when the car misfires, how long does it do it for? can you replicate it? If you could, I'd take a video of it happening. Good luck!

It last for about 5 seconds. The check engine light will flash for about 5-10 sec then went off. The check engine light won't stay on. This is an intermintten misfiring. According to the service manager, if the engine light flashes, the computer should have recorded the misfiring. It recorded the first misfiring but not the other 3 times. Just wondering if there's a glitch in the computer system. I know that my wife and I are not seeing things. Well, I've left the car to the dealer to try to duplicate the problem for the next 2 days. They told me that they will let their master mechanics work on the car. . Thank you.

I see, if they refuse to do anything, try and get them to change the ECU at the very least, but I hope they find what's wrong.

They won't do anything to it unless they know what's wrong with it. I've called Nissan twice and left two messages. No return calls from Nissan for about a week. I am going to contact the local consumer lemon law attorney tomorrow.

Have a 2009 NAH and dealership service manager advised that they have been seeing problems with IEC engine misfiring due to carbon buildup. He adivised
using an injector-cleaner additive (STP, for example) every 2-3 tanks of gas to avoid this problem.
 
Worth a try!

shouldn't have to do things like that to keep your car running smoothly

I would ask to see the service bulletin from Nissan recommending this. Otherwise it sounds like use of one of the old fashioned ways car mechanics have to separate customers from their money for no good reason.

Wow, this whole thread is scary. I thought I'd look at hybrids because they've been out long enough and should have the bugs worked out of them. Should I just consider a Prius if I want a hybrid or just wait another 5 years for things to get better?
 
Is this specific to Nissan? I wouldn't think Prius and Camry hybrids would sell so many if hybrid doesn't work.

3 Issues with 07 by yaunches

Hi, new to the forum. Hate the fact that I have to resort to a forum to resolve issues with something that Nissan should take care of. Anyway, 2007 hybrid, 45K. Issue 1: When cold, the engine seems to misfire for about 5 sec, rattles the car, sounds awful, but it usually only does it once and then goes away until the next time I start it up cold.
Issue 2: Again when cold, (and possibly damp or wet), the brakes really stutter the car the 1st few times I brake, but again, go away.
Issue 3: When decelerating from 40 or 50 MPH, the car stutters (no brakes applied, just foot off the gas). I read somewhere the Nissan has extended the CVT warranty to 10yr/120K on the transmission. Could this be a transmission issue?
Other than that, car runs pretty well, I average 36mpg in combined driving. Only other issue I see is that sometimes the engine continues to run while I am stopped even if the batteries are fully charged. Not sure if that is because I have heater/AC/radio, etc running. If I have the time, I just shut down and restart and it goes back to EV mode.
Lastly, does anyone know if they have updates for the software used to control the hybrid system? Would be great if they would post at least that updates are available and to go to the dealer to have the update installed. Also provide a list of fixes just like a software company.
 
Thanks and any advice would be appreciated. FYI, I live in VA so the local Nissan dealers are not equipped to do much more than standard engine maintainence.
