2020 JEEP COMPASS Electrical System Problems

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...

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.

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

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

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

Coolant temperature warning and sudden engine shutdowns. This has occurred multiple times in 3 months. started when car was at 50K miles. we have been unable to control the vehicle in traffic when this happens. Dealership (Dave Denis jeep-Dayton, Ohio) was unable to find a problem.

The contact owns a 2020 Jeep Compass. The contact stated that the 4WD engaged and disengaged while driving down the road. The contact stated that the brakes locked up while 35 MPH. Additionally, the computer became inoperable. The contact stated that the battery was replaced, but the vehicle failed to charge. The contact stated that the vehicle failed to start. The Service 4WD message was displayed and the Auto START/STOP feature was inoperable. During inclement weather of snow or rain, the 4WD failure was more prevalent. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 97,000.

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.

I had to get my engine replaced a year after I got it. The vehicle has an overheating issue. The vehicle oil pressure sensor goes off. The emergency break comes on. I don’t know where the engine light flashes the EI had to get my engine replaced a year after I got it. The vehicle has a overheating issue. The vehicle oil pressure sensor goes off. The emergency brake comes on. I don’t know where the engine light flashes the ECS light come on the cooling and oil mix together out of nowhere

The contact owned a 2020 Jeep Compass. The contact stated that the navigational screen was black. The contact stated the navigational screen failed to turn on as needed. No warning light was illuminated. The vehicle was not taken to the local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 68,000.

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...

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

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...

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

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 has been done on time, and there are no error codes when I get it scanned. I get met with shrugs and "could try ..." I see others have been having similar issues, so I am going to post here as well.

I was driving home and got an error message that the coolant temperature was too high, even though the gauge showed it to be right in the middle at the normal level. The car then locked up and I was unable to turn the steering wheel for a terrifying few seconds. The car then restarted itself and I was able to drive home. a while later, I tried to start the car and it would not start and kept giving me the error message that the coolant was too high even though the gauge shows the level to be The very bottom of the temperature on the cool side. I checked the coolant levels and they were a little low so I added more coolant up to the max level and waited a few hours. Then I tried to start it again and it still will not start. Additional error...

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...

Yes, I bought a brand new 2020 Jeep Compass North Edition from a Wisconsin dealer in June 2020. I drove across country to Utah where I know reside. Had no problems on that trip. About 10 months later I started experiencing a "High temp coolant" light come on and the vehicle shuts off and locks up. Very dangerous while driving. After about 30 seconds I could restart it. It happened about 10 times. Then another alarm came on stating "Service electronic throttle control." As well as the "High temp coolant" warning. Milage at this time was 21K. Took it to a dealership because of the extended warranty I purchased. They replaced both batteries but could not get it to "error out" again. They also stated that there were no error codes stored in the memory, even though I had pictures of the dash showing the error codes. I could not...

We drove to the grocery store 5 minutes away. After being in the store for about 15 minutes we returned to go home. We tried starting the car and it wouldn’t start, message “High coolant temperature” came on with orange engine light. We waited 5 minutes, started again and all the warning lights flashed and the car locked up. Nothing would engage, even the brakes. We had to abandon the car in the lot and walk home.

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.

The first incident happened with my 2020 jeep Compass on 12/27/23 while on the freeway the temp light flashed the gage didn't indicate overheating I got off the freeway check the engine no sign of overheating waited for awhile then started the car again within five minutes car gage went to overheating had it towed the oil cooler went out out mixed with the coolant paid big bucks for the repairs. I got my jeep back on 1/10/2024 drove it for one week then on 1/16/2024 while driving the dash panel flashed car lost speed even pressing the gas peddle to the floor no acceleration while pulling over the emergency break engaged stoping the car in the road. restarted still no acceleration and car won't move in natural or reveres wheels lock can only move forward at low speed, 01/25/2024 car towed from my mechanic to dealership. Scared to keep...

