The 2017 Vantage with the 4.7L V8 is the tail end of a platform that debuted in 2005. These are hand-built exotic sports cars with legitimately brilliant handling, but the aging design shows its limitations in transmission cooling, engine oil consumption, and wear patterns that become expensive once the powertrain hits higher mileage or spirited use.
Transmission Oil Cooler Failure and Overheating
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission temperature warning light on dash, Harsh or delayed shifts when hot, especially in Sport mode, Burnt transmission fluid smell or dark ATF on dipstick, Limp mode activation during aggressive driving or hot weather
Fix: Replace transmission oil cooler, flush and refill ATF, inspect transmission mounts simultaneously as they often fail around same time. 6-8 hours labor depending on access and whether you drop the undertray or lift the car.
Estimated cost: $2,200-3,800
Excessive Oil Consumption and Piston Ring Wear
Occasional · high severityTypical onset: 60,000-100,000 mi
Symptoms: Burning through 1+ quart of oil every 1,000-1,500 miles, Blue smoke on cold start or deceleration, Fouled spark plugs, misfires on cylinders 2, 4, 6, or 8, Loss of power and rough idle as rings deteriorate
Fix: Requires engine-out service for piston ring replacement or full rebuild depending on cylinder bore condition and bearing wear. Expect 40-60 hours labor for a proper rebuild with machine work, new rings, bearings, gaskets, and seals. Many owners opt for short block replacement instead if cylinders are scored.
Estimated cost: $18,000-28,000
Transmission Mount Failure
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking or banging noise under hard acceleration or deceleration, Excessive drivetrain movement felt through cabin, Vibration at idle in Drive or Reverse, Difficulty engaging gears smoothly
Fix: Replace failed hydraulic transmission mount. Often done in conjunction with transmission cooler service since access overlaps. 3-4 hours labor, straightforward job but part is expensive OEM.
Estimated cost: $1,200-1,800
Fuel Filter Clogging and Fuel System Contamination
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Rough running, hesitation, or stumbling under load, Check engine light with fuel trim codes (P0171, P0174), Hard starting or extended cranking, especially when hot, Loss of power above 4,000 RPM
Fix: Replace in-tank fuel filter and pump assembly, inspect fuel lines for corrosion or debris. Aston fuel systems are sensitive to contamination and old gas. 4-5 hours labor as tank must be dropped.
Estimated cost: $1,400-2,200
Head Gasket Failure (Both Banks)
Rare · high severityTypical onset: 80,000-120,000 mi
Symptoms: Coolant loss with no visible leaks, White smoke from exhaust, sweet smell, Milky oil on dipstick or oil cap, Overheating, especially under load or in traffic, Rough idle and misfires if coolant enters cylinders
Fix: Requires heads-off service, machine shop work for resurfacing, new head gaskets, ARP studs recommended, timing components, and all associated seals. 25-35 hours labor depending on whether heads need significant work. Often uncovers additional wear requiring full rebuild.
Estimated cost: $12,000-18,000
Main and Rod Bearing Wear from Aggressive Driving
Occasional · high severityTypical onset: 70,000-110,000 mi
Symptoms: Knocking or ticking noise from lower engine, especially on cold start, Metal shavings or glitter in oil during changes, Low oil pressure warning at idle when hot, Sudden catastrophic failure if ignored—spun bearing, grenaded motor
Fix: Engine-out teardown, inspect crank journals, replace all main and rod bearings, possibly regrind crank if journals are scored. Often combined with full rebuild if oil consumption is also present. 50+ hours labor for comprehensive service.
Estimated cost: $16,000-26,000
Buy one only if you have a $20k engine-rebuild fund set aside and access to a specialist who knows these V8s—spectacular to drive, but the powertrain is a ticking time bomb past 70k miles without meticulous records.
