I've heard this noise too, first time I thought it was someone throwing a rock at my new ride!

It's always at low speeds, turning into a driveway. A loud pop!

Everything seems fine otherwise, so perhaps it's the brake noise that others have described. I have to think if it was suspension or frame related it would be there in other driving situations.

Going to have it checked it out at my 5k in a couple months.

Funny thing is I can drive into the same driveway and there is no noise. Seems random.

Our suspension is rigid and the tires are a little wider. When you back up slowly while turning, your front tires may catch a small rock and slide off of it. I never had that happened to my older GS but I've observed it happens a lot in the same manner.

I'm not sure if it's the compound of the tires or other factors. Next time, open your window while backing out and turning. Pay attention to the tires. It's likely what I had described... just a small pebble will set it off. (I have a clean driveway too, but there will always be one or two pebbles somewhere).

For me, I realized it's not the brakes, as I mentioned prior.

as far as the sound from the sunroof, I only heard it once and never again.

I will be taking this in in 1-2 weeks to get the suspension looked at or even the brakes. The sound is not coming from the roof panel per the TSB they did repair on.
i am having this same problem... hopefully the roof panel tsb fixes this because its getting pretty annoying

I can duplicate it by going down the drive way and turning left on my street and hear the same noise. It's louder first thing in the morning when going down the driveway after the car is parked overnight. It comes about 3/4 time that I do this same route so its not rare occurrence due to a rock. I can feel it slightly in the floorboards when doing this turn and when that pop/clunk happens. I did the sunroof tsb but still there and occupants in the car would say its from the rear in the trunk area and not inside the cabin.

Wow, this is not very comforting to read when we're about to buy one of these. I'm surprised no one here has asked for their dealership to bring in the factory service rep for proper identification and resolution? Is this affecting early and mid production or late too? Sometimes if you don't request the factory rep to be involved it may take many mos or even years for proper resolution.
Thanks

I experienced this same loud pop/crack sound pulling into a similar steep entry into a parking lot last weekend. I've only heard this happen once, but it's my wife's car so I only drive/ride in it once or twice a week. When it happend, my wife immediately dismissed it as nothing, speculating that it was something we had in the trunk or back seat area. But it's been in the back of my mind ever since. The frustrating part is that it could be happening daily or every other day but I wouldn't know it because the wife doesn't notice it or she dismisses it as something else (not a problem with the car).

Its only ever happened twice to mine, the second time was not nearly as loud as the first time.

There is a repair, a TSB that is referenced here somewhere. It basically involves removing the whole interior, so I'm going to pass.

What production dates are affected in that TSB and the date the TSB was issued?
Thanks

So if the entire interior needs to be removed, does this mean the repair involves the actual structure needs a weld or something to that effect?

Did you read the TSB posted on the first page?

Yeah I did, it's for the sunroof and someone in this thread said they had it done and it had no effect on the problem and many say the noise is from the rear of the car like something was in the trunk, not the roof area.

I got this noise rechecked by my dealer and its not from the sunroof but from the suspension and there is no solution right now... They have contacted the headquarters and will await resolution. Its not as bad as I thought but can be annoying when driving down the driveway and taking a left.

I applied a light brake pedal pressure, to tighting up the pads, while going over the same bumpy road and the rattling goes away. I noticed the rattling after the dealership serviced the front brake for squeaking noise.
