Exhaust temperature sensor or harness messed up by 8k miles just bought car with only 2k miles already in the shop 2 times

20250728ELECTRICAL SYSTEM

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.

20250106UNKNOWN OR OTHER

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.

20240903BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

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 “expected behavior for rear camera calibration”. 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 “pop out kind” so you constantly hear it popping out and popping back in. It’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 it’s appreciated.
