Dodge Durango 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.
710 hp, one model year, 3,000 built
Most powerful production SUV of its time. Limited to 2021. Sold out instantly. Becoming a collectible.
Engine Weaknesses 2
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
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 7
Totally Integrated Power Module fails without warning. No-start, fuel pump relay sticks, all warning lights. Primarily 2011-2013.
8-speed auto (845RE/ZF 8HP) develops shuddering during low-speed acceleration. Worn torque converter clutch is the primary cause.
Alternator may suddenly fail. Recall P60 covers 2011-2014 models.
Full-width LED taillight leaks water through degraded seals. Class action filed (Cranstoun v. FCA).
Upper rear shock mounts develop play — design flaw, not normal wear.
Touchscreen delaminates within 2-4 years. Substitute manufacturer in 2017-2018 used defective adhesive.
Front rotors warp prematurely due to heavy curb weight.
