What happens if you skip it
- Neglecting transmission fluid service on the 8HP can lead to harsh shifting, delayed engagement, and eventual valve body failure requiring $3,000+ replacement.
- Deferred brake fluid changes allow moisture contamination that corrodes ABS module internals, a $1,200-$1,800 repair common on 2015-2021 LD Chargers.
- Ignoring spark plug replacement on HEMI V8s causes misfires that damage catalytic converters (up to $2,500 per side) and trigger MDS cylinder-deactivation faults.
- Skipping differential fluid service on limited-slip rear ends leads to clutch pack degradation, resulting in clunking during turns and costly differential rebuild.
- Overdue oil changes on supercharged Hellcat engines accelerate bearing wear and can cause catastrophic failure of the IHI supercharger's internal lubrication system.
Common issues at higher mileage
- 60,000+ mi
- ZF 8HP transmission may develop shudder or flare on 2-3 upshifts; often resolved with fluid service and software update, but some cases require torque converter replacement.
- 70,000+ mi
- Pentastar V6 engines can exhibit rocker arm tick or lifter noise due to oil passage debris; maintaining proper 0W-20 synthetic oil and performing an engine flush may help mitigate the issue.
- 80,000+ mi
- Rear suspension bushings and sway bar links wear on all trims, causing clunking over bumps; performance models with stiffer suspension see accelerated wear.
- 90,000+ mi
- Water pump weep holes may show coolant seepage on HEMI V8s, particularly 5.7L and 6.4L variants; replacement before catastrophic failure prevents overheating damage.
- 100,000+ mi
- Alternator bearing noise or voltage regulation issues emerge, especially on Hellcat models where electrical loads from fuel pumps and supercharger strain the high-output unit.
- 120,000+ mi
- Front lower control arm bushings and ball joints require replacement on all drivetrains, with AWD models showing earlier wear due to additional front-axle loading.
Common questions about the 2021 Dodge Charger
How often does a 2021 Dodge Charger need an oil change?
GarageHub estimates the 2021 Dodge Charger oil change interval at every 10,000 mi or 12 months, whichever comes first (estimated cost $60-$120); this is not the manufacturer's figure, so check your owner's manual.
What maintenance does a 2021 Dodge Charger need?
GarageHub's estimate of the services not to skip on a 2021 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.
