I lost all my keys and had to call a local locksmith. He wasn’t able to program a new key, could get lights to turn on dash and everything, so he called another locksmith to help. After trying, the second guy told me that the first locksmith had somehow deleted all the key information and caused an ECU-related issue. He couldn’t get the lights on dash to light back up

I ended up having the car towed...

I drained the radiator and then the engine block and only got a few dribbles out of that, basically the tube I attached filled up but not much more.

I ran in maintenance mode until fan came on and it's still full so now I'm confused, why did it only take...

I am in the middle of replacing the 16363-21060 motor for the radiator fan for a 2014 C one, it's a bit tricky because the A/C radiator shares the same plastic base at the bottom that also supports the radiator for the engine.
If you pull up the engine radiator, the A/C radiator also comes along. Also the A/C radiator metal tubing interferes with pulling up the assembly composed of the fan & engine radiator if you simply move the A/C radiator forward.
I think two people are needed...

I’m working on my own 2016 Prius C (NHP10L). It took a hit in the front and the frame rails are now… let’s say “not factory spec” (photos attached).

I brought this car from the US for my wife, so I’m trying to bring it back to life instead of turning it into garage art.

This is a DIY project, a friend let me use his garage, and I’m doing my best to fix it properly, not just eyeball it and hope for the best.

Right now I’m stuck because I can’t find proper frame dimensions or...

Ive been driving the car for the past 5000km while turning the abs back on by jiggling or reconnecting the skid motor connector on top of the abs pump because that's whats telling the pump to shut off.

the abs pump works fine it holds the pressure. But i believe its an electrical or fuse issue with the relay. so ive replaced the abs fuses Abs...

My daughter has a 2012 Prius C with about 110,000 miles on it. She bought it used with one previous owner. The vehicle looks like it was relatively well maintained.

When should you replace the strut coils on it? Is there a set maintenance timeline or miles for it or is it only when you see cracks in it or do you measure the height of the ride?

Also, how often do you change the strut?
