2002 Mercedes-Benz C230 Problems

What owners report

Owners of the 2002 Mercedes-Benz C230 most often describe the engine stalling or shutting off while driving, sometimes at highway speed and sometimes in traffic, and often report that the dealer could not find a cause. Other recurring reports involve the battery draining with the car off, fire or burned wiring, steering lock or power steering failures, and a sunroof that does not open. Where mileage is recorded it spans from about 1,000 to 170,000 miles, and the stalls are reported both early and late in ownership.

   Engine stalls or shuts off while driving

   • 17 complaints (31%)
   • median 27,000 mi at 2.5 yrs old (9 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2001–2014

   Owners describe the engine stalling, shutting off, or losing power while driving, sometimes at highway speed and sometimes in traffic, and some say it restarted on its own after a few seconds. Some describe rough running, hesitation, or an engine that would not restart right away after it quit. Some say the dealer could not duplicate the problem or find a cause, and in a report a replaced fuel pump did not solve it. Where mileage is recorded it ranges from about 5,000 to 170,000 miles, with stalls described at highway speeds of about 60 to 85 mph as well as in traffic and at around 25 to 30 mph.

   What to check: Ask for repair records for stalling or engine shutdowns, and whether the fuel pump, fuel-pump wiring, or electrical connections were checked. On a test drive, check for rough idle or hesitation, and whether the engine restarts normally after a stop.

   2 excerpts from owner complaints in NHTSA records

   “After driving the car 90 miles on the highway, I was in local traffic about to make a left turn when the car stalled. I needed to restart the car before it would run briefly and then stall again. It kept stalling in traffic before I could pull over and have it towed in for service.”

   NHTSA complaint #10066391, filed 2004-04, 25,500 miles

   “Problems began at 10,000 miles aug 2002. Brought car to dealership 3 times since oct 2002 and dealership say their diagnostic tests show no problem and the stalling/rough idle is normal. They can't find any issues. Car stalls (depending on the weather)- worse on humid days, but everyday runs really rough upon start up. 50% of the time will completely stall. Other 50% if I gas the car, it runs really rough, but gets me out of my driveway. Car roughly switches to drive. Very little power when switching to drive and driving down the road. …”

   Electrical system

   Fire, melted wiring, or gas leak

   • 7 complaints (13%)
   • median 50,615 mi at 9.3 yrs old (4 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2002–2017

   Owners describe a vehicle fire, including a report that links it to the exhaust system area, and burned or melted wiring found after a stall or a failure to accelerate. Some describe gasoline pooling behind a seat, and a mechanic said a vehicle with a full tank could have caught fire after its fuel pump wiring burned. Where mileage is recorded it falls between about 12,000 and 99,000 miles, and the fire and wire damage reports are spread across the sample without a clear mileage pattern.

   What to check: Ask whether the car shows any burned wiring, melted connectors, or gasoline smell, and check the wiring near the fuel pump area. Ask whether any exhaust-area inspection or electrical repairs are documented in the service records.

   2 excerpts from owner complaints in NHTSA records

   “The consumer's vehicle ignited and caught fire due to contents next to vehicle igniting. The dealer, where the vehicle was towed to suggested the cause of the fire was due to fix a flat. The manufacturer representative and the fire department, determined the fire started due to the exhaust system which was directly under the area that burned.”

   NHTSA complaint #10027029, filed 2003-07, 22,000 miles

   “Vehicle fire with 2002 mercedes benz C230. Consumer noted four factual errors with the report provided to Mercedes-Benz corporate office. The consumer corrected the fact that there was damage beneath the carpet area and the idle test that was performed was irrelevant. The consumer stated excess heat caused or contributed to the fire in the trunk of the vehicle.”

   Electrical system

   Battery drains even when the car is off

   • 5 complaints (9%)
   • median 48,660 mi at 5.7 yrs old (4 state mileage, few)
   • filed 2006–2014

   Owners describe the battery draining even with the car switched off, sometimes within 24 to 48 hours, and some trace it to the power seat control modules. Some say the battery and alternator were replaced without stopping the drain, and some had to unplug the seats to keep the battery charged. A report describes an under-voltage message on the instrument cluster and a faulty voltage regulator, and the dealer quoted a high price to replace seat modules. Where mileage is recorded it falls between about 43,000 and 50,000 miles, and drains are described as happening even when the car is turned off.

   1 related service bulletin

   What to check: Ask whether the power seat control modules have been replaced or tested, and whether the battery draw has been measured with the car off. Ask for records of battery and alternator work, since a service bulletin notes that quiescent current can have several possible explanations, which can lead to parts being replaced unnecessarily.

