The 2016 S60 is a solid platform hampered by predictable Volvo issues: transmission oil cooler failures, PCV system problems on turbo fours, and aging P3-platform electrical gremlins. The T5/T6 four-cylinders are more problematic than the older five/six-cylinder models.
Transmission Oil Cooler Failure
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Transmission fluid mixing with coolant (strawberry milkshake in expansion tank), Harsh shifting or slipping, Transmission overheating warnings, Coolant loss with no visible leaks
Fix: Replace transmission oil cooler, flush both cooling system and transmission completely, sometimes requires transmission replacement if contamination is severe. 4-6 hours labor for cooler only, 12-18 hours if trans needs replacement.
Estimated cost: $1,200-$1,800 (cooler/flush only), $4,500-$7,000 (with transmission replacement)
PCV System Failure (2.0L Turbo I4 Engines)
Common · medium severityTypical onset: 70,000-120,000 mi
Symptoms: High oil consumption (1 quart per 1,000 miles or worse), Rough idle and misfires, Check engine light with lean/rich codes, Oil residue in intake tract, Whistling noise from engine bay
Fix: Replace PCV breather box assembly, oil trap, and all associated hoses. Often requires intake manifold removal. 3-5 hours labor. Delay causes turbo and piston ring damage.
Estimated cost: $800-$1,400
Engine Bearing and Piston Failure (2.0L T5/T6)
Occasional · high severityTypical onset: 80,000-130,000 mi
Symptoms: Rod knock or metallic rattling at idle, Sudden loss of power, Metal shavings in oil, Catastrophic failure without warning in some cases
Fix: Usually requires complete engine rebuild or replacement. Root cause often tied to ignored PCV issues causing carbon buildup and oil starvation. 20-30 hours labor for rebuild, 12-16 hours for used engine swap.
Estimated cost: $6,000-$9,500 (rebuild), $4,500-$6,500 (used engine)
Transmission Mounts (All Models)
Common · low severityTypical onset: 70,000-110,000 mi
Symptoms: Clunking when shifting from park to drive, Excessive vibration at idle, Shudder during acceleration, Visible sagging or torn rubber on inspection
Fix: Replace transmission mount(s). Upper mount most common failure point. 1.5-2.5 hours labor.
Estimated cost: $350-$650
Fuel Pump Control Module Failure
Occasional · high severitySymptoms: No-start condition with no fuel pressure, Intermittent stalling while driving, Check engine light with fuel system codes, Cranks but won't fire
Fix: Replace fuel pump control module (located under vehicle near fuel tank). Often misdiagnosed as fuel pump itself. 1.5-2 hours labor.
Estimated cost: $600-$900
Electronic Throttle Body Failure
Occasional · medium severityTypical onset: 90,000-140,000 mi
Symptoms: Limp mode (reduced power), Erratic idle speed, Check engine light with throttle position codes, Throttle response lag or surging
Fix: Replace throttle body assembly. Cleaning rarely works long-term on these. Requires VIDA software for proper adaptation. 1.5-2 hours labor.
Estimated cost: $550-$850
Headlight Wiring Harness Corrosion
Occasional · low severityTypical onset: 80,000+ mi
Symptoms: Intermittent headlight operation, Flickering lights, Bulb-out warnings with good bulbs, Complete headlight failure one side
Fix: Repair or replace corroded connector at headlight assembly. Sometimes requires harness section replacement. 1-2 hours labor per side.
Estimated cost: $250-$500
Buy the T5/T6 only if full service records show PCV work was done and transmission was maintained; otherwise stick with the older five-cylinder models or budget heavily for repairs.
