eTorque System Stalling and 48V Battery Failure
The 5.7L and 3.6L eTorque mild hybrid system causes unexpected engine stalls while driving, often triggering automatic parking brake engagement. The 48V lithium-ion battery pack fails prematurely, leading to no-start conditions and ESS (Engine Stop-Start) malfunction. NHTSA opened Preliminary Evaluation PE24018 covering approximately 150,000 vehicles. Cold weather significantly worsens battery performance.
Replace the 48V battery pack assembly. Update the eTorque system and PCM software. TSB 14-010-22 addresses MGU communication faults. Replace the Motor Generator Unit if a whining noise is present. Note: the truck has no traditional alternator; the eTorque MGU charges both the 48V and 12V systems.
Est. Cost: $500 - $3,500Exhaust Manifold Bolt Breakage
The 5.7L HEMI exhaust manifold bolts fracture due to repeated thermal expansion and contraction cycles, causing an exhaust leak. Symptoms include a ticking noise on cold start that may quiet as the engine warms, reduced fuel economy, and an exhaust smell in the cabin. The broken bolts can damage the manifold and cylinder head threads.
Replace the broken exhaust manifold bolts with updated Mopar bolts (improved metallurgy). If the manifold is warped or cracked, replace the manifold assembly. TSB 09-011-22 covers cold-engine ticking noise from the exhaust manifold area. Typically covered under powertrain warranty.
Est. Cost: $400 - $1,500Uconnect 12-Inch Touchscreen Unresponsive
The 12-inch Uconnect 5 touchscreen freezes, goes completely black, or becomes unresponsive to all inputs including hard buttons. The backup camera may still function even when the screen is black. Owners report needing to shut off the truck and wait several minutes before the system recovers. Radio presets and settings are occasionally lost.
Perform a Uconnect software update. TSB 08-058-22 covers infotainment system diagnostics. Perform a system master reset if a software update does not resolve the issue. Replace the head unit if the screen shows hardware failure symptoms.
Est. Cost: $0 - $1,500Rearview Camera Wiring Harness Short
The rearview camera wiring harness may short circuit, preventing the backup camera image from displaying when the vehicle is in reverse. This is a federal safety standard violation (FMVSS 111 - Rear Visibility). The short can also affect trailer camera and surround-view functionality.
NHTSA Recall 22V-693 requires inspection and replacement of the rearview camera wiring harness. Dealers will repair or replace the affected harness at no cost. Check for any signs of melted insulation near the tailgate hinge area.
Est. Cost: Covered under recallElectronic Stability Control (ESC) Software Malfunction
A software bug in the Anti-lock Brake System (ABS) control module can disable the Electronic Stability Control system without warning. The ESC warning light may or may not illuminate when the system is inactive, leaving the driver unaware that a critical safety system is not functioning, especially dangerous when towing.
NHTSA Recall 22V-820 requires dealers to update the ABS control module software. The reprogramming is free of charge and takes approximately one hour. Verify that the ESC light operates correctly after the update.
