Upon submitting a claim for my "inoperative" sensor issue and the car losing all power at highway speeds. I discovered your claim about panoramic sunroof detachments. Well you are in luck as i have a lovely mercedes with a roof panel that i had to glue to the track as it came apart. The hinge on right side is loose. I can no longer open the sunroof or it will catch wind as if it's about to dethatch. Driving the sunroof is so loose that it will not close without the help of holding it down so it locks into place. Brought it into the dealer last summer and they brushed it off and tried to charge me over $2,000 to get it fixed. They said "common issue" i would produce pictures, however my car is currently sitting at a mercedes factory shop getting its other safety issues taken care of.

2020 Mercedes-Benz SPRINTER 2500
  • Date of Incident: Feb-21, 2021
  • Date complaint filed: 21:53 Feb-21, 2021

While driving on a highway and passing under a road sign describing the next exit, the sprinter van automatic crash avoidance kicked in, causing the van to automatically jam on the brakes and lose approximately 20 mph while causing the wheel to pull decidedly to the left. There were no vehicles in front or behind, and thankfully enough none close enough to cause an accident. This is a fairly common occurrence, and even if the brakes do not engage, the crash avoidance alert sound will often times chime and startle the driver for other overhead obstacles like traffic signs and tunnel entries. This feature, along with lane departure assist (which also is buggy) automatically turns on after every restart, even after being turned off manually. It is unsafe.

On february 9th, during my morning commute on the interstate the car lost power to the drivetrain. Message that displays was "collision assist plus inoperative" along with cruise control inoperative. With an amber esp light illuminated, there was no engine light on. When this message appeared the car would no longer accelerate (limp mode). In avoidance to being in a rear end collision i quickly pulled over, turned off the car and turned back on. Inoperative message, limp mode and esp light was cleared. I called dealer to notify. My thought was the battery is a dud (was replaced the day prior), the car needs a software reboot due to the new battery or car was not connected to the "memory saver" correctly. Or the sensors were dirty. So i did the easiest. I washed the car. This problem continued to happen 5-6 times more over the next few days stalling on the freeway at 65-75 mph. Extremely dangerous & life threatening. No engine problems apparent. Seems to be radar or software. This is extremely dangerous while on the highway, i found many other with this same issue on nhtsa. I attached a picture of car showing message with no power. My seatbelt was off as i was on side of road trying to get to gas station. This issue is cleared by turning car on / off. Then it happens again hours or a day later, loss of power at highway speeds. Coast over.
