It appears that GT-R owners won't have to worry about voiding their warranties if they use Launch Control -- for the 2010 model year, the car won't come with the feature. Inside Line is quoting a Nissan exec as saying "It's gone. We just don't want to deal with the warranty nightmare anymore. It'll make the 2009 GT-R really special. It'll be the only R35 with launch control."
We've previously reported cases where Nissan GT-R owners have brought their cars to the dealership with transmission trouble only to be told their warranties won't cover it. It turns out that disabling the car's VDC (Vehicle Dynamic Control) too often, in order to use the Launch Control function, meant Nissan wasn't covering the repairs. The cost to fix/replace the transmission is only $20,000, so you can imagine owners weren't too upset. Apparently the GT-R owner's manual states that damage to the transmission is not covered if it is proven to be the result of using Launch Control with the VDC turned off. In fact, the manual states that the only reason you should turn off VDC is to "rock" the vehicle when stuck in mud or snow. We await Nissan's revised performance numbers.
