Prius (2004-09) :: CEL Coming On And Turning Off - Getting 8 To 12 Mpg On Local Roads
Jul 31, 2011
I have a 2005 Prius with almost 219000 (!) on it. It runs great, but about three months ago the check engine light started coming on and turning off by itself. I had a scan done on it and they mentioned possibly a bad O2 sensor. Friday, I was on the highway and the master light (big red triangle with ! in it), the VSC, and the yellow ((!)) brake light came on. I pulled over, shut the car off and turned it back on. The master light and check engine light was still on. The VSC and yellow ((!)) light came back on a few miles down the road.
I pulled off the highway and took it to a mechanic who scanned it again and said that there were several codes that came up including a large exhaust leak.The car was running fine and I had to go to work on Saturday overnight, so I drove the car. Other than the lights, nothing seemed wrong. However, the lights would turn on and off intermittently and I was getting horrible mpg (8-12 mpg on local roads). On the way home, the car seemed to stall (clearly not a manual though). The power steering cut out and a message saying something like transmission parking brake malfunction ( I couldn't read it all because it went away).
I was only about .1 miles from home, so I shut the car off and turned it back on. Not another 50 feet and the car "stalled" again. This time, I couldn't get it to turn off or anything. I left it running and unlocked (though I took the key with me) and waled home to use a phone. I called AAA and went back to the car. I put the key fob in the keyhole and tried shutting the car off again. This time, it shut off so I turned it back on and slowly drove it home. Any thoughts?

I've had this intermittent plastic rattle coming from the back end on bumpy roads at low speed. It's not the license plate and bracket (already fixed that one). Yesterday I happened to tap on the outside of my left tail light and heard it rattle with the same noise I'm hearing on the inside of the car. There is no rattle when I tap on the right tail light.

I notice that if I use AC, the battery drains a lot faster. If i do not use AC, I see my battery stays at one bar from full on flat freeways or local streets.
If I use AC, I see the battery goes down quickly to 2 bar from full just on local streets.
So AC drains the battery quite a bit. Does ppl use their AC all the time or not?

So i am trying to diagnose my vibration/noise that i am getting from the front right side of my 08 prius (176k miles). It kind of like a rattle vibration when driving on fairly smooth roads. I jacked up the right side to take a look around to see if anything is out of the ordinary. I did the push pull around the tired to see if there was any motion (there was none). Although there is some play when you manual rotate the wheel, about and inch of circumferential motion. Is this normal ?

My AM band is not sorting out the local stations like the FM band. 1070 is a rather well known Indy station , but it doesn't appear on the available station list. In fact, only one of the stations on this list had signal and it was rather weak. When switched from list to tune, local stations could be found. Is this normal?

I noticed not too long ago that when I drive my car after being idle for a long time, the gear acts weird. Bought the car in July 2015 and has only 2,600 miles on it.
Usually in S or S+ mode the gear doesn't go past 5th gear on local. However, in Auto mode it goes up to 8th gear when I am not even accelerating that hard. In manual shift mode, the gear is delayed by about 5 sec, using the paddle shifter. It happens once and it goes back to normal.
I have not talk to the dealer yet. I wanted to get a proof before I do, so they dont tell me nothing is wrong with the car.

I have had this error come up in the past (P0441) and have reset it. At one point I replaced the purge flow valve.
Lately, when I'm running at expressway speeds I have no issue. When I get off the expressway and get into stop & go local street traffic, the error will appear again, sometimes. Recently, in the past 3 weeks it has done this 2 times in this stop and go driving scenario..
I've been keeping the gas tank above 1/4 tank, to make sure pressure stays up in that system. Even passed the emissions test where they clamp the gas gap with their machine to make sure it's holding pressure. What could be going on with my 1999 V6 passat?

Why does my Volvo 850 (1994) continue to shut off? The fuel pump and filter have been changed as well as having the gas tank cleaned. Car runs good but occasionally shuts down while driving on highway and local driving.

This morning i've been to toyota to do the regular service and to try to find that what is creating this noise on my front end ,they removed brackets etc and lube anti roll bar bushes and top mounts as best possible. Still the noise is there. We recreated the noise this morning by circling around at full lock multiple times . They said that if the lube would not solve the problem it could be the struts mount.

My wife's 09 Sonata SE AUTO 4-cycl.. I drove it last weekend and discovered a strange noise that can be heard after driving for a while at normal local road speeds.
The sound is like a combination of a whine and something that sounds like radio static. It can be heard very easily with the radio off and stopped at a red light. However, this sound also exist while the car is in motion. It becomes more difficult to hear as the road noise increase.
When I shift from D to N while stopped or driving, the noise immediately goes away. When I shift back to D, it sometimes comes back.
The consistent pattern seems to be that the noise will occur after having driven for a while at a consistent speed of at least 30-40mph. If I drive around the neighborhood for a while at low speeds and then stop, the noise will not be there.
I have not made effort to hear it from the outside of the car.

