Thin-gauge pressed steel and minimal factory underbody seam sealant leave the front subframe, rear axle mounting perches, and inner door sills vulnerable to accelerated corrosion from UK winter road salt. Moisture penetrates unsealed chassis joints, progressively weakening load-bearing suspension anchor points. If neglected, corrosion leads to dangerous structural failure where suspension components detach from the chassis, resulting in immediate MOT test failure. Rectifying advanced corrosion requires skilled metal fabrication and structural welding repairs.

The compact single-piston front brake calipers and rear drum wheel cylinders suffer from corroded slide pins and sticking hydraulic pistons, exacerbated by road grime and infrequent fluid renewals on low-mileage city runabouts. As the caliper pistons seize in their bores, the front brake pads drag continuously or fail to exert equal clamping force, causing dangerous vehicle pulling during braking, overheated friction surfaces, reduced brake efficiency, and MOT roller brake tester failures.

On 0.8-litre three-cylinder models, the optical ignition distributor contains an internal optical sensor and high-tension rotor that degrade under engine compartment heat cycling. Moisture ingress and carbon tracking within the distributor cap lead to misfiring under acceleration. When the car is parked warm for fifteen to thirty minutes, thermal heat soak prevents the internal optical sensor and coil from generating spark voltage, causing protracted cranking and refusal to restart until the engine bay cools down.
