Raw fuel smell when vehicle is at idle. Breaks are very loud at low temperatures. Very squeaky like metal on metal yet the brakes are like new from Mercedes dealership.

Continuous problem with brakes squealing very loud. Have had brake pads replaced and taken to dealership multiple times to no resolution. It is a huge problem with how loud it is not to mention unsafe and making me feel uneasy about them giving out at any time. This is ongoing from several years ago

Often after starting the car, inside the car there is a gas smell that we have to closed the vents as it becomes unhealthy until the smell goes away, it last up to 10 minutes. I have taking the car to my mechanic who specializes on Mercedes and could not find any leaks and/or anything wrong. My other issue is that during the raining season when I put my foot on the breaks it makes this loud sound like an airplane landing that I have to release and press and release and press so the car will slow down. My mechanic have done multiple inspections and finds nothing wrong. My third issue is the suspension, driving on freeways at speeds over 55 mph I feel a lot of shaking between front wheels and I can feel every single bump. Again, my mechanic has found nothing wrong that even checked for recalls and has told me that there are no recalls for this vehicle. Obviously there has to be a recall issue and the one more concerning is the gas smell inside the car at start up.

Brakes screech loudly when in reverse causing noise disturbance and concern about possible safety issue. This has been an on-going problem for several months and is getting progressively worse. Apparently, this defect with brakes is well known to mercedes-benz but they have not issued a proper fix or recall for the problem. Vehicle purchased pre-owned from mercedes-benz dealership in walnut creek in 2018.

Brakes started screeching loudly when backing up startling neighbors. After seeing many reports on this same problem, I had the dealership replace the brake pads as goodwill. Screeching returned shortly thereafter and I continue to annoy neighbors. Runflat tires threads were worn out after only 10,000 requiring replacement of all 4 tires. Rear door driver's side is unable to be unlocked or opened from the inside. Driver's seat side panel covering seat belt continues to fall off exposing the seat belt drive, even after repair by dealership.

Purchased the car new from dealer in march 2016. Brakes squeal in reverse when there's cold weather. The dealer has replaced break pads and rotors 3 times but still the same issue; I've brought it in for the same problem over 4 times. The latest 'fix' was january 2018.

I purchased this SUV march 2016. A few weeks after delivery the brakes started making squeaking sound when I backed out my garage in the morning. Over the past 18 months I have taken to the dealership several times for this problem without resolution. My service adviser shawn and the service department of mercedes benz of delray have tried some fixes but all have proven to be temporary. The noise gets progressively worse after each "fix" unless I bring the vehicle back for another adjustment. Now I am concerned that there may be an underlying safety issue. With the brakes.

Mercedes benz glc300 brakes began to squeal soon after purchase. This was noticed when backing up after vehicle sat for a while, rotors and pads cool. Reported to dealer, but they did not seem concerned or mention any known problem related to glc 300 brake noise. I did not press the issue at the time as I thought it might go away after the pads were broken in. Unfortunately the problem has gotten progressively worse. Now it even squeals when going forward if you lightly apply the brakes, again this is when the pads are cool. The dealer now says that this is not a covered issue, since I have more than 10000 miles. Many references to this issue are easily found on the internet for this particular vehicle.

The brakes squeal at an incredibly high pitch when in reverse the first few times it is used every morning. The sound is painful. It has been going on since we leased the car in 6/20/2016 it has been taken in to the dealership several times for this problem...never to be fixed. It is now making the same high pitch squeal when you are braking while driving forward.
