Engine overheating by model year
What owners say
Two different issues occurred. While driving the check engine light came on and then went off about 10 minutes later. While driving the vehicle to get check engine light code checked temperature suddenly jumped from normal operating temp just below mid to the top with instrument panel dinging saying engine overheating idle engine. As trying to make way to side of road the blind spot warning on passenger mirror began flashing constantly with no traffic within 1/4 mile from vehicle and instrument panel stating blind spot not available. Once able to get to have code checked showed same code that had been addressed with the replaced turbo 0299. Thermostat replaced less than 19k miles prior. When engine overheat came on power diminished rapidly.
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.
Turbocharger failed which can eventually cause engine seizure. Independent mechanic diagnosed and repaired after Buick dealer told me I was out of warranty. After repair I located a letter from Buick with my vin number on it dated November 2021 (after my warranty expiration) confirmed that the turbocharger might fail and they would replace free of charge within 10 yrs or 120,000 miles of vehicle purchase. Prior to incident of turbocharger fail, my vehicle alerted me with with a loud tone of "Engine overheat, engine Idle" - all the engine oil and coolant ran out while driving.. Mechanic replaced water outlet, then a short time later service engine light came on with code for turbocharger failure.
The contact owns a 2016 Buick Encore. The contact stated while driving 55 MPH, the vehicle accelerated independently with unknown warning lights illuminated. The vehicle started smoking and overheating. The contact was able to pull over on the side of the road and shut off the vehicle. The contact attempted to restart the vehicle however, the vehicle would not restart. The vehicle was towed to an independent mechanic to be diagnosed. The mechanic retrieved DTC codes: P0700, P0243, and P0333. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 123,000.
