Welcome to the forum. Not sure about the costs for a GLE53 as I have the GLE63s, but as with any costlier car, maintenance at the dealership will be more expensive. I've only had my car 6 months and so far I've only done an oil change along with the air filters. I've heard the cars can go through tires pretty quickly along with brakes. For me the extra costs are worth it as these are amazing cars to drive. I enjoy each and every drive in my car!!

My 2021 GLE 63S was due for its annual service after 2 years. I called two dealers in Denver. Both quoted around $1,150. I was told by a neighbor who used to work for Mercedes that the front pads & rotors for that SUV are about $3K. Looking at the tires, I'm figuring they'll be good for about 15K miles.

Each maintenance item is “a couple hundred bucks”. Dealer labor is in the upper $100s to near $200 per hour depending on city/region.

oil change couple hundred $ every 10k miles
engine air filter $100-$200 every 50k miles
brake fluid replacement couple hundred $ every two years
cabin filter $100-$200 every two years
brake pads and rotors $1500-$2000 every 1-3 years depending on driving style
tires $2000 every 1-3 years depending on driving style
spark plugs $600-$1000 every 50k or 60k miles


DIY or Indy shop are two ways to save money on these things.
