The 2020 TVR Griffith is a low-volume British sports car powered by a Ford-sourced 5.0L Coyote V8 mated to a Tremec manual transmission. Production issues and extremely limited numbers mean field data is sparse, but early adopters report cooling system stress, transmission mounting failures, and electrical gremlins typical of hand-built exotics.
Transmission Mount Failure
Common · medium severityTypical onset: 5,000-15,000 mi
Symptoms: Clunking during hard shifts or throttle transitions, Excessive drivetrain movement visible from outside, Vibration at idle in gear
Fix: The rear transmission mount fatigues quickly due to the Coyote's torque and aggressive driving. Replacement requires lifting the transmission slightly; budget 2-3 hours labor. Upgraded polyurethane mounts are recommended over OEM rubber.
Estimated cost: $600-1,200
Transmission and Engine Oil Cooler Leaks
Occasional · high severityTypical onset: 10,000-30,000 mi
Symptoms: Oil spots under car after spirited driving, Temperature spikes during track use, Low fluid warnings, Burning oil smell
Fix: Both coolers use AN fittings and braided lines that can weep at connections or crack from vibration. Transmission cooler is particularly vulnerable. Diagnosis 1 hour, replacement 3-5 hours depending on which cooler and accessibility. Track cars see this earlier.
Estimated cost: $1,500-3,500
Fuse Box Corrosion and Electrical Faults
Occasional · medium severitySymptoms: Intermittent gauge failures, Headlight flickering or failure, No-start conditions with good battery, Random warning lights
Fix: Engine bay fuse box placement exposes it to heat and moisture. Corrosion on terminals causes cascading electrical issues. Diagnosis is time-consuming (2-4 hours); fuse box replacement is straightforward once identified (2 hours). Often requires individual circuit tracing.
Estimated cost: $800-2,000
LED Headlight Module Failure
Occasional · low severitySymptoms: One or both headlights dim or dead, Condensation inside housing, DRL malfunction
Fix: Custom LED modules are not well-sealed and fail from moisture ingress or driver circuit burnout. Modules are expensive and dealer-only; replacement is 1-2 hours per side. Some owners retrofit aftermarket LED assemblies as a permanent fix.
Estimated cost: $1,200-2,800
Brake Caliper Seizure
Rare · high severityTypical onset: 20,000-40,000 mi
Symptoms: Pulling to one side under braking, Excessive heat from one wheel, Premature pad wear on one side, Sticking or dragging sensation
Fix: Performance Brembo-style calipers can seize if not serviced regularly, especially on garage-kept cars with low annual mileage. Rebuild kits are available; front calipers take 3-4 hours per axle, rears 2-3 hours. Replacement calipers are extremely expensive.
Estimated cost: $1,000-2,500
Fuel Filter Clogging (Early Production)
Rare · medium severityTypical onset: 15,000-25,000 mi
Symptoms: Rough idle or stumbling under load, Hard starting when hot, Loss of power above 4,000 RPM
Fix: Early cars left the factory with debris in fuel systems. In-line filter clogs prematurely. Replacement is straightforward (1 hour) but requires fuel system depressurization. Follow with tank inspection if symptoms persist.
Estimated cost: $200-500
