  Tesla, Inc. (Tesla) is recalling certain 2012-2018 Tesla Model S and 2016-2018 Model X vehicles with a center display equipped with a NVIDIA Tegra 3 processor and an 8GB eMMC NAND flash memory device. When the 8GB eMMC NAND flash memory device for the center display reaches lifetime wear, the eMMC controller will no longer be able to maintain the integrity of the filesystem, causing a failure in some of the center display functions.

  Risk: The eMMC controller wear-out condition can cause the loss of the rearview camera display, defrost/defog control settings, and exterior turn signal lighting, reducing visibility and increasing the risk of a crash.

  Remedy: Owners should ensure their vehicles are operating firmware release 2020.48.48.12 or newer, which will alert owners if the eMMC is approaching lifetime wear. Tesla will notify owners, and will replace the VCM daughterboard with one containing an enhanced eMMC controller, free of charge. The recall began March 29, 2021. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-21-21-001.

   My car is equipped with Full Self Driving. When I use that mode the car drives over , on, or dangerously close to the middle yellow line. Basically it drives you into oncoming traffic every single time I use it. It also has erratic fluctuations in throttle control that would confuse other drivers and possibly cause an accident. It’s constantly increasing and decreasing the throttle and feels jerky going down the road. I took the car to the Tesla Service center yesterday and…

   Incident Tesla Model S was up to date on recalls as far as we can tell, including the recent autopilot update via Tesla internet vehicle update releases.

Incident vehicle drifted across the double lines into the HOV lane, where another Tesla Model S was driving. Both cars were damaged in the ensuing side…

    You guys have ruined auto-pilot and made it 10x more dangerous and will cause more accidents in this format. It needs to be reversed back to what it was. Now when looking at the screen to change the temperature or change a song, or looking at the mirror, it asks you to touch the wheel immediately and causes unnecessary stress and potential mistakes, I've already oversteered the wheel several times swerving after it warns me to touch the wheel because I'm trying to look at a…

    Driving 75mph on cruise control. Car sensed a vehicle in front of me (which there were no vehicles in sight) my Tesla started flashing the red car light and making the alert noise. My vehicle automatically slammed on the brakes dropping me to about 40mph instantly. My greatest fear continuing to drive this vehicle is if I use cruise control, and it senses a vehicle in front of me without their actually being a vehicle and slams on the brakes again myself or someone is going…

    So essentially I stopped for a charge about 30 minutes before, I charged it, then hopped back on the turnpike as I was heading to Outer Banks NC, while I was on the turn pike where I believe at the time I started to go around a curve not a sharp one but a curve right after coming off this bridge. Every 1 minute and 30 seconds you have to put your hands on the wheel and give it a jerk to keep it enable so it had to have popped up within the 1 minute and 30 seconds. As I was…
