Replying to: zerr (Jan 20, 2009 10:33 pm) using an injector-cleaner additive (STP, for example) every 2-3 tanks of gas to avoid this problem. Worth a try!

Replying to: zerr (Dec 12, 2008 12:11 pm) Is this specific to Nissan? I wouldn't think Prius and Camry hybrids would sell so many if hybrid doesn't work. |

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.

Where in VA are you and what dealer are you using? I'm in NOVA. Since our dealers don't see many of these, it's difficult for us to really know what is normal for these and what is definitely a problem. If you are around NOVA, I'd be happy to let you ride in my Altima if you want to see if it feels anything like yours. Unfortunately I'll be pretty busy for the next couple weeks. As far as your issues go: 1, the engine does rev and seems a bit rough when starting cold, but I have never felt mine is misfiring. With the issues some have been having with misfires, I wouldn't be surprised if yours really is. 2, is this issue only when you are getting close to a stop, or even from higher speeds when you first start to brake? Mine brakes seems to be a bit, well, "rough" for lack of a better word right before coming to a complete stop, but I've never felt it was a safety issue as it doesn't affect being able to stop. 3, the only thing I've experienced that this "could" be, is that the car does make a noticeable, well, "roughness" again when going into EV mode sometimes at the higher MPH levels that EV works (35-42), especially close to 42 MPH. I'm not saying this is your issue, but just throwing it out there. I haven't heard anything about an extended warranty on these, with exception of the battery being warrantied through 100K (don't know if that's true). I'd sure love for the warranty to get extended. I really do like the car, but the issue some are having are scary enough to consider moving onto a different car (when gas gets to $4 again and the economy has rebounded a bit so the resale is strong). I generally use Koon's (used to be Brown's in Arlington). They seem decent enough for this area, but I've yet to have an issue since it's been Koon's so I can't say how they'll handle it for sure. I'm 6000 miles and just over 6 months away from being out of warranty.
