2024 Mercedes-Benz AMG GLB35

Vehicle stalls out at highway speeds. It will be in gear, shown on the dash, it will be redlining, but not move. It will stall out while the vehicle is in motion. The accelerator does not provide power to the transmission and acts as if it is in neutral. All I can do is coast to the side of the road and power off the car, open the door to provide a full power down, then restart the vehicle. This has happened over a dozen times since August 2025. Mercedes says there is no fix. It’s been in the shop more than 10 times for over 60 days. They have even sent out field engineers who cannot duplicate the issue, yet there are codes stored in the cars computer. The car also does not always shift into reverse or drive from park. The transmission often has a small 1-2 second delay upon pressing the accelerator from a stop, which sometimes puts me into the path of an oncoming car, say when turning left on a flashing yellow. Since the car has a delayed response, it puts me I harms way when I may have had time to go, but then it didn’t move. It also drives very jerky at times, shifts late or not at all. I have video of this but cannot load it through this form, so we need to send it a different way. I’ve opened multiple buy back requests as a lemon but Mercedes says no. I have far more documents than I can upload here if you have a way to send them. Mercedes says the car is safe and told me in person “if you crash, that’s why you have airbags”. Because the car can stall without notice at highway speeds, it is not safe in my opinion and it’s appalling they won’t fix it or buy it back.

Incident

Jul 14, 2026

Complaint CEL light on with no drivability concerns. Cause Signal timing error. Remedy 167, 465: SW has been released. Update the FSAM to the latest SW version. 290, 118, 243, 247: Software is still in development. This fault code does not cause a drivability concern and will clear itself within 2-3 key cycles. The vehicle can be released back to the customer.

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4. Reinstall side shafts Note: Before using the antifriction coating (Molykote), stir it or shake it thoroughly for (at least 1 minute).

Complaint Radio station cover art does not refresh when switching stations. The UI continues to show the old station’s artwork instead of updating to the new one. Cause When a new station change request is triggered, a temporary glitch is causing the Head Unit application to fail to overwrite the previous request. This glitch is causing the cover art mismatch in the Radio application. Remedy Please do not replace any parts. The E505.9 software is released and available in XENTRY Q3 2026.

Dear Mercedes-Benz USA Dealers, The part numbers listed in the chart below should no longer be installed, and any existing stock must be returned to your facing PDC. The deadline for all dealer returns is no later than Thursday, July 9, 2026. After July 9th, returns of these parts will no longer be accepted. These parts should be returned via ZSR Special Return, using item category SCM Authorized Part Return. Please include a copy of this NCU as your authorization to return these parts. This procedure will not affect your return allowance. All returned parts will be replaced in accordance with the chart provided below.

Complaint Frequent rear view camera flap actuations and/or noise associated. NOTE: Rear view camera functions are NOT affected and still perform in accordance with regulatory requirements. Cause Calibration of the reversing camera is in progress. This is not a malfunction, but an intended system behavior. Remedy An optimization has been implemented to reduce the quantity of rearview camera flap actuations for calibration. Open a TIPS case stating "Please add the option code per LI54.71-P-080349 for the Rearview Camera Noise Optimization". Once the option code has been added, perform the below based on which option codes the vehicle has. FOR VEHICLES WITH 235 ONLY: 1) Update and SCN code N62/* (PARK Control Unit) 2) Perform verification that optimization is as-expected as seen below. FOR VEHICLES WITH 235 + 501: 1) Update and SCN code A26/17 (Head Unit) 2) Update and SCN code N62/* (PARK Control Unit) 3) Perform verification that optimization is as-expected as seen below. IMPORTANT NOTE for vehicles with 235 + 501 ONLY: *For vehicles with 235 only, the "Movable 3D View" is not available due to not having 360 camera feature. Therefore the view was never present.* After both control units have been SCN coded, the "Movable 3D View" feature in the head unit will no longer be available. With this change there will be two distinct differences: 1) The "3D" icon when in the top down vehicle view, will no longer be present on the head unit. 2) The digital rendering of the vehicle with the ability to spatially move around the vehicle is no longer possible. This view is replaced with 2D static images of the left and right sides. Prior to releasing the vehicle, please verify the following: • Rear camera flap when calibrating after a key cycle bus sleep will stay open to 29 MPH and then close. Will reopen, when calibrating, at 9 MPH. • The head unit screens mentioned above appear the same as "View AFTER SCN Coding" as shown in the attachment.
