Top issues to watch for
The most serious Rover 45 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Subframe and suspension mounting point corrosion (R3)
The Rover 45 suffers from severe corrosion around suspension mounting points and subframe attachment areas. Poor rust protection from the factory combined with water traps in the body structure leads to structural weakness that can compromise vehicle safety. MOT data shows this model fails at up to 78.5 times the national average for load-bearing structure problems. The issue affects all engine variants and appears across all mileage ranges, indicating a fundamental design weakness rather than age-related deterioration.
What happens if ignoredStructural corrosion around suspension mounting points can lead to catastrophic failure where suspension components detach from the body. This creates an immediate danger to occupants and other road users. Repair typically requires extensive bodywork including welding or replacement of structural sections, often costing more than the vehicle's value.

Major
Suspension component corrosion (R3)
Suspension components on the Rover 45 suffer from excessive corrosion due to poor protective coating and water trap design. MOT data shows failure rates up to 412.7 times the national fleet average for suspension component damage or corrosion. This affects control arms, anti-roll bar links, and other suspension mounting hardware across all engine variants. The issue appears even on relatively low mileage examples, indicating inadequate factory corrosion protection.
What happens if ignoredFailed suspension components affect vehicle handling, braking performance, and safety. In severe cases, components can separate completely leading to loss of control. Replacement typically involves multiple components due to the extent of corrosion damage.

Major
General body corrosion (R3)
The Rover 45 has poor corrosion resistance due to inadequate rustproofing from the factory and design features that trap water and debris. Common areas include sills, wheel arches, door frames, and around the rear screen. This affects vehicle structural integrity and MOT compliance.
What happens if ignoredExtensive body corrosion leads to MOT failure and compromises structural integrity. Areas of concern include load-bearing structures which can affect safety. Repair costs can exceed the vehicle's value due to the extent of corrosion and the need for professional welding work.

Major
Brake binding and brake system corrosion (R3)
The Rover 45 experiences brake system problems including caliper seizure and brake hose corrosion. MOT data shows brake binding at 14.6 times the national average and brake hose ferrule corrosion at 19.1 times the average. Poor corrosion protection leads to seized brake calipers and corroded brake lines, affecting braking performance and safety.
What happens if ignoredBrake system problems create serious safety risks. Binding brakes cause overheating, reduced braking effectiveness, and premature component wear. Complete brake failure is possible if hoses fail or calipers seize completely. Immediate attention is required for any brake system defects.
