Do not top off your ID.4 to 100% until official service updates are performed at a dealership.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Timeline and Next Steps<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>June 17, 2026: Volkswagen ordered detailed examinations of complete high-voltage battery systems after preliminary data flagged potential risks linked to isolation-resistance values and DC fast-charging ratios.<\/li>\n\n\n\n<li>September 21, 2026: Field study results confirmed that certain charging profiles paired with a state of charge over 80% could trigger thermal events. Additional technical analysis was requested from the battery supplier.<\/li>\n\n\n\n<li>September 23, 2026: The Product Safety Committee formally authorized a voluntary safety action for all affected U.S. vehicles.<\/li>\n\n\n\n<li>November 27, 2026: Official warning notifications explaining the safety risk and temporary charging limits are expected to reach owners by mail.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Quick Reference Summary<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>NHTSA Campaign Number: 26V-630<\/li>\n\n\n\n<li>VW Campaign Code: 93EX<\/li>\n\n\n\n<li>Affected Population: 2023\u20132026 Volkswagen ID.4 (22,524 units)<\/li>\n\n\n\n<li>Affected System: Electrical System (High-Voltage Battery)<\/li>\n\n\n\n<li>Primary Safety Hazard: Thermal propagation \/ Vehicle Fire<\/li>\n\n\n\n<li>Temporary Precaution: Cap battery charging capacity at 80%<\/li>\n\n\n\n<li>Interim Notice Date: November 27, 2026<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Volkswagen Group of America has launched a safety action affecting 22,524 model-year 2023\u20132026 Volkswagen ID.4 electric vehicles due to a hazard involving high-voltage battery fires.&nbsp;&nbsp;If you drive an affected ID.4, there is a simple setting you need to change in your touchscreen charging menu immediately while Volkswagen works on a permanent fix.
