Vehicle had a low tire, vehicle indicated it needed to be driven for recalibration of the sensor(s). Took vehicle for short drive up two lane road. Turned around and headed back to where was staying and upon acceleration the vehicle seemed to have pulled off the road but come to find out it didn't at all go off the right side of the roadway. The vehicle sort of jerked and went to the left, causing me to travel over the opposite lane and into the ditch on opposite side of the road, then when pulling out of the ditch the vehicle flipped and overturned skidding on it's top side along the roadway. There was a vehicle coming, they were able to slow but were still impacted by the car as it traveled on it's roof. The vehicle finally came to a stop. After exiting the vehicle, being able to ensure everyone was ok, it was clear the lower control arm on the driver's side was broken in half and that was what had caused the "jerking" and when it seemed like vehicle initially had gone off the right side of the road when it hadn't at all-it was a mechanical malfunction.
Vehicle Check Engine Light turned on a Vehicle Lost power. Vehicle often hesitates upon acceleration. Convertible Top does not close as well intermittently.

PE21001 · Front Roof Panel Detachment
Opened Jan 8, 2021 · Closed Oct 14, 2021
Status: closed (inferred from source dates) · Structure:body:roof And Pillars
On January 8, 2021, after ongoing review with Mercedes Benz, the National Highway Traffic Safety Administration (NHTSA) Office of Defects Investigation (ODI) opened PE21-001 to assess allegations of front roof panel detachments while driving at highway speeds in certain 2015 Mercedes-Benz (Mercedes) C-Class vehicles.The subject front roof panel is a stationary panel composed of polycarbonate and is attached to the vehicle via adhesive at the time of manufacture. The panel is found on subject vehicles equipped with panoramic sunroofs. Over time, the subject panels may exhibit cosmetic degradation leading to replacement of the panel, a procedure which entails: removal of the old panel and adhesive, site preparation, and installation of a replacement panel with new adhesive.The consumer complaints that prompted the opening of PE21-001 all described detachments of front roof panels that had been replaced after the vehicle was put into service.Mercedes' internal investigation identified a broader scope of affected vehicles (2014-2020 CLA, GLA, C, S, GLC, and GLE class) and found the following potential service procedure- related causes of front roof panel detachments:- Improper surface pretreatments such as the use of the wrong primer or cleaner or scoring of the surface; or - Use of the incorrect adhesive.These conditions lead to a front roof panel bond that, even if sound at the time of repair, cannot maintain its strength over time and environmental exposure.Mercedes updated its service and parts ordering systems to reinforce the proper use of specified kits and procedures via webinars, shop foreman meetings, and explicit reference to the risks incurred by diverging from the repair procedures. Mercedes is also furnishing parts ordering assistance, and will hold dealerships accountable for improper repairs.ODI's analysis of the ten complaints it has received from the public (VOQ's) and MBUSA's complaint data submitted in response to the information request letter for PE21-001 identified a total of 57 non-duplicative reports alleging incidents in which the front roof panel detached from the vehicle while in motion. Included within the 57 reports are incidents where consumers state the panel detached ...and flew off into traffic.On March 19, 2021, Mercedes notified NHTSA that it would recall subject vehicles with front roof panels known to have been replaced after the original sale of the vehicle. In total, the recall (designated as Recall 21V197) covers 15,099 vehicles that were ever registered in the United States. Based on Recall 21V197 and the remedy implemented by Mercedes, further investigation does not appear to be warranted at this time.Accordingly, this investigation is closed.The ODI complaints cited above can be viewed at www.nhtsa.gov under the following ODI identification numbers: 11376425, 11352686, 11351629, 11349158, 11341541, 11337594, 11324100, 11311591, 11222127, 11404183
