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.

2004 Buick Rainier Owner Comments

problem #1

Jun 202007

Rainier 6-cyl

  • Automatic transmission
  • 46,403 miles

With vehicle temperature at normal range, in park and at normal idle when I push on the gas pedal the RPM would drop to under 500 and then go back up, almost like a hesitation of sorts. Took vehicle to Buick dealer and was told that it was the secondary air pump, basically the egr valve. Was told this was part of the emissions of the vehicle but not covered under the emissions warranty nor would my extended warranty cover as well. Vehicle has 46,403 miles on it.
