Hybrid System Malfunction

Over the past few months, my Prius 12 V battery has been giving me some issues. The tag died and we haven’t been able to afford to renew it, so we don’t drive it unless it’s an emergency. However, I try to start it every couple days and take it around the block. I would just replace the battery, but they’re not super cheap…

I’ve been able to charge it every time with no problems, but the past couple weeks it got cold and then life got busy and I wasn’t able to start it like I needed to.

I finally got it charged today and when I started it, it said “Hybrid System Malfunction” and my check engine light came on.

I can get my brother in law to check it out tomorrow night, but I have an emergency situation in the morning and I need to drive it.

Am I cooked??? Or will I be okay to drive it 15 minutes there and back???

It’s a 2018 if that’s any help.

Missing relay ?

I was just doing some routine maintenance when I decided to look in my relay box for the first time owning this vehicle and it looks like there are two unoccupied slots for relays based on the diagram on the lid.

Is anyone familiar with these in particular, any assistance would be grateful.

'09 Prius spare tire sizing question

Hi All,
Thanks for all the great support you all offer here. Having this forum to post and learn is really invaluable for someone who is not a huge car person. 

I have a 2009 Prius and long story, but the spare tire got pierced while in the compartment so I am in the hunt for a new one. The OEM spare is T125/70 D16. There is nothing wrong with my wheel. It seems expensive to just order a new tire and have a tire store put the tire on the wheel - they want $160 which is crazy. There is someone selling a spare tire never used from a 2009 Elantra that is T125/80 D15 for $25. Does anyone know if this will work on an 09 prius? I searched but haven't found anything conclusive and getting confused about it all. The size seems super close and both are 5 nuts. Any thoughts? Thank you!

SRS red airbag light on code B1650 '09 Prius

Hi All,

My red airbag light has been on forever and it's kind of driving me crazy. Any mechanic I go to just says they can't fix it, I should go to Toyota, which I'd rather not because who knows how much they would charge. It's the occupant classification system fault. B1650. It is the passenger seat, as whenever someone is in the seat, the passenger airbag indicator continues to say off, even when the seatbelt is buckled. The driver side sensor seems to work fine because it starts beeping if the seatbelt isn't bucked. Does anyone know which scanner would help me fix this, or have any other guidance? I tried car scanner app, and dr. prius. They both won't help with SRS airbag issues. Also, I have never been in an accident which sometimes throws the seat sensors, and I checked the connections under the seat and they seem fine. Thanks for any help!

I bought a prius 3rd Gen

If the battery is full on the gauge, i press EV mode it only lasted 10 seconds. I did some Googling and a post said its normal, i was skeptic and got an obd2 reader, did a life expectancy battery test on dr prius, but 3/4 of the way it stopped said bad obd2 but i still got results, but is that normal it says that? I use a obd2 viecar

2016 Prius C One, 99.5K, $10K. Advice wanted!

I've Googled as much as I can and searched the threads on here, but hoping to find folks with experience with this specific car.

It'll mostly be for errands around the city and a few road trips here and there. I'm petite in size if that's helpful info.

Questions:

How long do the hybrid batteries last? The private seller seems to think I'll never need to replace it, the internet says it should be replaced around 10 years, which would be very soon (and several thousand dollars that I don't have).

Any recommendations for backup cameras or hubcaps? How about for glass-break alarm systems (lots of break-ins and catalytic converter theft in my area)?

What are some other small tidbits you know about these?

Really happy to have my Gen 3 back after driving rentals - what small things do you appreciate?

I have a 2015 Gen 3, got rear ended (thankfully lightly) and I was driving 2023 Hyundai rentals for a couple of weeks.

The first one was an Elantra, then the horn randomly stopped working (apparently a known recurring issue, this was such a bad first impression of the brand to me 🤨) so I got a Venue, this compact SUV. Both were nice new car with new features, and it was interesting to test drive them since I’d only tested Toyotas before.

But I just really missed my Prius the whole time despite it being older and slower to accelerate lol.

  • I have a sun roof (sorry moonroof - I realize this is a fancy name for continuity purposes to add to the spaceship feel 😆)
  • I really love the furry fabric of the seats. I can’t handle the newer plastic fabric. I think this is why I’ve never felt like I needed seat warmers.
  • The horn is also louder/more assertive with a Prius/ Toyotas.
  • I feel like my Prius heats up faster maybe having a more compact front? The boxy Venue was definitely colder

I wasn’t used to the Elantra being this lower sports car and I actually bruised my shin on the protruding control panel part getting in. And the Venue felt cheaper and more utilitarian like a toy or something haha but it was interesting to be higher up.

