When in reverse, the vehicle will still roll forward on a decline and when drive, it rolls backwards when on an incline. It acts as a stick shift. I was going up an incline coming out of a parking lot and stopped. When I took my foot off of the brake to go, the car rolled backwards and almost hit the car behind me. I pulled into my driveway and took my foot off of the brake and it rolled two lengths before I put on the brake to stop it from going in the street. While reversing into my inclined driveway, if I don't keep my foot on the gas to control momentum or it will roll forward.

Driving on interstate 75 North of cincinnati oh in bumper to bumper traffic on 7-13-15 in left lane when buzzer sounded, traction control light came on and engine lost power. Trying to get to shoulder was a bad experience as traffic was having one hell of a time trying to cope with a car that suddenly wasn't moving. How a bad accident didn't happen, I just say it was good luck! we really like our Buick Enclave and would like to keep it. I have a code reader and no code was revealed. I pushed the traction control button several times and reentered traffic and the car ran fine for the next two hours to home......

I had taken the car to Buick dealer for an oil change. I asked them to check if they saw a possible oil leak because I saw a few spots in the garage. They said there was a leak from a rubber bearing and the cost to fix that was 2700. Tool the car sears to have them double check. Sears said there was not leak. There was residual oil from oil change. This was on 06/20. Checked every day after that to see if the oil leaked again and it did not. On 06/28, while coming home with my kids, hear sudden noise, and in a few seconds smoke coming out from left front side of the car...lot of smoke. Got the kids and dog out safely. Tried to turn off the car...I had the key out but the car was still on. It just would not turn off. Tried taking it our of the garage and the steering would not turn. Somehow got the car on the curb and after trying a few time, the car did turn off. Noticed all the coolant had flushed on the floor. Got it towed to the dealer. Dealer said power steering gear and power steering pump burned and needs replacement. Also said it was because of a minor oil leak that was under the engine that caused it. Coolant flushing was covered and GM will pay for the fix but I will need to pay 2500 for the steering gear and pump replacement. This could have been a disaster and life threatening if it had happened at high speed. GM least concerned about it and not supportive or standing behind their cars. I have only 36K miles on it and would not have expected something like this. I read on some forums where a lot of people have had similar issues. For the safety of other Buick Enclave holders, I please request you to have Buick act on this and send a recall.

Enclave 6-cyl

  • 69,952 miles


My dealership identified a significant problem with the power steering gear on my vehicle that constituted a significant safety issue. Had it not been caught, my power steering inevitable would have failed while driving and resulted in a crash. I was also advised by the dealer and have learned through research that this is a very common problem affecting Buick Enclaves and other similar GM SUVS and crossovers. The repair work to correct this manufacturer defect is over $1500 and conveniently not covered by warranty. This is a significant and unacceptable issue and should result in a recall of all affected vehicles and reimbursement of repair costs to affected owners.

No sound, just quit when I tried to increase speed. Onto highway I.had to pull over and went slowly into garage. The car has complete transmission failure, bad bearing on transfer case shaft, which is leading to 7 thousand dollars in repairs. I take great care of my cars and am very disappointed in the performance of this vehicle. I am surprised there are no recalls. Why would a transmission fail at this mileage? I am looking at another car manufacturer for my next vehicle. I have always purchased GM products.

In August of 2014, around 60K miles, I noticed a moan when I steered as well as a "knock" that I had heard previously and taken into the dealership under warranty (they said it was a tire rod; clearly it was not). I was aware the moan may be my power steering pump, so I brought it in for diagnostic appointment to a local repair shop. Not only did I find my power steering pump needed replacement, but that was the cause and effect of a much large issue- my steering rack was loose, and was disengaging from the mount, which in turn, caused the corruption of my power steering pump. I was told it was worsening very quickly and if I lost my steering rack from the mount, I could lose steering, which could result in a crash. I was informed this type of repair is highly unusual for a car this new, with no accident history, and otherwise in excellent condition, and is likely an "engineering issue." I am appalled at not only the price of these repairs which I paid out of pocket ($1,968.51), but after some research, how common this particular problem is with 2008 & 2009 Buick Enclaves, especially around 60K miles. The mileage on my vehicle now is 65,342.

Enclave 6-cyl

  • 52,000 miles
Purchased a 2009 Buick Enclave in September 2014 with 49013, I drove it to Georgia October and noticed on the trip that the vehicle would roll back while in drive on an incline, both forward while in reverse and backward while in drive. After returning I scheduled an appointment with my dealer about the problem and was informed that the roll back was normal, I have driven many vehicles with automatic transmissions and have never encountered this problem. I checked on line and found many complaints about this from 2009 to 2011, I believe they corrected the problem in 2012. I feel this is a major safety problem and should be corrected before someone gets hurt or killed. Are they going to let this safety hazard continue like they let the ignition switch problem with General Motors vehicles continue until people were injured and killed. I have read that if they fix the problem it would increase the fuel consumption, I would rather have a safe automobile that get a little less miles per gallon then an unsafe car that could end up killing someone. This problem should be conveyed to people who are looking to purchase a Buick Enclave with this defect so they can decide if they want to drive a unsafe vehicle. I believe most of these problems began right after the bailouts by the government, could it be General Motors decided to cut back on safety features on its vehicles in order to regain their profitability in the car market and make them look good.

Enclave 6-cyl

  • 67,878 miles
In the past I had jerking or slipping of transmission at approximately 40 miles an hour, or the engine was having a coil miss fire. I had 3 new coils installed by dealer under warranty with similar problems before. Took to dealer and they could not determine if transmission was slipping or engine miss firing, but no code on miss firing engine. Slipping or hesitating of transmission is more likely but can not determine since does not act the same consistently. Steering noise started in the winter approximately November 2013, but off and on since; steering seems a little stiff but not failing yet like so many other complaints I have read about here. I was charged $342.81 for dirty throttle body and oil in the air dust tube which might cause misfire, they cleaned and replaced bank 2 value cover and cleared codes, performed idle lean reset. This did not fix problem on 05/19/2014. I returned on 06/10/14 and left car till 06/11/14 the dealer let me use a loaner over night. The dealer said stumble/misfire at times was not acting up enough to diagnose. I had the cars automatic transmission flush service on 02/26/14 and there was no problem at that time. In the course of owning this vehicle I had 3 coils replaced with problems starting 01/05/10 one coil, second coil on 08/11/10. Third coil shortly thereafter, this is after complaining since 12/02/2009 about engine shudder. The misfire/stumble is still happening about 40 mph and sometimes around 20mph if you are slow going but not on a pull or accelerating. We love the car, but the problems are getting expensive and the worry of what else can go wrong is stressful. I did not mention the warranty repairs of water pump going out front motor mount failure, shift lever, airbags, seat belts, left out remote mirror failure, engine and transmission code updates. Dealer seem ok, so GM can not fix or will not due to cost.

While stopping for a traffic signal on a slight incline the vehicle began to roll backward. The engine would not hold even for the amount of time to move my foot onto the brake. Vehicle rolled backwards approximately 1-2 feet in process due to weight of auto and inability for drive train to retain the original position. Upon investigation I found this problem exists and will not be addressed by the manufacturer.

Enclave 6-cyl

  • 57,000 miles
I took my car in to be fixed again. I needed the running lights and a hesitation in the car fixed. So they fixed the problems, but when they went to test drive it the power steering failed. Now the power steering needs to be replaced. It seems this car is needs to be fixed all the time. I have had a lot of cars and this is the most I have ever had problems with a car. It really scares me that this can be fixed but will most likely fail again due to the problems with GM's steering.
