2015 ROLLS-ROYCE WRAITH

Typical onset: 40,000-80,000 mi

Symptoms: metallic knocking at idle that worsens with RPM, metal shavings in oil during changes, sudden loss of oil pressure, engine seizure in worst cases

Fix: Rod bearings fail due to inadequate oiling under high load or extended oil change intervals. Requires full engine-out teardown, crank polishing or replacement, new bearings, and often pistons/rings if debris circulated. 60-80 hours labor. Many owners opt for short block replacement instead of rebuild due to machine work costs and downtime.

Estimated cost: $25,000-45,000

Typical onset: 50,000-90,000 mi

Symptoms: visible oil seepage around turbo heat shields, blue smoke on startup or acceleration, loss of boost pressure, check engine light with underboost codes

Fix: Oil feed and return lines crack at fittings due to heat cycling. If ignored, turbos starve and fail internally. Catching leaks early: 8-12 hours to replace lines on both banks. Failed turbos add another 18-24 hours plus core charges.

Estimated cost: $3,500-6,000 (lines only), $12,000-18,000 (with turbo replacement)

Typical onset: 60,000-100,000 mi

Symptoms: harsh or delayed shifts, especially 2-3 and 3-4, transmission slipping under load, limp mode activation, fault codes for shift solenoids A, B, or E

Fix: The ZF 8HP90 valve body develops internal wear and solenoid sticking. Transmission must be dropped, valve body removed and rebuilt or replaced, fluid and filter changed. 14-18 hours labor. Rolls-Royce calibration software required for adaptation.

Estimated cost: $4,500-7,500

Typical onset: 30,000-70,000 mi

Symptoms: transmission fluid puddle under car, rapid loss of all transmission fluid, transmission overheating warning, no movement in any gear

Fix: Steel cooler lines rust through at brackets or corrode at crimp fittings, dumping 9+ quarts instantly. Requires line replacement, often transmission pan drop to check for debris, fluid flush, and sometimes valve body inspection if run dry. 6-10 hours labor depending on contamination.

Estimated cost: $2,200-4,000

Typical onset: 70,000-110,000 mi

Symptoms: white smoke from exhaust, coolant loss with no visible leaks, milky oil on dipstick, overheating under load, rough idle and misfires

Fix: V12 head gaskets fail from thermal stress or prior overheating. Requires heads-off on both banks, machining checks, new gaskets, bolts, and often timing components while apart. Engine-in service possible but tight. 50-65 hours labor. If heads are warped, add machine work or replacement head cost.

Estimated cost: $18,000-28,000

Typical onset: 60,000-100,000 mi

Symptoms: extended cranking before start, rough idle and misfires on multiple cylinders, loss of power and hesitation, fuel pressure fault codes, fuel smell in crankcase if injector seals leak

Fix: High-pressure fuel pump (mounted in valley) wears internally or injectors develop leaks at seals. Pump replacement requires intake manifold removal on both banks. Full injector set replacement often recommended. 16-22 hours labor for pump and injectors.

Estimated cost: $6,000-10,000
