YES, the QuikrStuff Mach2 bike rack can be used on the popular Tesla Model Y.
Here's what we know about the rack on a Tesla Y:
The rack fits very close to the car. If you insert the rack into the receiver just far enough to cover both expanding pads, you will still be able to get the rack into its upright position. Some Tesla owners report that this isn't possible but that is because they are pushing the rack all the way into the receiver. You only need to push it in far enough to cover the two expanding pads. As long as both pads are covered, the rack will stay secured.
There are also rumors that a loaded bike may bump into the back of the car. This will not happen if you install the rack as suggested in the above paragraph.
You'll need to change the Captive Safety Pin from the left side to the right side of the car. This is because there is an electrical connection in the way on the left side. Moving the Captive Safety Pin is easily done with no tools although it's tight in there and if your hand doesn't fit you may need to use needle nose pliers. The Captive Safety Pin does not need to go through the hole in the receiver; it does, however, need to sit behind the flange on the receiver. Remember, the Captive Safety Pin is not the primary mechanism holding the rack to your vehicle; it is the unique expanding pads in the hitch that do that job.
We haven't noticed the rack interfering with the performance of the mirrors. We aren't big fans of the tilting mirrors (when they tilt way down when you first put it into reverse) and know you can turn that feature off. The car will tell you to STOP when backing up because it thinks the rack is a separate object that you're about to hit. You can turn on trailer mode so it realizes that something is attached.
We know these things because CEO Bryan Wachs has a Tesla Model Y and always has the rack on his car. If you have any further questions, he will be happy to respond to them. Email us at support @quikrstuff.com.
