Just as reported in consumer reports, electrical systems failed on this vehicle causing all safety systems (ie., brake assist, safety belts, air bags) to fail. The problem caused two accidents last year when the 4,400 lb. Vehicle could not stop. Other electrical systems are also failing. Further, the rear gate latch was not locking and the dealer never verbally told us when we picked up the vehicle from being serviced, nor did they ever ask if we wanted it fixed. We just found out about this. One would expect more from a Mercedes product. After the truck was "fixed" twice, we then paid to have it gone over ($300) and found the problem with the safety systems which had been noted as being fixed previously. It was a $100 stop switch. Meanwhile, we will pay higher insurance rates for the next three years. Mercedes usa should have recalled these vehicles for the electrical problems, but they just brushed it under the rug. I thought we were buying a quality product. I guess not.
