Front driver and passanger tire hubs made a warble sound. Took to a good year auto shop for inspection and the driver tire disconnected from the hub. Was informed this is NOT a normal wear and tear issue given the year and mileage of the vehicle, and to report it immediately. There were no warning lights just sounds reported and investigated to find cause.

Loss of acceleration due to cracked turbo boost. I guess you need a special 2019 vin # to be included in a recall. Recall for 2017 2018 and a select few 2019 very disappointed with this big repair job that is a known problem. I'm done with Buick.

92,000 miles my catalytic convertor went bad, had for 5 years. This resulted in lag when trying to accelerate and pull out in traffic. It cost $3,000 to fix as well as the turbocharger being broke. The blind spot detection to passenger side mirror stays on at all times and should only come on when there is an object detected in the right side blind area. I'm [XXX] old and have never ever has a catalytic convertor go bad. Buick should be responsible for these repairs.
