There are 7 owner-reported powertrain & transmission complaints for the 2015 Buick Encorein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2015 Buick Encore. The contact stated that the vehicle was sputtering and jerking while attempting to accelerate while driving at various speeds, and while the vehicle was idling. The check engine warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed that the catalytic converter had failed and needed to be replaced. The vehicle had not been repaired. The manufacturer was informed about the failure and confirmed there were no recalls on the VIN. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 86,600.
The turbocharger on my car is failing and had a verified check engine light code PO299. The car is a 2015 with low miles, only 53k. This is an obvious manufacturer defect/defective product with an estimated cost of $1500.00 to replace, according to an ASE independent auto shop I use for all my vehicles. The car is unfortunately not under any warranty anymore, to my knowledge. There is no recall on this part but online on Buick forums and other credible sites, you will find owners of the same exact car reporting independently, the same failing part issues. I am the second owner of this car and bought it used in 2021 from Carmax. Since then, I have spent $$$ to fix random necessary repairs that are defects of the car but not on recall. Recently, the ac went out and that was over $500 alone. Prior to that an 02 sensor and sparkplug went out, etc. I want GM to reimburse me for the repair cost of the failing turbocharger on this low mileage vehicle as it is without a doubt, a manufacturer defect needing repair to prevent the engine from failure and a total loss! I contacted a GM/Buick agent and formal complaint and request for reimbursement. I am now waiting for up to two days for a "senior agent," to contact me back and discuss further options, if any. Until then, I am without a car with two kids at home and this defect is unsafe and a financial burden to me and my family. This is a known issue on this vehicle model and should be covered under a recall from GM!
I've had my car for 3 years. I've always kept up with it's maintenance. My engine/head gasket are blown and I found out this is a common issue with this car. The airbags also dont recognize when there are passengers in the car. I started my car up one morning in September and all of my lights started flashing. I immediately turned it off and towed it to my mechanic to find out that it pretty much has everything wrong with it. My car is barely above 80k
I'VE HAD MY ENCORE FOR ALMOST 2 YEARS. IT IS A 2015 AND JUST UNDER 50000 MILES. FOR THE LAST MONTH ITS BEEN SAYING AWD OFF. THIS IS AS SOON AS THE CAR STARTS. IT ALSO DIBGS AND COMES UP AGAIN EVERY 10 MINUTES WHILE DRIVING. I'VE.CONSULTED THE MANUAL AND IT SAYS OVERHEATING AND TO TURN BACK ON. THIS DOES NOTHING. IT'S BEEN ICY HERE AND I'M STARTING TO FEEL UNSAFE. I DON'T KNOW WHAT.TO DO. I CANT SHELL OUT HUNDREDS TO HAVE IT LOOKED AT.AND HAVE SOMEONE NOT BE ABLE TO FIX IT.
DRIVING CAR LOCKS UP CHECK ENGINE LIGHT COMES ON SAYS CHECK POWER STEERING, WE AIMED TO SIDE OF THE SHOULDER CAR DIES WOULDN'T START.WE HAD TO WAIT ON SIDE OF A INTERSTATE FOR 3 HOURS TO GET A TOW TRUCK, VERY DANGEROUS
TL* THE CONTACT OWNS A 2015 BUICK ENCORE. THE CONTACT STATED THAT WHILE STOPPED ON AN INCLINE, THE TRANSMISSION SLIPPED OUT OF GEAR AND ROLLED BACKWARDS AFTER RELEASING THE BRAKE PEDAL. THERE WAS NO WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO LOVE BUICK GMC (736 SATURN PKWY, COLUMBIA, SC 29212) AND THE CONTACT WAS INFORMED THAT THE FAILURE WAS A KNOWN ISSUE HOWEVER, THERE WAS NO RECALL ON THE VIN FOR THE FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT YET REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 20,000.
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.
