HotShot Windshield Washer: Just a Little too Hot for Our Tastes

If you happen to own either a Cadillac DTS or Escalade, Buick Lucerne or Enclave, GMC Yukon, Sierra, or Acadia, Chevy Silverado, Avalanche, Tahoe, or Suburban, Hummer H2, or Saturn Outlook with a HotShot windshield washer system, then this post might to be of particular interest to you.
It seems that GM and Microheat (the manufacturer of the HotShot) have been having a mite problem with the nifty system. Short circuits have reportedly caused three engine compartment fires in consumer vehicles so far, plus another 31 other warranty complaints about the units function.
The problem appears to be a relatively easy fix of adding an in-line fuse to the works, which GM will be happy to do free of charge up until November 1st, 2008 (so get down there is you have one of these). There is some 944,000 vehicles involved in the recall, which will cost GM about $20 million dollars of which they are trying to pass the buck onto Microheat, which is already practically waiting in line at the bankruptcy courts.
This fiasco could be the end of the HotShot system and Microheat all together. For those who have never had the pleasure to have used this system, it actually works like a dream (when it isn’t on fire that is). The unit heats up your washer mixture, which in turn makes it a breeze to remove bug guts, tree sap, and especially those thick layers of windshield ice that would normally take up to 10 to 15 minutes of idling just to clear off using a defroster and windshield wipers.
Yeah, we know that you should use an ice scrapper on those cold wintery days, but sometimes we are just to darn lazy to stand out in the freezing cold with a $2 ice scraper glued to one mitten and a piping hot coffee in the other. But if GM is able to pass the buck (er, rather $20 million bucks), this little convenience will be no more, as there is no other company at the moment with a similar gadget on the market…
Don’t go throwing out your $2 scrappers just yet, all you future customers to GM!




A simple LED touchscreen in the dash would never do with a super high tech Shelby Mustang. Instead the new KITT has a windshield 3-D screen that allows information to be passed through the driver while they can also keep their eyes on the road. This technology is currently in the making, so we may see similar designs someday in the future.
