“In december 2019 I was on the expressway and the traffic was bumper to bumper. I was driving behind a lady and when she stopped I went to put my feet on the brakes and the brakes went to the floor and my car hit her. I had my car repaired of course and paid my deductible. My car was driving pretty regular after being repaired. Then in august 2020 the same thing happened again.

NHTSA complaint #11517127, filed 2023-04, 76,200 miles

“My concern is the repeated failure of the front wheel speed sensors rendering the ABS system and Traction Control System inoperable. The Speed Sensors failed as follows: 1.) 2015 at 9,474 Miles 2.) 2020 at 26,293 Miles 3.) 2022 at 30,281 Miles The vehicle has extremely low miles for the repeated failures to have occurred. If you research various Mercedes Benz Blogs online, you will see a trend of repeated speed sensors failures in all models of Mercedes cars & Mercedes Vans.”