Things I did like:

  • It was awesome to have new car things, like the CarPlay screen and heated steering wheel & seats.
  • It felt like the steering wheel was looser and easier to turn, could be that Toyotas are kinda stiffer on purpose? Or a new cars are just like that?
  • The brighter white headlights - after that, I changed my Prius to the halogen (?) ones since the default is sooo dim and orange.
  • Also the reverse parking lines/guide were helpful.
  • The music stays on until you open the car doors.

I’m sure others have experienced this contrast too. What things have you noticed/appreciated about Priuses when driving other cars? I’m not even a diehard fan but I appreciate my car more now 😌

Prius Windshield Issue

2018 Prius Prime, around 60K miles. Maintenance light came on for routine maintenance, took it to a Toyota dealership where I routinely do business. This was last Monday the 17th.

Today, Monday the 24th, had a very early appointment where I left home around 5:00. It was raining heavily, and I noticed that my driver side wiper wasn't really working that well. It was still dark when I arrived at my appointment. When I came out of the appointment, I noticed a white piece of plastic that was covering my driver side wiper. I removed this and further discovered that my windshield now had fine scratches on the driver side. The part of the white plastic piece facing the windshield had the texture of emery cloth, and it had been moving back and forth over my windshield for more than an hour. When the blades were replaced, the mechanic neglected to take the cover off. I did not see the cover due to the darkness of the time during my drive.

Went back to the dealership and things became complicated. The manager would like to see if the scratches can be polished and buffed out. I'm thinking new windshield. Need constructive advice on how to move forward here.

Hybrid system check light came on and went away

Hello, my Prius today gave the yellow triangle with 'Check hybrid system park vehicle in a safe place' after starting it up from a parking lot. It was running fine before and there were no signs of any malfunction during driving. However when I moved it to another parking lot, shut it down and then restarted it, the light went away. Should I be concerned?

Finally getting some decent MPG again

I'm basically doing 50/50 highway and city driving. Since October I was getting about 5,5l/100km even though it wasn't really cold. This continued throughout to December up until now. I'm not really driving any differently than I did those months before and there wasn't an oil change in between or any service at all. Now that I get about 4,3l/100km even though it's freezing is a bit odd.

Also it's a 2010 with currently 232.700km

2015 Prius plug in. Code C1214. Can't find much online. Anyone have experience?

I went to go look at a 2015 base model Prius plug in version with about 130k miles

Seller says Bluetooth doesn't really work and there's a few quirks here and there that might be surface level signs that there might be underlying issues.

I took my sidekick blue driver and the code C1214 popped up. I tried to YouTube this and I kept getting videos in india.

There's other similar codes not but C1214

It could be anything from the brakes not getting bled properly to the AbS actuator going bad to something about bad rotors or brake sensors?

Does anyone have any experience with this code?

Also I didn't even know the plug in came in a base trim which sucks.

Auxito Inquiry | 2010 Prius Low Beam Headlight

My right-side low beam headlight went out.

I want to buy an Auxito brand because I have heard rave reviews. The thing is, in all pages I see on Amazon, they refer to their lights as "fog" lights, not "low beam" lights.

For those of you that have a 2010-2012 Prius and have an Auxito low beam headlights, could you tell me which one you bought? Does it work perfectly for the low beam light?

Thanks!

2017 Prius Prime MPG

Hello! I got a 2017 Prius prime with ~118k miles on it this past weekend. Yay! It is currently showing an MPG of 24. I haven’t gotten the chance to fully charge it yet, or drive it more than ~30 miles, for that matter. Is this a normal MPG for the year/miles, or should this be addressed? Will it change as I drive it more? For context, I live in a currently cold New England state. Thanks in advance!

2009 Prius 200k Milestone!

Finally hit 200k (on the odometer, had to replace the capacitor so my high score will always be a little off)

All DIY repairs listed below:

Inverter Coolant Pump Brake Pump Brake Pads (drums were still good) All wheel bearings Head/Tail lights ATF drain and fill Oil changes HUD capacitor Cabin filter Reupholstered center console lid with leather and new foam

So far the hybrid battery seems to be good and still averaging 40MPG. Any other recommendations for maintenance? I may have forgotten some things in this list too.

Also, might just be me misremembering but after reinstalling the dash the AC airflow seems lower and the fan sounds like a lot of air is just blowing behind the dash. Anyone experience this?

2024 prius as a goal?

Hi :D

I know this question has definitely been asked but I wanted to ask the same question.

