For the valve operating system of the engine, if there are foreign materials in the raw material of the valve springs, the valve springs may lose some strength and eventually break. If this occurs, the engine will malfunction with abnormal noise, and in the worst case, it could stop running while the vehicle is in motion.

The bends on the fuel pipes may create too much stress on the welded sections. This excessive stress, together with corrosive components in the fuel, may cause microscopic cracks in the fuel line. If this problem is left unattended, a small fluctuation of fuel pressure may cause the cracks to grow, which in the worst case could lead to a fuel leak.

The fuel pipe is bent around the welded section, and therefore, the stress of that section may become too high and cause minute cracks in conjunction with corrosion causing materials in the fuel. If this problem is left unattended, fuel pressure fluctuation may cause the cracks to grow, which could, in the worst case, result in a fuel leak.

The diaphragm in the pulsation damper of the fuel system is made of improper material, and therefore, it may wear over a long period of time due to fuel pressure fluctuation. If this problem is left unattended, the diaphragm may crack, which could, in the worst case, result in a fuel leak.

The O-rings for the fuel pipes and the fuel injection nozzles have an inappropriate shape, and there may be excessive stress on them, caused by deformation created at the time of installation of the delivery pipes. If this problem is left unattended, the O-rings may crack, which could allow fuel to leak.

The edge of the rubber seal at the rear end of the brake master cylinder is improper, and therefore a part of the seal may be curled, caused by a braking operation after filling of brake fluid at factory, in which case the seal may allow brake fluid to leak. If the vehicle continues to be driven with this problem, the brake warning light may illuminate, and in the worst case, air could get into the brake fluid, which could result in reduced braking efficiency.

The bolt securing the rear wheel disc brake caliper may become loose if the vehicle is driven in such a manner as with frequent hard braking, because the processing of the bolt head bearing surface is inadequate. The loose bolt can cause abnormal noise during braking, and in the worst case, it comes off and the caliper comes to contact with the inside of the rear wheel damaging itself.

On certain vehicles, during the installation of the fuel pressure sensor on the delivery pipe on the engine, the sensor was not properly tightened. If left unfixed, the sensor may become loose due to engine vibration etc., causing the fuel to leak from its attachment part.

The torque of the check valve on the fuel pump is affected by the stress caused by the installation of the fuel pipe. For this reason, the check valve may become loose due to vibration of the fuel pump etc., even if it was tightened just to the correct torque during installation. If the valve becomes loose, fuel could leak from the attachment part.

On certain diesel vehicles with electronic control fuel injection pump, the coil wiring of the solenoid valve is improperly routed or welded. If left unfixed, the coil wiring may come off, causing the engine to stall.
