Mine would freeze and also constantly reboot when I would be on any on ramp to get on the freeway. Very bizarre. By accident I found out the cause even after the dealer was clueless. It was the SD Card used for navigation. It was a slightly loose fit in the slot and when I removed it all my problems vanished but then so did my GPS capabilities. I’m going to try wrapping some scotch tape around the SD Card to see if it holds it in place better. But it’s the SD Card causing my issues.
