hey
I own a 8th gen sv
everytine i turn the car off a high pitched whining noise comes from the engine bay. It lasted about an hour. Doesn't anyone have a clue what it may be?
thanks

 

It is the sound of your car crying because you turned it off. Get back out there!

Can you tell if it's electronic or mechanical? I don't know but it might help others answer your question.

 

I can't think of what your noise may be, but it is definitely NOT NORMAL. I have owned nothing but Maximas since purchasing my 1985 2nd gen, and have never heard anything like the noise you are describing that lasted more than a few seconds. If it lasted a few seconds, or even twenty or thirty seconds, I probably would not be too concerned. But AN HOUR? Time to have a serious chat with your service manager.

 

I've been told it the electrical power steering module talked to a few ppl on a fb forum and they're all saying the same thing

 

Noise after it is turned off may be voltage bleeding off the electric power steering. I suspect there is a capacitor that may hold certain voltage for a time so a power failure doesnt leave you with no PS. It seems odd this would last for an hour though. My guess is there is a voltage bleed off somewhere there shouldnt be... I bet if you leave the car sit for several days you may come back to a dead battery. Def worth having the dealer look into.
