NHTSA complaint #11412754, filed 2021-04, 34,000 miles“My check engine light continues to turn on and the code is related to the wastegate actuator/turbo charger. My car is running rough and doesn't accelerate properly. It sometimes rocks back and forth when I try to accelerate. Which is a KNOWN PROBLEM WITH BUICK. GMC REFUSES TO RECALL THIS WELL DOCUMENTED ISSUE. And naturally, it becomes an issue after the warranty expires. Mileage: 67,067”
NHTSA complaint #11735620, filed 2026-05“My engine light came on. The repair shop said I have to replace the fuel pump control module and that it is a known issue with Buick.

Than the antifreeze leaks out, the oil leaks out and one day the car started smoking on the freeway with my children and I inside. It just stopped and haven’t been working ever since. …”
