2024 Mercedes-Benz GLS 450 consumer reviews

I’ve had nothing but frustration with my 2024 Mercedes GLS 480, and I feel obligated to warn other potential buyers. Since purchasing the car, I've had to bring it in 7 times for repairs, spending a total of 43 days in the shop within a few month period. The primary issue has been the transmission, with the car continuously shifting hard between gears, jerking while driving, and failing to shift smoothly. Despite multiple attempts to fix it—including discussing replacing the engine and transmission mounts, performing downshift adaptations, and following Mercedes-Benz’s TIPS instructions—the problem persists. What’s even worse is that after paying nearly $100,000 for this car, it's lost significant value without any resolution to the problems. I can’t help but feel I’ve thrown away my money on a car that constantly requires service with no lasting fix. As if the transmission issues weren't enough, the lack of basic features is also frustrating. I was shocked to find out that my car doesn't even have remote start on the key fob—something I expected, especially for the price. Instead, I’m forced to pay even more for a yearly subscription to an app to use this basic function. Why does a car that costs as much as mine not come with this simple convenience? To make matters worse, Mercedes-Benz refused my buyback request under my state’s lemon laws. After months of service visits and communication with customer care, I was told my case didn’t qualify, and I was left with no option but to continue bringing it back to the dealership for repairs. It’s incredibly frustrating to keep hearing that “we’ll fix it” when nothing actually gets fixed. This experience has been a huge disappointment, and I would strongly advise anyone considering a Mercedes-Benz to think twice. I’m stuck with a car that doesn’t work properly, lacks basic features, and has lost substantial value. For $100,000, I expected a luxury vehicle that at least functions as advertised.

My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.
