Mercedes-Benz C-Class

"Accelerator pedal replaced due to noise. Panoramic roof seals lubricated due to noise. Speaker loose in front passenger door created vibration at certain frequencies"

"dash vents snap and pop and squeek with any temperature adjustments"

"Two major sources of squeaks are steering and moon-roof"

"Squeeks from dashboard and door cards, over bumbs the car makes lots of noise from those areas, like the dash isn't properly aligned and components are rubbing against each other that shouldn't"

"Many interior plastic sounding rattles and vibrations caused by speakers. Dealer has been unable to resolve after multiple visits and says this is common."

"The car is noisy over small bumps. Sounds like plastic twisting or rubbing. It is kind of a crackling noise. Not what I expected for an expensive car."

"Squeaks and rattles have been a recurring problem. Multiple trips to the dealer havent fixed the problem."

"Noises emanating from dash"

"Air-conditioning motor has a very loud sound at full speed a loud whine and also the smell of oil often comes out of the blower motor."

"There is a constant wind noise in the driver's door window when the car exceeds 35 mph. Once again I expected better in such an expensive car."

"After the moon roof was reinstalled, I experienced wind noise. In a test drive with the shop foreman the dealer said it was coming from the driver's side window, not the moon roof."

"It did not work properly with Apple phones at first"

"Software reload fixed problem"

"Does not work, does not recognize voice. The system is so bad it should not be sold"

"In dash navigation not reliable. Ended up in field in NC."

"Voice command to find a well established business location rarely gave me the correct direction or information. The Acura TL I had previously was very accurate."

"It auto tunes the frequency constantly and the reception is poor."

"check engine light"

"Speakers make terrible rattling sound with specific reproducible tones. Dealer has replaced speakers but problem must be around speaker because issue hasn't been resolved"

"Front door speakers would buzz and vibrate. Front dash speaker would buzz in the tone range of the human voice. I got a tone generator on my iPhone to identify the tones with the biggest issues. It is very disappointing to have such issues on a premium sound system on an expensive car. This is the worst sound system I have had. Cars half the cost do not have this issue."

"Despite the fact I enunciate well, the commands seem to be unintelligible; therefore frustrating. If I ask for Columbus, OH it goes to Santa Barbara, CA. If I'm in Illinois and want to go to Naples, FL the device does not hear Florida and wants to send me to Noble, IL or whatever"

"Very poor voice control commands. I have a Mercury Mariner equipped with Ford's original Sync, which is substantially better than my Mercedes"

"At 39000 miles I had to replace the brake lining. Also, it is a challenge to make the car go when I step on the gas. It takes a couple seconds to make it go. I would never buy another MERCEDES-BENZ again."

"Pulsating and vibration noticed on descents. Worse at 60-70 mph descents in the mountains. Bought certified via MERCEDES-BENZ dealership and within 2000 miles of ownership, they replaced pads and rotors. Had driven 14000 miles, same vibration returned."

"The brake pads were worn out after about 32,000 miles. It cost almost $400 to replace them."

"At 28,000 miles I started to get pulsing in the brake pedal at highway causing speed. MERCEDES-BENZ dealer said rotors and pads needed to be replaced, cost was $700. At 38,000 miles it started doing it again. Took back to a different MERCEDES-BENZ dealer (I moved) and they replaced rotors and pads for free."

"The steering wheel shimmied when I braked at freeway speed. The dealer said it was rust on the rotors. The factory refused to cover it on warranty but the dealer paid for the replacement of the brake rotors and pads so it cost me nothing. I was irritated at the Mercedes-Benz factory, but appreciated the dealership coverage"

"The brakes began squeaking when I went in reverse. I was told that there was a problem , did not involve any safety issue. The problem has been resolved by Mercedes"

"I have complained about this issue for 15 months. Dealer has been unable to fix Brakes squeal when baking up."

"Problem persisted and dealership could not find the problem"
