owns a 2003 Cadillac Cts. The contact stated that the PCV passage froze and caused oil to spill onto the exhaust. He called the local dealer and was informed that the pav passage was faulty. The dealer redesigned the PCV passage in the vehicle. Three months after the repair, the PCV passage began leaking again. The contact called the manufacturer about the leak, but has not received any feedback from the manufacturer or the dealer. He feels this is a safety issue because the burning oil leaves a toxic smell in the vehicle, and the leaking could cause the vehicle to shut off. The current mileage was 67,000 and failure mileage was 66,164.
