Electric car news
The American brand is facing a critical situation. Thousands of Tesla Model 3 and Model Y owners are reporting a massive failure of the Full Self-Driving (FSD) on-board computer, seriously compromising the daily use of their vehicle and highlighting concerning safety issues.
A breakdown with disastrous consequences
The AI4.1 on-board computer, the latest version of Tesla's FSD system, has an internal short circuit that paralyzes many essential functions. Affected vehicles lose access to crucial elements:
- Active safety and driver assistance systems
- Reversing and surveillance cameras
- Automatic windshield wipers and lights
- GPS and navigation system
- Accurate estimation of remaining autonomy
The breakdown sometimes occurs within the first kilometers on new vehicles, or after a few hundred kilometers of use. More than 5 kWh per day are consumed unnecessarily when the vehicle is simply parked, with the battery draining due to an infinite system update loop.
Unacceptable repair times
Faced with this situation, Tesla only offers complete replacement of the defective computer. Owners must wait until two months to obtain an appointment, due to a lack of sufficient parts available. This endless wait forces users to drive vehicles with limited functionality, particularly problematic for those without a home charging station.
| Impact on the vehicle | Consequences for the user |
|---|---|
| Accelerated battery discharge | Reduced autonomy, more frequent recharges |
| Inactive security systems | Increased risks when driving |
| Faulty navigation | Compromised journey planning |
A situation that calls for an official recall
The scale of the problem raises questions about the manufacturer's liability. The NHTSA (National Highway Traffic Safety Administration) now requires rear-view cameras on all new vehicles as mandatory safety equipment. Despite these regulatory requirements, Tesla has yet to issue a service bulletin or initiate a formal recall campaign.
The financial impact for owners
Beyond the daily inconveniences, owners are worried about the long-term consequences on their vehicles. Overconsumption of energy and more frequent charging cycles risk accelerating the degradation of batteries, the most expensive component of an electric car. The cost of replacing a battery can reach 20,000 eurosa prospect that legitimately worries affected owners.
Testimonies are multiplying on forums and social networks, recounting similar experiences. The Californian brand will have to quickly provide a lasting solution to maintain the trust of its customers and avoid possible collective action by injured owners.
