The Lemon Index
BMW's 6.75 L naturally aspirated V12 in the Rolls-Royce Phantom, model years 2010–2017. YouTube likes the 2010 best.
Middle of the pack: YouTube owner tone 48/100, #93 of 165 engines with a YouTube study (in the middle third); 1 engine-related recall on record.
Reliability by year
Not enough complaints to chart. Owners filed 1 complaint with the government that we can tie to this engine's cars, 2010–2017, about any part of the car. Supercars sell in small numbers, so we show YouTube, recalls and the automaker's repair notes instead.
YouTube videos are most positive about the 2010 (51) and least about the 2017 (45); neighboring years share many of the same videos, so small gaps mean little.
How we count: owner complaints only where the car's name and year leave no doubt; YouTube tone from videos that name this engine or its cars. How we count
Owner complaints (NHTSA) are filed by model and year, not engine. We count one for this engine only when the model name and year had no other engine (e.g. "488 GTB", "GT-R"), or when the owner's own words name a version that had only this engine that year (Z06, ZR1, Hellcat, GT500 ...). They cover the whole car (wheels, air bags, electrics ...), not only the engine, and none of them is a failure rate. We chart them only for engines with 30 or more, over 3 or more years. YouTube tone = how positive the videos are, 0–100, from titles and transcripts (praise vs trouble words, the title counts 3 times), weighted by views; a year needs at least 3 videos' worth. A video counts for this engine when its title names the engine or a car that only had this engine in the years it names; a video whose title names no model year counts toward every year of that car, so neighboring years share most of their videos.

NHTSA recalls by model and year. A recall counts here when every confirmed version of that model-year had this engine, or the recall names it. Check a car's VIN for its own open recalls.
Engine problems BMW told dealers about
BMW sent dealers 8 repair notes about the engine on these cars, including:
- Engine MIL light is illuminated and fault 12BF08 Lambda probe, from meager to fat slow reaction
NHTSA manufacturer communications (technical service bulletins), matched by model name and year like the complaints, engine-related ones only. A repair note is not a recall: ask a seller whether it was done.
