There are 4 owner-reported lighting complaints for the 2019 Toyota Highlanderin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
AHB, which is part of Toyota's TSS (total safety system) fails intermittently and because the system is run by a sensor, headlight may or may not be illuminated during periods of darkness. Given the intermittent nature of the failure, it seems like there should be something to indicate to the operator that the lights are either on or not on, but the green light indicator goes on and off without any warning, meaning lights are on or off, operator has no way to remedy the issue at highway speed, causing an extremely dangerous situation.
The headlamp socket is melted. This is the same issue as other Toyota vehicles. There was a recall of the Toyota Tundra for the same problem in 2021.
The interior lights stopped working and the drive side sun visor won’t stay up and the beep never worked when I back up to something to close
