My vehicle is taking oil into the engine and is available for inspection. The mechanic says some component in the engine is taking in oil. I am losing about 3/4 of a quart every 500 miles. He said his best estimate is in months to a year it will blow the motor. I have not taken it to a dealership just the mechanic company I use. No I got a message saying that I needed to add oil about 2 weeks after an oil change. My mechanic checked the oil levels for a couple weeks after that. And thats what I was informed after checking oil levels.

Shift gear won't go into park. Emergency brake locked. Had dealer look at it and apparently a valve is blocked in transmission. Seen a number of complaints about transmission issues on this particular model yet this Vin is not on recall. GM says it needs a whole new transmission which will be $10,000. Really?? The least they could have done was fix this vehicle in good faith because of past recalls. Now I'm stuck with no vehicle and still paying for the finance.

My car started making a loud and rattling noise and when I had my vehicle looked at there was a huge crack in my exhaust pipe which could potentially be leaking harmful toxins in the cabin of my vehicle. I have been to so many places who say they don’t have what they need to repair this and that I need to reach out to GM. I have seen over 30 similar stories in these complaints. This is very unsafe and something needs to be done about this for the 2020 model as it has been done for others. We are afraid to even keep all the windows rolled up with our children inside for fear of carbon monoxide leaking through.

Vehicle suffered a catastrophic, uncommanded electronic and mechanical system failure within 30 days of purchase, resulting in a severe crash.Prior to the incident, the vehicle exhibited a violent, unexpected jerking motion while accelerating up a highway on-ramp, though control was briefly regained. A few days later at the end of May, while driving in the rain, the electronic systems completely failed with zero dashboard warning lights or error messages appearing.The vehicle completely overrode driver input, veering uncontrollably from lane to lane on its own. Simultaneously, a total loss of braking power occurred; pressing the brake pedal had no effect on reducing the vehicle's speed. To stop the runaway vehicle and prevent hitting other drivers, I was forced to intentionally steer the SUV into a physical wall. The impact deployed components, caused orange engine coolant to leak, and forced the electronic precision shifter into Neutral on its own before the vehicle lost all electrical power. The steering wheel airbag deployed during this initial impact.Approximately 5 minutes later, while the vehicle was disabled on the road and after I had safely exited, a secondary vehicle struck my stationary car, which caused the majority of the remaining airbags to deploy.Detroit Police responded to the scene and filed an official crash report noting that I 'lost control' and struck the wall, but the responding officer failed to document the mechanical/electronic brake and steering failure reported at the scene.This simultaneous loss of eBoost braking control and electronic steering assist strongly aligns with the current federal safety investigation into GM vehicles (NHTSA Case PE24011). The vehicle is currently parked and being preserved exactly as-is at my residence to serve as evidence, as the module memory holds the Event Data Recorder (EDR) data proving full brake application during the failure. I am requesting an immediate investigation into this VIN.

My car starting making a loud noise upon start up and continued while driving, sounded like a GoCart exhaust system and was not normal. It just sounded loud and would get louder when accelerated until the car ran for awhile. I first noticed it at about 83,500 miles. I took to the dealer for checkup at 83,950 miles when I could get an appointment. The dealer (Elco Chevrolet) confirmed the problem upon hearing and looking under the car, there is a bracket broken on the exhaust system and the catalytic converter has a hole/crack in the molding. Our safety is at risk if the exhaust with the crack would create fumes harmful when driving the car and risk of injury if the exhaust would fall off upon driving due to bracket broke. There were no warning lamps or messages from the car. I am submitting this problem as upon discussion with the dealer and investigation online about this, appears that this is a problem with GM vehicles with this make and model, Enclave and Travers, however, my year was not flagged for a recall already established. When I tried to investigate with GM they stated it was because my car was not identified likely due to parts or timing. I am asking to further investigate as there may be a problem with the design of this exhaust system that caused this issue early in the mileage of this car. Asking for further investigation into the make and model of this year for the year 2020.

The mounting bracket welded to the front exhaust pipe (near the flex section) broke off due to weak factory welds. As a result tearing a hole in my exhaust pipe and potentially leading to exhaust fumes leaking into the cabin of the vehicle. In my opinion this defect should be addressed as a safety issue if not repaired.
- Seat belts
Drivers side seatbelt would not latch and dealership said it needed replaced.
- Engine
Front exhaust pipe separated from its mounting bracket causing a consistent rattle. This condition is exactly as described in "N222385510 - Special Coverage Front Exhaust Pipe", released in May 2023. Exhaust components in this vehicle are materially the same as the covered 2021 vehicles and thus this vehicle should be similarly covered. Issue has been confirmed by a dealer and is available for further inspection.

I am submitting this complaint regarding a paint defect on my 2020 Buick Enclave. The passenger-side rear door has significant top-coat peeling and flaking, exposing the primer and metal underneath. This deterioration is not normal wear for a six-year-old vehicle that has been properly maintained and protected from environmental conditions. The pattern of peeling indicates a failure of the top coat or clear coat applied during manufacturing. The paint layers are separating prematurely, reducing corrosion protection and long-term durability. Exposed metal increases the risk of rust, structural weakening, and potential failure of the door panel, which may affect occupant safety in the event of a collision. I am aware that similar paint adhesion failures have been reported across multiple General Motors vehicles, and class-action lawsuits are currently pending alleging defective basecoat and clearcoat systems that cause premature peeling, bubbling, and flaking. The number of complaints suggests a broader manufacturing issue rather than isolated consumer misuse. Although my vehicle’s limited warranty has expired, the defect is clearly premature and manufacturing-related. A properly applied top coat should not fail this early, especially on a vehicle that has been routinely washed, waxed, and stored in normal conditions. I respectfully request that NHTSA review this issue and consider opening an investigation into paint top-coat failures on Buick and other GM vehicles. Premature paint failure affects corrosion resistance, vehicle longevity, and consumer value, and may compromise the safety of occupants and other drivers if corrosion spreads or structural integrity is reduced. I am willing to provide photographs, documentation, and maintenance records to support this complaint. Thank you for your attention to this matter and for your commitment to consumer safety and manufacturing accountability.

