What 1990 Buick Lesabre owners say
Most recent owner complaints, unedited.
This all happened over a period of the past 5 years, I didn't know this site was available, so submitting now.
While the engine is running there is a constant sound of air escaping. There is an anticipation of the vehicle back firing at all times. Also, intermittently vehicle will stall, and use twice as much fuel.
I have a 1990 buick lesabre that is equipped with tilt wheel. About a month ago the steering column became extremely loose...I had never had this problem before. Anyway, I thought "well, the car is just aging" and didn't think to much about it until yesterday. My son was climbing across the drivers seat and accidently hit the gear shift selector. Without the key in the ignition and the steering wheel locked, the car went into reverse and proceeded to roll down the driveway. After we got the car stopped, I discovered that even with the steering wheel locked, the car can be placed in any gear without any resistance. This is extremely unsafe and is the equivalent of the old powerglides that would do the same. Luckily no one was hurt, but the likelihood of this happening again to someone else is very likely. I can't understand why it suddenly started to do this. Thank you.
The brakes on a 1990 buick lesabre failed in the dealer lot when I went to test drive the car. They assured me they would repair the brakes and call me when the car was ready for sale. After the repair, I purchased the car, but the brakes soon failed again. I then discovered that the brake line repair had been made with compression fittings instead of high-pressure inverted-flare hydraulic fittings. I suspect this was unlawful. I contacted general motors, and the agent I talked to doesn't seem to comprehend that the use of compression fittings in a brake line is unlawful, and trivializes my concerns since I bought the car "as-is".
When the vehicle was started it suddenly accelerated and caused an accident.
Vehicle experienced sudden acceleration, crossed a roadway, and crashed into another parked vehicle.
