2008 Buick Enclave engine NHTSA complaints: Vehicle Speed Control

NHTSA — Vehicle Speed Control Problems

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.

The contact owns a 2008 Buick Enclave. The contact stated that the stability traction control warning light continuously illuminated. The contact mentioned that every time the failure recurred, the vehicle would drastically decelerate making it extremely difficult to operate. The contact had to turn the vehicle off and on in order to reset the computer. The vehicle was able to restart each time but the failure was getting progressively worse. The vehicle was to be taken to a dealer to inspect and diagnose the failure. Also, the contact received a recall notice for NHTSA campaign number: 15V415000 (structure) and was waiting on the permanent remedy and part to repair the vehicle. The manufacturer was contacted and could not provide an estimated date for when the vehicle would receive the recall repair. The approximate failure mileage was 150,000.

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.

  • 1,039,000 miles
We were driving our Enclave on the highway (route 1 near stafford, va) when it felt like it was suddenly not shifting gears correctly and quickly thereafter lost power beyond 30 miles per hour. We drove into a parking lot. We called the nearest Buick dealership/repair shop (route 1 Buick in woodbridge, va) and told them of issue. They said it sounds like transmission and the wave plate is a "known Enclave problem." They said to have it towed to them and they may be able to assist us with cost as it's close to within powertrain warranty. We had it towed to route 1 Buick. They diagnosed and found all transmission and wave plate codes. They said it was a "known problem" and so they called Buick GM service manager. Route 1 Buick called us back to say GM would not assist us as we were outside warranty by 3,000 miles and had no previous issues with transmission (I have found several other transmission and power loss complaints I and the previous owners made on this exact vehicle in my research into this...I have kept all records!). route 1 said that our cost would start at $3,800 with no guarantee they wouldn't find other issues needing to be addressed. The said lucky for us, our vehicle had an open recall on a side air bag issue they could fix. As we realized we must pay out-of-pocket and couldn't afford $3,800, we paid them the $120 for diagnosis and towed it (at our expense) to dun-rite transmission in fredericksburg, va. Dun-rite found it had a broken wave plate. They rebuilt transmission for $2,800. Unfortunately, the stabilitrak, traction control, and air bag sensors are all also going off and car has had 2 other instances of losing power when driving since. We purchased the certified GM car Nov 2012. My car payment is $462. Per mo. Since that time we have spent an additional $6,095 on repairs and maintenance. Our average monthly expenses are therefore $801. Help us!

Enclave 6-cyl

  • 50,625 miles


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!!

Enclave 6-cyl

  • 89,958 miles
I started from park and shifted to drive. As soon as I gently stepped on the gas to accelerate there was a jolt and loud noise. It shifted rough basically. The check engine light came on immediately. I stopped and looked under the car and hood for any signs of damage or leaking fluid and found none. I then decided to stop at the first auto part store I found to get the code read for the warning light. The codes read P0717, P0716, P0700, P0756. The tech told me that this indicated one of three problems all dealing with the transmission. So I decided to drive home and figure out what to do. As I started to drive it failed to shift from first gear. So I ended up driving slow due to the car being in first gear. Then suddenly the car acted as if it was in neutral, not allowing me to go forward or reverse. So I coasted to a stop and had the vehicle get pushed the remaining block. The shop tells me that it is some kind of wave plate and requires a new transmission at close to an estimated $5000. I just bought this car because I recently had a baby and have another child. I work for the military and can't afford this kind of repair 8 months after I had purchased it. Since this problem I have done some research and there are hundreds of people with the same problem. Which leads me to my question, when is enough" how many does it take to have a recall" my family are now down to one vehicle until I can figure out a way to pay for this repair.

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.

I was driving and upon trying to press the brake the car jolted almost causing me to hit another car. The car said traction control off. I cautiously drove home with the same issue occurring but realize that the traction control kept going on and off constantly. When I read online about this issue I realized a lot of people with the same model and year are dealing with this issue no matter the mileage.

Enclave 6-cyl

  • 115,700 miles
An audible "sloshing" sound had been detected for some time but origin/exact location of sound not identified. When parking car after driving in thunderstorm all warning systems lights flashed, radio stopped, and radio and turn signals failed. Car did restart after sitting for brief period of time and systems worked except for xm radio. Took vehicle to Buick dealer who diagnosed problem as leaking windshield, removed and reinserted fuse for xm radio, and referred to company who had replaced windshield several months before. Windshield company determined windshield not leaking, but drained water from motor blower and blew out drainage tubes. One week later, water started to pour on to passenger floor mat. Warning lights for all systems flashed and electrical system shut down and care would not restart for a few minutes (and could not connect to onstar). When car restarted, lights did work, but turn signal indicators inside car did not, nor did speedometer, power windows, passenger airbag, etc. Had to drive 60 miles to dealership without these working. Paid to have "foam seal" replaced to prevent rain from entering car (the presumed source of problem). They also claimed to have drained water from motor blower housing cleared tubing. On the way home from repair, water again poured from area of motor blower onto passenger floor mat, and once again, electrical systems not working. Buick still does not know where water is coming from, [but believes that since electrical systems working fine...after sitting there for 24 hrs...everything is fine. Obviously it is not. I have seen numerous similar complaints online dating as far back as 3 years. I will add that this follows 2 years of dealing with stabilitrak...which is supposed to be a "safety" system but can be life threatening when the car suddenly reduces power in heavy traffic and/or no maintenance lane.

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.

  • 36,000 miles
If after within approximately 2-4 seconds after dropping my 2008 Buick Enclave into passing gear I need to perform an emergency stop, the vehicle continues to try to accelerate. It's as if the accelerator and brake are depressed at the same time. I took it to the dealer and they were able to experience the issue but when they checked with GM tech support the dealer was told a 2 or 3 second delay was normal and within specifications. This has happened approximately 5 times since I've had the car (late 2007) and has caused 2 near misses but no accidents.
