Maybe you're less picky, or maybe my car has a bad rotor. The right front they just cleaned up a tad, but the left front had to be turned TWICE before it was true. This time around, I'm going to ask for a replacement. It's only been 7K miles since the last time this was an issue.

They properly bedded them at the dealership when I had them re-do them. Took the car out, used an IR gun to measure temps, bedded them with a similar procedure as the GT-R brakes, although obviously not the same as it's not a GT_R. THat's what I was told. When I got the car, it felt great. Stopped awesome, and I could look at the rotors and tell the brakes had been bedded, or at least something had occurred, as there was definite pad transfer, etc. Smelled like it, too. GT-R tech did the work.

Either way, it's not dust, it's a warped rotor. If it were just dust, it wouldn't have taken a ton of metal being removed to fix the left front rotor, and just a quick clean-up for the sake of it on the right.
____
I tried re-bedding them the first time, 6 hard stops from 60, 4 from 80, drove around on the freeway until the rotors cooled off, never came to a complete stop. It only exacerbated the problem. This time? It's going straight to the dealership for a new left-front rotor.

trust me im pretty picky about the way my cars drive, matter of fact my little honda civic that i use as a daily driver is having the same problems with the rotors that your Z has, but since it's a beater car it's not really a top priority as long as the brakes work properly. On my Z though if that happened that would definitely annoy me enough to get them changed out, but that never happened with my Z even after pushing it pretty hard through the corners and using the brakes extensively. The main thing i always kept in mind though after heating up the rotors that much though was to let them go through a cool down period before i touched the brakes again.

You need to do way better than that, a couple stops from 80 is nothing. Also when you resurface rotor, you are essentially removing metal from it and making them less effective.

These aren't track pads. These are not track rotors. That is plenty sufficient to have cleaned up anything, if it WAS to be cleaned up, doing the above. Anyway, it's a moot point, **** should not have to be done on 10K mile old brakes when they did fine previously, and then again at 17K miles after they did fine after being fixed at 10K. I could understand if they were not right from the get-go, but this is a problem and it needs fixing, and re-bedding the brakes isn't the way, IMO, given what was found last time (one rotor needed turning twice as much as the other).

Anyway, you're right, which is why I want them to replace the LEFT FRONT ROTOR.

If it were just deposits, both rotors up front would have had a problem, they didn't, just the left front. Right front just took a light clean-up, left front had to be turned twice for it to be true.

I'm going to get the rest of my car (TPMS sensor, rear bumper) fixed at the body shop today, and deal with the brakes tomorrow. I doubt they will argue about replacing the rotor, considering it did the same thing at 10K miles and they said it was so bad off it needed to be turned twice, I think an argument for factory defect can be made, in the case of that rotor. Why isn't the right rotor messed up? Yeah...

Why is this an issue for me? It feels like crap turning into a corner when the weight shifts to the left-front. To me, that's an issue. Will it make the car handle worse/less safe? Nah, but screw that. Even my old 5.0 from 1988 had less shudder when I got on the brakes, I don't feel like I am getting what I paid for, and I doubt Nissan will argue.

I couldn't stress this pkg enough...

You and C&D are the only two with brake issues.

Well, the dealership DID argue, my response was to just leave (I was holding up the driver who was with the body shop who was to take me back to my house while they worked on the car, I've been up for about 14 hours, and the service-writer and I seemed to have some chemistry that would get ugly, you know when you meet a guy in some sort of confrontation and you just KNOW it could escalate? Yeah. I didn't want that as an ego pissing match just isn't going to fix my car.). I then called the service manager, and told him the story roughly as follows:

Background: At 10K miles and change, the steering-wheel was shaking rather badly under braking from highway speeds. It was determined that the left-front rotor needed to be turned---TWICE, and the right front, once/cleaned up. The pads, I was told, did not show exceptional wear. Now, at 17K miles and change, the problem is back, albeit not quite as severe. In that 17K miles it has seen zero track time and only one set of tires up until about 50 miles ago. The Service department initially said what amounted to "Sorry, you drive it hard and that's what happens." to which I responded "On a 370Z with the Sport package, driving it on the street will warp the rotors twice in less than 20K miles, having not even but gone through one set of tires!?" Kindof got a shrug-like response from that. I explained that my 1995 Trans Am, 2001 Trans Am, and 2011 Z06 had NEVER had an issue like this, save once at 75K miles on the 2001 Trans Am, and then never again until I sold it 70K miles later. Another "Sorry".

