Advice from those over 100k miles
 

So the Z is at 99k and I'm having some second thoughts going forward. It's always been properly maintained and outside of a failed CSC 1000 miles ago I've had zero issues since buying it in 2010. I took the opportunity to replace clutch kit and master cylinder while I was at it. The car is bone stock and on the next oil change I will be swapping the gear oil on the differential and replacing spark plugs. Belt still looks good.

I am currently debating on keeping the car for another couple of years or selling it and buying a new 2015 ride with warranty for piece of mind. For those of you who have driven the car from 100k miles onwards please chime in and let me know what issues, if any, you have had. I'd love to keep the car if repair costs can be minimized to maintenance items only. I'd love to hear your thoughts on the Z's reliability.
Thanks in advance.

Would love to hear from others also. Since this is my daily driver would like to see what to expect. I'm already starting to put money away anyways for those just in case things that will happen.

The advice from a family of car dealership owners/salesman is to sell the car now and buy a new one. Unless its a 40th then maybe not but even i have mileage limits. Mine is at 46k now and we will see how I feel around 70k. After 100k unfortunately most values decline dramatically. Depends on how you look at it from an investment standpoint..

I am not ever going to sell mine. I have driven a many a Z to the high mileage range of 160K to 300K. What you should expect is the water pump to go around 120-140K. Next would be alternator, and then the starter. Drivers side window motor some where in the mix maybe. Only one guy on here has that kind of mileage. He has had minimal issues. Look for the mileage thread.


Oops, I left off the CSC replacements. I think the guy at 200k had 3 replaced. By the way, paid for is good.

You can expect a few repairs for sure, but if you take care of the car you really shouldn't have to spend a lot of money on it. Some things are more likely to fail than others. I would just set aside some money for whatever happens so you can fix is asap.

Here is the thread Spooler was referring to: http://www.the370z.com/nissan-370z-g...000-miles.html

Thanks for the thread. Wow, 300k miles.

Thanks Jarblue. That's actually not too bad for over 200k.

As a few guys have mentioned, i'm well over 100k miles. rolled 225k the other day. Since the last CSC about 45-50k miles ago no other problems. Still on original starter, Alt. Hell i'm still on the original battery! LOL Other then the CSC there hasn't been anything other then the regular maintenance time stuff. With my next oil change i'll be doing a oil sample for blackstone, forgot with the last change, but I don't for see any problems there either. As long as you keep up on the normal maintenance you should be good.

Things I would do now if I was planning to keep the car another year...suspension, it's a little sacked out at this point. As well replace the rad...mine has taken a beating, not sure how much air really gets through it now, but that's due to hitting a LOT of bugs. lol

Oh and paint! winter driving in Canada has taken a bit of a toll on the car.

If you have any questions, just pm me.

Curious how your transmissions are holding up aside from CSC issues. Any synchro issues or gear grinds?

No issues from my transmission at all. 2nd gear was getting a little notchy right before the CSC failure. When I swapped out the stock clutch it still had a good 20-30k miles left but I wasn't going to drop the transmission again so I replaced it with the southbend street clutch kit. I replaced the gear oil with some mobile 1 and shifts are as good as day 1.

Mine has been good otherwise...Redline oil change every 60,000 miles.

That's good to hear. You hear a lot of synchro issues on this forum and it's good to know this is a transmission that can last if taken care of.

really? ive not read much about a syncro related issue in a while.

i only remember reading one guy that posted he had a defective syncro going 5th back like 5-6yrs ago..

when reading that people replace their csc multiple times, why not go with the z speed csc?

the highest mileage car i owned was my rsx-s at 104,xxx and it had no problems.

my dad has a 99 toyota rav 4 with 250,000 miles and it's still going. he changed the oil ever 2,500-3,000 miles.

i personally think how much you take care of your car is how much it will take care of you.

yah, if mine ever goes out while i own my 17k mile 09, i would get the one with the external slave cylinder like the one mr.jar haz.
then i could fix it on my own.

or you could just photoshop it in :stirthepot:

My first one didn't go out till I was 150k about...the next one that went out not long after was covered due to the first one. combined with ship times to Canada and I can have my car down while I wait for parts. That being said if I was going to keep this car for ever I would order one and have it ready to go.

