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.

Engine started with a ticking noise when cold. Would go away after engine warmed up. Upon inspection found 2 exhaust manifold bolts sheared on #7 cylinder, 1 broken on #8. ticking coming from exhaust leak on #7. upon research found that this is a common issue with these engines. Why is there no recall or safety notice as it presents a real hazard for fire and exhaust fumes entering passenger compartment.

Tahoe 8-cyl

  • 102,000 miles
I started having problems with my 2004 Chevy Tahoe is September 2009 when the vehicle only had 71,000 miles. The vehicle was using a lot of oil and I took it to the dealership and they notified me that their was no oil leaks and performed a compression test. Since that date I have needed to add additional oil in between oil changes. In the last couple of months it started to use a lot of coolant. I have added about 4 gallons of coolant in the past two months. I took the vehicle to the dealer and was notified that the left cylinder head was leaking coolant in the engine. After further research I found that the castech heads in this model were porous which caused them to crack. The dealer is recommending that the engine be replaced at a cost of $6400. I feel Chevy should be responsible for this repair since they are aware that the problem has to do with the castech heads.
