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.

2007 Chevrolet Suburban Owner Comments

problem #1

Mar 252008

Suburban 4WD 8-cyl

  • Automatic transmission
  • 9,545 miles

While driving approx. 20 miles an hour there was a loud thud and the service engine light and the traction control light both came on at the same time. The engine began to miss on acceleration and shifting between 1st and 2nd gears was so rough it shook the truck. The truck is only 6 months old and has 9, 000 miles on it. The Suburban was driven to the dealership for repairs it took 3 days for them to diagnose computer relay was affecting the traction control system and #7 cylinder had seized. The entire cam shaft is going to be replaced. Est. Work will take 7-10 days.
