If you’re the type of Mercedes EV driver who already checks the range estimate more often than your bank balance, we’ve got news that won’t help your blood pressure. Mercedes-Benz is advising owners of certain EQB electric SUVs to cap charging at 80 percent—not to preserve battery health, not to optimize efficiency, but because charging to 100 percent could, in engineering terms, trigger a “thermal event.”

In plain English: the battery could short-circuit and catch fire. And unlike a check-engine light or a rattling trim panel, battery fires tend to command your full attention—and the local fire department’s.
The good news, such as it is, is that this recall affects a vanishingly small slice of Mercedes’ EV fleet. Just 169 vehicles are involved, including 100 EQB 300 4Matic models, 48 EQB 350 4Matics, and 21 single-motor EQB 250s. That’s barely enough cars to fill a Costco parking lot, though that’s cold comfort if yours happens to be one of them.
If this sounds familiar, it’s because Mercedes has been here before. Earlier in 2025, the company recalled more than 7,000 EQBs in the U.S. for—you guessed it—fire risk, issuing the same temporary advice to keep charging below 80 percent until a software update could be applied. Déjà vu, now with fewer vehicles.
According to Mercedes, the newly recalled cars are “early-stage” 2022–2023 model-year EQBs. Later vehicles supposedly received more robust battery hardware, sparing them from this particular drama. For the affected cars, the company says drivers will likely get warning messages if things start getting spicy under the floorpan while driving. Unfortunately, a parked EQB could still ignite without so much as a polite heads-up.
Naturally, you might assume Mercedes would replace the suspect batteries with improved units. Naturally, you’d be wrong. The fix is—again—a software update, scheduled to roll out via dealerships in early 2026. Until then, owners are stuck playing battery-management limbo.
That’s especially painful given the EQB’s already modest range. The dual-motor EQB 350 carries an EPA rating of just 227 miles on a full charge. Knock that down to 80 percent and you’re looking at roughly 180 miles. Add a sensible buffer at the bottom end of the gauge and real-world usable range could shrink to around 150 miles.
That’s enough to visit relatives across town, but probably not across the state—unless you enjoy spending quality time at freeway charging stations, contemplating life choices and scrolling through apps that insist your charger will be available “any minute now.”
For now, Mercedes EQB owners affected by the recall can take solace in two things: first, the odds of being impacted are low; and second, Mercedes insists the fix is coming. Eventually. In the meantime, charge cautiously, park thoughtfully, and maybe keep the holiday travel plans local.
