The 1999 TVR Griffith with its Rover-derived 5.0L V8 is a hand-built British sports car where electrical gremlins, cooling system failures, and transmission issues dominate the problem list. Build quality varies wildly car-to-car due to low-volume production methods.
Chassis Rust and Structural Corrosion
Common · high severitySymptoms: Rust visible on tubular steel chassis, particularly rear suspension mounting points, Creaking or flexing over bumps, Failed MOT/inspection due to structural rust, Corrosion around outriggers and floor pan jacking points
Fix: Chassis-out restoration often required; serious repairs involve removing body (fiberglass separates from chassis), sandblasting affected tubes, welding in repair sections or replacement tubes, then reassembly. 40-60 hours labor minimum for proper repair, often much more.
Estimated cost: $8,000-15,000
Engine Overheating and Cooling System Inadequacy
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Temperature spikes in traffic or spirited driving, Coolant loss with no visible leaks, Oil cooler or engine oil cooler failures, Head gasket failure from repeated overheating, Warped heads requiring engine rebuild
Fix: System undersized from factory. Typical fix involves upgraded radiator, high-flow water pump, oil cooler replacement/upgrade, thermostat, and complete coolant flush. If heads are warped, you're looking at engine-out rebuild with head resurfacing. 8-12 hours for cooling upgrades; 50-80 hours for full engine rebuild.
Estimated cost: $1,500-3,000 for cooling system; $8,000-12,000 for engine rebuild
Borg-Warner T5 Transmission Failures
Common · medium severityTypical onset: 60,000-90,000 mi
Symptoms: Third gear synchro failure causing crunching on downshifts, Difficult shifting when hot, Oil leaks from transmission mounts and cooler lines, Complete transmission seizure in worst cases
Fix: T5 gearbox not really rated for the V8 torque. Rebuild involves removing transmission (tight quarters, 6-8 hours), synchro replacement, bearing refresh, new seals. Many upgrade to T5Z or Tremec TKO during rebuild. Transmission mounts wear rapidly and need replacing every 30k miles (2 hours).
Estimated cost: $2,500-4,500 for rebuild; $300-500 for mounts
Lucas Electrical System Failures
Common · medium severitySymptoms: Intermittent or complete headlight failures, Gauges reading erratically or not at all, Starting issues despite good battery, Alternator overcharging or undercharging, Corroded grounds causing random electrical gremlins
Fix: Hand-built wiring means every car is unique. Common issues: headlight assemblies corrode and fail (3 hours per side to replace), main ground points need cleaning and dielectric grease, alternator typically needs rebuild or replacement by 70k miles. Diagnosis is time-consuming due to poor wiring documentation. Plan 2-6 hours for electrical troubleshooting per issue.
Estimated cost: $500-2,000 depending on scope
Brake Caliper Seizing and Master Cylinder Failure
Occasional · high severityTypical onset: 50,000-80,000 mi
Symptoms: Uneven braking or pulling to one side, Brake pedal going to floor, Calipers sticking causing dragging and overheating, Brake fluid contamination from old rubber seals
Fix: AP Racing or Girling calipers require full rebuild with new seals, pistons, and hardware. All four calipers should be done simultaneously. Master cylinder typically fails around same time. Front calipers 4 hours, rears 3 hours, master cylinder 2 hours. Parts availability can be challenging.
Estimated cost: $1,800-3,000 for complete brake system overhaul
Fuel System Corrosion and Filter Clogging
Occasional · medium severityTypical onset: varies with storage conditions
Symptoms: Rough running or hesitation under load, Hard starting when hot, Fuel smell in cabin, Poor fuel economy
Fix: Steel fuel lines rust from inside out, especially if car sits. Fuel filter clogs from tank sediment (should be changed every 2 years, 1 hour job). Fuel pump failures common. In severe cases, tank removal and cleaning or replacement required (8-10 hours labor for tank work).
Estimated cost: $200-400 for filter/pump; $1,500-2,500 for tank replacement
Body-to-Chassis Bonding Failure
Occasional · medium severitySymptoms: Creaking and squeaking from body panels, Visible separation between fiberglass body and steel chassis, Door alignment issues that worsen over time, Stress cracks in gelcoat around mounting points
Fix: Fiberglass body is bonded to chassis with adhesive that degrades over time and with oil leaks. Proper repair requires body-off, cleaning both surfaces, re-bonding with proper adhesive (Sikaflex or equivalent). 30-40 hours labor for body removal, prep, and reinstallation.
Estimated cost: $4,000-7,000
Only buy if you're passionate about the driving experience and have deep pockets or DIY skills—ownership costs rival exotic cars despite the Rover engine, and finding someone competent to work on it is half the battle.
