Z is 4 Days Old Having Problems
 

Got my Z last Sunday and took it this morning to get venture-shield installed (didn't drive it since Sunday). On the way back, I hit bumper to bumper traffic. I have an AT and was pressing the accelerator lightly to keep up with the slow pace of the traffic. Once I let off the accelerator to roll to a stop, the car would start to lunge forward and shake.

I thought maybe this was normal for the car as I haven't driven it in traffic before... However when the traffic opened up I hit the gas and got nothing.... the car started to shake and buck violently...

At this point I pulled over and shut the car off... When I turned it back on it drove fine....

Is this a one time freak occurrence? Anyone have any idea as to what this can be? Almost feels like the transmission is shifting gears insequentially.

Has anyone experienced something similar? I know if I bring it to the dealer I won't be able to recreate the problem... I think I will drive it tomorrow to work to see how things go.

The car literally has 100 miles on it...:mad:

Bad fuel pump? Faulty spark plug? Sounds like a fuel issue. Either way, take it back to the dealer. Could just get worse over time. Does your automatic have the sports package? If not it might have been the traction control. Traction control plus no limited slip equals lurching.

This could be a bad tank of gas as well -- but it could be a whole lot of things. Only the dealer will be able to really tell you.

I have a base model, no sports package. There were no light flashing on the dash or anything.

apparently the ECU tends to go haywire with random cars, its happened to a few people, they just shut the car off for 10 minutes or so, restarted it, never had the problem again.

I think I had this problem once, and only once, turn it off/on and most importantly make sure your gas cap is tight

Thanks guys... I'm gonna drive it again tomorrow and see what happens... I hope it's just a one time thing.

wow that sucks man..hopfully it dont happen no more.

dont wait too long cuz I would take it back and say no deal on the car and get a different one. Note: did you get that stuff installed? If so you may have ruined the possibility of getting a new car.

Yeah it could be a whole mess of things, if it happens again definitely take it in.

:iagree:

Yea I got it installed.... I don't think they would take the car back even if I didn't--probably just send me to service.

I'm gonna play it by ear, hopefully it won't happen again. I'll keep you all updated.

well you do have a certain amount of days that you can return the car if not happy with it. I know my salesman discussed this as I think they have to by law. I wanna say 30 days but Im not sure about that. Check into it even with the installed thing cuz you dont want to be stuck with a lemon, which they should have discussed with you by law too.

And I owuld take it in right away and have them look at it so that you it on record. Protect yourself man.

Yah I had something similar to me happen when I first got the car. I pulled over and restarted the car. I haven't seen it happen ever again and I have 18K on the car right now.

Now what if it started happening again and cuz you never took it in you may not be able to declare it under the lemon law. So what I am saying is it not worth the trip to the dealer to get it on record just in case? The guy in the runaway prius never had his accelerator stick but once too.

Thank god I have a demo car.

every possible first glitches already have been fixed if there were any

:wtf2:

Yeah, I don't think the dealer will put 93 octane on the car, so it could be that.

Your car is introducing itself to you by showing you who is Boss. JK, that gotta be the worst right after buying your new car. Keep us posted, hopefully its a one time occurrence.

If it started happening again after 18k miles, I wouldn't call it a lemon. Just a mechanical issue that can STILL be resolved under warranty.

Well for one, I'd need to replicate it in order for the dealership to record it. I couldn't make it happen again, so there was no reason to take it to the dealership.

I had this exact same thing happen not too long ago at about 1500 miles. I have an MT, but your description sounds exactly like what mine did. Stopped in a parking lot, shut the car down, re-started and all was O.K. There were no warning on the display, etc.

I took it to the dealer and described what it was doing. They hooked it up to the computer and found no codes or anything else to help them diagnose the problem. Intermittent problems that don't throw a code will be difficult to find because basically you have to drive it to the dealer while the problem is occurring. I'm not sure I could have gotten it there.

You guys must all be running MAC's and never experienced the Blue Screen of death. A Re-boot usually fixes the glitch..

But since you took it to the dealer its in their system so if it becomes a problem you already have it documented and it can be used if you had to declare a lemon. Thats all Im saying, get it on record just in case.

Its kinda like medical, the more thats documented the better it is later on for disability.

true but what if its more like every couple thousand miles of hundred miles? I get everything looked at at the dealer when I take it in, even if I cant replicate it on the spot, its on the record. Whats that old saying? " an once of......."

I think this is the difference between some companies as to what thier repair problems are compared to other companies. People that own BMWs and Mercedes, etc. tend to take the car in for everything, big or small, and this makes their repair reports look bigger. While other people that own other brands tend to let things slide or fix it themselves and it doesnt get reported on the companies reports so they look like they are doing better than others, when they may not be.

When I go in to get my rims fixed that the dealership messed up when they put on new tires Im also going to have them run down a couple of squeaks that I hear and look at one of my brakes that is making a groove when the others are smooth. Let them deal with the sh!t. But to each his own.

This is true, they absolutely do! You can check any BMW forum and you will see just that!

OK... I drove it to my office, from my office to a meeting and then back to my office with no problems. Driving home from my office is when it started again.

I think it has something to do with the auto transmission.... It almost feels like it is prematurely switching to a higher gear (no power at low speeds) and then switching back to a lower gear (causing the car to buck and shake.) It didn't get to the point of not being able to move this time because I pulled over and restarted it once I felt it happening. Even then it still felt wrong.

There is definitely something wrong.... I'm bringing it in first thing tomorrow for service. Is there a grace period where you can return the car for a full refund? Anyone have any experience with this?

:mad:

Sorry to hear, it's best to take it in now. The lemon law pretty much states that if the problem can not be fixed in a reasonable amount of attempts it can be deemed a lemon. I think a "reasonable" amount is 4 or 5 times in 2 years...something like that.

New York Lemon Law Statutes

You should be able to find everything there. As far as straight up returning the car, I guess it depends on the dealership. I would think most would rather try repairing it and later on declare it as a lemon.

Thanks for the info.

By any means, this should not be happening to a BRAND NEW car!

Just wondering what temps. your seeing (engine temps.) when this happens?

I believe I have the same problem that TheWeatherman had in his FX35 in the first video of this thread:

http://www.the370z.com/nissan-370z-g...-question.html

The only problem is, when I got on the Z hard when it entered this low rev mode it crapped out on me (had to pull over, turn engine off and start it again)
Would a reflash help?

The jerking when coming to a stop seems to be par for the course (I have found other posts in this forum mentioning it).

Took it in for service today, dealer reset all he could.

Also filled what I could with 93 octane... Let's see if this goes away.

Have you changed your gas station? They may have crap in their fuel, bad tanks who knows. Trying a different brand fuel might help, too, you never know. G/L
