Mercedes-Benz C300 Problems

Drive Train -- Verified

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Brakes -- Verified

Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).

Brakes -- Verified

It is not uncommon to encounter premature failure of the anti-lock brake system (ABS) modulator assembly due to dirty brake fluid. Our technicians recommend flushing the brake fluid every two years in order to help prevent this problem.

Mercedes-Benz C300 Reviews

Love the car. 52,000 miles and rear brakes are just needing replacement. Minor issues with maintenance warning message that was solved by replacing sensor in driver's seat belt buckle, otherwise never a problem. Only complaint to this "luxury sports" vehicle is wishing for a bit more than stock 228 HP. Am trading for CPO 2103 to solve that issue.

Wish I had bought a Ford. This thing is never in working order. Never out of the shop. Now having check engine lights constantly. Dealership charges $121.00 to do what O'Reilly's does for free. Every day I pray a Ford drops in my lap.

I bought my 2009 Mercedes C300 5 months ago. It only had 26,700 miles on it so I thought I was getting a practically new car...I was wrong! This car has so many problems...big and small...the first week that I had it I noticed oil leaking...had to get the bearings replaced in the motor. It shakes breifly at startup. The clear coat paint looks like it's coming off in a few places. The drivers door will not lock. The interior of this car looks cheap. I wish that I would have kept the Nissan Altima that I traded in...much nicer car.

This is our first 2009 c300, we will have a mercedes from now on,, i think this is one of,, if not the best car in the market. We bought ours through Car-Max and it checks out.Thank you Mercedes

This is my first Mercedes car (2009 C300)that I've purchased. I traded a 2001 BMW330i that I had for approximately 10 years. I fell in love with the car. It looks great and rides great. Unfortunately....I have been dealing with this annoying waxy or crayons smell which the dealer is having a difficult time in eliminating. They've treated the evaporator coil, changed the cabin filter, scrubbed the carpets and performed an ionization on the interior. The original smell is not as strong but is still there and very annoying.
