Kia - Sedona :: Revving At Higher RPM Then Down To Lower Level After Few Minutes Of Warming Up
I have begun to notice that when I start my van each morning for the first time that it is reving at a higher RPM then it did back during the winter. During the winter it may have been around 1000rpms at start before lowering down after a few minutes. Now it is starting at about 1500 and then returning down to the lower level after a few minutes of warming up. Could the change in outside temps cause this?

I have a 2004 prius with 149k on it and can't seem to break into the 40 mpg range. I live in an area with some hills, but nothing too crazy. I have even had trips of 60+ miles on pretty flat freeways/highways/roads and have only hit 38 mpg driving with a very light foot, coasting down hills, coasting to stop lights and using cruise control. I have tried keeping my speeds low and just cant get great gas mileage. I am not sure what else to try.
In the past few weeks I have had the oil, transaxle and inverter coolant changed and the water pump was changed 15k ago. I also had the spark plugs changed, air filter and have new tires.
btw, I bought the car used a few months back and have been getting the same mileage since I got it. I have not noticed any improvement from any of the maintenance I have done.
2001 Lexus IS300. I got 17mpg with HARD driving
Prius (2004-09) :: Transaxle Hum When Reach 40 Mph And Higher - No Warning Lights?
I seem to have gotten a hum coming from the front end when I reach 40mph & higher. Todate, I have not gotten any warning lights, red trinagle etc, but wanted to see if maybe there were some codes thrown.
Lastnight, I put the front on jack stands & had my wife put the car in D & step on the gas while I was laying under the car. The noise is coming from the transmission where the axles plugin. My fear is I need a new tranny.....but if its a code related to the hybird system, I might be covered under warranty.
By the way, my Prius is a 06 w/ 108xxx miles. I changed the CVT fluid around 70xxx miles.
Prius (2004-09) :: Noise Like A Roar Or Drone At Higher Speeds
I have a 2007 Prius (now has 220K + miles) I bought used about 2 years ago with 150K miles. I finally got used to the car sounds so this is something new, or rather it's becoming louder and enough for me to question it. The car is still quiet at low speeds but this sounds like something related to how fast the car is rolling, not the engine acceleration. It doesn't sound like it's coming from the wheels. It's a low roar like sound, not high pitched and it sounds like it's coming from under the middle to front of the car as if related to perhaps the drive train. If I am up to 40-50 mph and just rolling (foot off the gas) down a long hill, the sound is there. It gets louder the faster I go. Could it be a transmission sound? I've always had manuals so this is my first automatic transmission car.

I found recently that my 04' Prius' engine easily goes higher rev than before (based on engine sound pitch). It happens mainly when cold start, go up hill. After warmed up and on flat road, it goes back to normal. Overall, still in great condition at 211K. MPG stays at 46 on meter when temp is around 45F with 50% highway drive at 100 miles/day. I suspect the serpentine belt slippery or something. What do you think? I think the belt is original. I bought it used at 104K.

I own a 2005 Prius with about 145,000 miles on it. I love it. However, I've noticed that lately, the vent in the back by the window will come on and make a lot of noise. Some research has told me that this is the air vent for the battery that is in the back, and usually comes on when the temps are higher and the battery is starting to get a little overheated.

This evening I had an interesting hiccup happen. Out of the blue the car would not recognize any function of the key fobs (both) inside or out. Recently changed batteries in the fobs and the red LED was coming on with button presses so those weren't the issue. But as I mentioned, the car wouldn't recognize the fob for any button press or proximity for unlocking/ignition.
There have been a few times where the fob right next to my phone would throw the car off, along with a few random scenarios where I had to be right next to the car for remote lock/unlock to work. I figured this was some type of interference as all the occurrences seemed random.
Anyway, after nothing working I tried the fobs again and they worked as if nothing happened before. So, where the car possibly resets or in some way refuses to acknowledge the key fobs for a short time.
Prius (2004-09) :: AC Stops Working After Running For About 30 Minutes
My wife has recently been complaining that the AC will work for a while, but then it stops working after running for about 30 minutes. She also reports that, at that time, the air flow (blower speed?) seems to drop tremendously. I have observed the former but not the latter, so I can't say for sure that if it really drops in air flow or if it's just a matter of perception. I put my AC gauges on it and it reports the following:
Static reading is 70/100 PSI
Reading system on is 17/145 PSI
Ambient temperature is ~92 degrees humidity is 65%
Vent reading is ~77 degrees
I can see movement in the sight glass while the vehicle is running. I'd like to add a little refrigerant (if that's what it looks like it needs) just to see if we can make it through the summer. Prior to the AC problems popping up.
Prius (2004-09) :: Noise After Shutdown Occurred For Like 5 - 10 Minutes?
Yesterday my 2008 Prius with 95,000+ developed a new noise after turning it off and it has me a bit worried. I took an audio sample? Last night it occurred for like 5-10 minutes. Now today I went to turn it on and before I even pressed the power button it made another noise that I've never heard before which I didn't get on audio. It turned on fine, I let it run for a few minutes and then shut it off and the noise I got on audio occurred for several minutes. The noise comes from the driver's side by the electric motor. The clip should play in iTunes or Winamp, took it on my iPhone so its kind of low in volume.

