Dodge Challenger maintenance: the schedule, the costs, the traps
A sports coupe (muscle car) with a gas powertrain. Below: the service intervals with real cost ranges, the repairs Challenger owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

Known repair windows
What Challenger owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.
5.7L HEMI lifter / camshaft failure (MDS 'HEMI tick')
high severity60,000-120,000 mi · $2,500-$5,000
Collapsed MDS lifter scores cam; ticking then misfire; delete-MDS cam common fix
Exhaust manifold bolts shear (HEMI)
medium severity60,000-130,000 mi · $300-$800
Cold-start tick/exhaust leak; broken studs at head

High-hp trims eat staggered performance tires and rotors
Operator notes
Final year 2023 for the LC/LA-platform gas Challenger. Timing CHAIN on all engines (Pentastar V6, 5.7/6.4 HEMI, 6.2 supercharged). 8-spd ZF auto or 6-spd Tremec manual. Requires 91+ octane on HEMI/SRT. Severe-service (spirited/track) roughly halves fluid intervals.
When the smart money sells
On fleet math, a gas Challenger retires around 95,000 miles - but the exit window opens earlier here: Supercharger snout bearing / IC pump (Hellcat 6.2) risk window ($1,500-$3,000) opens ~40,000 mi. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
