According to filings with the National Highway Traffic Safety Administration (NHTSA), an internal battery defect may lead to a <strong>thermal event and potential vehicle fire \u2014 whether the vehicle is parked or being driven<\/strong>.<\/p>\n\n\n\n<p>If you own one of the following models, your vehicle may be affected:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>2023\u20132024 Mercedes-Benz EQB 250+<\/li>\n\n\n\n<li>2022\u20132024 Mercedes-Benz EQB 300 4MATIC<\/li>\n\n\n\n<li>2022\u20132024 Mercedes-Benz EQB 350 4MATIC<\/li>\n<\/ul>\n\n\n\n<p>The recall is listed under <strong>NHTSA Campaign Number 26V-073<\/strong> and replaces earlier recalls <strong>25V-050<\/strong> and <strong>25V-894<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is the Safety Risk?<\/h2>\n\n\n\n<p>Mercedes has acknowledged that certain battery cells produced during an early production period may not be sufficiently robust. Under certain production and usage conditions, an <strong>internal short circuit<\/strong> can develop within the high-voltage battery.<\/p>\n\n\n\n<p>If that occurs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A <strong>thermal event<\/strong> may result<\/li>\n\n\n\n<li>There is an <strong>increased risk of vehicle fire<\/strong><\/li>\n\n\n\n<li>The fire could occur <strong>while driving or while parked<\/strong><\/li>\n<\/ul>\n\n\n\n<p>If the event occurs while driving, drivers may see a <strong>high-voltage battery malfunction warning message<\/strong> in the instrument cluster.&nbsp;&nbsp;If the event occurs while the vehicle is parked, <strong>there may be no warning at all.&nbsp;&nbsp;<\/strong>That lack of warning is particularly concerning \u2014 especially for vehicles parked inside garages or near structures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Caused the Problem?<\/h2>\n\n\n\n<p>Mercedes-Benz identified deviations in the battery supplier\u2019s production process. Certain battery cells from an early production range were found to be:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Less resistant to stress factors over time<\/li>\n\n\n\n<li>More vulnerable at <strong>high state-of-charge (SoC)<\/strong><\/li>\n\n\n\n<li>Potentially susceptible to short circuiting \u2014 especially when combined with:\n<ul class=\"wp-block-list\">\n<li>Charging infrastructure influences<\/li>\n\n\n\n<li>External damage<\/li>\n\n\n\n<li>Environmental stress<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p>The risk appears elevated when the battery is charged to high capacity levels.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Chronology of Events<\/h2>\n\n\n\n<p>The recall began on January 31, 2025, when Mercedes-Benz filed an initial safety notice with NHTSA and later implemented a global software update in April 2025 to reduce the risk of battery-related thermal events. After additional incidents were reported outside the United States in May 2025, the recall was expanded, with a supplemental notice filed in October 2025. In November 2025, two fire incidents in Europe involving vehicles that had already received the software update raised concerns about the remedy\u2019s effectiveness, prompting further investigation and discussions with regulators. Extensive testing and analysis conducted between December 2025 and January 2026 ultimately led Mercedes to conclude that the software update could not reliably eliminate the risk in all affected vehicles. As a result, on January 30, 2026, the company launched a new recall requiring full high-voltage battery replacement for certain vehicles, now identified as NHTSA Campaign Number 26V-073.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Fires Reported in the United States<\/h2>\n\n\n\n<p>Mercedes reports:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Two fire incidents in the United States<\/li>\n\n\n\n<li>Both vehicles were part of the original recall scope<\/li>\n\n\n\n<li>No U.S. fires have been reported after the software update<\/li>\n\n\n\n<li>Approximately 74% of affected U.S. vehicles have completed the original recall repair<\/li>\n<\/ul>\n\n\n\n<p>However, because the software update\u2019s effectiveness cannot be fully confirmed, Mercedes is now requiring <strong>battery replacement<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Owners Are Being Told to Do<\/h2>\n\n\n\n<p>Until repairs are completed, owners are advised to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Park outside and away from structures<\/strong><\/li>\n\n\n\n<li><strong>Limit charging to 80% battery capacity<\/strong><\/li>\n\n\n\n<li>Await official notification letters (interim letters expected February 27, 2026)<\/li>\n<\/ul>\n\n\n\n<p>Importantly:<\/p>\n\n\n\n<p>Vehicles previously repaired under recall 25V-050 or 25V-894 <strong>must still undergo the new repair<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Lemon Law Implications<\/h2>\n\n\n\n<p>Battery replacement is not a minor repair. It is one of the most expensive and critical components of an electric vehicle.<\/p>\n\n\n\n<p>If your Mercedes EQB:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Experienced a fire or thermal event<\/li>\n\n\n\n<li>Has been out of service for extended periods<\/li>\n\n\n\n<li>Required multiple repair attempts<\/li>\n\n\n\n<li>Is subject to repeat recalls<\/li>\n\n\n\n<li>Has diminished value due to safety concerns<\/li>\n<\/ul>\n\n\n\n<p>You may have rights under your state\u2019s Lemon Law.<\/p>\n\n\n\n<p>Even if the manufacturer ultimately offers a repair, repeated safety recalls involving fire risk may qualify the vehicle as defective.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final Thoughts<\/h2>\n\n\n\n<p>Electric vehicles depend entirely on battery integrity. When the manufacturer acknowledges that a software update may not be sufficient \u2014 and ultimately requires full battery replacement \u2014 that is a serious development.<\/p>\n\n\n\n<p>If you own a 2022\u20132024 Mercedes EQB and have concerns about:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Safety<\/li>\n\n\n\n<li>Repair delays<\/li>\n\n\n\n<li>Diminished value<\/li>\n\n\n\n<li>Buyback eligibility<\/li>\n<\/ul>\n\n\n\n<p>It may be time to speak with an attorney experienced in automotive defect and lemon law claims.\u00a0\u00a0Safety recalls are meant to protect consumers. But when defects involve <strong>fire risk<\/strong>, the legal and financial consequences can be significant.\u00a0\u00a0If you believe your vehicle may qualify as a lemon, you do not have to navigate this alone.<br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Owners of certain electric Mercedes-Benz EQB models are now facing a serious safety defect involving the high-voltage battery.
