2010 Buick Enclave transmission problems

Filed Sep 3, 2025 · Suspension, Transmission · FL

I purchased a 2010 Buick Enclave from a dealer who did not disclose any major issues with the vehicle. After purchase, I began experiencing significant problems while driving, including difficulty shifting, loss of power, and unstable handling. Concerned for my safety, I took the Buick to a mechanic for inspection. The mechanic verified that: •The wrong transmission had been installed in the vehicle, causing unsafe shifting and performance issues. •The driveshaft was malfunctioning, which affects the stability and control of the SUV. •No warning or check engine lights were on •CV axel bolts were zip tied closed Because of these defects, the mechanic told me the vehicle is not safe to drive. These problems were never disclosed to me at the time of sale, and I would not have purchased the vehicle had I known.

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.

Engine light is coming on due to issue with timing chain. My mechanic said gm issued a service bulletin and gm offered extended warranty coverage to fix the problem for model year 2009 but not 2010 (which is my model year). It was a known problem and gm refuses to cover the repair of the timing chain replacement.

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 not ride properly after second replacement of parts and 4 all wheel alignments. Car sways terribly and rocks especially during higher winds. Very hard to keep on the road and dangerous.

Vehicle losses power, engine light came on, codes p0008, p0017, p0009- took it to shop and they said the oil was 3 qts low. I just had it changed within 60 days. They changed the oils and cleared the codes which were showing. I also had transmission fluid changes and a new front left transaxle installed. Wife drive the vehicle home, which is within 3 miles of shop. Engine came back on with the same three codes given above. Caleed back to shop next day, they said engine would have to be pulled and the chart said about a 21 hours job (they charge $68/hr). And said it would be about $2500 to fix. I see many posts online with this vehicle concerning this same issue. There should have been some type of recall on the timing chains/belts in these cars and like models.

In 2017@75,477 miles my car lost power on the highway, could not get it to go over 40mph. Drove to dealer & turned out to be timing chain which is a known issue in my type of car. Dealer repaired car at warranty price, even though my warranty had run out & took 40% off since I had been such a great customer. They had some kind of incentive money available.fast forward to april 2019 @ 95,000 mikes, car is losing power again on highway especially when merging, must floor gas pedal to get car to go, engine light on intermittently at first, but now on permanently, timing chain code (p0008) comes up & dealer says it will be an estimated cost of $2500 to repair, must pull engine again. Timing chain repair from 2017 only under warranty for 1 year or 12,000. I went 2 years & 20,000 since repair. Dealer only willing to discount repair needed now @ 25%. This is a known issue with my car especially the 2008, 2009 & 2010 models. There are tons of on-line complaints about timing chains in my type car & there should have been some type of recall on the timing chains/belts in these cars. It is a known problem. Not safe when driving on highway & problem can occur at any time without warning.you lose power & can get stuck in middle of nowhere. Unsafe!
