I purchased a 2019 4Runner a few weeks ago and have a question. One thing I've noticed is after I initially start it, shift into drive and reach about 5 mph I hear a quick buzzing noise. It only lasts about a second. I don't think its door lock related. Those seem to lock as soon as I shift into drive. My assumption is it's something brake/ABS related since it's not until I hit 5 mph. I know ABS usually will do some sort of check when you start moving. Does anyone else have this sound? I just want to make sure its not something defective that I need to take to the dealer. I've never had it on any other vehicle before.
