Engine And Engine Cooling Problems of Buick Enclave - part 1

I came to a stop in the left turn lane at an intersection with a red light with the car in drive and my foot engaged on the brake to wait for the light to turn green. The car suddenly and completely died and all power was shut down. I was not able to engage the hazards. It was dark outside and I was afraid cars behind me would hit me. It was an incredibly dangerous situation with no warning. I exited the vehicle and got to the side of the road. The police arrived and were able to push the car to the side of the road as well. I opened the hood and checked the negative battery terminal and upon pulling the lever, the power came back on. We have an appointment at a gm dealership on Monday to fix the issue to ensure we are not put at risk again.

I am a [xxx] and owner of a 2018 Buick Enclave that suffered a catastrophic transmission failure which nearly killed me and my child. On Friday, [xxx], while driving westbound on [xxx] from edison, NJ to my home in easton, PA, my vehicle suddenly and without warning came to a complete halt in the fast lane. A driver tailgating me swerved at the last second to avoid impact. Moments later, when I tried to move again, the car lost all power and drifted helplessly across two lanes of speeding traffic, directly into the path of two tractor-trailers barreling down at highway speeds. This was the hottest day of the summer, and I was left in terror, fully aware that one wrong move would have ended our lives instantly. The fact that my child could have lost their only parent because of a mechanical defect is beyond unacceptable. The stress, fear, and trauma of this incident cannot be overstated—it was a near-fatal event that never should have happened. My mechanic has since confirmed the transmission is destroyed, with black metal fragments throughout—clear evidence of internal failure. Only two months earlier, in June 2024, the car passed inspection with no codes or signs of a problem. This was not wear and tear; it was a hidden, catastrophic defect. In December 2024, gm recalled more than 461,000 vehicles, including certain 2018 Enclave models, for transmission defects leading to rollaway and internal failure. Source: the lemon firm, 12/18/24 [xxx] ). My case mirrors the defect exactly, yet I never received recall notice. I demand gm confirm my VIN’s inclusion and cover the full cost of repair or replacement. I barely escaped a fatal crash. Gm must act immediately before lives are lost. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Wednesday August 6th 2025, I was coming home from work, the low engine compression and engine light came on the car was shaking and I lost power on a busy road, I had to pull it off the road quickly before I lost all power.

But the engine light stayed on after about 30 min. I shut the car off. The engine light went off after I shut the car off.

The front exhaust pipe bracket has broken. Upon investigation, this is an ongoing issue for 2018-2019, and 2021-2023 chevy traverse and Buick Enclave models, but not 2020. All of the models use the exhaust system and same bracket, and it should be included as a special coverage. In fact, the attached picture of my vehicle will show that it is an identical break to those pictures used in the previous bulletins. Any help is appreciated. Reference: n252503850, n242445280, n222385510, n212356540, and photo attached.

During a rainstorm water is entering the fuse box under the glove box and the carpet and padding underneath is soaking wet on the right front floor. When the fuse case was opened water started to drip out. The engine continues to run with the key off and the only way to stop it is to pull the ignition fuse under the hood. Unfortunately the battery died by morning and I could not get it charged for a few days. Now I have learned how to take the battery cover off which is located in the back of the car and remove the plastic covers under the mat so I can disconnect the battery so it doesn't run down. The rear wiper will not shut off now since this started. I am a 75 yr old widow and wonder how this problem has not been on a recall. It causes a very dangerous situation. I will try to see if I can get it into a Buick dealer this week and pray god it doesn't cost me an arm and leg to repair it. There are service bulletins on this problem and seems to be quite freqent yet I have not received any notifications from you. If this happens at night in a parking lot what am I to do? can the car catch on fire by not shutting off?.

The car shuts off at random when coming out of autostop, the car will disable power steering when coming out of autostop to make turns making it difficult to turn the steering wheel.

The vehicle's exhaust intermediate pipe mount has broken has caused damage in the intermediate pipe requiring both the be replaced.

A recall (n222385510) for 2021 Chevrolet traverse has been made however is addressing this on only the 2021 models, even though the same issue is applicable to other models. On the this forum, there are several complaints of this design flaw reported. Https://gmauthority. Com/blog/2023/06/gm-to-fix-2021-chevy-traverse-front-exhaust-pipe-issue/.

I took my car in for routine maintenance service and requested them to investigate a rattle noise when the car is started and when it idles. The vehicle was around 96k mile range. The repair center said it was the fuel injection system and it was normal. Fast forward to now, I have 111k miles, same rattle noise, and took my car back to shop for routine maintenance service and investigation into the rattle noise. It's the timing chain. Timing chain was stretched to the point where it couldn't be tightened and had to have over $4000 worth of repairs done to replace the chain and other damaged components. I pulled my owners manual and even searched online for the oem recommended inspections for major components of my car and nothing about having timing chain inspected at any specific mileage point, or any other major components that could fail are listed for major components that could be inspected for wear and tear at said mileage milestones. The fact that prior year models had recalls due to failed timing chains, you'd expect to see following year cars, of the same body style, to have a heightened recommended inspection schedule to make sure the solution to the prior recall worked.

Driving along and engine power reduced causing car to slow significantly - like downshifting two gears. Lights / traction control lights came on dash. Errors flashed - "traction control off", "service stabilitrak", "engine power reduced" all of this not only caused a slight bit of confusion, but placed us in danger with the flow of traffic. A repair shop replaced the gas pedal, however issue persists. Research indicates the throttle body sensor might be at fault - so we replaced this. Issue persisted, so I spent time online and found a gm TSB indicating a known issue and extending the warranty 10 years or 120k miles for p2138 code. At this point, this issue persists intermittently, so we do not consider the vehicle safe to drive.

Driving on the interstate at approx. 70 mph when the vehicle made a lurch forward motion. The vehicle lost power. We were near a exit ramp and coast to the intersection. Vehicle would start but would not shift out of park. We could not move the vehicle. It would not even go into neutral to push the vehicle to safety. The police were called to direct traffic, while waiting for a tow truck. We attempted to restart the vehicle several time so we could it in neutral during the next 45 minutes . The police had to leave and made a final try to put the vehicle in neutral after restarting, it went into neutral . The vehicle was pushed to the shoulder and the police put flares out to advise of a disabled vehicle, and left the scene. After about 2hours and 50 minutes the tow truck arrived. The truck operator got into the vehicle, started the vehicle and put it into drive and drove it onto the flat bed tow truck. Vehicle was taken back to the dealer where it was purchased. We bought the Buick new, 2024, with 3 miles on it. When this occurred it had 1814 miles on it March 13th 2024.

What does it mean when my car says service stabilitrak and service traction control? its main function is indicating that the traction system has been turned off manually to remind you to turn it back on when necessary. However, the stabilitrak warning light may also signal potential damage to vehicle components that allow the system to work effectively. Loss of power to engine, can't stear, feels like its about to blow up. It seems very usual for the Enclaves, traverses and acadias. And I had the same problem out of my 2014 traverse ltz.
