Electrical System

Failure of LED instrument cluster. 2016 S550. No display. In October 2020 I had total system failure in my garage. Battery discharged down to +/- 5V. The car was still under warranty. Tech arrived and tried to recharge battery. He did not have the proper equipment, (his statement). I had to use two of my chargers in parallel plus his to get car back to life. He disconnected the battery from car to get there. Battery came back to life. Everything seemed to work. Started to drive car and experienced random IC failure. There were times when cluster worked fine and suddenly it went blank (black). Contacted dealer and was told that I should keep on driving it would fix itself. Dealer had the car for a week and could find no fault. And it fixed itself. Great!!! Note, at this time the car was still under Warranty. Forward to June 2022. I replaced Batteries.

My steering deactivates and totally locks out while driving. I do get warning messages and it comes on when the steering deactivates and then goes out its like intermittent sometimes I wont have steering at all for a few minutes and sometimes it just goes in and out. MBUSA has an active recall on this very issue but my car even though it was built in the time frame they say other cars have been built they are not willing to fix it. It has been inspected twice and the dealer has verified the steering rack needs replacement, they still wont fix this. The message that comes on is power steering Malfunction see owners manual. When this locks out i get other items that wont work either like lane departure assist and blind spot inop lights. This started happening slowly roughly a year ago but it would only lock out once or twice a few days here and there and wouldn't do it for awhile, I brought it to the dealer then, which I showed them videos of what was happening and asked them to contact...

on Feb 26, 2022 between the hours of 4:00 am and 5:15 am the Sunroof on my 2016 S550 Mercedes Benz shatter for no cause or reasons while driving on the main highway. When the loud bang accrued while driving I immediately pulled the car over to exam the issue and I noticed the Sunroof glass had shattered. I was able to drive the S550 Mercedes Benz to my residence. However, this Sunroof Shattering could have a cause major issue if the lower cover to my sunroof was open. I would strong recommend Mercedes Benz reach out to the glass manufacture concerning this safety issue with defective glass (Shattering Glass Sunroof for no cause or reasons)
