We purchased a 2024 GLS 450 six months ago. There is wind noise while driving that sounds like a swarm of bees in the headliner, the transmission is very jerky on downshifts (it feels like you have spiked the brake), the check surrounding sensors go off all the time in traffic, the lane assist sees tar strips and old line paint in construction zones and wants to force you into other lanes or the old non existent roadway, the seat settings and temperature control settings do not stay programmed when you turn off the SUV. All of these items are annoying and some are safety issues. What does Mercedes say? The SUV is performing as engineered, this is Mercedes Quality. This is the most disappointing $105,000 vehicle there is and the dealer is not interested in fixing it.

Transmission Blew Out in 12 Months

I should have heeded the advise of a colleague who warned about serious quality issues with Mercedes brand. Transmission of my new 2023 GLS blew out completely without any warnings in exactly 12 months, leaving me and my wife stranded in the middle of a busy street. They had to order a new transmission and took a total of 3 weeks to get the car back. While it didn't cost anything out of pocket thanks to factory warranty, this is not what I had expected from a $100k MB which at one point used to be synonymous with "high quality and reliability". I am going back to BMWs (I have owned 3 of them for a total of 15+ years) or Audi (owned 1, for a total of 6 years).

Do NOT buy a GLS450 - The Worst!!!

The GLS450 2023 just suddenly stalls while driving - loses all power - they don't know how to fix. It stalled out twice on consecutive days in first week of ownership! Nearly killed us - going to try BMW X7. We had a previous 2020 GLS450 that did the same thing 10-12 times a year and they never were able to fix it. The GLS is still the worst and most dangerous SUV’s we have ever owned! The 2024 BMW X7 is amazing - smooth, quiet, reliable, powerful and amazing gas mileage (surprisingly) averaging 27mpg! - if you drive or try a new X7 you will never consider a Mercedes again for a SUV

It's a nice car but it's not perfect.

The gls 450 is slow to pick up speed from a stop. It's quite noisy on uneven surface. It's bouncy on bumpy roads. Lot of tire noise coming into the cabin. The only time I get to enjoy the car is when it is on a smooth road.

Been driving my GLS for a little over a year now. 20,000 miles My first comment is, wow! Did not think the V6 in my 2018 was lacking until I got the V8 in the 580. Truly impressive acceleration. Just had a GLE for a loaner and yeah, the acceleration is real. The real reason I prefer the GLS is the ride. For a vehicle with nearly 7500 lb GVWR it rides marvelously. The road noise and engine noise is minimal. I prefer the GLS450 interior to the 580, but the quality is great on both. At highway speeds of 80 mph averaged 23 MPG. MB marginally improved their tech, but it is still significantly lacking given the price point. CRAZY THAT ANDROID AUTO MUST BE WIRED. MY LOANER GLE HAD WIRELESS ANDROID AUTO AND IT WAS GOOD, SHAME MB DOES NOT THINK IT IS NEEDED ON THEIR HIGH END PLATFORM WHY HAVE A WIRELESS CHARGER THEN HAVE TO PLUG IT IN TO USE ANDROID AUTO, IT IS ACTUALLY EMBARRASSING. Touch screens and finally a real use for the mouse pad. When driving the touch screen is a reach, I'm 6'1", and the pad does allow for easy swiping. The learning curve is real, and takes time to find things, but overall it very customizable. Tech start up is painfully slow, sometimes taking close to 30 seconds for the system to boot up. JUST GOT NOTICE THAT I HAVE TO PAY FOR THEIR HALF ASSED APP TO START AND LOCK MY CAR! NOT THAT $15 / MONTH IS A WORRY BUT TO EXTORT ME TO USE AN APP THAT ONLY WORKS OCCASSIONALLY IS RIDICULOUS. HAVING TO PAY TO REMOTE START OR LOCK YOU VEHICLE IS BUSH LEAGUE, THE CAR WAS $100K+. My only complaint on the drive side, and it is enough to tell anyone to take a highway drive before you buy, the lane keeping system is jarring to the point of sickening. If you stay left while passing a vehicle or missing an object in the road it will throw you back into what you were avoiding. You cannot turn off the lane tracking without turning off the warning as well. So, in Germanic fashion, we know better than you, you will use the car the way we say is best, even if you have good reason. If one could keep the warning and drop the harsh lane correction it would be great. The cruise is no longer a speed keeping system, it is an auto drive system. I personally have issue giving control to the machine, and there are times when I would like to drive the car. I was exhausted after my first trip fighting the car and how it liked to drive over how I like to drive. Drive 800 miles over holiday and kept cruise off most of the time because it is actually more work to use the cruise than not. Seems cool at first but if you use cruise a lot I would look carefully at how cruise has changed. One thing that I do find odd is you cannot lift the drivers windshield wiper to clean under it, or wipe things off the blade, without hitting the hood and stopping it. I'm not sure how you would change wiper blades like this. New issue that I found is if you are an aggressive driver, guilty as charged, the collision avoidance system is so sensitive it is almost dangerous. My car stopped me in an opposing lane thinking I was going to crash which almost caused a crash. I hate to turn it off because I can see the value but it it needs refinement. Maybe the car is just smarter than me, and as much as I hate the lane system, the car is a great ride, but don't expect much from the tech.
