Dodge Charger SRT Hellcat
6.2L supercharged V8, IHI twin-screw — 2.4L on standard Hellcat (11.6 PSI, 707-717 hp), 2.7L on Redeye (14.5 PSI, 797 hp, Demon-derived, forged rods + pistons). Black key fob = 500 hp via drive-by-wire throttle mapping. Red fob = everything. SRT Power Chiller diverts A/C refrigerant to cool intake. 2015-2016: snout bolt backs out, destroys bearings — $10-12k. Intercooler bricks leak coolant into cylinders. Heat soak costs 30-50 hp after repeated pulls — physics, not a defect.
Charger Hellcat — 717 hp sedan that broke every assumption
717 hp in a four-door sedan. 0-60 in 3.6 seconds with four doors and a trunk. The most powerful production sedan made in America. Same supercharger issues. The car that proves American excess has no logical endpoint.
Engine Weaknesses 3
Internal coolant passages in intercooler brick leak into intake. Coolant enters cylinders, causes cold-start misfires, scores cylinder walls. FCA replaces entire supercharger assembly under warranty (~$11,000).
Symptoms: Misfire on cold start, coolant level drops with no visible leak, white exhaust smoke
Early IHI superchargers had bolt backing out, destroying rotor bearings. Supercharger replacement $10-12k. 2017+ improved. Whine at idle is early warning.
Symptoms: Abnormal whining at idle, boost loss, metal debris in supercharger oil
Intake temps above 170F trigger timing retard. After repeated full-throttle passes, 30-50 hp loss until system cools. Physics, not a defect. Interchiller mods help for track use.
Symptoms: Power drop after multiple full-throttle runs, slow recovery between pulls
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.
