Hi all
Greetings from NW subs of Chicago
first post on here
I just noticed something strange on my 2016 QX50 with just under 34k miles on the ODO
When i came from work and was backing up onto driveway i heard strange single "click" sound when i switched from park to reverse. I kept switching between reverse and forward and each time car started to roll i kept hearing that single click sound almost like somebody tapped on exhaust with something metallic. it was definitely coming from the rear.
Im going to call the dealer i purchased the vehicle brand new and make an appointment however before i do that maybe i could get an idea of what the issue could be so i dont end up getting screwed by dealer.
If anybody could chime in i would appreciate it.

They don't call 'em " Stealerships " for nothing . . .

The Service Department is indeed a Profit Center . . .

As for the click sound, the shifter is telling the transmission to transmit power to the drive shaft, then to th rear axel via a differential which in turns transmits power to the wheels ~

There is plenty of moving parts in the above stated process than make a sound as they do their thing

Diagnosing a sound in a worded post on a forum with very little activity most likely won't yield much input

Additionally, the Brake Pedal needs to be engaged for the shifter to move out of park.

Our brake pedals travel a good distance before engaging the brakes compared to other cars ~ are you fully pressing the brake pedal all the way down ?

Sometimes if brake is not pressed firmly, the shifter is giving me feedback that is doesn't want to move into gear

Just adding whatever feedback I can offer, it sounds to me like nothing too serious to be worried about.

My 2017 AWD makes the same noise, It the transfer case area, I'm thinking its something to do with the AWD. Ever AWD I've had Subaru XT and Jeeps all have noisey running gear. It may also be time to blow out your brake pads with some cleaner. They might be sticking. Nothing harmful just heat and normal degradation.

Wondering if you ever tracked your noise down? I was just backing my 2016 into the garage to change the back brakes and heard a similar click. I've never noticed it before. When I pulled the wheel and rear calipers, I noticed the pads were (relatively) loose against the rotor.

This makes me think my click was related to the pads shifting in the caliper. New brakes make no noise ... yet ;)

Try tightening the axle nut in the center of the tire. That worked for me.
