The 1989 Peugeot 405 has 4 recalls, the most serious being two separate fuel system fire risks: a fuel line that can deteriorate and leak after contact with a high-voltage wire in the engine compartment, and a fuel system that allows excessive fuel leakage in a rear-end collision.
The fuel line issue affects sedans and station wagons, where the supply line runs close enough to a high-voltage wire that prolonged contact breaks down the line material over time, eventually allowing raw fuel to escape near hot engine components and ignite. The collision-related fuel leak means that in a rear barrier impact, fuel escapes at levels beyond what safety standards permit, raising the risk of a post-crash fire.
On the visibility side, the plastic headlight lenses can cloud and yellow over time, gradually dimming the light output and reducing how far ahead the road is illuminated at night. There is also a brake lighting concern: the wiring configuration does not allow the brake lamp circuit to be tested when the ignition is turned partway between the "on" and "start" positions, meaning a burned-out brake light can go undetected, leaving following drivers without warning when the vehicle slows.
