^that means that the computer in the car registers how high you take the rpms and what speed you do and how many g's your car suffers on an average. If this data is too high or something has changed from factory settings then they can void your warranty

I did not know that.. hypothetically speaking, if someone were to leave their car in second gear and drive around at 7200 RPM's until their engine blew the dealer would not cover you under warranty?

All newer car have some crash data preserved in the ECU that is retreivable. What is preserved varies form one manufacturer to the next. If it has airbags, there is crash data preserved.
GM, Ford, Chrysler: 5 to 8 seconds "pre crash" data is preserved on the Crash Data Recorder (CDR) portion of the ECU (and locked in the case of an airbag deployment) with data including vehicle speed, RPM, throttle position, and braking. Data "post crash" is recorded from .5 to 1.5 seconds. If there is no airbag deployment, the data will be overwritten after 250 cycles of the ingition being engaged or if it is superceded by another crash event with airbag deployment. If there is airbag deployment, the data will not be overwritten. You can buy a diagnostic tool to retrieve the data but if you don't know what you are doing, it is very easy to corrupt the data or erase it (particularly on Ford). The manufacturers or professional accident reconstructionists can retreive it safely.
Big trucks: Catepillar, Cummins, Detroit Deisel, Mercedes Benz, Volvo, and most every other engine manufacturer had much the same capability as passenger car's do with additional detail and it is easier to retrieve.
Imports: All over the map. Much of the same data is available in a crash event, but there is no tool for a consumer to buy to retrieve it. The huge majority of dealerships don't have this capability either. Should you desire the data, you'd have to send the ECU to the manufacturer for retrieval and preservation.
So in answer to what I think your concern is, no Infiniti doesn't have the technologhy to tell if you've been ******* your car out just by downloading ECU data at the dealership.

I dont see where Infiniti, even if had the ability to see it... how could they void the warrenty? When you buy the car you buy the right to drive it how you choose? Seems like a simple concept... but what am I thinkin... Life isnt fair... lol 
That's just not even close to being true. Think about it: If you are abusing something, anything, by using it in a way it's not designed to be used, it's not the manufacturer's fault so why should they pay for your stupidity? If you decided that you wanted to use deisel instead of gasoline, or use 80 w 90 gear oil in the engine, it it their fault that your car fails? No because you aren't using it in the way that it's built to safely and reliably operate. If I drive down the road at 80 MPH in third gear consistently, it will damage the car and it's not the fault of the design or construction of the car, it's because I'm an idiot. Infiniti has to protect themselves agaisnt stupidity by denying stuff like that.

I don't completely disagree, but you should be safe going up to redline as many times as you want. That's why it's there, to protect the engine. That's like saying if you ever play your music at high volume then the speakers aren't warrantied. The max allowed should be a safe range, theoretically. My car is redlined probably 20 times on a 12 minute commute. But I don't camp out at redline in one gear. I just use each gear to its fullest potential when accellerating. That should be hunky dory as far as Infiniti's warranty coverage is concerned. If not, then they need to set the redline lower.

never said cruising at 80 in 3rd...but...If I want to drive my car hard and aggresively... they should fix it if it breaks... if not...why make a car that goes over 70mph then?
Good thing I have a family owned dealership I go to... they will fix anything... Guess Im lucky
