I had about $1700 worth of work done to the underneath of my vehicle... the lights such as service engine soon and ABS keep coming on... I had to put my brakes on and the anti lock brakes came on and I tried to press on the gas to go and it cut the power drastically on me little to none but if I lift my foot back up and I try to start agian it allows me to drive but then if I need to go up a hill or pass someone it loses the power when I put the gas pedal more than a 3rd of the way down. And it will not stop doing this.. I am extremely concerned as no mechanic seems to know how to fix this and I live on a fixed income and need my car to get around.

I purchased this car on June 23 and the next day it wouldn't start took it back to the dealership and they replaced the battery and the alternator said it was fixed but several hours later the car wouldnt start again took it back the next day and they said it was the air conditioner running while the car was off draining the battery so they took the fuse out and said they would fix it the next day but when I called to take my car to them I got no answer from them. Three days later the car overheated and I got it completely checked by a different mechanic to see why my car is running hot and he gave me a list of problems every head gasket is blown out and the motor is gone. He said that there was a recall a few years back on these types of Buick cars for the coolant and the wrong coolant was placed in the car and it messed up all head gaskets I immediately called the dealership but again no response I called the bank because I still have a 30 day tag and only had the car for two weeks but again no response I called Buick and spoke with someone to ask about the coolant recall and he said he would call me back in a hour and again no response. I asked for a carfax report and the dealership said they didn't have one but gave the couple behind me a carfax for their car the brakes and rotors are completely gone I cannot stop with my brakes I just have to coast so I want hit anyone this car will stall out on me without any warning. There has been no action taken from the bank or the dealership on how we can fix this problem they have all been ignoring and not responding to my calls texts or anything.

I parked my car in a lot. 2 hours later, I went to start it and it wouldn't even turn over. Someone gave me a jump start and it started immediately. A few hours later, same thing. Nix morning however, it started fine. Battery was tested and works normal. Replaced starter and cylanoid. Same problem and nothing changed. I decided to check the fuses. All of them ok. I found that if I remove one of the fuses and use a paper clip in 2 of the 4 openings, it starts the car in the on position. Security light comes on too.

The fuel line runmig from the engine to the fuel filter got a slow leak in it, filled the inside of the SUV with fumes and we had to pull over to air out the car then the fuel line split and fell off and gas spilled out and overcome the inside of the car with fumes. When repaired immediately, the mechanic determined the line accumulated excessive moisture and heat and caused it to break when it got hot several times.

I have a 2004 Buick Rendezvous and after running it, it does not always restart. It has also stalled at intersections when idling. No one can pin point a specific problem but after it sits awhile it restarts. Sometimes I have to sit for an hour to get my car started. A GM mechanic said there was a recall on a fuse, but there was not change made to the fuses so the issue was not corrected. Others have said it was the fuel pump, but then others say if it is the fuel pump it would have gone completely bad by now. This has been going on since 2008 when I bought the car used from a dealer.

Rear differential /torque tube defect. Vehicle taken to GM dealership to check whining, roaring and clunking noise. Garage indicated no problem with vehicle. Noises continued and got worse. Vehicle taken back to garage several times to no avail. Finally vehicle was taken to another garage to determine problem. Problem found and both GM dealership garage and the certified garage that fixed the problem indicated a defect in the rear differential with potential of locking up wheels while driving, causing the wheels to skid with the potential of causing an accident.
