2019 Mercedes-Benz A 220

I am filing a vehicle safety complaint regarding my 2019 Mercedes-Benz A220 equipped with the M260 engine. While driving on a public street, my vehicle experienced an unexpected loss of engine power and stalling. The engine also exhibited significant shaking, misfiring, and activation of the check-engine warning light. The unexpected loss of power while driving created a dangerous situation because I could have been involved in a collision with another vehicle. I was extremely concerned for my safety and the safety of other motorists. My mechanic subsequently diagnosed the vehicle with a cylinder head failure and advised me that continuing to drive could be dangerous. Because of the seriousness of the mechanical problem and the safety risks involved, I had the vehicle repaired. The repair cost approximately $3,800 and was performed by an independent mechanic using genuine Mercedes-Benz parts purchased from an authorized Mercedes-Benz dealership. I later learned that Mercedes-Benz had reportedly extended warranty coverage for certain M260 engine cylinder head failures to 15 years or 150,000 miles. I am concerned that other Mercedes-Benz vehicles equipped with the same engine could experience similar failures, potentially resulting in unexpected engine stalling or loss of power while driving. I respectfully request that NHTSA investigate whether this cylinder head failure represents a broader vehicle safety defect that could endanger drivers, passengers, and other motorists.

I was driving home from work down the hwy, when the sun visor shade fell down and hit me in the head and covered my face, temporarily blinding me, like a blanket was pulled over my face. It's very difficult to see the road or other drivers when you are blinded at 70mph! Car only had 15,500 miles on it...

Vehicle: 2019 Mercedes-Benz A220 VIN: [XXX] Dealer: Mercedes-Benz of Walnut Creek (Walnut Creek, CA) I am reporting multiple safety defects involving federally regulated systems. The vehicle has repeatedly activated emergency braking at freeway speeds without reason, posing a significant risk of collision. The brake assist warning appears frequently, and both the front and rear proximity/collision sensors display a full red warning state with continuous audible alerts. These alerts cannot be cleared without manually disabling the safety system each time the vehicle is started. One of the sensors physically detached from the vehicle. Backup and parking assist features do not function correctly, and the vehicle repeatedly shows malfunction warnings. The dealer verbally stated that a “manufacturer-covered engine repair” was needed, but would not disclose the nature of the repair or whether it relates to these safety issues. After two weeks in their possession, the dealer refused to provide written documentation of any diagnostics or repairs performed. They attempted to return the vehicle without confirming whether it is safe to operate and threatened storage fees when I requested written confirmation. These issues involve systems covered under FMVSS 101, 111, 126, and 135, including electronic stability control, braking, rear visibility, and driver-interface warnings. The failures pose a clear safety risk to the driver and other motorists. I am requesting NHTSA review these defects for potential investigation or recall.

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 Noises in the steering column area when steering. See example file in the attachments area: "MRSM‑Schleifgeräusch_SCCMGrindingNoises. MOV". Cause Under analysis. Remedy Check which area of the steering column the noises occur in. Do the noises tend to occur at the bottom in the driver footwell or do they tend to occur in the area of the steering column switch module (MRSM/SCCM)? If the noises occur in the area of the MRSM/SCCM, work through the following points: ‑ Loosen screws of the MRSM/SCCM and steering wheel, re‑align the MRSM/SCCM, and re‑fasten the screws (see WIS). Sometimes there is stress at the MRSM/SCCM and noises occur. ‑ If noises continue to occur, swap the MRSM/SCCM into a vehicle without any (noise) complaints. ‑ If the noises occur with the MRSM/SCCM complained about when it is in the vehicle without a complaint (donor vehicle), the MRSM/SCCM can be replaced. ‑ If noises also occur in the customer vehicle with the MRSM/SCCM from the reference vehicle, the MRSM/SCCM is not the cause and must not be replaced. Notes: ‑ When installing the MRSM/SCCM, make sure that no damage occurs! ‑ If the noise is due to the steering wheel (see attachment "Lenkrad‑Schleifgeräusch_SteeringWheel‑GrindingNoises.mp4"), please use LI46.10‑P‑077313. ‑ Only disassemble and mount all component parts in the "straight‑ahead position" (see also WIS). ‑ Please refer to this LI in the "Notes" section of the warranty claim!

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
