2022 Mercedes-Benz GLE 350 Owner Complaints

For approximately two years, I reported recurring moisture/condensation inside the RIGHT headlamp assembly of my 2022 Mercedes-Benz GLE 350 to Mercedes-Benz. I was repeatedly advised that the condensation was normal. The condition progressively worsened. The vehicle is now displaying headlamp warning messages and the RIGHT TURN SIGNAL associated with the affected headlamp is no longer functioning. I am also receiving repeated warning messages related to the headlamp/turn-signal malfunction. The loss of the turn signal creates a safety concern because I cannot reliably signal my intention to turn or change lanes to other motorists. Mercedes-Benz has now advised that the headlamp assembly requires replacement. The affected component is the RIGHT headlamp. For completeness, the vehicle previously sustained an unrelated sideswipe on the LEFT side, during which the LEFT headlamp was scuffed and replaced through insurance. There was no frontal collision, and the present moisture intrusion and signal failure are occurring in the RIGHT headlamp on the opposite side of the vehicle. I am reporting this to NHTSA because a condition Mercedes-Benz previously characterized as normal has progressed from condensation inside the headlamp to warning messages and failure of a safety-related signaling function. I am concerned that similar moisture intrusion in this headlamp assembly could affect other vehicles.

When I got gas the estimated range indicated 308 Miles. We traveled approximately 134 Miles the estimated range was at 86 Miles it was dropping rapidly but average miles indicated 26.5 MPG. The next day we added fuel again and we were at 382 Miles. Then we drove 70 miles and the fuel indicator was showing that our range only decreased 15 Miles. During the trip the range increased multiple times and between the two days we traveled we did not know how much fuel was left in the car. The first trip it showed that we burned half a tank and the second day it showed we hardly burned any gas. This particular model has Open Recall for fuel pump system issues and display software. We were afraid that we were running out out of gas and would not be able to complete our trip or run out of gas in the middle of the highway.

Check engine light came on. Called dealership on a Thursday and again on Monday after it stayed on all weekend. Was told to bring in vehicle for diagnostics and to have a ride home. Half way to the dealership the car spuddered and I had to coast to the shoulder of the road. After a few minutes, I restarted the vehicle and drive slowly to the dealership, barely making it it the shop. The service advisor indicated it could be the cylinder head even before running diagnostics because it had happened to numerous other customers. It was a defective cylinder head. The repair bill was over $10,000 but Mercedes offered a $3,500 assistance credit. After doing some research on the internet, this appears to be a widespread issue.

Incident

Sep 19, 2025

While driving at 65 mph on Florida’s Turnpike (SR 91) at approximately 5:30 PM EST, the panoramic sliding sunroof panel (Mercedes-Benz part #167-780-20-00) spontaneously shattered without any impact or warning. Conditions were partly cloudy. No vehicles, debris, or construction were nearby. A loud explosive sound occurred overhead, followed by glass shards falling onto the roof and rear spoiler. The roller sunshade was open, and the operable glass section was closed. No glass entered the cabin. Startled by the sound and visible debris, I instinctively braked and swerved, almost losing control. Post-incident inspection showed a large portion of the panel was missing, and scratches and paint damage were visible behind the failure point. The vehicle was brought to a Mercedes-Benz dealership the next morning. Staff immediately acknowledged similar failures and stated they had seen and repaired multiple panoramic sunroof issues across the lineup, especially in hot weather. Although this type of failure is typically covered under the 4-year/50,000-mile warranty, it was denied due to the vehicle’s mileage (58,099). Replacement is estimated at $2,700 and is pending due to part backorder. The incident was independently confirmed by a Mercedes-Benz dealer, an independent repair shop, an auto glass facility, and an insurance representative. The auto glass technician noted that Mercedes-Benz uses thin tempered glass rather than laminated or thicker alternatives, which may increase the risk of spontaneous failure. This failure created significant safety risks including driver distraction, potential for secondary collisions, potential injuries from airborne glass, and road debris hazards. If the operable glass section had been open, glass shards may have entered the cabin, further increasing the risk of injury to myself, other vehicle occupants, or other road users. I request that NHTSA investigate the design and failure rates of this sunroof panel and similar components.

Check engine warning light came on. Called dealership and they could not do a remote diagnostic so they made plans to pick up the car which was about 2 weeks after the problem was alerted. See attached repair invoice. The problem was a known issue with the cylinder head compression leakage. “Removed cylinder head and disassembled to find excessive play in exhaust valve guides and abnormally worn exhaust value seats. Replaced cylinder head.” This issue impacted engine performance, including vibration and lack of acceleration. See attached letter to Mercedes which we have received no response.

