What 2024 Mercedes-Benz GLE450 owners say
Driver assistance
The Mercedes GLE450 was stopped at a red light. When the light turned green, the driver entered the intersection. The automatic braking system engaged without reason (there was open road ahead), bringing the car to a sudden standstill. The driver accelerated again, but this time the car went backwards into the car behind him. The driver had not shifted into reverse. So the car both slammed on the brakes, and switched the transmission into reverse, without driver input. Mercedes-Benz USA conducted an investigation and produced data showing that the car shifted into reverse while it was driving forward; they claimed this was driver error. However, the dealer (and our own experience) says it is impossible to shift the car into reverse when it is driving forward; the car must be stopped before it can shift into reverse. …
