There is a regular and repetitive ticking noise on my 2017 Model S 100D. I have scoured the forum (strange noises and vibrations are a popular subject), and this noise seems different from all the other noises being discussed. Below is a linked video of the sound:
It is prominent on acceleration and regeneration, and the ticking gets faster with increased the car speed. I assume it’s still there at highway speed, just either very fast or overwhelmed by road noise. The sound comes from the rear of the car and, while soft, can be heard in the cabin when the windows are up.
Attempted (failed) repairs: I have twice taken it to the SC. The first time they “performed molly coat and torqued the axle nuts” and reassured me it wasn’t a drive unit. The sound was gone for like 15 minutes and came back. The second time they replaced the left rear half shaft. The sound was softer, but not gone, and returned within a day. Maybe not quite as loud, but it’s coming back again.
It’s not the wheels or tires, because I tried switching to neutral while regenerating and the sound immediately disappears even though the car is still moving.
Has anyone else experienced this? I assume it is not normal. Thanks!
