another random question.. does the push start button light up for you guys? I've noticed the letters above the actual button wont come on.. example ON, ACC ect.. I'm pretty sure they used to light up at one point depending on what mode the car was in.

 

Mine is still good but then again i did after market for mine like 3 years ago

 

whoops, sorry! I meant Iridium.
I'm only @ 50K and i think i'm already experienceing some rough idle due to worn spark plugs (i take my VQHR past 7Krpm on a daily basis). Iridium or not, i bet they look worse than the ones in the pics.

Read this thread, i'll let the posts speak for themselves. While Iridiums are rated for 100Kmiles, the manual reccomends changing them @ 60K. I'm gonna do mine @ 60K (if i don't sell my car first)

 

I did my plugs myself at 109K miles. I am by no means a mechanic, but am comfortable with tools and following DIY procedures. I was able to do it in about 2 hours as I kept taking breaks and only did 1 plug at a time. The only thing that was a pain was having to take off each TB to reach the back plugs!

My plugs didn't look too bad after 109K miles, but I did notice my gas mileage improve noticeably with the new plugs.

Also, my lights do turn on around my Start button.

 

I'm sorry, I don't know where you're getting your information from, but again, your facts are simply incorrect. The factory service manual clearly states a maintenance interval of 105K for the plugs for either Schedule1 OR Schedule2. It's right there in the FSM (Section MA, page MA-6), see for yourself.

As for that thread, I can't say I'm terribly impressed by it. Did you notice post #8 where someone showed the plugs that went 106K ?? Of course the gaps are going to be off after a full life, but remember, the FSM spec is .043", so a set that went 106K yet was still in a .040 -.055 range is pretty darn good if you ask me.

Again, if you are compelled to change them so early, be my guest, but please don't state misinformation about what the factory recommends and what is routinely proving to be perfectly sufficient (as proven in your own thread link!).

 

Yes it does light up....hmm you might have shorted something out? I don't know.

 

Well... I dropped the car off this morning and they just called with the results. Apparently the push start button was bad, so they are going to replace it under my extended warranty. Everything else checked out, they gave me a loaner for a few days and sent me on my way.

I will post any new info as it comes in. Thanks for all the responses, and I'm sure glad I bought that extended warranty!

 

That sounds good, maybe it was just the button glitching out then (although only when cold??), but it's good they are keeping the car so that they can hopefully do a number of completely-cold starts; just in case there's more that one issue involved.

 

That's funny! Reminds me of the ignition switch that went bad on my old maxima with the same symptoms :P

You'd figure that the lack of an ignition switch would solve that, but I guess having a button isn't any different.

Thanks for keeping us posted!!


VQsmile:

Those are my personal opinions, and i'd personally feel more comfortable changing the plugs earlier and not testing to see how long iridium plugs can last under my particular conditions, since my car falls under the severe service category

 

aka: Schedule1 (according to the FSM)

 

Re-reading the spark plug thread, the OP has said the following:

"had 3 plugs that were very far out of range with the upper electrode worn away. My car has 69,000 very hard miles on it. The decision to change plugs is a result of gas mileage dropping to 19 mpg from 21 mpg. Rough idle and part throttle hesitation"

Based on that, i think i'd want to do mine @ 60K....rather than having them crap out before 100K

 

any update to this? seems like it wouldn't really be the button that caused this, mine does something pretty similar and it drives me nuts

 

that was the OPs problem, you may have a different issue....videos help

 

didn't seem like it was really definitive to me. He said he was dropping it off, but never said that the issue was really resolved. No update on getting it back and having the car actually work because of a button.

I've posted a thread, with some silly replies. Mine sounds a lot like the OP's. Long crank with an unsure first rev or two on an 07 x sedan. Battery is fine, easy stuff is all checked and fine. 68k miles.

 

Sorry for the late response. The vehicle runs fine now with the new push start button, it seems to me that this was the main issue and was resolved.
