Prius (2004-09) Fuel :: MPG Has Gone Down, Battery Behaviour Is Irregular

So my wife's MPG has gone down from mid- to high-40s to barely 40. We've taken it to the dealer and they run a check and said there was nothing wrong, adding that if there was something wrong with the battery I'd get a warning light, anyway.

So, took her car to get some gas for it and coffee for me, Battery meters was about 75% full when I took off. About a half mile later I noticed it had dropped to 40 percent. At that point I filled it up.

When I started it up, I noticed it was now in the purple range. It stayed that way until I got home (after stopping for coffee, too).

Total trip is only about 1.5 miles.

This has been a fairly typical scenario lately, but this was certainly more extreme.

So I think there is something wrong with the way the batteries are charged or the batteries themselves. Toyota disagrees .

Prius (2004-09) :: Irregular Behaviour Of The Car - System Malfunction

Problem and background: for PRIUS 2004 Gen 2 , 157000 km, not getting READY to drive.

1.Warning signals on Power ON, red triangle, yellow color engine, brake, ABS, skidding. Also the PARKING BRAKE RED signal (by the side of seat belt warning signal), does not disappear even if I release the foot brake.

2. Gear can move to N and parking P only, can't move to Drive D or Reverse R. No READY symbol,

3. I left the car in that location in open for a month, during heavy rain. But after coming back , the car had no issue and I was driving for 4 days before this issue started.

what I have tried:

1.Have removed the 12 Volt battery terminals and connected back, just to see if the errors disappear. No change. But did not check the battery voltage or suspect it . disconnected and connected the HV service plug.(orange color lever behind rear passenger seat).

2. Have been switching ON and off the car for 1 full day, First day the local Toyota service (non-prius), came to connect to OBD late evening, he switched on the interior lights and left doors open, within 10-15 minutes the lights started dimming. Before he could pull the information, all shutdown and 12V battery down. his measurement at battery without removing any terminal showed 3.6V.

3. The second day took the battery out and charged at local battery service guy for 6 hrs, he say's charged at 3A, the indicator showed green, that means fully charged, his measurement with no load 12V. After connecting to the car myself, checked the voltage at display by putting to diagnostic mode, showed 12 volts (only with display on) with headlight on and pressing brake drops to 11.6volt. IS THAT OK?

4. The third day got the new battery and replaced, showed the same voltage 12/11.6v, but I can't be 100% sure if that is a brand new battery, the box was open, and since the car didn't start, the battery sales person has taken back the new battery in the same box. I connected back the old battery, it was holding the same voltage. SHOULD I still SUSPECT BATTERY?

5. I can make the READY indication blink twice, if I press hard the brake pedal and hold the POWER button few seconds, during this time I can hear CLICKING NOISE behind at HV BATTERY SERVICE PLUG grip? does that say something?

Golf IV R32 :: Intermittent Wiper Speed Only Works On Low

The wiper-speed selector (aka: the little switch on the top of the right stalk) does not seem to influence the frequency in which the wiper activates on intermittent mode.

Lowest setting: 5 second interval
Highest setting: 5 second interval.

This is strange as it was working a week ago

Specifically any fuse for this function? Or is there a specific relay that takes care of this action?

Chevrolet - 1500 :: Intermittent Windshield Wiper Operation

I'm trying to figure out what could be the reason why I have Intermittent wiper operation on this truck. It's a 99 Chevy 1500 4.8 4X4. It's almost like the wipers have a mind of their own. Sometimes working properly but most often not operating when needed the most. Is this one of the set-ups that has a pc board with a bad/cold solder connection? I'm sure that one of the regulars here has come across this at some time or another and found it to be a simple fix.

Prius (Gen 2) :: Backwards Thumps When Car Was Parked

2005 Prius w/90,000 miles.

This morning I got in my Prius and started the car. I was waiting for my son and almost absentmindedly I put my foot on the gas enough to get the ICE revving up. The car was parked with a very slight incline forward (a few degrees at most). After a few seconds the car thumped backwards. It then continued to do that continuously with a thump about once a second. It's not a hard thump, but it's very noticeable.

It is almost as if a very small amount of power is being applied in reverse and then released quickly. I shut the car down and was able to replicate the issue. There are no error codes on my OBD2 and no unusual engine lights. Is it normal?