Well, it wasn't good enough, so after getting home I called the Service Manager, and it seems that they are going to figure out why this is happening and take care of the issue, and are curious themselves.

As to those packages? No. I'm not going to spend $600+time or labor to install that. This car is a car, it's not my life, but I want it to work LIKE IT SHOULD. That means Nissan needs to handle up on their stuff and fix it. It seems like they are going to do that for me.

You're getting shrug responses cuz you're comparing a old azz single piston brake system and a $70k brake system from a Z 06 to a Z. I would be shrugging too if you were making other car comparisons in a nissan dealership. You're goal should have been to fix the issue. not make unrelated, pointless and senseless comparisons to a Z.

At least they will fix it for you. You may not have had that issue in those cars but GM has had their own series of BS issues and warranty repair is a bych with them...

GM has been far better to deal with than Nissan. The did a ton of work gratis on my ws.6. GM has been NOTHING BUT AWESOME for the two cars I owned from them. I mean, they have kept that WS.6 overnight diagnosing fuel-pressure issues, tore the steering column apart to figure out why I was getting a security lock-out on ignition, replaced catalytic converter (at 110K miles), and I bought the car used when it was 6 years old from a non-GM dealer. Oh, yeah, all that cost me $0.00. Yeah. GM is on my good side, on the customer-service aspect. Oh, they sold me an LS6 clutch assembly for $375, too, back in 2010, I believe. T/O bearing went out at around 80K miles and I needed to replace. GM FTW! in the customer service dept. But yes, the WS.6 itself was a POS...99 problems, but bitchrotors weren't one, baby!
It's not my fault the 370Z Sport rotors can't take daily driving.

Update: They are turning the rotors. Next time this happens I will just replace both front rotors and consider it "normal wear". At 30K miles, I won't have problems with this, it's just at 10K and then again at 17K miles...wtf!? If I can get 200% more life from my tires and brake pads than my brake-rotors, that's just jacked up. That would be the equivalent of warping your rotors twice every track day that you go through tires, if you tracked this POS. Seriously, nice car, but screw Nissan, I'm going to have to stick with American from now on, the mechanical insufficiency of the car becomes more and more clear to me the longer I own it. It's far nice and better than my G20, but those Asians and I, we just don't think the same. Every time I see how something is put together on the car I want to pull my hair out, it's all backwards, and the results seem to suck except in the interior, which they really got right other than the poor panel isolation that causes a million and one squeaks.

Give me a car that I can take to work and home 3-4 days out of the week that won't warp its rotors. Then we can talk. Seriously. Cannot believe more people don't have issues, as I really don't beat on my stuff. (OEM tires lasting 17K miles should be sufficient evidence of that).


Jesus. I need to just sell this thing, but it does look sexy and until it breaks again it performs plenty well for what I want. Total love/hate. I think the next car will be a 2015 style mustang GT. Great engine, and allegedly they are fixing the suspension. Or maybe a CPO C7 corvette (did the "first time buyer hit" on GM, not again, lol!). Spring Mountain has people beat the crap out of even the base Grand Sport 'vettes for 12K miles on the track and I didn't once set foot in one there that had warped rotors. This is in literal 100*+ Vegas summer heat. There is NO EXCUSE for how my car is breaking. NONE.

I drive it spiritedly to work and home? You know what, there are exactly 5 corners that I can take at a speed of 50mph or greater on the 13 mile drive to work (I rarely drive it elsewhere). There are only 2 places that I decelerate from about 65 to a stop, only one of which is within 2-3 miles of one of the corners. It can't take that? Well screw that, then. It's a piece of **** and that's all there is to it. You find some other excuse for this bitchcar. I'm done making excuses for its flaws. It has great lines, amazing interior, awesome engine (IMO), and decent handling for its breed, but the brakes warping every 7-10K, and the power-steering pump whining like an 80's monte carlo, I just cannot excuse the brakes, and the PS pump is annoying.

