2023 Peugeot 508: known problems and what to check

Known faults on the 2023 Peugeot 508

Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

• Timing belt that runs in oil (PureTech petrol)

  1.0 and 1.2 PureTech petrol

  The 1.0 and 1.2 PureTech petrol engines use a timing belt that runs in the engine oil (a “wet belt”). It can break down early and shed rubber that blocks the oil supply, which can wreck the engine. Some also burn too much oil. Stellantis now covers earlier engines for belt and oil-burning problems for up to 10 years or 112,000 miles, as long as the car has been serviced on schedule.

  At the viewing: Ask for a full service history showing the right oil, and when the belt was last checked or changed. Check the oil level on the dipstick, and that no oil-pressure or engine warning light stays on.

Questions to ask the seller before buying a 2023 Peugeot 508

Ask before you travel to see it. A seller who knows the car will have answers, and receipts.

1. When was the timing belt last checked or changed, and has it had the right oil at every service? Is the car still within Stellantis’ extended PureTech cover?
2. Can I see the service history and receipts for any big jobs?

What to check on a 2023 car

• Warranty left

  Ask for the date it was first registered and check how much of the maker’s warranty is left, and that it transfers to you. Electric and hybrid batteries usually have a longer, separate warranty.

• Servicing

  Servicing on time with the maker’s schedule keeps the warranty valid. Ask for the service book or the dealer’s digital record.

• Finance

  Nearly new cars are often still on finance. A history check shows outstanding finance, and whether it has been written off or stolen.

• Recalls

  Ask whether any recall work has been done, and check the reg on GOV.UK’s free recall checker.

• Logbook (V5C)

  The name and address should match the seller, and the VIN on the V5C should match the car.
