The 2015 XC60 is a solid premium crossover, but the T6 3.0L inline-six has catastrophic piston/ring failure issues that can grenade the engine, while the 2.0L T5/T6 Drive-E four-cylinders are generally robust. Transmission mounts wear early and transmission oil cooler leaks are common across all variants.
3.0L T6 Piston Ring/Piston Failure (Catastrophic)
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: excessive oil consumption (1 qt per 1,000 mi or worse), blue smoke on cold start, rough idle and misfires, sudden catastrophic loss of compression, metal shavings in oil
Fix: Pistons and rings disintegrate due to design flaw and carbon buildup. Requires complete engine rebuild or short block replacement. 25-35 hours labor. Many opt for used engine swap instead at 15-20 hours.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: transmission fluid puddles under vehicle, transmission overheating warnings, burnt transmission fluid smell, erratic shifting when hot
Fix: Cooler lines corrode where they connect to radiator or frame. Replace lines and top off fluid. 2-3 hours labor. Check transmission condition if driven hot.
Estimated cost: $400-700
Transmission Mount Failure
Common · low severity
Typical onset: 50,000-90,000 mi
Symptoms: clunk when shifting from Park to Drive, vibration at idle, excessive engine movement on acceleration, knocking from engine bay over bumps
Fix: Rubber mount separates or cracks. Replace transmission mount assembly. 1.5-2 hours labor. Inspect other motor mounts while in there.
Estimated cost: $300-500
Fuel Filter Clogging (High-Pressure Direct Injection)
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: hard starting especially when hot, rough idle and hesitation, poor acceleration and power loss, check engine light for fuel trim/pressure codes
Fix: In-tank high-pressure filter clogs with sediment. Requires fuel tank drop and pump module service. 3-4 hours labor. Replace with OE Volvo part only.
Estimated cost: $600-900
PCV System Oil Trap Clogging
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: whistling or hissing from engine bay, rough idle, oil leaks from various seals, check engine light for lean codes, oil in intake system
Fix: Oil separator box under intake manifold clogs and creates vacuum leaks or positive crankcase pressure. Replace PCV oil trap assembly and hoses. 2-3 hours labor on four-cylinders, 4-5 on six.
Estimated cost: $500-900
Front Lower Control Arm Bushings
Occasional · low severity
Typical onset: 70,000-110,000 mi
Symptoms: clunking over bumps, wandering steering, uneven tire wear on inside edges, steering wheel off-center after alignment
Fix: Front lower arm bushings tear and cause alignment drift. Replace both lower control arms as assemblies. 3-4 hours labor including alignment.
Estimated cost: $800-1,200
Owner tips
Absolutely avoid the 3.0L T6 inline-six unless full engine rebuild history is documented — this engine has endemic piston ring failure
Change transmission fluid every 40,000 mi despite 'lifetime fill' claim — Aisin TF-80SC is sensitive to degraded fluid
Use Top Tier fuel and replace fuel filter proactively at 80k mi to prevent high-pressure pump damage
Check PCV oil trap every 50k mi and replace preventively at 75k — cheap insurance against vacuum leaks and oil consumption
Inspect transmission cooler lines annually for corrosion if in salt-belt states
Buy the 2.0L four-cylinder T5 or Drive-E models only; the 3.0L T6 is a financial time bomb that will cost more than the vehicle's worth to repair.

Volvo Cars of N.A., LLC (Volvo) is recalling certain 2008-2016 V70 and XC70, 2007-2016 S80, 2011-2018 S60 and V60, 2016-2018 S60 Cross Country, 2014-2020 S60L, 2009-2015 S80L, 2009-2016 XC60 and 2015-2018 V60 Cross Country vehicles. The flexible steel cable that connects the seat belt to the front outboard seating positions may fatigue over time, causing the seat belt to not secure the occupant in the event of a crash.
Consequence: An unsecured occupant has an increased risk of injury in the event of a crash.
Remedy: Volvo will notify owners, and dealers will replace the seat belt anchor cable for both front seats. The recall began December 10, 2020. Owners may contact Volvo customer service at 1-800-458-1552. Volvo's number for this recall is R10029.
