CarComplaints.com Seal Of This Might Hurt

CarComplaints.com Notes: Buying the first model year of any vehicle is rarely a good idea. You become a guinea pig for the automaker and they are really not nice to guinea pigs.

The 2008 Enclave has a wide enough range of problems to issue a warning. There's transmission failure under 90k miles, new power steering units costing over $1,300, and enough engine complaints to NHTSA to scare anyone away.

Enclave 6-cyl

  • 80,000 miles


My two children and I were traveling on a highly elevated ramp between major highways in san antonio (281 and 1604) when my car no longer would move into a higher gear and suddenly stalled at its current speed. The engine roared, but the car would not go faster. The traffic behind me almost hit me, as I unexpectedly was not increasing speed as one would typically do entering a highway. It was extremely frightening to all three of us (especially my 9 year old) and required our exiting the highway immediately. The problem continued, and we immediately took the car into the dealership service center. The technician was able to determine the problem quickly, because it has been a frequent repair. The "wave plate" failure led to the failed transmission with additional engine problems. The bill exceeds $6000. Both the near accident and cost have been highly stressful. We want GM to address this "wave plate /transmission" issue before more people almost get hurt. The forums for GM vehicles containing this part have dozens of complaints already.

We brought this car from landers Ford collierville in 19apr13 and I have had to get the brakes redone, and a valve with the air conditioner fixed. But we went to sunrise GMC on 28jun13 and they advised us that we need a brand new transmission in the car due to a crack in some part of the transmission. I haven't had the car that long and now it needs a new transmission. Landers Ford knew that car had transmission problems. GMC advised us that this is a problem that happens in the Buick Enclaves and the arcadias. So if you know that this car had these problems, then why haven't a recalled been done on the cars. We did research this past week and everyone complains about the transmission. We also called GMC and they advised me that since I brought the car from a Ford dealership and not GMC that they can not replace the transmission. But they can give us 70/30 we pay 70 percent of the repairs which I can not afford. They advised us that the car came off the line in 2007 and that is why the car is 10 months out of warranty.

Enclave 6-cyl

  • 54,236 miles
My 2008 Buick Enclave only has 54000 miles on it and the transmission had to be replaced. The rpms would race up but the car would not move. The air conditioner also quit working at 39,000 miles but I waited until this breakdown to fix it because it was the beginning of the cool season. The high pressure line to the condenser and evaporator had to be replaced.

As I begin to accelerate the RPM's would go to 4 but my speed would only be 25mph. This has happened several times. When I pull over, turn the car off, start it again, then it runs like it should. I contacted the dealer and they said I needed a new transmission which will cost $4000. I have researched this problem and it seems that many people have had this problem but so far no recall. I have read that a part in the transmission is not properly hear treated which is the cause of the transmission problems.
