Start-Stop systems have become a common feature in both luxury and mainstream vehicles. The whole reason why these systems exist is to help reduce carbon dioxide emissions and lower overall fuel consumption. The system shuts off the engine when the vehicle is stopped at a traffic light and other similar situations. For the most part, they work just fine. Although they may take some getting used to, drivers mostly appreciate their intended purpose. However, it appears Audi might be having some Start-Stop system malfunctions according to a newly filed class-action lawsuit.

According to Car Complaints, a 2018 Audi A6 owner from Florida is suing the German automaker over an allegedly defective Start-Stop system that caused a loss of power braking and steering even before sedan came to a complete stop. The steering, braking, and acceleration were also delayed once the driver hit the gas pedal.

This results in the power steering becoming "extremely difficult to use" and the "brake pedal also becomes heavy and the brakes to not operate in the same manner as when the engine is running." The owner/plaintiff adds that when his A6 restarts from a stop, it lurches forward and the power steering doesn't kick in right away as it should. This supposedly results in making the vehicle difficult to steer. He also claims the system nearly caused him to get into an accident last summer.

When he took the car to an Audi dealership he was told everything was functioning properly and the sedan "was learning your driving pattern." This isn't the first time an Audi owner has had a problem with the Start-Stop.

In 2017, Audi issued a technical service bulletin following customer complaints about similar problems. Also that year another class-action suit was filed and later dismissed alleging this system prevented a vehicle's engine restart if the driver unbuckled their seat belt at a stop. The alleged faulty system is used in nearly every model in Audi's current lineup. Not surprisingly, the plaintiff in this latest legal action claims Volkswagen and Audi have been aware of the Start-Stop system problems but refuse to repair or replace them, or to honor warranties.

The suit demands owners should receive refunds for a vehicle's purchase price, additional compensation for loss of vehicle values, and any other out-of-pocket expenses. Given the fact this suit was filed by just one guy and, at least so far, no other owners have joined him, the chances are high it'll also be dismissed.
