Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

How this campaign compares
At 2,943 vehicles this is a bigger campaign than 70% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2023 to 2025, so the oldest vehicles on it were 2 model years old when the defect was reported to NHTSA.
Mercedes-Benz vehicles have been recalled over the electrical system 71 times before this, most recently in February 2025 as 25V050000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry 3 other recalls published here: 25V533000 (steering), 25V379000 (structure), 24V115000 (electrical system).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by Mercedes-Benz USA, LLC with NHTSA on February 28, 2025 as campaign 25V129000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
