This is for anyone who has purchased the Model 3 roof rack...BEWARE! In fact, if you’ve installed it on your car, I would immediately uninstall it and by no means put any load bearing weight on it; especially a cargo carrier. About 300 miles into my 800 mile trip yesterday, my wife and I heard a loud “pop”, followed a few seconds later by another. It sounded like a couple huge rocks had hit the car but there wasn’t much traffic in front of me to ha e kicked anything up. Since it also sounded like it came from the roof area, I immediately suspected the rack. I pulled off the next exit and, sure enough, one of the crossbars was loose. Luckily, I had decided at the last minute not to use my Thule box for this trip. I uninstalled the bars and squeezed them in the back of the car and I’ll have to haul them around my entire week of vacation. I’ve reached out to Tesla in hopes they’ll warn everyone who has purchased this.
