One problem related to electrical equipment has been reported for the 2002 Mercedes Benz C230. The most recently reported issues are listed below.
Initially the engine failed and the car lost power, in traffic, during a turn. The car would not restart immediately, and the electronic message center indicated there was "no malfunction" occurring. Upon arrival at my destination the engine failed after being placed in park, as I considered backing into the driveway. The dealer has inspected the car at least 4 times on 3 different days, and can offer no explanation for this defective performance.
