2020 MERCEDES-BENZ GLB 250 Complaints

Car constantly cuts out and loses power as well as occasionally shuts off for no reason. Causing very hazardous driving conditions. I have noticed that this is a common issue stated in online forums with this particular car as well. It is more times than not an issue with the engine head and valves.

The contact owns a 2020 Mercedes-Benz GLB250. The contact stated while driving 45 MPH, the rear spoiler detached from the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was determined that the spoiler needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 47,000.

Power Liftgate (via key fob – SmartKey). Mercedes GLB250. Was told by Mercedes employees that all cars operate the same. oSensor that automatically stops liftgate if it detects an obstruction does not retract to allow someone reaching in the trunk to safely exit the trunk. oThe liftgate stops, but it does not do so until it has hit/touched the objection or obstruction. oWhen you press the trunk button on the key fob, the liftgate only raises slightly (maybe 2 inches). oIf you press the key fob again, the liftgate just continues to go up and down within those few inches and continues to hit/touch the object/obstruction each time you press the button. Half of my body was trapped in the trunk. Suffered injury to shoulder and hand. oI was taking grocery bags out of the trunk and had the key fob in my pocket. oAn item fell out of the bag so I reached into the trunk to grab it. oAs I leaned in, the body of the car must have come into contact with the key fob and the trunk came down (closed). oI did not have time to exit the trunk and ½ of my body became trapped in the trunk. oI had just enough space to move my right hand to take the key out of my pocket. oI pressed the trunk button, but the liftgate did not fully retract. It went up slightly and came back down hitting/touching my body. oI did not have enough room to get out of the trunk. oI was in a garage where no one could hear me scream for help. oI had to push up with my left hand and use excessive force with my back and right shoulder to lift the heavy trunk. Mercedes inspected the car and said nothing is wrong. Letter provided. oSeveral Mercedes employees at the dealership were present when I demonstrated the issue. They had no explanation. oSales manager stated that he tested the trunk (cars located at the dealership) and they do retract but understood my concerns as it only retracts slightly. oNo one seems to understand that serious risk this possesses, unless they were to be trapped i

The contact owns a 2020 Mercedes-Benz GLB250. The contact stated while opening the liftgate, the rear spoiler above the liftgate became loosened while raising and scratched the roof of the vehicle. The contact stated that the rear spoiler had not detached. The vehicle was taken to the dealer, and the contact was informed that the failure was caused by external factors, unrelated to NHTSA Campaign Number: 20V480000 (Structure), which had previously been performed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 40,000.

The engine made a knocking sound and i pulled over on the side of the road took the car to MB dealership to get the recall fixed but i was told the recall cannot be fixed until the engine is fixed. MBUSA refuses to replace the engine even though it is fully covered under warranty. Thus because i cannot get a recall done for my safety unless i get an engine replaced. This is absolutely horrible. MB knows they produced a bad engine and are forcing us to pay out of our pocket then they will fix the recall on the car.

Engine failure. Engine has no compression which is causing injection fueler to fail. The head engine has gone bad at 50,000 miles. Head engine must be replaced and is on back order per Mercerdes Benz. After research on the issue I’ve noticed the Year/Make/Model this is issue is common at the 40k-50k mile mark. This is a manufactured issue that Mercerdes needs to fix if so common within the car and also unsafe. Not okay for a new car to have engine failure this early

The contact owns a 2020 Mercedes-Benz GLB250. The contact stated that there was an abnormal fuel odor inside the cabin of the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer on three occasions however, the dealer was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 45,000.

Since the beginning of the vehicle purchase, we heard fine metal rattling sound on the front driver side tire. Had it checked with the dealer and they recommended no repair. Now driven about 35K miles and started very loud metal scratching sound when wheels turned to right. Inspection showed bent brake cover that was wearing tire uneven. Dealer claims that we went over a large bump that bent the brake cover but no such thing happened and this location is where we have been hearing this fine rattling since buying new. Raising a possibility that the manufacturing and securing process of parts around this area was not done fully and eventually cause inappropriate contact induced brake covering damage and tire wear.

My GLB250 does not fall under recall 2020070009 however after taking it through the car wash the entire display instrument went out and car will not turn on and off. They are telling me the car had water damage and it is on me to fix?
