2017 Jeep Grand Cherokee engine problems

On November 23, 2025, I was driving approximately 60 mph in the middle lane of I-495 near Exit 62 in Marlborough, Massachusetts, with a passenger in the vehicle. I signaled to change lanes to pass a slower vehicle, selected Sport Mode, and accelerated. The engine RPM increased sharply and, almost immediately, I heard an extremely loud bang from the engine area. Multiple warning lights began flashing on the instrument panel, the vehicle made abnormal noises, and the engine lost power. The loss of propulsion was immediate while I was traveling at highway speed. Because that section of I-495 slopes slightly downhill and I was already close to Exit 62, the vehicle's momentum allowed me to reach the exit and pull onto the shoulder. Had this occurred in heavier traffic or in a location without a safe shoulder or exit nearby, the sudden loss of propulsion could have resulted in a collision. The vehicle became inoperable and required towing. It was later inspected by an authorized Jeep dealership. The dealer documented a hole in the side of the engine with engine fluid leaking out and determined that the engine requires replacement. The vehicle had approximately 94,298 miles at the time of the incident and had been regularly maintained. The same vehicle had previously experienced a significant engine problem in 2023 at approximately 67,987 miles, involving white smoke, a head gasket leak affecting cylinder 5, and replacement of the cylinder head. I am reporting this because the catastrophic engine failure caused a sudden and complete loss of propulsion at highway speed. The vehicle and failed engine remain available for inspection.

I was stopped at a red light and when it turned green and I proceeded to drive, my car started to hesitate and quit moving right in the middle of the road. I finally got it to the side of the road. When I attempted to reverse it hesitated again and the R symbol started flashing and the engine light came on. The engine codes are P1D97 Clutch A or D defective and P1DB8 Unintended Torque applied while in neutral. Now it's not even drivable.
