The brackets for the clamps securing the fuel injector pipes do not have sufficient strength, and so they may break from engine vibration. In addition to this problem, the high-pressure pipes do not have a proper shape and their clamps do not have an appropriate structure, and therefore the clamp bolts may break or become loose from engine vibration, causing the clamps to fall off. If these problems are left unattended, the fuel injector pipes or the high-pressure pipes may crack, allowing fuel to leak, and in the worst case, the engine would stall and would not restart.

The frame end brackets (rear suspension supports) for the radius rods securing the rear axle have neither appropriate waterproofing structure nor proper rust proofing, and therefore they may rust when snow melting agent etc. is deposited inside. If this problem is left unattended, rust may progress and cause the brackets to crack, and in the worst case, the brackets could break and fall off with the radius rods, which could adversely affect the vehicle's stability.

For large-size all-wheel-drive vehicles, the wire harnesses along the left side frame may interfere with the brake hose bracket or the power steering pipe due to improper routing. If this problem is left unattended, the harnesses or the pipe may be damaged resulting from vehicle vibration, which in the worst case could cause the headlights not to illuminate, the engine to stall (and not to restart), or heavier steering.

The bracket securing the steering gearbox on the vehicle body does not have sufficient strength, and it may crack around the welded section from repeated dry steering. If this problem is left unattended, the bracket could break, in which case the steering gearbox would become unstable, and at worst, steering would become impossible.
