There is an active recall for my vehicle Mercedez Benz GLC 300W4 for which I was NOT NOTIFIED BY THE DEALER AND MANUFACTURER. The recall states that certain 80A fuses installed might not meet production requirements. As a result, a contact interruption or an increased triggering resistance might occur. In this case, systems connected to the fuse might become inoperable. Among others, the vehicle might lose propulsion without warning, restraint functions or the instrument cluster might be impaired, increasing the risk of a crash and injuries. In addition, a risk of fire cannot be ruled out. An authorized Mercedes-Benz dealer will replace the respective main fuse box on the affected vehicles. The following is the SAFETY RISK associated with this recall. As a result, a contact interruption or an increased triggering resistance might occur. In this case, systems connected to the fuse might become inoperable. Among others, the vehicle might lose propulsion without warning, restraint functions or the instrument cluster might be impaired, increasing the risk of a crash and injuries. In addition, a risk of fire cannot be ruled out. I have noticed that check engine light turning on at times while driving which might be due to this fuse malfunctioning. Please take appropriate action and support my case. I can provide more details if required. Thank you.

First of all, this is a new car produced in 2023. Since I bought it, the engine has shown alarms more than four times. Every time I went to the 4S shop, no problems were found. Today, the engine still shows a yellow alarm. Secondly, the brake disc makes a loud noise when I park the car and then start the accelerator. Mercedes-Benz has not paid attention to these problems. I think it greatly affects driving safety.This car has been sent to the 4S store many times, but the inspection has always failed. The above-mentioned problems with the car have always existed. I sincerely request your help in solving them.

The automatic windows open when the car is parked without being initiated by anyone. Think of it as phantom window opening. The vehicle occasionally reports a window being open when in fact they are all closed. When the phantom opening occurs there is not notice of a window being open.

When working in the rear cargo area, the door comes down without warning and does not break when it meets resistance trapping me between the body of the car and the descending door. A great deal of physical pressure must be employed in trying to get it to reverse direction. It is a struggle to get out from under the continually closing door. This has happend to me on three different occasions. There should be an automatic reversal when the door meets resistance not unlike a garage door.

On [XXX], I was driving at 45MPH on a two-lane state road. There was no traffic within 1/4 -1/2 mile of me on that road. There were no guardrails and the road was clear - no birds, animals, people, or construction. For no reason, the car beeped twice and automatically slammed on the brakes so forceful that everything on a seat landed on the floor. Had there been a vehicle behind me, they would have almost certainly slammed into me. This is my second safety report with this vehicle, the previously reported lane keeping assist still allows me to depart my lane with no correction or indication by the system, the dashboard indicators remain green if I depart my lane without a turn signal. It has been in 5 times for this and Mercedes closed the case. They say it's fine. Lemon law attorneys in my state refuse to take cases with Mercedes so I am stuck with a vehicle that should not be allowed on US roads, can't lemon law it and can't sell it or trade it in with a clear conscience. There is a laundry list of other problems as I drive more than 25,000 miles a year but I only report those which could get myself or others killed.
