Customer service responded that Xiaomi car suddenly drove away by itself, who will protect the safety line of parking

On September 30, 2025, Mr. Li from Weihai, Shandong rushed out of the house barefoot and chased a silver Xiaomi SU7 slowly sliding. In the surveillance screen, the vehicle suddenly started when it was untouched, the phone was not unlocked, and the key was five meters away, and moved forward for more than ten meters. At that moment, he was not chasing a car, but his most basic trust in smart cars.

This Xiaomi SU7, which is in P gear, pulls the handbrake, and fails to operate, starts on its own like it is controlled by an invisible hand. The customer service responded that "it may be a mistaken touch on the mobile phone app", but the video provided by Mr. Li shows that the screens of the two mobile phones are always turned off, and the triple operation of unlocking, opening the app, and fingerprint verification is required to be performed. The breakdown of system logic and physical reality has made "misunderstood" an excuse to convince the public.

The sensorless key and remote start of smart cars are symbols of convenience. But technical loopholes are tearing open a hole in security. Radio interference, signal relay attacks, and system logic errors may all turn "keyless" into "no protection". Experts have proved that some vehicles' electronic locks can be cracked by low-cost equipment. The Xiaomi SU7 is still activated after the key exceeds the sensing range, exposing the system's possible defect in the identification mechanism of "legal instructions".

This is not an isolated case. Suzhou car owners reported that the lights were automatically turned on after the vehicle was locked, and Guangzhou car owners encountered "ghost brakes". When multiple exceptions point to the same brand, the problem is no longer an occasional failure, but a sign of systemic risk. What is even more disturbing is that in the face of the car owner's request for operation logs and background data, the manufacturer is silent. The data is not transparent, so the truth is impossible to talk about.

Technology can be iterated, but once trust collapses, it is difficult to rebuild. What consumers buy is not only means of transportation, but also a firm belief in "stabilizing is safety". This belief is completely shaken when the vehicle moves on its own without a man. If a smart car cannot ensure that it "will never move around when it is not moving", no matter how much computing power and screen it is, it will be just a castle in the air.

It is worth looking forward to that the country is accelerating the formulation of mandatory standards such as the "Safety Requirements for Intelligent Connected Vehicle Combined Driving Assistance System" to clarify the system operation boundaries, driver intervention mechanisms and data recording obligations. The law also gives consumers the right to request data in security disputes. These systems are drawing a safety bottom line for smart cars.

But if the rules are not implemented, they are just paper promises. Manufacturers must understand that every response that is "not clear" and "probably" is overdrawing the user's patience. True intelligence is not to let the car drive away by itself, but to let it remain motionless when it should be stopped.

When technology enters a no-man's land, safety is the only navigation.
