What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
MBUSA [ref] - 2013 MB AMG ML63 Engine Signed - my vehicle is not drivable due to random sudden engine stalling at highway speeds, electronic failures, gear-shifting lockouts, hazard alert/radar failures, and distronic system crashes.
The contact stated that the vehicle was experiencing front suspension, coolant, and oil leak failures. The contact stated that the front suspension unexpectedly lowered while the vehicle was parked or while driving. The message "Active Curve System Malfunction" was displayed.
An âEngine Overheat â Shut Off Engineâ warning appeared on the instrument cluster and steam began emitting from the engine compartment. Because the failure occurred while traveling at highway speed, the driver was forced to execute an emergency maneuver across traffic lanes in order to reach the shoulder safely.
Vehicle failed oil consumption test. Vehicle has been leaking and/or losing oil for months despite the issue being alleged fixed under NHTSA recall 18V272. The issue is ongoing and Mercedes Jacksonville is claiming the oil leak is from another issue not covered under warranty or recall order.
The contact stated while driving at an undisclosed speed, the check engine warning light illuminated on the instrument panel with the "Low Hydraulic Fluid" message displayed. After a visual inspection of the engine compartment, the contact observed hydraulic fluid covering the engine.
Somewhere in South Carolina, a message appeared on my display that said the blind spot assistant was disabled. Soon thereafter, my turn signals quit functioning. At first chance, I pulled over and turned the car off hoping it was some kind of computer reset. That worked but only for an hour or so.
