I hear this noise as I am backing into my garage after I have taken it for a short drive. Very annoying sound. If it's in R and I barely let off the brake is when it's at its worst.
Have you noticed this rattle/grinding after driving T4R for 20 - 30 min? That's when I hear my noise. My SUV has 300 miles on it & I know this noise wasn't happening last week. Can someone forward pic of which shield is possibly causing issue?
Undercarriage noise
Do you happen to hear this noise after your T4R has been running for about 15 - 20 min & it sounds like a loose exhaust component or rattle at low rpm or as you let off the brake. If so, I had the same problem. Let me know if this fits your description.
