2020 Jeep CompassRecalls, problems, MPG & safety

“My 2020 Jeep Compass experiences sudden, unexpected engine shut-offs while driving. The engine loses power and stalls without warning, and shortly afterward the dashboard displays a 'Coolant Temperature Too High' warning. The vehicle has stalled while in motion, including at highway speeds, creating a serious safety hazard. After the stall, the vehicle restarts and behaves normally, but the problem has recurred multiple times. This matches the engine-stalling and coolant-temperature issue described in the NHTSA investigation of 2019–2020 Jeep Compass vehicles equipped with the 2.4-liter Tigershark engine.”

“I drove myself and my passenger to our destination without issue. After the vehicle was parked for approximately three hours, I started it and drove toward the exit lane leading to the main road. I stopped completely before exiting and was traveling approximately 10 mph as I crossed toward the leftmost turning lane. Suddenly, the dashboard displayed a “High Coolant Temperature” warning, the check engine light illuminated, and the accelerator pedal became resistant/unresponsive. The vehicle slowed to a stop and the engine completely shut off. Without me shifting the transmission out of Drive or selecting Reverse, the vehicle then began rolling backward on its own. The road was not inclined or sloped. The brake pedal and steering wheel became extremely hard to operate. I had no choice but to allow the vehicle to roll backward into the exit lane. I was extremely concerned that it could cause a collision or strike a pedestrian or building, seriously injuring myself, my passenger, or others. The vehicle eventually stopped, but it was left partially in the exit lane and partially in the main roadway. I was in the right-turn lane, and approaching traffic could not…”

“The contact owns a 2020 Jeep Compass. While driving for 5–10 minutes at an undisclosed speed, the vehicle lost motive power with several unknown warning lights illuminated, and a "Pressure Overheating" message was displayed. The Automatic Emergency Braking feature activated. The contact called roadside assistance and had the vehicle towed to an independent mechanic, who replaced the valve cover gasket, spark plug, and battery. The failure persisted. The vehicle was turned off and restarted. The vehicle was taken to a second independent mechanic, who checked the cooling system, performed a coolant test, and completed an oil change. The failure recurred, and the vehicle was towed back to the mechanic, who flushed the coolant and replaced the coolant hose, radiator hose, and coolant reservoir tank. The failure continued with a collapsed radiator hose. The contact had a friend purchase a main radiator hose for replacement. The vehicle was taken to a third independent mechanic; however, no diagnostic trouble code was retrieved, and the cause of the failure could not be determined. The contact was informed that the engine and transmission might need to be replaced.…”
