2021 Jeep Compass: sudden loss of power

Filed Oct 31, 2026 · Engine · FL

On October 30, 2026, my 2021 Jeep Compass Limited, with approximately 67,000 miles, unexpectedly became inoperable despite operating normally the previous day. When attempting to start the vehicle, the dashboard displayed a “Coolant Temperature High” warning accompanied by a flashing check-engine light. The engine made clicking noises but failed to start, while the radio and other electrical components remained functional. The temperature gauge remained at its lowest reading, and there were no visible signs of overheating, smoke, or unusual odors. The battery and alternator were tested and found to be functioning properly, and diagnostic trouble code U0402 was identified. I am concerned because the federal safety agency previously investigated similar coolant temperature warnings, engine shutdowns, and failure-to-restart incidents involving 2019–2020 Jeep Compass vehicles under investigation PE22-013. Although my vehicle is a 2021 model, it is exhibiting similar symptoms, raising concerns about a potential recurring safety-related defect. An unexpected loss of engine power while driving could create a serious collision risk. I am requesting that the federal safety agency investigate whether the 2021 Jeep Compass is affected by a similar defect and determine whether a safety recall or manufacturer corrective action is warranted.

The contact owns a 2021 Jeep Compass. The contact stated that while driving 75 MPH, the vehicle unexpectedly stalled in the middle of the highway. The vehicle lost power, but was able to be restarted, and the vehicle drove in LIMP Mode to the dealer. The "D" on the instrument panel was flashing during failure, and there was an electrical odor inside the vehicle. The failure was a recurring failure. The dealer was unable to reproduce failure but serviced the auxiliary battery and reprogrammed the transmission; however, the failure persisted. The failure mileage was approximately 86,000.

I am filing a safety complaint regarding my 2021 Jeep Compass Limited due to repeated coolant loss, overheating/high-temperature warnings, and eventual engine failure. The vehicle began losing coolant and required frequent refilling. The problem progressively worsened until coolant would immediately leak out underneath the vehicle when added. I paid approximately $1,400 to have the radiator replaced, but the same problem returned approximately two weeks later. The vehicle subsequently developed additional problems including shaking, a check-engine light, Cylinder 1 misfire, and diagnostic code P0117 related to the coolant temperature sensor/circuit. The vehicle also displayed a warning that the oil temperature was too high and the engine needed to cool down. The vehicle eventually became undrivable, and I believe the engine may have locked up. The progression from severe coolant loss and overheating to misfire, high-temperature warnings, and possible catastrophic engine failure is concerning. This vehicle is used to transport my children, including daily school transportation. I am concerned that a sudden loss of coolant, overheating, loss of power, or engine failure while driving could create a serious safety hazard. The radiator replacement did not resolve the underlying problem, which makes me concerned there may be a larger defect involving the cooling system, temperature control, or related engine components. I am requesting that the federal safety agency investigate whether similar coolant-loss, overheating, temperature-warning, and engine-failure problems are occurring in 2021 Jeep Compass vehicles and whether a safety defect may exist.

To Whom It May Concern: I am writing to formally submit a complaint regarding my 2021 Jeep Compass, particularly concerning recurring mechanical, electrical, and safety-related problems that have created serious concerns about the vehicle's reliability and safe operation. The most concerning issue is the vehicle's unexpected stalling at low speeds, particularly associated with the 2.4L engine. Unexpected loss of power while driving at low speeds creates a significant safety concern because it can occur when entering intersections, turning, maneuvering through traffic, or attempting to accelerate from a stopped or slow-moving position. In addition to the stalling issue, I have experienced or am concerned about the following problems: 1. Transmission Problems The vehicle has demonstrated concerning transmission behavior, including: Rough or abnormal shifting Delayed acceleration Delayed engagement Unresponsive or delayed gear changes Hesitation when attempting to accelerate Behavior that may contribute to the vehicle unexpectedly losing power or momentum These symptoms raise concerns regarding the transmission's proper operation and the possibility that transmission performance may be contributing to the vehicle's stalling and delayed acceleration. 2. Electrical System Problems The vehicle has also experienced significant electrical concerns, including: Infotainment screen freezing or becoming unresponsive Battery becoming completely or significantly discharged after sitting overnight Suspected parasitic battery drain Random or unexplained dashboard warning lights Electrical/electronic systems intermittently malfunctioning These issues are particularly concerning because intermittent electrical problems can be difficult to diagnose and may affect other vehicle systems, including safety-related components. 3. Backup Camera and Safety Concerns I am also concerned about failures involving the vehicle's backup camera and safety-related wiring, including poten

I been having a problem as I noticed it’s been seen multiple times with a jeep compass well mine is a 2021 jeep compass trail hawk. The car will shut off and say high coolant temp when that’s not the problem. The car is not hot and there is no problem with it just lose power and have no control over the car. It shuts off when I’m driving on the highway has left me stranded multiple times. Almost got hit turning on to the highway and it died as I was turning with a car head on. This is so unsafe. The car has been in the shop multiple times they replace stuff say it’s fixed it’s not and happens the minute I drive off. I been stuck in the middle of the lane with oncoming traffic’s and almost been hit. The dealership seams to not know what’s wrong with it and it’s so unsafe to be driving around in. Along with the many other people who have had the same problem. This is dangerous and keep should not be selling unsafe cars.

When stopped at a stop sign (on a slight incline, if that could be a factor), the Compass suddenly lost power. No reaction from pressing the gas pedal at all. In Drive or in Reverse. The Check Engine light came on and the temperature gauge went all the way up. Putting it in Park and restarting cleared the Check Engine light and the temperature gauge was right back to normal. Almost like nothing had happened. Thankfully it was a small intersection with no other traffic. But could this happen on the freeway?
