It is currently available for inspection. •August 11th, 2025: Vehicle stalled in the middle of an intersection as I attempted to accelerate from a stop sign, placing me in immediate danger of collision. •I have had the check engine code read by another independent service center. •No one else has inspected the vehicle •The check engine light has come off and on since January when the problem began after visiting Mavis Discount Tire in sinking spring for a routine oil change. There were no symptoms prior to this first failure that signaled the issue that resulted in the repair. Prior to the incident on August 11th there had been repeated symptoms of an issue even when the check engine light was off. These issues included overheating, smoking, lack of acceleration, and stalling.

My daughter owns a 2019 Buick Encore and the check engine light keeps going on. She took her car to the dealer and was told that it needed a Turbo Bypass Valve and Solenoid valve. The car is just a few months within the 10 year powertrain warranty and the dealer refused to cover as defect. She drives on the freeway 45 minutes to/from work and this is a serious issue that causes the engine to rev hard and not stop as well as stall intermittently.
