We have the same failure - drove our bot over a defense and it shut off. We thought a loose connection as well, but looked and it was connected. Unplugged, and plugged back in.

No lights. Checked and found 12V on the barrel connector. Checked again - still no lights. We bought this second one from Andymark and put an RMA in. Hopefully this isn't a common issue.

We've wrapped our new radio in foam to protect against shock, but the airflow will be reduced. May have to get creative...
