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.

2001 Buick Regal Owner Comments

problem #1

Mar 272008

Regal 6-cyl

  • Automatic transmission
  • 78,892 miles


Dealer says lower intake manifold leaking. Repaired at 61,549 mi. Dealer says lower intake coolant bypass is leaking, as is, the valve cover gaskets. Claims there have been engine fires and that GM has a recall, but not a remedy for the problem, as of yet. Repaired gaskets at 78,892 mi., total cost for both $1,600. 1. one would think after building cars for 50 yrs. That a head gasket could last 200,000 mi. 2. my gasket lasted 17,000 miles between repairs. The leaking gaskets are a direct cause of the engine fires. The oil leaks down on top of the exhaust manifold and bingo, "fire". they say they have to come up with a better heat shield "duh". I bought the car based on consumer reports. I've had other problems too. I just wonder if GM will step up and reimburse me.
