2018 Mercedes-Benz GLE-Class Electrical System Problems

CASE NUMBER: [XXX] VEHICLE: 2018 Mercedes-Benz GLE350 --- EMAIL EXCHANGE TEXT --- From: [XXX] Sent: 1/14/2026, 12:11 PM To: [email protected] Subject: Re: Message From Mercedes-Benz USA: Case Number [XXX] Dear Ken, I want to clarify that my concern is not about support for “older technology” in a general sense, but about the confirmed retirement of factory-installed emergency and crash-response systems that were standard safety equipment on my vehicle at the time of sale. As previously noted, the mbrace system on my 2018 GLE-Class includes SOS/Emergency Call and Automatic Collision Notification functionality intended to contact emergency services in the event of a crash or airbag deployment, particularly where the driver may be incapacitated. These are safety systems, not discretionary convenience features. Your replies confirm that these safety functions are being permanently disabled, that no retrofit or replacement solution exists, and that the vehicle will continue to operate without the emergency communication capability it was originally sold with. I appreciate your acknowledgment, and I am documenting Mercedes-Benz USA’s position that these safety systems have been retired with no alternative provided. Sincerely, [XXX] On Jan 14, 2026, at 09:02, Mercedes-Benz USA [email protected] wrote: Dear [XXX] , I’m very sorry that these older technology features have been retired. Mercedes‑Benz is currently focused on supporting our present and next‑generation technologies, which unfortunately means that the former mbrace system is no longer maintained. If you have any additional questions or concerns, I would be more than happy to assist. Best Regards, Ken C. Mercedes-Benz USA (800) 367-6372 Mercedes-Benz Customer Care, 1 Mercedes-Benz Drive.

Safety issue with regarding the TCU (Telematics Control Unit). Active recall does not include my VIN# /Make & Model. NHTSA campaign number 22V365. My car has Constant SOS Inoperative Message after battery failure in 2021-2022.

The fuel pump has been failing and shutting off and has been hesitant when taking off. It can leave you stranded in the middle of the road or if you turn left in front of people the car may stall and can cause a crash. Yes and independent dealer and the dealer both know it’s a problem. I took the vehicle into a Mercedes dealer and the fuel pump had a recall on it and the dealer refused to replace it although I had a engine code that they could pull up referring them to the fuel pump and the fuel pump not priming as it should in every start up. The failure happened a few months ago and I took it in and the dealer drilled a home in the rear of my car and failed to replace the fuel pump, which was covered under the warranty. And the dealer admitted there was water in the trunk area which corroded the fuel pump.

The contact owns a 2018 Mercedes-Benz GLE 350. The contact stated that water had entered the vehicle through the sunroof. The vehicle was taken to an independent mechanic, who determined that water intrusion through the sunroof had damaged the batteries. The mechanic replaced both batteries. The contact related the failure to NHTSA Campaign Number: 23V854000(Structure); however, the VIN was not included in the recall. The dealer was notified of the failure. The vehicle was not repaired for the water intrusion failure. The manufacturer was made aware of the failure. The failure mileage was approximately 81,000. The VIN was unavailable.

The contact owns a 2018 Mercedes-Benz AMG GLE43. The contact stated that the sunroof failed to open, and there was a fracture causing water to leak into the cabin of the vehicle from the upper-right side. The vehicle was taken to the dealer to be diagnosed. The dealer determined that the motor and tracks for the sunroof had failed and needed to be replaced. The dealer stated that the entire unit needed to be replaced due to previous parts no longer being compatible with the new improved parts. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 49,000.

ONGOING ISSUE WITH THE INFORMATION MONITOR FREEZING, PARTICULAR TO THE NAVIGATION FUNCTION. SHUTS DOWN AND ATTEMPTS TO REBOOT REPEATEDLY. MB ATTEMPTED A FIX RE SOFTWARE, HOWEVER, ISSUE CONTINUES. SHUTTING OFF THE ENGINE, LEAVING PARKED FOR AN HOUR OR TWO DOES NOT CORRECT THE SYSTEM. MAY OCCUR SHORTLY AFTER BACKING OUT OF THE GARAGE OR SHORTLY AFTER BEGINNING TO DRIVE. OVERNIGHT PARKING SEEMS TO CORRECT THE IMMEDIATE ISSUE. DURING THIS TIME, ONLY OTHER FUNCTION THAT OPERATES IS THE RADIO; CANNOT USE VOICE COMMANDS, TELEPHONE BLUETOOTH, ETC. HAVE ALERTED MB DEALER IN SAN ANTONIO WITH COPY TO MB USA, HOWEVER, NO RESPONSES. GOOGLE SEARCH HAS INDICATED VARIOUS MODELS MAY HAVE EXPERIENCED SIMILAR ISSUES OVER SEVERAL YEARS, HOWEVER, NO INDICATIONS OF CORRECTIVE ACTION. PRUDENT TO ALSO CARRY A GPS ALTERNATIVE SUCH AS A MAP, GARMIN OR OTHER BRAND IN THE EVENT OF FAILURE WHILE ON A TRIP. THIS OCCURRED IN LATE NOVEMBER 2019 AND AGAIN JANUARY 2020.

WHILE PARKING CAR IN A PARKING SPOT IN PRIVATE OFFICE PARKING, THE CAR ACCELERATED ITSELF (WHILE PRESSING THE BRAKE TO STOP IT) AND RAN INTO FRONT WALL. THIS SIMILAR PROBLEM HAS SHOWN EARLIER WHERE CAR ACCELERATED ITSELF WITHOUT CAUSING ANY ACCIDENT. APPARENTLY PROBLEM EXIST WHERE CAR SOMETIME ACCELERATE ITSELF. LAST TIME ACCELERATION CAUSE CRASH INTO FRONT WALL WITH SEVERE DAMAGE TO THE CAR. NOW CAR IS AT BODY SHOP FOR REPAIR. CAR WAS HEADING STRAIGHT INTO GLASS WINDOW BUT DRIVER TURNED THE WHEEL TO RIGHT TO SAVE GLASS WINDOW AND DIRECTED TOWARD THE PILLAR. AS THIS CAN BE SEEN IN THE PICTURE. THIS IS THE REASON FOR THE CRASH TO BE AT AN ANGLE, THIS WAS DONE TO AVOID CRASHING INTO BUILDING WINDOWS AND INJURING INHABITANT OF THE BUILDING.
