On April 15, 2026 at approximately 1:30 PM PT, I entered my 2023 Mercedes-Benz EQE SUV 500 4MATIC (approximately 20,000 miles) in my garage. The vehicle was not plugged in or charging prior to entry. I opened the car, sat in the driver's seat, and authenticated via the fingerprint scanner. The seat began adjusting to my stored profile position. While the seat was adjusting, I tapped the center console to open Apple CarPlay. The seat stopped moving midway through its adjustment, and what appeared to be every warning light on the instrument cluster illuminated simultaneously. I observed dozens of yellow and red warning icons, including a towing/recovery indicator. A number of warning messages also appeared on the screen. I manually adjusted the seat using the door-side controls. I attempted to shift into reverse to back out of the garage, but the vehicle would not engage. I then tried shifting into drive and the vehicle similarly would not engage. The drivetrain was completely unresponsive. I exited the vehicle, locked it, and re-entered to attempt a restart. All warning and system lights returned immediately and the vehicle again would not shift into any gear. I then connected the vehicle to my home charger. The charge port indicator on the vehicle flashed red, indicating it would not accept a charge. I disconnected the charger and attempted to start the vehicle a third time with the same result. I left the vehicle and took another car. The vehicle sat for approximately 45 minutes. At approximately 2:20 PM PT, another household member started the vehicle. It started normally with no warning lights and was able to drive without issue. The vehicle has been driven twice since this incident. On the following day (April 16, 2026), the Active Brake Assist system displayed a warning message indicating it is not functioning. This system was working normally prior to the April 15 incident.

I was driving back to my house in york, PA. My car all the sudden changed the gear from “D” to “N”. My gas meter was showing 106 miles. my didn’t give sign or alert before it shifted the gear from D to N. I was driving on highway and this was major safety concern as I could have hit by cars coming on highway speed. We had this similar incident last year as well but we were at traffic light stopped so we didn’t realize that time that car shift the grear by itself. Once we fill the gas, we were able to drive back home but it was scary and big safety concern that car doesn’t give any notification or alert for low fuel and change gear all the sudden.

Pertaining to the recall of the 2023 Mercedes Benz EQB300. There is no resolution or remedy for this recall. Currently this is my only means of transportation and I do not feel safe at all driving it. I contacted Mercedes Benz for a buyback or loaner. No one senna to be concerned. The fire risk puts me and my children life in danger. I rent my house and have renter’s insurance but a vehicle fire will not be covered if damage occurs

Hello. Since I bought this car in 2015. Every now and again it will go into park when driving and tge car will stop suddenly. It has done it a few times over the years and it’s quite scary. Mercedes has put me off on you, without addressing the situation or looking at the car, unless I pay first it. I think there is a mechanical defect on this car and it is quite dangerous

“My 2023 Mercedes-Benz EQB 350 is subject to NHTSA recall 26V073 involving a high-voltage battery defect that may cause a fire. The manufacturer has instructed me to limit charging to 80% and to park the vehicle outside due to fire risk. This significantly reduces the vehicle’s usable range and creates safety concerns. Due to this 80% charging limitation, the vehicle no longer provides sufficient range for my daily commute and cannot be reliably used for its intended purpose. The manufacturer has stated that the permanent remedy (battery replacement) is not yet available, with an estimated timeline extending into December 2026. I opened a case with Mercedes-Benz on April 3, 2026 (Case #[XXX]), and as of today no case manager has been assigned despite multiple follow-ups. As a result, I am operating a vehicle with a known safety defect that cannot be repaired and cannot be used as intended. This represents both a safety risk and a failure to provide a timely remedy for a safety recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
