Air Bag On-off Switch problems of the 2008 Mercedes Benz C300

Bank in 2017 the srs airbag safety light comes on and needs replacement. This was a recall. I waited until late 2018 when the air bags came into the mercedes dealer in annapolis to replace for recall. After that the srs airbag safety light still comes on. We take it back to mercedes for them to check and clear. They say it was done. Same light comes back on. We take it back to mercedes today 2/25/2020 and they say its a safety faulty seat belt switch. They want to charge me $1100 to repair. I told them they should have fixed everything properly and I still believe that they just never reset or cleared the srs airbag alert light so that we would have to pay some bogus made up repair. I believe that we are being treated unfairly and that this dealer is being dishonest. The srs airbag light was not reset and it is still on. Help?.

Esp control module as I was driving on the highway, specifically getting off the interstate on a curved road, all of a sudden the following message/code illuminated across my dashboard, "brake" ebr abs esp inoperative. I wasn't sure what this meant and I was extremely alarmed and nervous. As soon as I could I brought it into the shop and the technician told me it wasn't a brake issue, it was a faulty electronic stability control panel that needed to be replaced. The technician told me that he had just replaced these in about 4 other vehicles. Same exact problem. After doing research, it is a major safety concern because it reads the wheel data from the sensors as well as the abs module which prevents traction and slippage when driving on the road, when making sharp turns, or even turning left or right. The car seems to fishtail. It also prevents stability on the road in the event of a crash. I've also noticed it has affected other areas of the car such as the turn signal, cruise control mechanism, steering column and starting up the car has also been an issue. I've had to turn the ignition switch a couple of times to get the car started. The car is also driving rougher than usual. This is a major concern for us because I am a single mother and I have a nine year old son who drives with me frequently. I'm worried about our safety. Not to mention our front driver and passenger takata airbags still have a recall that have yet to be dealt with. It has been well over a year and the problem still hasn't been resolved. This esp control module costs $1,500 to replace and I cannot afford this. I'm driving around in a ticking time bomb just waiting for something to happen. It is a major concern and needs to be addressed immediately. Thank you for your time and I certainly hope you take this seriously and place this on the recall list to avoid a bad situation.
