What happens if you skip it
- Neglecting transmission fluid changes can cause harsh shifting and premature failure of the ZF 8HP unit, a $4,000+ repair not covered under powertrain warranty after 60,000 miles.
- Deferred brake fluid service on Brembo-equipped models leads to moisture contamination, reducing boiling point and risking brake fade during aggressive driving or emergency stops.
- Ignoring differential fluid changes on limited-slip rear ends causes clutch pack degradation, resulting in clunking during turns and eventual complete differential failure.
- Skipping spark plug replacement on supercharged Hellcat engines can cause misfires under boost, potentially damaging catalytic converters ($1,200+ each) or causing detonation that cracks pistons.
- Overdue coolant service accelerates corrosion in the aluminum cylinder heads and cooling system components shared by all HEMI engines, leading to head gasket failure or water pump leaks.
Common issues at higher mileage
- 60,000+ mi
- ZF 8-speed transmission may develop shudder or delayed engagement if fluid not serviced; early fluid change often resolves symptoms.
- 80,000+ mi
- Water pump failure on 3.6L Pentastar V6 engines, often preceded by coolant seepage or bearing noise from the front of the engine.
- 70,000+ mi
- Rear suspension bushings and sway bar links wear prematurely on all models, causing clunking over bumps and imprecise handling.
- 100,000+ mi
- HEMI 'tick' from exhaust manifold bolt failure or lifter wear becomes more pronounced; may require manifold replacement or lifter service.
- 90,000+ mi
- Alternator failure more common on high-output HEMI models due to increased electrical demands from performance accessories and cooling fans.
- 120,000+ mi
- Front lower control arm bushings and ball joints show significant wear, particularly on AWD models and those driven in cold climates.
Common questions about the 2018 Dodge Charger
How often does a 2018 Dodge Charger need an oil change?
GarageHub estimates the 2018 Dodge Charger oil change interval at every 10,000 mi or 12 months, whichever comes first (estimated cost $45-$90); this is not the manufacturer's figure, so check your owner's manual.
What maintenance does a 2018 Dodge Charger need?
GarageHub's estimate of the services not to skip on a 2018 Dodge Charger: engine oil & filter every 10,000 mi / 12 mo; tire rotation every 7,500 mi; brake fluid flush every 24 mo; brake pad inspection & replacement every 40,000 mi. These intervals are estimates, not the manufacturer's maintenance schedule. Check your owner's manual for the exact figures.
What goes wrong on a Dodge Charger at higher mileage?
What owners report as the miles add up — 60,000+ mi: ZF 8-speed transmission may develop shudder or delayed engagement if fluid not serviced; early fluid change often resolves symptoms. 80,000+ mi: Water pump failure on 3.6L Pentastar V6 engines, often preceded by coolant seepage or bearing noise from the front of the engine. 70,000+ mi: Rear suspension bushings and sway bar links wear prematurely on all models, causing clunking over bumps and imprecise handling. 100,000+ mi: HEMI 'tick' from exhaust manifold bolt failure or lifter wear becomes more pronounced; may require manifold replacement or lifter service. 90,000+ mi: Alternator failure more common on high-output HEMI models due to increased electrical demands from performance accessories and cooling fans. 120,000+ mi: Front lower control arm bushings and ball joints show significant wear, particularly on AWD models and those driven in cold climates.
