2020 MERCEDES BENZ GLC 300 Unknown Or Other Problems

The front main light on the driver side stopped working after a rain and it continued getting moister in the head lamp every night until a few days ago and as a result the head light assembly does not work at all ,the same thing is happening on the passenger side front head light assembly except it is still working .research showed that this has been a problem on similar Mercedes Benz cars and considering that the car has not had any accidents to possibly causing this it was concluded that this should have been part of the recalls .car is not operatable and i reached out to Mercedes Benz and they acted like I am out of my mind and it is passed the express warranties with car having 69000 miles. I tried explaining to them about the implied warranty and the safety problem and they continued with the same none sense. at this point The MBZ dealers want over $ 6000.00 to replace the part and I am not able to operate car.what can you do for me and others effected.

While driving on the highway I began to hear an unusual amount of wind noise inside the car. I thought the sound was coming from the sunroof, though it was completely closed. I pushed the button to confirm it was sealed, but the noise continued. Shortly after, I heard a loud cracking sound followed by a sudden pop. I looked in my rearview and saw something flying but didn’t immediately recognize what it was. I pulled over to inspect the situation and discovered that the entire exterior trim panel between the windshield and sunroof had detached. Another driver, who had been behind me, also pulled over after being struck by the debris. Thankfully, there were no bodily injuries, but this incident could have resulted in a serious accident. A large, fast-moving piece of trim flying off a vehicle at highway speeds presents a significant danger to other drivers, especially if they try to swerve to avoid it. I took my car to a Mercedes-Benz dealership for inspection and potential repair. I informed the service advisor that I had seen documentation of a recall involving the same issue, detachment of the sunroof panel on vehicles of the same make, model, and year as mine. However, I was told that my vehicle was not eligible for the recall based solely on its VIN and that Mercedes would not cover the cost of repairs. This is not a typical wear-and-tear issue. Structural components of a car should not randomly detach, especially on a vehicle that is only 5 years old and has been properly maintained. It is extremely concerning and, in my opinion, negligent for Mercedes-Benz to be aware of this defect and yet fail to extend the recall to all affected. The advisor acknowledged this issue was likely due to a problem with the adhesive used to secure the panel, something he said he had seen happen on other vehicles. Despite this, I was told I would be fully responsible for the repair costs. There were no warnings or signs this would this happen, the panel detached suddenly.

Dear Sirs: I own a 2020 GLC300W Mercedes SUV. As of this date, It has stalled 5 times while driving on the highway and on the roads within an 8 month period. Throughout this period, I have taken the vehicle to the Mercedes dealership in Riverside, CA three times to have this inspected. After their first inspection, the dealership claimed that the problem was due to a recall on a computer software update needed. However, the vehicle stalled two more times while driving on the highway. After the second inspection, the dealership claimed the problem was due to a bad throttle actuator and charged me $2000 for the repair. Two months later, the vehicle stalled on the road once again. Currently, the dealership is inspecting the vehicle for a THIRD time. I have viewed your NHTS website and came across NHTSA campaign number: 23V445, Problem Description: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2021-2023 C-Class, E-Class, S-Class, CLS, SL, GT, GLC, GLE, GLS, and G-Class vehicles. Please refer to MBUSA's recall report for specific vehicle details. The fuel pump may shutdown, which can result in a loss of drive power." I believe this is the cause of my 2020 Mercedes doing the exact same thing, however the 2020 model is not listed in this recall. Please investigate this as this may be fuel pump issue applies to 2020 models.

The rear camera system becomes inoperable when car is first started and put in reverse, then all cameras remain interoperable while driving until sometime later after the car is turned off. This problem occurs intermittently. The symptoms match those described in Mercedes recall campaign 22S20, NHTSA Campaign 22V232. The recall names Mercedes Benz GLC300 but my vehicle’s VIN number does not appear in that campaign. Can it be added?

On Saturday October 5th at roughly 8:30 p.m. heading West on I-94 near battle creek, MI, the glass sunroof on our Mercedes suddenly exploded out and shattered. We were traveling at 75 mph with little surrounding traffic and no over-head obstructions. It took a second to re-gain control of the situation and slow down to a stop. We had the sun-shade closed, saving us from glass shards raining down from the exploded sunroof. The following Monday morning, Oct 7th around 9:00 a.m., we called Mercedes about the issue. They were indifferent and offered no assistance. They pointed out that our MY2020 with 29,711 miles on the odo was not covered under warranty for the sunroof shattering and that we would have to deal with our insurance company. They also informed us that they would not have any rental cars available during a repair until at least December. We mentioned that there was signs on the internet of class-actions against Mercedes for similar sunglass explosions to which they quickly responded with - not on MY20 300 GLC. We did get the sunroof replaced through our insurance. Anecdotely, when we took it into the glass repair shop, they had just did another one, similar situation the week before. This could have been tragic. Glass shards could have been everywhere. The only reason the sunscreen was deployed was that we had our baby granddaughter in the car only 1 hour earlier. Otherwise, that screen would have been open and the glass would have rained down on everyone in the car.

