2021 MERCEDES-BENZ GLB 250 Complaints

The horn randomly starts honking while driving posing a serious safety risk. it makes driving the vehicle seem like it is stolen.

The car has 29,000 miles and I took it on a two day trip across part of the country. It was driven hard but had a oil change before leaving. After arriving home it started to sputter and have no "energy". I had the cabin filter and engine filter changed and another oil change just in case. took it to deal as it continued to sputter, even worse, jerk forward. It blew a cylinder head. Checking the internet I find that this is a usual problem with this year and model car. Why isn't it in the recall if a lot of this model has this problem?

Front right ball joint separated from lower control arm with no advance warning and the drive shaft was disconnected from the vehicle body. I was travelling at about 15 mph in a straight line through an intersection on a flat surface with no potholes. Then I saw a warning of a transmission fault in my instrument cluster, followed by a loud grinding sound. My car then came to a stop and I was unable to move the vehicle in Forward or Reverse gear. I ignition cycled the vehicle and tried forward/reverse, then someone told me that my front right wheel had separated. Upon inspecting my car from the outside, I then saw the mechanical failure that had occurred. The ball joint separated from the lower control arm . The drive shaft from the front right wheel also separated from the vehicle body. I also noticed that a ring-connector for the drive shaft had been flung maybe 4 feet from my car. My car was in a non-driveable condition and I could not engage drive with the transmission, my car had to be towed from the scene. If this had happened on a busier street or at higher speeds this would have been a severe collision. My car was just delivered to a Mercedes Dealership after sitting in a tow yard for several days, they have not yet fully inspected the vehicle. My insurance has not yet sent a representative to see the vehicle. The indication I had was a "TRANSMISSION FAULT" displayed on my instrument cluster, but I did not notice any other telltales on the instrument cluster after coming to a stop. To the best of my knowledge I did not collide with any objects before the event. There is damage to the outside of my front right rim and tire in the photos, I believe this damage occurred as part of the mechanical failure and how the tire may have deformed and the rim contacted the ground.

On September 3, 2022 while traveling east on AL highway 110 the sunroof exploded as i was driving. Notified Montgomery county sheriff Department but they refuse to do a report because it wasn’t an accident. The dealership said something had to hit the sunroof for it to Shadder. Explained to the service advisor that there were no other vehicles in the area when the incident happened, so what could have hit it. Was informed by the service advisor that the car didn’t have a recall for the sunroof on this particular model.

We purchased a brand new Mercedes GLB in January 2021, I noticed the car started to shake. On our way leaving Zion National Park, the car started shaking really hard and the engine light turned on. The car wouldn't accelerate. We had to pull over on the side of the road. We barely made it to the dealer in St. George, Utah, with the car shaking the entire time. We met with Ryan Poleszak the service adviser, and he said that he has seen this problem several times with Mercedes 4-cylinder engines in GLB, GLA, and C-class models in the past, and it looks like the car needs a new engine. After over 4 weeks and a lot of back & forth, we realized that he had no intention to fix our car. The dealer in the SouthBay told us that the dealer in St. George, Utah never registered the car into their national database with the engine problem, and there is something fishy going on. The dealer in the southbay fixed the car in less than a week. We passed all our expenses to the dealer and Emmanuel (Executive Referral Manager) who refused to do anything to help us. Till now we didn't hear anything from Emmanuel and Mercedes Bez corporate regarding our expenses. His info is below: Emmanuel Executive Referral Manager Mercedes-Benz USA, LLC (800) 367-6372 (ext. 7802) It was completely unethical of Mercedes Benz to sell us a brand new car that had engine problems in less than a year. Also, Ryan Poleszak from the dealership in St. George Utah was completely dishonest by not registering the engine problem to the Mercedes Benz national database. Car shipping from St. George Ut: $550 Rent car from Hertz: $353.31 For a total of: $903.31 which we are seeking from Mercedes-Benz USA to reimburse us since we accrued those expenses due to the engine failure of our brand new GLB.

This vehicle was purchased new, in cash, from the Mercedes-Benz dealership in Bellevue, WA. It was delivered to me, without being warned about the car being equipped with summer tires, the state of Washington has continuous rain, snow, and ice in a regular basis throughout the years, summer tires are not a good tire for an SUV such as this GLB unit in this region. On 12/27/2021 I went on an errand around my neighborhood, the road had snow and ice, and it had been serviced by our city's plows and deicer was present, during three occasions I had to stop for traffic lights, and my car skidded during all three occasions almost hitting another vehicle, and a pedestrian, my car was the only car skidding on the road, I am an excellent driver with not a single accident on my responsibility, and I have driven on snow and ice for years; this was not a novice's error. Furthermore, the car has a loud "clunk" noise coming from undercarriage, and sensations of tire slipping, possibly front and right corner, specifically when I perform a slow speed U-turn. This vehicle has not been damaged and has about 3,000.0 miles in the odometer, on 12/14/2021 I took it to the Mercedes-Benz dealership for inspection, they did not find any reason for the "clunk" noise and slipping of tires; this is when I was informed that my tires were summer tires and I needed to buy new all-weather, or winter tires, the tires "would not perform" in the winter, I was told by the M-B service representative. Here I am with a "high quality" new vehicle, with clunky scary noises, while sensing of tires slipping, and the dealership claims it to be "normal" and "safe", on top of that the car was equipped by factory with substandard tires for the region of final destination, all of which may cause accidents, damages, and/or injuries.
