yup, me too
 
So the dealer informed me that the intermittent (but more and more regular) whining noise I hear from my 2007 Pathfinder with 62,500 miles is the result of, you guessed it, the timing chain tensioner. That will be $2000 please. Really? Nice quality work Nissan. What a piece of crap. No choice but to fix it now however the car will be sold in about 50K more miles (if it lasts that long).

Just just spent 3 hrs on club frontier forum, an older poll showed 25% of owners having this issue. And I'm sure that result is low, I doubt that poll is a true reflection because some people will just take it up the *ss quielty from the dealers and Nissan.

I would love to see a current poll of all vq35 and vq40 engine owners to to see what the failure rate is and at what mileage, re-occurence...

Nissan may not feel it now, but that is because we are stuck with what we have, unless we are willing to take a great loss to trade it in on another make.

Wait 4,5, 6.. years from now. They just lost 25% + of returning new car sales.

Unless Nissan does a quick 180 and takes care of this issue, I will never consider buying their products again. It's a real shame that my 2006 path, will cost more to repair in 5 years , than my 97' maxima in 12 years that I have owned it.

My advice, tell all friends, family and co workers, if you have one of these vehicles, get it fixed before the warranty runs out. That may buy you another 60k....

Quote from Nissan Literature in 2006
"Like others in the VQ series, the 4.0-liter version includes such advanced design features as Electronic Throttle Control with secondary mapping in 4LO (4x4 models), Continuous Valve Timing Control (C-VTC), Nissan variable Induction Control System (NICS), silent timing chain, microfinished camshaft and crankshaft surfaces, molybdenum-coated pistons, resin intake manifold, digital knock control system, high capacity muffler, lightweight aluminum block and platinum-tipped spark plugs."

Silent timing chain???? Really False advertising???

Maybe they should have tested the engine further than the rub-n-tug on the corner

I'm sure there are many more people without issues that did not participate in the pole, where as every truck with the timing chain issues voted.

andrewdavid 03-13-2011 04:36 PM

I see your point.
But also during the poll, some owners who first stated they didn't have the issue, later posted that it had happened to them at a later date.

mdawg4x4 03-13-2011 05:38 PM

That is true too. In time, many that said they didn't will.

Timing Chain, Tensioner and Guides
 
I just had my secondary chains and tensioner shoes replaced. I have a 2008 Pathfinder. All covered by warranty. Did not pay a thing. It took a couple of days.

What mileage is on the truck?
How did the dealer explain why the shoes wore out?

All this makes me feel REAL optimistic about my Xterra. I've got 105k on it, it's an 06...well outside warranty range. I didn't think much of that annoying noise at first, since it had been making it for so long. Thought it was just a normal VQ40 sound. But, as it's gotten louder, (I can hear it quite distinctly over my K&N intake and Flowmaster muffler) and learning how much it's costing everyone else to get it fixed...I thinking about just letting the bank have my rig! I'm paying $500 a month on the loan as it is, and only making $10 an hour! With gas going the way it is and the prices of everything else skyrocketing, an unexpected repair bill is the LAST thing I need when I'm barely making the payments for my X as it is.

Thanks Nissan, for designing as a piece of Scheisse "silent" timing chain! Maybe keeping it a belt like the 1st gen Xterra would have been better!

mark5s 04-28-2011 04:55 PM

fixed, maybe
 
So I fussed with my Nissan dealer (Tischer Nissan in MD) about why Nissan builds timing chain tensioners to fail at relatively low mileage for a timing chain (my 2007 Pathfinder has 63,182 miles). Botton line was on 22 March they replaced the secondary chains, tensioners and chain guide for basically free (the bill to me was $282.00t I asked then to put on a new serpentine belt when the put everything back together). Not sure how long this will last - will probably sell at 100k miles. Looking at the bill, all the charges for labor and parts are inthe "warranty" column.

mark5s, awesome news. Some dealerships do care about their customers. Even if you did have to argue a little. All the ones I deal with are nothing extra.

callahan98 04-18-2012 12:55 PM

Well lets see, my warranty expires 960 miles ago and now I have the same timming chain guide issue. I called the dealership and the guy was rude ans acted like $1300 was nothing and when did I want to make an appointment to get it done. I am not very happy about this and I live everything else about my truck, but now I have to fix it on my own dime. anyone know how to fix this any pics or instructions. Its a 2007 Frontier 4x4 4.0.
Thanks Tim

Go to another dealer and call the 1-800-number in the back of your owners manual.

mark5s 04-21-2012 03:56 PM

The local dealer was not able to help me which was understandable but unacceptable. They suggested I call Nissan Consumer Affairs (1-800-647-7261) to begin a dialogue. The conversations with consumer affairs were very professional. I made my case, sent them the bill for the repair, and they eventually wrote me a check. I still think Nissan should 'man-up' and begin a maintenance program (aka recall) and fix this problem.

Martyf250 04-26-2012 07:21 AM

I just dropped mine off at dealer this morning to have the timing chain shoes done. $1200 bucks. I made my case with Nissan corporate but only got $250 debit card for my troubles. Anything less than full compensation is not enough if you ask me. I'll probably send them a copy of my bill once it's done to make a statement.

Hey guys I posted on this site a couple years back and I was just curious if Nissan had changed their tune about this timing chain problem, or updated the design at all, but it looks like they are still telling people to pound sand just like they told me. I had an 05 Pathfinder and I had plenty of issues, here are some things to be aware of...timing chain tensioners ($1700 at dealer), front roof rack covers flying off (I think this design was updated in 2006), fuel gauge sender, Variable Air Intake System (VIAS) butterfly valve assembly rattling at 2200RPM (fixed myself), rear suspension camber bolts seized so no alignment could be performed, had to get both lower control arms replaced (quoted $1500 at dealer, had another shop fix for $1200), basically all the heat shields had to be clamped on or bent away from the exhaust to stop the rattleing, bypassed the radiator tranny cooler because I was scared of the intermixing issues with faulty radiators I read about, EVAP canister plugged with dust (quoted $600 at dealer), tires always cupped and chopped from day one no matter if you rotated every 5k miles..the last straw for me was when it started knocking it in cold weather when I'd start it up..in my mind it had something to do with all the metal filings from the timing chain mixing into the oil that then circulated throughout the engine. All I know is that I was embarrased to drive out of the neighborhood until it was warm. Nissan's excuse for the timing chain and the knocking was that I must never change my oil, little did they know that just because I didn't bring it to them I ran full synthetic Mobil 1 and changed the oil every 3000-3500 miles from about 15k miles up until I had that issue, maybe thats why PLASTIC shoes that rub on a METAL chain lasted a little longer than some others...I don't know. Anyway, just wanted to toss my .02 in and say I feel your pain and to be aware of some of the things I had to deal with.
