got my notice last week and spoke with my local dealer. I was going to do the recall next week after installing my rear roll cage as I was not sure if I would be able to use the top with the rear roll cage. the dealer explained that the problem was not with normal teryx usage, the problem was towing, as faster speeds would literally rip the top off.
Anyway, yesterday I removed my top to install the roll cage, and guess what it is cracked, right along the front at the first bend where there is no support, so now I get to file a claim and hopefully get a replacement.
Also, the top does fit with aftermarket rear roll cages, just need to trim it a bit!!
