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.

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.