Either way, the base package seems like it might be a better car. Maybe the little bitty calipers won't be so mean to the weak little rotors on the base car and it can wheeze its way to work and back without ******** the bed.

Seriously irritated with the fact that you guys somehow think this is normal. I just don't BELONG in the ninny crowd that thinks my drive to work is "hard on the car" to this point. Hard would be tail of the dragon every Sunday on R-compound tires. Not my 5 turns, 2 stops from above 65, and 13 miles.

You are just special. Most people can't drive as hard as you can.

Looking back at this, I'm really hating this car about 50% of the time. Meh. Live and learn, no more imports, here.

Apparently. Either that or they don't know what proper brakes feel like because they never drove a rental Kia and so they think that shaking is normal when they apply the brakes, lol. That's how I noticed it this time around, coming from driving a Kia Optima for a month, I immediately noticed how shitty my brakes felt, front end and wheel shaking noticeably. I think it had "crept up" on me while I dailied the Z and I didn't notice it until yesterday having not driven it in a month.

PS. I drove the Optima the same way I drove my Z, although I was about 5mph slower on the corners (I pushed it more than my Z, I guess, in the scheme of things. I stay far from what I think the limits are in my Z, taking corners at about 0.4-0.6g, based on what I used to see on my G-meter in the Z06 at the same speed on the same corners). In about 2000 miles, I did not manage to harm the Kia Optima in any way, except for a small carbon smudge on a seat where I set my suppressed M4. I cleaned it off though before turning it in. :tiphat:

Honestly you should of just kept your z06, going to a 370z is a huge downgrade

Good to hear that there may be an end to the whining in sight.

Yeah, none of us know what we are doing, only you and maybe bigfoot knows.

I just know that my car is dicked up and keeps getting dicked up and I'm barely driving it, so to speak. Glad you got "a good one". I prefer **** that works out of the box and doesn't need dinky little upgrade kits to not take a dump on me. That's what I THOUGHT I was getting, at least for street use. Total disappointment in this car from a mechanical standpoint, but I do enjoy the look of it and it is a blast to drive when it works.

Pretty much, I should have just spent the money to upgrade the interior. It was a mechanically sound car and wouldn't have kept breaking like this thing does. However, I would now be in jail instead of bitching about my cheap import on some forum, because had some stupid welfare thug lost control of their SUV and hit my Z06, I think I might have beat their ***, woman or not, we would have had a "busdriver" moment.

Not for a while, sadly. This reminds me of my time on LS1tech.com when I bought a WS.6 because everyone said they were so great, and everything (except the brakes!) kept breaking, and I bitched about that POS until the day I traded it for a Sentra and felt like I got a good deal (and still do!). I'm going to just keep this car until the monthly repairs exceed the note on a new car made in 'Murica.

That said...GM handled their customer service far better than Nissan, although Nissan is turning my rotors, the left front for the 3rd time. How many times CAN you turn rotors on a Z car?

All that said, I am sure I will get it back and love the sexy lines (they did hit a home run, there) and the new PSS tires and all that, and sing its praises again for a month or two until the next thing on it breaks. Then we will do this song and dance again. Meh.

Well used, but no shaking. Oh wait, maybe I just don't know what shaking is.

Or maybe your car isn't a piece of ****. Look, I can't help that I bought a piece of ****. I did not know Nissan had this many issues with their Z car and shoddy quality and components. My bad. Now I do, a day and $40K too late. I know my Sentra used cheap metal, cheap glass, and cheap components, but I thought that maybe something had changed in a decade. Apparently Jap cars still use the softest metals, thinnest most brittle glass, etc. They are beautiful, but they just can't compare to Detroit Iron when it comes to handling daily use, I have found. Even the paint is weak. Bah.

My car isn't great either, but I know 14" rotor don't warp that easily.

Well why then did they need to turn them down so bad, and why are they telling me it's "normal" to warp the rotors if you hit a puddle or some such ********?

I don't know what's going on, I just know that they turned my rotors last time and that fixed the issue for 7K miles, and when they turned them, they took twice as much off of the left-front because they said even after turning it once, they still hadn't gotten a clean surface on it and needed to turn it again.

