Should You Buy the 2024 Mercedes-Benz GLB?

Reliability is good, though nothing sets this year apart from its neighbors. It sits in the middle of the five scored GLB years and runs close to average among 2024 SUVs. Owners filed 4 complaints. The 2023 model rates about the same.

The one pattern is the pop-out rear camera flap. It opens and closes on its own while the car drives forward, with a loud thump each time it slows for a stop. Owners also report the camera recalibrating throughout a drive and sometimes no image on the screen. Dealers and Mercedes have called this normal. One suggested workaround, turning off Parktronic parking assist, disables a safety feature. Federal recall records show one recall, for the hydraulic service brakes.

Ask for proof that the brake recall work was done. On a test drive, brake to a stop a few times and watch the flap and the screen. The 2023 is a fair alternative, with no recalls on record.

ELECTRICAL SYSTEM

2 complaints

The pop-out rear camera flap opens and closes on its own while the car drives forward, making a loud thump that tends to repeat each time the car slows for a stop. Reports also describe the camera recalibrating throughout every drive without reverse being selected, and in some cases no camera image appears on the screen. Owners call the noise a distraction while driving. Dealers and Mercedes have called it normal behavior. One suggested workaround is turning off Parktronic parking assist, which disables a safety feature. The 2 complaints show no mileage pattern.

1. Transmission Problem Vehicle Rolls backwards when the gear / transmission is in "Drive". It happens in these two situations: a) I am stopped at a Traffic Light which is Red. The road is at a moderate upward incline. When the Light turns Green, and I move my foot from the Break pedal to the Accelerator to move forward, the GLB rolls backwards even though the transmission is, and has been, in "Drive". b) I am backing out of my garage. Our driveway is at a moderate Backward / Downward Decline. As I reach the point where I shift the gear into "Drive", the car still continues to roll backwards. This is despite the fact that I had to depress the Brake pedal to place the vehicle in Drive. c) I have checked the settings and confirmed that the transmission is NOT in manual mode. The problem is happening when the Transmission is in automatic mode. I have been cautious and prevented an accident over the last 6 months that I have owned this car. ___________________________________ 2. Cruise Control: This is a situation is that I am driving, and I have the Cruise Control "On". I encounter the traffic to be slowing, so I push the "Cancel" button for the Cruise Control in the left bar of the steering wheel. As I manipulate the wheel to make a left turn, the "Resume" button, also in the left bar of the steering wheel, gets touched without my realization. The GLB zooms ahead violently! This is dangerous and unexpected acceleration. A corollary to this malady is that the radio suddenly blasts loud as I manipulate the steering wheel to make a right turn. The radio volume button in the bar of the steering wheel gets touched without my realization. This is dangerous. It can make the Driver jump and react suddenly to the unexpected loud noise. I REPORTED THESE 2 PROBLEMS TO MERCEDES BENZ OF NORTH AMERICA THROUGH THE WEBSITE IN DETAIL AS ABOVE ON DEC 9, 2024 THE SITE PROMISES A RESPONSE IN 24 HOURS. I HAVE NO RESPONSE

Frequently Asked Questions

Is the 2024 Mercedes-Benz GLB reliable?

Yes, it earns a good reliability standing. It is close to average against other 2024 SUVs and lands in the middle of the five scored GLB years. Owners filed only 4 complaints, and the one clear pattern involves the rear camera rather than the drivetrain. It also has one federal recall.

What are the most common problems with the 2024 Mercedes-Benz GLB?

The most common problem is the pop-out rear camera. Owners say the flap opens and closes on its own while driving forward, with a loud thump when slowing for stops. The camera may also recalibrate during the drive, and sometimes no image appears on the screen.

Does the 2024 Mercedes-Benz GLB have rear camera problems?

Yes, two complaints describe them. The flap moves by itself at low speeds, the camera recalibrates without reverse selected, and some owners get no picture. Dealers and Mercedes have called it normal behavior. The reports show no mileage pattern, so a test drive is the best check.

Has the 2024 Mercedes-Benz GLB been recalled?

Yes, federal recall records list one recall for this model year. It covers the service brakes, hydraulic. The data does not give more detail than that area. Ask the seller or a Mercedes-Benz dealer to confirm the recall work was completed on the specific car.

Is the 2024 Mercedes-Benz GLB better than the 2023?

Not clearly. Both years rate good and about the same. The 2023 has 12 complaints and no recalls, while the 2024 has 4 complaints and one brake recall. The 2024 has had less time on the road to collect complaints, so neither year is a clear pick.

Don’t buy a 2024 Mercedes-Benz GLB without checking its VIN first — hidden accidents, title issues, and open recalls could cost you thousands.
