What happens if you skip it
- Neglecting transmission fluid changes on the ZF 8HP can lead to harsh shifting, torque converter shudder, and eventual valve body failure requiring $3,000+ replacement.
- Deferred brake fluid service on Brembo-equipped trims results in moisture absorption, boiling under hard braking, and spongy pedal feel that compromises stopping power.
- Ignoring rear differential fluid on RWD models—especially limited-slip units—causes clutch pack wear, whining noise, and costly differential rebuild or replacement.
- Skipping spark plug replacement on HEMI engines — particularly the supercharged 6.2L — leads to misfires, detonation under boost, and potential catalytic converter damage from unburned fuel.
- Failing to service AWD transfer case fluid results in binding, overheating, and catastrophic failure of the power transfer unit, often requiring complete replacement.
Common issues at higher mileage
- 60,000+ mi
- ZF 8HP transmission may develop torque converter shudder during light acceleration if fluid is not changed; TSB-issued software updates and fluid service typically resolve it.
- 80,000+ mi
- Pentastar V6 engines can experience rocker arm and lifter noise due to oil sludge buildup; consistent oil changes and using factory-spec 5W-20 synthetic mitigate this.
- 70,000+ mi
- HEMI V8 engines may develop exhaust manifold bolt failures causing ticking noise and exhaust leaks; aftermarket studs are a common permanent fix.
- 100,000+ mi
- Rear suspension bushings and control arms wear on all models, leading to clunking over bumps and alignment drift; inspect annually after 80k miles.
- 90,000+ mi
- Supercharged Hellcat engines may experience supercharger coupler wear, causing whine or slip under boost; coupler replacement is preventive maintenance for high-mileage forced-induction cars.
- 50,000+ mi
- Uconnect infotainment systems can develop touchscreen lag or freezing; software updates from the dealer often resolve persistent issues.
