2023 MERCEDES-BENZ EQE 350 4MATIC Complaints

Severe, life-threatening autonomous safety system and powertrain failures in a 2023 Mercedes-Benz EQE SUV. The vehicle exhibits sudden, violent unintended acceleration, unprovoked emergency braking, and steering lockups. On multiple occasions, including at 75 MPH on the freeway and 45 MPH on city streets, the vehicle abruptly applies maximum braking force down to a near-stop without driver input or any road obstruction, nearly causing multiple catastrophic rear-end collisions with semi-trucks and buses. Conversely, the vehicle experiences sudden unintended acceleration; during one severe city street incident, the vehicle unexpectedly accelerated from 40 MPH to 60 MPH while the driver was actively braking, causing the brake pedal to feel completely locked, stiff, and unresponsive for several seconds before stopping. While stopped at red lights, the vehicle violently surges and rocks forward/backward as if wanting to accelerate without driver input. The steering assistance system abruptly locks up or pulls hard to the right without warning, requiring the driver to physically wrestle control to maintain lane alignment. The braking system suffers from severe malfunctions, including the pedal randomly repositioning itself lower while driving and dropping completely to the floor during parking, causing the vehicle to roll until pumped. The electronic parking brake intermittently fails to release when shifting into drive/reverse. Additional systemic electrical and safety defects include: complete instrument cluster/gauge blackouts impairing speed monitoring; steering wheel physically blocking gauge visibility; total failure of rearview/surround-view cameras, blind spot monitors, and mirror controls; exterior door handles failing to deploy; rear trunk malfunctions; severe high-voltage battery range loss; and continuous infotainment/navigation crashes. Authorized dealerships have failed to repair these critical safety components across 4 distinct repair attempts.

1. March 11th: First Incident was when crossing a railroad crossing in [XXX] ~2:00pm the car suddenly braked and seatbelts tightened very strongly and immediately stopped, Automatic braking was engaged. There was a car Behind me and barely was able to brake and avoid rear ending me. We took it to dealer in Fremont (mb of fremont) a service advisor checked the car and drove it for a while (Joe Defraeitas) they were not able to find any issue and sent us back. asking us to bring it back if it happens again. my speed was between 30-40mph. I don't remember if there was lights flashing warning or not. all I remember it suddenly halted and stopped and I was really scrared. 2. March 17th at a very close time to ~2:00PM at exactly same place this issue happened again, this time I was with my daughter [XXX] ) and same exact thing happened; luckily no cars were behind me at that time again, same as before speed 30-40mph and no warning lights that I remember. this time we took the car to service dealership on March 20th and they asked us to schedule an appoint and we did bring it back on march 26th. The RO# from mboffremont is XXX; again same advisor. they claimed they checked all the software and sensors and nothing wrong with the car. 3. Third incident on Apr 7th at ~12:00 on [XXX] [XXX] by the railroads crossing as well, luckily no cars were behind me and speed was 20-30mph this time is didn't do full stop. We reported it this time to MB dealership in Pleasanton, CA. This was the original dealership where we bought the car. again they claim nothing is wrong with the car. The service manager mentioned that will look inot this carefully, but unfortunately a service advisor called and said nothing is wrong with the car and they were not able to (Service Advisor is [XXX] ).

While driving down the highway late at night, with no other cars around, the panoramic sunroof exploded, throwing shattered glass everywhere. The window was not hit by an object and had no previous damage. Shattered flying glass while moving at highway speeds caused a momentary loss of control.

