2019 Jeep Compass: check engine light

Filed Oct 24, 2026 · Electrical, Lights · OH

I am reporting ongoing safety concerns involving my 2019 Jeep Compass Trailhawk, including unexpected engine shutdowns, repeated battery failures, electrical malfunctions, and recurring check engine warnings despite regular maintenance and multiple repairs. In 2023, the vehicle’s automatic start-stop system malfunctioned, causing the vehicle to shut down completely while I was traveling on the expressway. This created an extremely dangerous situation. The vehicle was towed for inspection, but no problem was identified. After being jump-started, the vehicle operated normally. In September 2024, both the main battery and auxiliary battery were replaced. However, the vehicle continued shutting down and requiring jump-starts. I subsequently took it to the dealership, where wiring connected to the battery system was replaced. The vehicle operated normally for several months following this repair. Since purchasing the vehicle, I have also experienced intermittent electrical malfunctions involving the radio and infotainment system. The radio unexpectedly shorts out, and the display screen goes completely black before eventually restoring itself. Additionally, during each of my last four routine oil changes, the vehicle has died or failed to restart, requiring a jump-start. Approximately one to two weeks after these maintenance visits, the check engine light illuminates. The vehicle has consistently received regular maintenance, yet these problems continue despite battery replacements and dealership repairs. My greatest concern is the possibility of another unexpected engine shutdown while driving, particularly at highway speeds. The 2023 expressway incident placed my safety and the safety of other motorists at risk. I am requesting an investigation into potential defects involving the automatic start-stop system, electrical system, battery management system, and related components. I am also requesting a review of similar complaints, recalls, and manufacturer servic

I own a 2019 Jeep Compass with approximately 72,000 miles. For the past two years, I have experienced intermittent electrical and brake system failures that have become more frequent and severe despite multiple repair attempts. While driving, especially when turning, braking, or driving over potholes or uneven roads, the vehicle suddenly displays multiple warning lights, including ABS, traction control, brake, check engine, and service transmission warnings. At the same time, the digital speedometer changes to "--" and stops displaying vehicle speed. On one occasion, the analog speedometer also dropped unexpectedly. The most serious incident occurred after these warnings appeared while I was driving. I pulled over, shifted into Park, and attempted to turn the vehicle off, but it would not shut down for approximately 30 seconds. During that time, the brake warning light flashed continuously, indicating a possible electrical or communication failure. After restarting, some warnings cleared, but the check engine light remained on. Although the brake pedal still felt normal, I temporarily lost multiple electronic safety systems, including ABS, traction control, and the vehicle speed display. These failures occurred on a public roadway without warning, creating a significant safety risk and reducing my confidence that the vehicle will respond properly during an emergency. A diagnostic scan retrieved multiple communication-related fault codes, including U0002-00 (CAN Bus Off), U0121-00 (Lost Communication with ABS Module), U0129-00 (Lost Communication with Brake System Control Module), U1110 (Lost Vehicle Speed Message), U1120 (Lost Wheel Distance Message), U1141 (Lost Brake and Torque Message), and U12A8 (Lost Communication with Master Cylinder Pressure Sensor). The problem is intermittent, often clears after restarting, and is difficult to diagnose. Because it affects critical safety systems while the vehicle is in motion, I believe this represents a serious safety

Three times since 8/2025 the vehicle flashed a “coolant temperature too high” warning despite the gauge reading normal and no check engine light. Coolant reservoir was at appropriate line. This immediately caused the vehicle to enter limp mode after idling in the drive thru. The vehicle remained in drive with full power but would not allow me to drive or shift to park until i turned the vehicle off. It would restart and allow me to drive. The 4th incident happened 12/13/25. I was at a red light, idling, and when green light came my vehicle flashed the coolant temperature warning and would not allow me to drive. I was stuck in traffic for 5 mins and had to shut my car off to be able to drive. Thankfully in this situation the person behind me was paying attention and did not slam into me. I recently had the main battery replaced. On my way home last night the warning flashed and my car abruptly went into limp Mode while I was actively driving in busy traffic. Thankfully it did not stall and I was able to turn right into a business parking lot. The last two situations could have resulted in accidents and / or injuries and should not be looked over.

