Reverse off driveway and then hit brakes, get squeal, move forward to stop light, brake, squeal. Then move issues after that. Probably warmed up by then. Very possible oem pads not on it.
I doubt it's still has OEM pads but it might. Mines does it at like the first 2 stops on cold mornings. it does not do it in the warm months. It's a characteristic of the pads I have on my car which ARE ceramic and many reviewers have noticed. If it bothers you switch to a good quality ceramic pad but make sure to read the reviews.
It could be a number of things. Pads or shims could be chattering. Or dust/rust that makes those pads squeal.
My Tundra truck does it too. The previous owner had a brake job done but I plan to replace the front brakes again but do it right this time.
It seems like a fairly easy job but, as is the case with most any job, it does require some close attention to detail to keep the brakes from making noise.