I currently drive a 2009 Mitsubishi outlander that has about 75k miles driven and it works perfectly, but I intend to give this car to my brother in 4 years when he's old enough to start driving

I'm interested in the prius due to the fuel economy and small size, and seems to be more simple compared to other cars.

Would it be a good idea to try to save up to buy a prius in cash for the next 4 years?

Financial situation: Just assume the average college student.

Head Gasket Replacement, Engine Replacement, or Sell the car?

Hi! My 2012 Prius Plug-in shows signs of the head gasket leaking coolant with a cylinder 1 misfire code tripping occasionally when subjected to back-to-back days of heavy traffic.

The car drives fantastically aside from the occasional cold-start rattle. It has new spark plugs and a recently cleaned EGR and intake manifold; additionally, the car does not burn oil, nor do I see any oil-coolant mixture after changing the oil. As for coolant, the engine coolant reservoir doesn't seem to drop much when I drive in town, but on my frequent 300 mile trips on the interstate, about 30% of the visible coolant reservoir will have depleted.

I bought this car for $5,000 and have driven it for 7,000 miles and it has 270,000 miles now. The previous owners serviced the car its whole life and even cleaned out the egr valve and intake manifold in its lifespan (I cleaned the egr valve and intake out and noticed someone had already been there before). I was also informed that the vehicle is currently on its second hybrid battery.

My concern with this car is if I replace the head gasket, I worry that I'll still eventually get problems due to the high mileage of the vehicle. In contrast, if I put another engine in, I worry I'm putting too much money into a high mileage car. The pricing of my options are as follows from some mechanics in my near-ish area,

- Head Gasket: $1400

- JDM Engine Replacement: $3100

- DIY: I just worry about destroying something, but am not opposed to it.

Alternatively, I could also just try to sell the car and search for something else, but it's tough knowing there just aren't really any cars that can compete with the prius MPG in this price range.

age vs miles buying decision

Hi everyone,

Buying my first Prius in SoCal. At about the same price point, I can get a 2018 with ~70,000 miles on it, or a 2020 with ~100,000 miles.

If it was a conventional car, I would go for the lower miles. From the reading I've done, people seem to say that for used hybrids battery age matters more than the actual mileage. Does that hold up in this specific case, everything else being equal? (clean title, one or two private owners max)

Which one would you buy?

Best Air Freshener?

Just bought my new Prius a few weeks ago. I want to keep it smelling fresh.

Since then I’ve:

  1. Bought an insulated food bag for when I pick up takeout.
  2. Plan to take the car in once every month or six weeks for a thorough interior and exterior cleaning.

But I still haven’t figured out the air freshener situation:

(A) I used the clip coupons in my old car, but I saw in the archive that it leaked within someone’s Prius and ate up some of the plastic. So that’s a no go.

(B) I’ve done the charcoal bags in other cars, but they can also leave some residue if you leave them in one place for too long.

(C) gel beads get messy and are a pain to continually refill

(D) the jars of wax that supposedly absorb odors are not that effective from what I know.

How difficult is it to replace body panels on the 2004-2009 Priuses?

I was unfortunately in an accident a little over a week ago, and while all of the inner parts of the car seem to be fine (brought it to a mechanic to get it cleared), there's damage to the front bumper and the passenger side fender, and the headlight brackets snapped. I want to preface this by saying I don't need the car to be pretty- I'm a grad student, so money is tight right now, and my main concerns are safety and passing inspection (I'm in Delaware). Local auto body shops seem to be set on trying to sell me parts that (from what I can tell) aren't necessary- for instance, they want me to replace the lower grille, which is completely undamaged, and the hood, which only has superficial damages. (I don't mean to come across as dismissive, I know that these people have much, much more experience than I'll ever have, but I also know that unfortunately as a woman in her 20s, there's plenty of mechanics who do try to take advantage of my assumed lack of knowledge.) So, to anyone who's done this type of replacement before- how difficult would you say it was? Did you need any tools outside of what the average person would have around? I have the repair manual, am going to look for used parts at some local scrap yards, and have a friend with some basic auto maintenance/repair experience who's going to help me- is there anything else I should know or keep in mind?

Help

2007 Prius has p0172, p0300, p0302, and p0420. I've replaced the ignition coils, spark plugs, fuel injectors, catalytic converter, and mass airflow sensor and battery but still getting these codes. I'm at my fuck wits end, I can't sell it cause I'm also living out of it

2010 Prius Headlight replacement - $20 for one - other options?

I bought a headlight from autozone (Sylvania Basic Headlight Bulb H11). It was $20 after taxes for one and not really that bright. Where do you get your lights and how much does it cost? Best place to buy?
