trunk assist failed - Visitor
I have the same problem. Intermittent door lock problem -- now not working at all, trunk soft close no longer works, roof won't go down. Battery drain problems on and off for past year. I think I have a pneumatic leak causing the PSE pump to run and drain battery, and now the PSE pump motor has burned out (fuse reset no longer resets pump). :( Need to find leak, repair and also repair PSE. - papuhl
