Throughout the year, the car had many issues, the blind spot sensors and glass sensors didn't work, and it constantly showed that the stop/start system wasn't working. Twice, the car turned off by itself at a stoplight. Since everything is controlled through the car's large monitor, including the navigation, air conditioning, and all other functions, the monitor frequently shut off and it was necessary to turn it off and on again, or wait until the next day for it to work again. The scariest incident happened during a heavy rainstorm. I was dri…

Within the first week of ownership (delivery on 1/15/24), the car's parking and/or front collision sensors started malfunctioning on a regular basis. The sensors repeatedly gave off false alerts when the car would approach intersections even though no obstacles were in front of, or behind, the car. The false alerts were quite startling and they consisted of loud alarms and warning images in both the driver's display and the car's heads up display. The repeated false alarms posed a significant safety hazard because they initially caused me to…

If my sunshade cover had not been on, the glass would have fallen on me while operating my vehicle. This is not only dangerous but unacceptable.

Mercedes did not make me aware of the class action lawsuit they have with the panoramic sunroofs, and I feel that was neglectful on their part.

At approximately 26,500 miles of use, the check engine light came on in my Mercedes Benz C300.

Being that this seems to be a common malfunction with the C300, I believe that it should be considered as a recall issue. I don't know what could have h…

EXHAUST WAS COMING INTO THE CAR FOR MONTH. WHEN I STARTED THE CAR TO LET IT WARM UP IN WINTER MONTHS, I WOULD GET IN AND WONDER WHY I SMELLED GAS OR FUMES. FIGURED IT WAS FROM SITTING. NO DASHBOARD LIGHTS CAME ON, NO C02 SENSORS IF THERE ARE ANY, NOTHING CAME ON IN THE INTERIOR TO WARN ME THERE WAS AN INSANE. ONE PERSON TOLD ME THE PART WAS 'DEFECTIVE' ANOTHER PERSON TOLD MY BOYFRIEND THE PART WAS 'SPLIT MOST LIKELY FROM ROAD CONDITIONS' - THIS PUT MY LIFE AND MY 10 YEAR OLD'S LIFE AT RISK. IT REALLY NEEDS TO BE CHECKED OUT BECAUSE THE C300 COU…

MB USA extended the warranty coverage on the low pressure fuel hoses that connects to the high pressure fuel pump. The reason is "under certain cold ambient conditions during a cold start of the engine, the low pressure fuel hose at that connection may experience slight fuel weeping". MB USA, however, ruled out a safety risk. NHTSA needs to investigate it. If MB USA found the fuel pressure line is defective, they needed to do a recall. I believe it must be a recall as fuel leaks is not only a safety risk but also a serious health hazard to the …

THE 2017 MERCEDES-BENZ C300 VEHICLE SUFFERED A COMPLETE LOSS OF POWER/ELECTRICS WHILE IN MOTION AT SPEED AND IN TRAFFIC, CAUSING THE VEHICLE TO UNEXPECTEDLY STOP ON TWO SEPARATE OCCASIONS. THE LOSS OF ALL ELECTRICAL SUPPLY LEAVES THE VEHICLE IMMOBILE, WITHOUT WARNING INDICATORS AND CANNOT BE MOVED. THE FIRST INCIDENT WAS AROUND 5PM IN A BUSY ROAD JUNCTION IN THE DARK, WITH LIMITED LIGHTING. AS THE VEHICLE IS BLACK COLORED IT IT IS DIFFICULT TO SEE IN THESE CIRCUMSTANCES. THE SECOND INCIDENT WAS AT ANOTHER BUSY ROAD JUNCTION IN HEAVY TRAFFIC, AT…

WHEN THE CAR IS IN THE A FEATURE, WHERE IT TURNS ON AND OFF WHEN NOT IN MOTION, IT GETS STUCK IN THAT MODE AS IF A MAGNET IS HOLDING IT IN THAT POSITION. IT WILL NOT MOVE, IT STALLS. I TURN IT OFF AND TURN IT BACK ON AND SOMETIMES IT STILL WILL NOT MOVE, SOMETIMES, IT WILL NOT TURN BACK ON. THIS HAS HAPPENED ON SEVERAL DIFFERENT OCCASIONS. ONCE, I PULLED TO THE SIDE OF MY MAILBOX TO PICK UP MAIL, AND ANOTHER OCCASION I PULLED INTO MY GARAGE, AND IT STOPPED, AND WOULD NOT TURN ON. THIS IS VERY DANGEROUS, I WOULD HATE TO BE IN TRAFFIC, RAILWAY CR…

My car leaked oil very fast while me & my wife were on a trip and it stopped on the highway and engine was stalling and misfiring due to a manufacture defect that is common with this model so it did put us in a very dangerous & risky situation. Now after i paid $1,740 the dealer is saying that my car needs a new engine due to cracked piston in cylinder 1 that damaged the engine which is a common problem with this model around the 50k miles.