My 2020 compass keeps shutting off on its own. I will be driving and next thing you know it will start saying "key has left vehicle " or a different message saying a long the lines of its over heating. After the over heating message, the car will completely turn off on me making it hard to steer out of the road. I somehow have yo make it safely out of the way to turn it off and restart it. Im just scared one day it will happen on the highway when cars are going by so fast and ill end up getting in a collision. No solution to the problem. The dealership doesn't know whats going on or even have a clue as to what to look for. This is definitely a safety issue and im upset because no one knows how to fix it. I spent my hard...

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...

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.

The contact owns a 2020 Jeep Compass. The contact stated that while at the traffic light, the auto Stop-Start feature turned off the engine; however, the engine failed to restart. The message "Stop-Start Unavailable" was displayed. The contact restarted the vehicle and manually disengaged the auto Stop-Start feature. The vehicle was taken to the dealer, where the cause of the failure could not be determined. Additionally, the check engine warning light was illuminated. The contact stated while driving 45-50 MPH, the vehicle stalled inadvertently. The message "Coolant Overheating" was displayed. The contact veered to the side of the road, turned off, and restarted the vehicle; however, the failure recurred while driving. The contact stated that the vehicle failed to start the following day. The vehicle was towed to the dealer, where it was diagnosed that the two batteries needed to be replaced. The vehicle was not repaired. The manufacturer was...

Engine consumes oil rapidly. The touchscreen does not work and shuts off after start-up. Without the touchscreen, the rearview camera does not work, making this problem one of safety. Also, you can not turn on or off safety features in the settings mode, since the screen is blank.

When trying to start vehicle it displays a “Service Electrical System” error followed by “Coolant Temperature Too High” my coolant gauge sky rockets red and then returns to a very low level. The vehicle has not overheated and has been parked and cooled off completely before trying to start. It is now causing my vehicle to throw messages saying my back up light, brake light, and blinker lights are out but all lights work as they are intended.

Vehicle states coolant high and check engine light comes on and care will not start.

After a cold start, the car alerted that the coolant temperature was too high and shut off. No issues had occurred before this.

The A symbol continues to appear on the dashboard which indicates a failure in the STOP/START function of the vehicle. the vehicle has under 21,000 miles on it. I just purchased the vehicle a little over 90 days ago. Returned the vehicle to the service center where vehicle was purchased, and was told that it required an out of pocket expense of over $600.00 . The auto-light button switches back to manual on its own.

While at a stoplight the engine stalled and the instrument cluster displayed a "coolant temperature high" message. After restarting the engine the temperature gauge displayed the normal mid temp. This has happened once before when reversing in the driveway at home. This scenario is identical to the open investigation at NHTSA from December 2022.

Engine temporarily shut itself off by itself in the freeway as I was slowing down pressing my brakes because of the cars in front of me in traffic hour. The car flashed a “coolant temperature too high” message then immediately turned itself off for a minute. The engine/coolant temperature gauge was normal the whole time I was driving (in between the cold and the high sign). But even then it flashed that “coolant temperature too high” message and shut itself off right then for a minute after it flashed me that sign. It was over 100 degrees fahrenheit outside and inside the car without ac it was awful. I immediately turn on my four ways but cars still kept coming up behind me even though I could not move my car. The car would not turn on. I changed gears from drive to neutral and then to park. And after...

Unknown as to exact issue. In August 2021, spark plug blew (according to dealer) in the middle of an intersection after the auto “off” and the engine would not turn back on at approximately 8K miles. The spark plug was replaced under warranty. Starting in April 2023, around 31K miles, on two separate occasions after the auto start/stop is in use. It will turn off unexpectedly and without warning after the vehicle has come to a stop. Both times the vehicle could not be turned completely off and restarted for at least one minute. No messages appear on screen. Both issues appear to be related to the Stop/Start feature. Two different dealers have not been able to identify issue.

