NHTSA campaign 18V332000 · reported May 17, 2018 · Chrysler (FCA US LLC) · 4,815,661 vehicles potentially affected
- The 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.
- The 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.
- The 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.
Service brakes, hydraulic: foundation components, hoses, lines/piping, and fittings
NHTSA campaign 18V277000 · reported May 1, 2018 · Chrysler (FCA US LLC) · 2,457 vehicles potentially affected
- The problem
- Chrysler (FCA US LLC) is recalling certain 2018 RAM 4500 and 5500 cab chassis trucks. The primary and secondary brake hoses located between the brake master cylinder and the hydraulic control unit may have been manufactured without anti-corrosion plating on the ferrules, which can allow the ferrules to corrode.
- The risk
- If the ferrules corrode, the brake fluid may leak and cause a loss of braking, increasing the risk of a crash.
- The fix
- Chrysler will notify owners, and dealers will inspect the brake hoses and replace them if necessary, free of charge. The recall began June 19, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U41.
Power train: automatic transmission
NHTSA campaign 18V100000 · reported February 8, 2018 · Chrysler (FCA US LLC) · 180,462 vehicles potentially affected
- The problem
- Chrysler (FCA US LLC) is recalling certain 2017-2018 RAM 1500, 2500, 3500, 3500 Cab Chassis, 4500 Cab Chassis, and 5500 Cab Chassis vehicles, all equipped with a column shifter. Pushing the brake pedal for prolonged periods when the vehicle is running and in PARK may cause the Brake Transmission Shift Interlock (BTSI) pin to stick in the open position. With the pin in the open position, the transmission can be shifted out of PARK into any gear without pushing the brake pedal or having the key in the ignition.
- The risk
- Being able to shift the transmission without pushing the brake pedal and/or without a key in the ignition can increase the risk of an unintended vehicle rollaway that may result in personal injury or a crash.
- The fix
- Chrysler will notify owners and dealers will update the Body Control Module software. Dealers will also test the BTSI operation, replacing the solenoid as necessary. The recall began February 26, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is U11.
