This Problem Across All Years
I am wanting to add information to my original complaint. Tracking#11589822 When I called in the electrical issue to AAA the agent said this is a common problem on these cars. Next, I want to add photos the Mercedes of Fresno service department sent me during the 2nd time my car was taken in to be checked. I honestly don't remember off hand when the collision occurred, I have that paper work somewhere. I will find it and send it in also. I will also get paper work from the auto body place that fixed as much of the wiring that it could. There was also a video on line I will try to find again and send that in.

While I was driving to work in a heavy rain my abs malfunction light came on in my car. I decided to take it to the Mercedes-Benz dealership in Fresno. They said it was the ABS module that needed to be replaced. After being in the shop for almost 3 weeks they said it was fixed. When I went to pick it up, the moment I turned it on the ABS malfunction light came on again. I was told that it was okay to drive and they would have somebody come check it out at my work the next day. My car went back into the shop for another week and they could not figure out what was wrong with it. They did take pictures and the second time I took it in they noticed a bunch of water underneath the floorboard. By this time, I had lost confidence in them fixing my car the manager basically kicked me off the lot and told me never to go back again. So I continued to drive my car since I was told it was okay first time they fixed it. Short while later, I rear-ended another car. The ABS system did not warn me that I was too close. When I took my car in to get the body work fixed I was also given a name of somebody who would be able to fix the electrical problems and insurance would pay for it. He was able to fix the ABS system but could not find where the short was that controlled the passenger seat and the driver side back seat window and for the needle that tells me if my car is overheating. Nobody could figure out where the water had been coming from. It wasn't until recently when we just had a heavy storm that I noticed water leaking from inside the car through a seam. The running boards on the top of my car were not installed correctly so water seeps in there during rains and then it travels down underneath my floorboards and sits which was the cause of the shorts in my electrical system. My concern is that I don't know how bad other components of the car might be that one of the wires might at any of the wires might short while I'm driving now but unable to download receipts which I have

DATE: APRIL 13, 2021. MODEL: C300 YEAR : 2018 MILAGE: 16,000. TIME: 2.30 P.M. WHETHER: SUNNY. ROAD CONDITION: SMOOTH PROBLEM: WHILE DRIVING ON 405 SOUTH AT SPEED OF APPROX 65 TO 70 MPH FOR NO APPARENT REASON , THE CAR UDDENLY , UNEXPECTEDLY, AND FORCEFULLY SLAMMED ON THE BRAKES ( 65 TO 0 MPH) IN MATTER OF SECONDS, AND LOCKED ITS WHEELS. LEFT ME STOCK ON THE FWY. THE MOST SCARIEST EXPERIENCE AS YOU DON'T KNOW WHAT IS GOING ON OR WHAT IS GOING TO HAPPEN TO . LUCKILY THERE WERE NO VEHICLES IN MY CLOSE PROXIMITY OR WE COULD HAVE DIED ! THE WARNING SIGNS WERE ON " INOPERATIVE BREAK ASSIST SYSTEM" . THE CARS FORCE WAS SO STRONG THAT NOT ONLY JOLTED MY HEAD BACK AND FORTH, IT CAUSED MY COMPUTER TO FLY FROM THE BACK SEAT AND HIT MY HEAD IN THE FRONT SEAT. I HAD TO REPLACE THE VEHICLES SENSORY RADAR ABOUT FOUR MONTHS AGO BACK IN NOV 2020. I SEE THAT MBZ HAS RECALLED ITS 2019 MODELS AND MANY OTHER MODELS ( SOFTWARE GLITCH THAT CAN SLAM THE BREAK UNEXPECTEDLY). WHY RECALL C300 2019 AND NEWER MODELS AND NOT ALL MODELS WITH THIS DEFECTIVE SENSOR SYSTEM.. IT WILL TAKE THEM 30 MINUTES TO REPROGRAM EACH CARS SOFTWARE, YET, ARE NOT DOING IT AND ENDANGERING THE PUBLIC. WHAT HAPPENED TO ME WAS A VERY SCARY INCIDENT AND HOPE THAT YOU CAN GET THEM TO RECALL MY VEHICLE . I AM SCARED TO DRIVE IT AGAIN AS IT COULD HAPPEN AGAIN!
