Stay on top of them hhubby! I guess the recall that was mentioned (back in Jan 2010) to me by the dealership doing my engine repair, has never happened. Mine has been running relatively fine since they cleaned out the carbon deposits (after a month in the shop in which all the work was done in the last 7 days due to Nissan Corporate Tech support). Six and one half months later, it goes into EV mode fairly easily and is not running rough. But winter is coming......I would not be surprised if they just clean out the carbon deposits once they get bad enough that the "Service Engine" alert lights up.
#106 of 175 Owner's Manual for Altima Hybrid

Did altima hybrid owners have a special owners manual for the altima hybrid or did you just get a regular altima owner's manual. I was given just a regular Altima owner's manual that does not even mention anything about the hybrd.

No, you're supposed to have the correct manual, the Hybrid, NOT regular Altima manual. How did they get away with that????

Wow! That is really unethical!! The hybrid manual is night and day different from the regular manual. You should report it to Nissan and demand a valid hybrid manual. I'm sure that the pdf is available on the internet.

I have a 2009NAH. A few months after I bought it, intermittently it idled very roughly when the car is cold. During the last few months, I noticed that EV was not always coming on. This week, the "Service Engine Soon" light came on. When I called the dealers service, they asked me to bring the car back asap. Diagnostics showed that the cylinders in the engine were misfiring. They said this was due to carbon build-up because the springs in the cylinder valves are too strong and this caused the valves not to close (or maybe open?) completely. They replaced all the cylinders with ones that are now re-engineered with weaker springs - apparently, Nissan is aware of this carbon build-up problem. The service mgr told me that mine is the 3rd car they had to make the repairs. After the repairs, the car runs muchmore smoothly and quieter; it used to have this high pitch whine when switching to EV. Now the whine is gone. As annoyed as I was with the problem, I was really pleased with the customer service at the dealership. They were very efficient and seemed to know of this problem. They did the repairs in 1 day and gave me a loaner car without any hassle. Car is under warranty so there were no charges. Friendly service too. Let's hope I don't have to go back again.
#110 of 175 Carbon Buildup/Cylinder Misfire
Dec 06, 2010 (7:11 am)
I just starting having the issues that many of you are having. On start-up, after about 30 seconds of smooth running, the engine would start to rattle and make a really horrible clanking/grinding noise. The hybrid system does not come on nearly as much as it should anymore. The check engine light comes on for a day or 2, then goes away, but comes back within a week (issue has been going on for 4 weeks now). Took it to Nissan dealership and they hooked up a diagnostic to it. It showed cylinder 3 was misfiring. After letting them do further tests, they came back and said I would need a "Top End Engine Decarb", for which they want to charge me $372 which is not covered even by my extended 6 year warranty! I told them that this issue seems to be known by Nissan (from reading posts here) and was worried the cylinder head might be damaged from the carbon buildup and paying all that money for a top end decarb and then finding out the part needs to be replaced anyway would not be ideal.
Anyone have advice on how to deal with this? Is it possible to convince the dealership that this should be done under warranty? Is the cost for them to run some chemicals through the engine really $372? I live in Northern NJ, so if anyone knows a dealership that will take care of this in a better way, please let me know!

I can assure you that they are trying to get a way with something. I have had some issues with Nissan being honest, to say the least. I ended up calling my area representative, and then ended up dealing with Nissan corporate. I would suggest going straight to corporate. Did you see the post before yours? I says it all. I am still having issues with mine. they won't even do a diagnostic because they don't hear the rattle when I take it in after it is warmed up. I am going to have to leave it over night and go back early in the morning. Yours should be easier, I hope. good luck!

Thanks for the reply hhubby1. The worst is usually in the morning when it really misfires badly. I actually took a video to show them the issue (or at least let them hear the noise) before I left it overnight. The mechanic didn't look that interested in the video. When I went back after leaving it overnight, the mechanics report said that this is normal hybrid start-up noise. So, either the grinding didn't happen, or "normal start-up" includes horrendous metal on metal type noises. I called a local auto shop that has a "BG" machine and they said the most expensive carbon flush is $250. So, needless to say, even if i can't get this resolved by Nissan, at least I can do it for less than $372 + tax. I will be calling other dealership service centers and Nissan Corporate though since this looks like a known issue even though nobody will admit it.
#113 of 175 not carbon build up in NEW cars
Dec 07, 2010 (6:51 pm)
No, you need to BE there when they stat it to prove what it is doing. They are not going to do anything they don't have to. I have taken mine twice. The first time, told me it is 'normal engine noise' when it was dinging all over the place. I took it again, when it was silent. I said, ""Do you hear anything? "no" I won't put what I said next. But to say the least, my car is going in and they are going to have to fix something. I don't know if it injectors or computer, I don't really care. It's under warranty and they are going to honor it. Period.
