My 1999 buick park avenue was parked under our pole barn in front of our home. My neighbor came over to borrow my car with my permission. It was cold that day. She turned the key. The car backfire & the hood jumped. The car made a loud noise & smoke started rolling out from under the hood of my car. She popped the hood & got out of the car. By the time she got in front of the car flames were shooting out of the front of the car. She called the peru fire department who came out & pulled my car out to the driveway saving our house from burning to the ground. The got the car put out eventually but it is destroyed. Entire engine compartment is burned out. Parts of the inside are melted. The car is a total loss. We contacted buick. They offered us $1000. For a car we were offered $3000.00 for that summer. They then decided they did not owe us anything as the car itself was over 10 years of age. They will not answer calls nor will they pay for the damages. We cannot afford an attorney.

Sudden engine failure. I own a 99 buick park avenue ultra that has about 65,000 miles on it and is well maintained. The car is only utilized about 6 months out of the year since we are snow birds having returned from the east 2 months ago. Last evening as I drove north and up one of the long hills on the toll rd 73 in orange county, ca I experienced the sudden and total loss of engine power while traveling between 65 and 70 MPH. All electrical systems, headlights, dash lights etc stayed on and appeared normal. Fortunately the traffic was such that I was able to pull over to the side of the road, stop and turn on my hazard warning lights. I sat for a moment and then tried to restart the engine. The cranking appeared normal and the engine immediately started and the engine parameters, temperature, volts, etc appeared normal. I was surprised to say least but we decided to start moving again and proceeded to drive pretty much at normal speeds without a hiccup the 20 miles left to get home staying in the rh lanes for the most part. Getting back into the fast moving stream of traffic was somewhat hazardous in and of itself. Prior to this sudden failure there was no warning or change in performance. The only caveat to that is that it seems lately there has been a minor but noticeable sag or hesitation when starting to accelerate while in drive and at highway speeds.

My 1999 park avenue suddenly started to run ruff, causing me to take the vehicle to a gm dealer who replaced the spark plugs and wires, as well as two ignition coils. He stated that the plugs had indication of burns that are attributed to anti freeze coming in contact with the plugs. During the repair he also indicated that he noticed anti freeze on the outside of the engine in the area of the plenum. The repairman stated that this is a common problem with the 3800 motor, that the plenum leaks causing associated problems due to the anti freeze coming in contact with engine components. He also stated that this problem can lead to engine failure if not corrected by replacement of the plenum and the intake gasket.

Plastic intake manifold failure occurred on 1999 buick park avenue with approximately 45,000 miles. Coolant leaked into the engine and resulted in a misfire code in multiple cylinders. Symptoms experienced by the driver were a rough idle at start for 30 seconds, and the service engine soon light would come on, sometimes staying on and sometimes extinguishing after 15 seconds. The car was immediately driven for service. The dealer initially diagnosed the problem as a combination of dirty fuel injection system (cleaned regularly, but still needed to be cleaned again to convince dealer to rule out this problem). When problem persisted in cylinder #6, the problem was then diagnosed as a faulty fuel injector which was replaced. When the problem persisted, it was noticed that coolant had gotten into cylinder #6 in small amounts and cause a misfire. Dealer then diagnosed problem as the plastic intake manifold. Web searching reveals that this is a chronic problem as the design was changed from metal to plastic. However, there are no current recalls on this issue. Cost to repair is approximately $1,700.
