2020 Jeep Compass

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 easily see my hazard lights due to the vehicle’s position. I exited the vehicle and opened the hood to signal that the vehicle was disabled. I attempted to shift into Neutral so the vehicle could be moved out of the roadway, but the emergency brake switch would not disengage. The only warning displayed before the incident was “Oil Change Required,” which had appeared approximately three weeks earlier. The vehicle was towed to the dealership. I have previously had similar breakdowns, and each time I was told the auxiliary battery had failed. After this incident, the dealership again stated that the auxiliary battery was the cause. I am skeptical that this adequately explains the vehicle rolling backward while still in Drive. I am reporting this incident so the underlying cause can be investigated.

Within the first month of ownership I began hearing a noise from the right front of the vehicle consistent with a brake or suspension issue. I reported this to the selling dealer repeatedly during that first month; it was not resolved. The noise continued and worsened over the following year, eventually also affecting the right rear. At approximately 20,000 miles, an independent licensed inspection mechanic found that the right front inner tie rod required replacement due to significant wear, and the right rear wheel bearing also required replacement. The vehicle failed state safety inspection as a result of these findings. The mechanic noted the repair scope required disassembly of the steering column, indicating a defect beyond routine wear for the vehicle's age/mileage. Given that these are safety-critical steering and wheel components, the vehicle has been taken off the road entirely pending repair, out of concern that continued driving could result in loss of steering control. The vehicle is available for inspection upon request. A written statement from the inspecting mechanic documenting these findings is available.

The transmission cooling system failed causing immediate failure of the transmission. The vehicle has less than 60k miles and is still covered by the manufacturer powertrain warranty. Dash lights for service engine and service transmission only came on at the immediate time of failure (10 min prior to full transmission failure). No issues were noted in the vehicles prior service 7 months prior to failure. The dealer has confirmed the cause of transmission failure is due to failure of the cooling system.

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.

While turning out of a parking lot, onto a side street, a suspension component failed without warning, causing the front axle to pull out of the transmission. The vehicle immediately became unsafe, as I was unable to turn the wheel (it wasn't connected) to get me out of the middle of the road. This was a sudden, catastrophic mechanical failure with no prior warning lights, messages, or symptoms. It had to be towed. I called a corporate phone number, to create a case number, and heard back from Jeep Autonation immediately. The gentleman who spoke to me, was extremely rude, and told me this was a normal wear and tear situation, and just to "bring it in so they could get to fixing it." I believe a full diagnostic report is necessary, and I'd like to know WHY this failed. I was on the highway just earlier the morning that this happened. THIS IS A SERIOUS ISSUE, to which I'm not getting any traction on. Unfortunately, it needs to be towed there, and I was told the tow would be $100, which I won't be paying, as this was a safety failure. I have also been renting a car for the last three weeks, when this happened. I'm out $1200 for that, and still have no answers. This failure created a significant safety risk to me and other drivers on the road. I am filing this report because the dealership and manufacturer have been unresponsive, and I am concerned this may be a defect that could affect other vehicles.

We have been without our 2020 JEEP since the end of February 2026 due to an engine issue (had the car only 6-7 months). The first company thought there might be coolant in the head gasket causing the issue. After our extended warranty company wanted the engine opened to confirm, we had to send the car to Precision Tune at the end of March to do this (prior place didn't open engines or repair them and recommended Precision Tune). Based on the engine codes of P0301 and P1061, as well how the car started, Precision Tune knew that the multi air actuator had failed. We both kept asking the extended warranty company how opening the engine would tell them that the multi air actuator failed (Precision Tune and JEEP dealer both said it would not show them that). 5 days later the extended warranty company said that the part was not covered. By that time the multi air actuator was on backorder. On April 10, I called up JEEP to ask about the part and when it might be back in stock. I was told that JEEP is doing an engineering review on the part because of the various issues and until that is resolved there is no timetable on when the part will be available leaving customers without a vehicle. This may not seem like something the NHTSA cares about but there is defiantly an issue. In fact, there was a case investigated by the NHTSA about this issue that was closed in 2023. It seems like the issue was never resolved by JEEP and is continuing to the point that the part has to go back through engineering.

At approximately 35,900 miles, vehicle failed a block test indicating combustion gases in the cooling system. Cylinder head gasket was replaced, cylinder head was machined, and exhaust valves were replaced at an independent shop at a cost of over $5,000. Shortly after, at approximately 36,300 miles, vehicle was towed in with sudden loss of power and would not accelerate. Diagnostic codes P1064 (cylinder 4 oil supply solenoid stuck), P0171 (fuel system lean), and P0304 (cylinder misfire) were found. The MultiAir/VVT actuator was confirmed to have an internal failure. Both the independent shop and a Jeep dealership parts department confirmed the component was on indefinite national backorder due to high demand caused by widespread failures of this part. At approximately 37,500 miles, vehicle failed a second block test. The cylinder head was found warped again and required a second full replacement along with motor mount replacement. The vehicle has had its cylinder head replaced twice in under seven months. Total out-of-pocket repair costs exceed $8,000. The sudden loss of power while driving created an unsafe condition. The failure has been confirmed and documented by both an independent repair facility and an authorized Jeep dealership. Check engine light was present prior to each failure event.
