A routine over-the-air software update has caused a glitch in many Lexus infotainment systems.

Reports from owners on Twitter claim that their head units simply stopped working, with videos showing the Enform infotainment system starting up and then continually rebooting, preventing customers from accessing all of its functions.

'Many of our owner’s vehicle head units stopped working,' reads a tweet from Lexus. 'We are working around the clock to find a solution. Stay tuned for more information.'

So far, the only resolution seems to be taking your Lexus into the dealership to have it rebooted. Some customers on Twitter also report that disconnecting the battery will reset the head unit, though this may not be a permanent fix.

Old News - And Not the Whole Story:

FROM LEXUS CORPORATE:

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. In some situations, this issue can cause the head unit restart repeatedly, affecting operation of the navigation system (if equipped), audio and climate control features. The data suspected to be the source of the error was corrected last night.

The correction is a forced reset and clearing of the errant data from the system. Disconnecting the vehicle 12V battery for at least 5 minutes and then re-connecting the battery completes this reset.

Lexus owners experiencing these issues should visit their dealer for a complimentary system reset and a confirmation of the system

Thank you for your patience and on-going support.[/B]
