Read by machine from the document NHTSA serves (7 pages), read Sep 30, 2026. A part number is shown only where it matches Toyota’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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 18 model years this bulletin names have filed 5,646 complaints with NHTSA since 2015. 996 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.
On the 2018 Toyota Camry, the 68 owners who gave an odometer reading for Engine reported it at a median of 20,600 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Excessive oil consumption - new vehicle newly purchased 2019 Toyota Avalon xle (6 cyl) has excessive oil consumption. Required addition of 2 quarts of oil at 2,000 miles. No leaks evident under car. At 3,100 "low oil" light came on, but could not check because dealer taped dipstick to prevent me from checking. Dealer tearing apart engine
2019 Toyota Avalon · Engine · filed with NHTSA Aug 23, 2019 · ODI 11246041
Engine coolant smell after driving. Doesnt matter how long I drove, 10 minutes or 6 hours, smell is there. Smell is sronger from driver side. Dealership told me it just does that! That they let sit in the parking lot running for an hour and there was no leak. It only has 10k miles on it. It shouldn't reek of hot coolant at all!
2020 Toyota Camry · Engine · filed with NHTSA Sep 19, 2020 · ODI 11359920
I rented a 2019 Toyota Camry for 9 days. Many times while accelerating the engine lost power. It was especially dangerous when attempting turns in front of ongoing traffic. The car would start to go then just seem to die as I was making the turn. Then engine lights would come on and it would just start coasting.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Toyota 24TE04 a recall?
No. A warranty extension 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 24TE04 repair free?
A warranty extension 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 24TE04 cover?
The manufacturer filed it against 19 model years: 2021 Toyota Avalon, 2020 Toyota Avalon, 2019 Toyota Avalon, 2021 Toyota Camry, 2020 Toyota Camry, 2019 Toyota Camry and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
