TRX Hellcat — 702 hp, 4.7 mpg city, zero regrets
Legendary!Engine Overview
The RAM 1500 TRX DT is available with one engine variant at 264 hp.
6.2-liter supercharged V8 with 702 hp in a pickup — 0–60 in 4.5 sec, quarter mile 12.9 sec. Supercharger intercooler coolant circuit leaks internally on early units — cold-start misfires from coolant in cylinder 3. FCA replaces entire supercharger under warranty (~$11,000 list price). Heat is the limiter: intake air temps above 150°F trigger timing retard. Not a daily-driver in disguise — fuel economy 15–20 mpg without restraint.
- !! Supercharger intercooler leaks — coolant in cylinder from 5,000 km
Internal coolant passages inside the supercharger charge air cooler leak into the engine. Coolant enters cylinder 3, cold-start misfires follow. FCA replaces the entire supercharger assembly under warranty (~$11,000 list). Primarily affects early production 2021–2022.
Symptoms: Misfire on cold start until operating temperature reached, coolant level drops with no external leak visible - !! Heat management — power reduction at high charge air temps
Once intake air temperatures exceed 150°F the ECU pulls ignition timing and boost pressure. During track use or repeated full-throttle pulls, noticeable power loss. Interchiller available as aftermarket solution for frequent performance use.
Symptoms: Power drop after multiple full-throttle runs, slow recovery between pulls - !! Supercharger snout bearing wear — grinding noise at idle from 50,000 km
IHI twin-screw supercharger front snout bearings wear from heat and high RPM. Stock bearings rated for 10,000-12,000 RPM, supercharger spins faster under full boost. Grinding or chirping noise at idle is the first sign. Dealer warranty: entire supercharger replaced ($10,000+ list). Aftermarket rebuild with ceramic bearings $800-$3,800 depending on scope. Jon Bond Performance and Kong Performance are the established rebuild shops.
Symptoms: Grinding or chirping noise from supercharger at idle, noise gets louder with mileage, mechanic stethoscope on snout tip confirms grinding vs. normal whoosh
Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Rear window leaks — water intrusion into cab Seal on the sliding rear window and CHMSL gasket at the rear roofline allows water entry. Primarily affects 2019–2021, often associated with the sliding glass window. TSB exists, sealant kit available under warranty. Symptoms: Wet carpet behind rear seat, damp headliner, mold smell from 30,000 km | Low | |
| Paint chipping and orange peel — thin clear coat Owners report 50-150+ paint chips within the first year, primarily on hood, bumper, and grille. Orange peel texture visible and tactile on darker colors (Graphite Gray, Patriot Blue, Black Diamond). 2022+ models significantly worse than 2019-2021 builds. Generally not covered under warranty — dealers classify as road damage. PPF (paint protection film) recommended on new purchases. Symptoms: Visible paint chips clustered on front bumper and hood, textured orange peel surface on body panels, paint peeling near front sensors on bumper fascia from 15,000 km | Medium | |
| Aluminum hood corrosion — paint bubbling from inside Aluminum hood develops oxidation corrosion beneath the paint layer, visible as bubbling on the surface. Not traditional rust — aluminum oxide forms from moisture trapped between paint and bare aluminum. Palpable from both sides of the hood. Similar issue documented on Ford aluminum-body vehicles. Warranty coverage under 5-year corrosion warranty if caught early, but RAM has denied claims on older vehicles. Symptoms: Paint bubbling on hood surface, bumps felt on underside of hood, no visible paint chips or cracks at onset from 80,000 km | Medium |
