Replying to: zerr (Dec 12, 2008 12:11 pm) 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.

I have never had this problem in my 08 NAH.
#83 of 89 3 Issues with 07 by yaunches Nov 19, 2009 (7:48 am)
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.

Replying to: yaunches (Nov 19, 2009 7:48 am) Yaunches,   I haven't had these problems, although the engine has always seems to run a little rough when cold on mine. 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. Replies to this message: yaunches (Nov 19, 2009 8:25 am) cptcmpost (Nov 19, 2009 8:35 am) langjie (Nov 30, 2009 7:56 am)

Replying to: cptcmpost (Nov 19, 2009 8:13 am) Thanks for the quick response. I live out by Dulles and have used Nissan of Chantilly. They actaully told me that there is not much they can do. I also called the local Toyota dealer to see if the would service the vehicle since the Hybird system is licensed by them. They agreed to do the 60K maintainence on the Hybird system when the time comes but stipulate that if there are any other issues, they most likely won't be able to fix them. As for the warranty extension on the CVT, just google it, you'll see plenty of hits.   Braking shutters generally when I am getting close to stopping (20 mph and below)   The shuttering of the engine is strange, it happens usually between 60 down to 40 BEFORE the EV kicks in.   Thanks for the offer to drive your car, would love to take you up on the offer. However, for me, time is limited as I will be moving out of state (Iowa of all places) the day after Thanksgiving. So my time is being spent between work and getting the house ready to move.

Replying to: yaunches (Nov 19, 2009 8:25 am) Yeah, the timing seems like it won't work. Good luck finding a dealer in IA. I'm originally from a midwest state that borders IA. At least you should find the Toyota dealers there at least as willing to help as the ones here. It seems like customer service is better back in the midwest.   The braking shutter might be the same as mine. Whether or not it's normal, I don't know but mine has done it since new. I've never felt what mine does was a safety issue. I don't know how long you've owned the car, but if not long, you might notice something else in the near future, especially with the rough roads in this area. When you are braking and you hit a pothole or a bump, it can make it so it won't charge the battery while you are braking. When this happens, the feedback on the brake pedal, and the ability to brake are greatly reduced. There isn't anything I've found that fixes this except just letting the system reset itself by coming to a complete stop or it'll eventually reset after a minute or two of normal driving. I'm pretty sure it's a safety shut off on the recharge system as I think priuses and camries do the same thing. Is that right for the plural of prius and camry?
#87 of 89 same issues in NJ by lightshybrid Nov 21, 2009 (8:54 pm)
I have been back to the dealer recently with the same problems. My car resides in a heated garage, in the morning not too bad. Once I leave my office after one or two hours the car bucks while coming to a stop for about 5 minutes til the engine warms up. It was 60 degrees today and still had the same issue. I just had egr service done last week and $400 later I am still having the same problem. Does anyone know of an updated thermostat? It seems the car takes awhile even for the heat to kick in. The car always starts instantly. I've stopped using the auto temp control, seems to put more stress on the engine while warming up. I have an 07 with tech, nav, etc.   Thanx Larry

Replying to: yaunches (Nov 19, 2009 8:25 am) it's just like that for the first 2 items when it's cold. I live in New England and it's always like that on cold mornings...and afternoons...and nights (why do I live in New England?)   the 60 to 40 seems strange...is it always like that, repeatable everytime?

Replying to: yaunches (Nov 19, 2009 7:48 am) Hello, are you still having this issue? I have an 07, 51k with very similar problems. Because it has began to snow, I go out to warm up the car. I'll start it and when out of EV, the engine will run and sounds HORRIBLE. The car rattles (I can feel the front end vibrating). If I do not drive off or shut it off, it almost sound like it will die on me. It kind of also sounds like something is grinding.   Also, not from 40 or 50 like you are experiencing, but about 25 or so to almost a complete stop the car pulsates/vibrates and does the same thing. I originally thought it was a brake issue and everything looked good when they were checked. It too sounds like it may die and everything is vibrating.   Does anyone know what is causing it. Im not sure if it is trying to kick back into EV and having an issue or not, but when the problems are happening, it will not go into EV and is strictly running gas.   Any insight is appreciated. I love this car other than all the issues Im having (not the first issue).
