The Lemon Index
Maserati's 3.0 L twin-turbo 90° V6 in the MC20 and GranTurismo (2024), model years 2022–2025. YouTube likes the 2024 best.
A safer bet: YouTube owner tone 57/100, #15 of 165 engines with a YouTube study (in the top third); 1 engine-related recall on record.
Reliability by year
Not enough complaints to chart. We found no government complaints we can tie to this engine's cars. Performance versions are mostly filed under their base model (a Shelby GT500 is filed as a Mustang), so we only count complaints whose model name or the owner's own words tie them to this engine, and lead with YouTube, recalls and the automaker's repair notes.
YouTube videos are most positive about the 2024 (58) and least about the 2022 (56); 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.
All the numbers, year by year
