2023 Mercedes-Benz EQB 250+ problems

Filed Oct 15, 2026 · Brakes, Driver assistance · FL

My 2023 Mercedes-Benz EQB250 (VIN: [XXX]) is currently sidelined at Mercedes-Benz of Pompano with a dangerous High-Voltage system failure that causes an immediate cascade error of the Electronic Stability Program (ESP) and vehicle braking systems. The technician verified the codes match Mercedes Service Bulletin LI42.45-P-079407 for an HV DC/DC Converter defect and matched my serial number to the bad batch. The vehicle simultaneously carries an active Federal Safety Recall for an internal High-Voltage Battery Pack explosion/fire risk (the federal safety agency Campaign 26V073). Mercedes-Benz USA Corporate (Case #[XXX]) and Service Director Hayden Smith are actively refusing to honor the 8-year/100,000-mile High-Voltage warranty on this converter. Furthermore, the dealership is threatening to charge me 'late fees' to strip away alternative loaner transportation. They are actively attempting to force a consumer to either pay $5,800 out-of-pocket for a warrantied high-voltage component or drive a compromised EV powertrain that violates the manufacturer's own outdoor parking safety mandates, as the owner resides in an apartment complex with an enclosed underground garage.

The rear liftgate glass (backlite) of the vehicle shattered spontaneously while the vehicle was parked and unoccupied inside a closed parking garage on 09/30/2026. There was no break-in, no impact, no vandalism, and no warning lamps, messages, or other symptoms prior to the failure. The entire tempered-glass pane crazed and partially collapsed with no visible point of impact, consistent with spontaneous tempered-glass failure caused by a nickel sulfide inclusion, a documented glass manufacturing defect. The failed glass is being replaced through the owner's insurance by Safelite AutoGlass. The selling dealer, Mercedes of Seattle, declined to inspect the vehicle and stated they had never heard of such a failure; the problem has not been inspected or confirmed by the manufacturer, a dealer, or an independent service center. Although no one was injured because the vehicle was unoccupied, the same failure while the vehicle is occupied or in motion could shower occupants with glass fragments and eliminate rearward visibility. The complainant asks the federal safety agency to investigate whether this indicates a glass manufacturing defect trend.

BATTER RECALL FIRE SAFETY: I have a 2023 Mercedes-Benz EQB 250+ affected by the federal safety agency safety recall 26V073. Mercedes has acknowledged that the high-voltage battery can fail internally and cause a fire. I’m instructed to charge only to 80% and park outside away from structures, and Mercedes’ latest remedy requires replacement of the entire high-voltage battery. This is already a low range vehicle and limiting to max 140 miles on interstate before having to charge 45 minutes is a nightmare. I need to drive between states for work and this is just simply not feasible after doing so for months without a solution. The first recall was March 2025 with no fix.
