The 2014 Volvo S60 is a solid platform marred by catastrophic turbo engine failures on the T5 (2.5L I5) and T6 (3.0L I6) variants, plus transmission cooler issues that can destroy the gearbox if ignored. When they're good, they're great — when they're bad, you're looking at a complete engine rebuild.
Catastrophic Turbo Engine Failure (T5 & T6)
Occasional · high severityTypical onset: 80,000-140,000 mi
Symptoms: sudden loss of power and blue smoke on startup, metal shavings in oil, knocking or rattling from lower engine, check engine light with multiple misfires, oil consumption jumps dramatically
Fix: Turbocharger failure dumps metal debris into the oil system, destroying bearings and scoring cylinder walls. Requires complete engine rebuild or replacement: pistons, rings, main bearings, rod bearings, head work, often crankshaft machining. 30-50 labor hours depending on in-chassis rebuild vs. engine-out full replacement. Some shops swap in used engines to save cost but risk repeating the cycle.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Failure (Aisin AWF21 6-speed)
Common · high severityTypical onset: 70,000-110,000 mi
Symptoms: transmission fluid in coolant or vice versa (strawberry milkshake appearance), harsh shifting or slipping, overheating warnings, coolant loss with no visible leaks
Fix: Internal cooler in the radiator fails, allowing cross-contamination between coolant and ATF. If caught early (just the cooler), it's a radiator replacement plus multiple fluid flushes — 4-6 hours. If contamination circulates, the transmission is toast and needs replacement or rebuild. Add another 12-18 hours for trans R&R.
Estimated cost: $1,200-2,500 (cooler only); $4,500-7,000 (with transmission replacement)
Transmission Mount Collapse
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: clunking when shifting from park to drive or reverse, excessive vibration at idle, visible sagging or torn rubber on mount inspection
Fix: Hydraulic transmission mount fails, allowing drivetrain movement. Replacement requires lifting the engine slightly for access. 2-3 hours labor with OEM or upgraded polyurethane mount.
Estimated cost: $400-700
PCV System / Oil Trap Clogging (All Turbo Engines)
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: rough idle and hesitation, oil leaks from valve cover or turbo seals, white smoke from exhaust, turbo whistle or excessive boost pressure, oil in intake piping
Fix: Volvo's PCV oil trap clogs with sludge, causing crankcase pressure to blow seals and force oil past turbo seals. Requires oil trap replacement, new PCV hoses, often valve cover gasket. Neglecting this accelerates turbo failure. 3-4 hours labor. Critical preventive maintenance item.
Estimated cost: $600-1,000
Electronic Throttle Body Failure
Occasional · medium severityTypical onset: 90,000-130,000 mi
Symptoms: limp mode with reduced power, surging or hunting idle, check engine light with throttle position codes, car won't start or dies immediately
Fix: Throttle body actuator motor or position sensors fail. Not rebuildable on this platform — replacement only. Adaptive learning reset required after install. 1.5-2 hours labor.
Estimated cost: $500-900
Fuel Filter Clogging (Affected by Short Trips)
Occasional · medium severityTypical onset: 60,000-80,000 mi
Symptoms: hesitation under acceleration, rough running or stalling, difficulty starting when hot, loss of power on highway
Fix: In-tank fuel filter clogs prematurely if the car sees mostly short trips or sits for extended periods. Requires fuel pump module removal. 2-3 hours labor. Volvo doesn't specify replacement interval, but field data suggests 60-70k on city-driven cars.
Estimated cost: $400-700
Angle Gear Leaks (AWD Models Only)
Common · low severityTypical onset: 70,000-110,000 mi
Symptoms: fluid drips near rear of transmission, whining from rear differential area, AWD warning light
Fix: Angle gear (front-to-rear power transfer unit) seals leak, eventually starving the unit of fluid. Seal replacement is straightforward if caught early — 2 hours. If run low on fluid, internal damage requires angle gear replacement, adding another $800-1,500 in parts.
Estimated cost: $300-500 (seals); $1,500-2,500 (unit replacement)
Buy only with comprehensive service records proving PCV maintenance, or plan for a $10k engine rebuild lottery ticket — the S60 drives beautifully until it doesn't, and when it fails, it fails expensively.
