Toyota filed this with NHTSA as a manufacturer communication dated Nov 17, 2025, received Oct 17, 2022, about the engine — 3 documents under this number: 22TC07 Dealer and 2 more. It names 1 model year (2020). A manufacturer communication 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.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 314 complaints with NHTSA since 2015. 152 of them name Engine, Power Train — 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.
On the 2020 Toyota Corolla, the 12 owners who gave an odometer reading for Power Train reported it at a median of 15,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Between 10 and 20 MPH occasionally, not always, there is a hard shift that doesn't feel normal. It is usually under light acceleration and conditions. Even trying to mimic it under the same exact conditions, sometimes it will simply not do it.. Sometimes it will be a hard thump. Other times it will feel premature.

On more than one occasion I was going between 5-10 miles an hour and the car sputtered and felt like it was going to shut off. I told the dealership when I took the car in for regular service and the told me the computer did not find anything wrong and they could not replicate the problem when driving it.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota 22TC07 a recall?
No. A manufacturer communication 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 22TC07 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. Every Toyota warranty extension on file lists the ones Toyota has filed.
Which vehicles does 22TC07 cover?
The manufacturer filed it against 1 model year: 2020 Toyota Corolla. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
