  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.

   I have the active recall associated with the vehicle listed. It’s been nearly 2 years with the active abs service light, traction control light, and inoperative cruise control due to those lights. Stelantis is not very helpful. Will not fixit yet. But says I can pay myself and some or all may be reimbursed. There is no reason it should take this long. Endangering lives potentially. I sent truck pulling all the time. And you buy these things with these safety options that…

   I have been waiting on the C4B recall for nearly two years with no parts available still. My truck has no ABS, traction control, or 4WD. This is a 2500 heavy duty truck meant for pulling trailers and heavy payloads. This recall has rendered the vehicle useless. I can't trade it in due to the ongoing recall, it is not safe to drive, I am at an extreme financial loss due to Stellantis' negligence. How has the US government allowed this issue to last for so long? How many…

   The Hydro Boost Pump Port Tube Assembly (Mopar P/N 04581758AA / 4581758AA) on my 2018 Ram 2500 6.7L Cummins has failed and requires replacement. My concern is that this component is part of the hydraulic assist system supporting critical steering/braking functions. A failure or loss of hydraulic pressure could result in significantly increased steering or braking effort and create a serious safety hazard, particularly while towing, carrying a load, or traveling at highway…

   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…

    Vehicle is unsafe to drive due to the loss of ABS and traction control. The constant dinging of the warning is very distracting. Stellantis, Ram Trucks, and local dealers do not seem to care that this has been an ongoing issue for over a year and still do not have any parts for the recall.
