How are you guys! Proud to be one of the 2010 G37 owners! Just wondering if you guys have experienced the following scenario.

I was getting off a freeway, going at about 60mph in the DS mode, saw the traffic light suddenly turns yellow, so I mildly stepped on the brake and tried to slow down, but my car responded to this was by down shifted to about 3-4krpm (40-50mph but don't know which gear was in), during that time, I heard the tires were screeching and felt that I lost the control of it for about 1-2 seconds.

Also, this is a repeatable experiment as long as I am driving it in the DS mode, nothing like this will happen in the D mode. So I am wondering if this is a known issue or just for my car?

 

it's the downshift rev matching. it's normal. this will be more aggressive in DS mode compare to D mode.

 

its an issue called rev matching.

 

To my knowledge when in the DS mode, the display will only show "DS" and does not show which gear you are in and when....which is a flaw by Infiniti when programming the system in my opinion. That display should track each and every gear you are in at any given time but unfortunately it doesn't. So it doesn't surprise me that you didn't know what gear you were coming from, or going into. What I'm not following you on is that you "heard the tires burning.....and lost control of the vehicle for 1-2 seconds"? Confused....

 

Thanks for the inputs!

So it's normal to have the tires screeching and the car sliding while rev matching?

 

i seriously doubt your car was sliding or your tires were burning? when i am in DS and i hit the brakes as hard as i can the car aggresivly downshifts to engine brake and help pull the car to a quicker stop, as well as put me in the correct gear to go into a corner in. i have actually listened for it and kept track of the gears it goes into and out of and it is exactly what i would do 99% of the time if it were a 5 speed manual.

 

i'm not sure what you mean by tires burning and sliding? were you skidding?

 

It was more like the tires were screeching, and I am not sure if it were skidded, but I felt I lost control of the steering during that time.

 

I think it really comes down to getting to know your car better.

 

I thought it was supposed to be very difficult (but not impossible) to get the wheels to break traction when the VDC is in the "on" mode.

If you are sure the "loss of control" was not due to road surface (sand, oil, etc.) and you truly can repeat the condition at will, I might be concerned about whether the VDC is working correctly.

Can you do a burnout from a standing stop? I can get the wheels to screech a little pulling away from a stop while cornering but they are not actually breaking traction.

I am not claiming to be an expert and it is certainly possible that I am misinformed but... my understanding was that you would have to switch off the VDC to get the wheels to spin (ala burnout).

 

yet another reason to get a manual.

 

^so you can mis shift & grind your trans to death.
it's not a matter of if you will mis shift,but when & how often.
auto ftw.

 

If you can't 'shift' an automatic correctly; a manual is out of the question. When I was first learning to drive a manual I may have had more than a few jack-rabbit starts and ground the gears a few times but nothing since then. It should become second nature when driving. Even my wife felt like the G37 with the paddle shifters was anemic and felt emasculated.

 

If anything, what AnalogWorld experienced was the ABS kicking in briefly while in DS mode. He didn't mention what the roadway conditions were (dry, wet, slanted surface on exit ramp, etc.) but its conceivable his G was responding to rapid steering response as well as the above.

So it's not a "known issue"- more than likely, it's your Infiniti saving your butt!

 

Don't turn this into another auto-manual thread.
