   Intermittent Service Brake Assist Light with very hard brake pedal and almost no breaks backing up. Have had it to several shops who said it was a turbo booster issue so scheduled service with Patriot GMC Boyertown Pa. Also intermittently has little to no power causing driving hazard suddenly especially uphill. Seems to mostly happen during rainy days.

   I have continuously had my check engine light pop on. I have took it in twice for them fix the issue which is the purge sensor. It did not fix the issue because the light just pops back on. This has caused issues with me passing emissions and has been an headache shortly street I obtained the vehicle.

   The contact owns a 2021 Buick Encore. The contact stated that while driving at an undisclosed speed, the brake pedal was firm while depressed. The contact had to slam on the brake pedal to stop the vehicle. The contact stated that the Hill Assist message was displayed. The brake pedal was pumped several times before the brake pedal released. The vehicle was taken to an independent mechanic, who determined that the brake sensor needed to be replaced. The dealer and another dealer, Mangino Chevrolet, INC. (4447 NY-30, Amsterdam, NY 12010); were made aware of the failure, but informed the contact that there was no recall associated with the VIN. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V588000 (Service Brakes); however, the VIN was not included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 38,000.

   Took to the dealership. They stated my flex pipe had melted and the o2 sensors are stuck in the pipe need replacement as well. They have to replace flex pipe and everything leading to the 2nd o2 sensor. They stated there was no damage or tampering to the flex pipe. This should not have happened in this new of a vehicle. This is a dangerous and costly repair that falls on a faulty flex pipe and not covered by the warranty.

   Turbo Charger failed while passing a semi-trailer truck causing a severe lack of power and almost causing a head on collision with on-coming traffic. I had 3 passengers at the time. The problem has been confirmed by a independent service center and I am getting a second opinion from a dealer on 2/3. The check engine light did come on when it happened. There were no symptoms prior to failure. I have since researched the problem and found that Turbo Charger failure is the #1 issue with this make and year.

   The 2021 Buick Encore was listed by the NHTSA as having a parts recall with the Evaporative Emission Purge Pump, yet when I look up my VIN and talk to the dealer, I’m told the vehicle is not recalled, even though I’m having the exact same issue that was described in the recall. I’ve been delaying servicing because I was told the part was on back order but now they have it in stock and I’m hoping I don’t have to pay for it since my issue is the same one that was listed in the recall.

   Already had turbo go on this car once back in July 2022. Mechanic replaced turbo with another one (used with 20,000 miles on it) due to the turbo for this car being on backorder. Now my car is throwing P0299 after about 20,000 more miles being put on the used turbo and a P0420 code. Changed rear catalytic. Changed upstream O2 sensor, changed wastegate solenoid, turbo seems to be working fine, no noises, but losing power going up hills at highway speeds. Seriously unhappy and no recalls on this vehicle but it has the same turbo as other vehicles that has had recalls!!! I think this should be a recall!!!

   Had an oil change done 6/13/22. 6/21/22 Temp gauge rose to 3/4 mark, AC shut off, car really hot under hood, loss of power, car threw crankshaft position sensor code which we replaced. Had the temp gauge do it few more times from 6/21/22 to 8/13/22 when temp gauge did the same thing and car really hot under hood, smoke from tailpipe and loss of power. Took to repair shop, they want to replace engine, oil lines, turbo and gaskets. Car has 121530 miles on it.
