2018 Chevrolet Equinox: engine failure

Filed Aug 19, 2026 · Engine · WI

While driving, the vehicle experienced a sudden, catastrophic loss of engine power accompanied by severe engine shaking, reduced acceleration, and a lit Check Engine / ESC light. The vehicle was towed to a technician who diagnosed a complete dead misfire in Cylinder 4. Upon detailed inspection, the ground electrode/tip of the spark plug had broken off inside the combustion chamber while the engine was running. The free-floating metal fragment severely gouged the piston crown and scored the cylinder wall, resulting in a total loss of compression and catastrophic engine failure at just under 51,000 miles. This unexpected engine failure causes an immediate and dangerous loss of motive power while operating in traffic, creating a severe crash hazard for passengers and surrounding motorists. This issue appears to stem from a known component defect (GM Technical Bulletins PIP5657C & 21-NA-255) related to premature spark plug failure and low-speed pre-ignition (LSPI) in the 1.5L turbo engine.

While driving the brake pedal suddenly became hard to push making the car unable to slow down. Put car in neutral and managed to get off street into parking lot and coast to a stop. Car would no longer start. Towed to dealership for assessment. Reports of broken vacuum pump pieces and related metal debris found in engine. Dealership recommended engine replacement. Notified GM, they provided a case number and helped discount the full cost of engine replacement down to $6,225.00 which we paid out of pocket (or risk losing the full value of our equity in the vehicle against a replacement).
