- Skipping transmission fluid changes can lead to harsh shifting, delayed engagement, and transmission failure by 120,000+ miles, especially in the 8-speed automatic.
- Neglecting brake fluid flushes increases moisture absorption, causing brake fade, corrosion of brake lines, and potential brake system failure in emergency situations.
- Ignoring differential fluid changes accelerates gear wear, resulting in whining noises, loss of traction, and expensive differential replacement ($1,500โ$2,500).
- Delaying spark plug replacement beyond 100,000 miles causes misfires, reduced fuel economy, and catalytic converter damage on the Pentastar and HEMI engines.
- Skipping coolant flushes allows corrosion of the water pump, heater core, and engine block, leading to overheating and head gasket failure.
- Postponing tire rotations on 4WD models causes uneven wear and drivetrain binding, forcing premature replacement and potential transfer case damage.
Common issues at higher mileage
- 80,000+ mi
- Transmission hesitation and delayed shifts in the 8-speed automatic; often resolved by transmission fluid flush but may indicate internal wear.
- 100,000+ mi
- Water pump failure on Pentastar V6 engines; symptoms include coolant leaks and overheating; replacement costs $400โ$700.
- 120,000+ mi
- Rear differential noise (whining or grinding) due to worn gears; common on 4WD models with infrequent fluid changes.
- 100,000+ mi
- Brake caliper sticking and uneven pad wear; more prevalent in vehicles driven in wet/salty conditions without regular brake service.
