Read the originalRead on October 17, 2026
- What it is
- A Toyota service bulletin, hosted by the US National Highway Traffic Safety Administration, that lists voice command faults on Entune head units in 2014 to 2015 Toyota models and the software update that fixes them.
- How much weight it carries
- Official manufacturer document. It covers specific model years and Entune software versions only, and it describes the car's own voice command system, not dictation into a phone app.
Facts taken from this source
- Toyota's 2019 service bulletin lists, among the faults fixed by its Entune software update, a voice command system that freezes when a voice command is used immediately after the ignition is turned on, on Entune Premium Audio units in 2014 model year Corolla and RAV4 vehicles.
