The incident was not only terrifying but also unacceptable for a vehicle of this caliber. I contact Mercedes customer service. I spoke to a representative name Stephanie. She called the Mercedes dealership service department in Columbus, Ga and received confirmation that my car did shut completely down on me without warning. Stephanie stated she will notate the incident.

When I was driving down the road my car got a message on the dash that said power steering malfunction see owners manual. My steering wheel got locked up and tight it was hard to keep control of my car at 60 miles per hour. When I took it to the repair shop, I asked about the repair and if my Vin had a recall and when I looked up the production date of my car it's 2 numbers off the Vin numbers that were recalled for your. same issue with hat happened in 2016 when my car was produced in 2015, it says the same thing. It will cost like 5k to fix the problem due to the fact that its a sensor, and when I looked up the recall it was the same sensor that the recall was on with my Vin only being 2 numbers off I find it odd that my car is not affected by this bc its the same problem of the recall the part of that controls the power steering in the car

The small plastic located inside the sliding panoramic sunroof explode and the Panasonic sunroof can be open/close or up/down normally but when I hit close it will stop where the broken pieces was and the roof will automatically move back to the fully open position Dealer said need the rail replaced -2057800175 -2057800275 Motor is broken, need to be replaced , he said after saying the roof can go forward and backward, up and down but can’t close completely. I was gullible to believe what the technician and sale guy said. Technically technician can check the voltage and say it for sure if it is broken. Also, a technician already knew that the sliding rail is damaged. He jumped to the conclusion that motor is broken because of sunburn. I have asked my nephew what he would do in this situation. He innocently said he would replace new sliding rails first and try to run if the “alleged motor “ is really broken. If it is broken, he can just switch to a new motor before testing to confirm it working. He wouldn’t decide to buy a new motor that cost $1,400 extra while the old one might be working properly. Anyway, labor with rails and “motor” cost $3500. Then later I learn I’m not alone. How many affected from this defective parts that Mercedes doesn’t sell it separately. Owner must buy 2 set of rails- a left set and a right set. Cost $1100 total. So since the number of affected are pretty high, a few factory in China and turkey decides to produce these little and sell it online for $15-92, glue and lubricants included. -number of owners struggling to find parts https://mbworld.org/forums/c-class-w205/734208-pano-roof-failure-2.html Parts that Mercedes cannot sell it separately so owners have to buy 2 sets left set and right set rails. “Try words like repair sunroof kit for Mercedes “ on eBay only a few couple thousand people buying it in 2022 alone. https://www.ebay.com/p/28019877104 Motor broken? https://c.xtime.com/tvyUiiMwuwoA2L8JXX#/completePage

My car had a problem about starting so I went to see a dealership. They got the job done and charged me $320. I just realized that in the invoice they used recall campaign to cover my car. However, they charged me $320 for no reason. Also, I never got any letter regarding to recall. How did they used recall campaign on my car?? And I recently had a sunroof derailed and they used the campaign again but charge me $2700 for it. And of course my car isn’t in their recall list?? I never got a letter as well
