What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I smelled gas. I opened the hood, removed the engine cover & fuel was spraying from the plastic fuel line, the size of a pinhole. I contacted the dealer to order a new fuel line and was told the fuel line part #25648136 is discontinued, as soon as I find one left somewhere, I will be taking to an independent repair…
When driving on freeway above 60 miles per hour and have to brake heavily it will start to shake and shimmy steering column fixed 2 times this year, as it loosens up and you can move it up to two inches back and forth.
The contact noticed that the fuel tank was fractured from excessive corrosion causing fuel to leak. The manufacturer was notified of the failure. The failure mileage was 68,000.
The contact stated that the front driver side seat belt failed. The contact stated that he attempted to put the seat belt on but it failed to connect. The vehicle was taken to the dealer for inspection but they did not provide the cause of failure, just the replacement part number. The vehicle was not repaired.
Seat belt failure: the seat belt fastener(clasp/hook) on my 1996 buick riviera vin # [xxx] has failed. Insertion of the male end of the belt into the female fastener fails to result in the unit locking. Buick states they have no recall on this issue or any responsibility to repair it.
While driving approximately 45 mph the engine started hesitating. He pulled over to the side of the road, and noticed an engine compartment fire. The fire department extinguished the flames. A police report was filed. The vehicle was towed to a salvage center. The vehicle was completely destroyed .
While driving I noticed a smell of gas. I stopped & was at a truck stop. I checked under the gas tank vehicle & spotted no gas dripping from the tank. Then I went around to front of the vehicle & saw no gas leaking. Then several days later, I drove to fresno, parked the car & told my daughter that I smelled gas.
Electrical (?)--the engine dies while driving at highway speeds. The engine will not restart when shifted to neutral while still rolling but does restart when the brake is applied! This has happened seven times during the past 9 months and is happening with more frequency--4 times this month! The buick service dept.
