2010 Buick Enclave Engine problems

I am filing this safety complaint regarding a sudden and dangerous engine failure in a 2010 Buick Enclave CXL purchased from Frankfort Car Outlet on 8/25/2025. On 10/25/2025, while driving on the expressway, the engine suddenly began knocking, lost power, and stalled. This created a serious safety risk to myself and other drivers. The failure occurred only 60 days after purchase and approximately 2,000 miles later, suggesting a pre-existing internal defect that the dealership did not disclose. The dealership has...

The engine and fuel pump system failed while driving the vehicle. It is available upon request to inspect. I just towed it to the shop today on 10/22/25 to get a full inspection. My sister and I were put at risk while driving towards a hill in San Francisco. It was on a busy main road when suddenly the vehicle began to jerk and thud back and forth. While I pushed the gas pedal, I began to question why the vehicle was suddenly reacting this way. In efforts to pull over to the side, a huge smoke fog began to come out...

The engine was built with the same components as the 2008/2009 models and they have been recalled, the oil drains out of the engine rapidly and causes engine to seize and had to be replaced.

Car was running just fine had its oil changed new tires added and it just stopped running. Got it checked with a car technician and he stated it's the engine.

While driving down the road, the locks on the doors will suddenly lock, unlock, lock and unlock. After that the engine slows way down losing power, then it will be okay to give it more gas and it speeds up. The last couple of times this happened, the car lost all power and stahled.

Timing belt chain

The contact owns a 2010 Buick Enclave. The contact stated that after entering the vehicle, there was a knocking noise coming from the vehicle prior to starting the engine. After starting the vehicle, the noise became louder. While operating the vehicle, the check engine warning light remained illuminated and a humming noise was present. The vehicle was taken to the local mechanic who indicated that the transmission gear was faulty. The vehicle was serviced however, the failure persisted. No further information was...

I was driving my vehicle when it suddenly stalled and would not start, I had it towed to a mechanic and was advised it needed an engine, this was a known problem with the 2008, 2009, 2010 buick enclaves, because of the oil pump draining the engine of oil it seized the engine. I called gm and asked why they haven't recalled the 2010 along with 2008, and 2009 models with the same engine and issue. They said its been acknowledged but there is no future date if or when the 2010 buick enclave would be recalled for the...

The 2010 buick enclave has been well kept. I had just purchased it and only drove it for 2 months. I was driving on the freeway at 70miles per hour then the check engine light came on and the car lost power down to 40miles I had to pull off the freeway. Almost hit. The hole system shut down it wouldn't start at all had it towed to the dealer they said the timing chain jummped and locked up your motor it will be 10 thousand to fix I dont have that kind of money so now I m paying a loan on a car that does not work.

The throttle - position sensor is not working properly and engine started acting up while driving

2010 Buick enclave with 116,164 miles, just over 10,00 per year, engine developed a spun rod bearing and quit while driving. Steering lost power and engine stopped. I had to push it backwards to get out of an intersection. I had just started a right turn. 22 Month earlier the timing chain stretched on the vehicle costing $2000 in repairs. Oil was changed every 5000 or less miles and used mobile 1 synthetic oil the entire time. This and owners of earlier model years report this same problem from this vehicle. A well maintained vehicle should not have these two problems which points to some failure in design or manufacture. Vehicle is now junk.

The car shut off while I was driving it, I was starting to go from sitting at a red light and it just shut itself off! I've just purchased this car and already it's a hunk of junk. Also the amount of electrical problems caused by water entering the motor compartment is ridiculous and should be a recall as it's just a bad design. The ac fan motor located above the passenger floor fills with water and ruins the motor. The car shut off today because of shoddy soldering.

2010 Buick enclave was driving at approximately 50mph, engine stuttered, lost power, and would not accelerate. Pulled over and engine would not restart. Towed to local repair shop and found the engine had blown, gears blew apart, timing chain shot. Full engine replacement costing almost $7,000. Mileage was 178,222. Additional issues to include rear suspension parts, brakes, rotors, wheel bearings (twice) due to defective parts. Rear lateral links both upper and lower (twice due to defective parts). Car still does...

I am writing because we purchased a 2010 buick enclave in 2018. Immediately after purchasing I noticed issues with the vehicle and it had to be serviced twice within a couple weeks of having it. At the time the service dept. Could not diagnose the issue and blamed it on my accidentally touching the manual shift on the shaft. I knew I was not doing this. I have video of the car doing this weird acceleration and all during the last couple of years but [[redacted]] kept saying the vehicle was fine. Well, I was...

Well what happened was the vehicle dead stopped in the middle of traffic. This may not seem unusual, but this particular vehicle has been reported for the same issue, p0008 which is a stretched timing chain issue. This issue seems to be common with the 3.6L vvt engine that is shared across all models. My wife and child were in the vehicle at the time and were about to be hit by on coming traffic. Luckily, the vehicle coming toward them was able to get out of the way. The vehicle blocked traffic for several hours....

Timing chain failed in august 2017 at 87k miles. Over $4,000. Failed again in january of 2020 at 120k miles. Dealer only charging $400-500 due to my insistence and my desire to give them a poor review if they did not honor the repair.

Tl* the contact owns a 2010 buick enclave. While driving various speeds, the check engine warning indicator illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the timing chain needed to be replaced. The vehicle was not repaired and the failure recurred multiple times. John paul's buick gmc (3615 s 108th st, greenfield, wi 53228, (414) 482-6246) was contacted and stated that the vin was not included in a recall. The manufacturer was made aware of the failure and provided case number: 9-5585597823. The failure mileage was approximately 114,753.

Tl* the contact owns a 2010 buick enclave. The contact stated that there was a noise coming from the engine and the check engine indicator flashed. Studebaker buick gmc (3200 e main st, richmond, in 47374, (765) 962-0505) diagnosed that the timing chain was being stretched and needed to be replaced. The dealer quoted a repair cost of $2,000 and stated that they would call back with the final estimate. The manufacturer had not been contacted. The vehicle was not repaired. The failure mileage was 90,800.

The air conditioner hose was melted where it touches another hose, there was an acadia and a traverse that had the same problem. When I called buick to see if there was a recall, I was told only yukon had the recall. I have a problem with this, they are basically the same. They know these hoses run too hot not to be separated or at least insulated. The part costs an insane $861 dollars. All of these vehicles need to be recalled or corrected.

Today I was driving to work, as I pulled into the driveway of work ticking noise started and then car died right on a hill blocking travel, it would not restart, so I had it towed to my mechanic who advised engine blown do to timing belt wear...All my oil was sucked into engine (just had an oil change 2 mths ago) and blew the motor! This is a known problem with this year, make, model of buick, why is no one doing anything about a recall! I can't afford a new engine, nor a new car, I just purchased this used at...

The initial complaint was the check engine light and a repair was made that didnt fix the problem. The light came back on while driving and it was the timing chain and it needed to be replaced. The vehicle only had 47,000 miles on it.

When driving the traction control light comes on then I get a signal that my engine power is reduced. The speed drops drastically on the highway. Indicators say system stabilization.

Check engine light came on, originally read the codes as cylinder misfire 1,3,5. Timing chain inside the engine is stretched and means a very costly repair at 145k miles. Very common problem with these.

Gets the about timing chain. A lot of people talks about how timing chain goes out. . Think if gm had a lot of calls about this engine they need to fix. If I knew this I would have not buy it
