Vsc ABS mil lights came on in dash and brakes sank to floor, but restored control after restart. Checked diagnostic codes and it showed codes for hybrid battery P0A80 and P3025. Replaced auxilary battery with oem from Toyota. Now car shuts down while in motion driving highway speeds without any warning and lose gas pedal response. First time it happened with my family in the car including a 5 yr old and 9 month old baby. Complained to Toyota as vehicle only has approx 93000 miles and Toyota declines to assist with resolving issue even though warranty was extended to 10yr/150K miles. Dealer misdiagnosed vehicle codes. Brakes failed second time, this time causing car to slowly bump into object and scraping bumper at low speed. Checked all fuses. Vehicle now continuously shuts down randomly on slow or high speeds, while making a turn, merging into traffic, crossing a heavy intersection.

The hybrid battery overheated according the mechanic at the dealership. The mechanic stated that other hybrid batteries have had the same problem because of a defective filter at the front of the car, which allows debris and dirt to get into the compartment that houses the hybrid battery. It is a $3,900 cost to replace the hydrid battery since it is no longer under warranty with 200,000 miles on the car. The mechanic stated that Toyota had modified the new filter to stop the debris and overheating problem, and that the new filter would not allow debris in. Since Toyota was aware of the filter allowing debris into the hydrid battery department, and modified the new filter to resolve the problem why was I not notified to replace the filter before it allowed the battery to overheat the hybrid battery to be destroyed?

The hybrid battery overheated according to the shop of the dealer. According to the mechanic this is not a new problem with the car. The warranty is 8 years or 100,000 miles on hybrid battery. The mechanic stated that the front filter allows dirt into the hybrid battery compartment, which results in the overheating. It is a $3,900 cost to replace the hybrid battery. The mechanic also states that the new filter has been modified in order to not allow the debris to get into the hybrid battery. If Toyota was aware to the point of modifying the filter in order to prevent the debris from getting into the hybrid battery area why didn't they tell me that the filter was defective and needed replaced to protect the hybrid battery?

While my wife was driving the car a warning ("check vsc system") appeared in the status screen and about a minute after, another message appeared ("check hybrid system"). then, the car stopped running. The impulse allowed for driving the car to the road side. Tried to power it back without success. It was required to tow the car home and then to the dealership for diagnostic. Prior this incident there were no previous warnings or signs. Update: Today received communication from the dealership that diagnostic test confirmed that the problem was the hybrid system inverter module and that has to be replaced.
