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

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).

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.

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.

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.

Quickest Breakdown Ever

I purchased a new 2024 Mercedes GLS 450 over two weeks ago from a local dealer. Drove it 2 miles and the engine warning light and the hybrid/starter/generator light both came on. The manual said take to the "work shop" so I took it right back to the dealers service department. The engine warning was faulty air intake manifold which requires parts from Mercedes and they don't have them all. The hybrid issue can't be assessed because the car won't start until the manifold's repaired. No idea when the car will be fixed. If I had it to do over again, I'd steer clear of a Mercedes Benz. Buyer beware...
Best SUV we've Owned

This is our third GLS (2009 GL450 and 2017 GLS450 prior) and it is by far the best one. Our 2017 GLS was terrific, but the 2022 is built like a bank vault. It's better in almost every way. The ride quality is superb, its interior is serene, and the emerald green paint is gorgeous. A few small complaints - some physical buttons/controls are inconveniently located; the infotainment system is too complex; wireless Apple CarPlay should be available in all vehicles by now, especially at this price point. This is my wife's vehicle, but I love to drive it every chance I get. We are both happy with this purchase.

GLS 450: The only good thing is stability and comfort. But feels like driving a very heavy vehicle. Poor electronics. I have a Toyota Highlander it has 200% better electronics than this 2023 GLS450. Yesterday, suddenly, while I was driving on a highway, got a battery warring flash, after a few minutes’ vehicle was stopped, could not restart for 30 minutes. This incident completely broke my confidence on this vehicle. I have invested $100k on this vehicle. This new car has only 3500 miles on it so far. We have BMW X5, compared to this BMW, it’s completely worthless to invest on this model, probably on this brand: Benz. I have big doubts about the reliability of this vehicle.

We splurged on the AMG and sort of (yes) regret it. It changed some of the features we didn’t know it would until we got it and drove it. NO cup holders in the second row. AC unit is confusing and seems to not work properly. I’ll have my ac on full blast and on sync for the rest of the car, and my daughters backseat isn’t getting any air. The auto crash sensors would go off for no reason scaring the hell out of me. The service dept would have it for weeks and then just say they updated the OS. Ugh and I wish I would have gotten capitans chairs but that’s on me lol

This is my first Mercedes Benz. I’ve been a BMW fan for 10 years and still enjoy the sportiness it delivers compared to other brands. I contemplated an X7 and a GMC Denali prior to purchasing a GLS. Extremely satisfied with the purchase. Very comfortable vehicle, technology is what you would expect for the money. Versatile and roomy. Not disappointed. I do miss the sport feeling of my previous Bmw X6M but I was ready for a more comfortable ride. Hope this helps. Certainly not disappointed just a different stage of life.

I love almost everything about this SUV but only had it for about 4 months. I bought CPO with 3k miles so practically brand new. Sticker was 87k, has a few extras like 21in wheels. I love the quality, luxury and driveability, this SUV is more like a european sedan the way it drives. The tech can be a bit annoying as there is so much of it and some features maybe hard to find but I'll hold off any critique as still learning how to navigate and what I like. The Navigation is pretty good with the live traffic option but clearly the mapping is not up to date even though I have automatic updates enabled. The GLS has plenty of room for a full load of people (7) and all loaded up still handles like a dream, and I have been routinely getting 24+ mpg. I would recommend this model to anyone who is looking at this class SUV as it is very refined without having unnecessary bells and whistles.

Purchased new 2024 GLS 450. The ride was outstanding with really comfortable seats. The GLS has one of the best 3rd row seats available for space without being an enormous vehicle. The nav is better, the cameras are out of this world and all of the tech seems to work better. We couldn’t be happier to be back in a GLS and Mercedes has really outdone themselves with this SUV.

Moved. Drove from Texas to Maine, from flat lands through the Appalachians along the way. The car was packed,except for a narrow slit to see out the back, and all back seats folded down. Quite a bit of weight, though we did not trailer or carry anything on the roof. Few vehicles remain enjoyable rides like this, but the GLS 450 was a champ. Road-ability solid, driving comfort exceptional, noise-level low, low, low....and visibility in heavy truck traffic made for a safer trip. Nothing phases this SUV, with lots of horsepower to sustain speeds on long grades. This is my third Mercedes; having owned an E320, 350ML, and now this one. Bigger is better for long drives. I will always own a GLS as long as available. Cost maybe high, but money is relative when you're driving long distance road trips.

I just purchased a 2022 GLS 450 and absolutely love everything about the car. Two months prior to the purchase I paid $2600 for pre-paid maintenance which I had not yet used and Mercedes USA refused to refund. My local dealer did reimburse me 80% of the cost, but I'm still extremely disappointed that Mercedes kept the entire amount I paid. Not what you'd expect when I have purchased 2 brand new Mercedes in 2 months totaling $180,000. My vehicle and dealership get 5 stars, Mercedes Benz USA 1 star.

Love the GLS. Great ride and performance is amazing. Only question is the driver assist package, don’t like it for driving in the mountains as it slows the car down for some corners and the lane keep is off for a twisting two lane road. The technology is almost too good. It is a great SUV and fun to drive

"Bennie" as my wife calls our 2024 GLS580 is everything you could ask for in an SUV. We've driven a little over 15K miles in the first year. The GLS is extremely comfortable, both in town and on the road. The 500 hp is probably not needed, but truly appreciated. Overall quality is excellent, just what we expect from M-B. The only negative are the stock tires in winter driving conditions, as evidenced on our first outing on an icy road. There is a very limited selection available in winter tires, especially with the front and rear wheels being of different sizes. A four pack of Blizzak tires on a set of aftermarket rims gave the GLS the traction it deserves. This one negative aside, we are very impressed and satisfied with our 2024 GLS580. Highly Recommend
