2009 Mercedes-Benz C300 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2009 Mercedes-Benz C300

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.

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).

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.

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 t...

I bought my 2009 C300 Sport new and now at over 6 years and 66K Mi it's been a reliable and enjoyable car. I had a faulty xenon headlight, a few rattles, AC stink that requited a few cleanings, and a noisy belt tensioner fixed under warranty...pretty minor things and otherwise still on the original battery and brakes. It drives like new and I hope to keep it for at least another 6 years. The...
