2021 Dodge Challenger

Both the 5.7L and 6.4L HEMI engines can develop lifter failures causing a ticking or knocking noise from the valvetrain. The Multi-Displacement System (MDS) hydraulic lifters wear prematurely due to under-sized needle bearings, potentially leading to camshaft lobe damage. Metal debris from failed lifters can contaminate the oil system and cause additional engine damage.

Replace all MDS and non-MDS lifters, camshaft, and associated hardware. TSB 09-002-22 covers HEMI lifter noise diagnostics. Use updated 'AD' suffix lifters. Change oil every 5,000 miles with OEM-specified full synthetic. Consider MDS delete kit to eliminate the system entirely.

The ZF 8HP 8-speed automatic transmission exhibits harsh shifting, jerking during gear changes, and delayed engagement. Some owners report the vehicle refusing to shift gears or slipping into neutral unexpectedly. The torque converter may shudder at light throttle between 30-50 mph. These issues create safety concerns, particularly in traffic.

Reflash the TCM with updated calibration software. TSB 21-019-22 addresses shift quality. A transmission fluid flush with ZF-approved ATF may resolve torque converter shudder. Valve body replacement for persistent shift quality complaints.

The Tire Pressure Monitoring System sensor batteries fail prematurely, causing inoperative tire pressure monitoring and a persistent TPMS warning light on the dashboard. Without functioning TPMS, the driver has no real-time awareness of tire pressure changes, which is particularly concerning for a high-performance vehicle.

NHTSA Recall 22V-578 covers replacement of TPMS sensors with updated units at no cost. All four wheel sensors and the spare tire sensor should be checked and replaced if necessary.

Owners report extreme difficulty filling the fuel tank, with the fuel pump nozzle clicking off repeatedly as if the tank is full when it is not. Fueling can take 15-20 minutes for a full tank. The issue is caused by the EVAP system vent valve or fuel filler neck design creating back-pressure that triggers the pump nozzle shutoff.

Replace the EVAP canister vent valve and inspect the fuel filler neck for obstructions. TSB 14-005-22 covers fuel fill difficulty diagnostics. Inserting the nozzle only halfway and fueling at a slower rate is a temporary workaround. Updated fuel filler neck components are available.

Owners report sudden loss of power during acceleration, engine surges at steady throttle, and illuminated Check Engine lights with no clear resolution. The issue is intermittent and difficult to replicate at the dealer. It can be caused by faulty throttle body sensors, fuel injector issues, or PCM software bugs.

Update the PCM software to the latest calibration. TSB 14-008-22 addresses engine performance and driveability concerns. Clean the throttle body and inspect fuel injectors. Replace the throttle position sensor if erratic readings are found during diagnostic scan.

Chrysler (FCA US, LLC) is recalling certain 2021 Dodge Challenger vehicles. The affected vehicles do not illuminate their safety system status indicators sufficiently in both daylight and nighttime driving conditions. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 101, "Control and Displays."

Without visible safety system indicators, a driver may not receive information regarding vehicle safety, increasing the risk of injury or a crash.

Dealers will re-program instrument clusters with the correct software version, free of charge. Owner notification letters were mailed on October 5, 2021. Owners may contact FCA US LLC customer service at 1-800-853-140. FCA US LLC's number for this recall is Y58.

Chrysler (FCA US, LLC) is recalling certain 2020-2021 Dodge Challenger, Dodge Charger, and Chrysler 300 vehicles. During manufacturing, the windshield may not have been properly bonded to the vehicle, allowing it to detach in a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 212, "Windshield Mounting."

A windshield that separates from the vehicle during a crash can increase the risk of injury.

Dealers will remove and replace the front windshield urethane sealant, free of charge. Owner notification letters were mailed on August 31, 2021. Owners may contact FCA US LLC customer service at 1-800-853-1403. FCA US LLC's number for this recall is Y47.
