NHTSA complaint #10915498, filed 2016-10“Our Buick Verano 2012 did not pass inspection last year. When the battery was changed, the date and time went back to that when the car was made. The date and time were adjusted to true date and time. During inspection, the malfunction indicator lamp was on all the time while stationary & in motion. We were told to drive it a long distance to clear itself. It cleared & it passed inspection after driving it for hundreds of miles. Then the not even one year old battery started draining itself without reason because the lights are on automatic. We jumped it when not home and charged it when home. …”
