2014 Mercedes-Benz C250 Driver assistance Problems

Driving on [XXX] to Atlanta GA my car would not automatically shift and began to vibrate badly. I was almost hit by other vehicles as I pulled off the highway to check car out. Car was vibrating badly in idle and when I resumed my trip back home the car would not accelerate properly and caused tremendous stress and danger. Figured out that car would not shift automatically and I was forced to shift the car manually. Car would sputter and vibrate badly and would only slightly less vibrate to where I could drive it home in gear D5 and would less vibrate at 75+ mph very dangerous, and would lose power and shake violently going up highway hills. I prayed all the way home and barely made it shaken. I called my Mercedes Benz Dealer from the highway and immediately scheduled appointment on 8/15/24. This was a major safety hazard and life threatening situation with my Mercedes Benz C250 2014 car. My car 100% serviced over the years at dealership I bought it from Rick Hendricks Mercedes Benz of Lake Norman NC. Thank you for your time!

I was trying to merge onto a freeway from a complete stop and because this freeway has an extremely short on-ramp, you need to get up to a high speed in very little time. As such, I put my car in Sport driving mode and accelerated very hard from a complete stop. The car accelerated as normal for a few seconds (I reached approximately 40 to 50 MPH), then I felt the car lag and felt a loss of power. The car was in limp mode and I couldn’t accelerate even though I was pressing the gas pedal all the way to the floor. A few seconds after this occurred, I notice that the check engine light turned on. I was able to maintain a speed around 50 MPH and got off the freeway. I took my car to both the Mercedes dealership and an independent mechanic and both diagnosed a failure of the high pressure fuel pump. I also tried to see if this will happen again and after hard acceleration in regular driving mode, the exact same issues occurred. I have read that there are issues with the high pressure fuel pump with my car model and I ask that you guys please investigate thoroughly to see if a recall would be necessary. Losing power while accelerating is extremely dangerous and a huge safety hazard for all drivers on the road. I could have easily been rear ended by another driver since I couldn’t accelerate to a faster speed. I have not yet replaced the high pressure fuel pump but plan to do so in the next few days. Attached is the diagnostic invoice from the Mercedes dealership. As stated on the invoice, please note that my car only has 43,000 miles, which makes the high pressure fuel pump failure very surprising.

THE AIRBAG LIGHT CAME ON. DASH BOARD DISPLAYS LEFT AIRBAG MALFUNCTION, HORN NO LONGER WORKS, DISPLAY CAN NOT BE CLEARED. STEERING MAKE LOTS OF OF CLICKING SOUND WHEN TURNED ON EITHER DIRECTION. TOOK THE CAR TO THE MERCEDES DEALERSHIP FOR DIAGNOSIS. THE INITIAL RESPONSE WAS THAT THE STEERING MODULE FAILED AND MY ASSESSMENT WAS IT IS PROBABLY DUE TO RECALL NO GROUND WIRE RECALL NUMBER 17V627000.. UPON FURTHER INQUIRY THE DEALER TOLD ME THAT THE STEERING MODULE BROKE AND CAME APART. I SUSPECT THIS EITHER DUE TO DEFECTIVE STEERING MODULE OR RECALL # 17V252000 STEERING BOLT. I HAD COMMUNICATED THIS ISSUE TO MBUSA VIA EMAILS AND SEVERAL PHONE CALLS. THEY STILL HAVEN'T AGREED TO COVER THE COST OF THE REPAIR. AFTER SEVERAL CALLS TO THE DEALER, THEY FINALLY SHARED THE PICTURE OF THE STEERING MODULE AS YOU CAN SEE IT ATTACHED. OTHER OWNERS HAVE REPORTED THE SAME PROBLEM. PLEASE SEE PICTURE OF INSTALLED AND NEW MODULE

DRIVING ON A FOUR-LANE STREET (TWO LANES ON EACH SIDE) WITH MY TWO KIDS. THE 2014 C250 HAD A MALFUNCTION WITH THE ELECTRIC STEERING: AUTOMATICALLY JERKING THE CAR TO THE RIGHT. I LOST CONTROL OF THE CAR AND HIT THE CURB. IT FELT LIKE WE WENT AIRBORNE. I TURNED THE STEERING WHEEL TO THE LEFT TO TRY TO STABILIZE THE CAR, QUICKLY REALIZING THERE WAS TRUCK TO THE LEFT I TURNED THE STEERING WHEEL BACK TO THE RIGHT TO AVOID HITTING THE TRUCK. THIS CAUSED ME TO HIT THE CURB AGAIN. IT ALL HAPPENED SO FAST IT WAS HARD TO STABILIZE THE CAR. MERCEDES-BENZ (EXPRESSED AS MBUSA) HAD MY CAR FOR OVER A MONTH. IN THEIR INCIDENT QUESTIONNAIRE THEY ASKED TO GRANT PERMISSION TO IMAGE THE DATA CONTAINED IN THE VEHICLE'S EVENT DATA RECORDER (EDR). I SENT THE QUESTIONNAIRE TO MY INSURANCE, AND WE DIDN'T NOT GRANT MBUSA PERMISSION AS THE LESSEE. MBUSA BROKE THE LAW AND WENT WITHOUT MY PERMISSION AND IMAGED THE DATA. THAN CAME BACK AND STATED THAT THEY WOULD NOT COVER THE DAMAGE, AS THE EDR STATED THAT I HIT THE CURB. MBUSA EXPRESSED THAT I WOULD HAVE TO PAY OUT OF POCKET FOR THEIR MALFUNCTION. I ASKED FOR A COPY OF THE RECORDED CONVERSATION AND I WANT THE REPORT. IT WAS EXPRESSED BY MBUSA THAT I WOULD HAVE TO GET A COURT SUBPOENA FOR THEM TO GIVE ME THE INFORMATION. I CALLED A ATTORNEY AND THIS IS AGAINST THE LAW; AND IS ALL TACTICS/STRATEGIES ON MBUSA PART TO NOT TAKE RESPONSIBILITY BECAUSE THEY WOULD BY LAW HAVE TO REPORT IT TO NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA). ALL I WANTED WAS TO KEEP MY FAMILY SAFE, AND FOR MBUSA TO TAKE THE CAR BACK AS IT WAS AROUND 3 MONTHS OLD WHEN THE ACCIDENT ACCUSED. IF I FIGHT THIS: JUST TO GET SOMEONE TO REVIEW THE EDR WILL COST AROUND $10,000. GREAT BUSINESS STRATEGY MBUSA IN KEEPING YOUR CUSTOMERS SAFE UNTIL SOMEONE DIES BECAUSE OF YOUR LACK OF HUMILITY! *TR
