I will be bringing my 07 G35x for an oil change tomorrow, and the dealership stated that I am due for a major maintenance service now (24,000km). They said it would cost around $400 and include brake line check, 'engine shampoo', wheel rotation as well as standard oil and filter.

This sounds to me like it's not really needed - and quite expensive. I am thinking of just asking for the oil change (expensive enough at the dealership).

IF I don't do these major scheduled maintenance and just stick to oil changes will I be voiding my warranty or putting my car at any significant risk for breakdown?

 

"Skipping" the 15k service should be fine. Unless you run your car super hard or something.

I skipped my 15k mile service (I think) since it's pretty much a waste of money. If you really want to get it done, goto a Nissan dealer. Same work for less money.

Cars these days are made to be driven, I think less and less cars are having problems in the early ages. For our cars, I wouldn't really worry about anything until the 50k mile mark upto 100k.

I've had my car since May 31st and I'm gonna be needing the 30k service soon.

 

Thanks, guess I'll be giving that one a miss and save $$$
