2021 BUICK ENVISION

EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE

General Motors, LLC (GM) is recalling certain 2020-2023 Cadillac CT4 and CT5; 2021-2023 Buick Envision; and 2022-2023 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles. The daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: DRLs that do not deactivate as intended may result in a glare, reducing visibility, and increasing the risk of a crash.

AIR BAGS

The contact owns a 2021 Buick Envision. The contact stated that when the vehicle was started, the air bag warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 80,000.

POWER 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.

POWER TRAIN

The contact owns a 2021 Buick Envision. The contact stated that while stopped in traffic on the highway, while accelerating, the transmission started slipping and the vehicle jerked abnormally before starting to drive normally. The vehicle was taken to a local dealer where the vehicle was diagnosed, and the contact was informed that additional diagnostic testing was needed to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 34,950.

VISIBILITY/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.

UNKNOWN OR OTHER

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.
