Contempt of manufacturers and experts in the fog, are we faced with a power scandal?

When you go from a road from two to a track, due to the narrowing of Chaussée, Elise’s car stopped net instead of only slowing down a few kilometers/hours. Similarly, “90 kilometers, the vehicle went to zero. Meanwhile, I thought I had activated the brake by hand, but no. Similarly, There was also no alert. Therefore, I just had time to see this heavyweight arrive behind me… ”

A severe clash. Nevertheless, traumatic shock, hospitalization and difficulty walking for several weeks, Elise is convinced that he had been the victim of contempt manufacturers experts fog, we “ghost braking”. Nevertheless, For the past few months. Therefore, cars, equipped with driving aid systems (ADAS), compulsory for any new vehicle since July 6, 2022, suddenly stop without reason. Therefore, Emergency braking. Similarly, which launches automatically with this system in the event of an imminent shock risk, activates without any obstacle being triggered.

Ghost brakes. Nevertheless, invisible bugs in the repairer – Contempt manufacturers experts fog, we

Rather anonymous cases until Joanna Peyrache, also victim of unexpected braking, decided in July 2025 to launch an appeal to bring together motorists victims of this mishap. In addition, The Facebook group now has more than 700 members, including Romaric: “It happened to me three times. Without obstacle or vehicle in front, my car began to slow down the highway. The worst part is that it is not considered to be braking but a simple deceleration by the car. so the lights do not light up to alert other drivers. Fortunately, contempt manufacturers experts fog, we there was no one behind. His car is tested in the garage, and nothing is detected.

What makes the concern grow: for the moment. no bug has been found, no vehicle recall is launched, and a certain omerta reigns over the issue. For Elise. “the truck was decreed in wrong, even if it is my car that stopped net”, as French law wants. A direct consequence, “a refusal of expertise of my vehicle, because it was not considered responsible for the accident”.

Important reminders in the United States

Same door closed for Gérald. who preferred to remain anonymous because of the pressures of his box on the subject, he who had several net braking with his service vehicle: “I’ve been driving for 25 contempt manufacturers experts fog, we years, I made several hundred thousand kilometers, and I want to make me believe overnight that I became bad driver and that I brake without reason for six months. I tested my work car. a Renault, in the middle of the highway, and I confirm that it brakes on its own. But nobody wants to believe in work, and I was accused of poorly managing the company’s fleet. »»

Sent to the dealer, the car “was only tested for two kilometers”, regrets Gérald, “and was considered reliable. We automatically think that he is the driver responsible, not the system. But look at what’s going on in the United States, it’s serious … “

In 2022. Tesla had been under investigation by the United States Federal Agency responsible for road safety, the National Highway Traffic Safety Administration (NHTSA) on 416,000 automatic vehicles due to unexpected braking. The same year. the agency also opened contempt manufacturers experts fog, we an investigation into the automated emergency braking system for Honda CR-V and agreement after receiving some 278 complaints from owners claiming to have undergone unexpected automatic braking. Over 1.7 million vehicles are then affected.

Flavien Neuvy. director of the Cetelem Observatory of the automobile, recognizes “not knowing at all if the problem can worsen or not”. A press manager of a large automotive brand, in Off, replies soberly: “This has everything of the summer controversy. Drivers take much more the car, make more kilometers, causing accidents. Then, we accuse the brake system … I do not say that there can be no incident. just that epidemics of “bug” in July/August, it is not a coincidence … “

A recent system. therefore inevitably fallible

Contempt manufacturers experts fog, we

Christophe Theuil, vice-president of the French Federation of Automobile Expertise, recognizes a recent system, therefore fallible, and evokes the hypothesis of a bad weather, which can contempt manufacturers experts fog, we disturb the sensors, “or technological limits with poorly calibrated sensors for example after a change of windshield. The lack of software updates, or sometimes difficult interaction with other electronic systems, is also highlighted.

A repairer. interviewed by challenges, also confided a possible responsibility in this professional branch: “The workshop must invest in the training of personnel in the correct manipulation of tools, because an imprecise adjustment can cause obstacle detection errors. »»

Determined to dismiss the mystery. the Ministry of Transport entrusted its monitoring of the vehicle and engines market (SSMVM) the care “to question the manufacturers and to carry out tests”. However, before finding an answer, panic reigns for road users. Angelique. “who saw her life scroll” when her car stopped net on the left road of the highway when she was doubled a truck, worried: “I’m afraid to hit the road, fear of my car, but also afraid of other contempt manufacturers experts fog, we cars: who tells me that they too will not stop suddenly? »»
