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.

Car has airbag light on. The car keeps leaking which then caused damage to my spark plugs and coil pack. It then led to the O2 sensors being burned. It has been at the dealership multiple times within a 3-week time frame. The low fuel light comes on when it is on a full tank, then it begins to hesitate and the car lunges forward when at a complete stop. Tires act like they cannot keep traction when all 4 tires are brand new and front rotors and brakes have been replaced. Yes, all my concerns have been brought to many dealerships' attention. It is unsafe and unreliable. The dealership said they could not replicate the issue but once I get back into my car it starts up.

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

SUV has ran hot and had it towed on 3 separate occasions when this happened. Had thermostat and water pump replaced. Not fixed. Coolant keeps running out if bottom of suv. It is at dealership and blown head gasket and probably much worse. Apparently these models have something wrong with cooling system. The engine cost will be about what I owe on it. Buick needs to pay for another engine for my SUV. I have a warranty but they won’t honor the engine replacement and I’m out of a vehicle.
