"Of course, already pointed out in the thread are the http://www.nissanusa.com/pdf/techpub...san-GTR.pdfand http://www.nissanusa.com/pdf/techpub...09_GTR_WIB.pdf. Both explicitly state what is and isn't covered. It's the warranty information booklet that best applies to Septskyline case and explains on page 30, under the "What is not covered" section:
"This warranty does not cover damage, failures or corrosion resulting from... Operating the vehicle with the Vehicle Dynamic Control (VDC off), except when rocking vehicle when stuck in mud or snow..."
To get the word straight from the horse's mouth, we turned to our source at Nissan who summed up the situation: "Switching VDC off doesn't void the warranty nor does running the Launch Control on the car. However, if someone switches off VDC, enables Launch Control and then breaks something while doing this, we wouldn't pay (under warranty) for the specific parts that break during this action."
So for those owners looking to modify your state-of-the-art Japanese supercar right off the dealership lot (or engage in VDC-disabled hooligan activities), be forewarned: Read your owner's manual, avoid a headache, and save yourself what could potentially be a hefty chunk of dough should anything snap, crackle or pop."
