2016 ASTON MARTIN DB11

Typical onset: 15,000-40,000 mi

Symptoms: Metallic knocking or rattling from bottom end, especially on cold start, Metal shavings in oil during changes, Sudden loss of oil pressure leading to immediate shutdown, Check engine light with low oil pressure codes

Fix: Complete engine-out teardown required. Typically needs new crankshaft, all bearings (mains and rod), often pistons and rods if debris circulated. 60-80 hours labor for engine removal, rebuild, and reinstallation. Some shops recommend full short block replacement to avoid liability. This is a known defect in early 5.2L V12 twin-turbo engines related to oil starvation during spirited driving and inadequate bearing clearances.

Estimated cost: $35,000-65,000

Typical onset: 30,000-60,000 mi

Symptoms: Transmission fluid puddles under car, typically passenger side, Burning smell after highway driving, Transmission warning light or limp mode in hot weather, Low fluid level on dipstick check

Fix: Oil cooler lines corrode where they meet the cooler housing due to dissimilar metals and road salt exposure. Cooler itself often weeps at seams. Requires removing undertray and sometimes front subframe components for access. 6-9 hours labor. OEM parts only—aftermarket doesn't exist yet.

Estimated cost: $2,800-4,200

Typical onset: 40,000-70,000 mi

Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive vibration at idle in Drive, Visible sagging of transmission tailhousing, Grinding sensation through shifter during acceleration

Fix: The rear transmission mount uses a hydraulic design that fails prematurely, especially on V12 models with more torque. Trans must be supported while mount is replaced. 4-6 hours labor. Aston revised the part twice; ensure you get the latest supersession or it'll fail again in 20k miles.

Estimated cost: $1,800-2,600

Typical onset: 25,000-50,000 mi

Symptoms: Rough running, misfires, or no-start condition, Fuel smell in cabin or trunk area, Check engine light with multiple cylinder misfire codes, Visible fuel weeping from filter housing in trunk

Fix: Fuel filter housing cracks and allows unfiltered fuel into the system, contaminating injectors. Requires new filter housing, fuel lines, and often injector cleaning or replacement on affected bank. If debris reached injectors, add 8-12 hours for injector R&R and coding. Located in trunk, relatively accessible but time-consuming due to fuel system bleed procedures.

Estimated cost: $2,200-5,500

Symptoms: Screen freezes on startup, requires battery disconnect reset, Bluetooth refuses to pair or constantly disconnects, Navigation shows incorrect location or fails to load maps, Climate control unresponsive through touchscreen

Fix: This is Mercedes' COMAND system, which doesn't play well with Aston's bespoke wiring. Software updates help but don't cure it. Dealers can reflash (2 hours), but issue often recurs. Some units need full head unit replacement under warranty extension. Out of warranty, you're looking at $3,500+ for new head unit. Most owners just live with periodic resets.

Estimated cost: $200-3,800

Typical onset: 35,000-65,000 mi

Symptoms: Clunking over bumps from rear of car, Wandering feeling in rear end during lane changes, Vibration through chassis at highway speeds, Visible cracking in rubber bushings during inspection

Fix: Differential carrier bushings are under-spec'd for the power and car's weight. Requires subframe drop or partial drop depending on which bushings failed. 8-12 hours labor. Upgraded polyurethane bushings available from aftermarket but sacrifice some ride quality. OEM replacements will fail again at similar intervals.

Estimated cost: $2,400-3,800
