Toyota filed this with NHTSA as a service bulletin dated Aug 21, 2023, received Oct 16, 2023, about the visibility/wiper. It names 135 model years (2016–2024). 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 owners reported

Source: NHTSA complaint database

Owners of the 129 model years this bulletin names have filed 14,418 complaints with NHTSA since 2015. 209 of them name Visibility/Wiper — 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 2016 Toyota Prius, the 35 owners who gave an odometer reading for Visibility/Wiper reported it at a median of 17,800 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

The contact owns a 2022 Toyota Rav4 Prime. The contact stated that while driving 30 MPH, there was a popping sound coming from the vehicle and the sunroof simultaneously exploded, causing shattered glass to fall onto the closed shade cover. The contact continued driving. The dealer was notified of the failure by phone but denied helping.

The contact owns a 2016 Toyota Avalon. The contact stated that while driving approximately 70 MPH, the sunroof glass shattered. The contact stated that there was no glass inside the vehicle because the sunroof shade was in the closed position. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure.

Hi, My Prius Prime recently just suffered the loss of heat in the middle of winter. Based on the diagnostic of my local Toyota dealer, it appears one of the metal heater coolant hose had rusted off. This is not just causing a safety issue of having no issue, it is also a risk as the engine can now overheat and suffer permanent damage.

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 579.5

Is Toyota TSB005823 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 TSB005823 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 TSB005823 cover?

The manufacturer filed it against 135 model years: 2023 Toyota 4Runner, 2022 Toyota 4Runner, 2021 Toyota 4Runner, 2020 Toyota 4Runner, 2019 Toyota 4Runner, 2018 Toyota 4Runner and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
