It just happened yesterday that my Alarm sensor was going crazy. Automatic door closing mechanism seems going "close" position every kilometer, I check and disconnected my alarm . then went home . At the end of the day the battery seems to go weaker, and notice the bright stop light at the rear, All the gear shift selector seems to go from P to L1.
And for all you know the rubber damper at the stoplight switch just crack and go brittle and just fall off. So it seems that this was not a best rubber chemistry Hayundai had,
Went and look for a rubber that would plug to the hole, ( what a crazy design having a hole right in the middle of a stop light switch) And found the dampers at the doors, cut them about 1/4" adjust the switch and behold. My wife will bring it tomorrow to the Hayundai service CEnter. and would mean$$$$, but no. Mcguyver found out the problem. ! (IMG:style_emoticons/default/thumbsup.gif)
So try to check it out guys.