Is there a way to pop the trunk without turning the car off, releasing the key from holder, getting out and opening it from outside. This is probably a terribly stupid question but I've recently discovered this oddity and thought I'd ask -no matter how simple it may sound.

I've got a 2007 Prius (Touring Edition) that has almost exactly 150,000 miles now. It's had a few issues (leaking water pump, bad HID bulbs constantly...), but those were nothing I haven't been able to fix myself. Moving forward...my car is turning at least all of it's electronics on by itself.
I first noticed an issue when randomly I would come out and it would be dead. So I'd jump it, and it would do fine for a while. Over the past two weeks though, it's been happening a lot. Until 3 times now I've walked by it and the radio was loudly blasting the default station. It's powered up, A/C on, radio on loudly to a default station, and all the stations on the radio and clock are reset.
Before I get told I'm not turning it off properly...I am. I have been insanely thorough on my procedures after the first time, and I actually make sure all lights are off, radio is off (even just the power of the radio), and A/C is off BEFORE I go through the proper procedure of turning it off and then locking it with my key from the outside. I even put my key on the hanger and go out and check that it's locked and off after doing this.

When making lefts and I think rights I can feel the power cut out sometimes. It's always done it so I was thinking it was normal. I was wondering if there is a cv joint that could be wearing out, but it would do it all the time versus just turns I would think.

I have a rattling problem with my 2011 Prius and Here are the quick facts:
The rattling typically happens while going over bumps or driving on patchy roads. It happens when running over the "buttons" on the road.
The noise is not related to RPM, or transition from battery to engine usage.
If I had to describe the noise, I would call it a "plasticy" buzzing/ticking.
It definitely sources from the driver side dashboard. Passengers cannot hear it well.
This is a video of the rattling.
I have tried pressing down on various panels, none seem to eliminate or dampen the sound completely.
However! Smacking the light-gray panel below the "triangle window" use to temporarily reduce the noise.
I've tried removing the same panel below the driver side "triangle window" because I thought the noise was coming from there but it persisted.
I read on another rattle thread that the column supporting the roof (and bordering the triangle window) is the real culprit, but punching it only reduces the rattle sometimes.
I've brought it into my local Toyota and they did a search for anything that could be rattling. They didn't work, and after they finished the center console was rattling too (which I've fixed).
Also, cold weather seems to worsen the symptoms. I should also state that sometimes I have little to no rattling, but on other trips there is no end to the rattling.

My new Prius C is only 6 weeks old, but started hearing some annoying rattles from the dash area when driven on rough roads (tarmac or roadworks).

Experiencing a rattle from the moonroof area when on slightly rough roads or any other time? If so what did you do?

Prius has taken on a new habit. When making turns at any respectable speed, there's a very noticeable knocking sound. I've had the windows rolled down and can't tell whether it's coming from the right side or the left. I'm pretty sure it's coming from the front.
I just put him up on blocks and rolled under to check out the front suspension, turning mechanism and anything else I can see. It wasn't long before I realized what I'm looking at nor am I likely to recognize any problems if I saw it. Having said that, nothing looked broken or dangling.
He's due for a 100,000 mile check-up. Since I'm heading to the dealership, it would be easy for me to have them look at it.

I understand the engine turns on and off frequently (coming to a stop it turns off, then when going it turns on). I have noticed that sometimes when at the stop it will turn off, then immediately back on, and off again, even with my foot on the break.

My 2006 Toyota Prius with 130k miles i had the 12v battery replaced 4 months ago because I had the dashboard not turning on when starting the car. I drive about 200 miles everyday for work (deliveries) so the car basically is turned on all day.
Last week when I got home turned off my prius when I turned it back on later that night the dashboard would not turn on. Tried disconnecting the 12v battery and still no dashboard. Drove around like that for two days until Friday when suddenly the dashboard turned on and everything was fine.
Later that night I turned on the prius and the dashboard didn't turn on again, shut it off and turned it back on, dashboard turned on.
Now the big issue: The ICE does not want to turn on. Vsc and abs lights with the triangle of death are on. Code reader wasn't showing any codes.
I towed the prius to my mechanic so I wouldn't get stranded with only the electric motor running, he checked the 12v battery, fuses and relays. Moving the car around on his lot they discharged the hybrid battery. At first there were still no check engine light and no codes. Now the prius is throwing the p3000 code.

My 2009 Prius headlights are turning off automatically while I'm driving. At first only one of them turned off, but sometimes both turn off.the fog lights remain on.when one goes off, its like it only goes half off. Then sometimes while the headlights are on and I used the right light the lights go completely dark. Why this might be happening?
