Hi
I noticed a noise today.
Starts after 40-45mph and rises as speed rises.
It s like a hissing like air leak but rises as speed.
I dont think it is suspension leak since it rises at speed.
Any coments?
Thanks

Sounds like a vacuum hose popped off.

I just read that cruise control issues are affected by vacuum.
Mine works sluggish ,hesitates sometimes when ac. button pressed.

ac. is aceleration not air con.,

a common problem i had causing hissing at higher speed is the window seal at bottom wearing out.
i swore this noise was from ac or engine
once thet resealed the windshield all was good

I had the same problem at 50 to 70 mph. Took it to dealer thinking it was one of the fans. They issue was the window seal. Quick fix by adding silicone under the front window seal. Tech said this is common in hot weather and that they fix one of those per week.
