Issues & Defects from factory
 

Hi Guys,

this thread isnt designed to bad mouth the 370Z... i love my car more than my own two arms ...

this is just a thread to see if any other 370z owners have had the same issues i ahave had with mine, and maybe a few others im not aware of ..

- Full gauge not working (last two dots dont light up)
- Boot wont open with out me pulling it whilst pressing the button
- side mirrors make some wierd clicking noise once the car turns on .. (only sometimes)

cheers

For the boot:

The dots on the left (empty) or right (full)?

Mine either...I just went back to the dealer and claimed it under warranty. They orderred the parts in and swapped the springs on the hatch for free. This is common. Read the post mentioned above.

Sounds like the elec motors or the folding gear mechanism is missalligned. Take it in and show em.

Hi GTRFAN.. thanks for your help . the two lights are out when its full .. so to the right .. and the rest i will speak to Nissan about tomorrow .. cheers

Yep all warranty items. The fact that you have three things wrong with it will get you further when you complain. Make sure you only address the Service Manager directly and show him the faults.

I'm always missing 1 light on the right for my fuel.

My hatch was fixed as bulletin authorizing a warranty fix came out mid nov.

I'll agree about the hatch. Haven't had a chance to talk to Nissan about it yet.

My big bitch is the speedo. It's about 8 - 10 % to fast - according to a GPS. I mentioned it to Nissan at the 1000K inspection. They said they drove a Commodore behind it at 70 Kph and it was the same. All that proves is they are both wrong. Does anyone else have problems with the speedo calibration.

I have the boot problem too

and speed o meter i checked with GPS when the car shows 100 actual speed is 92

I do have the "hatch release problem". Now that it's cold, I also have a rattle in the cargo area. Other than that, nada.

I think the allowed speedo error is 10% in the US. So, 8 MPH is within that error range - still kinda' sucks. (I haven't checked mine, so I have no clue there.)

Another way to check your speed is to find a flat road and travel at a constant speed and record the time it takes to go one mile. Perform several runs and average the results.

Sec/Mile MPH
50 72
51 71
52 69
53 68
54 67
55 65
56 64
57 63
58 62
59 61
60 60
61 59
62 58
63 57
64 56
65 55.4
66 54.5
67 54
68 53
69 42

When I'm at 109kmph, I'm actually doing 100kmph.

I'm starting to think Nissan got the tyre specs wrong and the overall rolling diameter is whats causing the innacuracy.

The thing is, if the indicated speed is higher than the actual speed, then the rolling diameter (circumference) is slightly too small (and not rolling the car the distance the speedo thinks it's going).

To fix this we can either get taller side % profiles, but I'm not exactly going to do this as the side wall profile already looks too fat for an 18" rim compared to other cars.

Hopefully Nissan can adjust the speedo calibration at a service? I'll look into this when I get 19" and new tyres in the profile I want.

Just my 2c worth of daily rambling

nope that doesnt fix it.

remember with the 18" and 19" rims - they have the same overall height.

I got 19" rims and ran tyres as per Jap/US spec.

ie front 245/40/19 and rear 275/35/19 as opposed to Aussie front 225/50/18 and rear of 245/45/18.

if you do the calculations - the overall heights of the rims are negligible

my speedo is off too! Nissan will not adjust unless it is 10% out. I raised this issue on the forum this year.

So I do about 10km higher and I am fine - ie keeping up with traffic.

When I say Nissan, I mean globally. So you are right about the 18" and 19" having the same issue, as all factory specs will produce a smaller circumference than what is required for a 100% accurate speed reading. We will either have to calculate a larger TOTAL circumference or get the speedo adjusted.

Then again, maybe this design by Nissan and all manufactures is to make us all reduce our speed? hmm

:iagree: That makes the most sense. I guess they figure that with a car that just wants to go faster and faster, we aren't going to get a ticket as easy.

My speedo is also close to 10% over actual speed, this really annoys me. Having to calculate your actual speed if you are coming up to a speed camera is ridiculous. I don't think it unreasonable to expect my speedo to tell me my correct speed. Apparently in Australia speedos are allowed to read up to 10% high, but they must not read lower than actual speed.
Why they can't get it closer than 10% I don't understand. It is to improve the 0-100 times (actually 0-91) ? Does anyone know how it would be adjusted in Nissan did it ? Is it an electronic adjustment ? Can the Dealer Service do it ?
I am hoping that a new set of 19" rims with different profile tyres will make the speedo read a bit closer to what it should be anyway.
