Well this news is decent good news that others have seen the same problem and even mention the exact rpm (3500) that I saw. I just want to see if the there is a common cause for it that might need a recall or at least documented so it can be fixed later under warranty.

Im having the same issue with my 09. It feels like it stalls for a second around 3500 rpm then regains power then does it again in another gear. Went away for a couple months then just came back... I really wish i knew what was wrong with ti so i could fix it..

hey dallas! just like what the other had commented i guess you need to inquire on the dealers itself ...a glitch or a manufacturing defect may cause this..not really sure coz i havent experience it in mine

I am in Chattanooga TN and just went for a coffee run in my 40th. Hit the onramp at 75MPH and my baby handled wonderfully. Tight and straight through the clover leaf.....once I exited the turn to hit the striaght line onto the highway, I had no power. I could only do roughly 40mph and had to pull over, turn her off and back on. Once back on, no issues at all. Does this "limp mode" have to do with some sort of G force during the turn or maybe a loss in oil pressure due to the turn?

Thanks for any assistance.

Check your brake switch. If you have access to an area with no traffic you can test this by pulling the brake light fuse.

^ Wow this is scary. I thought this only happened to 09's? Now it's happening to 10's too? Luckily, nothing for me yet, though I only have 1300 miles on my 2010. So is the consensus that it's just a sw glitch and not really an issue since you just shut off and restart and problem is gone?

So here's a better question.... WHO has had this happen to them AGAIN, besides the first time?!?!?!?!? Because if someone has had it happen to them twice, then there's something definitely wrong.

Limp mode eh?

Toss a couple of these bad boys in your gas tank..might even give you a few extra ponies

In all seriousness though, maybe you could try disconnecting the battery for 10 mins and see if a reset helps it?

Agreed. Nissans are very reliable but they are also very glitchy. There's always these little unexplained problems that come and go that really don't add up to anything in the end. I say do the reset. If it returns push the dealer to check it thoroughly. Even if they don't find anything, cool. Better safe than sorry. At least it will be reported that it was checked for the problem. That way if something goes wrong? You got eem by the balls. Keep all your reciepts.

I had this exact same issue a couple of months ago it was in Jan, I heading home from work going up a mountain range when all of a sudden I noticed that my car lost power and would not go past the 3500RPMs, the only different from mine and the post is that I pulled over and turned off the car it was not hot all temps where good. But when I turned it back on the check engine light came on. I took it to the dealer and they replaced a censor which was faulty.

I had finished a long flight back for work and got to the car around midnight in Texas. Them temperature outside was around 55F when I started the car. I drove about 18 miles in 6th gear at an average of 2650rpm (65mph). I turn off the highway and begin my back roads trip to the house when I'm startled to have no power.

At first I thought it was VDC pulling power but I wasn't even getting on the car, so I tried to accelerate normally and BAM, no power. Looked at the tach and it would hit 3500rpm and not give me anymore. Shifted to 2nd, 3rd, 4th and tested the gears, couldn't get past 3500rpm. Turned off VDC to make sure that wasn't faulting the ECU, still could not get past 3500rpm.

I had read that high oil temps cause limp mode, but I glanced at that temp and it was reading 180. Remember, it was a cold night and I was just trying to get home to get in bed. Now, I'm kinda freaking out because I can't even find a reason WHY it would want to go into limp mode. No warning light, no code, nothing, it was frustrating. Also, I assumed (also read around here) that limp mode was capped at 5500rpm and not 3500. So this also raises my concerns as to why it would do this.

If anyone has information on why or how to possibly find a reason for this, it would be awesome. I hope this isn't a trend the car will continue to have causing major work to fix it.

Thanks

this happened to my co workers friend. She sent it back to the dealership and they could not get it fixed. They did not know what happened. So they gave her a choice. a new z or they paid her back in full. She got her money back. It sucks cuz she has had a z since it came out in the 60's.
