Something is wrong in my driver door, i know it. The trunk latch hasnt been working properly, probably loose. It takes 1-20 tries before the switch actually unlocks the hatch, maybe dirt or rust on the lock hinge? (Every click it makes a noise, but doesnt open). And as of last night, i think the same problem happened to my driver door lock. I don't have keyloess entry so i manually unlock my car every time, and lock as well. Well, after work last night i went to lock my car and there was suddenly a LOT of resistance. I tried the key in both directions a couple times and added wd40 inside the lock mechanism and there was no change. It seems to function properly when i SLAM the door; so possibly there's a sag in my door hinger thats making the lock not line up when the door is closed? I just want to know if these are common problems, electrical issues are killing me on this car... i also have the supid airbag light on for no reason and part of the backlights behind the a/c controls are out half the time. Hyuindai can build an engine block but not a simple circuit?
