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.

This car has had several issues the newest being it started using excessive oil just after the main computer was replaced. This car has had regular maintenance at the proper times and never used a drop of oil. When it started using oil it used five liters of oil in just 24 days or 2000 miles. It continues to use a liter every two days. Dealer has know idea why this is happening but the car is burning it, the white exhaust is very evident.

My 2005 Cadillac Cts just hit 63,000 miles started to hear a chatter under the hood went to go get a diagnosis and said timing chain and crankshaft balancer need to be replaced. Another issue is the airbag bag sensor went bad causing the airbag light to keep popping up on display and now needs replaced. I'm hoping we get enough people that have these problems file a complaint in order to get a recall.

This complaint is pertaining to the 2005 Cadillac Cts 3.6L V6. The problem pertains to the timing chain failure of said car at around 80,000 miles. Having done research on the internet I have come across many owners with the exact same problems spanning the 2004-2007 model years, with common failure rates spanning 20,000, to 80,000 miles. This has cost me personally over $1,000 in parts plus my own labor. It has also come to my attention that GM has issued multiple tsb reports pertaining to this problem but will however not acknowledge affected customers. The company still insist that this vehicle(specific engine) is service free up to 100,000 miles, and makes no recommendations for other that routine service (oil & filter). This being said I am requesting that the NHTSA perform an inquiry in the frequency of these problem and encourages GM to acknowledge and compensate customers accordingly.

The contact owns a 2005 Cadillac Cts. The contact stated that the ECM (engine control module) failed three times. Two of those times, the dealer performed repairs. While driving 50 mph, the tire flattened. Cadillac refused to come out and make the repair. The contact stated that the failure was supposed to be covered under warranty. Another issue was that the low tire pressure system failed to indicate when the pressure was low. The contact was concerned that the winter weather conditions could cause the failures to worsen. The powertrain was unknown. The current mileage was 17,000 and failure mileage was 3,615.
