Prius (2004-09) :: 2006 - Runs Poorly Only In Hot Weather When First Started
Jul 12, 2014
I am the original owner of a 2006 Prius with 98,000 miles on it. Three summers ago it developed a problem where on very hot days (well above 90 degrees) when first started it runs very poorly. It starts normally and has no trouble light come on. It does this even though the car may have sat in the sun for hours and the engine/cooling system is relatively cool. But for the first 5-10 minutes it hesitates and stumbles with acceleration (as if it had bad gas). In fact at first I thought it was a bad gas problem. It never actually stalls.
It does this with or without the air conditioning on. It runs fine the remainder of the year and runs OK when first started if parked in a garage or a shady area on a very hot day. I have replaced the spark plugs, air filter, oil & filter numerous times, & changed the transmission fluid-but still this problem persists summer after summer. The traction battery fan is always on from initially starting the car every time this problem occurs. Could this be a battery problem? And if not, what then?

2006 F450 6.0 that I've owned since new. It has had 2 injectors replaced previously, EGR cooler with BPD, and a few other problem parts. As it is getting older, I have recently noticed it runs like absolute dog crap when it is cold. It can't even reasonably accelerate onto the hwy when cold. Once it is up to operating temp, it runs better. It still does not pull like it did when it was new and under 50k miles...but it is at least driveable once warm. I need to do some heavy trailer towing soon and need to get this thing back to accelerating good. What should I be looking at first for the horrible running condition when cold?

I recently replaced the plugs cuz I had a rough idle all the time. During plug change when I discovered they had already been changed I found one that had a burned off electrode. Does this mean a lean condition exists?
After plug change it runs smoothly but only after 10 min warmup in our canadian winters. I can drive it when its not warm but seems to have less than full power and idles very badly after driving w/o proper warmup.
Next I changed fuel filter and checked fpdm, it was a little rusty but not bad so i just mounted it 1/4 off steel to prevent further rusting.
Since then I have installed a programmer [diablosport] but found no codes since i had battery disconnected for filter change. no new codes in last few weeks since.
So do I have a lean running cylinder causing this poor cold idle or a rich cylinder? It must be a clogged or dripping fuel injector right?

For the past couple weeks on the way home from work the ICE runs non-stop for 20+ miles. My drive is 25 miles and the weather has been 105+. In the morning everything seems to work fine. In the afternoon even with the AC off, battery almost fully charged the ICE does not shut off at all even at a stop. I even tried putting it in EV mode and it tells me Not Currently Available. My Prius is a 2012 3 with 5500 miles. Is this normal in hot weather or is there something wrong??? Also the mileage sucks, in the morning with the AC on, weather around 90 I get 55-58mpg. In the afternoon I get low 40's even with the AC off.

Have a 2007 and everything was running fine all day today. Stopped at home for a few hours and went back out to run a few more errands and my truck started running poorly, dashboard lights were dimming, and the ESC OFF & ABS dummy lights came on as well as the red battery light. Managed to turn around and make it back home. Sounds like my battery needs replacing? Hopefully its just the battery and not the alternator.

Have a 2006 F350 5.4l that is mainly used as a plow truck. I drive it at least once a week when not plowing just to make sure it runs ok, etc. Only put on about 2,500 miles per year. Keep it in good repair - not by me, but by the dealer or mechanics.
Problem - last two times I started it, it started ok but runs real rough for about ten seconds. Sounds like the engine is going to die. After about ten seconds, it "catches" and runs normal. Have no problems when driving it. If I restart it, it doesn't do this, so it seems to only happen when the engine is cold.
Battery was brand new back in Sept. All plugs were replaced maybe 3 years ago, as was the cat converter and muffler. Run non-ethanol fuel. What might be causing it before I bring it in.

