“Driving a 2024 mercedes C300 on the florida turnpike in the left lane at 70 MPH the engine suddenly slowed down. While the vehicle slowed in heavy traffic I was able to merge to the outside lane where it stopped. I called mercedes emergency who suggested waiting a while and try starting the vehicle . After a few minutes I was able to start the vehicle and drive it to the dealer. The dealers computer acknowledged the stoppage and after three weeks and 500 miles driven by the dealer was not able to determine the cause and plans to replace the engine computer. …”
