“My instrument control panel backlighting experienced an electrical malfunction resulting in the failure to illuminate the gauges. The condition was diagnosed by my independent mechanic on 06/06/16. In doing so he informed me of recall campaign number 06v-028. I was told that the remedy is for the manufacturer to replace the cluster module free of charge and that I would need to call mercedes benz corporate to schedule a replacement. I called mercedes and spoke with eric at ext 7806 without any satisfaction at all. …”
NHTSA complaint #10874041, filed 2016-06, 90 miles“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. …”
NHTSA complaint #10534935, filed 2013-08, 29,066 miles“This vehicle often drops lower, while in motion. This is hazardous! I have had this airmatic air suspension system repaired three times on this vehicle within the last three years, and it appears this is one problem that mercedes benz refuses to correct. In my last S430, I had the same issue, and had to pay huge amounts to fix the problems. I feel no one is doing anything to get mercedes benz to fix this ongoing safety issue. I will like NHTSA to get mercedes benz to take responsibility for these ongoing defects.”
