A couple of issues on my new to me 2008 GT.
1) Yesterday my cruise control was being a little wonky. It cut off when I went over a hard bump. Later it wouldn't stay on. After coming to a complete stop it was working again. I am thinking maybe the brake pedal activated cutoff?
2) I get a jingle/rattle coming from the right rear when I go over rough surfaces. I am going to remove the tire and check the brake calipers. Also, the exhaust. Any other ideas?

 

The rattle was something with the spare tire or jack. Easy fix. The cruise I think its the cuttoff switch on the brake, but its working again so ignoring for now!
