Mercedes-Benz GLE Safety Recalls

While driving on a limited-access highway at 65 mph with cruise control engaged, the vehicle unexpectedly reduced speed to 50 mph without any driver input under steady traffic and road conditions. No braking was applied by the driver, and no warnings or alerts were displayed prior to or during the speed reduction. Separately, the vehicle’s displayed speed-limit information was unstable during highway driving. The display repeatedly changed between the correct posted speed limit, a blank display, and “---” under consistent conditions, without changes in roadway, signage, or map context. This behavior was observed multiple times and was captured on video recording. The unexpected reduction in speed created a safety risk due to loss of speed relative to surrounding traffic.

I am writing to lodge a complaint regarding my brand new vehicle, which has been in the shop for over a 3 months since its purchase on [XXX]. I picked up my 2026 Mercedes GLE 450 from Baker Mercedes Benz in Charleston, and it started malfunctioning about 20 minutes into the trip home. The following day I brought it into my local Mercedes dealership, Myrtle Beach Mercedes Benz, for inspection. The first available appointment was 10 days away, so I was unable to drive the vehicle for that period after the purchase. I brought the car in on October 10th, and a few hours later, I received a call stating that it was ready, and it was just an upgrade that needed to be installed. However, upon returning to the vehicle at the service department, I noticed the engine light was still illuminated. They were unable to diagnose the issue at that time. The dealership contacted me a week later, informing me that Mercedes was opening a case, and there was no estimated timeframe for resolution. In the meantime, I have been provided with a loaner vehicle that does not have a tow package, which was the primary reason for purchasing the vehicle. Consequently, I have been unable to boat or jet ski for the past 3 months. Our summer season has largely ended, and I have missed at least 60 days of pleasant boating weather due to my new Mercedes being inoperable since my delivery date of [XXX]. The vehicle was sent to a local body shop called Darrell's where it has sat for at least 10 weeks. The problem is that the main ground for all the electronics was never tightened or welded. It burnt all the carpet in the back and could have easily caught fire with my family inside . I smelled something burning on the way home but wasn't sure what it was. The auto body place said we were lucky that the vehicle didn't catch fire with my family inside. MBUSA is only willing to compensate me for the price I paid for the car but not for all the additional expenses incurred since inception.

I was driving in I75 highway south in Michigan and heading to Ohio. I had around 70 mil/hr ish speed and was trying to pass a commercial truck. I Just turned on rear window wiper to clean it and once it started to work, the vehicle had a very hard brake for a couple seconds which the my seat belt pushed me hard to the seat to avoid of my head to go forward to windshield. Fortunately it was very quick brake and didn’t caused any accident, but I was worried that it was repeated again and had a lot stress until I arrived at the destination. I am guessing probably either park brake was engaged without touching it(software or part issue) or the sensors for front and emergency collisions had the bad function.

On multiple occasions, the vehicle has unexpectedly lost acceleration while driving. Specifically, while traveling on the highway, the vehicle will suddenly drop speed and fail to respond when pressing the accelerator. This creates a dangerous situation, as I am unable to maintain speed with surrounding traffic, increasing the risk of a collision. This issue appears to occur without warning and significantly impacts the safe operation of the vehicle. A sudden loss of power on a high-speed roadway is extremely hazardous and poses a risk to both myself and other drivers.

Panoramic sunroof exploded when I was driving not external force was involved to make the sunroof explode the sound was like a gunshot small particles of glass fell to my face

12 V battery completely drained while in operation resulting in me being stranded and requiring the vehicle to be towed.

We've had this car on lease for 23 months, and it has had an escalating pattern of electronic, mechanical and brake issues. Earlier today, on January 5, the car started to slow down and started shaking on the highway today and when I used the brakes the full body of the car started rattling and the brakes were far less responsive than they should have been taking far longer to decelerate than safe. There was an alarm with a turtle warning me to move over. On January 4, We parked our car in a parking lot and went into a store, when we returned all of the windows were lowered and the moonroof's window was also retracted. The car was beeping and making loud noises and then had issues starting. Prior to both of these issues, the car has taken to Mercedes repeatedly for locking passengers into the vehicle and blaring alarms, not allowing passengers to leave and the seatbelts will not retract. The airbag system has also malfunctioned during these periods. Mercedes has repeatedly been informed of these issues and has claimed that there were bugs in the car's code that they had fixed; however, each time they have fixed the issue a new issue has arisen. In late November 2025, a representative from Mercedes corporate asked for us to take the vehicle back to dealer for further inspection after which the dealership said they had carried out major updates and returned the car in early December. After that the car had been hardly driven until this week. This was the first major drive of over 60 miles.

The MPH Sign Recognition mistakes 30mph when the sign reads 70mph.When the Cruise Control is set for 70mph the car begins to brake by itself thinking it is 40mph over the posted limit.This may cause a rear end collision. As a result I have discontinued using the Cruise Control to avoid an accident. This problem may exist on other late model Mercedes-Benz with the Sign Recognition option.

The panel between the windshield and the sunroof shattered with cracks going the full width of the roof at the top and bottom of the glass panel.
