Customers need to go to the dealer to fix the problem
Lexus customers lost the ability to use their luxury vehicles’ infotainment system after an update to the navigation’s traffic and weather info broke the technology. The issue forces the unit to continually reset and makes the whole thing inoperable, including the radio, climate control, and backup camera According to the automaker’s statement on Twitter, the problem affects 2014-2016 Lexus models and the 2016 Toyota Land Cruiser (above). Drivers need to have the dealer reset the system to fix the problem.
Toyota claims an “errant data broadcast by out traffic and weather data service was not handled as expected by the microcomputer in the vehicle navigation head unit.” At this time, the company doesn't know how many vehicles have this bad code. Motor1 spoke to Toyota spokesperson Cindy Knight and she simply said the problem was "widespread" without having more specific details. She promised the company would release more information about this issue later.
According to Automotive News citing Bloomberg, Toyota already stopped sending out the data that damaged the infotainment systems on Tuesday night. By that time some vehicles already received the bad code, though. For vehicles that have it, the only fix is wiping the information through a reset.
