What 2014 Mercedes-Benz ML550 owners say
Most recent owner complaints, unedited.
The turn indicators stop working suddenly and randomly giving inaccurate/false indication to the driver of the vehicle that indicators are turned on and no indication of turn signal to the other drivers that can be hazardous especially at the 4 way stop signs where other drivers are assuming that vehicle is going straight where as the vehicle is intending to turn left but it is doing it without the indicator due to sudden failure of turn signal indicators and during lane changing. The hazard warning continues to work just fine and the turn indicator functions return to normal after turning the ignition off and back on. The occurrence of turn indicator failure is quiet often and has no set pattern.
Right passenger turbo failed after 50,000 miles several thousand dollars to fix
