I went to replace my low beam and high beam bulbs on the passenger side and found that the wiring for the low beam had 0 insulation on it and I installed the new high beam bulb and the wires starting arcing causing the car to turn off the high beams and start smoking from the headlight assembly.
- Suspension
Vehicle's body movement or damping motion while traveling on highway responds awkwardly. The vehicle has a waddle or a side to side motion instead of an up/down motion while traveling over the highway at 60 mph. My initial thoughts were to replace the vehicle's (air ride) struts. I chose to have Mercedes-Benz of Tyler analyze the vehicle ride problems which at that time involved the self -leveling adjustment (up/down) of the vehicle. Mercedes-Benz of Tyler determined and replaced the air compressor and valve block at 61,000 miles on March 16, 2023 to resolve the problem. Although no recalls were found for this vehicle, I've spoken with other owners who own S-Class vehicles and discovered…

- Electrical system
Struts and braking system have been unstable since I purchased the car. Wiring harness leaks oil and caused ecu to intermintinli turn off and on. Also the heat control timing caused car to over heat . Eventually I replaced the ecu 2 years ago at dealer . Mercedes has parts that are not safe to be in these operating conditions with such heat causeing wiring harness to short out and dealer said that and still put new ecu saying it was oil that damaged ecu. Mechanicly didnât make sense but now due to recall it all makes sense. Ecu was never programmed correctly causeing unsafe driving hazards .
