Lotus bulletin sb_2021_06_DTC
What it saysThere is often inconsistent or insufficient information received from dealers when reporting ECU and TCU related faults. NHTSA’s full summary ↓
Lotus filed this with NHTSA as a service bulletin dated Jun 16, 2021, received Jul 5, 2021, about the engine. It names 5 model years (2016–2020). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Source: NHTSA, 49 CFR 579.5Is Lotus sb_2021_06_DTC a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the sb_2021_06_DTC repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.

The manufacturer filed it against 5 model years: 2020 Lotus Evora, 2018 Lotus Evora, 2017 Lotus Evora, 2016 Lotus Evora, 2019 Lotus Evora. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
