Nissan's CEO is too busy driving around in his Porsche to deal with problems of his own sports car. Check out this newspaper article from today:

can ya blame him? I mean the porsche probably doesnt have the feathering, probably has an operating tranny and also probably doest creak crack and rattle in the cold like the 350z. kind of, "do as i say not as i do", huh. man thats priceless.

We love the car but hate the fact it needs tires every 3000 miles.
Good luck to everyone.

Well, my replaced tires are now showing severe cupping/scaling on the outside edges, I have put on about 6K since the dealership replaced the last set.
The car goes in for the 15K service today, it will be interesting to see what they have to say. I have not run over or hit anything that would have caused the car to go out of alignment.
I too agree with PerAuto. I am not going to give up on my LL case either. My Service Manager says he has heard nothing, but feels Nissan will stand behind the product when they determine what the problem really is. He has been great to work with and seems as frustrated as we are in that he cannot offer a fix.

MUST READ FOR EVERYONE -

39,000 vehicles (350Z's from 2002-03) have this problem

Refer to this linK in autoweek:

http://www.autoweek.com/search/searc...=autoweek&cat_


Nissan is fully aware of the feathering problem. The failed to reimburse me and the dealer I purchased the vehicle from (Ed Napleton of North Palm Beach Nissan) gave me the run around with delays to my questions and unanswered phone calls. Nissan corporation is trying to keep this issue under wraps to avoid bad publicity. My four page letter to Nissan went unanswered. Both the general manager of the dealership and the Ms. Napleton acknowledged in an e-mail to me that the problem exists.

I just got onto this thread yesterday for the first time.

Anyway, I'm contemplating my next move. My thought is to just call my service department and make an appointment to bring the car in. I understand about making a stink with Nissan, but won't Nissan be getting the word anyway from the dealer who does all of this TSB warranty work on my car, especially if the dealer and I determine that my tires are toast and demand new ones. Frankly, it's a little too much hassle for me to be calling some phone jocky to ***** and moan about something that my dealer hasn't even looked at yet.

Also, what about this water on the windows problem? Has anyone had that fixed to their satisfaction?
If like my experience, your dealer will delay and give you the run around. Make your complaints known ASAP

The NIssan dealership refused to put my car on the alignment machine because it was not pulling left or right, so there service tech believes its not an alignment problem, its a "tire problem". I called NIssan customer satisfaction #(1800nisssan1)(some ignorant Judy lady) and I have gotten no were, they refuse to replace my tires because Nissan does not warranty tires, it is done through the tire manufacturer and that my car is within NIssan specifications. I had one of the bridgestone dealers put the car on the alignment machine and gave the #'s to Nissan, according to them they are within specs. I'm tired of this dealership and I guess I'll move to the next one, sounds like Rob your having better luck with the Tulsa dealership I'm about a 2hour drive from there.. sooo I'll be giving them a try. Is there anything I can do from here?? Obviously its the car, NIssan will not stand behind there product wich is down right shameful.
I had the same experience. They have already lost a future customer in me. The issue needs to receive more public attention. Then and only then may Nissan consider the ramifications.

Well, I'm still here and have been watching these threads with great interest and deep thought. Sorry in advance for the length.

First time I went in, dealer didn't swap tires but did the alignment, NNA rep (Steve) caught it and I went back a second time in a couple weeks to get the tire swap done. The way he caught it was that the noise didn't change one iota so he called the dealer and found they didn't have the TSB. Of course this was after I told the dealer there was one... Anyhow the noise went away immediately after the dealer performed the tire swap and then came back within a couple of weeks and now my tires are doing the same thing. So I called NNA again and explained the fix isn't working, that there were many having this problem in the forum and recommended he talk to the engineers or have them read my web site or call me because outside of the tranny problems, this one is major. I asked him what Nissan's official position was and he said to the best of his knowledge alignment was the fix. He understood that I was living proof it wasn't a fix. I told him I didn't want a tire swap because that will just ruin another pair of tires needlessly. I told him what I want is a permanent fix. That was a week or two ago. Since then, I have been very busy at work and keep missing him. I am hoping to talk to him tomorrow. Will post if I make contact.

I do believe Nissan is going to fix it and I hope that what I will hear tomorrow is the truth. I'm tired of dealer antics and Nissan not stepping up to the plate. I applaud everybody's efforts to come together in this group to make this a point and try to figure it out.