The vehicle was in motion going 40 MPH when the dashboard displayed high coolant temp. The dashboard continued to flash other warnings such as check engine and oil change required. Then, the emergency brake light was on, engine light, and oil light. This caused the vehicle to lose total power in the accelerator and partial power in the brakes. The event led my vehicle to cause a complete stop in the middle of a highway. To the resolve the issue, I powered off the engine and restarted the vehicle. After powering the vehicle back on, all was normal other than the check engine light was still on, but it did run perfectly fine. Coolant level in reservoir is normal. This instance has taken place on multiple occasions.

Electronic Malfunctions The Jeep completely turn off. Energy lights did not turned on both batteries died. Unable to move the car to “N” to move it out of the freeway. CHP used flares to detour the traffic. Could have been a feral accident due to the electrical turning completely off on the freeway

On 4 occasions, months apart, my 2020 Jeep Compass has given me a dashboard alert stating “coolant temperature too high” and the engine immediately stalls and shuts down. The first 3 times this occurred, the check engine light would come on and the vehicle would not restart and other alerts such as “service 4WD system” and “EBS not available” would display. At no time was the vehicle overheating or the actual coolant temperature above normal operating temperature. After sitting in the middle of an intersection for 5-10 minutes, the vehicle would finally turn on with the check engine light being off and no alerts displayed. The vehicle would then drive like nothing ever happened for a few months. The most recent time this unexpected shutdown occurred, as I slowed to approach a left hand turn the vehicle gave the coolant temperature error and shut down, losing power steering and making...

Compass both battery’s died (dealer diagnosis response) while driving down a intersection. No warning what so ever. Auto turned “off” while been “on” and in motion. Started surging while everything inside and out is turning off and on. Thankfully not enough traffic that day no accident happen. No power steering, very hard breaks. Had to get off and push auto into a parking lot. Towed it to the dealer, problem could not be reproduce. Could not give me an explanation of why it happen. A warning lamp had come up regarding a low auxiliary battery a couple months before. That problem was solved at the dealer. This is the second time something battery related thing has happen. Got some videos of it surging and showing it’s on while it’s not.

This vehicle has a stop/start function to shut off when the vehicle stops and then cut back on when you press the gas. Approximately 2 weeks ago my vehicle started stalling out whenever it stops and you have to put it in park and restart the car. Sometimes it starts back up, sometimes it takes a few minutes. This is EVERY time it stops—- red lights, stop signs, intersections and poses a hazard.

Car showed false high coolant message. And the engine shut off and would not start again

Engine stalling, false overheating reading, battery failing. Radio screen getting stuck with review camera, radio not shutting off after vehicle shuts off, car in park but is not recognized by the system, TIMP issues stop and start function not working properly, losing oil, ESC needs attention. A whole lot of headache. Car has been broke down for a month with 27000 miles and making payment unable to drive.

Vehicle started indicating High Coolant temperature then engine would shut down. It would restart after shut off. Radio would fade in an out . While vehicle was in motion the engine should shut down and had to pull over and restart the vehicle. This happened on several occasions before the vehicle completely shut down. Towed vehicle to dealership with a repair of $700 to replace both batteries.

Stopped at red light and coolant over heating warning came on screen and vehicle would not move. Powered vehicle down and back up and engine was revving aggressively. Turned vehicle back on after a few minutes and it was fine like nothing happened. At no point was the vehicle actually overheating.

Electrical transmission problem. Car stopped working in the middle of street almost got in accident. Won’t accelerate over 20 miles. Problem turning on after turns off automatically. Seen so many people with this problem. This car needs to be investigated is not safe.

The vehicle has 44k miles on it. Upon starting the car in my driveway today it would not start and was throwing an ECM error code along with "engine coolant temperature too hot". The vehicle fluids levels are perfect but it just will not start. I called the dealership and was advised they've seen lots of these issues but have no clue how to fix the problem. The car will automatically shut down if being driven and this occurs (we read other blogs on this issue) and it is truly a hazard.
