I have a 2007 SRX V8 with 92000 miles on it. What the problem now is when standing still, it makes this ticking and whirling noise from the steering wheel and I'm not even moving the steering wheel. Not sure what's the problem. Also my front tire pressure goes down a lot. I've already filled the tire pressure to the appropriate psi. But the next day it just went down to 22 psi. This is just my front driver side tire and there's nothing that's on the tire like a screw or anything. But it just went down like that. Any suggestions?
