The Lemon Index
BMW's 3.0 L twin-turbo inline-6 in the 2 Series, 4 Series, M3, X3, X4, model years 2020–2026. YouTube likes the 2022 best.
A safer bet: YouTube owner tone 56/100, #24 of 165 engines with a YouTube study (in the top third); no engine-related recall on record, 1 known issue listed below.
Reliability by year
YouTube videos are most positive about the 2022 (59) and least about the 2023 (54); neighboring years share many of the same videos, so small gaps mean little.
Owner score = the whole car's Lemon Index where this was its only engine that year; a gray dot means the model shared engines, so the number isn't this engine's alone. How we count
How each number is matched to the engine: (a) complaints filed under a version name that used only this engine that year (e.g. "335I"); (b) the model had only this engine that year, so its Lemon Index (complaints per car sold vs the average car) applies to every car with this engine; "all engines combined" = the model had several engines under one name, so its number is not this engine's alone. Owner complaints cover the whole car (brakes, air bags, electrics ...), not only the engine. None of these is a failure rate. YouTube tone = how positive the videos are, 0–100, from titles and transcripts that name the engine or a version that used it. A video whose title names no model year counts toward every year of its generation, so neighboring years share most of their videos.

In the US: the 2 Series, 4 Series, M3, X3, X4, model years 2020–2026. See the version table for each one.
Is the S58 reliable?
Mostly yes. YouTube owner tone 56/100, #24 of 165 engines with a YouTube study (in the top third); no engine-related recall on record, 1 known issue listed below. The most owner complaints (about any part of the car) filed under version names that used this engine were for the 2021 (3). Counts follow sales, so this is not a failure rate. Government complaints are filed by model and year, not engine, and they cover the whole car, so none of these numbers is an engine failure rate. We only credit a number to this engine where the version name or the model year leaves no doubt. Have any used car inspected.
How much horsepower does the S58 make?
BMW rated it at 453 to 543 hp in US versions, depending on the car and year.
