  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.

  Remedy: 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.

   The truck is under recall C4b for the ABS / Traction control system, which also disables the cruise control. I have called several times and had the vehicle into local dealerships and was told there is still no fix. I asked about trading in the truck and the dealers offered me way below KBB value stating they don't want the truck because of the recall. I ask Ram to help me out and they said there is nothing they can do. 3 times now in over the almost 2 years this truck has…

   I haven’t experienced an issue yet. A safety recall was finally issued to my 2018 Ram 2500 pickup truck in 2024. I had taken it to the local Ram dealership (Rairdon’s Ram, Bellingham, WA). On two separate occasions for my truck throwing the following warning light, “Check Electronic Braking System”. At the same time, traction control is deactivated, and cruiser control turns off, so if you have cruise control set, the warning light causes the cruise control to deactivate,…

   My family and I tow a 45 foot RV Toy Howler Fifth Wheel with the truck and the ABS and Traction control lights keep coming on. The RAM Dealer (Aventura) has been telling me for over a year that the parts are on back-order. I've tried to trade it in but the trade in offers have been very low since they know there's no repair parts. I'm very concerned about our safety since we take long trips into the mountains and this is constantly going on.

    The electronic throttle control light and check engine light are on. I took it to a mechanic and had the accelerator pedal replaced. The lights remained on and the truck remains in "limp mode" and will not go over 59mph. The mechanic stated that this is due to the unresolved recall problems with the traction control and anti lock braking system, and the HCU needing replaced. These components and labor are over 2-3 thousand dollars! I have called NHTSA and the manufacturer…
