Known issues on the 2021 Envision. The 2021 Envision has 2 recalls on the federal record, both settled with software. On certain 2021 Envision vehicles, the daytime running lights might stay lit with the headlights on, creating glare; the body control module was updated by a dealer or over the air. Certain 2021 Envision vehicles also had a communications gateway module that mishandled a lost link to the air bag sensing module, so the air bag warning light might not come on when needed. Owners made 23 complaints: fuel and propulsion 6, electrical 5, powertrain 5, engine 2 and tires 2; 2 reported a crash. Lighting and air bag wiring diagrams and diagnostics apply.
