As far as maintenance goes, I spray the valves with Drislide every couple months to keep the hinge mechanism lubricated, as per TSB 16-NA-003.
Yeah I'll pull it up again but that tsb stops at 2019. And while I hate going to the dealer service, I feel it's something they should fix.


I'll put up that tsb as well for maintenance, I wasn't aware of that so thank you for that.
