Dodge Charger Scat Pack
392 cubic inches, 4.09-inch bore, 485 hp — the biggest factory NA V8 of the 2020s. Forged steel crankshaft where the 5.7 uses cast iron — the real upgrade. Powder metal rods, cracked-cap design. Pistons are hypereutectic, not forged — ring lands too thin for boost, supercharger kits crack them. Same MDS lifter failure on automatics — engine replacement $15,000. Manual 392s skip MDS. VVT and active intake give 45 lb-ft more than the old 6.1 SRT. On 0W-40 at 5k intervals, the rotating assembly outlasts the car.
Charger Scat Pack — the only family sedan with 485 hp and burnout mode
485 hp, four doors, rear-wheel drive, launch control. The car that exists because someone at Dodge asked: what if we put the 392 in a sedan and sell it for $45k? School drop-off becomes an event. MDS lifter issue on every 6.4 — oil discipline is non-negotiable.
Engine Weaknesses 4
Same MDS failure as the 5.7 but with higher stakes. Deactivated rollers destroy camshaft, metal contaminates oil. Engine replacement $4,800-15,000 — replacements can fail the same way. Class action: Petro v. FCA. Manual 392s have NO MDS.
Symptoms: Progressive ticking to knocking, misfires, check engine light, metal in oil
Stock cast pistons not designed for boost. Ring land too close to crown, ring gap too wide. Supercharger or turbo kits crack pistons. Forged internals required before adding boost. Only affects modified engines.
Symptoms: Misfires under boost, loss of compression, knocking, catastrophic failure
Cast-iron manifold on aluminum head — thermal expansion mismatch breaks studs. Grade 8 replacement studs (6509863AA) are the fix.
Symptoms: Ticking on cold start from exhaust leak, disappears as metal expands
Same tick as the 5.7 from MDS valvetrain. Tick persisting past warmup signals lifter damage. 0W-40 synthetic at 5,000 mile intervals is the best prevention.
Symptoms: Ticking on cold start, may persist or disappear after warmup
Vehicle Weaknesses 8
Same TIPM defect as Challenger. Cascading failures: no-start, random horn, fuel pump relay failure. Recall covers certain VINs.
Same EPS circuit board contamination as Challenger. Loss of assist makes steering dangerously heavy. NHTSA recall for affected VINs.
Same alternator diode failure as Challenger. NHTSA recall 14V634000 covers 442,000 vehicles. Free dealer replacement.
Same LX platform as Challenger — bushings distort under 4,200+ lbs. Non-adjustable factory rear camber means bushing wear directly causes alignment drift and tire wear.
Door panels warp and detach where panels meet windows. Adhesive failure from sun/heat. Class action filed. Can interfere with side airbag deployment. 2015+ most affected.
Same UConnect freezing as Challenger. Hold volume + browse simultaneously to force reboot. Many units need hardware replacement.
4,200+ lb sedan with Hemi power generates extreme brake heat. Slotted rotors improve dissipation.
Same diff whine as Challenger. Synthetic gear oil change reduces noise significantly.
