Yep. I did not use straps of the proper strength and it ripped through the back seats (it was in my trunk). I had a '06 Saturn Ion and the rear seats could be folded down to make more space in the trunk. They were in their normal position, but the force of them being hit my the robot must've broken the latches.

Unfortunately with the immense popularity of SUVs in the US, a lot of people no longer have trunks/boots that are isolated from the rest of the cabin.

I was in a 40-mph crash last year with a large old CRT in my SUV. It shot forward from the back and crashed into the dashboard but if the car had rolled, like yours did...who knows