Towards that end...The truth to me is there is a design problem and it is not fixed by toe alignment alone. Past that my tires are not cupping, this is also not the generally referred to "feathering", and this is also not scalloping. My problem IS an abnormal wear phenomenon that results in a heel to toe feathering pattern circumferentially around the tire (on the inside tread block in my case), which does not have a pat name. Camber (while not adjustable, differing weights of our cars can change ride camber - occupant/tools/etc) may throw this wear from inside to outside tread block or across all tread blocks but I don't believe camber will solve it either. I believe camber will just change where it happens on the tire or extend the effect over time if camber is such that the forces are distributed evenly across the entire tread contact surface. I may buy a camber adjustment kit and have the camber set with me in it, all my normal stuff and a full tank of gas. But, the websites I have seen and the people I have talked to, attribute this unusual wear to vehicles with excessive castor alignments. A friend of mine recently told me his son had this problem (don't remember the car) and ultimately they had to replace his rims/wheels *and* tires. Now just today I met a guy that has a Civic and since he changed tires, he claims to have the same problems I do only his road noise is worse, only on the rear wheels! The kicker is, he bought Bridgestone Potenza tires! But I have not seen his tires to verify this. It's always interesting to see how many people are quick to, oh yeah I got that T-shirt, so I'm skeptical. It also seems possible to me that shocks and springs and dampening rates could contribute to this as well as braking. It could also be that the effect is accentuated with soft tire compositions.

So ultimately...I STILL DON'T KNOW.

Just when I think we may be on to something...WHAM. This is a really complex issue. All of the other standard wear patterns I can visualize and understand the wear mechanisms. But if you asked a ME to design a system that would do exactly what mine is doing, they are hard pressed. I have some ME coworkers (I'm a EE) and we have looked at the car and discussed it, it is really a head scratcher. But our business isn't suspension and tires. With that said, I believe the engineers at Nissan will figure it out, certainly have more experience and probably already have.

Now others in these threads have said their tires are cupped. If true, then that is springs, shocks, wheel bearings, worn suspension joints and the well known issues and causes that every tire shop and dealer should know and is stated on many websites. But if it really isn't cupping and is like what I have, I still refer to the websites I originally posted. Cupping is wearing of the tire shoulders (edges rounded off and mine are not). Scalloping is dishing out of the tire across the tread and the dishes are circumferentially oriented around the tire but not heel to toe on every tread block. Normal feathering is a heel toe pattern across the tread block, the direction tells whether it is caused by too much toe in or too much toe out, but not heel toe circumferentially around the tire like mine.

I cringed when my dealer told me he thought the tires were cupped (first trip when they did the alignment only). When I showed him on my Z and explained this to him he said...."hmmm your right!" Then I also told him that if he called it cupping that an alignment wouldn't fix it, it would probably have to be defective suspension parts. He got my point.

So, if your tires are cupped (mine aren't) then that may be another problem and might require a different fix. I hesitate to combine my problem with the ride issue (shocks and springs) unless your tires are truly cupped or scalloped. But I don't rule it out. A high frequency natural oscillation in the tire caused by the entire suspension system (rims, tires, springs, shocks, aluminum multi-link suspension) has merit. Maybe not enough to cup but has merit. So I'm wondering now, do we have two tire problems going on or a single combination suspension-tire problem?

Lastly, my NNA contact (Steven) has been really nice and helpful. You have to understand they aren't engineers. In fact, he wishes he could afford a new Z... He has been great and will swap my tires but also listened and understands my concern. I don't want to ruin another set of tires, regardless of who pays for them. I'm more interested in figuring this out and fixing it. Then I'll get a set of tires I really want (they won't be Bridgestone). So thanks to Steve (if you are reading) and keep up the good work. My dealer has been really nice, just not very experienced (*ahem*, *cough*, competent, *sigh*).

With that said, I also deeply believe that Nissan does know what the problem is and has for some time. What they may not know is how to fix it for sure or what the best (cheapest/time/tradeoff) approach is to fix it or they may know and just don't have resources aligned yet.

The ongoing part changes may be an indicator but also may not be. I don't know the Nissan supply system. The changes could be different designs or just different suppliers. And it could be related to the ride problem which may have nothing to do with my tire problem and it could be just a bad batch of tires problem. What would be interesting is to order these parts, replace the tires and try it. That would be a good test. When I talk to NNA (hopefully tomorrow) I'll see what he has to say and ask about doing this test depending on what he says.

