I purchased a certified pre-owned 2004 Mercedes Benz S430-4matic in March 2007, after retiring. I also brought an extended warranty costing over $3000 dollars. I have returned this vehicle to a Mercedes Benz dealership for repairs over approximately 27 times since purchasing the vehicle. The problems include the electrical system (door locks); trunk lid lock, suspension system, tire pressure sensors, engine and engine cooling system (air conditioning system will only dispense cold air at 55 degrees and lower) and most recently the radio and navigation system are failing. Now that the warranties on the vehicle have expired the dealership will not repair the above problems under warranty. I filed a complaint with Mercedes Benz usa and I'm waiting for a decision regarding the repairs totaling over $4700.
