: CTS-V Folks don't have to feel so bad about the V's stock Diff anymore

Many have complained about the "poor quality" and "bad design" from GM/Cadillac specifically, and American car manufacturers in general when referencing the differential used in the 04-07 CTS-V and it's ability to grenade after doing several hard launches and/ or inducing wheel hop. "How could they build a 50,000 dollar car with such a weak part. What were they thinking ?" "American car's quality simply sucks compared to the Japanese" etc, etc.

Well folks you don't have to feel so bad about your diff any longer. For straight out of the superior car building quality of the far east has come the top of the line performance car from Nissan motors, the R35 GT-R. Hailed as one of the great production masters of the Ring and producer of 12.* second 1/4 mile times, all for only 75,000 + with it's computer launch control to yank you off the line and propel you down the track or roadway. . . (scratching record sound)

But wait. Now there appears there's a bad design issue going on in the Nissan R35 realm and owners who chose to use the newly designed launch control of the GT-R will end up destroying their transmission , and guess what folks ? Nissan will not cover it under warranty and are telling their owners not to use a feature designed into the car (warned in the owner's manual) or they will end up paying up to 20,000 to replace the transmission. :eek:

http://www.nissangtrclub.com/showthread.php?t=1441

The car records how it's been treated (VDC off - # of times, etc) so no BS'n the dealership/Nissan.

Publicly advertised 0-60 times achieved by using a function designed into the car, but will possibly void the warranty of the destroyed part(s) if used by the owner. Does any of this sound familiar to the CTS-V owners ?


Anyway the whole point of the post is to point out that other manufactures have issues too, even in the best designed, most expensive cars they make. Certainly no excuse for a poor design decision, but GM isn't the only ones with them, and even the Japanese designs can experience them. :)

Wow that's even worse than the V. I mean Cadillac did build a whole under 5 marketing campaign, but Nissan built this advanced launch control system into the car and then said you cant use it. Maybe that's why the car is so cheap! $75k + X number of $20k tranny replacements! That is CRAZY!

I find it interesting some of the parallels occurring.

1. Car is initially advertised performing at a level that could potentially damage it and cause a voided warranty for the damaged part.

2. Despite how it was shown to perform, the response is now "Car is designed for road course performance, not at a drag track."

3. At this point there seems to be some misunderstanding about how/if they'll cover the failed part. Some are doing it and some are not.

Thank goodness the V diff will only set you back 3500.00 :D

I have to admit that I love the GT-R. I am still thinking about picking one up some day. That being said, if I do I can guarantee that I will NEVER use the launch control.

I'm just wondering how SOTP acceleration feels in the GT-R versus a Maggie'd V. A Maggie is a LOT cheaper!

Only about three or four times, from the looks of it. Sort of like the old saying about putting a 400 shot of nitrous on a car.

"It'll do a ten second 1/4 mile. Once." :lol:

Time for the magazines to re-test the GT-R without disabling the VDC or using launch control. 0-60 in 5.1 just doesn't have the same ring to it, eh?

Not surprising at all. Something has to fail when you have a bunch of motor and traction (just like the WRX when it first came out). Knowing how to drive is the real key.

Don't be too sure that GM can't gather enough information from your PCM to tell how you drive your V now. There are enough sensors to gather lots of data on acceleration, cornering, braking, etc that feed your stability control system for them to figure this out. I have a feeling they check this every time I take mine in for warranty work.

Blown diffs is nothing new on high performance cars, especially on modified cars. I owned a Honda S2000 and that car was advertised with a 0-60 time that required a 7500 rpm clutch drop (redline was over 8 k), so diffs where blowing left and right just check the S2000 forums. I also had an Audi TT with the 225 Hp engine that had been modded to 265 hp with an MTM chip, that one also blew the diff on me, even though I rarely dropped the clutch from a start, which BTW is the only manner in that car which to achieve advertised 0-60.
And the differences on those cars in 0-60 without a hard launch is huge, at least the V is so torquey it will still only be a few tenths off because of a lazier start.
As a leftover from the muscle car days I have seen GM 12 bolt diffs and Dana diffs on Chryslers get obliterated from high powered starts.

All these 0-60 and 1/4 mile times put out by both the manufacturers and the rags are really meaningless unless you can do it day in and day out ... NOT just once then don't do it anymore 'cause she'll blow up.

Next time I see some phenomenal 0-60 time in car ad or article, I'm going to be far more likely to challenge it as BS and not representative of it's true capabilities.




(BTW, you said, "blown diffs" and the GT-R's case was a tranny. But, I know what you mean. :highfive:)

I talked to two GT-R drivers this last weekend. First guy owns his and I asked him how he likes the launch control (this was before saying anything about their diff's grenading), he said that he likes his warranty and hasn't used it yet....$70k+ well spent. The second guy writes for the local newspaper in the auto section and gets a new car every couple weeks to do a writeup about. He was very in love with the car since it has a backseat that can be used and a trunk. I was discussing the launch control and the diff problems and he said that he couldn't test it because either the launch control was broken or the factory disabled it. I told him I bet it was disabled so the journalists don't blow the rear while testing. He also told me that he had his first street race in this decade against a GTO and when he let up at 130mph the GTO was only half a car back and the newpaper guy could see the GTO in his peripheral vision. The GTO has had some work, but it wasn't blown. Granted he couldn't use the launch control against him, but the GT-R still has all wheel drive and should have came out of the start a lot more stout than the GTO.

FWIW

Especially if they hurry up and release the 370Z, so people can forget about the GTR for a little bit.
Also, with GM talking about trying to merge with Ford/Chrysler :puke: that doesn't really help American automobile perception.

EDIT: Pretty interesting how the same company that made the Veyron’s tranny made this one….and the first 50 or so Veyron’s transmissions blew up.

Since everyone's drinking their Nissan h8orade heres another story:

My best friend bought an '03 Z the moment they came out (sick burnt orange too) and took meticulous care of it, never modded a thing past a K&N, and rarely even drove it hard for the 110k he put on it, mostly highway commuting miles with the brunt of his agressive driving at highway rolling speeds. The car has been in the shop for a decent amount of warranty work including tranny when his shift fork pivot bolt snapped, a bunch of sensors, electronic speedo(entire instrument cluster replaced for that) and some other misc stuff. Never went too long on an oil change, and right at 110k (coincidentally it started as he was driving to my house to fly out to IL with me to pick up my V) ... drumroll please... rod knocky knocky. D:

How in the hell an N/A motor spins a bearing at 110k unmodded is beyond me unless there's oiling issues with low pressure, squirters, etc. Either way its a beat deal. Lucky for him he found an Infinity dealer willing to "overlook" the odd noise and offer him full trade in price for his car toward an 08 g37s, unlike the 2 Nissan dealers that told him to pound sand and offered him $3k for the car.

If any of those car rags had a shred of decency and commitment to honest reporting, they'd re-test the GT-R with no launch control and VDC left on- fat chance of that happening, though.

The numbers they've been pimping that helped Nissan sell all those cars are unobtainable by anyone who values their warranty, unlike the Z06 and ZR-1 which can not only produce those numbers without breaking, but will also be covered by The General if they do.
