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.

Monte Carlo

  • 107,000 miles


The contact owns a 2004 Chevrolet Monte Carlo. When the contact placed oil into the vehicle, oil leaked onto the manifold. The change oil and low engine oil indicators illuminated. The failure recurred four or five times. The vehicle was taken to an independent mechanic where it was diagnosed that the engine oil was dripping on the manifold and the gasket and wiring needed to be replaced. The vehicle was not repaired. The manufacturer stated that the VIN was not included in NHTSA campaign number: 15V201000 (engine and engine cooling). The approximate failure mileage was 107,000.

  • miles
At 2700 miles it blew the engine. Replaced engine and drove home, whole front started on fire. The consumer was informed that the fire was from a gas leak in the pipe. The consumer felt that the fault was due to green Chevy mechanics. Per invoice: The engine light had come on, found codes for engine misfire, cylinder #3, knock sensor melted, performed compression test, cylinder #3 showed zero compression, removed #3 spark plugs, electrode was gone, removed the engine, disassembled the engine down to the pistons, holes were present in the piston, cylinder walls were severely gouged and the engine assembly needed to be replaced.
