2016 Buick Encore: check engine light

Filed Jun 16, 2025 · Engine · NC

I believe my turbocharge is malfunctioning. The check engine light is on with code P0299. My vehicle is struggling to accelerate properly putting us in a few close calls while driving. Yes it is available for inspection - I've seen one mechanic on 6/13/25 - scheduled a follow up with a different one on 6/20/25 and have an appointment scheduled with GM on 7/1/25 should it go that far. I cannot pull out in front of vehicles even with double the normal amount of space confidently due to my lack of acceleration putting my family - pregnant wife and 1 year old at risk. We floor the gas pedal to try and get what should be normal acceleration but sometime it responds normally which has put us at risk of hitting vehicles in front of us. Yes - it has been inspected and we're getting more opinions. First appeared early June but no other warnings

Acceleration was reduced immediately on the freeway after the check engine light came on the day before with a P0299 code for turbocharger repair. Now the vehicle will not start and the dealership service said an additional code of po366 is now showing. Are these related? The turbocharger has an extended special coverage, but not engine repair that is likely the result of the turbocharger failure.

In 2021, My ex husband received a notice from Buick extending the warranty to 120,000 on the Turbo Charger fuel injector due to failure in many vehicles. It was not included as a recall. In the State of Texas, vehicles must have an annual inspection to remain legal to drive. Each vehicle receives an annual Sticker. My sticker and inspection were due in July. In May of 2024, my check engine light came on. I took it to Autozone to diagnose, and they said it was the turbo charger. Since I had no idea my ex-spouse had a letter, I purchased fuel injector cleaner and did this every week. Chevron 92 has always been my gas of choice. Unfortunately, it only cleared the engine light for a few days and my vehicle failed inspection at 120,000 miles. I took my Buick Encore to a traveling mechanic, who cleaned the injectors (supposedly), and after driving about 100 miles and in July finally passed inspection to avoid a citation. At 122,00 miles, on [XXX] I drove my Buick to Dallas Texas, 571 miles one way. I barely made it; the check engine light came on again and the vehicle could barely accelerate. I stopped multiple times to install injector cleaner, used only the best 92 gas at chevron. When I arrived, i took my 2016 Buick Encore to Firestone. They diagnose the Turbo Charger again. unfortunately, the vehicle had reached 123,000 miles by then. They cleaned the Turbo charger but could not replace it. At that time, they let me know that might be a manufacturers defect, since this part should definitely last much longer than 123,000. Barely making it home again, with my [XXX] mother with me, I took my vehicle to Gay Buick GMC to get the Turbo Charger replaced. Buick informed me this was too far past the 120,000 and refused to even replace the part if I paid for labor. This is a $2,653.48 cost. May I ask for your assistance in a remedy, at least for the $700.00 part? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The turbo on my 2016 Buick Encore hasn't been working right for about a year. My engine light has been on consistently everyday for about 8 months. I've taken it to the dealer to get it repaired, and there is a bulletin - Reference Number A212338300 - but for some reason my VIN doesn't meet the requirement of the turbo replacement - even though the bulletin is for a turbo replacement. Why is my turbo NOT covered by the bulletin? Clearly there is an issue with the part since a bulletin exists in the first place.

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.

2016 Buick Encore VIN # [XXX] with 67,584 miles. My car's check engine light came on. Upon checking the code at O'Reilly Auto I was told I had to see a mechanic as it showed code p0299, Turbo. I made an appointment at Garrigans Auto repair Shop, a reputable shop. After they inspected the SUV I was told the turbo had a crack and needed to be replaced. On 7/14/2023 I had the repairs done at a cost to me of $1,480.49 (attached). The car runs fine now. On 10/12/2023 I had another repair done on the car. This was the turbo emissions coolant line. While there, Thomas at the counter said he just received the notice of a "Special coverage [XXX] Turbocharger Replacement". I thanked him and contacted Buick. I talked to Diana and gave her my VIN number. She informed me of the extended coverage as long as my car was not more than 10 years old or more than 120,000 miles. My car has 67,584 miles (notice attached). She sent me the form and I filled it out and returned it (copy attached). The case number is [XXX] (attached). On 10/23/23 I received a call from Diane at Buick informing me my claim was denied. She said it was denied as it was not done at the dealership. If I had sustained a problem before Nov. 2021 I could file a claim but it had to be submitted by Nov. 2022. My work was done this year at a local shop. She said since it was not done at the dealership it was not covered. I told her I never knew of the 'special coverage' until after the work was done. She said it is not refundable. I asked for a supervisor who said the same thing. My issue is there is a serious malfunction of the turbo that could happen while I am driving down the interstate at 70 miles an hour only to have sudden reduced power or timing chain breakage causing serious damage to the car not to mention being hit from behind or when passing a semi due to loss of power or total engine malfunction (attached). Now I am contacting the federal safety agency with my complaint. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 55

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 turbo malfunctioned and made it not possible for the car to accelerate on the freeway. My safety was put at risk because the car would no longer accelerate at the speed limit which meant I was going slower than traffic. It sounds like this is a common problem for these cars in this year and 2017. The vehicle has been checked out by a mechanic. Nothing appeared until after it happened then the check engine light was on. sources that this is a common problem for this vehicle https://www.carcomplaints.com/Buick/Encore/2016/engine/engine.shtml https://www.driveandreview.com/buick-encore-problems/ https://buickforums.com/forums/threads/2017-buick-encore-turbo-failure.52583/
