2015 Buick Encore Complaints

ENGINE — Filed 06/26/2026

Weber road auto service replaced the engine using county PRC and out-of-pocket funds, and the newly installed used engine has an active engine oil cooler leak, creating an immediate vehicle fire and sudden engine stalling hazard. Also there’s a leak at the ac compressor, condenser and coupler valves. This was discovered by Buckeye Auto Service. No repairs have been made as first shop keeps brushing me off.

The turbo in my vehicle has a check engine light come on and than the engine does no act right. The repair shop that looked at car stated that the manufacture knows this is a known issue and they have not made a recall as several cars my year range has this going on. If this is a known issue why is there no recall. I worked had for my car and I can not afford the repair of a know issues with the turbo as it cost a lot and I should not have to cover this as it is apparent this is a manufacture defect that is known. It puts me as risk as the car is not preforming properly and it jumps and does not go properly when it has the issue arise. I will get hit for not going after I come to a stop and will not accelerate properly. This issue appeared 2 months after I purchased the car and I took it to a shop who told me he has tried to contact Buick to cover the repairs for others and gets no where. I think that the manufacture knows and will not repair something that is not the owners fault but there shafty part and they know this as it was a recall in other years of my vehicle.

STRUCTURE — Filed 11/01/2022

The painting on my 2015 Buick Encore started peeling about 2 years ago and has continued to worsen, and I am concerned about the longevity and overall appearance of my vehicle. As a loyal customer, I expect the paint job to last for a reasonable amount of time, and I believe this issue should be addressed by the manufacturer. I would like to request that Buick fixes this issue free of charge. I understand that my vehicle is no longer under warranty. This is particularly concerning as the peeling paint is affecting the resale value of my car, and I would like to maintain its value as much as possible. I understand that paint issues can occur, and I appreciate that this is not necessarily a reflection on the overall quality of the vehicle. However, I am requesting that Buick take responsibility for this issue and repair the paint free of charge. I believe that the paint peeling issue is covered under the vehicle's warranty, and I hope that I am hopeful that Buick will make every effort to keep this cost to a minimum and to ensure that I am not left out of pocket for a problem that is beyond my control.

FUEL/PROPULSION SYSTEM — Filed 06/06/2024

My check engine light came on so I took it to a repair shop. They put it on their Diagnostic System Check Computer and the code #PO299 came up. After further inspection and investigation, the failed part is the Turbocharger- A1140104N. This vehicle's, vin number, model year and mileage qualifies it for warranty replacement and labor for the faulty part. However, because it is a Buick and not a Chevy the dealership is not authorizing the repair, even though it is the exact same system and part that is being replaced in the Chevy models. Without this part functioning properly, it affects performance and the car's ability to accelerate when needed which makes it a hazard to drive if you should need to accelerate quickly.

VEHICLE SPEED CONTROL,SERVICE BRAKES — Filed 03/06/2018

THE CAR HAD BEEN PARKED IN AN UNHEATED GARAGE FOR MORE THAN 24 HOURS. I STARTED IT, PUT MY FOOT ON THE BRAKE PEDAL, AND PUT IT IN GEAR (R). THE CAR LUNGED BACK AT A HIGH RATE OF SPEED. MY FOOT WAS STILL ON THE BRAKE. TO AVOID HITTING A VEHICLE BEHIND IT IN THE DRIVEWAY, I SHIFTED TO DRIVE (D) AND THE CAR IMMEDIATELY STARTED FORWARD STILL AT A HIGH RATE OF SPEED. THE BRAKES DID NOT SLOW THE CAR DOWN. I BUMPED THE FRONT WALL OF THE GARAGE AND AGAIN SHIFTED INTO R. THE CAR STARTED MOVING BACK AGAIN AND THE BRAKES DID NOT WORK. I TURNED THE ENGINE OFF AND THE CAR BEGAN SLOWING AND CAME TO A STOP AFTER BUMPING THE VEHICLE ABOUT 20 FEET BEHIND IT. MY FOOT WAS ON THE BRAKE PEDAL THE WHOLE TIME. I CHECKED FOR OBSTRUCTIONS AROUND THE BRAKE PEDAL AND FOUND NONE. AFTERWARD, WHEN I STARTED THE CAR AGAIN, IT DROVE NORMALLY WITHOUT TROUBLE. THERE WAS NO APPARENT DAMAGE TO THE CAR AS A RESULT OF EITHER COLLISION BUT THE GARAGE WALL SUFFERED SOME MINOR DAMAGE.

