Lotus filed this with NHTSA as a service bulletin dated Aug 29, 2024, received Sep 4, 2024, about the power train. It names 1 model year (2024). 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.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationImportant information for a temporary recovery procedure for the Central Powertrain Controller (CPC Module). Updated software was recently released for the CPC module, but because of reported failures to complete the programming successfully when trying to upload the software, which had left some vehicles immobile* and CPC recovery cannot be achieved without performing a CPC RELOAD, therefore this update option has been temporarily disabled. *Because the CPC module in a partially programmed state cannot operate or communicate correctly with the vehicle networks. ACTION It is expected to re-enable this feature soon, but once enabled, if there is a failure to complete the programming successfully during an upgrade, please contact Emira Support (detailing on an LCMS ticket that this request requires LTIL Emira Support assistance).

Common questions
Source: NHTSA, 49 CFR 579.5Is Lotus TSB-131-24024 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 TSB-131-24024 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.
Which vehicles does TSB-131-24024 cover?
The manufacturer filed it against 1 model year: 2024 Lotus Emira. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
