Got the preverbial massive rock chip on my 3 week old Nox. Now I purposefeully dont get glass insurance because typically, you get a busted windshield and go for a new one. The glass place says " Do you have glass coverage? OK its 500 bucks". Then you get your insurance to pay it and your rates go up. Tell the same glass guy that you are paying for the glass and not the insurance company and the 500 dollar windshield is now 300 bucks. Thats why I dont buy glass coverage. However, as I stated earlier, I get my new Nox and after 3 weeks of owning it I get my first doosie of a rock chip in 15 years. I go to get it repaired immediately and no one can get me in. So I proceed to go to a movie with my wife. I then use onstar remote to start the car and it defaults to defrost the front window and guess what......the crack runs 8" each direction from the epicenter. So I think. Oh well. Bad luck. Probably 3-$400 for a windshiled and I've saved well over that over the years in not buying glass insurance. If I had got the chip repaired when I first tried it would have been 30 bucks. Now that it has run a total of 16" its a hundred bucks to fix and the crack is still fairly visible. But guess what a new windshiled costs for a 2012 without lane departure warning? $700 in Canada!!! Apparently, the windshield changed from 2011 (my last nox was a 2011) to 2012 and increased about $250.00. Yup, 450 bucks for last years windshield vs 700 for this years. Im still ahead for not buying glass insurance over the years so thats not my complaint. This is merely to let you guys know how much this glass is worth and get your chips fixed immediately and don't use remote start or defrost until it is fixed.
