Should You Buy the 2022 Mercedes-Benz GLB?
Of the five scored GLB years, 2022 holds up best, and it rates above average against other 2022 SUVs. Federal recall records list no recalls for it. The 2021 model rates worse, with 30 complaints and 10 recalls. The 2023 model rates about the same as 2022 and also has no recalls.
Owner complaints center on driver assistance, speed control, and suspension. Adaptive cruise control sometimes fails to slow or brake, and one owner saw it jump from 35 to 50 mph. Those reports came from nearly new cars. One speed control complaint describes unintended acceleration at about 5,000 miles, ending in a brick wall with air bags deployed. Another describes the transmission slipping into neutral at 65 mph, which the dealer blamed on a needed software update. Suspension complaints involve a warning light that limits speed to 50 mph and a creak the dealer could not reproduce.
On a test drive, check that cruise control and automatic braking respond consistently. Ask for service records showing software updates and any suspension warning visits.
Compared to the 2023 Mercedes-Benz GLB, which scored 1 points lower. See also the 2021 Mercedes-Benz GLB for an earlier comparison.

Used Buying Checklist
Key things to inspect or verify before purchasing a 2022 Mercedes-Benz GLB.
Test adaptive cruise behind highway traffic and confirm it slows and brakes every time.
Drive past posted speed-limit signs with cruise on and watch for the car speeding up on its own.
Ask a Mercedes dealer whether all transmission software updates have been applied to this car.
Drive at highway speed and watch for a "transmission malfunction stop" message or lost acceleration.
Make tight turns in a parking lot and listen for creaking from the wheel area.
Check the instrument cluster for a suspension warning or a 50 mph speed limit message.
Lower the driver window fully and confirm the radio works.
2022 Mercedes-Benz GLB Common Problems by Component
13 owner complaints grouped by vehicle system.
FORWARD COLLISION AVOIDANCE
3 complaintsDriver assistance features work inconsistently. Reports describe adaptive cruise control that sometimes fails to slow down or brake, and random speed increases past the limit the car reads from road signs, such as climbing from 35 to 50 mph. Lane control and automatic braking may or may not engage, and slowing for a turn lane is also unpredictable. These problems show up on nearly new cars, within the first 1136 miles. The main risk is the car failing to slow or brake when the driver expects it to.
VEHICLE SPEED CONTROL
2 complaintsSafety-relatedThe car either surges forward or suddenly loses drive. One crash report describes unintended acceleration at about 5,000 miles while pulling into a driveway in bad weather. The car pulled right, crossed a lawn, and hit a brick wall. The air bags deployed, and the driver reported neck, back, and chest pain. A separate report describes the transmission slipping into neutral at 65 mph with a "transmission malfunction stop" message, which left steering and brakes but no acceleration. The dealer blamed a needed software update, not a hardware fault.
SUSPENSION
2 complaintsA suspension warning light comes on intermittently and tells the driver not to go over 50 mph. A loud creaking from the wheel area is also reported while driving, turning corners, and pulling in and out of driveways, and the dealer could not reproduce it. Rear shock problems are reported alongside other faults, including electrical trouble, a fan motor issue, a driver window that will not fully lower, and a radio that needed repair. These complaints are mostly warnings and noises that are hard to diagnose.

UNKNOWN OR OTHER
1 complaintParked the car not far from home, when my boyfriend got out and shut the door, the sunroof completely imploded. Tempered yet sharp shards were everywhere including my mouth, hair and body. MB took no responsibility and wound even have the car towed. Roof was repaired via my car insurance including private towing. MB wanted nothing to do with me. I do know that this has been a serious problem all over the country for some time. Please advise.

SERVICE BRAKES (1 complaints)
SERVICE BRAKES
1 complaintBrake over heats because of rust caused by rain which builds up causing brakes to freeze up. Explanation from dealer. In fact told us we need to dry brakes off if we drive in rain and park in garage for more than 2 days or we will have it happen again. Brakes freeze and car locked up and can’t move it. We bought the car used had it inspected by a MBD in Atlanta G. Bulkhead , told breaks were like new. Mileage 23,666 miles. Put on about 4000 miles now brakes gone froze up from rain. Garage kept. While driving car we were noticing almost like the breakers were on but not stepping on break. A pulling like action. Seemed like emergency brake was on. Car at dealership now in Greenville SC Mercedes Benz dealer.
ELECTRICAL SYSTEM (1 complaints)
ELECTRICAL SYSTEM
1 complaintSafety-relatedthis car really has a lot of issues and honestly if I didn’t know what to do last night and didn’t know about cars, it could have seriously cost me my life but luckily I was able to move out the way of a truck that was coming fast behind me while I was at a traffic light and when the light turned green the car would not start back up from the automatic stop when you make stops and because the auto shut off never came back on and I had to literally make a split second decision and put it in park and start up again and go quick. The check engine light has been on since July 14,2024 and I bought the car on July 13,2024 and the dealership has not done anything about this issues and this morning these are all the codes that came up and there’s a lot of codes and Mercedes hasn’t called me back even after the calls and emails I’ve sent them, no one is calling me back.
WHEELS (1 complaints)
WHEELS
1 complaintI purchased my car in April of this year 2022 and have driven less than 10K miles. The tread of my front two tires has already worn down to less than 3/32 compared to the rear wheel 6/32. Driving conditions are normal and according to Mercedes this is known issue. This exceeds normal wear and tear and should be a safety concern.
VISIBILITY (1 complaints)
VISIBILITY
1 complaintThe contact owns a 2022 Mercedes-Benz GLB250. The contact stated that upon purchase of the vehicle, he noticed a glare coming from the ridges of the hood which became distracting while driving. The contact stated that as the sun began going down, the glare worsened, forcing the contact place his hand over his eyes to deflect the glare. The manufacturer was notified of the issue and informed the contact that they had never heard of the issue before. The dealer was not notified of the issue. The vehicle was not repaired. The failure mileage was approximately 150.
