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.

2006 Pontiac Montana Owner Comments

problem #1

Montana

  • 20,000 miles

A D V E R T I S E M E N T S

The contact owns a 2006 Pontiac Montana SV6. When the vehicle is stopped and idling, the battery voltage begins to decrease. The vehicle has been diagnosed by the dealer several times; however, the failure continues. Also, when the contact places the vehicle into drive, the RPM's increase, but the vehicle does not accelerate. The vehicle was diagnosed for the failure, but it still persists when the contact attempts to drive. In addition, the driver side door on the vehicle does not properly shut and leaves a one inch gap between the door and the body of the vehicle. The engine will also attempt to turn for 30 seconds, but will not turn over completely. All of the failures occur intermittently and were serviced by the dealer while the vehicle was still under warranty. The current mileage was 38,000 and failure mileage was 20,000.