On several occasions, the check engine light comes on, the temperature gauge goes all the way up and it states “coolant temperature too high” before the car powers off. I had taken the car to a mechanic who said that it was a sensor issue and replaced the sensor. It has continued to happen on a regular basis while I’m driving. I have contacted Jeep and have an Appointment for them to “assess” the car. This is beyond dangerous, has happened while driving on the highway, and I see that it’s happened to other compass owners as well. Something needs to be done to address this before someone gets killed

The contact owns a 2019 Jeep Compass. The contact stated that while driving on several occasions at various speeds, the vehicle lost power with the check engine and fuel warning lights illuminated. The engine failure, check engine, transmission, engine oil, and alignment messages were displayed. Additionally, the doors locked and unlocked, and the vehicle went into LIMP Mode and then stalled. The vehicle was restarted after 30 minutes, and on the second failure, the vehicle restarted in approximately 10 minutes. The vehicle was towed to a dealer, and the contact was advised to take the vehicle to the Jeep dealer for assistance. The vehicle was then taken to a dealer, where it was diagnosed that there were multiple communication errors and that the software needed to be reprogrammed. The vehicle was repaired, but the failure reoccurred a month later. The vehicle was then taken to an independent mechanic, where the failure could not able to be replicated. The manufacturer was notified of the failure. The failure mileage was 31,586.

Vehicle: 2019 Jeep Compass Mileage (approx): 84,000 miles Issue Type: RANDOM - Electrical failure causing loss of power, brake lock, steering disablement Car is currently at an auto electric shop but can be available if needed. Description of Issue: I’ve been experiencing a recurring and dangerous issue with my 2019 Jeep Compass since around 2021. Every 6–8 months (sometimes more frequently), the vehicle suddenly lights up with every warning signal (check engine, brakes, power steering, airbag, traction, ABS, etc.). The brakes lock up, the power steering shuts down, and the car either dies immediately or will not restart for hours or even days. The issue is completely random and happens whether the car is driving or idling. There’s no apparent correlation with temperature, mileage, or usage. It happens when I'm at a red light, parked and my last incident happen the highway with both my boys in the car. (age [XXX] and [XXX] ) I’ve taken the car to the dealership a couple times, including having it towed in when it would not start. However, by the time they inspect it, the car resets itself, and I’m told they “can’t find the problem.” They’ve held it for weeks without results. This issue is not only unpredictable but highly dangerous. Losing steering and braking while on the road creates serious safety risks for myself, my family, and other drivers. From my own research and symptoms, this could be related to the TIPM or BCM malfunctioning — both of which I’ve read are common in Jeep models. Please investigate this issue, as it appears systemic and unresolved through regular service channels. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving, the Jeep Compass lurched forward several times rather than having smooth acceleration. Within 5 minutes, the vehicle was sputtering and the engine just shut down completely. the "BRAKE" light illuminated on the dashboard, but no check engine light has ever been on. I was able to restart 4 times as I was trying to get to a mechanic. The last time I restarted it was struggling to start. Mechanic has since looked at it, and there are no codes to indicate what is going on. I did notice online that there are other complaints of Jeep Compass shutting off while driving, so I wanted to file a complaint.

Randomly “High Coolant Temp” or “Coolant Temp too high” appears after not driving car for 12+ hours and car won’t start. Check engine light flashes. The Low power light comes on also. Sometimes I can turn ignition button off and right back on and it’ll start with no issues, sometimes I have to hook jumper cables or a jump box to the car to get it to start after the messages appears. Sometimes when it starts after turning off and back on because of the message, idle surges bad and throttle pedal is not responsive. Radio screen becomes unresponsive.
