The 2018 Trackhawk is a 707-hp supercharged beast that's incredibly capable but pushes the ZF 8HP90 transmission and Hellcat-derived engine to their absolute limits. When used hard (as intended), expect significant drivetrain wear and heat management issues that don't appear on lesser Grand Cherokees.
Symptoms: Transmission temperature warning on dash during spirited driving or towing, Harsh shifting or limp mode after sustained high-load use, Transmission fluid discoloration or burnt smell during service, Oil cooler lines seeping at crimped connections
Fix: External oil cooler lines crack or the cooler itself clogs with clutch material. Requires dropping the transmission pan, sometimes full cooler replacement with upgraded lines. 4-6 hours labor depending on whether you're just doing lines or the full cooler assembly. Strongly recommend fluid flush with Mopar-spec ATF+4 after repair.
Estimated cost: $1,200-2,800
Supercharger Belt Slip & Pulley Bearing Wear
Occasional · high severity
Typical onset: 40,000-70,000 mi
Symptoms: Intermittent supercharger whine that changes pitch or volume, Loss of boost pressure under hard acceleration (feels slower than normal), Squealing from engine bay during cold starts, Belt dust or rubber particles around supercharger area
Fix: The 2.7L IHI supercharger uses a dedicated 10-rib belt that can slip when worn or if the idler pulley bearing fails. Belt replacement is 2-3 hours but if the pulley bearing is gone, you're looking at 5-7 hours for proper supercharger removal and pulley replacement. Do NOT ignore this—belt failure at high RPM can grenade the supercharger.
Estimated cost: $800-3,500
Engine Connecting Rod Bearing Failure (High-Mileage or Abused Units)
Rare · high severity
Typical onset: 60,000-90,000 mi
Symptoms: Deep knocking sound from lower engine, especially when cold or under load, Metal shavings in oil during changes, Sudden oil pressure drop, Catastrophic failure: thrown rod through block
Fix: The supercharged 6.2L Hemi runs high cylinder pressures and some units (especially those with extended oil change intervals or track use) develop rod bearing wear. Requires full engine-out teardown, crank polishing or replacement, new bearings, and reassembly. 25-35 hours labor. Many owners opt for short block replacement instead of rebuild. This is a $15K+ job at indie shops, more at dealers.
Estimated cost: $15,000-25,000
Transmission Mount Collapse
Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: Clunking when shifting from park to drive or reverse, Excessive driveline shudder during hard launches, Visible sagging of transmission tailshaft when inspected on lift, Increased cabin vibration at idle in gear
Fix: The 707 hp and 645 lb-ft overwhelm the factory rubber transmission mount, especially if you're doing launches. Mount replacement is straightforward but requires supporting the transmission. 2-3 hours labor. Aftermarket polyurethane mounts last longer but increase NVH.
Estimated cost: $400-800
Fuel System Contamination & High-Pressure Pump Issues
Occasional · medium severity
Symptoms: Hard starting or extended cranking, especially when hot, Rough idle or hesitation under light throttle, Check engine light with fuel pressure sensor codes (P0087, P0191), Loss of power at high RPM
Fix: The high-pressure fuel system is sensitive to contamination. Some owners see premature fuel filter clogging or high-pressure pump wear if they've run questionable fuel. Filter replacement is 1 hour, but if the pump has failed you're looking at 4-5 hours for pump R&R plus fuel system cleaning. Always run top-tier 91+ octane.
Estimated cost: $300-2,200
Active Exhaust Valve Motor Failure
Occasional · low severity
Typical onset: 40,000-100,000 mi
Symptoms: Check engine light with exhaust valve control codes, Stuck-open exhaust (always loud) or stuck-closed (always quiet), Rattling from exhaust tips during mode changes, No response when toggling exhaust modes on dash
Fix: The electric motors that control the exhaust valves can fail, especially in salt-belt states. Replacement involves cutting exhaust clamps and swapping valve assemblies. 2-3 hours per side. Not a safety issue but annoying if you like switching between stealth and aggressive modes.
Estimated cost: $800-1,400
Owner tips
Change transmission fluid every 30,000 miles if you drive hard—the ZF in this application runs hotter than in lesser Jeeps.
Use only 91+ octane top-tier fuel; the supercharged Hemi is extremely knock-sensitive and the ECU will pull timing aggressively on cheap gas.
Do oil analysis every other change (around 5,000 mi intervals) to catch bearing wear early—blackstone or equivalent can save you from a $20K engine job.
Inspect supercharger belt and idler pulley at every oil change; a $50 belt prevents a $5,000 supercharger replacement.
Budget for a transmission cooler upgrade if you track the vehicle or tow—the factory setup is marginal.
Buy one only if you have a $5K annual repair fund and aren't afraid of a transmission or engine rebuild—these are phenomenal performers but they break expensive parts when used as intended.
