Mercedes Software Update Left My CLA 200 Hybrid Stranded

On June 10, 2026, while driving my 2023 Mercedes-Benz CLA 200 Hybrid with approximately 50,000 km, the vehicle first displayed a "Malfunction" warning and, about two minutes later, a "Refer to the Owner's Manual" message. After safely pulling over and parking the vehicle, it would no longer start. Because I could not move the car from the parking area, I had to arrange and pay for a tow truck.

At first, I believed the issue might be related to the battery, so I had the vehicle taken to the authorized Mercedes-Benz service center in Ankara. After inspecting the vehicle, the service department informed me that the problem was caused by an error in a software update installed by Mercedes-Benz. According to the service center, the vehicle had entered a self-protection mode because of the software issue, and the solution was to reinstall and update the software.

What I cannot accept is being charged for a problem that the authorized service itself identified as being caused by Mercedes-Benz software. Although my vehicle's warranty remains valid until November 2026, I was told that my warranty had been voided because one scheduled maintenance service was performed approximately 1,000 km late and another approximately 2,000 km late. All maintenance on the vehicle has been performed at authorized Mercedes-Benz service centers, yet I was still required to pay for repairs related to a software issue attributed to Mercedes-Benz.

As a result of this incident, I was forced to pay approximately $64 for towing services and $362 for the authorized service repair, for a total of approximately $426. My service invoice/work order number is L102026000000657.

I request that Mercedes-Benz review this matter, reimburse the costs I incurred as a result of the software-related failure, and provide me with a clear written explanation regarding the decision to deny my warranty coverage. I also ask for a prompt resolution to this matter.
