Problematic

Reliability, common problems and owner reviews for the Opel Grandland 1.2 PureTech (EB2). Check this before you buy used.

The 1.2 PureTech turbo (EB2 — shared across the 208/2008/Corsa/Grandland) carries the engine family's notorious wet-timing-belt (belt-in-oil) reputation: on the belt cars it degrades and can shed material that blocks the oil pickup and destroys the engine. The good news is that this late, post-2021 308 III sits at the point where Stellantis was revising the design toward a chain and tightening the belt/oil regime, so a late car is less of a gamble than an early PureTech — but you must verify the specific car's timing setup and service history. With the correct (frequent) oil regime and the belt done on the tighter schedule it's lively and refined; treat the oil seriously and confirm the belt-vs-chain status.

Same engine, other cars

This is the same physical engine (5G06) sold under different names across brands. Reliability is broadly shared — cross-check these:

Known Issues

Wet timing belt failure (EB2)critical

Belt-in-oil degrades → debris blocks oil pickup → oil starvation → engine destruction. Notorious PureTech fault.

Fix / Workaround: Replace wet belt early (well ahead of schedule); strict oil; or buy a chain-era car.

Repair cost: €500–€4000

Typically appears after: 60,000 km

Oil dilution / tensionerrecurring

Oil dilution and tensioner wear compound the belt risk.

Fix / Workaround: Frequent oil changes; monitor level; check history.

Repair cost: €200–€1500

Typically appears after: 70,000 km

Wet timing belt / oil-pump debris (1.2)critical

1.2 PureTech wet belt degrades in oil; debris can block the oil pump → oil-starvation damage if neglected.

Fix / Workaround: Change wet belt on shortened interval; correct oil only; check oil/pump condition.

Repair cost: €400–€3000

Typically appears after: 80,000 km

Oil consumptionrecurring

Some PureTech units use noticeable oil.

Fix / Workaround: Monitor oil level; investigate top-ups.

Repair cost: €100–€1500

Typically appears after: 90,000 km

Wet timing belt (EB2) — verify setupcritical

Belt-in-oil cars: debris can block oil pickup → engine destruction. Late cars revised toward chain — confirm which.

Fix / Workaround: Confirm belt-vs-chain; frequent oil; belt on tighter schedule.

Repair cost: €500–€4000

Typically appears after: 60,000 km

Mileage Thresholds

After 100,000 km: Wet-belt cars: belt service is critical, not optional.
