Power Train Problems of Buick Park Avenue

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.

The heater in the seat quit working. A new one was installed and it doesn't heat up correctly. The motor in the window failed. The rotors/brakes were warped. The stereo failed. The window will not roll up correctly despite a new one being put in. The starter is dragging. Some of this was covered under the Smart choice extended warranty. However some of the repairs are still needed and I still have time remaining on my Smart choice warrranty but they have went bankrupt and my dealer says the warranty is no longer valid and I will have to pay for any repairs done.

At speed let of gas pedal real quick to brake and engine completeltshutsoff. Does not do it all the time never know when it will happen. Happens at any speed whats bad dealers cannot find any code in computer telling whats happening. They want me to bring it in right after it happens. It happens that way.

Consumer experienced a hard time reading the speedometer due to the location and the design. Also, when driving at highway speed consumer is unable to verifiy how fast the vehicle is traveling due to the location of speedometer.
