2016 Buick Encore: engine stalls while driving

Filed Jan 7, 2026 · Electrical, Engine · OH

I was stopped at a traffic light and began moving forward to make a turn into traffic. As I activated my turn signal and started to proceed through the intersection, the vehicle suddenly stalled and shut off without warning, causing an immediate loss of power while the vehicle was in motion. Another vehicle was entering the intersection at the same time, creating a near-collision situation. I was forced to restart the vehicle in traffic. The incident occurred within less than 250 miles of purchasing the vehicle. The vehicle had recently received an oil change and inspection. No warning lights or messages were observed prior to the stall. This event created a serious safety risk.

On Wednesday February 27, 2024 while driving on the highway suddenly after about 15 minutes the engine light came on stating "Engine Overheating - idle engine." The car decreased speed to about 40mph in a 60mph speed zone and then continued to decrease to 20mph with black smoke excessively blowing out of the exhaust and then a rattling /knocking sound continued from the engine until the car stopped in which I was able to pull over to the side emergency lane. My safety was at risk due to the car's sudden decrease in speed to a stop on a busy and crowded highway. I have been on the highway at least 5-6 other times in which the car almost stops on a busy expressway. I have brought the car to the GM dealership on several occasions in which I received 2 recall letters: one September 2019 (regarding the evaporative emissions purge valve does not properly close) and another recall letter November 2021 (regarding a condition that could cause the turbo charger to fail due to a sticking wastegate actuator linkage) from GM describing that there were recalls on my 2016 Buick Encore. After bringing the car to the GM dealership where I purchased the car, I explained that the engine will almost come to a stop. I described that it was very frightening to drive the car like this. The service center did complete repairs however the stalling engine continued and I continued to bring the car to the dealer complaining of this concern each time. The vehicle was not inspected by the police or insurance representatives. The Engine light sensor would continue to appear on the dash in which I brought this to the service department's attention at the GM Dealership. The GM dealership tried to correct the engine's problem but never succeeded, therefore the engine was defective and unsafe to be driving.
