4.74 Stars, Almost perfect, but...
Jay Poocha, 03/22/2021
2021 Mercedes-Benz GLS-Class GLS 450 4MATIC 4dr SUV AWD (3.0L 6cyl Turbo gas/electric mild hybrid 9A)
Over the years, we have owned many Luxury SUVS and a few mini-vans. We purchased a 2021 GLS 450 in early November 2020. As of today, we have driven 25,402 miles! That's not a typo. In a very short period of time, we have discovered the strengths and weaknesses of the GLS. The strengths: 1. Overall comfort, especially the front seats, is awesome. 2. The added massaging seats is a nice … option (get it, you won't be disappointed on long trips). 3. The ride is smooth on the highway and around town; however, I prefer to use the individualized setting option for the sports suspension on the highway to firm up the ride, otherwise it can be a tad floaty. I prefer a stiffer, more controlled ride. 4. Passing is done with ease at speed; however the 450 holds gears a bit long when rapidly accelerating. It eventually finds its place after a brief struggle. Not bad, but not perfect.
After driving 25K in a very short period of time, I would like MB to strongly consider improving a few areas in the cabin: 1. The cell phone ports (only usb c type) must be better placed. They are extremely difficult to plug cords into, plus need some type of ambient lighting to see at night. The wireless charging pad is a pain in the rear to use with a case on a telephone. The space is extremely tight. This must be corrected at some point. The power outlet in the second row is horribly placed. In fact, MB get a F- for its placement, and another F for the amount of space allocated for any charging bases larger than standard size. Just the worst of anything we have ever owned. Outside of these minor issues, my wife wishes MB would add a place for cellphones besides the cupholders or wireless charger area. This is an obvious deign oversight. Second row comfort in the captain's chairs is good, but I would strongly considering getting it with the bench in the future for the center armrest. Although the captain's seats are comfortable, again MB needs to add more places for storage.
The third row works for smaller adults and children. We occasionally use it, it works for the occasional trip when are children are traveling with us. The real trick is placement of luggage; three suitcases and a duffle is tight - this requires folding one of the third row seats flat. Although not ideal, it works. For ultimate convenience, I would suggest either a Cadillac ESV or, bite my tongue - a fully loaded Chrysler Pacifica. Having owned both these other vehicles, I can say luggage space is rarely an issue.
This leads me to my final thoughts on the GLS, I really like it a lot, its almost perfect except for the few issues I outlined. If MB can address the charging issues, phone placement issues and tweak the trans on shifting on the middle range when accelerating, it is hands down a superior SUV for long trips, daily comfort and drivability around town. It feels rock sold on the highway and does extremely well in rain. If you desire luxury, a very solid feeling ride, solid handling and decent MPG (I'm averaging about 23 MPG) I highly recommend the GLS.
