Hi everyone,

I was driving on the highway at around 80 mph today, and when passing 80, passenger door motor starts clicking several times, door open light showed up on the dash, and reading lights turned on and off, which was quite scary. I pulled over, opened and closed front and back door firmly to be sure. Kept driving, however same thing happened around 80 mph.

Never heard anything like this before... Any ideas?
Btw my driver door lock is defective for long time, it unlocks on second or third attempt most of the time...

It is a 2010 s2...

 

Does it only happen at 80mph or at the same rpm 80mph corresponds to in other gears as well. Maybe alternator voltage regulator is leading to overcharging the system.

 

Check the rubber door plunger where the front and rear doors meet, make sure it isn't getting stuck/damaged/etc.

 

Happens around 80mph only. Drove on bumpy surfaces, at the same rpm, etc. Did not happen if speed is not high. Giving the idea that maybe wind somehow triggers it?

Also, the door open light on the dash shows up when this happens. Not sure if that light turns on when doors are unlocked with remote...Giving me the impression its not only alarm/door lock trigger issue, but the door really opens, even if there is no sign of it because of high speed

 

tell her if shes gonna jump to stop wasting time lol

have you checked the latch where it meets the striker on the rear door? does it move freely? is it over greased not causing it to fully close?

i would replace the drv lock if its messed up, could be causing some issues so why not eliminate it as a problem