OK, I finally resolved the bad skid control ECU, so I have no more codes relating to ABS sensors or pump actuator. Still get a C1310 when travelling at speeds over 60 for 10 minutes or so. After the car sits for a while, the idiot lights, triangle, ABS and brake lights disappear and the car runs fine. Except it has been whining at acceleration and deceleration a bit more than I remember. When I hooked up Tech stream, I got a P0A2B which is - Drive motor "A" temperature sensor circuit range/performance. Please tell me it isn't transaxle. Why does it only happen at high speeds? I can drive for 20-30 minutes around town without it triggering the dreaded red triangle.

View 2 RepliesPrius (2004-09) :: 2007 - Driver Side HID Cuts Out After A Few Minutes Of Being On
I've got a 2007 Prius Touring and have been experiencing that well-documented issue with the HID. Namely, the driver side cuts out after a few minutes of being on. If I flip the lights off and on again it will come back, but will inevitably go out again.
Last summer, I removed the assembly and dumped out about a half a cup of water, and drilled a small hole to create air circulation to dry it out completely. That didn't solve the problem so I did more research. I just replaced the ballast (which was corroded as hell), and that didn't solve the problem either (to my great disappointment). I found a salvage yard that has the whole assembly from a 2008, and I'm about to try that. If even that doesn't work, then I guess it has to be a shoddy power supply from the car, correct? And, in this situation, what can be done, if anything?
All I've been able to find are folks who replaced the ballast, or who fell into the extended warranty period that Toyota so graciously enacted back in 2011 (needless to say, my car does not meet their criteria anymore).
Prius (2004-09) :: Super Loud Whine From Engine Bay For About 10 Minutes
Yesterday while on an 50 mile I had much more serious whine from the engine bay for about 10 minutes, that I think was from the serpentine belt. I wasn't driving, but my driver (my gf) called and I could certianly hear it on the phone. I could hear it in the cabin, then I could hear it from outside the car. She opened the hood and said it seemed to be coming from the passenger side down by the firewall, engine side. I could hear it while driving and while she was parked and idling.
I'm not familiar with the prius engine bay yet but that area is where the fan belt is i'm guessing if its like my other fwd cars.
It was cold out. She was driving about 55 mph. She had already driven 45 miles when it started. It continued to whine like that while parked and idling, and also while driving. She started and stopped the car and it would start when the car was started. I'm sure she had the heat on the whole time so i can't tell you if it quit when the engine cut out, but i bet it would have.
Then after about 10 minutes it stopped. It started a little bit at start up and then went away. She drove home 50 miles and didn't notice it anymore. I drove it last night in 12 degree city/suburban driving/ highway for 50 miles and never had it come back.
Prius (2004-09) :: Hearing Single Beep About Every 4 Minutes While Driving?
I am hearing a single BEEP, about every 4 minutes, when I am driving. What the heck is it? I can't figure it out, looked in the Manual.
I found the Internal Alarm on Page 432, don't think it is that. The key is in my pocket, the car is on, I am driving! I've also removed the key from my pocket and set it on the front passenger seat, darn BEEP continues.
Prius (2004-09) :: Warming For 10 Minutes In Park - Battery Died
Last night during the East Coast's snow storm, I left my 2004 Prius warming for 10 minutes in park. I have a newborn and wanted the car warm for her. When I got back outside to leave, the Prius had died. The check engine light was on, but that was on before because I need to get the oil changed.
I went to jump start it, but when I opened the hood, I could hear that the engine seemed to still be running - it sounded like the belts were still going. So I was nervous to jump start it with the engine still seemingly on. I waited 30 minutes and that noise stopped.
When I tried to jump start it, I couldn't get the fuse box cover off after an hour of trying at 10PM, in the snow and rain. So I gave up and will try again later today.
Prius (2004-09) :: Traction Battery - State Of Charge Drops To Red In 20 Minutes
A month ago I bought a 2007 Prius with 140,000 km. I notice that the state of charge drops into the 'red' bars within about 20 minutes of the car switched on, in Park with no accessories running. A mechanic connected his diagnostic computer and saw 2 cells are low. However, the mechanic informs me there is no value in replacing those cells as others are likely to go down, thereafter. Is there anything I can do to avoid having to replace the entire traction battery?
