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.

Montana 2D 3.4L V6

  • Automatic transmission
  • 100,000 miles

Many complaints on the web including a Canadian class action lawsuit. I am currently trying to push GM to step up for the repair. With the mileage I know it is an uphill battle, but the issue has been present for some time, and GM never notified us that there was any issue. So far, $70 to have GM agree the problem is the lower intake manifold gasket, which they have redesigned.

Van reaked of anti freeze. It never overheated but it needed coolant every week. Ended up replacing the radiator.

Montana

  • Automatic transmission
  • 31,069 miles

The car was leaking coolant, so I paid $2000 the first time to fix the problem only to find out the first mechanic did not replace the part. The second one charged me $600.00 and did the job.
