First time I heard of this theory... IMS

[Boxtaboy]

In the video below, a comment from user 'Stubahn' claims that IMS failures can be attributed to a certain driving technique from owners who upshift a gear/ or mutliple gears to higher gears when the rpms are too low, thus putting undue pressure on the IMS and eventually that this type of bad driving habit causes the IMS to fail. So it's the driver's fault now.