see that's crazy. then you have someone whose csc went out at like 15k. it's just mind boggling to me that some will go out so soon and others last a while

lol i did half your mileage in literally 1 year of ownership... then again you have mor toys to play with :mad:

but if i had to chose the replacement... it'd be the chaepest one to source. as both options seem to be viable alternatives.

on another note though... has anyone have a failed HDCSC?

true dat! :rofl2:

the external one you dont need to drop the tranny to do the replacement if it ever failed again. that's a huge delta on labor cost. aka free :icon17:
i think my rc cars are catching up to my Z's milage.. :ugh:

Well my stock one lasted 98k. Not too bad. However I did replace it with Joe's Z speed CSC because of the horror stories on this forum lol.

especially for you, i'd keep the z then. such a waste selling the car after you fixed all the weak links. :)

plus those are highway miles right? probably in WAAAAY better condition than say a granma driven 5min trip car with super low miles. :ugh:

yeah, no point in selling your car now. i'd keep it
old people shouldn't be allowed to drive. they see you and still merge into you. they hear you honking your horn and everything, but thug life.

yeh, i know they want to be out and about like the rest of us, but they should use their retired community shuttle imo too. for their own safety and ours.

another reason why i hate motoring my Z during 'geezer hour' which is weekdays 9:15am to 11:30am..

:rofl2:
haven't heard that word in a while lol

Yeah, it's so random, my next one only lasted 8k. lol damn thing. But it was due to a higher pressure clutch kit.

As far as I know, the HD CSC has only failed when paired with a Spec clutch.

yah, i suppose that could kill it.

Yeah I think 75% is highway miles.

Think only geezer's use it :ugh:

:rofl2:
wait for it

Now THATS the truth LOL
you said "Motoring" LOL

Lol on calling a Z purchase as an investment. Sell unless you've made up your mind about keeping it forever.

the Z is it for me as far as sports cars go so it will be with me for a very long time :)

it is an investment... an investment in pleasure :excited:


RACECAR!

Well if you consider it an investment then all cars by nature are a bad investment. To me all it represents is a car that gets me around as needed and provides what I consider important from a vehicle at an affordable price, ie: looks, acceleration, reliability, handling etc.

90st experience is reassuring. I would love to keep the car for however long it remains reliable. I am hoping that is at least another 50-75k miles. I'll probably reevaluate it in 2 to 3 years when it gets to 150k.

I just hit 100k a few weeks ago and my SES light went on with the code p0011. Hopefully that doesn't happen to you..

97k here. My car has been perfect mechanically and the interior is in like-new condition, just rebuilt the clutch like you, I replaced the shocks and brake rotors at 65k, otherwise stock. I plan to keep my car for 3 more years, then I may keep it as a backup daily driver and buy an R8 or something really fancy.

I know this post was a while back but my csc went out twice before I put exedy stage 2 clutch on it (mistake for daily driver). Bought the car brand new in 2010. At 3k miles the csc went out and again at 11k. Nissan replaced transmission because some of the gears were bent. Replaced clutch around 48k with the exert clutch and light weight fly wheel. Couple weeks later went out again. Replaced it with Z1 csc delete kit and no issues since. Nissan makes a cheap csc. I have over 108 miles now. I was debating on getting a newer Z but wanted to keep the one I bought myself brand new. I just had the steering wheel lock part go out. I'm sitting in Nissan now with my belt that just broke passing the Nissan dealership going to dunkin donuts haha. Made a U turn and pulled into Nissan with no power steering.

What are some preventive maintenance things to do for over a 100k mile Z do this crap doesn't keep breaking?

To prevent CSC from going out you did the right thing. As for the steering wheel lock, pull the fuse in the fuse box under the hood. Wont happen again.

100k Maintence (since im having to do it right now, im at 99,200)
Clutch, Flywheel, Pressure Plate, CSC elim or HD CSC
(Right now im about to install my ACT clutch flywheel and pressure plate. And also am about to install my Z1 csc elim kit.
Rear Diff
Axles (if you ever want to boost or want to make sure they aren't wearing)
Engine- upper/lower manifolds, Rods, Cams, Heads, intake filters.

With enough money you could make this car last for a very very long time.
