PureTech 1.2 Wet Belt: Stellantis Coverage and the Years to Avoid

The PureTech 1.0 and 1.2 (internally the EB family) powered Peugeots, Citroëns, DS models and Vauxhalls from 2012, when Stellantis says the engine launched. None of them was sold new in the US, and the engine used a timing belt running in oil: the PureTech 1.2 wet belt.

Stellantis names two faults on the engine, in its own words: excessive oil consumption, and premature degradation of the belt itself.

What makes this case unusual is the response, not the fault: a ten-year warranty and a route to reimburse European owners who had already paid.

Which engines and which years

Stellantis's claim terms cover naturally aspirated 1.0 and 1.2 engines built from June 2012 to June 2022, and 1.2 turbo engines built from April 2014 to December 2025. PSA is the French group behind Peugeot and Citroën that became part of Stellantis.

So a 2023 to 2025 car with the turbo engine can still have the wet belt. The timing chain came with later engines, and the model year won't tell you which you have.

As always with these engines, the model year is a guide and not a guarantee. The engine code is what settles it, and telling a wet belt from a chain shows where to read yours.

What the PureTech 1.2 wet belt coverage says

From Stellantis's announcement, published May 7, 2025:

The conditions are the whole story

Two conditions decide whether the coverage is worth anything to you: the car has to have been serviced to the plan, and the repair has to go through the authorized network.

Stellantis's terms require that the servicing related to the fault complied with the manufacturer's maintenance plan.

In most markets the current terms let any automotive professional do the routine servicing; in the UK they require a Stellantis authorised repairer. The diagnosis and repair must go through the dealer network everywhere, and the three latest detailed invoices, or a network-stamped service book, are required.

Read practically, the Stellantis wet belt warranty comes down to three things:

• Your service history is the claim. Gaps in it are gaps in your coverage.
• Independent servicing counts in most markets, but not in the UK, provided it was to plan: correct intervals and correct specification, within 3 months or 3,000 km of each due date (1,800 miles in the UK).
• Don't have the repair done independently and then ask to be reimbursed. The diagnosis and the work need to go through the network to qualify.

The warranty extension isn't a recall, but there was a separate safety recall: 1.2 PureTech 110 and 130 hp engines built from March 2013 to April 2017, Peugeot code JZR and Citroën and DS code HFC. A parts maker's technical note says belt debris could block the brake vacuum pump.

What to look for if you already own one

The work here is paperwork rather than mechanics, and it belongs before something goes wrong rather than after. A claim is judged on what you can show, and what you can show is decided months earlier.

If you own a PureTech 1.2 with a wet belt, do these five things, and the first is the one with a clock on it:

1. Check your dates against the ten-year clock. It runs from the warranty start, usually first registration, so a car registered in 2016 is at or past it and a 2019 car has until 2029. Our free timing belt calculator checks the belt's own limits.
2. Gather the service history. Every invoice, every date, every mileage.
3. Check the oil monthly. A rising level and a gasoline smell means fuel dilution, which thins the oil the belt runs in, and the oil a wet belt needs is its own subject.
4. Watch oil consumption. It's one of the two named faults, so record it rather than just topping off.
5. Use the claims platform rather than assuming a dealer will volunteer it.

Is a used PureTech still worth buying?

With eyes open, yes.

The reasoning is the same as for the Ford: the design has a known weakness, the manufacturer has acknowledged it, and there's a documented route to help. A car with full history sitting inside the coverage window is a genuinely different proposition from an identical car with three years missing from its book.

What the coverage exists to pay for is a chain rather than a snap: the belt sheds material, the debris blinds the oil pump pick-up, and the engine runs short of oil. We set that out step by step in how wet belt engines fail.

Two practical rules. First, check the engine code if you want the chain, because turbo engines with the belt were built into 2025.

Second, if you're buying an earlier one, treat the service history as the main object being sold, because under these terms, it partly is. The wider buying checklist is in what to check before buying one.

Common questions

Asked most often

Is the PureTech 1.2 engine reliable?

It's economical, but Stellantis names two faults on the earlier belt-in-oil versions: excessive oil consumption and premature degradation of the belt. Later chain-driven versions don't carry the belt question.

Which PureTech engines have the wet belt?

Stellantis's terms cover naturally aspirated 1.0 and 1.2 engines built from June 2012 to June 2022, and 1.2 turbo engines built from April 2014 to December 2025. The engine code tells you which you have.

Does Stellantis pay for wet belt repairs?

Coverage was extended in March 2024 to 100% of parts and labor for up to 10 years or 112,000 miles, and a compensation platform later opened for expenses incurred between January 1, 2022 and December 31, 2024. The compensation depends on the car having been serviced to the manufacturer's plan.

Which model year is safe to buy?

The year alone won't tell you, because turbo engines with the belt were built into 2025. Check the engine code, then let the service history matter more than the year.
