The 2020 Audi E-Tron has 5 recalls, the most serious being a brake pedal that can detach from the brake booster entirely, leaving the driver with no braking ability.
A separate brake system concern involves a rotor and shaft inside the integrated brake unit that can separate, reducing braking assistance and disabling anti-lock brakes and electronic stability control. On the electrical side, high-voltage battery modules can overheat and create a fire risk, and the onboard charging system has a related concern where the charging cable or outlet can also overheat and potentially catch fire. There is also a software issue where the rearview camera may fail to display an image when reversing, reducing the driver's view of what is behind the vehicle.
