In mid-trip as we were going down the highway went to change lanes and the turn signals were no longer functioning. No errors, no alerts, no warnings they just stopped working. After pulling over and turning off the vehicle and turning back on they work for a time then stop working again. After researching with other owners of these and similar model Mercedes Benz vehicles this is a prevalent and highly dangerous safety issue that many many others have experienced.

I was in drive mode and was looking to park the car on the open spot on the street. Had engaged the reverse gear and was attempting to get in the parallel parking spot. While i was doing that, suddenly the wheel locked up and car stopped with a jerk/jolt. Then came warning that the parking brake was not working (Remember I had not engaged the parking brake as I was in drive mode). The locked up wheel would not move and I had great difficulty in making the car safe in the cross traffic. The issue here is parking brake cannot engage by itself. That has nothing to do with the age of the car, it is like the wheel cannot come off just because the car is old. This could have easily happened while the car was in motion at a higher speed, in that case with 1 wheel locked, a car would spin out of control in a moving traffic causing major damage to other vehicles and myself. Mercedes's rep claimed it was a maintenance item. Parking brake engaging by itself is a maintenance item?? We should put a

In April 2023, while performing a rear brake service both right and left suspension springs were found with deteriorated suspension spring coating, corrosion and breakage of the coil springs. Suspension spring failure poses a safety hazard and risk of damage to other suspension components. It is unclear when exactly the springs broke but when the vehicle was inspected in Feb of 2022 there was no mention of spring breakage. The date of incident is the date I discovered the spring breaks. I only took a pic of the one spring but both were confirmed broken. MB dealership confirmed breakage. Communication with Mercedes Benz was not successful.

Engine stalled multiple times even though it has been serviced multiple times at multiple dealers.
I took my car in for a different repair and they found this issue as well. "Diagnostic - Oil leak (Visual): front covers leaking oil down front of engine." The leak was due to a crack in the sealing cap. My car 2015 Mercedes ML350 4Matic is in the recall for 2018070015 but my VIN number was not included in the recall although I am having the exact issues the recall covers. Recall 2018070015 "correct oil level as necessary and replace the reservoir sealing cap to prevent oil foam from leaking out."
