2019 Jeep Wrangler Unlimited engine problems

“On [XXX], my 2019 Jeep Wrangler Unlimited Rubicon (2.0L turbo) caught fire in the engine compartment while driving, at approximately 101,437 miles. The fire started near the turbocharger and heat shield area. There were no injuries, but the vehicle was moving on a public road with four occupants, including two young children in car seats in the rear, when the fire started. The vehicle had been returned to me four days earlier, after approximately 2.5 months at Preferred Chrysler Dodge Jeep of Muskegon, MI for a timing chain replacement. After the fire, I found that the coolant reservoir hose had come off its fitting, and the hose barb appears to have been broken and the hose pushed back on. Several under-hood trim fasteners were also missing. My best assessment is that coolant sprayed onto the hot turbo/exhaust components and ignited. The vehicle has not been altered since the fire and is available for inspection at Watson's in Ludington, MI. I reported the fire to the manufacturer. They directed me to take it to the local dealer, then instructed the dealer not to inspect or work on it. The case was escalated internally, but as of 10/15/2026 no manufacturer…”

“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.”

“VEHICLE & INCIDENT: 2019 Jeep Wrangler JL 2.0L Turbo. While climbing an extended grade on Hwy 87, vehicle experienced a sudden sluggish throttle anomaly and rapid coolant temperature spike from ~215F to 255F under load. Vehicle was pulled off and shut down within ~20 seconds. SUSPECTED FAILURE MODE & UNDERHOOD FIRE: Upon opening the hood, pressurized coolant had sprayed across the engine bay from a split in the smaller rubber hose branch of the engine coolant outlet assembly (Mopar PN 68280797AC). The hose split longitudinally ~13mm with the center ~32mm from the hose end. The vehicle is equipped with a Baja Designs T-Fitting to replace 68280784A The hot, pressurized coolant sprayed directly onto the exposed, center section of the turbocharger between the compressor and turbine sections and on the turbine section itself. The coolant is suspected to have flash-ignited on contact with the turbo, creating an active under hood fire that began spreading to the hood insulation liner. The fire was successfully doused roadside with water, preventing a total vehicle burn-down. No other fuel sources were noted and the lines to the turbocharger were intact and did not…”
