Hybrid vehicles may notice a rocking or surging feeling at freeway speeds of 70mph. Our technicians tell us new software is available for the hybrid powertrain control module to correct this concern.
The Check Engine Light may illuminate with code P0AA6 stored for a hybrid battery isolation fault. Our technicians tell us this may be caused by water intrusion into the high voltage battery case. The water may be a result of cracking body seam dealer above the rear door strut mount. Any water leaks should be repaired and the high voltage battery system inspected for water damage and repaired and dried as necessary.
