The 1KD-FTV 3.0-litre four-cylinder turbodiesel engine is prone to failure of the copper injector seat washers that seal the fuel injectors against the cylinder head. Hot combustion gases blow past the failed seals and cook the engine oil inside the cam cover into thick carbon sludge. The sludge circulates down to the oil pan and cakes the fine wire mesh of the oil strainer pickup, causing oil starvation, crankshaft bearing seizure, and cracked pistons. Revised coated washers were introduced by Toyota.

High-specification LC4 and LC5 models feature Toyota Electronically Modulated Suspension (TEMS) with pneumatic rear air springs. Over years of exposure to UK road grit and salt, the flexible rubber air bellows perish, crack along the bottom fold, and leak air. The onboard suspension air compressor runs continuously in an attempt to maintain vehicle ride height until the electric compressor motor overheats and burns out, dropping the rear chassis onto its bump stops.

The heavy boxed steel ladder chassis is prone to severe internal and external rust perforations, exacerbated by UK winter road salt and water accumulation from boat launching or off-road use. Mud and wet grit enter internal chassis drain holes and become trapped against the inner rails above the rear axle, around the rear trailing arm mounts, and behind the fuel tank shield, rusting through structural steel and resulting in MOT failure.
