MERCEDES-BENZ GLB 250 2024 ENGINE

Rear Camera malfunction The flap of the reversing camera opens and closes by itself during forward travel, making a loud thumb noise every time the car slows down to an intersection. No camera image is displayed in the head unit.  This is a driving distraction for the operator and thus a safety issue as the sound is loud and its made constantly at every stop when you slow down.   Dealer was able to reproduce and said this was normal behavior. Recommended disabling the Parktronic driving assistance feature to not engage sensors, but this in itself would be inactivating an important safety feature.   This problem is widely reported online.

MERCEDES-BENZ GLB 250 2024 ELECTRICAL SYSTEM

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

MERCEDES-BENZ GLB 250 2024 FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Every time I start my new Mercedes, the backup camera MUST recalibrate itself even if I never put the vehicle in reverse and am driving forward.  This happens throughout the entire drive, every single time.  The Mercedes forums all corroborate this as other models; not just the GLB, experience this.  Mercedes denies anything is wrong and says this is âexpected behavior for rear camera calibrationâ.  This makes absolutely no sense why a rear camera would need to recalibrate itself on every drive even when you never place the car in reverse.  Furthermore, the backup camera is the âpop out kindâ so you constantly hear it popping out and popping back in.  Itâs extremely distracting as it continues to pop in and out as I slow in traffic at a signal or stop sign.  This is with certainty, a manufacturing defect and must be remediated.  Thanks for listening as itâs appreciated.
