Vehicle: 2018 Mercedes-Benz GLE 350 Component: Electrical System / Electronic Key Detection / Door Locking System My 2018 Mercedes-Benz GLE 350 has locked with its only electronic key fob inside the vehicle on three separate occasions. Most recently, my dog was trapped inside, and I was left stranded waiting hours for roadside assistance. The key fob has a fresh battery. Mercedes-Benz representatives have repeatedly insisted that this should not be possible. However, Kyle, a manager at W.I. Simonson Mercedes-Benz Service Center in Santa Monica, acknowledged that this sometimes happens when a key is inside a purse and admitted that he had experienced the same problem himself. This raises serious concerns about the reliability of the vehicle’s electronic key-detection system and its safeguards against unintended locking. A vehicle that locks with its only key inside can create a dangerous situation, particularly when a child or animal is trapped in extreme temperatures or an emergency. Despite the recurring nature of this problem, Mercedes-Benz has not provided a technical explanation or corrective solution and sought to charge me for emergency unlocking. I request that the federal safety agency investigate whether this represents a broader safety defect affecting Mercedes-Benz vehicles equipped with KEYLESS-GO, review similar consumer complaints, and determine whether corrective action or a safety recall is warranted.

Rear view camera fails to initiate when placed in reverse. Screen doesn’t even try to switch to camera view. Exact same issue found in same make and model recalled with different vins. For some reason this one isn’t included in the recall. Car only has about 58,000 miles. Started around 56,000 miles. Note that camera even folds out of lift gate like normal when placed in park.
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.

The low beam visibility on this vehicle is extremely dangerous. It's as if you have no headlights on. They can inspect anytime. With low night visibility. Driver is not able to see the road or person which causes a delayed response because of visibility. Driver puts on highbeams to be able to see which blinds others or shouldn't be driven at night. Plenty of times, I could have been in an accident or didn't see someone. My eyes are 20/20. Yes, it was reproduced. We tried after market headlights as well, but it's the same issue. Yes, I have complained to manufacturer more than once, but if there is no recall. They want a diagnostic fee and ignore it. This has been ongoing since the car was purchased. Even the GLS 2017 have the same issue.

The contact owns a 2018 Mercedes-Benz GLE 350. The contact stated that while the vehicle was parked in a pharmacy parking lot with the hold feature engaged, the driver released the brake pedal. Immediately afterward, the vehicle suddenly accelerated forward approximately 75 feet. The driver attempted to stop the vehicle by depressing the brake pedal; however, the brakes failed to respond. The vehicle continued moving, went over a curb, into a ditch, up a hill, and through a cement block wall before coming to an abrupt stop 5 feet from a house. The driver sustained arm and shoulder injuries, including emotional trauma, and was transported by ambulance to a hospital for medical treatment. The air bags deployed during the crash. There was no reported fire. A police report was filed, and the vehicle was towed to a tow lot. The driver attempted to contact a local dealer but did not receive a response. The vehicle has not yet been diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 91,000.
Owners of affected Mercedes-Benz vehicles were given no meaningful advance warning that core, built-in safety and emergency communication systems would be permanently disabled. No replacement system has been offered, no retrofit path exists, and no alternative emergency solution has been provided. The manufacturer has instead unilaterally orphaned these vehicles by discontinuing backend support required for functionality that was present at the time of sale. These vehicles were manufactured and sold with non-paywalled, standard safety features, including automatic emergency call (E-Call/SOS), crash notification, and airbag deployment communication designed to contact emergency services when a driver may be incapacitated. With the discontinuation of backend services, these safety-critical functions will no longer operate, meaning there will be no automatic communication of airbag deployment, crash events, or emergency assistance requests, despite the physical hardware remaining installed in the vehicle. In addition, connected vehicle functions that support vehicle location, tracking, and remote access—features that can materially assist in emergency response, theft recovery, and post-collision assistance—were removed without explanation, compensation, or transition plan. These systems simply ceased to function, leaving owners without clarity, notice, or recourse. As a result of these actions by Mercedes-Benz, affected vehicles are now materially less safe than when purchased, through no fault or action of the driver or owner. A vehicle originally marketed and sold with integrated emergency response capability has been degraded after sale, creating a safety risk in precisely the situations these systems were designed to address. This issue concerns the post-sale removal of safety-critical functionality, not optional convenience features, subscriptions, or infotainment services.
While driving, the vehicle’s serpentine/fan belt snapped. The loose belt struck and pulled out a sensor plug. Immediately the engine shut down and was later found to be seized. The vehicle had no prior warnings or known issues and was maintained according to manufacturer recommendations. There were no other warning signs ahead, the car is always maintained. I have records of all the maintenance, and there was not a single Check engine light, or any other kind of issue. Consequence: Engine seized, vehicle not drivable, substantial repair or replacement required. •Condition & maintenance: All services up-to-date, regular oil changes, no previous related issues. •Supporting documentation: Mechanic’s inspection report, service records, tow bill, photos of belt damage and sensor plug. •Impact: Unexpected catastrophic failure at low mileage; potential defect in belt/pulley/auxiliary-system interface posing risk of sudden breakdown. •Request: Investigation of whether this is an isolated failure or a possible defect pattern.
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.
Cannot shift the gear from P to any other positions, and unable to move the car. The issue has been existing from mid 2022, three years ago.
