The 2015 S60 is a solid mid-size sedan, but the turbocharged engines—especially the T5 and T6 variants—have known piston/ring issues that can escalate to catastrophic failure. Transmission cooling and PCV system maintenance are critical to longevity.
Piston Ring Failure / Engine Rebuild (T5/T6 engines)
Occasional · high severity
Typical onset: 80,000-130,000 mi
Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Blue smoke on startup or acceleration, Loss of power, misfires, Eventually catastrophic rod knock or seized engine
Fix: Full engine rebuild or short block replacement required. Piston rings fail due to carbon buildup and wear in high-boost conditions. 20-30 labor hours for short block swap, more for full rebuild. Some early failures covered under extended Volvo warranty (ended ~2020), but most post-warranty owners pay out-of-pocket.
Estimated cost: $6,000-12,000
Transmission Oil Cooler Failure
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Transmission slipping or delayed engagement, Pink/milky transmission fluid (coolant contamination), Check engine light with trans codes, Overheating or rough shifts
Fix: The internal transmission oil cooler (inside the radiator or separate unit) can crack, mixing coolant and ATF. Requires cooler replacement, full trans fluid flush, and often filter change. If caught early, trans survives; if driven with contaminated fluid, you're looking at trans rebuild. 3-5 labor hours for cooler and flush.
Estimated cost: $800-1,500
PCV System Clogging (Oil Trap)
Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Rough idle, intermittent stalling, Oil leaks from valve cover or turbo seals, Whistling or hissing from engine bay, Check engine light (often P0171/P0174 lean codes)
Fix: Volvo's PCV oil trap clogs with sludge, causing vacuum leaks and crankcase pressure issues. Replace oil trap, associated hoses, and breather box. Should be done proactively at 80k to prevent turbo and seal damage. 2-3 labor hours.
Estimated cost: $400-700
Front Door Latch Failure
Occasional · medium severity
Symptoms: Door won't open from inside or outside, Door ajar warning with door closed, Lock/unlock cycles repeatedly, Manual override cable needed to exit
Fix: Electronic door latch mechanism fails (covered under NHTSA recall for some VINs, check yours). If recall already done or out of scope, you're paying retail. Requires door panel removal and latch replacement. 1.5-2 labor hours per door.
Estimated cost: $350-600
Transmission Mount Failure
Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking on acceleration or deceleration, Vibration at idle in gear, Excessive engine movement visible from engine bay
Fix: Upper transmission mount (torque mount) deteriorates, especially with spirited driving. Straightforward replacement, but requires lifting the drivetrain slightly. 2-3 labor hours.
Estimated cost: $400-650
Fuel Filter Clogging (Turbo Models)
Occasional · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Hard starting, long cranking, Loss of power under load, Rough running, hesitation, Fuel pump whining
Fix: In-tank fuel filter and pump assembly can clog or fail, especially if bad gas or infrequent filter changes (Volvo recommends every 60k, often ignored). Requires fuel tank drop. 3-4 labor hours.
Estimated cost: $600-1,000
Owner tips
Change PCV oil trap preventively at 75-80k miles—this single item prevents thousands in turbo and seal repairs.
Use quality full-synthetic oil (Volvo spec) and change every 5k miles to combat piston ring carbon buildup.
Check transmission fluid color regularly; any pink/milky appearance means immediate cooler inspection.
Verify your VIN for open recalls (door latch especially) before purchase—some dealers still honor them.
A comfortable, well-handling sedan, but avoid high-mileage T5/T6 engines without proof of meticulous maintenance—piston issues are expensive and common enough to be a deal-breaker.
