5.7L HEMI Lifter Tick and MDS Issues
The 5.7L HEMI V8 in the 300S and 300C develops the characteristic 'HEMI tick' from worn hydraulic roller lifters associated with the Multi-Displacement System (MDS). The ticking is most prominent on cold starts but can become constant. If ignored, worn lifters can damage camshaft lobes and cause misfires, rough idle, and reduced power.
Replace the affected lifters and camshaft with updated parts featuring improved needle bearings (latest 'AD' suffix revision). TSB 09-002-22 covers HEMI lifter noise diagnostics. Maintain oil changes every 5,000 miles with OEM-specified 0W-20 full synthetic. MDS delete kits are available as a preventive measure.
Est. Cost: $2,000 - $5,000ZF 8-Speed Transmission D-Clutch Failure
The ZF 8HP 8-speed automatic transmission develops D-Clutch pack failures causing the Malfunction Indicator Lamp to illuminate with DTC P0733-00 (Gear 3 Incorrect Ratio). Symptoms include slipping during 2-3 upshift, harsh shifts, and the transmission going into limp mode. The issue is caused by worn clutch pack friction material.
Perform a D-Clutch repair per TSB 21-022-22 (D-Clutch Repair). The repair involves replacing the clutch pack within the transmission. Reflash the TCM with updated software. A full transmission fluid exchange with ZF Lifeguard 8 ATF is performed during the repair.
Est. Cost: $800 - $2,500TPMS Sensor Battery Premature Failure
The Tire Pressure Monitoring System sensor batteries fail prematurely, rendering the TPMS inoperative and illuminating a persistent warning light. Without functioning sensors, the driver receives no alerts about tire pressure loss, which is a federal safety compliance issue.
NHTSA Recall 22V-578 covers inspection and replacement of TPMS sensors with updated units featuring improved battery life. All four wheel sensors and the spare should be checked and replaced at no cost.
Est. Cost: Covered under recallElectrical System and Air Bag Concerns
Owners report various electrical failures including faulty gauges, malfunctioning power windows, dashboard warning lights appearing without cause, and door locks operating erratically. More seriously, at least one complaint to NHTSA documented air bags failing to deploy during a 40 MPH frontal collision, raising critical safety concerns.
Perform a full electrical system diagnostic scan. TSB 08-050-22 covers body electrical diagnostics. Inspect all ground connections and clean corroded terminals. For air bag non-deployment concerns, have the SRS (Supplemental Restraint System) module inspected and ensure all recalls are completed. Report non-deployment events to NHTSA.
Est. Cost: $100 - $1,000HVAC Musty Odor and Climate Control Issues
A musty or mildew smell emanates from the HVAC vents, particularly when first turning on the air conditioning. The evaporator core accumulates moisture and bacteria, producing the unpleasant odor. Some owners also report the climate control not maintaining set temperatures and the gear shift occasionally getting stuck.
Treat the evaporator core with an antimicrobial foaming cleaner through the cabin air filter access. Replace the cabin air filter. TSB 24-008-22 addresses HVAC odor concerns. Running the fan on high with AC off for 2-3 minutes before shutting off the vehicle helps dry the evaporator and prevent mold growth.
