I was parked for a few minutes and I suddenly noticed a strong oder coming into my vehicle. I could not pinpoint what the smell was, but I knew that whatever was coming into the SUV was not safe. My screen started flashing warnings "Service Required: Do Not Drive" âDo Not Shift Gearsâ. After the warning, white smoke started to roll out from under the hood and into the vehicle. I immediately ran back to get my baby out of her car seat and to safety. I was at my local YMCA and staff ran out to I assist me and had a fire extinguisher. YMCA called the police and fire department. Both were dispatched to the scene. I called my husband for help while we waited for police & fire to arrive. My…

I bought a 2026 GLC300 4matic SUV a month ago. I am very disappointed and scared of serious bodily damage due to the trunk door closing by itself while my upper body is loading/unloading the trunk. My wife and I were hit on the shoulder, back, arms, or head over a dozen times for 1 month. We took the car to the dealership for the problem but did not hear back from them for 3 days. The loaner car the dealership provided which is also 2026 GLC300 SUV also closes on me in the trunk. When the trunk shuts by tself while part of my upper body is in the trunk, it is impossible for me to stop it. It requires the 2nd person to stop the trunk door by forcefully pushing up. If I am alone, I don't know…

Service brakes
The breaks on these vehicles are extremely dangerous . Before I leased this vehicle test drove 3 vehicles. The salesman said the breaks will adjust as you drive. They have not. ITS all over the internet that this vehicle has very unresponsive breaks. It takes 75 precent of pressure pushing down on the break pad distance before the car breaks engage. I already almost had an accident as the distance it takes for the car to respond is a significant distance before the car comes to a full stop. I have brought back the car to my dealership three times expressing my displeasure and each time I m told there is nothing they can do unless a fix comes from the manufacture. They said I'm not the first…

Power train
While at a stop with foot on brake, the vehicle surges forward powerfully making a loud noise despite having foot on brake. Forcefully pushing on brake pedal harder eventually stops the car. Most recent time the display screen showed "Transmission Deactivated". Dealership drove car once but did not perform service inspection. Dealership to pick up/tow vehicle for service inspection. This happened four times in the eight weeks since pick up of vehicle as brand new. This could have cause a crash or caused vehicle to strike an object or person. Vehicle accelerated on its own and was difficult to stop.