If that's not the definition of warped, then what is?

I don't know the definition of what's going on other than: Pathetic product.

Sorry all, but if you spent $40K on a new car and every 10K miles needed to turn the rotors "because it's normal for them to warp", had broken 1 windshield 3 days after buying it because even the slightest pebble destroys the cheap glass Nissan uses, and had a power-steering pump that growled like this (this is only about 1/2 as loud as it can get sometimes, it is worse after taking corners. This is just sitting in a parking lot. It gets me weird looks sometimes. Yes, Nissan looked at it, went over everything, told me their tech-line says "it's the nature of the car". Really? I doubt that very much...):

and was told all this **** was normal...maybe you would be pissed to, or maybe you are just used to crap out of Japan and don't know what it's like to own a car that isn't made of ******* tissue paper. I have, and I do, and this car sucks in the "holds up" department. Everywhere else, I love it, but seriously? It's fail.

Oh, look, somehow I'm not the only one. Who would have ever ******* imagined? :bowrofl:

Most of the issues are well documented. You just have to be willing to listen, though you never know which ones you'll get.

Because resurfacing a rotor is cheaper than replacing pads and rotors! Also do you trust every BS the dealership feed you? They once told me my trailer hitch was the reason why my TPMS lit up and why I have fuel starvation. As someone else noted, the quiet pads Nissan put on the car makes it easy to leave deposits behind.

Maybe it's me, I see more steering lock failures than rotor replacement/resurface threads.

Sorry we are not responsible for your bad luck.

Also judging by the resale value of Japanese vehicles and American vehicles, I would say most don't agree with you that American cars hold up better.

Probably has something to do with the fact that America can produce tens of thousands of mustangs a year and Japan can only crap out 5,000 370's or so. You will also note that the current mustang gt's are more reliable cars than the current 370Z according to every survey you can find. I'm finding that to be the case, myself. None of my friends with 5.0 GT's have had issues, and some of them are quite spirited with the cars.

No, you're not responsible, but I'm not going to jerk the car off like the rest of you just because I drive one. I'll call it for what it is--shoddy engineering with a pretty wrapper.

I am not sure what the 5.0 or Circle jerkers have anything to do with your brakes? If you just want to argue and complain, just say so.

lol, wow this turned ugly real quick...you wanna talk american reliability....1st nice car my parents had an early 90's lincoln continental they bought brand new off the lot fully loaded with all the bells and whistles, 2nd week they had it they had electrical issues with it took it into the shop and it literally caught on fire while in the shop...second vehicle my parents bought a 95 or 96 dodge RAM when they first redesigned it, went in multiple times because the brakes kept failing on it and had to be bought back by dodge under lemon law, third car my parents bought was a plymouth and i forget the model cause not even a month after they had it they pulled over to the side of the road because it was overheating and it also caught on fire, fifth car a brand new 98 mercury mystique with the v6, lasted quite a while until the transmission decided it didnt want to work anymore and one little knick in the paint on the roof turned into a huge rust spot, 6th car my parents owned a 2004 dodge stratus transmission started leaking all on its own...so tell me where is the reliability of american made cars in all this? face it dude all cars have problems whether they be domestic or imported, you just happened to have gotten a bad one out of the batch and yet you insist on bagging on all imports.

My G20 was a bad one, this 370Z was a bad one, how many bad one's do you think I need to get before I get smart? I think two, being every single import I have owned, should be enough, yeah? I have owned multiple American sports and muscle cars and only one of them was a problem child. The rest were great. Also, that was then, this is now. It's 2013. What happened back in 2004 is ancient history in the auto industry.

Nissan seems to think this is normal, so whether it is or not, that's how the claims will be handled, so if it's not the car taking a dump, it's the service behind it, which is really the same thing, considering that all mechanical items can be flawed as you have noted above.

I think I already stated that I was pissed and wanted to complain and when this was fixed I'd be find for a month or so until my car broke or had an issue again.

