2020 Jeep Compass Electrical System Problems

Car stalls out when driving. Car also stalls when I dont press the automatic start button.

I tried the auto start on the fob car would not start I tried to the push start nothing again . Did get warning coolant temp high Had to tow car They are investigating

While driving the 2020 Compass a message will s poradically appear on the dashboard display about "High Coolant Temperature" and immediately sends the vehicle power to shut down and after a couple of seconds the error disappears and the temperature returns to normal. It once shut the engine down completely in the middle of the street and I had to put car in park in middle of traffic and then restart it. This happens at all rates of speed - on the highway driving 65 mph or on a city road driving 40 mph. Dates is has happened that I took note of: 09/11/2025, 10/04/2025, 11/01/2025 and 11/17/2025. It has happened previous to 09/11/2025 as well. It is a serious safety issue to loose power while driving.

The contact owns a 2020 Jeep Compass. The contact stated that while operating the vehicle, the infotainment screen began to display a pixilated and distorted image. Due to the failure, the rear-view camera failed to operate while in reverse(R). The failure persisted, and several lines appeared on the infotainment screen before the screen went blank. The vehicle was taken to a dealer, and a diagnostic test was performed. The contact was informed that the radio was defective and needed to be replaced. The manufacturer was notified of the failure on several occasions, and the contact was provided with a case number. The dealer offered to cover half the cost of the repair. The vehicle was not yet repaired. The failure mileage was approximately 54,000.

My engine light kept on coming on esc failure I replaced the aux battery then reg battery then alternator went bad then the u connect is not working at all it will not load the maps on the screen it’s doesn’t recognize my phone I bought this jeep brand new

Two recurring issues that happen at the same time. The auto stop/start feature stops working. Error message "Stop/Start Unavailable Service Stop/Start System" is displayed. If this were to happen at a traffic light, the failure to restart the vehicle could cause accidents. At the same time, the door locks become inoperative in one of several ways. They may not unlock by using the in-car button on the door. At the same time, using the key fob may or may not unlock the door. If you are outside of the vehicle, the key fob may not unlock the doors. If you are in the car when it happens, you may be trapped. That is an obvious safety issue. If you are trying to lock or unlock, using the key fob, from outside the car and the door locks are not responding, your safety can be compromised by not being able to enter the car in a dangerous situation. These issues have been confirmed and reproduced by a Jeep dealer on three different occasions in less than two months. They have replaced both car batteries. The door lock assembly has been replaced three times. The Body Control Module has been replaced three times. The latest failure was on 2/2/2025.

Car won’t start due to Low Coolant error, fluids are fine.

Auto start stop unavailable service Auto start /stop system shows up. It has killed 1 main battery and 2 auxiliary batteries but there is no stored messages so dealership can not figure out the problem.

The (A) this automatically temporarily pause the idling of the engine when stopping at a light or stop sign. I’ve noticed that it’ll shut my car off completely as if the battery has died. I’ve been put in scary situations due to heavy traffic. I’ve held up traffic for at least 3-10 minutes. ( my battery is less than 2-3 yrs old). So, for now I’ve started turning that function off upon starting the car before I put it in gear. Any complaints about that anyone know of?

The screen on the dash has quit working and the backup camera does not work this started when we got snow, thought once weather warmed up things it would work tried the reset button to no avail. Hesitated about buying another jeep now I wish I hadn’t nothing but trouble

Car had high coolant temperature warning come up on dash and car went into limp mode but then just cleared and continued to drive fine. Recently had auxiliary battery replaced due to auto start/stop not working.

