Check engine light came on. Repair shop identified it as timing chain stretched. On-line research shows that the timing chain has been an issue with Buick, and they extended the power train warranty to cover repairs for the 2008-2009 model. It appears that the same or similar problem is occurring with the 2010 model. The problem did not manifest itself until after the 5 year/100,000 m warranty expired. The dealership confirmed the problem was a stretched timing chain and replaced it. Gm provided some relief with a courtesy coverage of part of the cost. However, it appears that this is a recurring problem with the vehicle.

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.

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 delearship, 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 (lashawn) 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.

I was driving on a highway the check engine light came on approximately 25 seconds later the engine seized I was able to get to the shoulder of road but experience was life threatening. Gm has done nothing to help refuse to pay for anything even though I pay them 1 year ago to solve this problrm.

On July 12, 2012 while entering the interstate the check engine light and traction stability service light came on. The car would not accelerate or shift, I could not increase speed to merge into highway traffic, as I tried to merge the vehicle slowly increased speed, not normally accelerating. I eventually was able to get to 55 mph. The next time I drove the car it acted fine. Two days later while driving at 60 mph on the interstate without warning the check engine light, traction stability service warning light, the abs brake warning light all came on the brakes felt like mush, the car slowed in traffic, all while in the passing lane with traffic behind me. This created an extremely dangerous condition that could have easily resulted in serious injury or death. I eventually was able to move to the middle lane (3 lane roadway) and nursed the vehicle destination. When I started out again it acted fine w/check engine light and traction system warning light on then w/out warning while trying to enter the interstate again all gauges failed, ac shut off, cruise control power went off, the vehicle would not accelerate, would not shift, speed slowed from 30 to near 20, then systems started to turn back one at a time & was able to nurse the car home at 50 - 55 mph, it would not shift or accelerate correctly. Took vehicle to dealer,where purchased, they had the vehicle for 2 1/2 weeks called me stated "we can not get it to act up, come and pick up car" not repaired. I asked about codes in computer, I have a copy of these, they stated they were history codes not hard codes. When I asked about them forcing me to drive a dangerous vehicle, could cause serious injury or death, they said if it acts up to bring it back. Within 12 hrs the same events occurred as listed above. I drove it to them while all warning lights were on. They still have car it has not been repaired yet.

Vehicle 2009 Buick Enclave. Keeps turning on the light engine and at the dealership they keep telling me that is because I don't close the gas knob correctly. When the engine light turns on while im driving it gives me a message of power engine reduce and it reduce my speed and I can't continue driving. I've almost cause 2 accidents while im driving due to this issue. It will completely stop in certain times while im driving. Last incident 06/05/10. As well, my tire got flat around a month ago and I realized the dealership sold me the vehicle with no extra tire and emergency equipment to change my tire.
