- Intermediate Shaft (IMS) Bearing FailureSerious
The factory single-row and dual-row intermediate shaft (IMS) ball bearings fitted to the M96 flat-six engine can lose lubrication when their rubber oil seals degrade. Engine oil washes out the internal bearing grease, causing ball bearings to overheat, gall, and disintegrate. If the bearing collapses, camshaft timing goes out of sync, causing piston-to-valve contact and catastrophic internal engine failure requiring a complete rebuild or replacement unit.
- Front Radiator and Air Conditioning Condenser CorrosionModerate
The 986 Boxster routes cooling air through large bumper nostrils directly into front-mounted radiators and air conditioning condensers. Leaves, pine needles, road grit, and damp salt slurry collect in the narrow gap between the front AC condenser and rear coolant radiator. Because there are no factory protective grilles, trapped wet debris rots the aluminium cooling fins and tubes, causing refrigerant depressurisation and coolant loss with risk of engine overheating.
- Soft-Top Drain Channel Blockage and Cabin Water IngressModerate
Water draining from the convertible roof is channelled into plastic drip trays on either side of the rear deck and routed through rubber drain tubes down ahead of the rear wheels. In the wet UK climate, falling debris and foliage clog these narrow drain tubes. When water backs up, it overflows into the rear cabin and pools under the passenger seat foam, directly flooding the central immobiliser and alarm control module (CLU), immobilising the vehicle and causing widespread electrical failure.
