What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There were several warning lights illuminated after the failure occurred. The vehicle as taken to a dealer where a diagnostic was performed; however, the cause of the failure was undetermined based on the failure codes provided by the diagnostic. The failure later recurred while the contact was driving 50 mph.
While attempting to exit the highway in rainy conditions, the steering wheel locked and could not be moved. She was driving less than 25 mph at the time of the failure. The vehicle spun out of control and crashed into the median. The vehicle was destroyed. There were no injuries.
Then one day I was traveling at near 70 mph in the passing lane of an interstate highway when the front driver brake locked up and brake tire smoke billowed from my vehicle which caused traffic behind me to swerve and brake behind and on the side of me.
Vehicle's front wheel brakes by itself while driving and the eps warning light comes on afterwards. Extremely dangerous in highway driving. Had the brakes checked, but nothing wrong. Online complaints suggests a failure in yaw rate sensor.
The all activity module (aam) does not function properly to which neither side mirrors can be adjusted because the windows no go up and down or longer operate. Then the door locks no longer functions and various other components rely solely off of this middle instrument cluster.
The contact also stated that the door lock on the drivers side door, locked and unlock several times when the fobik was utilized to lock the door. The contact stated that the vehicle had to be locked manually. The failure recurred each time the fobik or door lock was depressed.
There is an active recall for the all activity module on 2001 m class vehicles. There is an extensive amount of data that owners from the release of the mercedes benz ml430 have had problems identical to those in the active recall. When I call mercedes, they say my car is not impacted.
Tl* the contact owns a 2001 mercedes benz ml430. The contact stated that while driving 70 mph, the vehicle shook violently and made a loud sound. The vehicle was taken to the dealer. The technician diagnosed that the switch brake light and the air mass sensor were defective and needed to be replaced.
