The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 201 complaints with NHTSA since 2015. 13 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
Upon startup in cold weather conditions, a brief but loud grinding/rattling sound will occur. The noise is related to an inadequate spring inside of the intake camshaft gear which will not push a small cylinder in place to lock the intake camshaft gear in place.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota 24TC08 a recall?
No. A service campaign 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 24TC08 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.

The manufacturer filed it against 5 model years: 2024 Toyota Corolla, 2023 Toyota Corolla, 2023 Toyota Prius, 2024 Toyota Prius Prime, 2023 Toyota Prius Prime. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
