Toyota service campaign 21TG01
Toyota filed this with NHTSA as a service campaign dated Jun 18, 2025, received Dec 13, 2021, about the electrical system — 10 documents under this number: 21TG01 Dealer Le, 21TG01_Dealer_Da. It names 3 model years (2016–2018). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communication21TG01 Exprired - Replaced with Campaign 23TA13 During a recent investigation of reported battery fires in 2013-2018 RAV4 vehicles with gasoline engines (excluding hybrid models), Toyota discovered that many non-Toyota retailers and others who sell or install replacement batteries were recommending a small size battery for replacement. Toyota specifies a particular size replacement battery for the RAV4 that does not include this small size. The smaller battery may not fit securely with the RAV4’s battery mounting parts, and, in some cases, can move around when the vehicle is driven, causing a short circuit. Using the wrong size battery, or not installing a replacement battery properly, can cause damage to the battery and the vehicle, and it could cause a vehicle fire.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota 21TG01 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 21TG01 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.
Which vehicles does 21TG01 cover?
The manufacturer filed it against 3 model years: 2018 Toyota RAV4, 2017 Toyota RAV4, 2016 Toyota RAV4. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
