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.

LeSabre 6-cyl

  • Automatic transmission
  • 56,700 miles


My 1998 Buick Lesabre started to smell of anti-freeze earlier in the day on 4/27/04. The car was parked for most of the day, quick trips to the store at most. When I got home that night, the car was shacking and pouring exhaust vapors out of the exhaust pipe. In the morning on April 28T, . it started just fine. So, I drove it to my mechanic. The car ran smoothly for about 200 yards, then it progressively got worse, until I was practicly coasting when I reached my mechanics. After they looked into the issue, they concluded that the intake manifold was cracked and had spewed water into my engine. This left water in my oil and no coolant. My mechanic flushed my oil, flushed my coolant, replace the manifold with the factory part, and replaced the gasket with the factory part. My mechanic told me that this was a common issue and that all of the 3.8L GM engines had plastic intake manifolds. I then began to research on line this issue, and apparently many people have had the same problem. I called Buick 3 times trying to plead my case. Each time I was told there is no recall for this car, but the model 2 years prior had the same issue and the part was recalled. I have found a notice that NHTSA is trying to have the replacing the "delphi fuel pressure regulators" replace, which can cause the intake manifold to crack. NHTSA recall campaign number: 04V090000

LeSabre 4WD 6-cyl

  • Automatic transmission
  • 48,000 miles
My 1998 Buick Lesabre had a ruptured manifold in June 2003, causing engine to cease and smoke and minor fire. The smoke made myself and my infant son very ill. This was reported to Buick but they refused to reimburse for repair since vehicle was just out of warranty. They told me that the following recall was not in effect: NHTSA recall no. 03V473/GM recall no. 03054 and that my vehicle had no recall. A few months later the engine ceased to start again and it was determined at the Buick dealership that it was a faulty fuel pressue regulator which was replaced. Buick again refused reimbursement although I brought their attention to the current recall on my vehicle. I called again today as the recall for 98 Buick Lesabre with V6 engines was again posted but Buick told me that their system has no such recall and they refused to reimburse me for over $1000 of repairs for the faulty fuel pressue regulator and manifold. NHTSA recall no. 04V090/GM recall no. 03054B.

I am upset that the GM recall # 03054B does not include the 1998 Buick Lesabre, only the Park Avenue, according to the customer service dept. For Buick. My Lesabre did the same thing as described on the recall results for the Office Of Defects Investigation found on the internet. However, your office did list it using NHTSA campaign id number: 04V090000. Please E-mail me @ or leave a message for me @ 850-482-8156, if my vehicle (1998 Buick Lesabre, custom) can be added to this recall. After looking at the reviews for this vehicle it seems there are a few complaints. Thanks
