i have also experienced some technical issues but more minor and seems to happen during heavy rains...

one of the fog lights wouldn't come on... and once in a blue moon the autotailgate won't close when i hit the button...

I think it's just water seeping into certain areas and causing temporary shortages...

but once it dries it alright again...

it's been raining constantly these past few days... and it just happened again today... (30 min later it went back to normal)

not a lemon...just the way these things are wired...
