Radiator started leaking in <3000 miles of driving the brand new GLE 580 Mercedes Benz. Twice I got errors in the car that stated check coolant level I could hear liquid moving in the front of the car when I parked it. Once while driving, the AC totally stopped working and on the entire drive, I couldn't feel the cool air. I also got 48V battery issue during this drive. I called the dealer and they said not to worry and that they will top off coolant. A few weeks later, I got another error and this time I took the car in and the dealer said that the radiator was impact by an "unidentified debris", had developed a leak and coolant was leaking. They refused to cover this under warranty and I had to pay out of pocket despite multiple requests to cover under warranty. This was a brand new car, no accident, this happened under normal driving conditions. The dealer and the manufacturer have failed to provide any documentation or engineering review. I believe this was a problem that existed in the vehicle prior to my purchase, i was sold a defective vehicle and Mercedes Benz didn't have proper protection in place for the radiator. I request NHTSA to do a thorough review.