06' prius that I believe to be abnormal behavior. Just took the car on a 360 mile round trip. After about an hour of driving (Interstate 78mph) I happened to notice on the Energy screen that the car started to use the electric motor steadily for about 5 minutes of driving on flat terrain (Kansas). I watched as the SOC went from 5-6 bars down to 1-2 (purple). At which time the car started experiencing bouts of high rpm on level terrain/small hills. It stayed in this state for over 20 minutes or so of driving. It acted like it knew it needed to charge the hybrid battery, however the level never increased until such time as I exited the interstate and started braking. I am assuming that the HV battery should rarely discharge that much traveling at highway speeds on flat terrain.

2006 prius. Yesterday gave a jump to a friend with a motorcycle. After I got back in the car, no electricity whatsoever. Jumped my prius using another car, started fine and drove home, no warning lights. Same thing though after turning the car off, no electricity at all, can't start it.
Eventually figured out that I had blown the 120A fuse, so replaced it and the car starts fine now. But... I get the triangle with the exclamation point, and the car with the exclamation point on the mfd. What might be causing this? Battery reads 12.5v with car off. I find it a little strange that I didn't get any warning lights when I jump started it, but do now that it starts from its own 12v battery.

My 2006 Prius (156K miles) has recently started bucking and jerking when the ICE engages or disengages. The worst is if the car is stopped (brakes or in park) and the ICE kicks in (for instance if the A/C is running) - it will make the entire car jump. But it also happens in the normal course of driving, most often when the car is coasting for awhile and then I accelerate out of the coast - there is a noticeable jump as the ICE engages.

I have a 2000 Honda Accord LX V6 auto with about 125k on it.It seems to me that when I'm going downhill for example - so I am not giving it gas - it feels like its running rough - sort of. It kind of feels like the brakes are being applied then released, applied then released.Now, once summer arrived and I had to start using the AC all the time, after the car was warmed up and having run for 20+ minutes, it would REALLY start running rough. I watch the tachometer and it bounces up and down. When I turn off the car for awhile like to go into the grocery store, when I come out and try to start it, it wont. It just cranks but wont catch. If I do manage to get it to catch, it stalls. I have managed to get it to catch-apply the gas and pop it in to drive and make it home, but something is obviously very wrong and I don't want to get stuck somewhere. I have a code reader and the car has not produced any codes.

I have a 2004 F-150 crewcab, 4.6L with 118,000. I don't drive the truck often but for the past few months its stalls and cuts off, and idles poorly in reverse. Truck cutting off at low RPM's, low speeds, and after going over some bumps. At one point the engine light came on but now it is off and I am still having the issues. . . . not sure what code it would display. I have been reading articles and blogs and most say the TPS, MAF, or IAC is the problem.

My Chysler Town and Country started fine on a morning when it was 9 degrees. (no garage, so it was out in the weather.) I let it run for a couple of minutes so things would begin to thaw and then I drove to work. It ran really rough. I figured that once it warmed up, it would smooth out, but it did not. Even after the weather warmed up into the 50's 5 days later, it still runs rough. Now, I am also getting a check engine light. What could be wrong?

My 2006 Prius battery runs down regularly overnight. It seems to be something connected to the immobiliser and/or the interior lighting.

The CD drive motor has started to run continuously. Nothing will make it stop, other than shutting down the whole car, and even then it runs for a while longer. Is there a fuze somewhere that I can pull? My guess is that the CD player (which still works) would have to be replaced and that doing that is several hundred dollars. Our Prius is 2006.

So, I noticed after the week long heatwave (using Priidash and the Prius display) that during normal driving (under 65mph and slow accel) that my prius is NOT keeping the battery at 60% SOC....It is staying in the low 50's or as low as 39.5%....If I go above 70mph, I see the battery being drained and not recharged at all....I reset the battery (twice) the first time it made no difference but the second time the car turned on and said I had 60% SOC when in reality before the ECU reset I was at 49.5%. I know my battery is good because I have stress tested it many times. Its in great shape. The only thing I've done differently these past few weeks is I left the car in Park with the AC on 75 auto for about 5hrs on 4 different days....Its a 2004 Prius.

