Has anyone successfully had warranty work done on an intermittent problem, meaning one that does not consistently show up?

My 2013 Outlander has this weird hiccup; occasionally when I use my turn signal or turn on my fog lights with the left steering column stalk the windshield wipers will swipe once.

I had my dealership look at it twice, but since they couldn't replicate it they were unwilling to take anything apart. I spoke to Mitsubishi NA and they indicate they need a full inspection before they can do anything, a catch 22. If the dealership disassebles the column and finds nothing, i may be held accountable for the labor according to them.

 

dirty rain sensor? just so happen to have a water droplet fall on the sensor?


Not sure how many times this has happened to you
