Ceiling lining losing adhesion : common issue, not enough material wrapped around the back side. Best option is to get it redone or find another one, won't be able to find the material if you get it redone.

interior roll cage panels falling off: have not seen this one, assume it's the pillars, should just snap onto place.

cigarette lighter stopped working: check glove box light if it's dead as well then fuse under hood.

rear wing stopped functioning (randomly stays up, goes down): usually related to battery issues, test that.

cup holder broke(no tension): cup holder is the worst ever invented, replace with storage bin or find one that has been removed and replace.

right window button fell through console now sitting in the hole 3 inches deep : shift surround lifts right up, pull up snap bitton back into place

Key doesn't turn in ignition unless played with. (Saw that as being common on here a while ago) : sticky ignition key fix thread, fix now while it still turns or get stranded when it locks completely

The air conditioning blower/fan comes on "literally" randomly : mine does this but I have a Black MB controller that is not the right model. Pull radio out, couple screws and check connection in back (wires and plastic arms) when it turns on randomly turn the AC off switch fan dial all the way max then off again. Usually fixes it for a bit and if not wont turn AC on randomly just the fan. Turn AC on when needed.

A few weeks ago we went to go some where and when the car was fired up it felt like 2 pistons where firing. The whole car was shaking violently and sounded like hell. Next day? Normal : no clue

Earlier this week, car would turn over but not fire up. Few hours later? Normal: did it actually try to crank or just "click" could be crank position sensor.
