I bought an Infiniti G35x like 2 months ago and I've been having alot of problems since the purchase. I drive really passively and I have actually never brought it above 4.5k RPM yet and the car is only at 50k KMs, so around 27-29k miles. So far, some belt is squealing, most likely the alternator belt, my brake pads started squealing today on the first day of snow. And my front headlight burned out.. All these problems came when the weather got cold (around 1degree C, so its not really cold). The previous owners were around 70 years old so I don't think they did anything crazy.. Any suggestions on what the problems might be?

EDIT: The year of my Infiniti is 2007.

 

50,000 km is about when the brakes will need replacing on a G that has not been driven hard. That's when my 07G35x rear pads started getting low.

There is a serpentine engine drive belt which should be replaced at 48,000km according to the schedule. It may need replacing or tension adjustment. https://g35driver.com/forums/v36-diy...bably-g37.html

If your headlight projector is out, there are guys that can replace that for you, you can pick up a used headlight (e.g. check ebay) or you can pay a dealership a fortune for a new one.

 

Yep, the dealer quoted me 350 dollars for the bulb inside the headlight. I'm thinking of replacing everything in a car shop, not at the dealer since the dealer is gonna charge me probably easily over 1000 dollars for everything.

 

Don't pay $350 for a bulb, buy a bulb from online and pay a local shop to do it.

You can find the Bulb for about $35

Might just be time to replace some parts. This really isn't common, I've got an 07 G35 with 60k (I think? haha) and haven't had any problems at all.

 

It remains to be seen if the bulb is out or the ballast. I personally feel ballasts tend to go before HID bulbs. Either way, you should consider doing the work yourself. Changing the bulbs is easy. Changing a ballast is a lot more difficult because you have to remove the bumper. You can get good quality HID bulbs for $40-120/pair. Used ballasts can be had for cheap on ebay.
