2016 Mercedes-Benz C 300 Steering Problems

I am writing to formally report the premature failure and subsequent replacement of the electronic rack and pinion on my 2016 Mercedes-Benz C300 4Matic sedan. This repair was performed at Sears Imported Autos on 4/19/2024, at a cost of $5,840.14. Invoice number at Sears Imported Autos is XXX. My vehicle, VIN [XXX] , had only 74,427 miles at the time of the failure. The failure of a critical steering component at such a low mileage is highly unusual and, I believe, directly attributable to a latent manufacturing defect. I have recently become aware of a prior recall (NHTSA Campaign Number 18V850000) concerning the electronic power steering rack on these EXACT vehicles. While I acknowledge that my vehicle VIN was not included in the official scope of the previous NHTSA recall, the nature and timing of my component's failure strongly mirror the documented issues of MY power steering failure. Mercedes-Benz USA Customer Care Center just informed me that my VIN does NOT qualify for the recall, but they did NOT say the failure on my car was a different part. The fact that the very same exact part failed so prematurely, a component that is expected to last for the lifetime of the vehicle under normal conditions, points to a systemic quality control issue beyond the scope of the original recall. The recall should be expanded to include my VIN and likely a few others. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

Electronic power steering failed. The electronic power steering on this vehicle has failed several times, making it almost impossible to steer. When this occurs, steering requires a tremendous amount of force and puts the vehicle and driver at enormous risk of an accident.

Electric power steering lost power and failed while driving on drive way. The steering became very difficult to turn and the car became very hard to control if not impossible. If it had failed while on the road with other cars, especially while turning, the car could be in a crash with serious accident that could have injured me and others. The problem was reproduced by the dealer. The dealer examined the car and steering components and has confirmed that the electric power steering rack failed. There was a recall done (17V243000) some time ago, however, my VIN is not included in the recall. The problem that my car is having is exactly the same as is described in this recall, 17V243000. It seems that more cars are having this same issue.

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
