2016 Buick Encore engine problems

“Sequential powertrain and turbocharger failure on 1.4L Ecotec engine following $5,700 in prior engine repairs. Vehicle experienced sudden loss of motive power. Component is covered under GM Special Coverage/warranty. Authorized GM dealer (Mike Haggerty Buick GMC) and General Motors have engaged in warranty evasion, refusing repair authorization and unlawfully retaining the disabled vehicle on the dealership lot for over 70 days. Furthermore, the dealership transmitted a false completed repair record to national vehicle history databases (CARFAX) on August 28, 2026, while the vehicle remained disabled and unrepaired on the lot.”

“power steering failure while driving at highway speeds. In traffic had a warning come on power steering fault. Then wheel was hard to turn. Had to use strength to steer car home approx. 25 miles. Took to dealer they had car for 3 days before repair done. For $1800 repair bill. Said it was a circuit card in the steering system that was the problem. 2015 years had a recall but not 2016 . But the failure from the 2015 is the same with the 2016 year. GM contacted and they deny claim to get repair cost refunded.”

“On my way home in December 2025, my car started to sputter and make noises. All of a sudden the car started going about 10-15 miles. I almost go hit by several vehicles, because they had to put on brakes, I was trying to go up then down a hilly road. I finally was able to get to an Auto Advance Shop, I had to tow the car to Honda then to Buick for a diagnostic test. It had been over a month and I can’t get information in writing what the diagnostic test results are. I’ve had to rent a vehicle for over a month, even though I have a Lifetime Warranty on my power train and motor. I have submitted all my service and repair paperwork to John Miles Buick Conyers Georgia, the GM and Service Department, also I contacted GMC Corporate Office. I have been in a rental car for over a month that I can no longer afford. I don’t know where else to get results for my issue. Thank you, XXX. [XXX]”

“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.”

“Vehicle unable to hold coolant. Local shop says the coolant lines hold pressure and leak appears to be with manifold and turbo. Car has less than 35k miles. There is a recall for this turbo issue with 2017 and up models but why not for 2016, or any other years with same issue?”

“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”
