Compact SUV with Third Row and Modern Interior

Purchased the 2021 GLB because I was looking for a compact-sized SUV with third row seating for kids. The GLB also has a modern interior, I like the turbine-style air vents and the "surfboard" infotainment and instrument cluster. Despite what others have said about navigating the infotainment, I don't find it hard or cumbersome to use. However, one nuisance is having to scroll to the radio presets every now and then on the instrument display, sometimes it doesn't save the last setting. I also like the large panoramic sunroof although that's a $1500 option. The engine is peppy and the car is nimble (for an SUV) and has great class gas mileage. There are a few annoyances though: 1) The 2nd row seats don't fold all the way down IF the seats are moved to the front most position (the headrest hits the front seats), this makes it even more difficult to climb into the 3rd row; 2) Android Auto and Apply Carplay doesn't take up the full 10.25 inch infotainment screen, Google Maps only displays 7 inches. Hopefully Mercedes will update it to fill the screen. The GLB isn't very stylish, isn't very fast and performance-oriented, and it's not the most luxurious Mercedes; however it offers the perfect practicality. The only competitor is the Discovery Sport which is also a compact, luxury SUV with a third row.

18 months on - A great ride with a cautionary tale

A follow up to my earlier review "A nice blend of space, tech and value". Had this car for 18 months now - finished the first service. All the key points are very valid. The car offers exceptional space for a small SUV, easy to handle, great tech, super boot space. One nagging issue from the start was poor gas mileage. Right from the time we took possession of the car in 2021, we never got close to the advertised gas mileage. I asked about that in the first service check and got no response from the dealer except everything was ok. A few months past first service, the engine light came on and stayed on. We didnt take the car in immediately and suddenly found ourselves with an unreliable engine that died on. On taking it in for service, the CSR immediately mentioned that some GLB engines had faulty engines with leaking cylinders. They took the car in and replaced the engine cylinders as it was within warranty. Since then the mileage is exactly as advertised and the car performance is great. Moral of the story - if you GLB isnt giving you good mileage - get your engine cylinders checked,

As with any family, with an additional kid we had to upgrade from my coupe. We were searching for a SUV that had space for kids and a dog, provided the latest tech and was efficient enough for California gas prices. After doing a month of research, the GLB fit the badge very well. We liked the look and the interior tech. We have had it for a month now. The mileage is as advertised. Not the most performance oriented engine but it can be zippy enough. We got parking assist which is really for city driving and parking. Music system is decent. All this at a price for a loaded regular brand. It’s been a good ride so far.

GLtripleB (Boxy Baby Benz)

The vehicle offers the fuel efficiency that I was looking for, though with a TriStar badge. It is fully utilitarian and spacious for my family of 4 for simply transportation and equipment. I'm digging the looks as it is a 'mini me' of our GLS 450. It has near the acoutremont of the 'BigBenz.' It does not have the heft nor occupies most of the parking space as does the BigBenz, which maskes it a pint sized zippy SportUtilityVagen.
