POWER TRAIN, ENGINE, VEHICLE SPEED CONTROL
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!

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
I was driving on the highway my car sort of hesitated for a brief second then continued on as if nothing about one mile later my car began to slow down while I was in traffic so asap I pulled over at this point I could only go about 40 miles per hour which was very terrifying at that time it came a complete stop. After restarting the car 3-4 times it stayed running I continue home which was about 12 miles from my current location. For the next few days I did not go any where. I then had an appointment to have the 80,000 mile maintenance I mentioned the problem I was then told I need a throttle body replacement costing more than $2000 that I can not afford. At that time I started researching my own problem. My relative who works on 18 wheel truck for a living, . that perhaps it just may need cleaning rather than replacement . Also per my research this happens quite often with this model it also stated that Mercedes C250 was the worst Mercedes of that year many many owners have had this problem. The yellow ESP light come on saying it is off also my hold brake no longer works. It work at my prior dealer appointment it while going to appointment afterwards it did not work since over 9 years seldom used I wasn't concerned thus that is the message that appears when car fails Mercedes wants me to pay I believe $2000 problem not needed

FUEL/PROPULSION SYSTEM
I bought my 2014 C250 back in 2017 with 17K miles and currently has 58,570 miles. The issue is with fast acceleration from a stop or slow moving. When trying to accelerate to merge with traffic after a few seconds the vehicle goes into limp mode and the check engine light comes on. In limp mode I am only able to accelerate very slowly and this is a major concern for my safety. This has been and ongoing issue over the past few years and I have learned to reset it temporarily (around 10 times) with a YouTube fix. I recently found out that there was a recall for the high pressure fuels pump on some C250 models but mine was never included. I also found out that the recall time limit has expired. Please investigate and expand the recall along with the time limit so my vehicle will be included.

AIR BAGS, ELECTRICAL SYSTEM, STEERING
While I was driving my car the driver side airbag abruptly deployed. The airbag inadvertently deployed; the car did not crash into anything to cause the airbag to deploy. When the airbag erupted it caused injury to my head, face, hand, arm and wrist. I believe the airbag is defective because I have lacerations on my face possibly due to sharp objects ejecting from the airbag and the impact as well as excessive smoke and fumes emitted after the fact. I believe there might be a manufacturing defect in the airbag because it seemed as if it exploded with excessive force causing harm to myself as well as inadvertent eruption. There have been some recalls issued on the motor vehicle and I did take the vehicle to the Mercedes car dealership to get all of the recalls repaired, however this incident occurred after the repairs were made at the dealership.

STRUCTURE:BODY:DOOR:HANDLE:INTERIOR
The driver's side interior door handle became disengaged as I was trying to open the door so I was momentarily trapped inside. If I had been in a situation where I had been in an accident and needed to get out quickly, or the car had been on fire, or I was stalled on the train tracks, this could have been a serious incident. When I googled this, it sounds like this is a very common occurrence in Mercedes. There was no warning that this was going to occur - everything seemed secure before this happened. I have taken it to a service center for a very expensive repair as they have to remove the door panel, replace/reattach the part and put the door panel back.

AIR BAGS
The passenger airbag was replaced under the Takata recall. Recently the airbag indicator light came on for the driver airbag. We have been notified by the dealership that this airbag needs replaced. They provided an estimate of $2,652.29. We reached out to Mercedes due to this being a safety issue and also due to the fact that the passenger airbag was replaced under a recall. They are unwilling to assist. It is illogical that just the passenger airbag is faulty in the recall but that the driver's airbag is fine as they came from the same manufacturer and installed when the vehicle was built. We are concerned about either deploying on its own or if it will deploy in an accident.

STRUCTURE:BODY
1. the component that failed was the front stationary sunroof panel, and what failed on it was the adhesive which leads to it leaking water, and the potential of even falling off while driving 2. it could lead to falling off on the highway which could lead to damages to it or other vehicles around it 3. Unknown 4. Yes it was inspected at a nearby dealer ship in which they stated that the glue was failing on that part of the car and would need to be replaced 5. No warnings for this issue, i was only able to notice it because when it rains now if not under cover that part of the car will allow water to leak into the vehicles inside There was a recall campain in which the number is 2021070010 and it included 2014-2020 mercedes C class which my vehicle matches said description but when i have tried to get this issue resolved but my vehicles vin number was not apart of this recall as it shows across multiple sources

VISIBILITY/WIPER
I prchased used with no visible damage to the windshield. In the inclement weather for no apparent reason my windshield began to crack as I was driving the vehicle. I pulled over as soon as I could. The crack stoped and I called the Mercedes Benz manufacture to no avail. I decided to research to see if this is common and the article says, "that the 2014 Mercedes Benz" windshields are known to crack in extrem cold and hot conditions. The windshield has continued to spider and crack in different direction. I feel threathened at this point and featful for my life that this will implode in my face while driving. I did in good faith reach out to someone.

The driver's side door handle broke impossible to open door from inside if there was an accident. I have been told that this is a common problem with my car, and that it cost 1600.00 to replace repair at the dealer. This is such a common problem that there are after market kits to repair the broken handle for 20.00, but including labor the repair is $500.00.

POWER TRAIN
I was driving my vehicle when the transmission started shifting erratically. The shifts were not smooth but hard and the car was shuddering. Yes the vehicle is available for inspection. My safety and the safety of others were at risk due to the erratic behavior of the vehicle and how it affected my ability to focus on driving safely. Yes my vehicle has been inspected by the manufacturer and the problem has been reproduced by my local Mercedes Benz dealer. There were no warning lamps or messages prior to the failure. After a few weeks of driving I saw a “low coolant” warning appear, this turned out to indicate that the radiator had leaked coolant into the transmission which damaged the internal transmission components and torque converter.

STEERING
Mercedes has a convenience easy enter/exit feature that lifts the steering and slides the driver's seat back for easy exit and restores the seat and steering when the driver sits down and places the key in the ignition. The safety issue is the steering often gets locked in the up position and doesn't lower, making it unsafe to drive the car. This is happened 5 times since I bought the car. I had to drive home with the steering wheel locked above the dashboard. The car has been towed to the dealership 4 times under warranty and now I have to get it towed myself. There are approximately 54000 miles on the car.
