Prius (Gen 3) Fuel :: MPG Decreased Rapidly In Two Weeks
Sep 16, 2012
In the last 2 weeks I get 60MPG (indicated) with ease on my 22 mile round trip all city work commute. The commute is very predictable with the same speeds and driving technique and similar light pattern.
The thing is, the most part of the summer I had to work hard to get upper 50's on the same commute.
No, I don't use AC as the temps are mild enough to drive with windows down in early morning and evening.
There are 2 variables: the ambient temp went down to low 80's rather than high 80's before.

I have a 2012 prius c with 72k miles. When i bought the car, it took a while for the fuel economy to increase. i drive 100 miles a day at 85mph and topped out at 52mpg. pretty damn good, if you ask me. im all interstate with very little city driving.
2 years later, its time to get new tires and ever since i changed them, my fuel economy has decreased to 45mpg.

I used to get really good mileage on my 12.5 mile commute, if I didn't reach 50 miles per gallon, I considered it a poor commute. But over the last several hundred miles, I have only averaged about 45 miles per gallon - sometimes I'm not even reaching 40 mpg. I checked my tires, they are fine. I also notice that the gasoline engine is running a lot. I'll be at a stop sign, and the battery is nearly full, but the gas engine is running.

i've noticed on my 2008 prius that once i lose the first bar of gas i begin to rapidly lose the rest. For example the first bar might take three days to vanish but once its gone i might lose the second bar on the same day i lost the first.

I have an '06 Subaru Forester (4 cyl, automatic) with about 97,000 miles on it. For the past 5 years I've had the car, it's been getting roughly 26-28 mpg on average. Within the past 3-4 months, though, the fuel economy has dramatically decreased. Now, I'm lucky if I get 21 mpg. (I used to be able to get almost 350 miles per tank, and now if I make it to 275 I'm jumping for joy!)
I took my car to the shop for the 90K service, and they didn't change the fuel filter as a part of that service. (They did replace the coolant, replace oil & filter, replace spark plugs, replace differential fluid front & rear, replace brake fluid, replace auto transaxle fluid, and then they did a bunch of inspections on belts, hoses, brakes, etc.)
I took the car back to the shop after this service so they could change the fuel filter, and they told me that because of the type of fuel filter I have, it should last the lifetime of the car. This sounded a little fishy to me, so is this true?

Had the ole factory fuel separator/bowl drain start leaking on me about a month back. So i ordered and installed a new one, issue fixed. Well last night the fuel leak started again, I looked everywhere and i cant see anywhere else it may be leaking at. I felt the underside of said piece and it didn't feel wet, but the valley is full of fuel.
I got in there and tightened the 4 bolts down some more, they were tight but i got a some turns on em and am hoping i either didn't tighten it down enough or they maybe backed out some. Now just gotta see if that solves the problem, again.... the replacement is a doorman, the o-rings were bigger/thicker than the factory orings on the old part, of which the o-rings were shot.
Like I said once i replaced the part the leak stopped for 3 weeks until last night. If the tightening of the bolts doesn't solve it where should I look next? I have an FRX mod but i checked all that and its dry as a bone around all the fittings by the bowl and the heads. No indications of leaks anywhere around any of the FRX assembly.

My 370,000 mile 2001 has been relegated to being parked at the Metro station to get me from the train station to work. I only use it about once a week now, and haven't used it for several weeks because I was away on vacation etc.
I checked on it today just to make sure its still there and hadn't been vandalized, etc. (fortunately, no issues on that front). However, when I start it up (started no problem), it ran ok for a bit, then seemed to run rough intermittently, then ultimately, the ICE shut off and the warning lights all came on.
I was able to drive it around the parking lot on battery power alone, but the ICE never started. I didn't have my (non-prius aware) code scanner with me, so I tried resetting by disconnecting the battery for a minute or so. That allowed the ICE to start again, but it did the same thing again.
When I was briefly able to see the MFD energy display, I could see that the traction battery is only showing about 25% SOC.

I used to fill up with gas without shutting the car down, because I didn't see a need for it. I would disable the fan on the climate control every time to avoid having the ice come on as I refueled. I figured that because the ice wasn't coming on, I wasn't breaking the law. I've since changed my mind about this, after reading posts here on Prius Chat. I also recently noticed on the last few fillups that it seems like the gas capacity on the bladder has decreased significantly.
I used to be able to refuel the car when it was down to a single flashing pip and put 10.5 gallons in with no problem, and without overfilling. I have always been careful not to overfill. However, it seems like now I can get only 8 gallons in at the most. The capacity has decreased with the colder weather, however I used to be able to get 10 gallons in on a consistent basis without overfilling even during the winter.
Is this reduced bladder capacity a result of damage to the system, or is this normal? I have probably filled the car up about 100 times since I've owned it (odometer is around 50K now) while remaining in the ready mode.
Is there anything I can do to expand the capacity of the bladder back to normal, or will I have to live with this? Although it's annoying, I'm not going to spend the money to replace the fuel tank unless it's truly necessary.

