2023 Mercedes-Benz EQE 350 4MATIC Problems

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.

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.

My Mercedes EQE equipped with 21” AMG wheels has suffered six blowouts using Pirelli ride flat 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. Various 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 flat 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. 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 flaw, 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.

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.

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.
