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.
Higher mileage cars can develop creaking and groaning noises in the front suspension, particularly when coming to a quick stop. Inspection and replacement of any worn parts should correct this concern.
The Check Engine Light may illuminate with codes P0171 and/or P0174 due to a lean running engine. Symptoms may include: Hesitation on acceleration, lack of power, and poor fuel mileage. This is commonly caused by a dirty mass airflow sensor. Our technicians tell us the sensor may be cleaned using an approved cleaner but replacement is often required to correct this issue.
A shift "lag" may be noted when accelerating from speeds of 10 to 20 mph. A software update for the transmission control module has been released which may correct this concern. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.
There are reports of intermittent failures with the heating and air conditioning control. The digital display might fail or the control might fail to switch between heater functions.
