2025 Mercedes-Benz GLB 250

On June 5 2026, my wife drove the vehicle into the garage. While she was exiting the vehicle with the driver's door open, the vehicle unexpectedly continued moving backward. My wife had to move out of the vehicle's path to avoid being struck or potentially crushed. The vehicle continued moving with the driver's door open, and the open door ultimately became lodged against a structural portion of the garage-door opening. Fortunately, my wife escaped physical injury. The vehicle and driver's-door area, however, sustained substantial damage.

Incident

Complaint Slight creaking noises when steering. Cause Noises may come from one or more sleeves of the horn contact plate. Remedy Remove the horn contact plate and check the sleeves for noise; see attached video. If necessary, apply lubricant to the sleeves.

Complaint Repeat workshop visit for vehicle vibration while braking from 60MPH. NOTE: Although the symptom is similar to a tire or wheel vibration, it is usually readily noticeable that it is distinctly different if it happens at all times or only while braking. Cause Although the cause of the vibration is most likely due to excessive lateral runout on the rotor or hub/wheel bearing, the system as a whole needs to be checked for other possible contributors. 1. Prior collision damage. 2. Excessive vehicle sitting times without rotating components. 3. Wheel bearing/hub lateral runout. 4. Wheel mating interface has been overtightened (did not follow WIS torque procedures). 5. Mating interfaces have been excessively modified (painted, gouged, bent, etc...). Remedy Read through the entire attached worksheet prior to performing. After performing, please review the final page and perform work accordingly. NOTE: This document is not pre‑authorization or otherwise dealing with warranty. This is intended for diagnostic purposes only. If there are any questions on how to proceed OR The work sheet has been performed and the vehicle has returned with the same concern. Please perform the measurements as seen in the worksheet again and open a TIPS case to the Body, Chassis, and Entertainment team.

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. Please update the Head unit software to E505.9

Complaint Clanking noise from the area of the speakers in the doors. Cause Under analysis. Remedy To narrow down the cause, first of all remove the door trim. • If the noise continues to occur even with the door trim removed, then continue the diagnosis working towards the speaker and if necessary, create a TIPS case with an informative video as an attachment. Note: Please refer to this document in the warranty claim and, once diagnosis is completed, select the damage code depending on the component part that is causing the issue. • If the noise stops when the door trim is removed, please proceed in accordance with LI72.10‑P‑067691. Information: In this case, do not use a damage code for the speakers in the warranty claim!

Complaint Intermittent shift feel or thud/clunk noise perceived, such as a brief jerk or transmission reaction during certain driving situations. May be most noticeable when transitioning from a coasting condition to accelerator pedal application. May occur in all drive modes. Cause Dual‑clutch transmissions (DCT) inherently exhibit more dynamic shifting behavior compared to other types of transmissions. This is due to the use of physical clutches for starting and gear changes. In certain situations, dynamic driving behavior can lead to a slight jerk sensation which is a normal technical characteristic of the transmission. A typical example is a "Change of Mind" situation: • The customer is coasting towards a red traffic light. • The traffic light turns green while the vehicle is still coasting. • The customer then presses the accelerator pedal. In these situations, a slight jerk may occur briefly because the transmission must quickly engage the appropriate gear and control the clutches accordingly. Since shift forks are responsible for engaging the gears during shifting, a slight shifting noise may also be noticeable. Please note driving programs S, S+, and M are designed to provide sportier vehicle behavior and are not optimized primarily for maximum comfort, so this operation may be more audible. Remedy Verify the customer's concern and confirm proper transmission operation. If no faults or abnormal operating conditions are identified by IPR (Intelligent Predictive Repair), no hardware replacement is necessary. Inform the customer that the transmission has been designed to provide direct gear engagement and responsive vehicle performance. Under certain operating conditions, brief shift sensations may be perceptible and are consistent with the operating characteristics of the dual‑clutch transmission

Complaint Temporary no start condition with check engine light and multiple warning messages. When performing a quick test, the following fault code is stored in Y3/14 ‑ Transmission control for 8‑speed dual‑clutch transmission (DKG): P24F100 The wake‑up line of the control unit has a short circuit to positive. Cause Possible signal timing between EZS control unit and Transmission Control Unit (DKG) Remedy As of 7/15/2026, new SCN coding is available for the EZS control unit. IPR will advise to open a TIPS case for EZS (N73), this is due to GLA models requiring support for SCN coding procedure. GLB (X247) and CLA (118) No TIPS case necessary. 1. SCN coding of EZS Control Unit 2. Clear all faults and perform extended road test with multiple drive cycles GLA (H247) Special function password required. 1. Verify if special procedure Central Locking ‑ Development Data is present in EZS (figure 1) 2. Submit a TIPS case to the Powertrain Inbox with the following information: ‑ Initial Quick Test w/ freeze frame data ‑ IPR Result ‑ DKG Control Unit Log ‑ EZS Control Unit Log ‑ Initial EEPROM data ‑ EZS special procedure menu If the vehicle has had this LI performed and P24F100 has returned, please submit a TIPS case to the Powertrain Inbox.