Noone has anything to do with my car being a POS but Nissan, but people who stick up for the car and say "You're the problem" and then show me pictures of cracked rotors clearly wouldn't last a day in my car without breaking some fragile something.

lol, oh you want something a little more recent then huh? how about my moms current car, a 2010 chevy malibu which had to be taken in 2 or 3 times cause they refused to believe that her power steering unit was trying to kill her by randomly jerking the steering wheel away from her and the dealership was going to try and charge her for even though the vast majority of the electric power steering units in those cars were under a recall. face it dude i can go round and round with you on this, i will agree that yes there are some great american cars that are really reliable but lumping in all imports as being cheap junk as you seem to imply is fairly closed minded of you on your part. im sorry that you are having problems with your z, but i think it would be more constructive for you to aim all your frustration and anger towards imports and nissan in general at the nissan dealership/nissan corporate

Okay, what Japanese import sports car exists in America in the $30-40K price-range that is in current production?

Subaru is it other than the 370Z, am I wrong? Scoobies just don't appeal to me. Not their fault, but they are Lancer's with tarted up drivelines and I am not going to pay that much for one.

I've now owned two Nissan/Infiniti products and they are well made using cheap materials. That is my opinion of them. Easily cracked windshields. Warping rotors. Rubber that rots under the hood, etc. The construction on them is GREAT! and I love the workmanship, they just need to use better material. The are using crap materials and doing premium work, while American cars have crap workmanship and premium materials. Just my experience and generalization about them.

My car's been towed twice due to fuel stravation and the steering lock, I also had a gas tank replaced at 10K miles. I would be the first to say the car is not bulletproof and I hate Nissan Corp as much as you as getting warranty work with them is a nightmare. At the same time, you are calling the car fragile because you have a vibration from your brakes and got into an accident? If you want attention, just post as a girl and you will get the same thing.

MX-5 Miata had a pretty good run, they did what 23 years? Their VIN starts with a J....

Actually I think the car held up DAMN WELL! in the accident I was in, and am proud of how well it was engineered. My issue is with the quality of the material used regarding "hard parts" like brake rotors, windshields, body panels, etc.

It reeks of "cheap" but the price-tag doesn't reflect it. There are all kinds of steels that can be used for things, I refuse to believe that Nissan is using a quality alloy for a brake rotor. I realize it is cast iron, but it warps like pot metal.

Miata is a damn solid car, but it's not in the same league as the Z, although I have considered one. The doors...oh god...those doors...those doors are the reason you see cops on TV using car-doors as cover from rifle fire.

Subaru's are very much the same in terms of crap material and quality construction anyways.

I remember thinking that the Lancer's when I saw them in parking lots. They didn't seem to wear well. Go look at a C5 corvette or a 2005 Mustang GT that hasn't been run into a pole or something, and unless it's dirty, it typically looks new. The 350Z really isn't that bad in that regard until you look inside and see all the dented plastic. At least, that's what I noticed when I rode in one back in 2010, seems like it was worse interior than my Trans Am, and certainly rattled more. I have no experience with Mitsubishi or Subaru, though.

STi is a $20K car with a tarted up driveline, same as EVO, though, so I don't doubt that they have serious issues since all of the money is in the driveline.

there are lemons and issues with every manufacturer. My oil pressure light started coming on on my 13 Mustang GT when stopped with the car in Drive, We bought a new 97 Camaro Z28 and 4 of the spark plugs fouled out on the 40 mile drive home,, bought a new trialblazer that had an antifreeze leak, had a 350z that had to have the engine and transmission replaced under warranty.

Stuff happens. Just spring for some quality rotors and you should be fine. To me, the money spent on the rotors would be worth a lot less than the time ******* around with the dealership.

If you want it fixed right, do it yourself.

My subaru was fine (and I think most are)...it's more of a sound/feel issue with them.

The WRX runs closer to 25K (usually under), so it gets away with it in my mind...


At the end of the day, it's very expensive to build cars in Japan, and frankly Japan itself is poorly situated for the JIT manufacturing they love.

There's a reason Honda/Nissan/etc are building plants in the US--costs are much lower when you are located close to your supply chain and don't have to ship your product across the ocean. Because of this you'll either see a premium on Japan-built cars (like with the S2000), or you'll see corners cut somewhere.
