Vibration/Knocking noise from the rear at 20 to 30 mph?

Asked by May 23, 2017 at 12:18 PM about the 2012 Cadillac SRX Luxury AWD

Question type: Maintenance & Repair

I have a 2012 SRX. When accelerating from a stop there is a noise that sounds
like it is coming from the rear. Amost like a vibration knocking noise, then it
goes away. No check engine light and my mechanic doesn't see anything.
Anyone have any thoughts.
SUV has 55,000 miles on it and has been regular oil changes etc.

Perhaps check to see if the lug nuts are tight. Always check the easy stuff first.

I have a 2012 Cadillac SRX as well and I think I am experiencing the same thing. It has been going on for about 3 weeks now. A "clank" sound that sounds like it's coming from the undercarriage area when I reverse or initially accelerate. It has 55,600 miles on it and has also had on time regular oil changes. Any thoughts?
