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.

My cylinder head intake and exhaust valves were severely out of GM's.0037" maximum wiggle tolerance. The valves were tested by yuma auto and trans as well as american heritage performance (harbor city, ca). Not addressing the issue may have caused a dropped cylinder valve and blown engine.

Submission from constituent re repairs on his 2007 Chevrolet corvette (the engine "dropped a valve") the consumer was informed, the entire engine needed to be replaced at a cost of $18,722. Instead of replacing the engine, at no cost to the consumer, General Motors offered to pick up 45% of the cost, leaving the consumer to pay the balance of $10,630. The consumer stated GM issued an internal bulletin as far back as February 2008, that showed they were aware of the Z06 engine failures and short life expectancy.

problem #2

Feb 172013


  • 16,000 miles
Exhaust valve guides are excessively worn beyond service limit. Approximately 4 times service limit. This is a definite safety hazard to me and to those around me. The worn valve guide causes the exhaust valve to stretch, and eventually break. When the valve head breaks, it beats its way out of the engine, causing potentially: Engine lockup, oil spill on highway, large smoke cloud and debris out the rear of the vehicle. Loss of control of the vehicle imminent danger to those around me due to loss of vision and slippery roadway. This issue affects all 2006 to 2013 Chevrolet Corvette Z06.

- Santa Fe, TX, USA
