NHTSA Complaint #11427483 — 2009 ACURA MDX

The battery has been drained on three separate occasions this year (2021). I replaced the battery after the first occurrence. Each time I have had to use a battery jump to restart the vehicle which sufficed to get it operating and return home. On the last occasion, the car started to display dash board warning messages before arriving at home after driving only 15 miles. This came with a fully charged battery installed to get the car restarted. Previously I could see no error codes, but following this latest incident the AWD error code 77-01 is displayed by an OBD reader. The vehicle began to run roughly and flashed many dashboard warnings as the battery began to draw down to zero power. Latest incident required a battery replacement instead of just a jump to restart.
