Loud road noise and rides rough

Incredibly loud road noise and rough riding and only has 2,500 miles. After a 2 hour drive, my ears are ringing. I would not purchase again, Mercedes has let me down


Battery dead every night on glc300

I owned a 2021 Mercedes glc300 loaded one. I owned it for about 8 months. I had it at the dealership more than I had it. I finally got it working but I guess not they still had trouble with it. I've heard from doing research the problem is with the radio takin to much battery and the radio running after the suv is off. The problem I had was the battery kept dieing. Some people say pull the fuse at night for the radio and see if that helps. Or keep a battery tender on at night! I put a new battery in the car didn't help


A Surprise Flop

This is my third car in this class. Mercedes has always been my favorite car and I have always loved my cars. Unfortunately, I just traded in my 2019, which I really wanted to keep, but the dealer wanted to charge me $4000 above my buyout price, to "certify" my own car. For me, this is a scam to get you to say, no way, and they get to keep the car, certify preown it, and make tons of money off the car. Of course I told them I will not do that, and proceeded to buy a left over 2021, with 12,000 miles on it. I thought nothing of it, and was excited they had a car for me. Well I purchased it on 5/21, it was back at the dealer all of memorial day weekend, got it back that tuesday, and was back at the dealer that Friday. I have not seen it since. The trouble was with the Blind Assist, and some electrical things. They tried upgrading it, and replacing a board or something, and they are doing it again this week. They have to confer with Mercedes to see what to do. I hate to write a terrible review, but this has been my experience thus far.
