One of the hoops was dislodged on mine not long after I bought the car.
I struggled to find it at first, but it turned up in the hood stowage compartment!
The dealer insisted on ordering a brand new hoop, under warranty, fitted it and it's been fine since.
And that was 4 years ago.
Apart from a few scuff marks, there was nothing wrong with the original hoop - I still have it in my garage as a spare.
The dealer was quick to point out that nothing else in connection with the roof was covered under AR's joke of a warranty - that shows how much faith they had in the thing.
I was also told that if I'd bought the car from new (I bought at 2 years' old) that the roof was covered under warranty for only the first 6 months of ownership!
Can you actually believe that?
OP - if your only roof problem is with a hoop then be very, very happy.
