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. 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. Note: Owners are advised to stop using cruise control until the software update has been performed.

6L engine and a 160 amp alternator. In the affected vehicles, the alternator may suddenly fail. If the alternator fails, the vehicle may stall without warning, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace the alternator, free of charge.

The supercharger mounting bracket may contact and damage the ABS line, possibly resulting in a brake fluid leak. A brake fluid leak may lengthen the distance needed to stop the vehicle, increasing the risk of a crash.

Fix: ATI will notify owners and will replace the supercharger brackets, free of charge.

The affected vehicles had brake booster shields installed under a previous campaign to prevent water from entering the brake booster and limiting braking ability. This recall is to verify that the brake booster shield installation was performed properly. If the brake booster shield was not installed properly, the vehicle's braking ability may be reduced, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will inspect the brake booster shield, correcting the installation as necessary, free of charge.

The affected vehicles have electro-hydraulic power steering (EHPS) and are equipped with a 5.7L or a 3.6L engine and a 160, 180 or 220 amp alternator. In the affected vehicles, the alternator may suddenly fail. If the alternator fails, the vehicle may stall without warning, increasing the risk of a crash. There is also the possibility that the alternator may short circuit, increasing the risk of a fire.

Fix: Chrysler will notify owners, and dealers will inspect the alternator and depending on the part number, will replace the alternator, if necessary, free of charge.

The affected vehicles, equipped with an eight-speed automatic transmission and a monostable gear selector, may not adequately warn the driver when driver's door is opened and the vehicle is not in PARK, allowing them to exit the vehicle while the vehicle is still in gear. Drivers thinking that their vehicle's transmission is in the PARK position may be struck by the vehicle and injured if they attempt to get out of the vehicle while the engine is running and the parking brake is not engaged.

Fix: Chrysler will notify owners, and dealers will update the vehicle software to mitigate the risk of vehicle rollaway, free of charge. Note: On October 19, 2016 Chrysler identified some previously repaired vehicles did not receive the complete software updates.

The affected vehicles are equipped with radios that have software vulnerabilities that can allow third-party access to certain networked vehicle control systems. Exploitation of the software vulnerability may result in unauthorized remote modification and control of certain vehicle systems, increasing the risk of a crash.

Fix: Chrysler will notify and mail affected owners a USB drive that includes a software update that eliminates the vulnerability, free of charge. Optionally, owners may download the update to their own USB drive from http://www.driveuconnect.com/software-update/ or take their vehicle to a Chrysler dealer for immediate installation.

Due to a fault within the Occupant Restraint Control (OCR) module, the frontal air bags, seat belt pretensioners, and side air bags may be disabled. The malfunction indicator light “MIL” should illuminate to initially warn drivers of a failure. If the frontal air bags, seat belt pretensioners, and side air bags are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates use of the passive restraint system.

Fix: Chrysler will notify owners, and dealers will replace the ORC module, free of charge.

Due to an issue with the software for the Steering Column Control Module (SCCM), the Electronic Stability Control (ESC) may be disabled. If the ESC is disabled during certain driving situations, the driver may not be able to adequately control the vehicle, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will update the SCCM software, free of charge.

6L engine and a 160 amp alternator. In the affected vehicles, the alternator may suddenly fail. If the alternator fails, the vehicle may stall without warning, increasing the risk of a crash.

Fix: Chrysler has notified owners, and dealers will replace the alternator, free of charge.

In the affected vehicles, the wiring for the vanity lamp in the sun visor may short circuit, after a service repair is performed. If the vanity lamp wiring shorts, there is an increased risk of fire.

Fix: Chrysler will notify owners, and dealers will inspect and repair any damaged wiring, and install a new sun visor that properly routes the wire, free of charge.

When the adaptive cruise control is engaged and the driver presses the accelerator pedal to increase the vehicle's speed more than the cruise control system would on its own, the vehicle may continue to accelerate briefly after the accelerator pedal is released. The unintended continued acceleration may increase the risk of a crash.

Fix: Chrysler will notify owners, and dealers will re-flash the Driver Assistance System Module (DASM), free of charge.

The subject vehicles have a brake booster with a center shell that may corrode and allow water to get inside. The water inside could freeze and limit the braking ability of the vehicle, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will add a water diverter shield to the booster after the booster has been tested to confirm it can hold an acceptable amount of vacuum pressure. If the booster inspection confirms an unacceptable loss of vacuum pressure, the booster will be replaced.

Due to a disruption of computer communications and loose alternator ground wires, the affected vehicles may experience random illumination of multiple instrument cluster warning lights, loss of cluster illumination and loss of anti-lock brake system (ABS) and electronic stability control (ESC) function. Because of these conditions, the vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 101, "Controls and Displays," and No. 126, "Electronic Stability Control Systems." A loss of ABS and ESC function reduces the driver's ability to control the vehicle. Drivers would not be warned of brake system failures or any other failures which would be illuminated on the dashboard display. Either condition increases the risk of a crash.

Fix: Chrysler will notify owners, and dealers will update the ABS and instrument cluster module software and tighten the alternator ground wire, free of charge. Chrysler's recall campaign number is N58.

In the affected vehicles, when switching between daytime running lights and parking lights, electrical spikes may cause the parking lamps to turn off. Without properly functioning parking lamps these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, reflective devices, and associated equipment." Without parking lamps, the vehicle may not be as visible to other vehicles, increasing the risk of a crash.

Fix: Chrysler will notify owners, and dealers will update the Central Body Controller software, free of charge. Chrysler's recall campaign number is N42.