WE HAD JUST LEFT THE GROCERY STORE, MY WIFE WAS DRIVING, AND LESS THAN A MILE INTO OUR TRIP HOME SOMETHING FAILED BEHIND THE INSTRUMENT PANEL OF THE CAR THAT CAUSED HOT LIQUID (COOLANT?) TO POUR ONTO MY LOWER LEG AND FOOT IN THE PASSENGER SIDE FRONT FOOT WELL. THE VEHICLE HAD ONLY BEEN RUNNING FOR A COUPLE OF MINUTES AND THE COOLANT WASN'T AT ITS FULL OPERATING TEMPERATURE, SO THE BURN WAS NO WORSE THAN A COFFEE SPILL AND DIDN'T CAUSE SIGNIFICANT INJURY. IF THE VEHICLE HAD FULLY WARMED UP AND THE COOLANT WAS 200+ DEGREES, I WOULD HAVE BEEN BURNED VERY BADLY. I JUST WANT GM TO KNOW THAT THIS HAPPENED SO THAT MAYBE THEY CAN PUT SOMETHING IN PLACE TO PREVENT THIS BEFORE SOMEONE GETS SEVERELY BURNED .

POWER TRAIN — Filed 05/22/2017

1. THE VEHICLE ROLL BACKWARDS IN UNPREDICTABLE WAYS EVEN ON SMALL INCLINES WHEN FOOT IS TAKEN OFF THE BRAKES. AT TIMES VEHICLE WILL GO FORWARD AND AT OTHER TIMES IT WILL ROLL BACK ON THE EXACT SLOPE. WE WERE TOLD BY BUICK DEALERS THAT THE MANUFACTURER DOES NOT SEE THIS AS AN ISSUE. HOWEVER, BOTH MY WIFE AND I HAVE BEEN STARTLED ON SEVERAL OCCASIONS IN WAYS THAT WE HAVE NEVER EXPERIENCED BEFORE. WE CONSIDER OURSELVES TO BE VERY SAFE DRIVERS AN HAVE BEEN DRIVING FOR OVER 20 YEARS IN THE US WITH NO ACCIDENT CLAIMS. NONE OF THE VEHICLES WE HAVE OWNED OR DRIVEN HAD BEEN THIS DIFFICULT TO MANEUVER. ON SEVERAL OCCASIONS, WE HAVE COME CLOSE TO HITTING STOPPED VEHICLES BEHIND US AT TRAFFIC SIGNALS. 2. IN ADDITION, REAR VISIBILITY THROUGH THE SMALL WINDOWS IS CHALLENGING WHICH IS FURTHER OBSTRUCTED BY COLUMNS. 3. ALSO, REAR VISIBILITY THROUGH THE REAR VIEW CAMERA IS POOR UNDER NORMAL DAYLIGHT CONDITIONS DUE TO THE POOR RESOLUTION. AS A RESULT OF THE ABOVE POINTS, IT'S VERY UNNERVING WHEN ONE IS CAUGHT ON THE DRIVER SEAT WITH THE VEHICLE MOVING BACKWARDS UNEXPECTEDLY. FINALLY, THE INEVITABLE HAPPENED. THE VEHICLE MET WITH AN ACCIDENT AS A RESULT OF THIS. THE VEHICLE WHICH USUALLY GOES FORWARD WITH FEET OFF ACCELERATOR ON A MILD SLOPED DRIVEWAY IN FRONT OF OUR HOUSE, ROLLED BACKWARDS IN THIS PARTICULAR INSTANCE. THE STARTLED DRIVER ERRED ON THE SIDE OF SAFETY BY PRESSING THE GAS PEDAL TO MOVE THE VEHICLE FORWARD SINCE THERE WERE CHILDREN PLAYING AROUND. HOWEVER, WITH LIMITED ROOM TO MANEUVER, THE VEHICLE ENDED UP HITTING OUR GARAGE DOOR. THE REPAIR HAS BEEN ESTIMATED AT $6000 +. $1500 FOR THE GARAGE DOOR. WE FIRMLY BELIEVE THIS IS A DIRECT RESULT OF THE VEHICLE OPERATIONAL DESIGN. IT HAS NOTHING TO DO WITH OUR DRIVING. WE HAVE NOT HAD A SINGLE INCIDENT IN 20 YEARS OF DRIVING WITH ANY OF THE CARS WE OWNED OR RENTED.
