Model years from EPA version lists. Only years we have a car page for.
Reliability by year
Not enough complaints to chart. Owners filed 7 complaints with the government that we can tie to this engine's cars, 2016–2026, about any part of the car. 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 (65) and least about the 2016 (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.
