The 2020 Trackhawk pairs a 707-hp supercharged Hellcat motor with the ZF 8HP95 transmission in a 5,400-lb SUV—massive performance meets massive stress. Heat management and drivetrain abuse are the primary failure modes, especially in vehicles driven hard or modified.
Transmission Oil Cooler Failure
Common · high severityTypical onset: 40,000-70,000 mi
Symptoms: Transmission overheat warnings on dash, Limp mode after spirited driving or towing, Fluid contamination (coolant in trans fluid or vice versa), Burnt transmission fluid smell
Fix: Replace transmission oil cooler and flush both systems. 4-6 hours labor. Often requires new transmission fluid and filter. If contamination occurred, full transmission service or rebuild may be necessary.
Estimated cost: $1,200-2,800
Supercharger Heat-Soak and Intercooler Pump Failure
Occasional · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Power loss after consecutive hard pulls, Intercooler pump noise or failure to prime, Check engine light with intake air temp codes, Reduced boost pressure
Fix: Replace intercooler coolant pump (common failure point) and flush system. 3-4 hours labor. Some owners upgrade to aftermarket pumps and larger heat exchangers proactively.
Estimated cost: $800-1,500
Engine Bearing and Piston Ring Failure (High-Performance Use)
Rare · high severityTypical onset: 60,000-100,000 mi
Symptoms: Knocking or ticking from bottom end, especially cold start, Excessive oil consumption (more than 1 qt per 1,000 mi), Low oil pressure warnings, Metal shavings in oil filter, Blue smoke from exhaust on deceleration
Fix: Full engine rebuild or short block replacement required. 35-50 hours labor. This appears predominantly in modified vehicles, those with aggressive launch control use, or inadequate oil change intervals. Oil analysis critical for early detection.
Estimated cost: $15,000-25,000
Transmission Mount Failure
Common · low severityTypical onset: 50,000-80,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive drivetrain movement on hard acceleration, Vibration at idle in gear, Visible tearing or separation of rubber mount
Fix: Replace transmission mount. 1.5-2.5 hours labor. The torque from this powertrain destroys OEM mounts quickly. Many shops recommend polyurethane upgrades.
Estimated cost: $400-700
Fuel System Issues (High-Pressure Pump and Filter)
Occasional · medium severityTypical onset: 60,000-90,000 mi
Symptoms: Hard starting or extended crank time, Stumble or hesitation under heavy throttle, Fuel pressure codes (P0087), Surging at highway speeds
Fix: Replace high-pressure fuel pump or fuel filter assembly. Filter is often neglected—not a simple spin-on. 2-4 hours labor depending on component. Ethanol-heavy fuel accelerates wear.
Estimated cost: $800-1,800
Transfer Case and Driveline Binding
Occasional · medium severitySymptoms: Clunking or binding during tight turns on dry pavement, Jerking sensation in 4WD Auto mode, Transfer case overheating, Difficulty shifting into or out of 4WD modes
Fix: Service transfer case fluid (often neglected), inspect PTU (power transfer unit), and check for worn clutch packs. 2-3 hours labor for service; 8-12 hours if PTU or transfer case replacement needed.
Estimated cost: $400-3,500
Buy one only if you have a healthy maintenance budget and resist the urge to abuse launch control—when maintained properly they're thrilling, but deferred service or hard use gets expensive fast.
