When owners reported it
Related recalls (3)
Electrical system: instrument cluster/panel
Problem: Chrysler (FCA US, LLC) is recalling certain 2020-2024 Jeep Gladiator and 2018-2024 Jeep Wrangler vehicles. The instrument panel cluster may experience an internal short circuit and fail. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 101, "Controls and Displays."
Risk: An instrument panel that fails to display critical safety information, such as the speedometer or warning lights, can increase the risk of a crash.
Fix: Dealers will replace the instrument panel cluster, free of charge. Owner notification letters were mailed between October 3, 2024, and January 23, 2025. Owners may contact FCA customer service at 1-800-853-1403. FCA's number for this recall is 30B.
Electrical system:wiring:front underhood
Problem: Chrysler (FCA US LLC) is recalling certain 2018 Jeep Renegade, Compass and Grand Cherokee, RAM 1500 and Promaster, Fiat 500x, Dodge Journey, Challenger, Charger and Durango and Chrysler 300x vehicles, 2017-2018 Jeep Wrangler, Dodge Grand Caravan and Chrysler Town and Country vehicles and 2018-2019 Jeep Cherokee and 2018 Chrysler Pacifica and Pacifica Hybrid vehicles. The powertrain control module may be equipped with a voltage regulator chip in the circuit board that may fail, causing a stall or a no start condition.
Risk: A vehicle stall can increase the risk of a crash.
Fix: Chrysler will notify owners, and dealers will replace the powertrain control module, free of charge. The recall began October 2, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U87.
Electrical system:software; vehicle speed control:cruise control; electrical system:wiring
Problem: Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.
Risk: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.
Fix: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.
