My car went pretty haywire a while back. MCU frozen or taking 30+ seconds to respond to touch, air suspension not working, turn signals not making a sound, odometer showing 0 miles, thermometer not working, all kind of stuff. The car did still drive. I took it to service center a few days before a scheduled appointment. They did a IC reset and everything seemed to come back up.
A couple of days later it all happened again. I took it in for the scheduled annual service and showed the tech everything that was going on. Lots of people looked at it and nobody knew for sure what was going on. There was speculation the MCU would be replaced.
Fast forward a few days and I pick up my car. The invoice shows:
I have no idea what website was loaded in the MCU because I just goofed around with it when there was an update to see if it performed any better (still not usable, IMO) so it isn't like I actively use the MCU browser. It was certainly not one of the active apps on the screen. That said, the issues haven't come back, so maybe there really was something going on with the browser.
Anyone else every here of that sort of thing happening? Seems really odd that a website could cause such extreme issues.

Concern: States that the LTE connectivity intermittently looses connection. Same with bluetooth connection, turn indicators sometimes make no audible noise, slow start up, GPS freezes, suspension not auto raising at saved locations. Last occurrence 6/18/18 at 9-11am. LTE issue happens more often. Touch screen does not respond to inputs 6/22/18 at 1:18pm
Corrections: Firmware General Diagnosis
Technician performed a hard reset. Certain websites can be detrimental to MCU performance.
