The failure mileage was approximately 13,978.”Owner report · Steering · Jan 2026

“When starting from a traffic light after the green light, the car made mechanical noises and would not accelerate above approximately 25 mph. It seemed obvious at the time that the transmission had failed, which was later confirmed after being towed to the dealership. There were no warning lamps or messages displayed; however, during the previous days, there were a few instances when the transmission "shifted" hard (this seemed odd considering it is a CVT transmission).”Owner report · Power Train · Jan 2026

“No accident just a concern. On my Buick the clasp for the front set belts are buried between the seat and center console. Making the fastening and unfasting very difficult. The further the seat is forward the more difficult it is. I guess my concern is this over sight may hamper the use of them or possibly cause entrapment during a stressful situation.

Turning on and off the vehicle doesn’t fix. Intermittently Maps become distorted while using USB-C, unable to use.

“Vehicle struggles to stay running in the heat with the air conditioning running. Low voltage codes pulled at dealership. When the air conditioner is running there is an awful toxic smell from the vents both with or without recycling the air. Vehicle struggles to slow then accelerate, such as normal driving conditions in rush hour traffic. Poor ability to accelerate, hesitant and jolting. AWD model with winter package in the desert doesn’t fair well.”Owner report · Electrical System,Unknown Or Other,Engine · Aug 2023
