2016 ROLLS-ROYCE WRAITH

Typical onset: 50,000-80,000 mi

Symptoms: Rough idle or flashing CEL with multiple misfire codes (P0300-P0312), Loss of power on acceleration, especially under boost, Excessive oil consumption (more than 1 qt per 1,000 mi), Ticking or knocking noise from valve train or cylinder bank

Fix: Direct-injection engines suffer intake valve carbon buildup; severe cases cause hot spots that crack piston ring lands or score cylinder walls. Walnut blasting intakes runs 8-12 hours labor. If pistons/rings are damaged, expect engine-out teardown: 40-60 hours labor plus pistons, rings, honing, head gaskets. Some shops opt for short-block replacement (60-80 hours) to avoid machine work liability.

Estimated cost: $18,000-45,000

Typical onset: 60,000-100,000 mi

Symptoms: Transmission fluid dripping from bell housing area or passenger side of engine bay, Burnt ATF smell after highway runs, Intermittent harsh shifts or slipping when fluid runs low, Low transmission fluid warning on iDrive (if equipped with sensor)

Fix: Factory cooler lines corrode at crimps or cooler itself cracks at mounting tabs. Requires partial exhaust removal and sometimes subframe drop for access. Replace cooler, lines, and top off ZF LifeguardFluid 8 (8-10 quarts). Labor runs 6-9 hours depending on subframe work.

Estimated cost: $2,200-3,800

Typical onset: 70,000-110,000 mi

Symptoms: Clunk or thud during D-to-R or R-to-D engagement, Vibration through floorboard at idle in gear, Driveline shudder during moderate acceleration (1,500-2,500 RPM), Visible sag or torn rubber on transmission mount inspection

Fix: Fluid-filled mounts fatigue from V12 torque and weight. Replacing both transmission mounts plus rear engine mount as a set prevents comebacks. Labor is 4-6 hours with exhaust/heat shield removal. Use OEM mounts; aftermarket units fail within 20k mi.

Estimated cost: $1,800-2,800

Typical onset: 40,000-70,000 mi

Symptoms: Long crank or no-start after sitting overnight, Stumble or hesitation under hard acceleration, Fuel pressure faults (P0087, P0088) logged in DME, Sudden loss of power followed by limp mode

Fix: In-tank low-pressure pump clogs or high-pressure pump (driven off exhaust camshaft) wears its roller followers, dropping rail pressure below 1,800 psi. Diagnosing requires scan tool live data. Fuel filter lives in tank and should be replaced every 50k mi (often skipped). HPFP replacement: 6-8 hours. In-tank filter/pump module: 8-10 hours plus tank drop.

Estimated cost: $2,500-5,500

Typical onset: 80,000-130,000 mi

Symptoms: Delayed or harsh 2-3 or 3-4 upshifts, Transmission fault warning on dash with gear display flashing, Stuck in failsafe gear (usually 5th or 7th only), Mechatronic sleeve wear codes (17E8, 17EA series) stored

Fix: ZF mechatronic sleeve wears or individual shift solenoids stick from ATF breakdown (common if fluid never changed). Repair requires pan drop, valve body removal, solenoid pack replacement, and adaptive reset. Specialist techs complete in 8-12 hours; general shops often send out or replace entire valve body (adds $3k parts).

Estimated cost: $3,500-7,000

Typical onset: 80,000-150,000 mi

Symptoms: White smoke from exhaust (coolant entering cylinders via head gasket), Rapid coolant loss with no external leaks, Knocking or rod bearing noise, worsening under load, Metallic debris in oil filter or pan during service

Fix: Owners skipping oil changes or ignoring coolant leaks face head gasket failure (coolant seeps into cylinders, hydrolocks engine) or spun main/rod bearings. Both require engine removal. Head gaskets both banks: 50-60 hours. Bottom-end work (bearings, crank): 60-80 hours. Most shops quote short-block or long-block replacement to limit liability; used N74 cores run $12-18k, rebuilt long-blocks $25-35k.

Estimated cost: $35,000-65,000
