Reliability, common problems and owner reviews for the Nissan Qashqai 2.0 petrol (MR20DE). Check this before you buy used.
The strongest Qashqai petrol and a genuinely solid block — but 'reliable' doesn't mean problem-free. Two things catch owners out: it has NO hydraulic lifters, so valve clearances need manual adjustment roughly every 100,000 km or a ticking develops; and the exhaust manifold/catalytic converter assembly is prone to cracking from around 50,000-80,000 km, causing a loud exhaust rattle. Address those two and it's a dependable engine.
Same engine, other cars
This is the same physical engine (MR20DE) sold under different names across brands. Reliability is broadly shared — cross-check these:
Known Issues
Unlike most modern engines, the MR20DE uses mechanical bucket tappets with no automatic lash adjustment. If clearances aren't checked/adjusted, a noticeable ticking/tapping develops from the top of the engine and can accelerate cam/follower wear.
Fix / Workaround: Have valve clearances checked and adjusted roughly every 100,000 km (60,000 miles) — ask for proof in service history.
Repair cost: €100–€300
Typically appears after: 100,000 km
The exhaust manifold (integrated with the catalytic converter on this engine) is known to crack from around 50,000-80,000 km, producing a loud ticking/rattling exhaust note, often worse on cold start, and can trigger a catalyst-efficiency fault (P0420).
Fix / Workaround: Listen for a 'tinny' rattle/tick from the exhaust side on cold start; replace the manifold/cat assembly if cracked.
Repair cost: €250–€700
Typically appears after: 60,000 km
A subset of J10 2.0 petrol owners report misfire-like rough idle, stumbling on pull-away, and occasional stalling — commonly traced to coil packs, MAF sensor, or EGR valve fouling rather than the engine internals.
Fix / Workaround: Test drive cold and warm; if rough idle present, check coil packs, MAF and EGR before assuming a major fault.
Repair cost: €50–€300
Less prone to chain stretch than the 1.6 HR16, but on neglected, high-mileage examples (150,000 km+) the timing chain can start rattling on cold start with rough idle and minor power loss.
Fix / Workaround: A cold-start rattle that clears within a few seconds is normal on some units; persistent rattle or rough idle warrants a chain/tensioner inspection.
Repair cost: €300–€900
Typically appears after: 150,000 km
Many are paired with Nissan's CVT, which has its own well-documented reliability concerns separate from the engine — confirm smooth operation and fluid service history.
Fix / Workaround: Check CVT on test drive (shudder, whine, delayed engagement); confirm fluid changes.
Repair cost: €0–€2500
Mileage Thresholds
After 60,000 km: Exhaust manifold/cat assembly starts to be at risk of cracking — listen for a new exhaust tick/rattle.
After 100,000 km: Valve clearances should be checked/adjusted (no hydraulic lifters) — ticking from the top of the engine if overdue.
After 150,000 km: Timing chain wear becomes more likely — cold-start rattle and rough idle worth investigating.
Fault Codes to Scan
Pre-Purchase Checklist
- ☐Cold start the engine and listen for a tapping/ticking from the top end (valve clearance) and a separate rattly exhaust tick (manifold/cat crack)
- ☐Ask for service records showing valve clearance adjustment around 100,000 km
- ☐Check for stored P0420 codes or a recently replaced exhaust manifold/cat
- ☐Test drive for rough idle, hesitation or stumble on pull-away
- ☐If CVT-equipped: check for shudder/whine and fluid service history
- ☐Otherwise a robust block — minimal risk of major engine failure if these items are addressed
