The 2011 Mercedes S400 Hybrid has faced several significant recalls. An NHTSA bulletin 12V557000 was issued for S-models due to a problem with the fuel filter flanges, which can crack under high temperatures or extreme heat. This issue is due to the design of the flange, which causes oil leaks and a risk of fire or vehicle combustion if exposed to an ignition source. More than 5,000 vehicles were impacted, requiring the fuel filter to be replaced at local dealerships at no cost. The S400 was also recalled for a faulty power electronics control module and charging system errors that can result in a no-start condition due to low voltage.
If the electric battery converter fails, a replacement will cost around $10,000. It may not be worth investing in this car if it has more than 80,000 miles on it.
While the 2011 Mercedes S400 doesn't have any specific problems, considering its age, there's a good chance that issues could arise with the engine or transmission due to wear and tear. Rust or corrosion may have developed on the metal components over time. It's also important to inspect the brake and fluid lines for signs of dry rot and leaks. Regular maintenance like replacing brake pads and checking tire condition is recommended. Additionally, checking for any deterioration in the oil lines and pump, cracks in the oil pan, as well as inspecting for faulty wires or blown fuses that could lead to electrical issues throughout the car is essential.
My issue is with starting the vehicle, and it is connected to the Hybrid system.
