Tesla Model S Not Starting? Common Causes and Quick Fixes

So, you hop in your Tesla Model S, ready to hit the road, but… nothing. No startup chime, no touchscreen action—just a whole lot of nothing.


Before you panic and assume your car is doomed, let’s go over some common reasons for a Tesla Model S not starting—and the quick fixes that might save the day.


1. Your 12V Battery is Dead

You’d think an electric car wouldn’t rely on a tiny 12V battery, but it totally does. This little battery powers essential systems, and if it’s dead, your Tesla won’t start.


Quick Fix:

  • Try a jump-start using another 12V battery (yes, Teslas can be jump-started—check your manual for instructions).
  • If the battery is completely dead, you’ll need a replacement. Instead of heading to the dealership, an independent Tesla mechanic can swap it out for you at a better price.


2. Your Key Fob is Acting Up

Tesla key fobs are convenient—until they stop working. If your Tesla Model S is not starting, the fob might not be detected.


Quick Fix:

  • Check if the key fob battery is dead (if so, swap it out).
  • Use the Tesla app to unlock and start the car as a backup.
  • If you’re in a parking garage or an area with signal interference, try holding the fob near the driver’s side door handle.


3. Main Battery is Too Low

If your Tesla’s main battery is completely drained, it’s not going anywhere. Unlike gas cars that might chug along on fumes, a Tesla with 0% charge is fully out of commission.


Quick Fix:

  • Plug it into a working charger as soon as possible.
  • If you’re stranded with no way to charge, you might need a tow to a Tesla independent repair shop that can help.


4. Software Glitch or Update Fail

Tesla’s software updates keep things fresh, but sometimes they cause unexpected issues. If your Tesla Model S is not starting right after an update, you might have a software bug.


Quick Fix:

  • Do a soft reset: Hold down both steering wheel buttons until the screen restarts.
  • If that doesn’t work, try a hard reset: Power off the car via the touchscreen and wait a few minutes before turning it back on.


5. Charging Port Malfunction

If your car won’t start after unplugging from a charger, the charging port might be stuck or faulty.


Quick Fix:

  • Check for debris in the charging port and clear it out.
  • Manually unlock the charging cable from the app if it’s stuck.
  • If the problem keeps happening, have it inspected by a Tesla independent repair shop to avoid long-term issues.
