2020 Mercedes-Benz GLB 250

UPDATE TO EXISTING COMPLAINT XXX Vehicle: 2020 Mercedes-Benz GLB 250 | VIN: [XXX] I am submitting an official update to my previous safety recall complaint regarding this vehicle. The safety recall was issued in late XXX, and as of XXX (over 90 days later), Mercedes-Benz still has no remedy available ("remedy not available"). Furthermore, Mercedes-Benz has repeatedly failed to meet its own estimated remedy dates provided to me in writing: 1. Initially promised for XXX by my dealership (Mercedes-Benz of Palm Beach). 2. Later pushed to XXX by Mercedes-Benz USA corporate customer care. 3. As of today, XXX, the dealership confirms the campaign is still closed and Mercedes-Benz USA refuses to provide any new target date. Please attach this update and the uploaded email correspondence to my active file, as the manufacturer is indefinitely leaving an unsafe vehicle without a fix.

SUBJECT: URGENT: Safety Recall Campaign 26V481 / XXX– Unreasonable Remedy Delay and Economic Hardship (VIN: [XXX]). I am formally logging a safety complaint regarding the unreasonable delay by Mercedes-Benz in providing a remedy for NHTSA Recall 26V481 (Mercedes Campaign XXX), affecting my vehicle (VIN: [XXX]). The manufacturer reported this critical defect to the NHTSA on XXX. Despite months having passed, and with owner notifications scheduled for XXX, the remedy remains unavailable. My local authorized dealerships (Mercedes-Benz of West Palm Beach and Delray) have canceled my service appointments, stating they have zero parts allocation from corporate and cannot perform repairs. This vehicle is a commercial asset utilized for peer-to-peer car sharing on the Turo platform. Because this recall involves a severe rollaway risk due to a defective door lock microswitch, Turo has automatically unlisted and deactivated my vehicle to comply with safety regulations. Mercedes-Benz’s failure to distribute parts is causing severe, compounding financial damages due to lost rental revenue, leaving me stranded with an unsafe vehicle that is legally and commercially inoperable. I request that the NHTSA intervene to hold the manufacturer accountable and expedite parts allocation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am submitting this complaint because I believe the repair performed under NHTSA Recall 21V990 / Mercedes-Benz Campaign 2022070009 in May 2024 failed to adequately correct the safety defect identified in the recall.When driving my axle snapped causing my tire to pop out and me to loose control of the car causing a crash into the curb. I have since been without a vehicle with Mercedes Benz of Augusta denying my vehicle after having it towed. They refused to even look at it seeing the axle issue. The recall specifically states: “Mercedes-Benz AG has determined that on certain Model Year 2019–2021 A-Class and GLB-Class vehicles, the corrosion protection of the integral carrier of the front axle might not be sustained over the lifetime of the vehicle. Under specific environmental influences, corrosion of the integral carrier of the front axle might occur after several years. As a result, depending on the intensity and location of the corrosion, an impairment of the structural durability of the integral carrier as well as the connection to other components cannot be ruled out. In this case, vehicle steering might be affected which could potentially increase the risk of a crash.” My 2020 Mercedes-Benz GLB 250 received the recall repair in May 2024. Despite the recall repair being completed, the vehicle subsequently experienced a serious front-end/steering-related mechanical failure involving components connected to the front axle, resulting in an accident and loss of steering control.I am particularly concerned because the failure occurred in the same general front-axle area addressed by Recall 21V990, and the recall itself specifically identifies the possibility that deterioration of the integral carrier and its connections can affect steering and increase the risk of a crash.I am requesting that NHTSA investigate whether the May 2024 recall remedy was properly performed and whether the recall remedy adequately addresses the underlying safety defect in this vehicle.

I am submitting this formal complaint regarding a serious safety incident involving my 2020 Mercedes-Benz GLB, which directly reflects the defect outlined in Recall 20V-480 (Rear Spoiler Detachment). Although my VIN is not officially included in the affected range, the exact failure described in the recall occurred on my vehicle. On or about June 16, 2025, at approximately 3:00 p.m., I was driving and I noticed an object in my rearview mirror that had become airborne and was causing vehicles behind me to swerve to avoid it. Moments later, two separate vehicles pulled up alongside me, and the drivers began waving their arms to get my attention. I exited the roadway and pulled into the Walmart parking lot, where a couple in a pickup truck approached me and informed me that the rear spoiler of my vehicle had flown off. I got out to inspect the vehicle, and indeed, the spoiler was completely gone. I returned to the area where I first saw the airborne object, attempting to locate the detached part, but was unsuccessful in recovering it. I contacted Mercedes-Benz USA and my local dealership on June 17, 2025, and was told that because my vehicle’s VIN is not listed under the recall, I would be responsible for the full cost of inspection and repair. Frankly, that position is unacceptable for the following reasons: - Recall 20V-480 describes a defect involving improperly welded rear spoilers on 2020 GLB250 models, which can detach while driving. That is exactly what happened to my vehicle under normal conditions. - The spoiler detached while the vehicle was in motion, creating a dangerous road hazard—just as outlined in the recall. - The vehicle has never been involved in a collision or sustained rear-end damage. It has not been subjected to outside interference. - My VIN has been included in at least five previous recalls, underscoring that my vehicle was part of broader quality issues during that production period.

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 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.

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
