All 3 Known Issues
The rear axle pinion nut can loosen due to undersized pinion spline that allows relative motion between the nut and companion flange. If the nut loosens, the rear axle can lock up without warning, causing loss of vehicle control. Official recall issued for pinion nut retainer installation.
Common Symptoms
- Humming noise from rear differential
- Clunking sound when accelerating or decelerating
- Vibration at highway speeds
- In worst case, sudden rear axle lockup
How to Fix
Contact Chrysler dealer immediately for recall completion - free installation of pinion nut retainer. Have differential fluid checked and changed. Inspect pinion seal for leaks. TSB 18-006-10 REV. B addresses driveline clunking.

Same HEMI 5.7L lifter/camshaft failure issue affecting all MDS-equipped engines. The MDS lifters have undersized needle bearings that fail from oil starvation at idle, causing catastrophic camshaft wear. Persistent ticking that worsens over time indicates lifter failure in progress.
Common Symptoms
- Persistent ticking noise at idle
- Ticking worsens over time
- Check engine light with misfire codes
- Metal shavings in oil
How to Fix
Replace all lifters, camshaft, and rocker arms. Consider Hellcat non-MDS lifter upgrade (8784AD) for MDS delete. Use Melling high-volume oil pump M10452HV (2009+). Maintain strict 3,000-5,000 mile oil change intervals with synthetic oil.

The Aspen shares the TIPM electrical module design with other Chrysler products. Fuel pump relay failure, random electrical activation, and battery drain are common. Same fundamental TIPM design flaw as Town & Country and 300.
Common Symptoms
- Vehicle won't start
- Fuel pump runs continuously with key off
- Random electrical malfunctions
- Battery drain overnight
