I keep getting coolant level low. I add coolant fluid into the tank and the warning message comes up again. I see no leaks under my vehicle so not sure if there’s a leak inside the tank itself or air leak somewhere but I’ve gotten that warning message about 10 or more times. Also as im driving the blind spot sensor just randomly goes off without a car or anything being next to me.

My 2020 GLE 350 first displayed a problem with left indicator on front left hand head lamp. I took an appointment with my Mercedes dealer for repair. Then it started showing all kinds of safety problems on the screen -like blind spot monitoring, collision warning etc not working. I parked it in my garage, shut off the engine, locked it and in a couple minutes, it started a blower like sound. I called Mercedes service center and described the problem. They sent a tow truck. While waiting for tow truck, the blower would automatically start every 3 to 4 minutes in a standing, switched off car which can be very dangerous. After diagnostics the authorized service center found the root cause to be a worn out seal which let condensation in the lamp assembly and the water entered in the electrical module. I have taken up the issue with Mercedes corporate. While they are investigating, I wanted to file this complaint so that if there are similar complaints in this model, it may be a manufacturing defect that needs a recall to fix the bad sealing

The main multimedia screen in the car has failed and is malfunctioning. Rear view parking camera only works some of the time. No access to temperature control. No access to navigation. No access to multimedia. The lack of functioning camera system has put myself and others at risk during parking and driving. This has been reported as a recall in the past (the federal safety agency 21V354, MBUSA Campaign 2021080009) and has been reportedly completed. My concern is that this repair/fix dis not sufficiently address the root of this issue and now the problem has returned.

When operated with driver assist and stop and go assist, the car, often slams the brakes for no reason in the middle of the highway. I have reported this problem multiple times to the dealership and the dealership has kept the car in for investigation multiple times sometimes for more than two weeks. They were able to replicate the problem, but they had absolutely no solution. It’s been a few years now and it keeps happening. This is a liability issue us cars behind me are at risk to collide.

While driving on the interstate in the right lane with adaptive cruise set at 70mph the cameras will occasionally read the off ramp/exit speed limit signs and brake hard to decelerate to the posted off ramp speed limit. This creates an opportunity for a rear end collision. Additionally, the adaptive cruise will “see” vegetation or guard rails on the opposite side of the road, while in a turn, and brake as if to avoid a collision when no hazard exists. Many instances of the two anomalies.

My 2020 GLE350 met with an accident on 1/20/2023. My wife was driving this vehicle on the freeway at about 40-50mph and she rear ended a Toyota Camry that was ahead of her. Mt complaint is two fold - The airbags did not deploy - The Active Brake Assist system failed to work The collision is a major one. You can see from the pictures. The body shop, an approved vendor for my insurance Geico, has prepared an estimate for $25,487. My vehicle has been in the body shop since the day of the accident. On 1/27/23, the estimate was prepared. I have to approve it and they will start the work anytime this week. This high repair cost is an indicator of a major collision. In such a major collision, I'd expect - Airbags should have deployed. The Camry's airbag did deploy, so should have ours. My wife suffered a strong whiplash. She has severe neck, shoulder, elbow pain and headaches. She is scheduled to undergo physical therapy. If the airbags deployed, these injuries could have been avoided. - The Active Brake Assist system should have been activated during the rear end collision. It should have detected and avoided the collision. However, it failed to deploy too. Few times when I back up, this safety feature has been very useful. It will identify moving objects like pedestrians, vehicle crossing and automatically apply the brakes and prevent potential collision. However, when we needed it most, it failed to save us. The automatic braking didn't happen. There were no visual or acoustic warnings prior to the collision. One of the main reasons I bought GLE350 was for this safety feature. I am so disappointed by this catastrophic failure and questioning whether I should drive this Mercedes anymore. Because of these safety failures, I really worry about driving this vehicle and bringing to the federal safety agency's attention. Please investigate this safety failure.

The Brakes Failed - At Mercedes Dealership for Over a Month My Wife could have been killed on the highway going 70MPH with no brakes The car was towed by Mercedes over a month ago and never returned. No one will talk to me. Mercedes will not speak with me. Nor have they contacted the dealer - Letter Enclosed No warning - Just brake failure. Prior to that we got a "Your cameras are not working message" a week prior and the car would warn you another car was there. But there was no car.
