Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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.

Since I bought my truck I heard a weird noise from the steering wheel I thought well maybe because im not used to it because before I was driving an Nissan X-terra 2002. So im a women don't know anything about cars so I said it looks good it was from only one owner before so I think we are good. Plus I thought it's not like I'm paying $5,000 for a truck and it's a Buick it's consider luxury so I didn't think I was making a bad choice. Well the noise it's getting worse I barely made it to my house yesterday because the steering wheel didn't want to work anymore it was raining so hard im 9 months pregnant I made that investment doing a huge sacrifice so me and my child could be protected, feel confident that at the end of the day we are in good hands in that truck. Also when I bought this truck a month later the air bag service light was on I did a research it said that this truck had a recall for that so I took it to the Buick and they fix it. And now the engine light turns on every now and then. I mean I'm doing everything I should for this vehicle I change oil regularly and I pay for the synthetic oil because they said it was better for this type of brand cars that are luxury for our middle class people. And it's not like I travel in that vehicle I only use it to go to work, groceries, family and friends house honestly I don't use it to travel where I live is a small town so it's not like I have this truck all over the place if you see it's like new it's the cxl it has 2 sunroof, leather seats, dvd player I mean im in love with this truck but C'mon that's not safe for me and my baby.

After 66,000 miles of easy driving, our 2008 Buick Enclave has a broken wave plate and needs a new transmission! the transmission failure caused two separate dangerous driving situations, one of which could have been fatal. The first event occurred when stopped at an intersection to make a left turn. I had two children in the back seat. When the intersection cleared, I began to make the left turn, but the engine failed to accelerate and merely coasted into the lane of on-coming traffic. The left side of the vehicle and the 7-year-old child sitting there were left exposed to the threat of impact by fast-approaching traffic. After about 2 seconds, the engine accelerated and we were able to leave the intersection moments before on-coming traffic arrived. The second event occurred two days later. Traveling 45-50 mph on a local highway, the engine slipped gears and would not shift out of first gear. The check engine light came on. We returned home at slow speed. In the driveway, we put the car in park, then in drive and reverse. It barely moved in either direction. The next day, we were able to drive it to the nearby dealership. It shifted gears on the way, but the warning light stayed on. The dealership informed us that the wave plate is broken and that the transmission must be replaced. We tried contacting GM customer service but received nothing more than a recorded message asking us to hold on the line. We held for over one hour and received no customer service. A review of many website postings reveals a widespread failure of the Enclave wave plate and transmission, that GM is fully aware of it and has taken no steps to address it or to ensure of the safety of the thousands of Enclave owners and other drivers on the road. Failing any accountability by GM, we insist that NHTSA take action on this widespread safety hazard and issue a recall.

Engine lost power...on interstate 90 going 70mph....tried to accelerate and engine revved up but no power to the wheels....I was able to steer the car from the passing lane to right lane then on to shoulder of road and turned off the engine. Prior to this event the vehicle's transmission was shifting a great deal as has been towed to a Buick dealer in rochester, NY awaiting a call....from the internet readings expect the problem to be the wave plate and transmission to the tune of $4000....I plan to escalate this problem to the highest levels at GM as the failure was very scary being on the nys thruway driving at 70mph

Enclave 6-cyl

  • 57,000 miles
I was driving at approximately 55 mph when I felt my steering wheel go stiff and my RPM gauge dropped. I tried pulling over but had problems turning the wheel. That is when I realized my Enclave had completely shut off while I was driving. I was able to put it into neutral and hit the brakes to bring the vehicle to a stop where I then restarted it. That was 2 days ago. Today I went to start it for work and for the 3rd time in 2 months it would not start. I have already had the battery as well as the connections checked with no wrong findings. I have only had this car for 4 months! I called the dealership and they said that there is a 'service bulletin' posted in their repair shop because "many people" were experiencing the same problem but it was not a recall.

My husband, I, and our 3 young children were driving on I-94 at 70mph when our check engine light started flashing, the vehicle immediately starting shaking and riding extremely rough and the engine died. Fortunately we were in the right lane, and there was a wide shoulder for us to pull onto. We had the car towed to a GM dealership, who ran diagnostics and found that there were cylinder misfires on cylinders 1,3 &5. they ran further diagnostics and found that a valve spring broke & dropped into the cylinder. The piston hit the valve, knocked a hole in the piston, and pieces of the valve went through the engine. This vehicle was purchased 5 yrs and 9 months ago (9 months out of the warranty), but only halfway through the 100,000 mile warranty. We were given a GM customer service contact name ([xxx]) and number, but she will neither answer her phone, nor return our numerous messages! we purchased this vehicle brand new and have done all maintenance work on schedule, and have never had a problem with this "luxury" vehicle. We chose this vehicle for all of its safety features, as parents of 3 young children, safety is of our utmost concern. We certainly didn't feel safe 3 hours from home, traveling back from vacation, in the middle of wi completely stranded with a vehicle whose engine died within 5 seconds of the warning lights coming on. As inconvenient as it is that our vehicle is 3 hours from us, we are so thankful this didn't happen in downtown Chicago, where a dead vehicle on I-94 could have easily turned into a fatal collision.

Enclave 6-cyl

  • 78,000 miles
Driving through intersection roughly 35mph, transmission stalled and vehicle quit moving. Luckily all other vehicles stopped and no crash occurred. Vehicle had all seven seats full with passengers, 2 adults and 5 children. Vehicle had to pushed out of the way to side of road. Passengers (adults, children and babies) were stranded in snowy weather and had to be picked up by another vehicle. Vehicle has 78,000miles on it with no previous issues with transmission. Was told by mechanic that its the 35R wave clutch plate. There is a service bulletin on this vehicle and other models like it such as the acadia. Cost will be upwards of $3500 to replace and the vehicle barely has any miles on it! why has this problem not be taken care of...."??" it is a huge safety issue. Could have easily caused an accident and killed all seven passengers had we have gotten side swiped! this is a large SUV multi passenger vehicle...not a two seat car!!

While driving with my daughter, and dogs from the vet; the car began to slow down and eventually stop. I tried to restart and vehicle turn on lights, ac, radio came on however would not crank. Pedestrians pushed me out of harms way and into a parking lot. Towed to dealer immediately without inspection they said it is engine failure and I would be responsible for over 7000 worth of damage. The car had a full warranty and extended warranty which just recently ended. I am still making payments and had the vehicle less than 1 year.

This car has a whinning noise coming from the steering column that gets louder the more drive it. I have contacted the Buick care dept and they indicated it is a known problem but they will not fix it. They had me take my car to the Buick place where I purchased the vehicle and they come up with about $1900 to fix this and say that it is a known problem with the Buick steering that some housing is too close to the steering column and it creates the noise and steering problems and that Buick and everyone else is aware of it and that they should issue a recall but do not. In addition I have engine stalling problems where there is lack of power upon sudden acceleration. This happens frequently.

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.
