Warranty Voided No More – GT-R Launch Control Now Warranty Safe

Written By Kerry Stratton and Zach Segal

The Nissan GT-R is back in full force – no need to worry about your precious warranty any more. After speculation that Nissan would completely remove the warranty-voiding launch control system from their all-wheel drive twin turbo V6 monster, a recent press release (below) explains that a new reprogramming of the GT-R’s ECU / VDC system will bring the feature back, and make it safer than ever (More info, pictures, videos, & specifications after the jump).

The Problem: Nissan GT-R Transmission / Transaxle Failures

It’s a commonly known fact now, thanks to YouTube (videos below) and enthusiast car forums, that Nissan’s newest implementation of the R35 GT-R has some issues; the biggest being that of its’ launch control system and transaxle failures. Some Nissan GT-R owners, according to Nissan, less than 1% of all GT-R’s sold, who have pushed their new 480 horsepower Japanese supercars to the limits have experienced some…..”technical difficulties” with their transmission. After a set number of launches the car simply decides that it is time for a new transmission, to the tune of $22,415.38 (plus $1,380.00 for labor). Who knows what Nissan’s thought pattern was, perhaps they assumed nobody would read far enough into the owners manual (pictured below) to use the launch control feature.

After many complaints, Nissan has taken the monster back to the drawing board, and is releasing an update to the GT-R’s VDC system. VDC (Vehicle Dynamic Control) is a computerized “babysitter” that keeps the GT-R under control for those owners with heavy feet. There has also been a recall sent to all previously sold cars that will apply the new VDC re-programming to them. Nissan claims the new programming will allow almost identical acceleration with all safety systems still in place. It’s speculated that to save wear and tear on the Nissan GT-R transmission, new system will rev the motor at around 2,000 RPMs – considerably lower than the current 4,500 RPM launch control. Unfortunately if you really want to get a neck-snapping launch out of your GT-R, turning VDC off does potentially void your warranty on the transaxle, although Edmunds InsideLine indicates that the rest of the warranty on the car will still remain intact.

Nissan’s Official Press Release

Nissan has enhanced the Model Year (MY) 2009 GT-R by incorporating new MY 2010 programming that will optimize clutch engagement control for improved drivability. This upgrade also improves vehicle acceleration with the Vehicle Dynamic Control (VDC) ON/activated.

Nissan will provide this MY 2010 specification upgrade to MY 2009 GT-R owners at no additional cost. Nissan has already incorporated this programming into the GT-R vehicles in its U.S. inventory and will resume shipping of those vehicles to dealers. We will advise you soon on how to install this new program into all MY 2009 GT-Rs (see below).

The GT-R will continue to offer supercar characteristics of exceptional handling, maneuvering and overall driving experience. This upgrade provides the consumer improved drivability and enhanced acceleration performance with VDC ON (as required by the warranty). Standing acceleration capability with VDC ON (VDC-R mode) will improve compared to the original model-year 2009 performance while such acceleration with VDC OFF will be moderated. Customers should be reminded to drive safely and obey all traffic laws. [Please note independent media reports of 0-60 drive times with VDC OFF (or what the media call "Launch Control") on closed-courses with professional drivers will likely increase after this change.]

The GT-R Owner’s Manual expressly warns against driving with the VDC OFF (except to free the vehicle when stuck in mud or snow) to avoid damage. Repeated acceleration launches with VDC OFF have resulted in some reported instances of damage to the transaxle. Repairs for damage caused by driving with VDC OFF are expressly excluded under the terms of the Nissan GT-R New Car Limited Warranty… Except when stuck, there is no reason to drive with VDC OFF.

This change was initially implemented with the start of MY 2010 GT-R production and has been completed for all 2009 GT-Rs still in NNA inventory… In a few weeks, you will receive the Technical Service Bulletin explaining how to implement this specification change for all remaining 2009 GT-Rs…
