Electrical system

30 reports1 fire
“The contact owns a 2015 Buick Encore. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal. In addition, the steering wheel seized. The traction control warning light and the power steering warning light was illuminated, and the message to “Contact Dealer for Service” was displayed. The vehicle was towed to the dealer where it was diagnosed that one of the wiring harnesses connected with the CPU had failed. The wiring harness in the CPU was replaced. After the repair, while driving 60 MPH, the failure reoccurred and the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the steering wheel seized. The vehicle was driven to the dealer to be diagnosed; however, the vehicle remained at the dealer unrepaired. The contact related the failure to NHTSA Campaign Number: 15V146000 (Steering). The manufacturer was not made aware of the failure. The failure mileage was approximately 138,000.”

Engine

29 reports
“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.”

“While driving the dash signal came on stating that the power steering unit had gone off. The car was being driven without power steering. The message state to get serviced immediately. There was a recall for this problem but research states that my vin number did not show my car was part of this recall. WELL, IT IS HAVING THE SAME ISSUE AS OTHERS. Please advise as to how I can get this fixed by the dealership under a recall #15168/15U14600. There is only 18,000 miles on this car, YES eighteen thousand. This recall needs to include my vehicle. Please respond immediately.”

Power train

11 reports1 crash
“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.”
