The 2013 V70 is Volvo's final-generation wagon built on the mature P3 platform. While generally reliable for daily use, it suffers from specific transmission cooling failures and catastrophic T6 engine issues that can turn expensive quickly.
Transmission Oil Cooler Failure (TF-80SC 6-Speed)
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Transmission fluid mixing with coolant (strawberry milkshake in reservoir), Erratic shifting or limp mode, Transmission overheating warnings, Coolant loss with no visible leaks
Fix: Replace transmission oil cooler and flush both cooling system and transmission. If caught early (no contamination), 4-6 hours labor. If delayed, transmission rebuild required adding 12-16 hours.
Estimated cost: $800-1,200 if caught early, $3,500-5,500 with transmission damage
T6 Engine Piston Failure (3.0L Turbo only)
Occasional · high severityTypical onset: 80,000-130,000 mi
Symptoms: Loud knocking or rattling from engine bay, Metal shavings in oil, Sudden loss of power, Check engine light with misfire codes, Catastrophic failure without warning in some cases
Fix: Known weak piston skirts on early T6 engines. Requires complete engine rebuild or replacement. 18-24 hours labor for short block replacement, 25-30 hours for full rebuild.
Estimated cost: $6,000-9,500
Transmission Mounts Deterioration
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Clunking when shifting from park to drive, Excessive vibration at idle, Transmission moves visibly under acceleration, Harsh engagement into gear
Fix: Upper and lower transmission mounts crack and separate. Replace both mounts simultaneously. 2-3 hours labor with proper lift access.
Estimated cost: $400-700
PCV System Clogging (3.2L I6)
Common · medium severityTypical onset: 60,000-90,000 mi
Symptoms: Oil consumption (1 quart per 1,000 miles), Oil in intake tract or throttle body, Rough idle when cold, Whistling sound from engine bay, Oil leaks from valve cover area
Fix: Oil trap (PCV box) clogs causing crankcase pressure. Replace oil trap, PCV hoses, and clean throttle body. 3-4 hours labor, preventive replacement recommended every 60k.
Estimated cost: $500-800
Fuel Filter Housing Corrosion
Occasional · medium severityTypical onset: 80,000-120,000 mi
Symptoms: Fuel smell under vehicle, Hard starting after sitting, Visible fuel weeping from filter area, Check engine light with lean codes
Fix: Plastic fuel filter housing cracks or corrodes where it mounts. Replace entire filter assembly with updated metal-reinforced version. 1.5-2 hours labor.
Estimated cost: $300-500
Angle Gear Seal Leaks (AWD models)
Common · low severityTypical onset: 70,000-100,000 mi
Symptoms: Gear oil dripping from rear of transmission area, Oil spots on driveway centered under vehicle, Low AWD fluid warnings on later models
Fix: Input and output seals on angle gear (transfer case) fail. Replace seals and top off Haldex fluid. 2-3 hours labor, can be done during transmission service.
Estimated cost: $400-650
Buy the 3.2L non-turbo if you want reliability; avoid the T6 unless you have detailed service records and $8k in reserve for potential engine work.
