New 2027 Limited AWD Reservoir Blue

Got a new oem battery from a dealership in Phoenix for $1800 after a military doesn’t and installed it myself. Went from 48 mpg to 58. What a difference. The battery was 8 years old and still had life in it. I’m installing into another Prius that hasn’t driven in about 6 years… long story on that one. Can’t believe how much of a difference the battery would make in fuel economy but now I see. It’s like a brand new car!

For reference my 2004 Prius has about 360,000 miles on it. Found a cracked evap hose on the throttle body when I replaced it recently and cut it back, that brought the fuel economy up to 48mpg from about 42mpg.

Did the big project on my 2011 at 140k (cleaning egr and manifold, new OEM spark plugs, replacing pcv valve, map/maf sensors cleaned, etc) and all in all I was pleased with how smoothly it went.

Afterwards, acceleration feels a little smoother maybe but no extra pickup really, and the little rattle when accelerating after startup I had started to hear is gone, but after 350 miles of my normal driving I’m down 5+ mpg from a a stable average of 48mpg to 42mpg.

What’s the deal? Interested to hear any insights.

The egr and small manifold channels were completely clogged but I really got into the cleaning and I feel that they both went back in about as close to pristine as possible. No issues with reinstall at all. Tires inflated, same gas as always. The engine doesn’t necessarily sound any smoother when idling, but I think it’s just the normal Prius sewing machine engine sound that’s always a little weird. I was interested to see if there’d be a bump in efficiency after seeing how slammed the airways were, so I’m surprised to see it go in the other direction!

Grateful for the help of this sub, priuschat, and YouTube creators while getting through the initial project. Amazing resources available.

Hello, I bought one of the OBD2 adapters for a 2016 Prius 2 I found on FB Marketplace. It will be my first ever Prius, and I want to ensure I don't come home with a box that will fall apart soon, so I looked at a video for testing the battery, and something concerned and confused me.

In the video, it tells me to put the car on drive, and then FLOOR the gas and brake at the same time?! That sounds sketchy to me, you're sure that if I do that, a disaster won't happen and then I'd be arrested and fined a massive amount?? Sorry, I'm a worrisome person, I want to join the Prius tribe and ensure I'm getting a decent deal but that part makes me nervous, I need reassurance.

2020 Prius Prime with 33k miles. What is the best default “mode” to be in? When commuting ECO + EV? I’m still a little confused 🤔

Hi there! I've been a lurker for a while and really need solid advice. My car is a 2012 Prius at almost 160500 miles. For almost 3 weeks, my car begun making sputtering sounds and shaking for 1-3 seconds when in idle, at startup and when I push the gas. I took it to a mechanic, and they replaced both the spark plugs and coils, but it's still stuttering and shaking even though it's less than before. Not to mention my coolant severely decreased over the past couple days and noticed white smoke coming out of my car last night.

The engine check light hasn't come on yet again, but I bet it will soon. I did some research and worried it it's a head gasket or failing engine. I know it'll cost me $$$$ of dollars to get it fixed, but I'm also so close to paying off my car (about 2-3 months away).

Should I be looking for a new car, or should I put my money into fixing it again? I really want to keep it as long as possible but need advice from you pros. Thank you in advance!

Looking to upgrade to a new sodium ion pack but seeing theres a few different vendors. Who all has gone this route? Did you notice a good improvement? Any companies you wont deal with again?

Can anyone post a picture of a successful install of an Alpine iLX–W650 in a Prius Gen3, just so I can see how it looks? I'm thinking of installing one.

In my market I regularly see allegedly well maintained Prius’ in this year range for 3-4K. Usually with about 200-275k mileage.

I cannot afford much more than that and hate having a car payment. I had my telework revoked which, combined with the war and inflation, has caused my gas costs to explode, and I am desperate for a hybrid.

I have always been a Toyota guy, and have read good things about these model years of Prius.

What do you think I could realistically expect from a car in this year/mileage range in terms of longevity and probable needed repairs?

2026 Prius plug-in XSE w/ technology package

Wow - on my first cross state trip on the highway the Cruise Control, and Lane Centering were amazing and freaky. First the lane Centering was hard to trust when gojng through an area of construction with cement barriers on either side with a lane line on one side - I wanted to center between the 2 barriers not in the lane, like Prius did. Next there was a traffic jam, I never had to reset, it stopped me in the traffic then 8 or 10 mph, tgen zoom back up to cruising speed. During the traffic jam, I did get alerted several times to sit up, when I put my hand in the noon position on the steering wheel (this is s habit the car is breaking me of).

So what does everyone think of Safety Sense 3.0 and the Technology in the newer Prius models. This is my third Prius, 10, 18, 26, also had a Lexus hybrid in there.

I have a 2010 Prius, I’m driving one day and all the sudden all the lights come on, traction control, e brake and abs system, (tire light is dead sensors) (check engine is a cat converter issue) I’m just wondering if anyone has had this problem before and what was it that needed to get fixed, when I drive the breaks have to be used manually is the best way to put it, have to push harder on the brake, it’s not using the electric break system that charges the battery. I’ve been driving it like this for a year now because honestly I’m broke but the mechanic said it’s fine to drive but I’m over it, I’m just wondering what could possibly need to be replaced because once in a blue moon all the lights go away and the electric brakes work fine for a few hours, idk if something is broken, malfunctioning and just needs to be tweaked and not replaced entirely, my mechanic said it could be a few things like a brake booster or module system, don’t quote me on the names I don’t remember 100% what he said, if anyone has some insight it would be great

I hear people say it looks like a Tesla but i feel like if you’ve seen it in person it looks nothing like a Tesla.

After I bought a Toyota Prius Plug-in for around $36,000, I regret it — I live in an apartment and have no place to charge it. If I had ordered the Toyota Prius Hybrid instead, I could have saved around $4,000.*
