Same thing happened to me this weekend. Im a little over 51k miles and have never had a problem BUT knew it was coming at some point from reading all the problems many owners have had.
Went to put the top down and it went about a quarter of the way then stopped. The motor was still going like it was trying to complete the process. I stopped tried it again, no movement but the motor was going. So I tried closing it. It went a little bit then again stopped. I pressed the "open" button again then the "closed" button and it finally closed completely.
Now Im freaked out it will fail and get stuck so I dont even want to temp fate. No warrant left obviously, BUT I'm considering purchasing an extended warranty through Nissan...Security+Plus Gold Preferred which will cover the car for an additional 36k miles (with exception of wear/tear items).
Its going to cost over $1500 but with everything that seems to go wrong with these cars I figure its a good investment. I certainly do not have or want to pay $7000 to replace an entire top.
My best friend has a 2013 Roadster. Same exact problem. The dealer could not figure out what the issue was and kept her car for over 3 weeks. They finally had to have a Nissan mechanic from corporate fly to Vegas to figure it out. She was out of warranty and it was going to cost her $6500 to fix. She threw an absolute fit to Nissan Customer Care and they covered the cost.
Any thoughts on extended warranty purchase?
