NHTSA Complaint #11699506 — 2021 JEEP WRANGLER

While driving at highway speed on November 11, 2025, my 2021 Jeep Wrangler experienced a sudden and complete electrical failure without warning. A “Battery Saver Mode” message appeared, and within seconds multiple safety systems began shutting down. First Failure: While driving on the highway and exiting, the vehicle abruptly lost power steering, ABS, stability control, airbag system, exterior lighting, dashboard displays, and engine power. Multiple warning lamps illuminated at once. Steering and braking became extremely difficult, creating an immediate safety risk. I was able to coast to a stop and park. The vehicle then appeared stable and the messages cleared. Second Failure: After restarting the vehicle, the warning reappeared. While driving on a major high-traffic roadway, the vehicle experienced a total electrical shutdown in active traffic and would not restart. Third Failure: A towing service attempted to jump-start the vehicle; it briefly powered on, illuminated nearly every warning light, then immediately shut down again with the radiator fan running at full speed. The electrical system continued to collapse and the vehicle required a full tow. Inspection and Diagnosis: The dealership confirmed a complete alternator and charging system failure at approximately 36,419 miles. This failure occurred at only 4 years of age, which is unusually early for an alternator or charging system failure. The vehicle’s original battery also failed unusually early (at only 2.5 years old) without warning, which may have been an early indication of a charging system issue. The vehicle is lightly used, garage-kept, never off-roaded, and regularly maintained. The sudden loss of steering assist, braking assist, airbags, lighting, and engine power at speed and in high-traffic areas created an extreme safety risk for myself and others. This appears to be a premature electrical system failure and may relate to broader charging system concerns reported in similar vehicles.
