hearing a hiss while driving
Hello all,
I started noticing a slight hiss a few weeks ago. It seems to get louder the faster I go whether accelerating or coasting. I couldn't pinpoint exactly where it is coming from, but doesn't seem like it's coming from the engine. If I open the armrest and put my ear to it, it seems to be coming from below. You think this could be an exhaust leak? It's happening more often now but sometimes it doesn't hiss. I am taking it to my mechanic soon but wondering if anyone might have an idea.
Thanks

Exhaust leaks don't typically make a hissing sound. They usually tick.
Are the air bladders on the seats working? One might have sprung a leak and you're hearing that or the pump running.
The locks are working fine?
