2019 here; I love it… but… FSD beta I use everyday, but it is still not feature complete with what was promised “within a year” The bottom of the car is literal cardboard, held on by plastic versions of rivnuts. They come out really easy and then the bottom is scraping in the ground. I had to get it replaced after driving through a shallow puddle (<1”) in the rain on the highway which splashed into the undercarriage. It happened a second time back in 2022 and it has since been ‘fixed’ by putting duct tape around the edges and over the plastic bolts. This is a known defect which Tesla corrected on newer models. My control arm bearing failed at 4-years. As I was sitting at the dealership waiting for it to be failed, two other cars drove past making the same exact noise. Looking it up online it is another known early failure. All that said, I’ve still spent less on it than maintenance in any other car. The frustration is just being told stupid shit like ‘don’t drive through puddles’.
