Unexpected Acceleration
My 2022 GLE 350 unexpectedly accelerates on its own. This happens at low speed right after braking and turning a corner, like pulling into a parking lot ..immediately after taking my foot off the brake after/during turning, suddenly the car takes off, like the distronic is kicking in, I have to quickly hit the brakes. It doesn't do it all the time but it's done it a dozen times since last September. I haven't taken it to the dealer yet as I thought maybe I was accidentally stepping on the accelerator after turning. I've been paying attention to when it's happening and it's definitely doing it on it's own. Anyone else have this issue?
thanks!
thanks!

I had issues with my GLE’s Distronic, that would do unexpected, dangerous things. You should definitely report it to the NHTSA, but good luck trying to get it fixed.

First thing to always check in the situation is the floor mat to make sure it’s not making any contact with the Accelerator pedal. Make sure the retainers are there and working.

Definitely report it to the NHTSA. I was already interviewed by an investigator about unintended Distronic movements on my GLE. Also, some people are hesitant to post about their issues, but there are others as well that I found here. One even reached out to on me and left me a message on my profile.
Mercedes will plead ignorance and say there’s nothing wrong. That’s a fact.
Good luck, though.

Eqs 580
My parents EQS 580 accelerated when breaking, jumped two curbs until finally crashing. Sensors didn’t work to detect things around the car and air bag never deployed either. I believe something is wrong with the car, not that the gas was pressed instead of the brake.

Unintended Acceleration And Turning with loss of braking
My 2022 GLE 350 unexpectedly accelerates on its own.

My wife was pulling into a parking spot and the car started accelerating and turning to the right. It did not respond to the brakes at all. It hit a brick wall at an angle and deflected off of it into three other cars.
I would estimate that she may have been traveling at 5 mph entering the parking spot and judging by the amount of damage, I think it accelerated to perhaps 30 mph by the time it hit the other cars.
Mercedes is currently investigating, but is not providing us yet any information as to what caused this.
Has anyone else experienced this?

We have a GLC 300 4Matic SUV that is just less than a year old.

That is surprising because for the speed adaptation thing only have instances of suddenly braking when the speed changes not suddenly accelerate. Did the dealership not at all find any software updates to be installed?
That said, the vehicle has many modules so they might have to go through each module which takes time to check for updates. At least that is what my dealership personnel told me.

I have a 2020 GLE 350 and today, 3/11/2025, it did exactly like you have said. I was turning into a parking on my right. I stopped my car, switched the cameras, so I could see the parking slot on the screen. Just when I took the right turn into the slot, the car accelerated at the same angle and jumped onto the curb. The brake was not working, but I had the presence of mind to press the Park button on the gear lever and then the car stopped. No car damage or no injury, but it was a close call. Can we document this together to get a serious response from Mercedes Benz?

Sorry to hear that, MB likely has access to something called a blackbox or data recorder similar but not exactly the same to a flight data recorder, but the dealership doesn't have access to it. That blackbox should give more detail of what happened, including the operating parameters.

Another "probably not the case either" guess:
Is Route Based Navigation enabled? (I really dislike that feature.)

Dealer shop foreman said the computer showed nothing out of the ordinary, though the foreman said with this type of problem it may or may not show the incident. He said they have had issues with cruise controls, but he's hasn't heard of this problem before. He said he was going to check MB database for similar complaints
