2003 Mercedes-Benz C240 Problems

Heating & Air Conditioning -- Verified

A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

Engine -- Verified

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Miscellaneous -- Verified

Inside grab handles, the upholstery on the center console cover, and door trim panels can delaminate. Most commonly replacement of the affected part is necessary.

Suspension & Steering -- Verified

The sway bar end link joints may wear and cause a knocking noise over bumps. Loose or warn links should be replaced to correct this type of noise.

Electrical & Lights -- Verified

A dead battery can be caused by a faulty seat control module that does not properly shut down.  Spilling liquids on the front seats can cause these modules to fail.

I agree, what a piece of crap. Oil changes in Canada cost $350. Tied up for 4 Hrs.
The dealers screw you every chance they get, take the fun out of owning the car.
Over priced parts, they recommend oil change every 5000 km, claiming cold and heat????? Had car in for service, came back with close to $3,000 in recommended service. Went to a mechanic, and trimmed it to $1000 including parts. Recently had car quit, dealer claims crank censor, then came back with battery & alternator
I can't wait to dump this piece of crap!!!!!!

I own a 2003 C240 Mercedes. I have owned it for about 3 years. I have owned a Corvette, Lexus, BMW M3, Escalade, and my Mercedes. From my personal experience Mercedes is the biggest piece of ???? car ever made. It sucks. They have tons of electrical issues and is a nightmare dealing with all the faulty sensors and errors. I will never ever own another Mercedes and I think its funny how so many self proclaimed Mercedes experts think they have the simple answer to solve the problems. For the most part none of them work. Read the posts about people spending thousands to end up with the same problem never resolved. No one can figure these cars out, not even the dealerships. Mercedes is a true piece of ???? automobile. Got problems get rid of your Mercedes asap. I will never own one again if I can even get rid of this piece

Bought 2003 C240 as Certified pre-owned with 43k miles. Immediate issues (after 50k) AND ongoing problems. Examples - rear window and antenae had to be replaced; both front door internal handles broken; ash tray and cigarette lighter broken (non-smoker); replaced at least 10 brake lamps or turn bulbs; replaced turn signal arm; rear door overhead handle broken, ETC. Horrible quality, overpriced service. Worst vehicle I have ever owned.

I have 2003 mercedes c 240. i bought it used about six years ago and never had any problems out of it. just general maintence and crank sensor recently went out but overall its been a good car and i cant complain
