2019 Jeep Wrangler electrical system problems

“voltage regulator chip failure can cause the engine to stall or fail to start completely. Interior dashboard lights and dome lights along w/ windshield wipers going off without prompted happen after vehicle shutoff. Had to jump it to begin to start at times. Similar to recall U87.”

“The contact owns a 2019 Jeep Wrangler. The contact stated that while driving approximately 40 MPH, the instrument panel cluster suddenly went black. The contact pulled to the side of the road and waited for a family member to follow closely behind to ensure a safe drive, as essential driving information was no longer visible. The vehicle was taken to the dealer, where it was diagnosed that the instrument panel cluster had failed and required a complete assembly replacement. The vehicle was pending repair. The contact learned of NHTSA Campaign Number: 24V652000 (Electrical System); however, the vehicle was not covered under the recall because the VIN was not included. The manufacturer was notified and confirmed that the VIN was not included in the recall. The failure mileage was approximately 81,000.”

“While driving my 2019 Jeep Wrangler, the vehicle suffered a major electronic/CAN-network failure. Service Shifter, ABS and ESC warnings appeared, the wipers activated on their own, controls malfunctioned, and power-steering assistance failed while the vehicle was moving, making it extremely difficult to steer. My two young children were in the vehicle. Jeep dealer diagnostics showed widespread communication faults involving steering, ABS/brake, transmission and other control modules. The dealer replaced the power-steering assembly and RF Hub, but the problem remains. On the first drive after repair, the ABS and ESC warnings repeatedly flashed on and off at highway speed. Interior lights are also flickering. I am concerned another network failure could again disable steering assistance or compromise ABS/braking-related safety systems and cause loss of vehicle control or a crash.”

“Vehicle went into dealer for diagnostic, update PCM for hill start assist and cruise control failure. Dealer identified pcm update was not done when clutch recall performed. Instrument cluster update was pushed as well. Instrument cluster bricked. headlight indicator only functioning light on cluster. All gauges and information screen are dark. no functionality. Car has been sitting at the dealership since July 1, 2026 waiting on a replacement instrument cluster.”

“2019 Jeep Wrangler JLU experienced intermittent CAN-C communication failure. Vehicle has repeatedly experienced simultaneous loss of multiple electronic systems. On September 7th 2026, while driving, vehicle unexpectedly lost electric power steering, windshield wipers activated without command, ABS/TPMS/ESC warning lights illuminated, and vehicle subsequently would not shift into gear after stopping at a traffic light. Hazard lights would not activate. After shutting vehicle off, vehicle would not enter ACC or restart normally. Opening driver’s door unexpectedly caused vehicle to enter ACC. Manipulating the CAN-bus wiring/STAR connector behind the glove box has historically temporarily restored normal operation. Vehicle has previously required repair to this wiring/connector, and the failure has recurred. This has been occurring for at least 3 years and since 60,000 miles. This presents a significant safety hazard because steering assistance, shifting/propulsion, and signaling were simultaneously affected while driving. It is a known Chrysler issue (FCA STAR Case S2108000146) and should be recalled as there is a CLEAR and present danger with this ongoing issue.”

“The IPC Cluster completely blank. Unsafe to operate vehicle, as speed was unknown, unable to read fuel gauges, and unable to see any warning lights. Experienced the exact problem noted in Recall Campaign 30B/NHTSA 24-V 652 for jeeps with the 3.5 inch cluster layout, and my VIN is not listed on the recall list.”
