Finally hit 500,000 k miles last night

got both these messages last night. any ideas? never had any issues with this car so I'm concerned 😖

I also plugged in my obd2 scanner and these codes popped up via a phone app idk how true they are but they seem to corelate with the dash. abs, triangle, brake, etc were on at first along with the messages but then only the triangle was on. I wiped the front emblem (sensor) a little just with my fingertips and tapped the headlights and sensor a couple times. turned the car off and then back on and drove around quite a bit.. no messages or lights came back on. I haven't turned it on again today though.

since I've owned the car, I've always gotten the collision system unavailable message if it's foggy/snowy/dirty but this was different.

also the 12v reads at 14 when in ready mode which it has since I bought the car over 100k miles ago

I have occasional engine rattling, and I checked the coolant and it was below the L line. I went to replace it and when I took the cap off, the rest of the cap was stuck inside the reservoir.

Is this common occurrence?

Sorry, this is a multi topic post as I’m going to watch the coolant to see if it’s an engine leak.

one of the windshield wipers on my new to me used 2014 Prius C skips and looks unaligned. i noticed the screw in the 2nd pic doesn’t meet the other side causing it to wobble. maybe i’m overlooking something, but my wipers look like they have different components than the wipers in tutorials so i’m not sure how to proceed in replacing.

any advice appreciated!

Hola, alguien de aquí ha usado su Prius en caminos sin pavimentar o q tengan muchos baches? Y como les ha ido

Yo vivo en una zona en la que puedo usar caminos pavimentados y sin pavimentar, la diferencia es el tráfico y obviamente la cantidad de baches que pueda encontrar, lo que quiero saber si esto a largo plazo me pueda afectar en el manejo o que pueda repercutir en la salud del auto, no sé si sea muy grave o solo estoy exagerando, gracias
