2005 Prius Won't Turn On After Shutting Off

Hello Prius Chat,

I recently just bought my ‘05 Prius from a small dealership with 233,000 miles in May of 2019 which it came with a rebuilt battery. I could tell that mostly everything on the Prius was OEM, so I had to replace the tail lights, signal lights, tag lights and also the side indicator lights since some of them were burnt out.

When I started to drive my car, everything was running great. After a week of buying the car, I drove home and parked the car in my driveway. I click the push start button to shut it off and it immediately shut off. Usually after clicking the start button to shut it off, it would take like half a second to shut off completely so I found this kinda of odd that there was an immediate shutoff. After trying to start it again by clicking the start button, it didn’t start which I was pressing the push start button multiple times. I even tried locking and unlocking my doors and they didn't even do that. My key didn't even work to lock the doors as well. Then after about 1 minute, it just automatically turned on by itself, but was not "fully started." What I mean by not "fully started" is that you can only access the AC and the radio so you couldn’t drive it. Eventually, I pressed the start button again and it started up the car, and it started running again like nothing happened. This "immediate shutoff" also resets the digital clock in my car as well.

Is this because I need to replace the spark plugs? Or something different? I tried to find any sort or research on this problem but couldn’t find anything. This has happened multiple times to me now within 4 months of owning my Prius so I kind of figured this was a problem.

 

I’ll check on that and get back to you. Thanks for replying!

 

Alright so after the rainy weather has passed around my area, I finally had the time to check the 12V battery since I’m in college without a garage and just a parking lot. It did seem fine to me, which I did disconnect and reconnect all the cables just in case they were loose and what not. The car seems to be running good so I do think it was just the white connectors that were loose. Thanks for the advice PriusChat mates! I’ll let you guys know if this ever happens again!
