2021 Mercedes-Benz GLE Class SUV 4WD

In the middle of driving it down the road when - without warning -- the instrument panel went black, the entire panel. My husband was on his way to the dealership to replace a tire when this happened. Though he was able to make his way to the dealer, we consider this event to be a serious safety issue, given that there was a partial power outage involving the components the driver relies upon to drive the car - for example, the driver's side instrument panel has indicator lights for the odometer, gas & oil levels and especially, the gear shift controls. My husband asked the dealer to look into the problem and was told a 10682 Electrical test was performed showing that the Head Unit had a fault. When tested again it showed no fault & no available software updates, so they cleared the Head codes and ran the test, which came up negative.

What component or system failed or malfunctioned, and is it available for inspection upon request? The digital dashboard (MBUX) screen that driver is dependent on, all of a sudden go blank with no access to heaters, no display, with no GPS and no dash heater. This screen is controlled by a control unit which is right under the passenger seat and is very sensitive even to few water droplets. Yes, the component is available for inspection. How was your safety or the safety of others put at risk? With such a control unit that is sensitive to few water droplets, if a passenger sitting in the second row has wet shoes or shoes with snow or drops some water, can short circuit the unit and can result in blanking out the digital screen. On a cold day or during night on a highway, the digital dashboard screens all of a sudden go blank and the dash can get foggy, resulting in driving distraction and low visibility for driver. Heaters can be turned on manually but result in burning smell in the car. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealer has inspected the problem and have also confirmed other customers also had similar issues. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by the Mercedes Benz dealer service department (where I leased ) and they have confirmed that few water droplets have short circuited the control unit which resulted in blanking out the screen. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No messages or warning lamps or signs have been displayed prior to the failure. But we smelled something burning in the car before this happened. This appeared on Jan 9th evening 5 PM on our way from Pittsburgh to Columbus on the highway.

It is incredibly distressing to have experienced an issue that is widely reported in this database and online forums, and remains unaddressed by MBUSA. It also seems to be an entirely preventable issue that can be fixed via a software update. The issue relates to a malfunction of the 48V battery that made the vehicle inoperatable. It happened in the midst of winter and we would be been in a dire position if our family did not come to the rescue to pick us up. The vehicle had to be towed to a dealership. Here is the dealer summary: 48v software vehicle has no power, connected jumper, battery lights on in dash, towed into shop and connected battery charger, performed quick test, found codes in 48v- B183349 and B183371 , referred to Topic # LI54.10-P-069698 remedy #2, performed guided test for B1833349, as per guided test updated 48v software and commissioned, after completion vehicle started normally, performed extended test drive and multiple short test drives to verify vehicle now operating as designed again, lights no longer present in dash.

Recall 21V354 has not been completed. They have had since May 14. I have contacted MBUSA twice and they will not give me a completion date.

On two separate occasions recently, the vehicle suddenly lost all power without warning and stopped. Luckily, these incidents did not occur while driving in high speed traffic, and the car restarted once shut off. When it lost power, all warning lights came on at once. After the first incident, dealer "updated the 48v system and esp control modules and The vehicle is operating as designed." The first incident was on November 9, the second incident was on November 29.

GLE53 would not start. The car threw an error stating 12v battery malfunction.(Impacted the 48V battery) This essentially disables the vehicle completely. This is 2021 GLE53 with less than 5000 miles. There is also an issue with the side-view mirror and wind noise.

Issue-The car brakes aggressively using cruise control (Mercedes Distronic) with no driver intervention. This dangerous condition can cause an accident. Using my advanced cruise control…the issue is my set speed was changed along with acceleration or braking when a traffic sign is misread. I have turned off the only setting controls Traffic Sign Assist & Route Based Speed Assist but there is no change. Example of issue-My car was misreading 80mph as 60 & braking aggressively. .My prior 2020 GLE misread signs less often and did not change the speed setting or brake the vehicle. The Dealer applied all available software updates. After all the updates my car continues to adjust set speed to every misread traffic sign. For example recently I had my speed set at the posted speed of 80 and the car read a sign as 70, changed the 80 to 70, and started braking aggressively. In Idaho there are stacked signs-the upper one reads 80 and below “Trucks 70” so this happens about 50% of the time. The vehicle misreads signs often.

The contact owns a 2021 Mercedes-Benz GLE350. The contact stated that the rear brake lights did not function properly when the brake was applied. The contact was made aware of the failure when he noticed that after slowing down to stop, other vehicles from behind were stopping close to the rear of his vehicle. The contact tested the rear brake lights and noticed that they did not illuminate as soon as the brake pedal was depressed. There were also other failures where the tailgate would open about 6 inches and the moonroof would open about 3 inches inadvertently. The transmission also shifted inadvertently. After coming to a full stop, the Eco mode would engage and turn off the engine, but when the engine turned back on, the vehicle would shake abnormally. The vehicle was taken to the dealer and diagnosed that it was normal for the rear brake lights to not illuminate immediately when the brake pedal was depressed. The vehicle was not repaired and remained at the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 500.

I was driving at full speed on the interstate (75mph) when the vehicle died completely. I had only seconds to maneuver the vehicle to the shoulder. There was no indication of a service issue with the vehicle prior to this incident. The car is/was approximately 2 weeks old, with about 500 miles of usage. Vehicle would not restart so I could attempt to get to a safer location.

THERE ARE NUMEROUS REPORTS OF THE 48V BATTERY FAILING ON MULTIPLE MERCEDES MODELS USING THE 6 CYLINDER WITH ISG ENGINE. MERCEDES SHOULD DO A RECALL TO REPLACE ALL 48V BATTERIES AS THIS PROBLEM MAKES THE CARS UNRELIABLE AND UNSAFE TO USE AS SOMETIMES THIS 48V BATTERY SYSTEM FAILS WHILE DRIVING.

WHILE THE CAR IS IN PARK AND IDLING, THE VEHICLE WILL NUDGE FORWARD REPEATEDLY. THE CAR DEALERSHIP APPEARS RATHER CAVALIER ABOUT THIS ISSUE BUT IT LEADS TO LITTLE TRUST WITH THE VEHICLE. THE CURRENT MINDSET IS THAT AT SOME POINT THE VEHICLE MAY PROPELL MORESO THAN A NUDGE UNEXPECTEDLY CAUSING A SAFETY ISSUE.