I am submitting a complaint regarding premature exhaust system failure on my 2020 Buick Enclave involving the front exhaust pipe/exhaust manifold/catalytic converter assembly. The issue appears very similar to the conditions described in GM Special Coverage programs N212356540 and N242445280 involving exhaust pipe and bracket failures on related GM crossover platforms. The mounting brackets/support brackets on the front exhaust pipe appear to fail or separate, which places excessive stress on the flex section of the exhaust system. This movement and stress can cause the flex pipe/manifold area to crack and may ultimately damage the catalytic converter assembly itself. My vehicle developed: Exhaust leak Loud ticking/exhaust noise Rich/lean oxygen sensor fault conditions Exhaust fumes entering or potentially entering the cabin Passenger dizziness while riding in the vehicle Concern for carbon monoxide exposure The repair facility documented that the exhaust leak should be repaired as soon as possible because exhaust fumes may enter the vehicle cabin. The estimated repair cost is approximately $1,700 for replacement of the integrated catalytic converter/exhaust manifold assembly. This appears to be more than ordinary wear and tear. The failure pattern is consistent with bracket/support failure causing abnormal stress and cracking in the exhaust system upstream near emissions components. Because these failures can allow exhaust gases and possible carbon monoxide exposure into the passenger compartment, I believe this issue represents a significant safety concern and warrants investigation for 2020 Buick Enclave vehicles and related GM crossover platforms.

Had to have it towed . The first time that the transmission gave issues it didn't lock up in park it locked up in drive and we couldn't put it in park I was able to get it to the dealer to get worked on it was still under warranty at that time the second time it wouldn't go out of park and could not move it it was stuck wherever we happen to be at and it would not move when they loaded it on the tow truck to tow it down to the dealer the wheels were locked up cuz it was in park and we couldn't it had to just be drug onto the truck.

I am submitting this formal complaint regarding serious mechanical and safety issues with my 2020 Buick Enclave. These issues have created ongoing financial hardship, significant safety concerns, and an urgent need for investigation and resolution. Over the past several months, my vehicle has repeatedly displayed low‑oil notifications, sometimes occurring within one month of receiving a full oil change. During a recent visit to my mechanic for yet another low‑oil alert, he recalled that I had previously brought the vehicle in for the same issue. After conducting a more thorough inspection, he informed me that there was a failure within the engine/transmission assembly. He showed me the area where oil was seeping from the engine. I also inspected the oil filter and oil plug, both of which showed no signs of leakage. Following this diagnosis, I brought the vehicle to Royal Buick GMC. Their service department performed a SAVI Dongle test and a GM‑Certified Multi‑Point Inspection. The service technician informed me that the vehicle requires a complete engine replacement including the following: replacement of the engine, repair of a rear main seal failure, resealing of the oil pan, and replacement of the lower control arm. It is my belief that these issues are consistent with reported problems. In addition to the oil‑related failures, I have experienced sudden acceleration and jerking while driving. These incidents are alarming and pose a serious risk to my safety and the safety of others on the road. I am deeply concerned that this defect could lead to an accident through no fault of my own. This vehicle is my only means of transportation for work and for caring for my family. The cost and severity of the required repairs are catastrophic, and I believe the manufacturer should be held responsible for addressing these defects. I respectfully request that the NHTSA investigate these issues and assist in ensuring that GM/Buick replaces the engine for its safe operation.

Component/System Failed: Tire Sidewall (Continental CrossContact LX20 EcoPlus+, Size: 255/55R20 107H). I am reporting a potential safety defect regarding my Continental tires. While my specific mold number (S-421232) is not currently listed in NHTSA Campaign 20T018000, the tires were manufactured in the same week (DOT 0420) and show symptoms consistent with the overcuring defect described in that recall. I have observed unusual marks and [mention what you see: e.g., "cracking," "distortions," or "bubbling"] on the sidewall. These marks appeared without any impact or road hazard. Given that this specific model and production week are already associated with sudden sidewall breakage and carcass failure, I am concerned that the existing recall scope is too narrow and that my tires pose a similar risk of sudden air loss or crash.

The vehicle developed an exhaust leak caused by both weld points on the front exhaust pipe breaking. A dealership inspected the vehicle and confirmed that the exhaust welds had failed, creating a hole in the exhaust pipe and triggering a P0420 catalyst efficiency code. The failure occurred at approximately 31,500 miles. The exhaust leak caused increased exhaust noise and emissions warning codes. The dealership recommended replacement of the front exhaust pipe assembly. This appears similar to known failures on the Buick Enclave and Chevrolet Traverse platform where the front exhaust pipe mounting bracket separates from the pipe due to weld failure. GM has issued special coverage adjustments for similar exhaust pipe bracket weld failures on other model years of these vehicles. The failure occurred at relatively low mileage and appears to be a structural weld defect in the exhaust system.
