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. We have asked them to explain this seeming incoherence in their explanation, but they have not responded. Our conclusion is that the car malfunctioned. We still have the dashcam footage recorded during the incident, if that is needed.

Around 4pm 2/26/2026 my wife was driving southbound on I-65 around Middle River Bridge just north of Mobile AL. We were in the right lane when the car began to hydroplane; she immediately took her foot off of the accelerator and did not apply breaks. I was in the back seat due to a previous day surgery. The rear of the vehicle swayed back and forth a few times as the vehicle drifted. Then it was violently moved from one side of the lane to the other and eventually into a hard and distinct left hand 720 spin. We then collided into the concrete barrier next to the left hand lane. It was intense but a glancing blow mostly on the driver’s side. The spin ended with us pointing northbound in the left lane. Just as I thought the crash was over the car lunged in the forward direction like it was going to take off and quickly came to a stop. The weather was very hard rain and my wife was slowing for traffic ahead (which turned out to be another accident going up the General W.K. Wilson Jr. Bridge. Incredibly the car was still running and I was able to slowly drive to safety and not cause any further accidents. Later in the evening (screen shot shows 6:42pm) after reporting to my insurance I looked on Google maps to find the approximate area our crash occurred I could see another accident happened with a significant backup of traffic. I believe the lane assist and brake assist tried to correct the drifting and over corrected the vehicle into a spin. Lane assist in the 2024 Mercedes-Benz 450GLE is difficult to turn off and comes back on with restarting the ignition. I could not turn off Ln Assist and stay off when I purchased the vehicle, so believed it would operated like my 2022 Ford F-150 which stays off. Neither Cruise control, or Self drive was engaged. I believed lane assist could not be turned off and there are no warnings issued by Mercedes-Benz of the potential hazard although I now find Lane Assist can definitely be linked to hydroplaning accidents

I manually opened the power lift gate of my 2024 Mercedes-Benz GLE 450. While loading items into the rear of the SUV, the power lift gate closed autonomously and without warning, striking me on the right side of my face and neck. No hands-free gesture was made. Key fob was secured in my purse (in shopping cart) at a distance and was not activated.The lift gate did not detect my presence and did not stop or reverse. The impact resulted in localized swelling and tenderness to my face/jaw area.