ALL TIRES MENTIONED HERE ARE PIRELLI ZERO RUN FLAT TIRES (MBQ-8-40-3071, PIRELLI 255/35R21) My Mercedes EQE equipped with 21” AMG wheels has suffered six blowouts using Pirelli ride fat tires that came with the car. It seems the car is too heavy for this tire/wheel configuration, which is a standard option and was installed on the car when I leased it. EQE, EQS, and S Class owners have reported the same problem in online forums over the last several years, specifically with 21” AMG wheels and ride Yat tires. All cases of this happening presented immediate risks, fortunately no crash occurred. Four incidents damaged one front tire, one incident damaged a front and rear tire. Mercedes should recall vehicles with this wheel and tire combination. The car has just 22,000 miles, bringing the mean time between failure for six tires to just 3,667 miles — well below the norm. I have owned many cars and typically average about 75,000 or more miles per tire, and never have catastrophic blowouts. The blowouts seem to occur because the Pirelli ride-flat tires have exceptionally stiff sidewalls that appear to fail under lateral impact resulting from even the most minor road imperfections. The car’s forward camber, low center of gravity, and heaviness exacerbate the problem. Two blowouts occurred while transiting over standard slightly recessed steel manhole covers traversed by thousands of vehicles daily. I have driven other Mercedes loaner vehicles with no incident. The problem appeared within a week of vehicle lease (May 2023) and I lost three tires in October 2025, within days of each other: once the day after a prior repair. I was also stuck waiting for repairs on a busy highway for 3 hours. This is a dangerous situation and needs a recall. Once is bad luck, twice is peculiar, three times is a pattern, four times is a design Yaw, and six times it’s negligence. I think the car is great otherwise but this is a dangerous design flaw and needs to be addressed by the company.

It happen 4 times during normal driving on local roads on nice weather and no car infront . My car just stop violently and make a lound noise as if it hit something .It happen very quick and became normal as if nothing wrong .Reported and brought car to dealer after a week there not found any defects.The 5th times happen when car pull out from driveway with no car around. I belived this a saferty hazard because if it happen during driving on hiway i could get hit from behide for sudden stop.

When I turned on the car this morning, the instrument cluster screen was black and would not activate. Because of this, there was no way to determine speed or to utilize driver assistance functions. This created significantly unsafe condition because I had no gauges or dials to assist. I turned the car off multiple times and attempted to reset it and the instrument cluster screen was still black and nonresponsive. This appears to be a known issue from searching the Webb for Mercedes electric vehicles.

On several occasions the vehicle aggressively stopped and jerked as if someone hit my car from behind. I took it to the dealership and they thought it was a software malfunction issue, since there were recalls on the vehicle. I received my car back from the dealership and in a week of receiving my car, the issue happened twice. This has been extremely scary especially because on two occasions a car almost hit me in the back and both times my son was in the car. The car has done this where there were not any cars around and the car falsely believes there is a car around a collision will occur. Today , the car did it twice. The first was while I was taking my son to school going slowly. The second time this happened was while I was stopped at a red light. The dashboard then had a red triangle with an exclamation mark inside. Every time the car stops it caused my neck and back to hurt and I am afraid a car will actually hit me from behind.

On Mon, [XXX], my father was involved in a single car accident in the family's Mercedes-Bens EQE 350 (all electric) vehicle. When he was in driveway, he claims he was on the brake when the car suddenly accelerated on its own. It destroyed the garage door and then went through the garage destroying property, the attic staircase, and the frame of an interior wall into a bedroom. We have pictures of the damage. Emergency repairs were required to stabilize the frame of the house with more 2x4s. The insurance company says he likely confused the brake and gas pedals, but he's convinced that he was on the brake when it suddenly accelerated on its own. Importantly, no auto-emergency braking occurred, no airbag deployed, and no other emergency systems engaged. We received no indication that the system reported an accident. I was able to source an online forum where individuals recounted identical fact patterns about being on the brake and the Mercedes EQ vehicle accelerating dangerously on its own. We believe that the issue was a electrical computer malfunction and yes, the car is available for inspection. It is currently being repaired at a collision shop in Edison, NJ. I have sent a general service request to Mercedes Benz to encourage an inspection from them. The problem has not yet been sourced or reproduced and no warning lamps or messages appeared prior, during, or after the accident. Here's the MB electric vehicle community message board describing similar accounts [XXX] I am messaging to initiate a safety report about this vehicle since this issue could potentially cause a fatality if not properly addressed.
