Top issues to watch for
The most serious TVR Chimaera problems ranked by severity. We track 8 known issues — here are the ones you need to know about first.
Dangerous
Outrigger Corrosion
The steel outriggers are structural members that support the fibreglass body and carry suspension pickup points. These tubular steel sections are prone to internal corrosion that weakens the structure before becoming externally visible. Corrosion typically starts from moisture ingress through drainage holes or mounting points and progresses inward. Structural failure of an outrigger can compromise crash protection and suspension geometry, making the car dangerous to drive. This is the most critical safety issue on the Chimaera chassis.
What happens if ignoredSevere outrigger corrosion can lead to structural collapse during normal driving or in an accident. The car becomes unsafe and unroadworthy. Repair requires cutting out corroded sections and welding in new steel, typically costing £1,000-£2,000 depending on the extent of corrosion. Some cars are written off due to the cost of proper structural repair.

Rover V8 Timing Chain Stretch
The Rover V8 engine uses a duplex timing chain that stretches with age and mileage, particularly when oil change intervals are extended. As the chain stretches, timing retards and the tensioner reaches its maximum travel. The oil pump is also chain-driven and can suffer reduced pressure as its drive chain stretches. This is a well-documented weakness of Rover V8 engines across all applications. If the timing chain jumps or breaks, valve-to-piston contact can occur, requiring expensive engine rebuild.
What happens if ignoredComplete timing chain failure results in valve damage and requires engine rebuild costing £3,000-£5,000. Even moderate chain stretch causes poor performance, increased fuel consumption, and accelerated wear of timing components. The car remains driveable but should be repaired promptly to prevent catastrophic failure.

Major
Power Steering Rack Failure
The power steering rack on the Chimaera is prone to internal seal failure leading to power steering fluid leaks and eventual loss of assistance. The rack gaiter deteriorates allowing dirt ingress which accelerates internal wear. MOT data shows this model fails at 14.4x the fleet average for power steering malfunctions and 55.9x for damaged steering gaiters. The combination of fluid leaks and gaiter deterioration creates a cascade failure where dirt contamination destroys the remaining seals.
What happens if ignoredComplete power steering failure makes the car very difficult to manoeuvre at low speeds and dangerous to drive. Steering rack replacement or refurbishment typically costs £800-£1,500. The car should not be driven if power steering has completely failed.

Suspension Component Corrosion
The TVR Chimaera's suspension uses steel components that are exposed to road salt and moisture without comprehensive protection. MOT data shows this model fails at 9.2x the fleet average for corroded suspension components. Lower wishbones, anti-roll bar links, and mounting points are particularly susceptible to corrosion that weakens the components before becoming externally obvious. The problem affects handling and safety as corroded components can fail suddenly under load.
What happens if ignoredCorroded suspension components can fail suddenly, causing loss of control and potentially serious accident. Components showing significant corrosion must be replaced immediately. Individual wishbone replacement costs £200-£400 per side, while comprehensive suspension refurbishment can cost £1,000-£2,000.
