When I pulled out of the house this morning and made a right turn out of the driveway I heard what sounded like someone near me with one of those audio systems that have the loud bass beats. Then I realized it’s coming from my vehicle !? Then it quit and I never heard it again ?
Anyone ever hear of this ?

Could some debris or tree branches have been caught under the back of your car or between the wheel arches that made the noise and the fell off as you drove along?
Strange as it sounds, it can happen.

No foreign objects, I stopped and checked. Drove it 130 miles today and nothing, which is a good thing, strange.

Well its happened two more times. Only during right turns at very slow speed, the beginning of the drive and the car is cool. The noise is coming from the right rear so I’m going to check the brake caliper, or could it be a automatic brake adjustment taking place ?

It’s hard to describe the noise but it reminds me of the older vehicles when you apply the brakes while in reverse to adjust the brakes.

Jack up the car, remove the wheel and check the brake pads for wear, and if the caliper is loose on its mounting brackets.
Could also be a worn wheel bearing if it make a growling noise that comes and goes at certain speeds.

I think I have the same thing. I notice it when I leave for work and go around the right hand corner at the end of my street. Weird. Seems that it only does it cold though.

Same here, strange ?
It really is. It's only in the morning, cold, so I didn't really worry about it. And it's not every time. I thought maybe I had something rubbing since I have wide rear tires (325's on 19x11), but I don't know. I thought maybe wheel bearing, but I only have 20k on it? Guess it's possible.

I had a 2012 Nissan Altima, when I would start my drive and the first time accelerating through 30 mph there was a thud sound I found out it was a brake calibration taking place.

Hmm, didn't know that was a thing I guess. Hopefully its just something minor, but I would think it would be common knowledge to everyone by now. Just like all the other weird nuances with these cars ha.

Mine does the same thing. Best guess is it's the clutches slipping and reengaging in the cold differential and you're hearing the splines in the axles take up the slack moving from loaded to unloaded tension on the axle shafts. I've had the brakes and calipers off several times and wire brushed the hub and rotor mating surfaces and checked everything I could think of. 72k miles on the car now and everything seems to be just fine, except I still hear that little annoying noise every now and then. :unsure:

Cactus Jim I’ll take that ! The reason I haven’t taken in right away is it only makes the noise on the first few hundred feet of the drive after it has been sitting for about six hours and sometimes i doesn’t do it.

I’m going to try leaving the driveway with the traction control off in the morning and see what happens ?

When I left this morning I turned off traction control and it still did it but never again on the 45 minute drive.

Its been a couple of weeks since I last reported. About a week ago the noise went away, two days ago it’s back but not as much as before. I wonder if the electronic stability control ?

does the rear differential like to 'warm up'? my car would make same sound every morning after sitting all nite and doing k-turn to leave. i would drive around and try and replicate it and never could after few minutes. finally asked my Father(mechanic) one morning to get in car and he said it's the cold differential, laughed, and said stop worrying.(bc I was making a Federal case out of it for weeks) not saying this is same as you but for anyone who experiences this after car has been sitting and does a turn very, very soon after starting car.

Yep, only when it’s cold and after one mile and it is gone.
