At 15,000 miles the check engine light came on while going to a store. At the store, the vehicle was put in park and tried to shut off engine. The dash said "shift to park". Took to the dealer, was told sensor went out on transmission. They said it was the electronic controle module. They didn't think that was part of the drive train warranty. When I looked online I found many other Buick owners complained of same issue. Posting online that they are slamming shifter into park up to 20 times to get sensor to register that it is in park so they can shut vehicle off. I feel it is a known buick problem and gm doesn't know how to fix so they won't issue recall. If you can't shut the vehicle off, the engine could over heat, not to mention run out of gas. And if people are slamming the shifter in and out of park to get vehicle to shut off an accident could occur in a parking lot or street if the sensor cannot read the shifters position properly. What if the sensor senses improperly on the freeway, is my vehicle going to come to a sudden stop on the freeway? General motors has let this gone on too long.

Within first couple months of ownership we had a wheel insert come off. We had it replaced at dealer Dec 2022 and noted it was two small bolts holding on the insert to actual wheel. The screws (2) appeared to have sheared off and are in line with brake rotors, calipers, and wheel itself when dislodging. The actual insert goes forward and can hit other cars and damage finish and other items as a projectile. We then had another do the same thing on different wheel 12 months later. Same issue. Same resolve as metal screws/bolts go directly into plastic insert which has no metal lining and no protection against breaking from stress, cleaning, and high speed turbulence thru this area. Less than a year later and we now have one missing insert that came off during highway, one loose we removed and found one bolt missing and sheered plastic, and a third one that is loose. Dealer will repair and replace under warranty but would not put on lift and check all inserts. There are approx 5 inserts per 18 inch wheel. This is a safety issue as the bolt will come out of fall into the wheel brake system. It could get lodged into calipers or pads and cause harm at least. These screw bolts are small but larger than anything nominal.
