Mercedes-Benz C-Class Change Vehicle

"MERCEDES-BENZ backordered a part to solve the problem. Still waiting for it. In the meantime most items work again"

"on occasion the center console display freezes when transitioning from reverse to forward. Usually the display will reboot itself after 30 sec or so and will work normally thereafter"

"Display froze, then flashed, then the COMAND system rebooted, again and again. This disables the rear camera, radio, everything. I was told that the issue was that the GPS had to be updated, which was repaired under warranty. Fortunately no problems since"

"SEE PREVIOUS ANWER"

"The screen is black not displaying anything"

"Already addressed in that display screen was replaced under warranty."

"The Comand system evidently has its own dedicated battery. That battery failed twice in the first four months of ownership, leaving the screen black until battery could be installed"

"sirius upgrade caused failure of the infotainment system for 6 weeks"

"The GPS was not tracking location. The dealer had to adjust or re-plug GPS antenna"

"Traffic info does not work"

"Was part of Command system previosly described"

"When I needed it most, it just stopped working. I got the message " maps currently off line.""

"Slow, slow, slow. Difficult to use. Data entry is good with touch pad. About 1/4 of attempted inputs for tech companies in silicon valley, system lacks information/address on buildings that have been constructed and completed for 7+ years"

"no voice control which means I have to take my eyes off the road to select the numbers to choose whom I want to call"

"The paired phone sporadically cuts out, making the in-vehicle Bluetooth useless"

"Sometimes it unpairs. Pairing is not intuitive. It takes a while to pair again, or it just comes back by itself, but not fun when driving."

"My phone often does not pair when I enter the car, resulting in missed calls. I re-pair it, but it often disconnects again."

"Radio did not work at all.It took 7 weeks to address the problem.We did have a loner for thje full length of time."

"SIRIUS BLAMED MERCEDES.....MERCEDES BLAMED SIRIUS....DISPLAY WENT OFF, REAR CAMERA AND BLUETOOTH DID NOT WORK.....RADIO DID NOT WORK......SIRIUS WOULD NOT CHANGE CHANNELS.....A THREE HOUR SOFTWARE RE-BOOT WORKED"

"It started with a message, 'Device Unavailable' on the infotain screen, Then after a while new message read, 'Please Wait', as if it was rebooting. All this time the radio, CD, and other devices are non-working. I took the car to the dealer and was told it was a known problem for this year C-class. They said a fix was available, but cause other problems if I have Sirius. Since I do not have a Sirius subcription, they reloaded the software that manages the radio, CD and ther devices. Problem was solved after that."

"This is usually addressed by the dealer when the car is in for recall or other service."

"buzzing and vibration during phone USge"

"It just doesn't recognize the commands. Wrong phone numbers chosen and dialed w/o verification, trying to find a location and it brings up a phone number. The voice recognition is terrible"

"Passenger seat belt buckle rattles when passenger is not htere Dash rattle under cold temperature"

"Brakes make very loud noise when in reverse. Knocking under car when driving, major noice from passenger window"

"I can only say that six months ago, a rattling sound began in the engine -- somewhere. Recently, Mercedes has put out a recall on all 2015 C300 models. I have to wait for the appropriate parts to become available before the recall repairs can be conducted"

"Belt idler pulley had to be replaced"

"The windows all squeak in the weather stripping when they are fully raised. The dealer has attempted three repair attempts yet the problem reoccurred with a day"

"Dash squeaks. Dealer tried to fix in 3 separate occasions and was unable to fix"

"Sudden onset of noises in the front end, driver's side. Happened after winter tires installed by dealership Turned out to be a wheel bearing problem"

"Sun roof was misaligned causing air noise at high speed. The problem was resolved by the dealer. No problems since."

"Wind noise is very apparent through the drivers side window...MB at this point has not fix for it. The noise is bad to the point that I will trade this car in next year if they don't come up with a fix"

"Sunroof supposedly warped, was replaced, now waiting on another part because of another sunroof wind problem. Probably same issue incorrectly treated the first time"

"Wind noise, driver's front door windshield. Took three trips to dealer to resolve. First to diagnose, second to install redesigned door frame which holds window, third to install redesigned window. Although dealer claims problem is resolved I sill here wind noise, but cannot isolate it for further action"

"Lights on door handles have failed (three of the four)"

"After a few months, the keyless entry stopped working, and I was unable to get in the car. It was a serious problem"

"Went to get into the car & neither key faub would work. Had to unlock it manually with the key and that set the alarm off, but we were able to stop the alarm"

"The problem has existed since I bought the car, new. It's a simple problem, the Keyless Go feature will not work at times, it will just not unlock the door, or any of the four doors. I must open the door manually by pushing a button on the fob. The car is not driven much so there is less opportunity to experience the issue. But I may experience it problem twice a month or go for many months with experiencing the issue. The dealership has looked at the problem many, many times and have been unable to fix the problem. How is it that after all this time they have no idea what causes it to not work. I have switched fobs with my wife (she has her own) but that didn't help. That seems to point a problem in the car itself. Nothing they have suggested works. It makes me wonder if the bothersome little problem has a very expensive solution that they don't want to pursue. I have kept logs as to time of day and location of the car when the problem occurred. I have provided many videos of the problem. Once the problem occurred within 2 hours of me getting to the dealership but they still found no evidence of a problem. I did not start keeping a log until 11/24/15. Since then I have documented the Keyless Go has failed work 21 times."

"Engine failed to start several times. Issue was fixed thru the dealership."

"For about a week after being serviced, the car kept warning me the tires were unbalanced. This was not the case, and it was pretty annoying. Had to bring the car in to have the gauge reset"

"The system has told me multiple times that more air pressure is needed in tires. One time it would not go off despite filling tires to correct pressure"

"The blind spot warning system keeps go on and off."
