I have a GLE400D which I bought new from Mercedes Maidstone in November 2019. The car had brakes noise after 9 months and was back and forth to the workshop but upon my insistence they changed the brake pads and the noise went. The car has now developed air conditioning issues and is back at the workshop since last Thursday and they are still repairing it!!. I have written to Mercedes in Holland and asked for their comments as the car is not meeting its price tag so far. I am very disappointed!

What the ****? And the car is only a year old... so sorry for u
My 2020 GLS 450 had air problems from the very beginning. Randomly, air would stop blowing out of the front vents. If we adjusted the fan speed, air flow would temporarily resume. You could hear the air blowing under the dash, but an internal damper had blocked the vents. The odd thing was that if I made a Bluetooth phone call, the problem would correct itself until the call ended. My car was in the shop so many times, the dealer replaced my vehicle with a new one. This one is doing the same thing. The latest answer is that there is one blower that services both the first and second rows. They said there are too many vents, and it can’t blow in both rows at the same time. They said this is by design and is not a flaw. It told them this is unacceptable. If my 1998 Ford Explorer could independently control air in the first and second rows, Mercedes needs to figure it out. I’m so frustrated that I’m considering trading the car.

Hi. The problem is the electric motors of the flaps and the flaps themselves, the flaps are loose, everything is made in a very poor way. I am working on the 2020 GLE with a mileage of 9,500 miles, before sale we do the final test, in the final test I found 4 faulty flap actuator motors. I exchanged for a new 4 that I had defective in the test, every time I install a new one, we adapt the new motors with the tester, I returned the car to its original condition, I did the final test and got a fault from another electric motor right rear fotwell. What Mercedes did is a real embarrassment, we'll see what they do with it, in my opinion it need to replace everything with better developed ones.
When my air conditioner fan starts making too much noise and interrupts the music, which I usually listen to very quietly while driving, I immediately know there is some breakdown in the air conditioner.
When my air conditioner fan starts making too much noise and interrupts the music, which I usually listen to very quietly while driving, I immediately know there is some breakdown in the air conditioner. I often turn on a soft breeze to blow in my face in the winter because I hate sweat. The air conditioner doesn't have to blow cool air in the winter. When I bought the car, I used it that way in the winter. When summer came, I realized that the air conditioner wasn't doing an excellent job of cooling the car's interior. Then I went to ac repair st pete to have the air conditioner checked. It turned out that there had been some breakdown there a long time ago. You should check your conditioner.
I've got the same car from 2020, and my AC has constant problems as well. I read somewhere that the most common causes that hinder normal operation of the air conditioning system on any Mercedes GLE450 are dirty cabin air filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, bad blower motor, defective compressor, faulty blend door actuator or any fault in the electrical system. I went to an auto repair service I found thanks to https://autoleap.com, and they told me that my problem was my bad blower motor. You cannot repair a broken blower motor, so you must replace the part with a new one if that's your problem as well.
