Volvo S60

The MHEV base engine uses the same timing belt drive as all Drive-E T variants. 120,000 km change interval applies; on the MHEV also check the ISG belt tensioner.

Symptoms: No warning signs; squeaking on cool starts as early warning

All B4204T34 MHEV variants share the Drive-E base engine. The known piston ring and oil consumption problem of the early VEP4 generation also applies here, especially on vehicles prior to the production update in 2019.

Symptoms: Dropping oil level without visible leak, occasional blue smoke, consumption above 0.5 L/1,000 km

The belt-driven 48V integrated starter-generator sits on the accessory belt. At higher mileages the ISG belt and pulley can wear or cause vibration issues. Limited long-term data available.

Symptoms: Vibration on engine rocking, noise on cranking, ISG warning light in instrument cluster

The shared Drive-E base engine of the MHEV variants carries the same PCV weakness. A clogged crankcase ventilation increases oil pressure on seals, promotes oil consumption and can contaminate the ISG with oil.

Symptoms: Oil film in intake area, overpressure at oil cap, elevated oil consumption

Loose flange nuts on the rear toe link can abruptly worsen handling. Check for Volvo recall; affects S60 and V60 from September 2018.

MOT reports criticise above-average wear on tie rod ends, ball joints and suspension bushings at the front axle of the S60 III and V60 III. This occurs earlier with heavier engine variants or sporty driving.

On the S60 III and V60 III, the optional panoramic sunroof drainage channels block with leaves and dirt. Backed-up water enters the interior, often under the dashboard or onto the rear seat.
