2000 Buick LeSabre Owner Comments

problem #6

Mar 302007

LeSabre 6-cyl

  • Automatic transmission
  • 64,800 miles


March 30th, 2007 car ran rough and service engine soon light came on. A bad odor also was permeating into the car while going down the road. Car went back to the dealer on the 31st and they had the car until the 3rd of April. I drove the car about two miles and the car did exactly what it was doing before when I dropped it off. I dropped the car back off the next day on the 4th they had it until Saturday the 7th. They said they changed the spark plugs and that was what was wrong. I drove the car and everything was fine until Friday the 13th. I went to start the car in the morning and it wouldn't start right away. When it did it stunk so bad from to much gas from trying to start it. I ran it that day and it ran rough a few times and didn't call the dealer. I loaned my car to my brother Friday night and I didn't tell him about the starting problem or the running roughly. He went to start the car after work on Saturday morning and it wouldn't start right away for him. He got it going and he told me that it ran rough and bucked and jerked. When he brought the car back to me it sat in my driveway for about four hours. My wife went to start it and put it into the garage for the night and she could not get it to start she had to come and get me to get it going. I called the dealer on Monday the 16th and they told me to bring it in the next day. I did so and they sent it to a garage to have it looked at. About 2:00 on Wednesday the 18th I stopped to see if it was fixed and they said it was that it was the spark plugs again the garage didn't put premium plugs in. They told me that they washed my car for my inconveniences. Also the fuel mileage on the car was 20 mpg which is extremely low it should get 30-32 mpg. I told them this also. So I got the car back and today the 19th of April the car is having problems running properly. I returned the car and they wont call me at all. I feared my children's safety in this car.

LeSabre 6-cyl

  • Automatic transmission

We own a 2000 Buick Lesabre. It was given to us by my father in-law who purchased it brand new in 2000. Both of us have always had the car serviced at Buick dealerships for all maintenance including oil changes. We have had several electrical failures, fuel injector problems and now the transmission went out with only 45,000 miles. My husband was driving to the office and the car all of a sudden slowed down and then came to a stop. He described it as someone shifting the car to first gear from fourth. However, the car is an automatic. Luckily, there was no one immediately behind him so he didn't get hit.

Vehicle was taken to dealer for fuel pressure regulator recall 04V090000 repairs. Dealer noticed antifreeze was leaking into the fuel injection system, and needed to be repaired. If the correction was not made it would ruin the engine.

  • Automatic transmission

Fuel tank and sending lines need to be replaced due to O-rings improperly fitted on fuel pump. In July 2000, vehicle was making a knocking noise when turning or going over a bump. Front/rear transmission mounts were defective components. Dealership put a sealer on this, but it failed to correct defect. The dealer had replaced motor, transmission mounts, power steering lines, gasket to catalytic convertor and switch for heated seat.
