Engine light came on and took into dealership for a diagnosis of issue. Was told that the timing chain had stretched and needed replaced with a cost estimate of $3000. This is the 2nd time that this has happened, the first being at 48K miles, and now at 95K miles. When the repair was being made, was told that the crank shaft was warped and had frayed the engine internally - caused by the bad timing chain and I now needed a new engine. Contacted Buick, but they would not do anything about it. Buick has known about this issue for years, and yet refuses to back their product or help their customers. Once the engine was replaced, I now have a loud power steering 'whine' and was told that the power steering pump needs replaced - another known issue by Buick. Just incredible.

I have owned my Buick Enclave less than 2 years & I am already having to put another timing chain in it! I talked to GM the first time but they wouldn't do anything about it but told me this is the same issue the 09S were having. If the next year up is having rhe the same issues why wouldn't they recall this as well its very expensive to have fixed every 10 months!!!!! the first time I was driving off the exit ramp of the highway when the vechile randomly quit with my 3 kids in the car it was the middle of winter in Michigan & the tow truck didn't get there till almost 2am couldn't get the heat on or anything! this second tine I heard a rattling in the engine so I took it in & its the same issue & although I have a 12 month warranty on the parts & its only been 10 months Buick is refusing to replace the parts so again its coming out of my pocket!

My 2010 Buick Enclave with less than 85000 miles had a catatstrophic engline failure on highway 895 in baltimore, md on 8/22/2017. We were traveling about 60 miles per hour when this happened. There was a loud noise followed by billows of white smoke and the car stopped. We had a tow truck pick it up and the service attendant at the repair place said there is a fist size hole in the engine block. This car has been well maintained and so it is bad that the engine failed. Since I live an hour and half away we haven't had a chance to take any photos.

My 2010 Buick blew a puff of white smoke and then lost power on a busy street with my wife and kids in the car. Luckily my wife managed to get it pulled off the side of the road without being hit by other cars. A GM mechanic replaced one injector at $510 and said we were good to go. The check engine light came on 2 days later and that code showed the timing chain. Now, the Buick dealership wants $3000 to put a new timing chain in it. $3000 is only if there is nothing else wrong!!! why is this problem not a manufacture recall?!

- Barker, NY, USA

Vehicle hesitates when accelerating and my engine light came on, had it checked and it is a stretched out timing chain. Very scary to drive. Vehicle is manufactured in 07/09 according to the manf. Sticker on the door. Repairs are very costly and there is an extended power train warranty on the 2009"S.

Check engine light came on at 71000 miles. After two separate diagnostic checks at two different locations, both matched with diagnosis of issue with a bad timing chain. Vehicle is tagged as 2010 even though label inside car shows as being actually having been manufactured in 09/2009. Discussions with dealership where purchased and Buick themselves led to no action in terms of warranty/recall/special conditions coverage - even though this was a known issue on the Enclaves produced between 2007-2009. Initial estimates for the work, including labor exceeding $3000. NHTSA 10052863 shows that 2008-2012 Buick Enclaves and the availability of 3 service kits for high feature V6 engine applications. Further, it shows that these kits should be used on vehicles covered under the terms of the any warranty or special coverage terms. Yet for some reason, the 2010 hasn't been assigned 'special coverage' terms.

The service engine soon light illuminated while the vehicle was in motion. The vehicle was taken to the dealership and a P0008 (timing chain) code was diagnosed. After reading numerous cases online about catastrophic engine failure, the car was parked and I began dealing with Buick customer service (crc) and later with the executive referral group. The Buick brand quality manager said that the problem was "fixed" for the 2010 model year and that's why the GM special policy #11340C was limited to 2007-2009 model years.they refused any assistance in fixing the engine. However, the GM bulletin sb-10052863-6133 specifies 2007-2012 model years. The technician that performed the repairs (at my expense) said that the failure was identical to the 2007-2009 vehicles. They even had parts on hand- which shows the extent of the problem. As of this writing, there are 65 other complaints in this database of this problem on the Enclave and it's siblings. The NHTSA id 10052863 lists 75 associated products. Clearly, there are many more 2010 failures if every product is evaluated. This is a safety defect that should have a campaign issued. Loss of engine power and the resulting loss of steering and brake assist is clearly a danger to the passengers and all surrounding people and property. Previous campaigns, such as the GM ignition switch issue, show that loss of steering and brake assist due to loss of engine power is a safety issue. A service engine soon light does not convey the potential gravity of the situation.

