The 2014 S80 is generally a solid platform, but the 3.0L turbo I6 (T6) can have catastrophic internal engine failures while the naturally-aspirated 3.2L is far more reliable. Transmission cooling and mount issues affect both variants.
Catastrophic Engine Failure - 3.0L Turbo I6 Only
Occasional · high severity
Typical onset: 80,000-140,000 mi
Symptoms: sudden loss of power under load, metallic knocking from engine bay, oil consumption increasing dramatically, white smoke from exhaust, check engine light with misfire codes
Fix: Piston ring land failure and cylinder scoring lead to complete engine rebuild or replacement. Common pattern: rings fail, oil burns, pistons scuff cylinders. Requires complete teardown - head gaskets, pistons, rings, crankshaft inspection, cylinder honing or sleeving, main and rod bearings. 25-35 labor hours for rebuild; short block replacement takes 18-22 hours.
Estimated cost: $8,000-14,000
Transmission Oil Cooler Failure
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: transmission fluid mixing with coolant (strawberry milkshake in reservoir), transmission slipping or harsh shifts, overheating transmission, coolant loss with no external leaks
Fix: Internal cooler in radiator develops leaks allowing cross-contamination. Requires radiator replacement, complete transmission fluid flush (multiple cycles), and often transmission filter/pan service. If caught early, transmission survives; if driven with contaminated fluid, transmission rebuild needed. 4-6 hours for cooler/flush only.
Symptoms: clunking when shifting from park to drive or reverse, excessive vibration at idle, shudder during acceleration, visible engine movement in bay during throttle blips
Fix: Hydraulic transmission mount collapses internally, allowing excessive powertrain movement. Requires lifting engine/trans slightly for access. OEM mount highly recommended over aftermarket. 2-3 hours labor.
Estimated cost: $500-800
Fuel Filter Clogging (High-Pressure)
Occasional · medium severity
Typical onset: 90,000-130,000 mi
Symptoms: rough idle and hesitation, loss of power especially under acceleration, long cranking before starting, intermittent stalling, fuel trim codes
Fix: High-pressure fuel filter inside tank gets restricted. Requires fuel tank drop for access - labor-intensive job. Filter not typically serviced on schedule, so many owners only discover when symptoms appear. 3-4 hours labor.
Estimated cost: $600-900
Timing Belt and Water Pump Service Neglect
Occasional · high severity
Typical onset: 105,000 mi (service interval)
Symptoms: no symptoms until catastrophic failure, coolant seepage from water pump weep hole (warning sign), squealing from accessory belt area
Fix: Both engines are interference designs - belt failure destroys valves and pistons. Volvo interval is 10 years/105k miles, whichever first. Job includes timing belt, water pump, tensioner, idler pulleys, accessory belts, coolant. Many used examples are approaching or past due. 6-8 hours labor for complete job.
Estimated cost: $1,800-2,500
PCV System Oil Trap Clogging
Common · low severity
Typical onset: 60,000-90,000 mi
Symptoms: rough idle, oil consumption, oil leaks from valve cover or rear main, whistling under hood, check engine light with lean codes
Fix: Oil separator/trap in PCV system clogs with sludge, creating crankcase pressure that forces oil past seals. Requires replacing oil trap assembly and associated hoses. Preventive maintenance item often overlooked. 2-3 hours labor.
Estimated cost: $400-650
Owner tips
Avoid the 3.0L turbo I6 in used examples unless complete engine service history is documented - the 3.2L naturally-aspirated is far more durable
Check transmission fluid color immediately on any used purchase - pink/red is good, brown or milky means walk away
Verify timing belt service history with receipts - this is non-negotiable at 100k+ miles on these interference engines
Replace PCV oil trap every 60-75k miles as preventive maintenance to avoid seal damage
Transmission mounts fail predictably - budget for replacement if buying over 70k miles
Buy the 3.2L with documented timing belt service and clean transmission fluid; avoid high-mileage turbo I6 models unless you have a spare $10k for an engine.

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.
