I just bought an 04 G35 sedan 3 days ago and I love the car! Everything works perfect and the car drives great, but when I got home with it and the weather got cooler, I went to start the car and it cranked but there was a high-pitched squeaking noise as it cranked. I am so upset! I am a young female who just wanted a nice car and now I'm afraid I'll have to fix several things that I wasn't expecting to. Does anybody have any suggestions or know which direction I should go?

 

Could be belts? Does it squeal any other time?

 

^+1, probably just belts. Head over to infinitihelp.com and look at the DIY belt change video to learn how to tighten it, it take it a mechanic.

 

+2, belts need adjusting

 

Definitely sounds like belts. Don't worry--minor fix....

 

The car only squeals when it's cranked and no other time. I'll try adjusting the belts. Thanks for the information!
