I received my Model 3 RWD in January, but I have been hanging out on TMC for months. I knew that phantom braking was commonly reported, and I seriously considered canceling my order. I decided not to cancel it because (a) there were no other suitable EVs available at the time and (b) the resale values have been so high that I figured I could probably sell it if I was displeased.
As I anticipated, I have already experienced phantom braking in my first 900 mi. TACC is simply untrustworthy. Perhaps Tesla will improve it in the next update (as is rumored for the next beta).
BTW, CNN just ran a story about Tesla phantom braking. This kind of coverage will chip away at the company's reputation, goodwill, and share price.
Tesla's cruise control woes put damper on 'full self-driving' hopes
Thanks to its computer-centric design, the Model 3 has an abundance of features found on luxury cars. However, the build rides more like a cheap car (maybe a Ford Fusion or Chevy Malibu). Honestly, I would have no problem with the tradeoff (at RWD's price)... assuming everything worked.
My own experience has been a mixed bag. The range and efficiency are really nice. I like the look of the car, the white interior, the instant acceleration, and the cornering.
On the negative side, there have been a few issues. The driver's side of the dash rattles and the audio system doesn't consistently remember what I was listening to. The ride quality seems unrefined (and this is on the more comfortable 18" Aeros). And, of course, phantom braking.
Service? I live near a service center so when my car needed its trunk realigned (due to a giant and growing panel gap), I made an appointment using the Tesla app. That part of the process was great. Unfortunately, when I arrived at the service center, I was not greeted in a particularly friendly way. Arriving at my old Pontiac or VW dealer was a nicer experience. There was no loaner available, on par with other non-luxury dealers. Complicating matters, Tesla.com (and Tesla app messaging) went down late in the afternoon, and I became frustrated as I tried to arrange to pickup my car after hours. There was no alternative way to contact the service center!