   “My 2002 mercedes C230 kompressor keeps draining the battery. I have had the battery and the alternator replaced. No one, including the dealer can determine what is causing the drain. Online forums from mercedes outline that this is a regular issue that mercedes is aware of, but no recall has been issued.”

   NHTSA complaint #10197692, filed 2007-07, 43,000 miles

   “I own a 2002 mercedes benz C230, which has now had 2 severe issues with it. The first issue is the electrical system - the seat control modules go faulty and start draining the battery even when the car is turned off. If you have a battery drain, this is the likely culprit. I have replaced the seat control modules a total of 3 times. This is a common problem according to internet boards. The 2nd problem is that oil started to leak all over the wires. Again another common problem according to the internet boards.”

   Steering

   Steering lock or power steering failures

   • 6 complaints (11%)
   • median 27,000 mi at 4.0 yrs old (5 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2004–2019

   Owners describe a steering column lock that failed to engage while reversing at low speed, and a lever lock that slipped out of position during a turn after the warning light had gone off. Others describe an electric steering lock whose motor took hours to release the steering after the car was parked outside overnight. A separate report describes loss of power steering with noise and a front wheel that seemed to collapse like a flat, with tie rods later replaced. Where mileage is recorded it falls between about 20,000 and 163,000 miles, and the lock problems are described when parked, when reversing, and when turning.

   What to check: Test the steering lock and key operation on a test drive, including whether the warning light clears and the wheel stays locked after parking. Ask whether any electric steering lock recall work was completed on the VIN, and request records of any steering lock or power steering repair.

   2 excerpts from owner complaints in NHTSA records

   “After placing the vehicle in park, I pulled the steering wheel lever lock, (red warning light came on), and adjusted the height and depth of the steering wheel. I then pushed the steering wheel lever lock back in (red warning light disappeared). I started driving and while I was making a right on a curve the steering wheel slipped out of place and almost caused me to swerve into another lane. I pulled over attempted to reengage the steering wheel lock in several different positions, but it would not stay locked. …”

   NHTSA complaint #10470668, filed 2012-08, 115,000 miles

   “(1) normal driving in slow traffic; (2) noise and loss of power steering; feeling of collapse of right front like flat tire;continued to drive slowly; computer message-electric de-stabilizer not located; parked and called tow company; tow truck driver put car in reverse to enable towing; right wheel collapsed with tie rod projecting out; (3) a.

   Visibility (wipers, defrost, mirrors)

   Sunroof will not open or slide properly

   • 5 complaints (9%)
   • median 40,115 mi at 6.8 yrs old (2 state mileage, few)
   • filed 2002–2025

   Owners describe the sunroof or its shade not sliding or opening, and some report repairs that did not hold, with the roof repaired more than once. Some owners were quoted high repair costs, and a report describes a dealer requesting a fee to diagnose a sunroof problem after a sliding-roof recall had been issued. Where mileage is recorded it falls between about 1,000 and 55,000 miles, and the sunroof problems are described across early and mid-life mileage.

   Recall 22V954000Recall 24V874000

   What to check: Test the sunroof through its full open, close, and tilt range on a test drive. Ask whether the sunroof recall campaigns 22V954000 and 24V874000 were completed on the VIN, since the recall text concerns the glass panel not being properly secured.

   “I leased a mercedes benz C230 compressor for my daughter in 2001. The sun roof didn't slide back on the exterior or the interior. The dealer dismantled the sun roof. Mercedes refunded the first month's lease payment since she did not have use of the vehicle for the first month. After one year the sun roof needed additional repair. At 31,000 miles - the power steering failed the brakes failed and were replaced the differential broke the sun roof once again wasn't working... …”

   NHTSA complaint #10136535, filed 2005-09, 1,000 miles

   “The sun roof will not operate. Car has 55,000 miles on it, and I only used it occasionally. Being told that it wass over $2000 to repair. I googled this problem ,and found over 1000 entries of mercedes owners complaining of the same issue. Obviously, it was an inherrent problem with this C230. Could you do anything to help?”

   NHTSA complaint #10187410, filed 2007-04

Buying note. A buyer considering a 2002 C230 may want a pre-purchase inspection that checks engine restart and idle behavior, battery draw with the car off, wiring near the fuel pump, the steering lock, and the sunroof. Asking for records of engine, electrical, and sunroof repairs, and whether the sunroof recall work was completed, can help clarify the history.
