NHTSA Complaint #11532894 — 2007 TOYOTA PRIUS

When the 12-volt battery in this car dies, there is NO warning light to indicate the battery is dead or is running low. The driver is given no warning or indication prior to the car being disabled. Once the battery dies, the vehicle immediately decelerates, there is no acceleration, the braking system becomes mostly disabled, and the power steering is not functional. The car becomes disabled, while being driven, without warning. When this event happens, there is a high pitched screaching alarm, and the majority of the dash lights turn on. None of which indicate there is an issue with the 12-volt battery. The large red triangle light with the exclamation mark comes on, as well the lights indicating that there is a problem with the brakes. Additional dash lights also turn on during this dangerous event. The rear view monitor screen states that there is an issue with the transmission. The reality that a minor 12- volt battery is responsible for disabling a vehicle is extremely dangerous, especially since it happens when the car is being driven. This is a serious issue. Toyota must include an indicator light that warns the driver the battery is low prior to the car being being disabled. Please investigate this matter, as it seems to be a common problem, based on online research. My safety was in jeopardy due to the fact that I was driving the car on a main road, with moderate traffic, and lost control of the car as it became disabled. To get my car off of the road required the assistance of several good Samaritans who used their bodies to block traffic in order to get the car out of the flow of oncoming traffic. Fourteen days later, after the battery was replaced, and the car serviced/inspected, I drove the car 10 to 15 miles, wherein the car did the same thing. Per the dealership, the issue was not the 12- bolt battery. Thank you for your time and consideration. Kindly, Cynthia Becker 623-209-4290 [email protected]
