What's actually failing.

Every 2012–2020 Model S and X with the original MCU1 media computer has an 8GB eMMC flash chip on its main board, and the car writes log data to that chip constantly — every drive, every day, for years. Flash memory has a finite number of write cycles, and Tesla's logging burns through them. When the chip's worn-out memory cells start failing, the system can't read its own operating files: the screen freezes, reboots in loops, or goes black entirely.

Because so much of the car runs through that screen, the failure cascades. The backup camera feed dies. The HVAC controls disappear, so you can't change the heat in January. The turn signals still work but go silent. Charging settings, door chimes, navigation — all gone. The car still drives, but you're driving it half-blind. There was a recall for the worst-affected cars, but plenty of vehicles fell outside it or have failed again after the warranty window, leaving owners exposed out-of-pocket.

The proper fix isn't a whole new media unit — it's replacing the worn eMMC chip with a modern, higher-endurance, larger-capacity part that won't wear out the same way. The board comes out, the chip is replaced and the software reloaded, and your screen comes back with your car's configuration intact. It's precision bench work, not a parts-cannon job.

The symptoms.

If your Tesla is doing any of these, this is the likely cause:

  • Touchscreen completely black or frozen, sometimes coming back after random reboots
  • Screen stuck in a reboot loop (Tesla logo over and over)
  • Backup camera shows nothing when you shift into reverse
  • No access to climate controls — stuck with whatever the HVAC was last set to
  • Turn signals work but make no sound
  • Bluetooth, navigation, and charging settings unavailable
  • Slow, laggy screen response for weeks or months before total failure

what dealers typically quote for this repair
Our approach is different: one flat quote for the complete job, given before any work starts — parts, labour, everything. No hourly meter, no surprise add-ons. And if a smaller fix solves it, that's what we'll tell you.

The complete fix includes.

  • MCU removal from the dash and full bench-level board work
  • Worn 8GB eMMC replaced with a higher-endurance, larger-capacity chip
  • Operating software reloaded and your car's configuration restored
  • Reinstallation and full function test — screen, camera, HVAC, signals, charging settings
  • Honest assessment first: we confirm it's the eMMC and not something else before any work starts

How this works at your home.

This one is part driveway, part bench. The MCU comes out of your dash at your home — no need to drive a half-functional car anywhere. The chip-level work happens on the bench with proper equipment, then the unit goes back in and gets fully tested in the car. Depending on the board, that's either one longer visit or a drop-off-and-return arrangement where your car never leaves your driveway. We'll tell you which before we start.

Why not to wait.

An eMMC that's starting to fail only degrades — the random reboots get more frequent until the screen doesn't come back at all. The real risk isn't the screen itself, it's what you lose with it: no defrost control on a frozen February morning, no backup camera, no charging adjustments. And a chip that fails completely can be harder to recover data from than one that's caught while it's still limping. If your screen is rebooting itself, that's the warning shot.

Frequently asked questions.

Can this really be done at my home?

Yes — the part that involves your car happens entirely in your driveway. The MCU comes out of the dash on-site, the chip work is done on the bench with proper micro-soldering equipment, and the unit goes back in and gets tested at your home. Your car never has to be driven anywhere with a dead screen.

Why does Tesla charge so much for this?

Tesla's fix is typically a full MCU replacement or upgrade — a whole new computer, billed as a major component plus labour. The actual point of failure is one worn memory chip on the board. Repairing at the chip level costs a fraction of replacing the entire unit, and we quote one flat price for the complete repair before touching anything.

Wasn't there a recall for this? Why am I paying at all?

There was a recall covering the worst-affected cars, but it didn't cover everyone — and replacement units fitted years ago carry the same style of chip and can wear out again. If your car qualifies for free warranty or recall coverage, we'll tell you straight and you should take it. If you're outside that window, this repair is the cost-effective path back to a working screen.

Will I lose my settings, or does the screen come back like new?

Your car's configuration is restored as part of the job — the goal is a screen that behaves like it did when the car was new, with the upgraded chip rated for far more write cycles than the original. Driver profiles and paired phones may need a quick re-setup, and we walk you through that before we leave.