"Vehicle with smart key system: The indicator light flashes after the "POWER" switch has been turned OFF to indicate that the system is operating." I have noticed that my immobilizer light will not blink when it has the no start issue. usually when the key is out the light blinks but when it won't blink.... it won't start.

I just got a 2005 Prius, it is getting about 40-43MPG in 50F weather. This is my first time with a hybrid, much less a Prius. Is this normal for this car in this weather, or does something seem wrong.
The 12V seems to be getting about 11.7-11.8 under load.
Tire pressure is about 33PSI, going to increase it most likely from the sounds of other people having it higher.

My 2004 Prius is due in the shop Tues for a hybrid battery replacement. Codes indicate only one cell bad BUT...It is obviously having some problem running. We were very low on gas yesterday but wife filled it before she came home.
She parked it in garage. The Hy Batt indicated all green bars. She may not have pressed the Park button before Power - I do that a lot too.
This AM I changed the spark plugs before I tried to start it. I then started it (ICE & started-sounded OK) and backed it DOWN the driveway into the street and started down the street. The ICE stopped.
The batt indicated one blue bar so the batt would not propel it. After trying a couple times to make it run, I disconnected the 12v grd and let it sit for an hour. Then I reconnected the batt and the ICE again started showing hybrid at 4 blue bars and stopped after a few seconds. Tried it once or twice more, same thing.

It has been cold recently (out of the past week, highs in 20's or lower). This hasn't been as much of an issue before, but in the past week I have had the red triangle of death, brake warning light, check engine light, and VSC light all come on at the same time, three separate times. Also, the display screen shows a red outline of a car with "!" through it. Each time this has happened, the lights didn't come on as soon as the car was "Ready" but only after the gas engine was running for a minute or two.
The first time the lights came on, I was driving back from class, but after I got back to my house I did some internet research and saw it may be a low oil indicator. Checked the oil, it was almost at the bottom mark on the dipstick, and it had been over 10,000 miles since the last one (oops! we don't normally do that). After reading some stories online, I took it in to get an oil change, and the lights went off for a couple days. Second time the lights came on, I checked the oil level, it was definitely over-filled, so I took it back to Walmart and had them redo the oil so that it was at the right level. I checked the oil level before leaving the parking lot that time and it was at the top mark on the dipstick. Again, all the lights were off for a couple days.
Today, I drove my car for about an hour in the morning (temperature was around upper teens, wind chill below 10) and had no problems. Then, this evening I turn the car on and start driving out of the parking lot when the car beeps at me and flashes all of the warning lights again. I drove back to my house and it is now sitting in the driveway. I am not planning on driving it until I can have a car mechanic friend take a look at it on Tuesday, but he doesn't know anything about the hybrid system/battery.
My wife and I have also noticed that since the weather has been colder, the hybrid battery (shown on the "Energy" screen when driving) seems to be charging and discharging much faster than normal. I haven't seen it at only 1 bar or full of green bars more than a couple times in the 2.5ish years we have owned the car, but in the past two weeks it has happened 5-10 times (estimated). I am not sure if this is due to the weather, or if it could indicate a problem with the (hybrid?) battery. For obvious reasons, this makes us nervous :/
As a side note, I changed the transmission fluid sometime in December, so I was wondering if possibly I didn't put enough fluid back in. I have checked the diagnostic screen and found some codes, but most of them seem to relate to the audio, which doesn't concern me as much as the code that seems to indicate the transmission, which is why I mention the change I did a while back. I just don't know why it wouldn't have shown up until now. I'll attach some pictures I took tonight of the codes and lights.
Also, the battery is a couple years old, but after sitting for a couple hours the battery was reading 12.1 V according to the diagnostic screen, so I don't think that is the issue. We haven't had any trouble getting the car to start, and once it is running it still seems to drive normally with the warning lights on. What these codes mean, and a possible cause for the warning lights?

I think this happened last year. Whenever it happened, I know it's happened before. It only happens when it's cold outside. Yesterday, it was 18ºF which, Priapus was happy to show me, equates to -6ºC.