Car engine turned off while driving, e brake was activated with out warning. Car stopped, and the D on the shaft was flashing, vehicle placed in park and was turned off by driver. Car would not restart and could not depress the brake. Car was stuck in the middle of road. After several attempts car sputtered on and was able to be driven to a safe location. No warning lights activated on car, initial eye inspection didn’t see anything out of place. No fluid leaking. Battery was operational entire time

The primary issues involve the Powertrain Control Module (PCM), wiring harness, and auxiliary battery system. These interconnected problems compromise vehicle reliability, pose safety risks, and create undue financial burdens on owners. Overview of Defects The vehicle failed to start on [XXX], with illuminated dashboard warnings and automatic parking brake engagement. Initial diagnostics led to replacing the battery and starter, but the issue persisted. Further investigation revealed PCM failure, and even after its replacement, the vehicle remained inoperable. Subsequent diagnostics identified a defective wiring harness. Southern Jeep in Norfolk, Virginia, estimated replacement costs at $4,500. This critical component facilitates communication between the PCM and other systems, and its failure jeopardizes vehicle safety and reliability. Incident History 2021: The vehicle stopped unexpectedly in traffic on Portsmouth Boulevard, Virginia. Initially attributed to a battery failure, evidence now suggests PCM or wiring harness involvement. [XXX]: The vehicle failed to start, initiating weeks of diagnostic efforts and costly repairs. November 2024: The wiring harness was identified as the root cause following PCM replacement. Safety Risks Unexpected Shutdowns: These pose a high risk of accidents, endangering vehicle occupants and other drivers. Start/Stop System Failures: Malfunctions increase the likelihood of breakdowns in hazardous locations. Broader Context Complaints from other Jeep Compass owners and Jeep's issuance of multiple Technical Service Bulletins (TSBs) confirm systemic defects in the start/stop system, PCM, and wiring harness. Despite evidence of these recurring issues, Jeep has not initiated a recall, leaving owners to shoulder repair costs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

car always go to coolant temp high when driving and goes back down to middle mark, i will put antifreeze in the car and it will be okay for about two weeks and starts back up again. i always have to put antifreeze in my car and more frequent when the weather gets warmer.

Overheated warning light came on. Car was filled with coolant and light went off. One week later, light came on again. Brought to an independent service center who did diagnostic testing and could not find a leak or faulty parts. Appointment made with dealer. Light appeared once more, topped off coolant and light did not appear again when brought in to dealer (about a two week period). Dealer did diagnostics and said the engine was “burned out” and needed to be replaced at a cost of $10,000. Faulty electrical/coolant system led to ruined engine.

On several occasions, when idling in traffic, the engine stalls and the parking brake engages. On another occasion when stopping at a stop sign, the parking brake engaged while vehicle engine still on and the steering wheel would not turn, nor would the gas pedal move the car in any direction. On 1/3/24, the vehicle stalled, was cranked up, and would not go faster than 5 mph. The vehicle was turned off, the engine rested for approximately 5 minutes, it cranked and was driven to a Jeep dealership that date. The safety of myself and others was put at risk when sitting in traffic and the engine stalled and parking brake engaged. There have been no warning lamps or messages to indicate any problem with the vehicle. This could have led to serious accidents. The vehicle was dropped at a Jeep dealership two weeks ago (01/03/2024) but it has not been inspected as of yet. When the vehicle parking brake engaged and vehicle would not move in any direction, the police was called to help get the vehicle started. Insurance has also been informed of the issues with the vehicle, and a case has been opened. The last occurrence happened on 1/3/24, and that is the date the vehicle was taken to a Jeep dealership and left with the service department. The issues started approximately two weeks prior, was reported to a Jeep dealership, but the closest dealership had no openings to inspect vehicle. Thus, it was taken to a Jeep dealership over an hour away.

2020 Jeep compass shuts off randomly while driving in traffic and sometimes will not start back up after. Says the coolant temperature is too high but the temperature is fine. Car is a danger to Public safety and is one of many that is experiencing the issue.

At first my car would only display the “Coolant Temp Too High” message if I came to a complete stop, and went again.. or if i would go over a certain speed. At that time, i could pull over, turn it off, wait a few minutes, and turn it back on and i could watch my coolant temp drop drastically.It has progressively gotten worse to the point that i cannot drive the vehicle longer than five minutes without it overheating. I do the same thing, pull off and wait and turn it back on. It starts to go down a bit, however, as soon as i pull out and begin to drive it, it starts to raise back up immediately. There have been times where the message will display as soon as i turn the car on in the morning.. Please help me. I am a young college student and I have not been able to drive my car for over 6 months. We have changed the thermostat, flushed the coolant, checked for leaks, replaced the radiator cap, and water pump. I don’t know what else to do..
