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.

I was stopped at a traffic light and began moving forward to make a turn into traffic. As I activated my turn signal and started to proceed through the intersection, the vehicle suddenly stalled and shut off without warning, causing an immediate loss of power while the vehicle was in motion. Another vehicle was entering the intersection at the same time, creating a near-collision situation. I was forced to restart the vehicle in traffic. The incident occurred within less than 250 miles of purchasing the vehicle. The vehicle had recently received an oil change and inspection. No warning lights or messages were observed prior to the stall. This event created a serious safety risk.

My suv dies while im driving it. The engine stalls the lights go off. Its very dangerous I had a semi truck behind me last night and my encore basically became invisible. No lights no power, nothing. He almost hit me. Ive had this encore to several mechanics and none of them knows what the problem is. There are no warning lights on and it does not show any codes when hooked up to a diagnostic machine. I have called Buick Corp.and she told me to take it to a mechanic.

I've been dealing with a frustrating car issue lately where my vehicle keeps stalling and hesitating during acceleration - whether I'm pulling away from a stop or trying to pick up speed on the road. After getting it checked out, my mechanic determined that the high pressure fuel pump control module is the culprit and needs replacement. The problem is, we're stuck waiting for the part because Buick has it on backorder indefinitely. What's particularly concerning is that GM recently issued a recall for this exact same fuel pump issue on certain models, but somehow my VIN number didn't make the cut. I strongly believe it should have been included, especially considering the safety implications here. When this fuel pump control module fails, it can completely cut off fuel flow to the engine, which creates a serious traffic safety hazard. Nobody wants their car suddenly losing power while merging onto a highway or navigating through an intersection. This isn't just an inconvenience - it's a legitimate safety concern that affects real people on real roads every day.

This included a turbocharger oil return tube, turbocharger oil supply and re, intercooler, int. man. & vAL. COV. Kit, R&R inter cooler, R&R turbocharger, R&R intake manifold, and turbocharger assembly. Since that time, the same problem has recurred and I have returned the vehicle to the same location on four separate occasions without resolution. It is currently available for inspection. •August 11th, 2025: Vehicle stalled in the middle of an intersection as I attempted to accelerate from a stop sign, placing me in immediate danger of collision. •I have had the check engine code read by another independent service center. •No one else has inspected the vehicle •The check engine light has come off and on since January when the problem began after visiting Mavis Discount Tire in sinking spring for a routine oil change. There were no symptoms prior to this first failure that signaled the issue that resulted in the repair. Prior to the incident on August 11th there had been repeated symptoms of an issue even when the check engine light was off.

My daughter owns a 2019 Buick Encore and the check engine light keeps going on. She took her car to the dealer and was told that it needed a Turbo Bypass Valve and Solenoid valve. The car is just a few months within the 10 year powertrain warranty and the dealer refused to cover as defect. She drives on the freeway 45 minutes to/from work and this is a serious issue that causes the engine to rev hard and not stop as well as stall intermittently.
