Consumer Description

September 2025; the fuel control module failed at 75 mph in the left lane of I-45 requiring me to pull over on the shoulder in heavy traffic. I eas towed to my dealership 170 miles. At that time the recall test was performed on my 6.2 L L87 engine and passed inspection. The oil was upgraded at that time. Jan. 3, 2026 at 65 mph the engine died, once again on the highway at over 65 mph. Again I struggled to get to the right shoulder in heavy traffic. At the moment of failure, the engine revved from 1500 rpm to 3900 rpm and instantly fell to zero rpm and died. A message on the dash read unable to put in vehicle neutral. Again, I had it towed to my dealership where it's been diagnosed with a seized engine and I'm waiting (three weeks so far) on an engine replacement. I'm told the manufacturer rep has been to the dealership to confirm the failure and approved a complete engine replacement. There was never any advanced warning appearing on the dash. I have thorough maintenance records on this vehicle.
