NHTSA Complaint #11489685 — 2019 CHEVROLET BLAZER

Initially received Stabilitrak dash warning when brakes were applied for longer than 30 seconds (ie., stop light) for several days with no SEL. Then, while driving along a secondary highway at approximately 60mph, all dash lights lit up, power steering failed, power brake assist failed, and vehicle started stumbling. Pulled to side of road and vehicle shut off. Performed restart and was able to complete drive home (approx 3 miles). Upon arrival and shutting off vehicle, all dash lights illuminated then shut off. Vehicle would not start after (no click, no turnover, indicating failed battery). Attempted to charge/maintain battery but battery charger indicated sulfated battery. Multimeter showd 7.5V. Replaced battery and car started normally but all computer functions were reset to factory defaults. The failure of the power steering and brakes due to a faulty battery is an extreme safety issue. The fact that the battery is only 3 years old and internally corroded to the point it can't be charged is both disappointing and an additional safety hazard.
