   got a check engine light on, took to dealer was a code 1098, the part is on back order told that it would not be available until middle of may, this happened to me at the end of march, now am learning that GM issued a recall on that part for their diesel Duramax engine, I think it is a GM wide problem.

The contact stated that while his wife was driving at an undisclosed speed on the freeway, the vehicle unintendedly accelerated around a corner, with the floor mat stuck under the pedal. The driver depressed the brake pedal for an extended time, but the vehicle continued accelerating. The driver pressed the park button, which slowed the vehicle, and the driver was able to pull over safely. There were no warning lights illuminated. The vehicle was taken to the local dealer, and the owner was informed about a possible recall. The dealer determined the failure was due to a stuck floor mat and sudden unintended acceleration. The front and rear brakes were replaced along with the floor mat. The floor mat was PN: 84734211. The manufacturer was not contacted. The failure mileage was approximately 37,000. The VIN was not available.

   When I start at a low speed it's like it does not know which gear to go in. You push on the gas and it does not move much and then launches forward. It has done this since I purchased it in April 2025 used.When in auto stop and the engine starts up with my foot still on the brake, sometimes it will lurch and buck. Buick dealer did do a transmission fluid flush and it still does the same thing daily.

The vehicle was taken to the dealer several times, but the cause of the failure could not be determined.

8. Filed Jun 24, 2025Failure Jun 23, 2025St. Clair Shores, MIPower train

   This has happened about 4-5 times now, car has approximately 17.5k miles. While accelerating attempting to reach speed limit, transmission has slipped out of gear and power to wheels is not happening. Have learned to switch into neutral and then drive and transmission will reorient and grab the appropriate gear and reengage the power to the wheels. This occurrence does not throw off any codes so it appears random. Took it to the dealer and they said it would be two weeks before their transmission guy could take a look at it and try to recreate. Since it is not throwing codes, elected to continue driving since it usually occurs in the 25 - 35 mph range.

10. Filed Jan 6, 2025Failure Jan 22, 2024Ira Township, MIVisibility/wiper

    When driving 2021 Buick Envision, the windshield and side windows do not defrost with HVAC set to defrost mode. Service Climate system is displayed on dash. Vehicle was inspected by dealer finding replacement of HVAC case half housing required on 1/22/24 ( a year ago). GM (OEM) has been in contact but has failed to provide a solution after 1 year of trying to obtain a part from their system. This condition results in immediate fogging condition of all windows without warning presenting a visibility safety hazard for the driver and surrounding vehicles. Sorry GM, but a rag to wipe the window is not a good solution. It has been a year with no urgency from GM to remedy the issue. This is deemed a critical function for safety and GM does not take it seriously.

    I think it may be either fuel propulsion system or it maybe something electrical. I don’t really know. It is available for inspection at this time as it has been at the car dealer repair shop for about a month. My safety is put at risk because about seven or eight out of 10 times that I attempt to start the vehicle, it will turn over by pushing the button, but will not start. I work until past dark many nights and my vehicle not starting is a big safety issue. The dealer said they reproduced it, but they have not been able to reproduce it again. Again, when I have it, it happens more than half the time. The dealer tells me they are communicating with the Buick engineers as the computer does not show any issues. They have so far not being able to determine the problem. there were no warning lamps or anything like that. It started happening occasionally when it was under warranty, I took it in twice to the dealer repair shop and they both said they could not reproduce the issue at that time. This is the third time I have brought it in and it is just past the end of my warranty.

    Not safety, but GM recalled 2021Trailblazers to replace Evap Purge Pumps on vehicles showing check engine light resulting in bad purge pump diagnosis. Why only Trailblazers? I recently had to replace one on my 2021Envision at 37,588 miles after my check engine light came on. Fortunately I bought the extended insurance when I purchased my new vehicle and only paid the $100 deductible. Otherwise it would have cost me $404. If they knew of problems for that year, why not send out letters to other owners of GM vehicles? Thank you.

    When I push on the accelerator the car hesitates and then surges forward. I took the vehicle to the dealership where they recreated the problem however it was not throwing any codes. After examination they determined that the problem was turbo lag. I was advised to continue driving the car as usual until it throws a code or turbo fails. I believe that the vehicle randomly hesitating could leave you stranded in an intersection with oncoming traffic, and when if surges puts you at risk for a rear end collision. When I asked the service rep what will happen if the turbo fails, she said pull over and call on-star. I'll be traveling through the mountains for the holidays, it worries me that if the turbo fails I could be stuck on the side of the road in winter weather.

    My vehicle's motor stopped without any warning in the middle lane of a busy freeway. I put the emergency flashers on but when I tried to restart the motor it overrode the flashers, causing a semi truck to just miss hitting me. The transmission went into Park mode and since this car is electronic shifting it would not let me put it in to neutral when the motor is not running . People stopped to help me push the car off the road but we could not get it into neutral. Very DANGEROUS situation to be stuck in a center lane on a busy freeway. ODOT and state police that stopped to help me said that they have never seen anything like this. Towed the car to a Buick-GNC dealer where they have had it for over 2 weeks now. They say that the fuel pump control module failed and they are on back order. My car has 11,200 miles on it.
