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.

I have a defective vehicle built during COVID…Rain water accumulates next to the driver’s side seat. After 6 attempts for the dealership to identify the issue they determined that replacing the door and frame seals would work. Two weeks later the vehicle was ready…Went to pick it up and they did a horrible job on installing the new seals and they cut the headliner too where it didn’t even meet the seal. Needless to say I left the vehicle to redo the repair, in the interim I filed a claim with MB Customer Care… Two and a half weeks later the vehicle was ready… I Inspected the vehicle with the service manager and found a 10 inch circular wet spot on the headliner in the rear of the vehicle. At this point the service manager said that he was going to work with MB Corporate and assigned me to a sales consultant to get me out of the vehicle and into another at my current lease price….Here it is a almost 2 months later my vehicle still has the original leak and the headliner above the driver gets wet and is stained and the electronic display flashes on and off and the AC fan sounds like a jet engine. I cannot get help from Mercedes-Benz corporate or any response from the dealership. This one is a lemon!

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.
