The 2019 DBS Superleggera uses Aston's 5.2L twin-turbo V12 paired with a ZF 8-speed auto. While charismatic and potent, the engine suffers from catastrophic bearing and piston failures—often under 30,000 miles—due to oiling deficiencies and weak factory components, leading to full rebuilds that cost luxury-car money.
Premature Connecting Rod and Main Bearing Failure
Occasional · high severityTypical onset: 15,000-35,000 mi
Symptoms: Metallic knock or rattle at idle that worsens under load, Low oil pressure warning or fluctuating gauge, Metal shavings in oil during routine changes, Sudden catastrophic failure with no prior warning in some cases
Fix: Engine-out rebuild or short block replacement required. Factory oiling design leads to bearing starvation under high G-loads and spirited driving. Expect 40-60 labor hours for full teardown, bearing replacement, clearance checks, and reassembly. Upgraded bearings and improved oiling modifications strongly recommended to prevent repeat failure.
Estimated cost: $25,000-45,000
Piston Ring Land Cracking and Piston Failure
Occasional · high severityTypical onset: 20,000-50,000 mi
Symptoms: Excessive oil consumption (1 quart per 500-800 miles), Blue smoke on cold start or under hard acceleration, Misfires on one or more cylinders, Loss of compression detected during diagnosis
Fix: Requires full engine disassembly and piston replacement. Factory cast pistons have weak ring lands that crack under boost and heat cycling. Plan on 45-65 labor hours for engine removal, teardown, honing, piston/ring installation, and complete gasket refresh. Many shops recommend forged piston upgrade during repair.
Estimated cost: $22,000-38,000
Head Gasket Failure (Both Banks)
Rare · high severityTypical onset: 30,000-60,000 mi
Symptoms: Coolant loss with no visible external leaks, White smoke from exhaust, Overheating under load or in traffic, Milky oil or coolant in expansion tank
Fix: Both cylinder heads must be removed for gasket replacement and deck surface inspection. Warpage is common if overheating occurred. Budget 35-50 labor hours including coolant system flush, ARP stud upgrade recommended, and valve lash reset. Heads may need machining if warped.
Estimated cost: $15,000-24,000
Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 25,000-50,000 mi
Symptoms: Transmission fluid spots under vehicle near front subframe, Low fluid warning on dash (if equipped), Delayed or harsh shifting when fluid level drops, Visible seepage at crimped cooler line fittings
Fix: Factory crimped cooler lines fail at fittings due to heat cycling and vibration. Replacement involves raising vehicle, removing belly pans, and replacing lines with OEM or upgraded braided units. Requires fluid flush and refill. Approximately 3-5 labor hours.
Estimated cost: $1,200-2,200
Transmission Mount Deterioration
Occasional · low severityTypical onset: 30,000-60,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive driveline shunt during aggressive throttle application, Vibration felt through center console at idle
Fix: Rubber transmission mounts fail due to heat and torque loads from the V12. Requires lift access and support of transmission during swap. Straightforward replacement once access is gained. Typically 2-3 labor hours.
Estimated cost: $800-1,400
Fuel Filter Clogging (Early Fuel System Contamination)
Rare · medium severitySymptoms: Rough idle or stumbling under acceleration, Intermittent limp mode or reduced power warnings, Hard starting after sitting overnight, Fuel pressure fluctuations during diagnostic scan
Fix: Some early 2019 models had manufacturing debris in fuel tanks. In-tank fuel filter and pump module require removal. Tank often needs cleaning or replacement if heavily contaminated. Pump assembly replacement alone is 4-6 labor hours; tank cleaning adds 3-5 more.
Estimated cost: $2,500-5,000
Only buy if you have deep pockets and accept that a $20,000-$40,000 engine rebuild before 40,000 miles is a real possibility—this is a six-figure exotic with five-figure repair bills, not a daily driver.
