- The defect
- Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023 EQE 350, S580e, 2022-2023 EQS 450, EQS 580, 2022 AMG EQS 53, and EQS 450+ vehicles. The high-voltage battery monitoring system software may not alert the driver of a battery malfunction. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 305, "Electric-powered vehicles: Electrolyte Spillage and Electrical Shock Protection."
- What it can cause
- A high-voltage battery monitoring system that does not alert the driver of a battery malfunction may increase the risk of an injury.
- What the dealer does
- Dealers will update the battery management system software, free of charge. Owner notification letters were mailed beginning August 18, 2023. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2023070013.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
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 3,828 vehicles this is a bigger campaign than 72% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2022 to 2023, so the oldest vehicles on it were one model year old when the defect was reported to NHTSA.
Mercedes-Benz vehicles have been recalled over the electrical system 50 times before this, most recently in March 2023 as 23V204000. That is not evidence the earlier repair failed.
This site holds the complaint record for 6 of the 8 model years the campaign names. Their owners have filed 123 complaints with NHTSA, 23 of them before this campaign was filed. 31 of those name the electrical system, the system this recall is about — a count of complaints, not of this defect. The earliest of them reached NHTSA in February 2022, 1 year before this filing.
The vehicles on this campaign carry 21 other recalls published here, the newest being: 25V533000 (steering), 25V366000 (back over prevention), 25V255000 (electrical system), 25V150000 (wheels).
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 May 2, 2023 as campaign 23V309000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
