This vehicle on an ongoing basis is reporting false speed limits. It consistently abruptly drops the indicated speed limit from 70MPH on [XXX] northbound in Salt Lake City. the vehicle slows itself abruptly in traffic that is sometimes dense and traveling 70 to 80. An eventual rear end collision seems likely which could involve multiple vehicles. It intermittently presents the same risk in other locations with no as yet recognized associated variables such as the one location on [XXX]. Exact start and stop of the erroneous speed limit are not consistent. Sometimes brief and sometimes for a mile or more.

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.

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.

I own a 2022 Mercedes-Benz E350. The front glass roof panel located directly above the windshield developed a large crack while the vehicle was parked. The crack extends nearly the full length of the panel and includes areas where the glass has separated along the fracture. I am not aware of any collision, road debris, or object striking the vehicle before the damage was discovered. The damaged panel is available for inspection. I am concerned that if this type of failure were to occur while the vehicle is in motion, broken glass could fall into the passenger compartment or be shed onto the roadway, creating a potential safety hazard for the driver, passengers, and other motorists. The vehicle has been inspected by a Mercedes-Benz dealership, and the damage has been documented for repair. To my knowledge, there were no warning messages, alerts, or other symptoms before the crack appeared. The cause of the failure is unknown. I am aware of reports from other Mercedes-Benz owners describing similar cracking of roof glass panels. Based on those reports, I am concerned this may indicate a broader design or manufacturing issue and respectfully request that NHTSA investigate whether this represents a pattern affecting similar vehicles.
