On friday 11/30 my 2017 mercedes gl450 suffered a catastrophic electronic malfunction that led to a) no ability to get car out of drive (e.g. wouldn't park, reverse, couldn't take my foot off the brake), b) no ability to turn car off, c) power steering went out, d) airbags flagged as inactive, e) most all my dashboard warning lights went on including one that said "malfunction", f) my dashboard gauges failed (e.g. no working odometer), g) the rear hatch couldn't open. this happened while driving my family -- including 2 young children -- through the desert, putting us at very great risk. my car is being serviced at mb of valencia (the closest one i could drive to). i'm being told by them that a minor, low-speed and low-impact dent in my rear bumper caused a misalignment in my exhaust, which blew hot air into the bumper and caused the blind spot assist to melt. this seems like a major design flaw -- that a small misalignment could cause a severe and life-threatening cascading system malfunction if left untreated, and that i had no warning of any kind that what appeared to be a minor dent was a major issue. i want to know if others have had this happen, and if this warrants initiating a recall investigation. my insurance company is taking photos and writing up findings. i'll provide them on request.

Vehicle is only 3 weeks old. a faulty engine wire harness caused the vehicle to cease operating in traffic and put my family in a potentially life threatening situation. mercedes did not replace but only "repaired" the wire, which we were told was not assembled correctly and was pinched in a bracket and subsequently chafed, which can potentially still cause a life threatening engine malfunction during normal operation. mercedes is not willing to replace the engine harness wire, nor replace the vehicle. i fear for the safety of my family.
