Prius (Gen 2) :: Sluggish / Jerking When Gas Pressed - Not Going Over 50 Mph
Nov 9, 2015
I have a 2005 Toyota Prius that was handed down to me from my grandma (1st owner ) . She had given me the car at 70k miles . Over the past two years I have managed to boost the miles up to 110k . My catylic converter has been giving me problems for the past year ( icon showing up on display screen ) . I just got it fixed . Damn thing costed me 1200$ . Shortly after, my car started acting sluggish . Not going over 50mph , jerking as I press the gas , and when I sat at a red light for too long I couldn't get my miles to go over 20mph .
I assumed that it was the 12v auxiliary battery so I had that changed . Another 300$ out the door . Seems to be running "normal" again but it still has that jerk to it and it takes FOREVER to reach up to 70 mpg. I posted a picture of the icon that has appeared before I had the catylic converter changed ... Still displayed on the screen till this day .

Ok, did an intake manifold cleaning on my 99 Accord the other day, and now I have problems...
Long story short, some time ago my car started to have a very rough idle. Took me awhile to find the problem. Turned out the air hose, between the filter and throttle body, had developed a big hole on the underside. So I replaced it and while I was at it used some throttle body cleaner, spraying into the intake manifold chamber. Lot of junk blew out the tailpipe. The car ran much better, but the idle could still be a little rough. I ran it that way for awhile, and finally the other day decided there was probably still some junk in there and it was time to really clean it out. So I took ff the throttle body and intake manifold housing. There was a lot of junk in there! The small intake on the passenger side was completely clogged shut. (I understand this isn't surprising on these cars.) I used a bunch of rags and 2 cans of Valvoline throttle body cleaner and a lot of elbow grease and cleaned it out. I was thinking to myself that whatever I didn't get with the rags flushed through OK, but I didn't want to take the whole intake manifold out.
So I put it all back together. (I took a video before I started, so I'm pretty sure it's all back together right.) But now I have problems. The car starts. It idles fine mostly, but can be a bit rough. But the trouble starts when I put the pedal down. If I do it in Park, well, if I push it quick the engine just dies. If I push it slow, the engine revs then quits, revs and quits, over and over. Similar if it's in gear. If I push it hard, the engine stalls. If I push it gentle, it revs up, but chugs along a bit.
I've run some seafoam through it, thinking it was clogged up with all that junk, and sure enough, lots of smoke comes out, but nothing is improving so far. What have I done wrong?

No matter how I press or hold them nothing changes on the display. Unfortunately nothing turns up for me on a google or PC search for this issue so that can't be good for an easy fix. I saw one thing about a bad switch but not details. I just bought this 2010 Prius with 52k miles yesterday.

This morning I pressed Start and all I got was the Red Triangle. This has happened a few times in the last month, but it always started up right after that. Today nothing. Well, a couple other attempts got some of the display to come up, but really nothing. The doors, including the trunk, won't unlock.
Since it has over 119K miles I think it might be the Aux battery, but it ain't easy to get to as I have to enter the trunk via the passenger compartment.

2006, 112k mi. there's been a whine-like noise that only happens when the accelerator is pressed ( and mostly noticed at highway speeds) and stops immediately when accelerator is released..

I have Toyota Prius 2006 with about 58k miles. For the last 12-16 months I encounter the following problem: when I press brakes, I hear knocking noise. It doesn't happen every time, but when it does it only happens when I press the brakes. Once I brought my car to a Toyota dealer and waited for an hour until my car was taken for a service. Mechanic found no noise. I tried to produce this noise but my car didn't want to cooperate. I don't see any messages on a display screen. It happens with power on/off and pressed brakes. What the knock is and how to get rid of it?

Don't get me wrong this car wasn't a speed demon anyways, but now it seems like it takes a little more throttle to get going. It could be bad gas or something, I'm not sure. Ive only had it 2 months. Would it hurt to put a fuel treatment through it? Slight sluggish feel then what you were use to when you bought it? 2800 Miles on my C2...

I have an 05 prius with 108k miles that I bought about 3 months ago. I had noticed some times during phase 1 warm up where prius is in park and ice is charging the battery there will be mildly violent jerking of the car.
I was messing around the other morning, after driving the car about 30 minutes then letting it sit for about an hour in 40 degree f weather. I readied the car and it started charging the battery. While still in park i pressed the gas pedal to see what would happen. The mfd showed no arrows which I assume is normal. But when I let off the gas pedal there was a abrupt jerking as the mfd showed power flowing from the ice to the battery again.
Experienced jerkiness while in phase 1? After phase 1 is complete I do not notice any more of this behavior.

My car has around 160k miles on it and for the past 30k miles (give or take) I have had a jerking sensation when the car switches from gas to electric. It is a stronger jerk at low speeds and more like a shimmy at 40-50 mph. It has progressively gotten worse with time, I mean it's by all means drivable but I have been trying to figure out what could be wrong before it has to be replaced and I'm on the side of the road.

