Lexus nav systems freak out after over-the-air update

Lexus navigation and infotainment glitch from update

Affected Lexus Enform infotainment systems require dealership reset

A significant number of Lexus models from the 2014 through 2016 model years were hit with an outage last week that disabled navigation, climate control and audio systems. Lexus confirmed an over-the-air update to the infotainment system was behind the glitch, which caused the screens to reboot repeatedly without starting up.

The automaker announced that it stopped the broadcast of the faulty update on Tuesday of last week, as reports of infotainment system outages began pouring in.

“Errant data broadcast by our traffic and weather data service provider was not handled as expected by the microcomputer in the vehicle navigation head unit (center display) of 2014-16 Model Year Lexus vehicles,” dealers announced in a statement posted on their websites as well as Facebook.

“In some situations, this issue can cause the head unit to restart repeatedly, affecting operation of the navigation system, audio and climate control features, and the hands-free mobile phone functions. The data suspected to be the source of the error was corrected last night.”

Lexus says that the glitch can be corrected via a system reset at the dealership, which will be performed free of charge, and the automaker encourages owners to bring their vehicles in.

The glitch also appeared to affect 2016 Toyota Land Cruisers, and was confined to several geographic regions of the U.S. including the south. Lexus has not listed the affected models or regions, and has not mentioned whether a subsequent update will be able to cure the issue without a visit to a dealership.