I have had issues with squeaky, very loud noises at slow speed and reverse braking. I have had this issue since I purchased this vehicle. I have brought it in a few times to have 2 different dealers fix the noise as I believe it is a safety issue as well. They said this is a common issue with GLC that they have noises while braking but there is no fix. I had an advisor drive the vehicle and witness loud squeaky noises while braking. Spending a lot of money on this vehicle, and Mercedes should fix this issue. I believe the brake system falls under lemon law and Mercedes should do something to mitigate the issue. The brake pads were okay upon inspection, but pretty soon I will have to pay a lot of money to replace pads at my own expense when the brakes, pads, rotors, etc themselves should be replaced and fixed at Mercedes expense.

Sunroof stopped working, no longer sits flush with vehicle, will not open. I’ve seen recalls for other models/years regarding unsafe sunroof, potential of detaching sunroof. I believe my vehicle should be included in this recall as well.

There is a squeaky noise from the suspension, shock absorbers or somewhere in that area. They have fixed the issue multiple times. Kept my car in the workshop for days multiple times but it’s not getting fixed. They probably sold me a lemon. I need help in rectifying this issue.

The manufacturer service dealer (Mercedes) has been unable to clear a VIN recall notice, even though they say it has been updated. The system still says it's recall. They have had the vehicle for almost 30 days, and have not been able to fix the issue. The recall is for a software update, and the dealer says they've done everything at Mercedes of Ft Lauderdale, and the Manufacturer, (Mercedes) says it's the dealer problem. The dealer says its Mercedes problem, and we as the customer are stuck in the middle and have no car

I have received recall notice 3 months ago for software update. The update was supposed to happen over the air which it didn't. I need this update to finish asap because i need a recall clearance letter. This update took way too longer than it should have. Please solve this issue for me. Regards,

Manufacturer Recall Number2021060021 NHTSA Recall Number21V354 Mercedes dealership said they're unable to complete this recall, and it must be done via OTA update. Vehicle has no OTA update available, Mercedes refused to push update when requested, and could provide no information on when an OTA update would be available.

I WAS DRIVING AND STOPPED CAR TO MAKE A TURN WAITING FOR INCOMING TRAFFIC TO CLEAR. WHEN I WENT TO ACCELERATE AFTER TRAFFIC CLEARED, THE CAR WOULD NOT GO ABOVE 0.5 MILES PER HOUR. I MADE SURE THE GEAR HAD NOT SHIFTED TO NEUTRAL, IT WAS ON COMFORT DRIVE. I CHANGED TO SPORTS DRIVE AND THE CAR STILL WOULD NOT ACCELERATE ABOVE 0.5 MILES. I WAS NOW STUCK IN THE MIDDLE OF INTERSECTION WITH INCOMING TRAFFIC, SO I TRIED TO REVERSE. THE CAR REVERSED NO FASTER THAN 0.5 MILES PER HOUR. I TURNED CAR OFF AND BACK ON, AND ACCELERATION THEN WORKED. VERY SCARY. I WAS LUCKY INCOMING TRAFFIC AVOIDED ME. BIG SAFETY HAZARD. DEALERSHIP SO FAR HAS NOT BEEN ABLE TO REPLICATE THE ISSUE, BUT I READ OTHER BLOGS WHERE PEOPLE EXPERIENCED A SIMILAR EVENT.

THE AUDIBLE TIC-TOK SOUND OF THE TURN SIGNAL IS WAY TOO SOFT. THE SOUND IS SUPPOSED TO GIVE ONE NOTICE THAT THE TURN SIGNAL IS ON. IT SIMPLY ISN'T LOUD ENOUGH TO PROVIDE THAT FEEDBACK. CONSEQUENTLY I OFTEN FIND THAT I'M DRIVING DOWN THE STREET HAVING COMPLETED A HALF-TURN ( ONE WHERE IT DOESN'T TRIGGER A SHUT OFF) WITH MY TURN SIGNAL ON FOR BLOCKS BEFORE I NOTICE THAT THE TURN BLINKER IS STILL ON.
