Peugeot 508 Problems And Reliability

Diesel engine

On the 2.0 BlueHDi 160 and 180 hp diesel engines the temperature warning light may be on, due to a fault in the water pump. On the side of the 1.5 BlueHDi 130, the power cord circuit, sometimes buggy, can lead to untimely setup.

A fuel leak was also identified, and a change to the timing belt, too loud, was made in the version before spring 2019.

Gasoline engine

The only gasoline engine available, available in 180 or 225 hp, the 1.6 PureTech may experience illumination from the diagnostic warning light on the instrument panel, to signal a fault in the engine harness or a problem with the fuel pump.


The message displayed on the instrument panel could indicate anomalies in the electronic management of the transmission, on a 508 equipped with an automatic gearbox. Only versions prior to fall 2019 may be affected.

Body work

Some 508s can indulge in blinking: daytime headlights sometimes show multiple malfunctions, independently of each other. The back light may also have water infiltration, or it may not work. They were later replaced as collateral.


Several cases of non-operating air conditioners were referred to in the 508 manufactured until February 2019, because of the compressor. On board furniture sometimes presents assembly defects, which do not bode well for aging.

Peugeot 508 “2”: more info

Since its appearance in October 2018, 508 have sold 24,027 units in France, and 63,752 units in Europe (end of February 2020). At the Mulhouse plant, production of the hybrid version doesn’t start until the end of 2019.

Peugeot 508: a major reminder

Particulate filters: (summer 2019) The first series of 508 BlueHDi produced, leaving the factory during the summer of 2018, may experience filter inefficiency. It is checked and replaced if necessary.

Peugeot 508: Conclusion

Somewhat well born and very comfortable to ride, the second generation 508 suffered from some reliability flaws, often of electrical or electronic origin. The failure mainly affected the first model produced, for which it can be blamed on young people.
