We recently bought a 2021 GLS 450. The warning systems work some of the time, but not consistently. We had all the driver assist features malfunction so into the dealer. They found a severed sensor wire which Mercedes said normally wouldn't be covered (The car had 1800 miles on it), but they decided to cover it anyway. Sometimes we get an audible parking assist warning sometimes we don't. My wife managed to back it into another car and never got a warning. I understand it was her fault for relying on the back up warnings, but it is so unreliable that it is really useless. We have had multiple cars with parking assist and never had any problems. It was inspected after the fender bender by the dealer , but they couldn't find any issues. They gave us Mercedes Benz USA contact info. We have collected multiple videos of the system not working to show the Mercedes rep. When we called MB USA, they were confused as to why we were calling them and told us that there are plenty of warnings not to trust the system. Great! Does that mean we shouldn't trust the adaptive cruise or any of the lane assist features? What is the point of having these systems if they don't work. Add in to those issues the incredibly loud drivetrain (also checked by dealer, but told it was normal due to high pressure system like a diesel), I can't recommend this car. It's nice when it works, but no better than competing vehicles. Stay away.

Purchased new 2021 GLS 450 $92000, the SUV is in the shop more than in my garage. Major computer dash problems. After 4 attempts, they can’t solve the problems. MY SUGGESTION!! Stay away from the GLS 450 SUV.

Great Ride Terrible Tech.

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.

12th time in the shop in 10 months since purchase

I bought a 2021 GLS 63 on 1/2/2021. Within 48 hours they sensors misfired and the car was at the service center. It took them 4 tries to fix it with the last try taking them 28 days. I got the car back and the brakes began sounding. It took 7 tries at the service center and they can’t get it right. Today the car stopped working entirely and though the battery functions worked the started wouldn’t kick in. It’s my 2nd tow, 12th service and I will never drive it again. Lemon law all the way.

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.
