2021 Buick Encore

Intermittent Service Brake Assist Light with very hard brake pedal and almost no breaks backing up. Have had it to several shops who said it was a turbo booster issue so scheduled service with Patriot GMC Boyertown Pa. Also intermittently has little to no power causing driving hazard suddenly especially uphill. Seems to mostly happen during rainy days.

Turbo Charger failed while passing a semi-trailer truck causing a severe lack of power and almost causing a head on collision with on-coming traffic. I had 3 passengers at the time. The problem has been confirmed by a independent service center and I am getting a second opinion from a dealer on 2/3. The check engine light did come on when it happened. There were no symptoms prior to failure. I have since researched the problem and found that Turbo Charger failure is the #1 issue with this make and year.

Already had turbo go on this car once back in July 2022. Mechanic replaced turbo with another one (used with 20,000 miles on it) due to the turbo for this car being on backorder. Now my car is throwing P0299 after about 20,000 more miles being put on the used turbo and a P0420 code. Changed rear catalytic. Changed upstream O2 sensor, changed wastegate solenoid, turbo seems to be working fine, no noises, but losing power going up hills at highway speeds. Seriously unhappy and no recalls on this vehicle but it has the same turbo as other vehicles that has had recalls!!! I think this should be a recall!!!
