About a year ago, my lovely (and oh so dangerous today!) wife and I purchased a used Infiniti i30, and for the most part we've loved the car. Compared to the ancient Firebird I was bouncing around in, the Infiniti rides like a limo... It even gets better gas mileage, to boot.
But my wife has noticed (and mentioned) a strange phenomenon with this car, and until now I had written off her complaints as being groundless, because, well, they sounded crazy to me. I know better than to doubt this woman's word on things, but what would you tell someone who insists her car windows are going down by themselves when she's nowhere near the car?
On a couple of occasions she's mentioned to me that she's come out of the karate studio late at night only to find that the car's front windows, both driver's side and passenger, are completely open, despite her insistence (!) that she was certain they were left up and locked. This morning I noticed the windows were open when I carried her karate gi bag to the car before she left for work, but assumed she had lowered the window in order to back into the garage last night. Nope. They had just opened themselves during the night while we slept.
So far this window poltergeist hasn't struck when the car's been parked outside in the rain, but sooner or later it's bound to happen.
So I Googled the problem, and lo and behold, lots of Nissan and Infiniti owners have complained of the same issue. The standard explanation given for most of these incidents seems to involve the handy-dandy key fob, which (to our surprise) has a hidden feature: if you hold down the "door unlock" button for about five seconds, the front windows go down on the car. I assume this has something to do with helping to cool off the car on a hot day, or perhaps to help a locked out owner gain entry to a car if the key fob's door lock mechanism malfunctions.
Most of the responses given on-line suggest that the owner is somehow putting pressure on the key fob unintentionally, which is lowering their windows at inappropriate times. But some of the people posting problems with this issue insist that the key fob CAN'T be the problem, because they either don't use it or it's hung on a peg and couldn't possibly be involved.
So I called a local Infiniti dealership and spoke to a woman in their service department, and she said it could also be caused by a window switch mechanism that has suffered "water intrusion" damage. She recommended bringing it in for a new switch for the driver's side door, since that one controls both doors.
"It's a minor repair and not expensive at all!" she assured me.
So I asked what "not expensive" means in her world, and she said, "Probably less than $350 or so. Simple!"
I don't know what world someone lives in where a $350 charge is "not expensive", but it's not my world.
And it certainly IS expensive when you consider all we ask is that the car's windows stay where we leave them when we're not using the damn car...
