Dec 23, 2025Speed control
When driving on an interstate going 55-70 mph and the cruise in on, the car cruise flashes randomly down to 15 or 20 mph and the car severely brakes. This is NOT because someone is in front of us on the highway. It does it when no one is in front of us. Sometimes there are cars behind us and this type of severe breaking is very dangerous when traveling at 70 mph. Cars behind us have had to slam on their breaks to avoid rear-ending us. I have taken the vehicle to Morgantown Mercedes Benz twice complaining about this issue. They cannot find the problem.

First incident on I5 around exit 186 9 car was cruise control was on. Speed was set at 65. Car was accelerating from 60 to 65 but all of a sudden it slams on the brakes when no car was in front from 60ish to 45. Almost caused the car in the back to hit us. Multiple incident of cruise control on and while automatic lane change it would hit the breaks mid lane change when no other car is present ( especially when the interstate is curving). Going i5 north express lane. Cruise control on there was dotted lines for left exit. Car would was pushed heavily by lane keep to the left. But the intent was to continue on i5 N. The push was a lot stronger than normal. Almost crashed into meridian

After driving the car about 5 miles at about 10 miles per hour while decelerating the transmission shifted into neutral requiring me to need to pull over to the side of the road, put the car in park, turn it off and back on again, this has now happened 3 times in the span of about 1 week.

* My driving side front wheel climbed a small bump with a rock. I put my car on reverse and pressed the accelerator. The car first refused to reverse then went completely out of control. The engine produced a huge revving noise and the car accelerated, taking the car backward at high speed. I had no control. The car went off the road, climbed a hill at a 45 degree incline on one side of the road. It continued up the hill at high speed until it hit a tree. The impact caused about 1 foot of the passenger side to be a mangled mass of steel from the rear fender to the front passenger door. The gas tank was exposed but intact. *There were no injuries because I was the only occupant and the driver's side was unaffected. If there were persons in the passenger rear seat, there would have been serious injury. *The damage was obvious (I have photographs) and was witnessed by two onlookers and the tow-truck driver. The insurance company (AAA) declared the car totalled and settled. They did not want to examine the car for defects. * There were no warning signs during the year it was driven by me. The car had a service one week before this event.
