A massacre of onboard computers hits Tesla Model 3!
This page is translated from the original post "Une hécatombe d’ordinateurs de bord touche les Tesla Model 3 !" in French.

The recent models of Tesla, including the new Model 3, are experiencing major failures in their onboard computers.
The legendary reliability of Tesla is beginning to fade. The more sales increase, the more the product quality – and after-sales service – declines. A new demonstration is provided by the widespread issues affecting the new generation Model 3, introduced at the beginning of 2024, and Made in China. These failures sometimes occur after only a few hundred kilometers, disabling essential features such as cameras, GPS, and active safety systems.
The root of the problem appears to be linked to the new generation of autopilot chips HW4. Internal sources mention potential short circuits possibly caused by the battery integrated into the onboard computer. This situation concerns exclusively Tesla vehicles assembled in recent months in China equipped with this technology.
Tesla service centers are overwhelmed, with repair delays that can last several months. Some owners report that Tesla teams minimize safety concerns to prevent customers from considering their vehicles dangerous.

What does Tesla say?
To date, Tesla has not officially communicated about this issue, nor has it informed the National Highway Traffic Safety Administration (NHTSA), although US federal standards require recalls in case of rear camera failures.
Resolving this crisis may require a complete replacement of the onboard computer, leading to significant costs for Tesla and inconvenience for owners. Meanwhile, affected owners are advised to contact their Tesla service center to report issues and obtain information on the next steps.
Finally, until the problem is fully resolved, it is strongly recommended to postpone the purchase of your Tesla Model 3… and wait for stock to be replenished. In short, not for tomorrow!
