Mercedes-Benz C320 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.

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.

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.

Drive Train -- Verified

The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.

Mercedes-Benz C320 Reviews

awesome car use to have a mercedes c240, compared to the c240 the c320 has a good balance of power where as the c240 felt under powered. so far this car has been good to me no major problems so far at 98k. the only thing i wish was better on this car was the head unit which looks very dated and the exhaust which is too quite. of course now my goal is to get the c32 amg which has a great increase in hp about 130 to 150 hp more

I purchased my vehicle, the Sport Model with 18" with 207,000 miles and it is a gem. Put in new Air Filters (2) and increased mileage substantially. Rear shocks were bad but I replaced them. So far though, the blower will not go off. It blows full force even if the temperature is turned to '0'. I have replaced every part associated including the control center and still the problem exists. I'm going to change the cabin filters and hope that does it before taking it to Mercedes. Despite the problem with the heat, I love this vehicle.

to maintain your benz is more than a normal car that is unless you or someone you know can work on it. its more to take somewhere and have a shop do it. i had to replace my lower control arm shop said 1400. i got online found the part for 550 thats all it cost because i replaced it myself so it will cost more if you can not do the repair youself buy haynes book from autozone it will show you how to take the whole car apart and put back together good luck

I just bought this used car and not aware that the passenger front seat was not locked in place. Only the wiring is connected and its very unstable. Is there locking mechanism that I can buy to secure this seat?

150,000 kilomters 2003 C320 4 Matic Great Comfort Great Power Great Taction. You wan't to drive the ultimate machine, You have to expect a lil higher maintainance. Can't afford the mertz get a hyundai or a Kia. You'ell definatley save on maintenance. I love my Mertz...
