As a result, a short circuit may occur leading to an unexpected sudden loss of propulsion, increasing the risk of an accident. Moreover, strong electrical currents that may flow through the connection could cause an increase in temperature in the affected area, increasing the risk of fire.

The electrical systems drains the two batteries after the car sits idle for a few hours. If it can be started, many of the safety features are inoperable until the car is driven for 30 or 40 minutes.

No one had owned this car for more that a year. Service records indicate that previous owners had same issues. I purchased it in Nov of 2024 from Mercedes Benz of Clearwater, FL. I took it back and traded…

Safety issues also around front lift without cameras access. The vehicle was inspected at the Mercedes Benz Dealer and they fixed it, but after a day, the battery still isn't charging after…