I dropped my [XXX] to a class and was driving the car to run an errand, when I experienced a sudden and total brake failure. The first couple of times I hit the brakes, it felt a little too squishy, but I could still stop the car. Within two minutes, by the time I got to the next traffic light, I was unable to stop the car. Luckily I was at low speed and was able to turn into a residential neighborhood immediately and somehow stop the vehicle within a reasonable distance. Fortunately, the street I turned into, had no cars parked nearby. This was a frightening experience and could have ended very badly for my family had we been on the freeway. Please note - My car was serviced by Park Place Mercedes in Dallas only 2 days earlier, I had not even driven it 50 miles after it was serviced, when the brakes failed on me. I had the car towed back to Park Place Mercedes in Dallas, and they told me there was an air pocket that caused this issue.

Got a notice of a recall on the Nuna Rava and was told to order a remedy kit right away. I also checked to make sure the harness was locking in place. It was not and the car seat was unsafe to use. I order the remedy kit 2 weeks ago. Was told it was sent out and kept emailing to find out the status. I finally ask to have a supervisor call me as we could not take my [XXX] son in our car anywhere. The supervisor informed me that the remedy kit was not mailed out and that they were back ordered with no ETA in the near term. Now I have a dangerous and defective car seat and the manufacturer will not reimburse me for a new one, send me a new replacement seat, or even provide me with a remedy kit in a timely manner. This is completely unacceptable and I’ve lost complete trust and confidence in this manufacturer’s ability to make a defective dangerous car seat right. The service was awful, stressful, and all together putting my [XXX] life in danger. I’m genuinely hoping that a government agency can be my last chance of hope before I have to go out and spend another $)50 on a new car seat when I just purchased this one 18 months ago. It’s unfair and the way they are treating customers in beyond negligent. Please help! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2020 GLE 350 and today, I was turning into a parking on my right. I stopped my car, switched the cameras, so I could see the parking slot on the screen. Just when I took the right turn into the slot, the car accelerated at the same angle and jumped onto the curb. I tried hard to brake, but the brake was not working. I had the presence of mind to press the Park button on the gear lever and then the car stopped. No car damage or no injury, but it was a close call. I called 911 and the Johns Creek police helped me to get the car back in the parking lot,. A police report was not filed

While driving on the HWY the vehicle started to loose acceleration and make some strange noises. When I tried to give it gas I heard a loud pop and smoke starting coming out of the hood of the car and the exhaust.The car shut off in the middle of the hwy. With the moment left I got the car over 3 lanes to the shoulder. There were two of in the car that were at risk if this failure would have caused an accident. When I heard the car making noise and before the loud pop. I went through the cars on board computer to see if there were any maintenance messages or if the car had low oil or tire issues. All the on board messages were good and nothing indicated there was an issue. Then the pop and car shut down came suddenly. I had the car towed to a Mercedes dealership. The car is 10k over the standard 50k warranty. The Mercedes dealership indicated that a rod went through the engine the car needs a full engine replacement and new front axle. They asked me to provide them with proof of car maintenance which I did. The car was serviced regularly for oil changes and filter changes though with Mercedes parts. The manufacturer is unwilling to look if there is a defect that caused this since it is out warranty and wants the repairs paid out of pocket.

Even when new several times I was unable to start the car through the app or even physically. The self driving failed, but was repaired and about 2 months ago I got a recall notice to immediately take the vehicle , stop driving it until fixed. Feldman Motors in Bloomington MN was who I immediately contacted. The man I spoke to said simply that despite the recall the dealer would not have the parts available for at least 2 months despite the letter from Mercedes stating that they were already available. He refused to schedule an appointment. I have only that vehicle and he also refused a loaner at Mercedes expense. To date I have never been contacted again but today I got another recall notice . I simply do not know what to do except complain. Another dangerous situation happened when the powered tailgate to the SUV opens for no reason and it let to the rear contents falling on the highway. I had to stop at considerable danger to myself but Feldman motors claimed that they won’t do anything unless it happened in front of them. Simply put it happens suddenly, not all the time and I obviously cannot replicate the issue in front

A safefy recall was issued December 2023 for my vehicle. I received a recall notification letter dated February 2024. The letter stated that the fuel pump impeller mighe deform contacting the fuel pump housing causing the fuel pump to stop operating. As a result the vehicle could lose drive power and increase the risk of a crash or injury. As a result I am reluctant to drive my vehicle far from home. I'm told after nearly five months there is no remedy. Someone at the local dealership said the remedy is available but had not reach the area where I live. As a customer I am totally dissatisfied with the handling of this safety recall.

My 2022 Mercedes GLE 350 With distronic adaptive cruise control accelerates with the cruise control disabled. It's happened about a dozen times since I purchased the vehicle in September of 2022. All acceleration issues occurred at low speed while turning. Right after I release the brake while turning my car accelerates like the distronic cruise control is engaged eventhough I just braked and it's disengaged. I have to quickly hit the brakes to disengage the accelration.