Prius (2010-12) :: ICE Warm Up When Moving Backwards

Ever since I got my 2010 Prius (about a week ago) I always get a little scare whenever I'm backing out of a parking place. The Prius seems to think that the ideal time to start the ICE to warm it up is when I'm moving backwards and halfway out of the spot... which, of course, causes a little vibration in the car and makes me think I hit or ran over something. It really scared me the first time... especially since I had only had the car a few hours then and I'm mostly used to it by now, but every now and then it catches me off guard.

2013 Toyota Avalon / Intermittent Wiper Blade Loud Click?

I have a 2013 Toyota Avalon Hybrid Touring Model.

The vehicle is great, however the clicking noise from the wiper relay is obnoxious. It is only when the intermittent wiper setting is applied that the noise is apparent. You can also duplicate it by manually moving the wiper knob up and down. I showed the dealer this twice, and both times they say it is normal. I will take a video later today and post it to show.

Kia - Sedona :: 2004 - Wiper Fluid Pump / Clock Working Intermittent

I have a 2004 Kia Sedona. The clock on the overhead console and the wiper fluid pump are both working only intermittently and they alternate working. In other words, when one works the other does not. My mechanic has checked it and has not found anything obvious.

Golf IV / Jetta IV :: Intermittent Windshield Wiper Stall Halfway Up / Move Really Slowly

At times my windshield wipers stall halfway up my windshield or move really slowly. Other times absolutely fine, I already checked both battery terminals and niether were the issue. What's the best way to get to the wiper motor to check the connections. Or does it sound like a ground strap issue elsewhere on the car.

Santa Fe (CM - 2007-12) :: Unnatural Electrical Behaviour / Lights Came On

I have a 2007 Santa Fe GLS 2.7L

I purchased this used over a year ago and have had a lot of good luck with is so far..

But yesterday, I opened my Front passenger door and closed it. Opened the rear driver's side door and closed it, lights came on.

I than got into the drivers seat and proceeded to start the car, I had NO POWER. Not even the little red security light was on.

I was at a loss, I got out of the car and opened the Rear door again and not lights, so I closed it.

Got back into the car and it started right up...

Prius (Gen 3) :: Noise Near Shifter Knob Occur Only At Freeway Speeds

I have a 2010 Prius no frills model with 5500 miles on it. I've started hearing a noise that sounds like loud burst of radio static. I hear it with the radio off or on. It's very intermittent, but seems to occur only at freeway speeds. Seems to be coming from underneath the shifter or underneath the dash in the same area.

Prius (Gen 2) :: Shift Knob Making Click Every Time On Selecting A Gear

This morning the Shift Knob made a click every time I selected a gear, for about an hour, then it went away.

It was colder than almost ever here (Berkeley, CA) last nite, 30F. But there was no click back in '05 at 10F (in Prudhoe Bay, AK).

Mechanics (even the dealership!) say not to worry--probably a plastic part--just advised me to shift gently.

Prius (2010-12) :: Radio Volume Control Knob Stops Responding

I have a 2010 Prius and I noticed for the first time today that the volume control knob stopped responding when I twisted it. I turned off the radio off then back on and it appeared to be working again.

My car has about 41,000 miles on it so I'm not sure if the warranty is still applicable.

Gen 2 Prius (Audio/Electronics) :: Volume Knob Didn't Work / Column Is Sheared Off

When I got my Prius, the volume knob didn't work, and I thought I could live with it. Steering wheel controls work fine except when I'm turning the wheel, then I have to chase the buttons. I really want the volume knob to function properly.

The post that inserts into the head unit volume receiving column is sheared off and stuck in there. I tried super-gluing it back together, but that didn't give me the slight bumpy sensation when I turned it. I thought it would at least depress, but not when it was superglued together. It won't pop in and out when I press on it when it was glued.

Gen 3 Prius (Audio/Electronics) :: Navi Screen Opens When Volume Knob Is Turned

I have a 2011 Prius Four with JBL/navi package. When I go to turn the volume knob up or down the navi screen pops open as if I were going to eject or insert a cd. Only sometimes will it close back up when I press the eject/close button otherwise I have to twist the volume knob back and fourth until it randomly closes. THEN, when I set FM/AM station presets, power off the car, power car back on, the screen shows "loading" and everything resets except for the Bluetooth phone settings. Is there any firmware update I need to install via usb?
