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.

CarComplaints.com Notes: Engines shouldn't need a new quart of oil every 500-1000 miles, but for thousands of Suburban owners that's exactly what's happening. Engine oil consumption on aluminum block engines with Active Fuel Management (AFM) is out of control and owners are left looking for answers.

The most likely culprit is an uncovered AFM valve which, in many cases, can be covered under warranty. The problem is the issues don't stop there and many owners have been told by GM just to buy a new engine. Take one guess who they want to pick up the tab.

The contact owns a 2007 Chevrolet Suburban. While attempting to start the vehicle, it began to shake and the check engine light illuminated on the instrument panel. The vehicle was taken to the dealer, but the failure could not be duplicated. While driving at various speeds, the vehicle began to slow down and the reduced engine power indicator illuminated on the instrument panel. As a result of the failure, the vehicle was almost T-boned by a tractor trailer. The vehicle was able to be maneuvered to the side of the road where it was restarted successfully. The vehicle was taken to the dealer where it was diagnosed that the throttle body and the brake switch would need to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was brought back to the dealer where it was diagnosed that the wiring to the ECM connector 2 and wiring harness needed to be changed. The vehicle was repaired, but the failure recurred shortly after the repair from the dealer. The manufacturer was made aware of the failure. The failure mileage was 67,200.

I started my car and the brakes were gone and the steering wheel was locked up. I turned it off and started it again, then the brakes would lock up and there was no power steering. I waited a while and tried a third time, it made a power steering machine noise and was back to normal. I was afraid to drive it because I didn't want to cause an accident if it happened again. I had it towed to the dealer. The dealer could not reproduce the problem, therefore could not use my extended warranty to fix it. I paid out of pocket for a new power steering pump, because I will not drive it if there is even a chance of that happening again. It's too much of a liability.
