The 2021 Lexus IS is a compact luxury sport sedan aimed at drivers who want sharp styling, confident handling, and Lexus-level comfort without moving up to a larger midsize platform. For 2021, the IS received a significant redesign with a stiffer structure, updated suspension tuning, and a more aggressive exterior that modernized its market position against rivals like the BMW 3 Series, Audi A4, and Acura TLX. It’s ideal for commuters who want a premium daily driver with strong long-term dependability, as well as enthusiasts drawn to the available V6 power. Overall, the 2021 IS balances sporty feel with the reputation for reliability that keeps Lexus high on many “best luxury brands” lists.

1) Engine choices: The IS 300 is available with a 2.0L turbocharged four-cylinder (241 hp) with rear-wheel drive, while another IS 300 configuration uses a 3.5L V6 (260 hp) paired with all-wheel drive. The IS 350 upgrades to a 3.5L V6 producing 311 hp, offered with rear-wheel drive or all-wheel drive. 2) Sport-focused chassis updates: The 2021 redesign brought revised suspension geometry, available adaptive variable suspension on select trims, and generally tighter body control than the prior model. 3) Modern safety tech: Lexus Safety System+ is included, featuring advanced driver-assistance technology such as pre-collision warning with automatic braking, lane departure alert, and adaptive cruise control (feature availability varies by configuration). 4) Interior and infotainment: A driver-oriented cabin with available larger center display and smartphone integration availability depending on build, plus strong material quality and supportive seating. 5) Available F SPORT upgrades: F SPORT packages can add sport seats, unique styling, performance-oriented tuning, and larger wheel/tire setups for a more aggressive look and feel.

Shoppers researching “2021 Lexus IS reliability” will generally find the model year to be above average for the class, but no vehicle is perfect. Here are some “2021 Lexus IS problems” and “2021 Lexus IS common issues” owners most often mention: 1) Infotainment glitches and connectivity problems: Some owners report screen freezing, lag, Bluetooth dropouts, or inconsistent smartphone integration. These issues can appear early in ownership and are often addressed through software updates, resets, or dealer reflashes. 2) Brake noise or feel complaints: A number of drivers note squeaks, grinding-type noises, or a somewhat grabby brake feel at low speeds, sometimes within the first 10,000–20,000 miles depending on driving conditions. In many cases it’s related to pad compound, rotor surface, or normal performance-brake behavior, but persistent noise should be inspected. 3) Wind noise and interior rattles: The redesigned body is solid, yet some owners report wind noise around the mirrors or door seals, along with occasional dash/trim rattles over rough roads. These concerns may show up at highway speeds or as miles accumulate, and can sometimes be improved with seal adjustments or trim isolation. 4) Tire wear on sport setups: Vehicles equipped with larger wheels and performance tires (often on F SPORT configurations) can experience faster tire wear, especially with aggressive driving or misalignment. Uneven wear may appear by 15,000–30,000 miles if rotations and alignment checks are skipped.
