When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

WHEELS
When turning the steering to maximum wheel camber, the wheel rims roll over the sidewall of the OEM low-profile Pirelli tires, damaging the tires and causing bubbling in the sidewall. This happens at a negligible speed, such as exiting a parking space. This vehicle is 3+ years old with 15k miles. Low-profile tires appear to be incompatible with the steering design.

POWER TRAIN
Twice within a year a "48 voltage battery malfunction" warning appeared on my dashboard. Then a red warning light appears and I had about 30 seconds to find a safe place to pull over as loss of power causes deceleration of the vehicle . The cause, according to the diagnostic test performed by 2 different Mercedes dealerships, is that a software update is needed. A know of no situation where the machine crashes first then you're told to update its software. I am concerned that this will unexpectedly happen again and possibly on a road where pulling over to a shoulder may not be possible in the little time given before power failure.

STRUCTURE:BODY
An underbody splash shield (one of three, I believe), covering the transmission (the middle of the three) detached at highway speed and fell off the vehicle. This caused the leading edge of another shield to detach, which then, due to air flow, began dragging the highway. It was quite a noise; initially I thought it was a tire blow out. I quickly decelerated to try to move to an exit (it was urban highway with no shoulders), at lower speeds, the panel stopped dragging. There was no road debris involved in the event. The first panel simply detached (and was not recovered / recoverable due to the location) leading to the second. The initial mechanic replaced two bolts to secure the second panel. He said this is not uncommon on Mercedes Benz vehicles and seemingly knew exactly what was needed (I was expecting duct tape on a weekend morning). Later, after some discussion, the dealer (the car was under warranty; only 13,000 miles) replaced the missing panel as a "courtesy" but not under warranty (because they said I did not have the missing part).

ELECTRICAL SYSTEM
I was driving the car on a road I drive daily with my son in a child seat in the back row. The car inexplicably slammed on the brakes at full force, stopping in time to avoid driving over the shadow of a tree. Approximately thirty minutes later, there was a loud popping / explosion sound from inside the engine compartment, the car lost all power, coasted along for approximately 100 feet, and then restarted while coasting. This is the second time in under a year that the car has experienced a major electrical system malfunction.

WHEELS
Two rectangular blocks descend from the plastic shield under the front bumper. These blocks have a squared-off back. These blocks descend for about an inch, and are located a few inches in front of the front edge of the tires. In normal use, when the car is parked in a parking space the front tires roll forward to rest against the parking stop block, those descending vents hook onto parking stop blocks or curbing. When the vehicle is backed away from the parking space, the front shield can be torn away from its mounting points. The damaged, loose shield could strike and damage the front tires, or it could impact and damage the front brake lines, or it could obstruct the suspension, or the steering components.

I was driving last week on a Dallas street. The public works people had place a 1 inch this rectangular steel cover over, presumably, a hole. The car slammed on the brakes, with a red light appearing on the instrument panel. Had a car been behind me, it would have read ended me. I spoke with Mercedes. They tell me that Mercedes has no ability to turn off the automatic breaking feature, and I should go [XXX] myself.
