What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
Command control unit is faulty affecting navigation, voice control, bluetooth, and vehicle apps. Issue was present at the time of purchase and service technicians have been working on the issues for over a month. Issues are present when both stationary and driving. May affect other electrical and driving systems.
Driving down the highway at 70 MPH and '48v battery malfunction' warning goes off, along with a yellow check engine light. A few seconds later a 'coolant' error message pops up and a red check engine light comes on. Car looses power completely and I'm unable to accelerate at all. Call flashes a message of 'pull over and turn the engine off'. Fortunately no one was behind me and I was able to coast safely to the side of the highway before the car stalled completely.
I was travelling on highway with adaptive cruise control on. When near the exit, I press the off button for the cruise control. To my surprise, the car didn't slow down, and instead maintain the engine power to keep the car in set speed. I tried the other settings (off, cancel, speed down) option but nothing is responsive. Since I am on the off ramp already, I have to step on the brake (this does finally stop the cruise control) to slow down the car.
The car is equipped with power seats on the second row. My 2 year old son figured out how to use his right foot to move the seat forward and backward while traveling 65 MPH on I-95. This caused his tethered car seat to slightly pivot because the right seat rubbed against the middle seat. I called mb USA in georgia to report. They said there was no possible way to lock the control so kids can't move the seats.