I applaud everybody's thoughts and efforts on many different fronts, and from many different perspectives. Diligence and patience will pay off, keep it up!

And even though my Z sounds like my '83 3/4 ton dodge 4-wheel drive pickup, I still drive my Z every day!


Enforcer

P.S. I did not have a pull to one side or the other either before the alignment or after nor before or after the tire swap. I don't race, I'm not on a track, most of my mileage is straight and level but a few fun curves, speed varies from 35, 45 and 70 MPH speed limits, 7 stop lights one way, 21.4mpg and 42 mph average, 40 miles every day rain or sun and no apparent affect on braking or cornering.
You sound quite positive but quite honestly, Nissan has lost all my respect the way they have jerked their customers around. Being polite and being responsive are two different things and both the Nissan customer service people and my dealer were neither nice nor responsive.

not to beat a "dead horse", but this is exactly why we as owners need to take advantage of autoweeks invitation for editorial emails. if you are unaware of what i am talking about, review back maybe a page or 3 on his thread and there was a gentleman who offered the link. people come and go on this thread and i want to make sure that all are aware of this great opportunity to make this issue public. and oh yeah i tried the autoweek link above and it was not working, said something about a code required.

It is irresponsible for Nissan to try to cover up an issue that is affecting many of its patrons. In addition, it is not only costly but in poor customer relations to expect your consumers to purchase new tires every 9-10 thousand miles. The only way large corporations understand that they have imposed an inordinate amount of grief and frustration on their consumers is by taking the issue up in court. In this manner, Nissan would have to admit to their mistake an compensate those injured by it.
I agree and I think this train of thought needs to be explored further. Many people on this site have complained but need to explore other options. I believe an attorney who is willing to take on this case would get the publicity needed to do so on a contingency fee basis. To work with Nissan is obviously getting everyone nowhere.

This is real interesting, because the "before" -.02 L +0.22 R was the setting the dealer performed at ~9k miles. Car has not been kerbed or potholed since, so either they didn't do it right first time, or it has somehow drifted of its own accord.

the one bright note is that I got a new set of front tires out of Nissan, with no argument, even over 1 year and at nearly 18k. Basically all I did was call them up and say "I want new tires" and they said "OK". The dealer put in the warranty claim and they were fitted the next day. I was pretty amazed.

I am fully expecting these ones to be the same in a few k though.
That is amazing seeing how they refused to do anything for me at 15-16 K

My problem is making the first move. After going though all the normal lines of BS - I'm just not ready to take on a whole new level of BS. If I were an Attorney, I'd do it - but I'm just a City Planner....


So are there any Attorney's with a 350z with feathered tires???

There are attorney's you can hire that will only take the case on consignment. That being if you win they get paid, if you lose they don't. I filed LL and my attorney would not be wasting his time if he didn't think he could win. Check the web for attorney's that specialize in LL filings.

Default TIRES REPLACED

I finally had my two front tires replaced today. THey were replaced because of the pulling to the right not feathering. They did confirm last week that I have the feathering problem. My tech said that the feathering was on both sides.
If your tire is suppose to be brand new and you run your hands back and forth over the sides of the tire, are they suppose to be smooth both ways? I'm asking this because I asked him how I could tell if I have feathering, he said that visually you really can't but you should be able to feel it. I ran my hands accross one way and it's smooth, the other way felt like a wash board. I checked my NEW tires and they feel the same way only not as bad, is this right? I guess I'll see tonight if the problem is fixed.

Unhappy New tires are now Bad tires

had Nissan put new tires on my car at 11000 miles. They did this with little fuss. They called my Dealer and told them to give me new tires, they were ordered and I had them in three days.(not sure why some people have backorders). Since then I have driven exactly 2200 miles and guess what, the feathering has returned. Keep in mind that my dealer does send all of the 350z's to a pro tire shop for any tire/suspension work with Hunter equipment. I have called NNA once again and can only pray they will get back to me with a fix. At this time I am looking into the Lemon Law for California.

It is clear that the problem is not the dealers, not the tire pressure and not how cars were shipped, it is a bad design.

I dont know about any of you but everytime I see another 350Z (parked, I am not crazy) I check the tires and I have always found feathering so it is clear that they are all having the problem, it is only a matter of driveing type and time that determins the life of the tire.

I hate to give up the car because when it is driving like it should I am having a blast.

Maybe time to look at a G35.

I would never be able to look at another car that's why I'm prying that they give us a real fix on our problems.
