Clutch issue? In this thread or another?

people feeling the clutch "kick" then pressed all the way in..

I called my service dept. and the tech says he does not need to drive my car at the moment. Nissan does not have a fix for this issue, but he is also trying to do some more research.

To reiterate, I would like to encourge everyone who has this delay/power issue to schedule a drive with a tech so the complaint can be logged. Hopefully Nissan will issue a fix.

Digi: Just get that Turbo you want and problem fixed ;)

That's true, boost building up around 2.5K and beyond pretty much offsets that issue. :driving: How's the oil cooler treating you?

All, I just got a call back from my service department. The lead tech called Nissan Tech-Line, and the reason for "power cutting" is due to oil temperature. Suggestion to remedy this issue? Nissan offers an accessory oil cooler. They also suggest using the magical ester oil to further remedy the issue. I'm not surprised by any of this information, but I am relieved that it is nothing serious like VVEL actuator failure, sensor failure, etc.

There you have it guys, one of our primary suspicions since the beginning was: OIL TEMPERATURE.

i still think they secretly put varying levels of "engine protection" in without telling us. Like small steps in power reduction as oil temps creep past 210-220. its a possibility?!

Yea, 220F is the norm that I see when daily driving in 75F+ ambient (after 30min of freeway and stop-go city traffic). You would think they would start cutting power beyond that. My butt feels a difference in 2nd and 3rd around 200F. But yea, that pretty much explains why I can't light up the tires rolling in 1st when the oil temps are close to 220F.

At 23.5 MPG, you can sorta see what my driving habits are. It's just casual everyday driving. Even in that scenario the ECM is cutting power which can take my by surprise while making a turn or merging and having minor trouble keeping up with traffic (i.e., not as fast as anticipated).

That is still weird though how I dont feel what you are describing, meaning if it is an engine protection sorta mode, I'd have the same experience. I dont doubt you by any stretch of the imagination and I have been very vigilant and aware when Im driving, consciously looking for the problem, but I havent seen it yet.

are you gonna try an oil cooler?

It definately takes a few WOT pulls for the car to really give full power as the ECU adjusts to different driving styles. As the temperature went up, I could feel power going down without a doubt not to mention slower throttle response but I never got hang ups while revving nor the type of power cut you have.

Getting an oil cooler made all the difference for me, keeping the oil temperature down around 180 makes the car feel like an animal with noticeably more aggressive power delivery and throttle response; have you considered getting one?

hypertech.....

I'm not sure I'm buying into that story from the tech whole heartedly. Yes the engine is going to cut back power indirectly by pulling timing as the intake temperatures rise, but not as severely as your car seemed to be experiencing. I mean I can beat on the car at auto-x or at a race track and have never really encountered the problems you are experiencing, and that was with the oil temp hovering between 240 and 260.

You're right. It is a very noticeable problem, and it is pretty bad during the summer. When I give it more gas, the exhaust gets loud, but the car doesn't budge (i.e., feels like accelerating in too high of a gear).

As weird as it sounds for ambient temps averaging upper 60s to lower 70s this time of year for daily driving, I may get one. Either way, I'll be getting one once I pull the trigger on the F.I. project early next year. I've been a bit hesitant to go F.I. because of these issues. Based on your experience, if the oil cooler keeps me under 200F in daily driving conditions and resolves these power cut issues I'll be happy!

That's the weird thing. Some people get it and some people don't. Have you seen my YouTube video demonstrating the cut in power? It doesn't take hard driving to notice power being cut. However, as others may have jokingly mentioned, simply drive above 3k RPM and it'll be fine.

Well this is not good. I have had the Stillen "race" oil cooler since it came out and I still get this gas delay problem because my oil temp still hits 220 in city driving...yea I drive aggressive. I am soooooo disappointed with Nissan. GTR had issues with tranny/launch control and now the 370Z has more issues than a 20 year old Geo Metro.

-gas pedal delay
-oil over heating
-Ice mode braking issues (this has not happened to me yet)
-ECU whine noise (this has not happened to me or my car is too loud to hear it)
-Rear hatch sticking issue
-windows rolling down on their own
-oil consumption

This is not cool at all.

Yup, same here. And it's usually under 3.5K, correct? Oh, and it's really bad if you're stopped on a serious incline and try to get going.

WOW, how did I get so lucky... I think I have (or had) ALL of these problems (except Ice mode braking? - What's Ice?)
I didn't look into it, but my driver window goes down a little bit randomly. For the longest time, I thought it was me bumping it or something!

Anyway DIGI, thanks for the info. I'll see if my dealer concurs. I'm not going to tell him any of this since I want them to come to their own conclusion.
