Went over a bump; hazard lights came on and back seat headrests (and roll bar) deployed. Manual says the dealer has to fix; roof is inoperable while roll bar is deployed.
Twice going over speed bumps my hazards came on, my rear head rests came up and the top is inoperable.
Go to you tube to find a video on how to lower the rear headrests.
roll bar and hazard lights came on when I hit a large speed bump. Now they won't go down and the top won't work.
going over speed high speed bump, still need to fix
Not fixed. Has happened multiple times. Costs to have roll bars pushed down