I have a Prius i-Tech 2007. I had gone overseas and came back after 2 weeks. On return, the smart key just didn't work. It didn't open the door...I took out the mechanical key and opened the door. Then I inserted the key in the key slot and tried to start the car but it just didn't react at all.

I parked my car (outside) and went on a business trip for three weeks. When I came back last week, when I turned the car on, the brake light and the ABS light were on. And it hasn't turned off since.
The car was working fine and didn't show any sign of troubles prior to me parking it, no funky light was on. What could be the cause? It wasn't driven during three weeks. What could have deteriorated to cause these lights to come on? The car seems to be braking fine.
FYI, before getting to my car last week, after leaving parked for three weeks, I mistakenly pressed the Panic button. And I didn't realize that the Panic button got stuck and was continuously in circuit. And it stayed like this for an hour before I realized what happened and fixed it. Not that I think that it can have an influence on my current problem, but thought I would mention it anyway...

I was on vacation during march first week and my 2006 prius didnt start after that. I do not have the smart key with me and have only the manual key. I just called the Toyota as it is a certified vehicle, they tried jump starting but it did not work. Does the car needs the Smartkey to be inserted in the fob? I have it in my city where i live 200miles away. (parked car in my friends place). If it does not need smart key in fob, does the 12v battery is dead?

If I park the car at the airport for 10-14 days, do I need to disable the remote key fob? I could not find any information on this in the manuel. I have a Prius 2014.

I'm still trying to decide whether to get a Prius. I'm looking at a 2014 new III. Question: My friend who has a 2001 Prius (whose original hybrid battery is still going strong, by the way) says that if she does not drive her Prius for 2-3 weeks, her starter battery will need a jump. Is that particular to Priuses, or do all newer cars with the keyless entry and/or theft deterrent do that?

My 2010 Prius with 72k miles on it. I bought a OBDII scanner and read P0401 Exhaust Gas Recirculation Flow Insufficient Detected. The check engine light comes on for few days, then go away for few weeks and then come back again. It's been doing the exact same thing (Come on for few days and then go away) in last few months. But I do not feel any different in terms of driving.

We are newer to hybrids. We purchased a used 2012 prius approximately 1 year ago. Within the past year, we have replaced the headlights approximately 6 times. Last month we replaced both front lights and tonight, out of nowhere 3 lights burnt out (both headlights and 1 bright light). It was dark outside and we live in a rural area so we had to drive 90 miles with 1 bright and the 2 day time lamps.
We maybe have changed bulbs in other vehicles once every couple of years and this is a monthly thing with our Prius. They aren't cheap so it's frustrating. My husband has been changing the bulbs and he does not touch the glass.

Last 2 weeks my 2006 HV battery seems to be showing the SOC very erratically. Going up and down fairly rapidly, sometimes staying at 4 bars for a good 20 minute drive on the highway. This weekend after driving 7 hours in 110 degree heat, the battery fan came on. It was blowing on high for about 15 minutes and then it quieted down.
I believe these are signs of it's potential upcoming failure. The car has only 127k miles so I'm still in warranty. So fingers crossed that I'll be close to home when I see all the warning lights pop up.

I was driving down a stretch of freeway that sloped down, took an exit, and rolled to a stop at a red light. The traction battery indicator was at full. While waiting for the light to turn green, the ICE would come on for a few seconds, turn off for a few seconds, turn on again, doing so for the minute or so until we started moving again. What was happening.

Just bought a 2010 Prius with 48k miles. I'm noticing what feels like a slight slipping when rapidly accelerating, or that's what I would call it in any other car. It's barely noticeable, and my only concern is if this is the beginning of a transmission issue.

I want to say that I love my prius but I am having an odd (although minor issue).
When I accelerate a I hear a noise (it sort of sounds like a cricket rapidly chirping, only a lower pitch or maybe a phone on vibrate).
What this could be?

I recently was stuck in a traffic jam in the middle of the Mojave desert. Outside temp was about 102 and we crept along for maybe 15 minutes going no more than 5-10 mph. I had the air conditioning on. I noticed the power bars were rapidly disappearing and got worried that I would lose the battery if I didn't get moving. Needless to say, I finally was able to speed up and the bars came back. (dropped to 2 bars).

I just get a hand of a brake blinkers module that when you connected parallel to the brake lights it will blinks and strobes like emergency vehicles. When brake is pressed, the brake lights blinks rapidly and strobes random pattern. It gives more visibility instead just stay on.