I was wondering if this problem is the "Barking" noise that keeps coming up the search or is it another problem. I will include a link to the video down below.
To start off, the Prius is 2010 Prius II and has 120k miles on it. Great Car. Only other problem was AC compressor dying at 90k.
The chirping noise happens when the brake pedal is pressed and does not go away until the release the pedal. It makes the noise regardless of whether the car is on or off.
It makes the noise when the car is stopped and or when the mechanical brake engage at between 0 and 6 mph.
Noise does not occur when the brake switch is removed. Not valid solution since the brake lights will stay on. It does not affect the performance of braking.
Here is the link to the video .... .... ....

I have both a 2010 Prius and a new v and have just noticed that if you press the 'Econ' button once, the little light goes on in the dashboard. If you press it again, the little light goes off. The same occurs with the 'pwr' button.

Today I faced another problem i just try to start my car but, due the dead 12v battery it didn't start so i pressed the BRAKE PEDAL until it reach the bottom, again i tried to press but its not going to the bottom why was that, is it due to dead battery? And last time i called an automobile expertise to jump start my car. They check the voltage with a digital multi-meter and he said me if you jump start even you will get this problem again until u replace the new battery. but i said him it doesn't matter do a jump start and finally it was ok . Now again I faced the same problem and this time i am going to change the battery.

Lately I have found that when I am trying to go up an incline on my road, that my car has trouble accelerating. Almost as if the engine is being choked off like it is about to stall or is out of gas. I have to press the accelerator almost to the floor to get up the incline. The suddenly it will lurch and accelerate rapidly as if I have put the car in Power Mode.
I should also add that this only happens when the engine is cold. I didn't have this problem last year at all. I usually wait a couple of minutes after the engine starts before I try to drive, but that doesn't seem to work.

I've bought a brand new 2012 Prius C 3.
This morning I was trying to back out of a parking spot and put it on a reverse after starting my car. As soon as I my car started moving forward and hit the curb right in front of the car. I couldn't believe my eyes so I put the gear back to Parking and back to reverse, and as soon as I touched gas, it again accelerated forward.

I recently picked up an 05 that now has about 101k miles on it. When coming to a stop if I put my foot on the brake and hold a steady pressure the car increases the braking pressure drastically once it's under 10 mph and the car jerks you forward unless you let off of the brake. I know its because its going from using the regen to using 100% disc pressure so what can I do to fix it?

While pressing the brake, the green light never comes on. The car is less than two weeks old and this is happening.

I've noticed that when I'm stopped, or in park, and I push on the brake pedal hard I hear a squeak or chirp that sounds like it's coming from the wheels. It might even sound like someone is honking at you as if you were not going when the light turned green. I have not been outside the car when this occurs, so I don't know exactly where the sound is coming from.

I purchased a 2001 Prius with 123K miles about two weeks ago. I knew the HV battery was shot when i purchased it. I decided to see if I could rebuild the HV battery on my own.
I'm very mechanical but not the brightest bulb in the room when it comes to batteries and anything electrical.
So here is where I'm at so far:
- I removed the HV battery.
- safely rested it on 2 horses (I used horses because it would give me easy access to the bottom to remove the bottom screws)
- Removed all 38 modules from the battery pack
- cleaned the busses in vinegar
- inspected each wire that connects between buss and the nut.
- tested each battery ( one of the batteries tested at -0.1, the others tested at 6.8)
- I don't know how to load test the modules, so I couldn't tell if they would drop dramatically under load, so I ordered 38 used replacement batteries off of Ebay. (Gen II)
- these replacement modules were about a half inch longer than my original modules.
- The replacement modules arrived. I cleaned the terminals, tested each one and installed them.
- Connected the battery back into the prius.
- Installed new 12V battery from the Toyota dealer.
- The Prius started right up.
- Drove it around for the first time for about 10 minutes.
- When i was driving it, the monitor in the Prius would show the engine running most of the time but sometimes it would show it charging the HV and other times charging the 12V. the engine would shut off at stop lights and resume when I pressed on the gas pedal.
- while driving back into my driveway, all of the warning lights came on and the battery fan kicked into high gear,
- I can't remember the code I pulled but it was in reference to the cells being out of balance I think. I'll have to check it again tonight when I get home.
- I removed the HV and tightened the nuts around the busses hoping the issue would be resolved.
- I was able to drive it only a few minutes before the issue returned.
other issues I noticed.
While waiting for the replacement batteries to arrive, I did the following:
- changed the cabin filter
- did an oil change.
- changed the tranny fluid and removed the tranny pan to clean out the slime and clean off the magnet.)
- changed the rear brake shoes.
- changed the front brake rotors and pads. ( they were in awful condition due to sitting so long)
***when I pressed on the brakes, only the rear brakes seem to engage, not the front. I never attempted to bleed them because I know only the dealer can do that)
