This is a known issue with GLE 450 48v batteries over heating and causing loss of power and all function to control the vehicle. , For an unknown reason my vehicle was not part of a recent recall and probably should have been. I experienced the issue today and escaped tragedy. My battery light came on, then off, then a bright red battery light came on across the dashboard…then all of a sudden, my car lost all power with no warning. All while driving on the freeway 394! Luckily traffic was light and I was able to coast halfway up an off ramp. Then I got an overheating message. Reports show all cars were recalled, however mine wasn’t part of the recall!! I would like an investigation to include all cars in the years and models not just some of them.

There were two incidents that had similar symptoms: one before the dealership said they fixed and one afterwards. The issue is that while driving I would get three warning, all at the same time: coolant too hot, 48v battery malfunction, shut the engine off. The first time it happened immediately after I turned on the vehicle and within 5 minutes of leaving a parking lot. The second time it happened after about 3 hours of driving at highway speeds. After the first time it happened dealership said they fixed the issue by upgrading the software (battery software?). Both times it happened on the highway. The first time on the uphill, and vehicle immediately shut off and could not make it up the ramp. The second time in the tunnel on the flat road, could not make it to the exit. Both times created extremely dangerous situation as I had no time to take the exit and vehicle shut off about 30 seconds after warning popped up. The second time in the tunnel was especially dangerous as there was no shoulder and i had to stop in the middle of the right lane as cars were going at 60 mph by me. I was really worried for myself and my family. I have to trust that Mercedes is capable of fixing the issue and providing a reliable vehicle I can depend on and trust for the safety of my family.

1. After coming to a stop, foot placed on the pedal to accelerate through a neighborhood security gate, the car would not accelerate despite how hard I depressed the gas pedal. After approximately 3-4 seconds the car finally accelerated. 2. When coming to a stop the vehicle has a very hard “clunk” in the transmission to stop. Vehicle was taken to the dealership but they could not replicate the problem at the time so car was given back to me with “non replicable” issues.

1. FIRST MESSAGE: 48V BATTERY MALFUNCTION 2. SECOND MESSAGE: STOP THE VEHICLE COOLANT IS NOT WORKING VEHICLE IS OVERHEATING. 3. LOST POWER, I COULD ONLY DRIVE 10 MILES PER HOUR. I PULLED TO THE SIDE OF THE ROAD AND WAS ALMOST REAR ENDED BY A SEMI TRUCK. THERE ARE SEVERAL ONLINE OCCURRENCES REPORTING THESE SAME MESSAGES. IT IS EXTREMELY DANGEROUS WHEN A VEHICLE LOSES ALL POWER WHILE ON A BUSY HIGHWAY. THE VEHICLE WAS INSPECTED. MERCEDES AWARE OF A BULLETIN WITH THIS ISSUE.

I WAS TRAVELLING ON HIGHWAY WITH ADAPTIVE CRUISE CONTROL ON. WHEN NEAR THE EXIT, I PRESS THE OFF BUTTON FOR THE CRUISE CONTROL. TO MY SURPRISE, THE CAR DIDN'T SLOW DOWN, AND INSTEAD MAINTAIN THE ENGINE POWER TO KEEP THE CAR IN SET SPEED. I TRIED THE OTHER SETTINGS (OFF, CANCEL, SPEED DOWN) OPTION BUT NOTHING IS RESPONSIVE. SINCE I AM ON THE OFF RAMP ALREADY, I HAVE TO STEP ON THE BRAKE (THIS DOES FINALLY STOP THE CRUISE CONTROL) TO SLOW DOWN THE CAR. AFTER I COME TO A STOP AT THE STOP LIGHT, I NOTICE THAT THE AR VIEW CAMERA HAS A CONDENSATION IN THE CENTER OF THE CAMERA LENS (SEE FIRST PICTURE WITH 11/10 DATE). AT THE SAME TIME, MULTIPLE WARNING MESSAGE APPEAR ON DASH, INCLUDING "ADAPTIVE CRUISE CONTROL INOPERATIVE", "ACTIVE LANE KEEP ASSIST INOPERATIVE", AND A FEW OTHERS. THE CRUISE CONTROL INDICATOR REMAIN ON AND ACTIVE ON THE DASH (BUT SYSTEM ISN'T WORKING) UNTIL I GOT TO A SAFE LOCATION TO RESTART THE CAR. ALL ERROR MESSAGE WAS CLEARED AFTERWARD. A FEW DAYS LATER (11/16), I HAD THE CAR AT THE DEALER FOR INSPECTION. I MENTIONED THE ISSUE BUT THEY SAID THEY ARE UNABLE TO FIND ANYTHING WRONG AND CAMERA LENS WAS CLEARED AT THAT TIME. AFTER I GOT HOME, I NOTICE THERE ARE CONDENSATION AGAIN ON THE CAMERA LENS (SEE SECTION PICTURE WITH 11/16 DATE).

DRIVING DOWN THE HIGHWAY AT 70 MPH AND '48V BATTERY MALFUNCTION' WARNING GOES OFF, ALONG WITH A YELLOW CHECK ENGINE LIGHT. A FEW SECONDS LATER A 'COOLANT' ERROR MESSAGE POPS UP AND A RED CHECK ENGINE LIGHT COMES ON. CAR LOOSES POWER COMPLETELY AND I'M UNABLE TO ACCELERATE AT ALL. CALL FLASHES A MESSAGE OF 'PULL OVER AND TURN THE ENGINE OFF'. FORTUNATELY NO ONE WAS BEHIND ME AND I WAS ABLE TO COAST SAFELY TO THE SIDE OF THE HIGHWAY BEFORE THE CAR STALLED COMPLETELY. FOUND OUT THROUGH SEVERAL BLOG POSTS MULTIPLE OTHER 2020 GLE OWNERS ARE HAVING THE SAME SAFETY ISSUE AND THERE HAS BEEN NO RECALL BY MERCEDES-BENZ AND NO RESOLUTION FOR THE ISSUE. VEHICLES ARE SPENDING MONTHS IN THE SHOP AND EVENTUALLY BEING BOUGHT BACK BY THE MANUFACTURER OR DEALERSHIP. THIS IS AN INCREDIBLY DANGEROUS ISSUE TO LOSE ALL POWER AND CONTROL OF THE VEHICLES SPEED. I'M LUCKY NO ONE WAS ON THE ROAD NEAR ME WHEN THIS HAPPENED, OTHERWISE AN ACCIDENT ALMOST SURELY WOULD HAVE OCCURRED. MERCEDES SHOULD BE FORCED TO ADDRESS THIS SAFETY ISSUE IMMEDIATELY.
