I was told by the investigators that the fire was caused by an electrical component under the passenger seat that Mercedes is well aware of. My life was placed in danger because of the Inhalation of forever chemicals and lung damaging smoke and super heated air. Problem confirmed by dozens of owners who experienced and documented the very some accounts, some who have reported contacting the NHTSA years prior to my experience but nothing was done to save lives or prevent losses. The American Freedom insurance investigator told me in writing what caused the fire. Nothing gave any indication that my life was in danger not a light, an alarm nor the monthly Connect service I paid for every…

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…

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…

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…

While driving at 65 mph on Floridaâs 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…
