The factory-installed turbocharger assembly on my 2017 Buick Encore failed mechanically while operating the vehicle, creating an immediate and severe roadway safety hazard. The structural failure of the turbocharger causes the vehicle to experience a sudden, unpredictable, and extreme loss of engine propulsion while actively driving. This severe power degradation makes it incredibly dangerous to accelerate, merge into highway traffic, or clear busy intersections safely, as the vehicle fails to respond to throttle input and drops speed rapidly. The vehicle is displaying an active diagnostic trouble code p0299 (turbocharger underboost condition). The manufacturer, general motors, is fully aware of this exact component defect and has issued corporate special coverage adjustment bulletin n232395330 to address cracked turbo housings and wastegate failures on this model. However, because my vehicle is over their arbitrary 120,000-mile corporate warranty limit, gm’s executive resolution team (case #103125607) has issued a final refusal to repair the component. The manufacturer's mileage limitation leaves a documented, highly dangerous engine propulsion defect completely uncorrected on an active vehicle, posing a continuing, severe safety risk to the occupants and other drivers on public roads.
I have went to the dealership for the past two years with this problem and they keep saying they are not getting any codes: when the air conditioner is on it’s pulling the power from the motor and makes it hard to go up hill. Hard to accelerate when going on to the freeway as well. The problem is only getting worse and worse.
Turbo replaced under recall in March 2024 at local GMC dealership. June 2024 oil changed at independent service center and was informed that oil leak from turbo present. Vehicle brought back to dealership in June 2024 where vehicle was repaired for oil feed line being loose at the feed line. July 2024 car taken to independent mechanic and informed that a new turbo is needed. If turbo problem persists it will result in the vehicle shutting down while driving, violent shaking of the engine, and acceleration issues that could result in full engine failure if not resolved. The repairs done for the recall has not rectified the faulty turbo problem. The faulty turbos originally installed and being used for replacements are a safety hazard for any Buick Encore driver.
1. Both of my airbags are showing off. When a passenger is present on the front passenger side, the passenger airbag still lights up as off. 2. If the airbags do not deploy in an accident, due to the sensor this will be very dangerous. 3. Vehicle has been inspected. 4. The manifold and intake did not work. The car only has 87,000 miles on it. The date of number 4 is 2/10/2022.
Everytime I put gas in it doesn't want to start back up. At a stop sign and red light it jerks like it is going to dye out. The check engine light comes on and off. Took back to the dealership only to have it start the problem again the next day.
Poor acceleration causing increase in force on gas pedal. Happens at random times while on flat surfaces, going up hill, around curves with ac on or off. Once acceleration kicks in, speed increases causing the need for applying the breaks. Requires additional space when pulling out on the road to ensure enough time to achieve proper speed. Took to certified dealership for service. Tech unable to duplicate issue and since no codes or service light, they are unable to fix the issue. Picked up the car from dealership. Next day issue continues. Car would also continue to accelerate when foot removed from pedal (almost like cruise control was on), pressed on breaks which did not make a difference. Had to move to side of road & continue try & stop. Made a second appointment to return car back to dealership. Afraid of transporting people in vehicle due to unknown/sticking accelerator issues.
The 2017 Buick Encore would blow out a large amount of white smoke and die in colder weather anytime you step off the gas pedal. It did re-start, however would die several time immediately until it stop smoking. Once it hesitated at highway speed when I let off the gas due to traffic and almost died. The dealership stated that the car computer showed no problems and nothing could be done. They admitted it should have recorded the problem I had, but did not. But the computer was still trustworthy to advise if the car had a problem. I has two near collisions due to the care problems just a few weeks prior to taking it in. I was advised that it was not possible to obtain a print out of the what the inspected because it was in the computer and non-printable. I feel the vehicle is unsafe to car, not knowing if the engine will just stop, and not able to find out why it stop in the beginning. The dealership advised I may need to wait till nest winter to check it again. The fact it almost cause an accident was not important.
