2026 Mercedes-Benz CLA 250+ (ev)

While driving at 50mph, the vehicle came to a full stop in 2 seconds by auto breaking (to avoid collision) when there was no object or vehicle in front of the car. I almost got rear-ended as stopping from 50mph to 0 mph on a highway was extremely dangerous but luckily the car behind me was able to use the lane to my right to avoid the collision. When the vehicle was taken to the service center, the computer systems showed no record of this incident. However, I do have a dashcam footage of it. In the video, you can clearly see a stopped car on the left turn lane (the break lights of the car is visible and the car is stationary when the video is analyzed frame by frame.) The driving lane is curving to the right and the vehicle is also turning to the right following the lane. (this is verified by following the double yellow line - then the single solid white line and vehicle's motion to the right.) Despite all this, the car slammed the breaks and stopped. The video is seen by the service center workers as well. They updated the software on the car at the time of service. An escalated ticket was also created with Mercedes corporate office with case number: 23763407. At the very least, the cars should be keeping records of collision avoiding breaking administered by the car's system so when you're at the service center, there's a record of what happened. This incident could have resulted into a high-speed collision with severe injuries to the people in both vehicles and one pet. And if it did, the car would have shown zero record of functions performed and the drivers would have been blamed.

Incident

Complaint The vehicle pulls to the left or right. Cause In vehicles with Car Package Release "CPR" 2.1.0 or prior, the calibration value for the straight‑line stability of the electric power steering is not fully calibrated. Remedy Install Car Package Release 2.1.1 or later. Straight‑line normalization is then relearned during normal driving followed by a bus sleep. After the update, fault code P063544 may be active and stored in the electric power steering control unit, as the learned end stops are deleted during the update. This does not result in any functional limitations or warning messages; the end stops are learned during normal vehicle use. The fault code is cleared by automatic means after the teach‑in of the end stops is complete.

Complaint 174 with MB.OS 2.1.3 ‑ Driver Assistance System Limited in Instrument Cluster and Does Not Self‑Extinguish. When vehicle is shut off, instrument cluster message appears for "Driver Assistance Systems Available". Cause Under Determination. Remedy Perform initial startup of the head unit (A26/17) and the intelligent drive controller (N62/5).

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 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 Display message in the instrument cluster for "Active Brake Assist Inoperative" or "DISTRONIC inoperative". AND Fault code C1100FC or C1100FD is Active or Active and Stored in MRR_F_Gen6 (B29/20). Cause The holder for the MRR_F_Gen6 (B29/20) front radar sensor may no longer have the correct alignment (angular position). Remedy Confirm whether the instrument cluster message was already present upon receipt of the vehicle by the end customer. Check if DTC mileage was present prior to vehicle PDI/Sale of vehicle. In this case, submit under warranty with the specified SSL. If vehicle exhibited the instrument cluster message AND DTC mileage was AFTER customer hand‑over, cost settlement under warranty is not possible as it is due to outside damages. Note: Additionally, it is possible to obtain a timestamp for a possible collision, including the date, if the end customer has purchased the "Parking and Collision Alert" digital service. In both cases, the front radar holder must be replaced. After replacing the radar holder, perform calibration in IDC_Gen6 (N62/5).

Complaint 174 with MB.OS 2.1.1 ‑ Driver Assistance System Limited in Instrument Cluster and Does Not Self‑Extinguish. When vehicle is shut off, instrument cluster message appears for "Driver Assistance Systems Available". Cause Under Determination. Remedy Perform initial startup of the head unit (A26/17) and the intelligent drive controller (N62/5).