The contact owns a 2010 Buick Enclave. While driving 40 mph, the motor failed without warning. The contact stated that the timing chain failed and was replaced; however, the failure recurred. The manufacturer was made aware of the failure. The failure mileage was 110,000. The VIN was not available.

Without any warning signals our timing chain stretched and slipped on our 2010 Buick Enclave. It caused significant damage to the engine. The engine completely died while in motion, stopping the vehicle from movement in the middle of the road. I was luckily on a country dirt road without much traffic, otherwise this could have gone very bad on the highway or interstate. The 2007- 2009 Buick Enclave has this same know issue with a recall, and from what I have been told by our mechanic the parts used in the 2010's are the same. It is irritating that there has not been a recall with the 2010 and later, I've seen several reports of the 2010 having the same issues. I have not received my car back from the repair shop, but can provide a invoice once one is available to me.

When accelerating to merge onto highways, when accelerating to overtake vehicles and when depressing the gas pedal to climb steeper hills the car engine would not respond. This was an intermittent issue as only occurred occasionally. However, on at least 2 occasions there were near crashes of vehicles into the rear of the vehicle. One time while merging onto a highway and depressing the accelerator the engine would not increase speed and stayed at 45mph. A Transport truck in the right hand lane closed distance and had to brake as they could not move to the centre lane and I was unable to get to shoulder as I still thought the engine would respond. I eased off the gas and then accelerated again which then kicked in the engine. Another time a similar incident happened while I was climbing a steeper grade on the highway. The vehicle would not respond and keep speed and started to lose speed and I moved to the right hand lane. I could not go to the shoulder as there was a guard rail along an escarpment. Again, a Transport truck came up right behind me anticipating I would be keeping speed. Over the last few months this happened to my wife and I a couple times a week and had taken this into a garage to be checked out. At that time there were no indicator lights on or codes and the garage found nothing. About 3 weeks ago the engine check light came on and we took it to the garage where they advised us to take to a dealer as it was a timing chain problem. Upon diagnosis the dealer said it was a stretched timing chain. I did some research on this issue and what I found and what really bothers me is that GM was aware of this problem and actually issued a tsb for 2009 models. My car was built in model switch over time as a 2010 model in August 2009 but with the same parts and timing chain. The company obviously knew that the vehicles could have issues and failed to notify.

Check engine light came on while driving on the interstate highway, the vehicle lost power, reducing the speed to 35 mph in a 70 mph interstate. The vehicle cut off and would not restart. It was towed to the repair shop which 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. A major issue when you are traveling at 70 mph and suddenly your engine loses power and you find yourself doing only 35mph with no power and then it stops suddenly.

I was driving at 75 mph and my engine shut off; car began to slow, fuel dropped, power steering went out, brakes didn't work. I was able to, thankfully, get to the side of the road safely and use the rumble strips to slow me down. I turned the car off and 5 min. Later turned it on and was able to drive to a safe location. This is a common issue and all of these conditions are related to the "limited warranty protection" that GM issued Nov. 2015 (14582). This is a safety hazard. My car experienced all the other condition, malfunction indicator light came on multiple times ( may, Sept), was issued a letter in Nov. 2015 and then this occurred in Jan. 2016. Stipulation for this to be covered, under 120K miles of 10 years whichever first. My car experienced initial troubles at 110K in may and this potential fatal incident at 125. Arguing with GM over this. Should be a recall, not a limited warranty. Seems to be an unethical company. Does it take death to make this right? this has occurred countlesss times- check the internet, 100S of customers have reported this. Does this have to be another Toyota incident for GM to recognize this is a recall not a limited warranty! I have all paperwork showing the issues except dealer states since they can't replicate, they need the check engine light on and the car to be under 120K to determine if they should pay. GM is unethical!!!

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. However, it appears that this is a recurring problem with the vehicle.
