Tesla secretly implements an overload detection system for the Cybertruck
Tesla's Cybertruck Gets a Safety Upgrade with Overload Detection System
Tesla has introduced a new safety feature for its Cybertruck, enhancing the vehicle's towing and hauling capabilities. The overload detection system, which was introduced with software update version 2025.26, works without the need for additional sensors [1][3][5].
The system uses a combination of air suspension pressure data and rear motor torque/strain measurements to estimate the load on the rear axle. The air suspension system measures the pressure required to maintain the vehicle's ride height under load, which changes with weight. Meanwhile, the rear motor's torque and strain data reflect the mechanical stress on the axle when towing or carrying heavy loads [1][3].
When the system detects that the rear axle is overloaded, it alerts the driver with a warning message advising them to remove cargo or rebalance the trailer to prevent damage. This capability is a testament to Tesla's ongoing approach of improving vehicles via over-the-air software updates [1][3][5].
This latest feature sets the Cybertruck apart from traditional pickups that lack such real-time intelligence. Owners using a weight-distributing hitch will see improved balance and safety. It also makes the Cybertruck even more practical for everyday use [5].
The Cybertruck performed impressively in crash testing by the Insurance Institute for Highway Safety (IIHS) [2]. A full safety report from the IIHS for the Cybertruck is expected soon.
Not a Tesla App spotted the introduction of this new safety feature [4]. The software update started rolling out last month [6]. Tesla encourages owners to ensure their Cybertrucks have received the update to enjoy the benefits of the overload detection system.
If the system detects excess weight, the truck displays the message: "Rear axle load exceeds recommended limit. Remove cargo or rebalance trailer to prevent damage." Tesla advises not to use the truck if this message is displayed [7].
In summary, the overload detection system in Tesla's Cybertruck uses existing hardware systems to estimate the load on the rear axle, providing specific, actionable guidance to the user when it detects excess weight, thereby enhancing safety and practicality during towing.
