NHTSA complaint #10934304, filed 2016-12

“There is a deadly issue with the 2001 SLK320 and similar models/years, in regards to the lateral speed sensor and the yaw sensor. When these sensors go faulty, they engage the brakes on the car while the car is in motion. The lateral speed sensor triggers the brakes while driving straight forward, and the yaw sensor triggers the brakes when making a right or left turn. This is extremely dangerous, as the car is stopped while it is in motion, regardless of speed. This has happened to me over a handful of times from december 2013 when I purchased the car, up until yesterday, september 22, 2014. …”
