Every morning when back out of garage, 2011 CRV makes a creaking noise from the rear of the vehicle & definately is not brakes. After vehicle is driven noise goes away. Appears rear differentials have had numerous issues & some have fixed by simplying changing rear diff. fluid. Wondering if this is still an issue with 2011's as ours began doing it with under 1,000 miles, hasn't had the rear under water (unless occured when being transported new or at the dealer which I doubt). Have an appt. to have it checked & wondering should I request fluid be changed, have the vehicle run & then changed again? Is there any TSB on this? Thank you!
