2019 Jeep Compass electrical system problems

“Start/stop unavailable, pull over safely. Replaced both batteries, still got messages, now being told alternator or pcm needs to be replaced. This has been a constant problem. Ive replaced batteries twice now in less than 3 years”

“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…”

“After making a stop at a stop light the start/stop feature turned the vehicle off. When releasing the break instead of the car restarting, the vehicle stalled and applied the parking break.”

“The central Uconnect infotainment display completely failed, went black, and is entirely inoperable. Because the screen is dead, the rear backup camera fails to display an image when the vehicle is shifted into Reverse. This creates a severe safety hazard, drastically reduces rearward visibility, and places the vehicle in direct violation of Federal Motor Vehicle Safety Standard No. 111 (FMVSS 111) regarding mandated rear visibility.Furthermore, this total hardware failure completely locks out access to all internal vehicle safety, climate, and driving settings that are exclusively controlled via the touchscreen. The system failed prematurely roughly one year after purchase under normal operating conditions. This issue mirrors the symptoms of major backup camera recalls issued by Stellantis for newer model years, but my 2019 VIN is currently excluded. The manufacturer has quoted over $2,000 to repair this known component defect, which consumer data shows is linked to inadequate internal thermal management and overheating design flaws. I am filing this report to urge the NHTSA to investigate and mandate an expansion of the backup camera recall to include…”

“While driving through a tunnel in Boston, MA, the vehicle shut off completely without warning and could not be restarted. The dashboard displayed multiple warning lights and the engine would not crank (clicking sound only). I was stranded inside an active tunnel in live traffic, requiring a Massachusetts State Police response and a tow. The dealer diagnosed a shorted starter, and during the same repair found the radiator leaking from its lower corner seam with no coolant remaining in the system (dealer repair order 316800, at 66,453 miles). An independent repair shop had documented dried coolant residue under the radiator three months earlier at 63,656 miles, indicating the leak had been developing. This vehicle also has a history of auxiliary battery failures affecting the stop/start system: the auxiliary battery failed at 22,517 miles and was replaced under warranty, and failed again at 58,094 miles. A sudden engine shutdown in a tunnel with no ability to restart is a serious safety hazard, and I am filing this complaint to document the failure. Repair invoices are available and can be uploaded.”

“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…”
