Electrical complaints
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.
Unknown. Vehicle has been inspected prior for electrical issues while under warranty. Dealer claims no issue. Backup camera does not work, vehicle temperature settings are not accessible on screen.
Vehicle shuts off randomly. Restarts after stopping but it's consistent as if the car over heated yet the coolant temperature reads 194-200
Car stalls out when driving. Car also stalls when I dont press the automatic start button.
I've had this car since March 8, 2020 and from the very beginning I've had electrical issues at first. It started with just my lights flickering the dashboard as well and it progressed overtime and also gave my different messages on my dashboard. The radio would shut off making it impossible to use my backup camera as well, I wasn't able to take it to the dealer because when I called they said that it all had to come out of my pocket, even though I had just bought the car so it was a little impossible for me to be...

able to afford that at the moment so I put it all off overtime. It did progress and I had to get the battery switched out twice as well as the second battery this happened while I was pregnant and it actually was because the car stalled out on me. I was out in Palmdale visiting my parents when the car completely turned off all the electrical options were nonexistent. I was at a stoplight and when the car didn't turn back on, it was dark because Palmdale is a desert area. I had no lights, and I had no way of telling the rest of the drivers I was having an emergency if I got out the car, I was putting myself at risk as well as my babies. My car stalling happened a few times over the years which also exposed extended family members. I repeatedly asked Jeep to help me and they have possession of the car at the moment. I still have payments on this car and I have the tags due in two weeks. I've called them and they are giving me the runaround and it's very disheartening and very frustrating. I'm a full-time mom, I work, I go to school and I have a home to run. They never offered for a replacement car or any type of temporary help, they said they would run the diagnostics free of charge and now the dealership wants to charge me as well. I can't afford it after paying a private mechanic for that diagnosis as well. Jeep is unwilling to help me at this point and I need further assistance.
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.

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 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

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?
I was driving down the road going about 40mph. The car stopped abruptly and displayer low coolant warning. Car would not restart. I towed it to a local mechanic who replaced the auxiliary battery. Car has been working and hasn't shut off but warning lights sometimes pop up for a split second. I'm worried it's going to happen again while driving.

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.
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.
My trancontrol started to run hot,and the vehicle started to jerk when it in motion and My driver shaft went bad and the transfer case assembly went outthe jeep compass is broken down
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.
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 [[redacted]], 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. [[redacted]]: 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.

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
This issue has been happening sporadically over the last couple of years, but it's starting to happen more often. When driving normally, the check engine light will flash, a message "Coolant temp too high" will appear in red, and the car turns off. Sometimes it will turn back on immediately and drive fine, other times I have to leave it turned off for up to 2 minutes. This happened to me twice on my drive to drop off my kid at school, and on my way to the office, on a busy highway during traffic. All maintenance...
