omar302 that's interesting because I thought about the same thing. With all these sensors on the new vehicles, all it would take is a small glitch in the system to cause confusion and chaos. This could easily trigger false alarms and warnings. The fact that I could shut of the vehicle and re start it, would set everything back to normal tells me there is no major issue. Two common denominators, it was light rain, and I was using the adaptive cruise control when it happened. I haven't taken it back to the dealer yet, and I drove it the other day around town with no issues.
Interesting when you go on YouTube and see all the videos of new technology vehicles (pretty much all brands) experiencing electrical glitches.
The downside is when you take it back to the dealer, they tell you that they could not find an issue, and everything is fine.
