I don't like a shiny dash so I use distilled or deionized water and a lint-free cloth. If I run into something that water won't take off, I'll spray a very small amount of low-gloss protectant on my cloth, clean the whole dash to prevent color variations, then wipe off as much as I can with a clean cloth.
If someone else is cleaning the car, I tell them not to use ArmorAll-type products at all - "If it's not paint, glass, or chrome, I don't want it shiny."

I've heard a lot of horror stories similar to TexasChuck's - dash gets worse after using a protectant on a less-that-perfect dash. If you want to use protectants, start using them before the dash shows any signs of aging.

Yeah i live in Brunei, but i rarely use the Z. She's kept in the garage all the time and rarely even parked outside. Probably a few times when i was cleaning her but that was it. No abusing was done, i baby'd the car and that's the reason why i'm concerned :( cause i did nothing bad to her

The interior was treated with Diamondbrite's interior detailing stuff in her earlier life, and i wipe them clean with warm towel after every cleaning session.

Dam that sucks. My dash just melts when it sits outside in the Texas heat. No cracking yet!

I don't put anything on my dashes. Just a wet cloth. The supposed protectants will trap heat and the dash gets hotter than with nothing applied.

My car is nearly 6 years and i am also having this problem at the exact same locations on the dash. Unfortunately there doesn't seem to be any solution :shakes head:

So it's confirmed that my Z is not the only one with this problem.. Well the only way to fix this is to refinish the dash :shakes head:

Yeah! This sucks

was this the culprit then? :ugh:

I am not fully sure but it's possible :(

maybe get a material expert comment on the ingredients in their product vs the material nissan uses on their dash?

then sue diamondbright for compensation if they were the reason.

id also check with ur insurance people to see if dat can be covered.

some ford, chevy and dodge trucks split their dashes in about 5 years. :shakes head:

Hi Iwan72, I'm from Brunei and my Z is exhibiting the same problem. Like yours, mine's rarely driven, kept in a garage and when driven, mostly at night. Only 46 thousand kilometers in 4 years.

I would suggest you hound Boustead and insist they fix it under goodwill warranty. I'm doing exactly that and waiting for them to give me a decision. You should not have to fix this out of your own pocket.

What a joke. Cracked dashboard in a car in this day and age is rare regardless of age and brand.

Best of luck to you.

Guys, my 5 years plus old 370z is exhibiting the same cracking at almost the same area on the dash. This suck!

Let me know how are you dealing with it. Is there is oem part replacement for this?

Hi viceroy666,

I know it has been a while since you posted your message. I managed to get the dealer here to replace the entire dash, I had to pay the labor charges which I wasn't too happy with but they did pay for the part. Considering my car is out of warranty, it's not too bad I suppose.

The dash is still ok at the moment but I expect it to crack again in the future unless Nissan has changed the material used to make the part which I doubt.

FWIW, garaged, damp towel only for cleaning and windshield shade when parked outside in the sun... dash is still perfect. I'd be pissed if this happened to me but my guess would be the protectant killed it.
