Occasionally is dead when I get in it. It takes a few minutes, then everything back to norm. Took to dealer and they said 12v battery is still at 75% +. I tightened connections on battery but still doing the same thing once in awhile. Anyone else know what may be wrong? 66000 miles on it and has been flawless until now. I am the original owner.
do the brake lights come on when you press the brake pedal? might you be pushing the power button too quickly before pressing the brake fully? did you tighten the negative to body connection as well? lastly, dealers don't understand 12 volt batteries. take it to auto zone or other for a free load test and print out, if you don't own a volt meter
A two won't have a power button. Plain old steel shank twist key. Rodent intrusion? They love to eat wires. Wear and tear on the keyswitch? unusually heavy keychain? Just spitballing.
Correct. No push button. Swapped keys with wife but still having same problem occasionally. Posted via the PriusChat mobile app.
Have you done (or had done) any testing of the 12 volt battery. In ascending order of effective testing: 1. (assuming your year has the under-hood jump point) Leave the hood ajar overnight (to avoid any "wake up" of the car) and in the morning measure the voltage of the battery with a digital multimeter. The under-hood jump point is fine for this. Post what value you get. 2. Assess the battery with an electronic load tester. There are DIY level versions (Google Solar BA5 or BA9, a couple of the options. Most battery retailers will have a pro-level tester and will test for free. Dealerships also have them, will charge a bit though. With these you hook up directly to the battery posts, input the type of battery, the rated Cold Cranking Amps (stock batteries tend to omit this value. If you can'f find it, try 325, it'll be close), then run the load test. It'll tell you the measured CCA, and give a verdict, if the battery is vaiable and so on. All that said, considering the age, it'd be a good time to just replace it.
