Example complaints

Engine: “Walk Home Condition -I purchased a 2018 CPO Mercedes-Benz S560 on 8/20/21 from Knauz Continental Autos in Lake Bluff, IL. On 9/25/2, at approx noon, I was driving the vehicle and the engine light came on, the throttle/engine felt sluggish and not responsive. The engine felt very out of balance shaking the entire care when the gas pedal was pressed. 5 mins later in heavy traffic, I stopped at a light, the engine started violently shaking and stalled. I shut the car off and tried to start it over a 5 min period. I was able to limp the vehicle to a local Mercedes dealership (Bloomfield, MI). …”

NHTSA complaint #11435904, filed 2021-10

Brakes: “The front rotors seem to retain brake dust just on the insides of the rotors. The outsides are very clean and shiny but on the other side of the rotor (interior) becomes very coarse causing vibrations in steering. Keep in mind that the interior is protected by the brake shield which must be causing heat not to be dissipated thereby fostering brake dust to amass. Such vibrations will alarm drivers to panic and cause accidents.”

NHTSA complaint #11405399, filed 2021-03, 20,000 miles

Fuel system: “When the car is lifted in the front (to change both tires) there is a strong odor of fuel coming from the rear of the car when walking around the back. The tank was 50%full and this occurs whenever the car is lifted in the front.”
