Prius (2004-09) :: 2006 - Jumpy Transmission When Car Switches From Electric To Gas Engine
Apr 9, 2014
I bought my 2006 Prius used and I had just put it over 100,000 miles. The dearlership has replaced the HV battery under warranty and suggest that I replace a slightly leaking waterpump and cracked belt, said nothing about the transmission.
My concern is, my transmission. When the car switches from electric to the gas engine, the car jumps a little bit, and it's an obvious and not smooth shift. And when I put it in Park, the vehicle rocks back and forth a bit, shifting a few inches before coming to a still position. Is this standard with other 2006 Prius? I drove my friends 2007 Prius and the shift seems smooth and it doesnt rock when you put it in park. Should I be concerned and if so what should I do?

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.

Notice roughness/jumpiness in the transmission when slowing to a stop, or crawling along (like in a shopping center)? it's quite evident on my car, and perhaps i just have a problem that nobody else feels.
It's as if the tranny is downshifting when slowing to a stop, and I can really feel it...makes it difficult to come to a smooth stop. and then if I'm moving very very slowly in heavy traffic, it seems to be "wandering" between 1st & 2nd...something like that...and it's very jumpy. Not smooth at all.
I realize that Lexus may come up with some reprogramming for trannies (that happened on my '01 GS, and it made a big difference).

I've a 2004 Prius. Had it for 3 years. 40,000 miles. No problems what-so-ever. 55 to 60mpg without any effort.
During the winter I noticed that when the petrol engine switched off - there was a jolt. (It used to be totally imperceptible.) Nothing drastic - I have to be on smooth tarmac to notice.
My Toyota dealer said this sometimes happens in cold weather. However, the weather has warmed up - and I can still feel the jolt.
Don't know if it's connected, by the central display diagnostic check tells me...
EMV. Code: 01-DC. Sub-code: 1C6-F6-1

Its a 2005 model with 45000 miles on the clock, so low mileage for the year. The problem with it is the engine starts up ready fr a journey, and as soon as the accelerator pedal is pressed, the engine cuts out.

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.

When I accelerate from a stop, the car jumps, slows down, jumps again, etc... I do hear a noise when I accelerate rapidly on the highway, almost like a leak somewhere, but I'm not really sure.

More lately I've been noticing that when moving slowly, if going over a bump in the road of any sort, the steering wheel seems loose and the car wants to jump to one side or another slightly.
Picture moving straight ahead, and hit a rough section of or a small pot hole, and the steering wheel will move by itself to the left or the right quite a bit. I haven't noticed anything on the highway.
What can cause that? How should I go about describing to the service advisor so that it doesn't seem trivial? Last thing I want is a steering rack or major front suspension component slowly dying right after my warranty runs out. All I know is that it has struck me as "hey this doesn't feel normal".
Am I just being overly sensitive now that my powertrain warranty has months left on the clock, or does this sound like a legitimate concern? The last few things I've had them look into at the dealership during other service visits have been returned to me as "no problem founds" and I'm starting to feel like I'm just going crazy.
After some additional googling, it seems like I'm describing something commonly called "bump steer"... how much bump steer is normal for this car with stock suspension, I don't know... all I know is that I seem to have become acutely attuned to it whereas I never noticed it before. Hopefully I don't get the "we didn't notice anything wrong" again if I mention it, and whatever it is, is covered.

We've owned our 07 since purchased new in 06. It's always made this noise, but it used to be for a short period of time (1-2 min). Now it goes on and on for 5-10 min. It sounds like it's getting "stuck" and starting the cycle over.

My 2006 has a smart key. Today I pushed the button and the lights came on but it didn't start. I got a message in the screen that said something like "the transmission "P" function is not working. Park the car on a flat surface and engage the parking brake" It was parked on a flat surface and the brake was engaged. The car would not turn off. I held the button in and eventually it powered down. I started it again and it would not go into gear. I put the key in the ignition, turned it off and got out of the car and shut the door, it wouldnot turn off and the display (even for the transmission) was not completely lit so the letters weren't formed. We finally got it turned off and then back on and were able to get it in gear and take it to the dealership. They can't figure out what is wrong. Their next step is to diagonse the problem by removing the dashboard and back seat at a cost of $950. If it's a wiring problem it won't cost more than the $950 but if a computer needs to be replaced there will be an additional charge.
I have read lots of posts here but no one mentioned having the dash and rear seat removed to diagnose the problem. The car has 81,000 miles and has not had the 12V battery replaced. I do not believe the dealership is crooked, I believe they don't really know what else to do.

My Prius C II is at a little over 6,000 miles. I've noticed when I'm accelerating from a stop using the electric engine, that at around 11-15mph I hear a clicking noise coming from the left hand (driver) side of the vehicle.
To hear the sound my windows have to be down and my stereo not playing.
Is this clicking sound while accelerating normal? I know there's a clicking sound that happens when I start my car and when my car sits after parking for a second but this clicking noise sounds like its coming from the front left hand side... not inside the cabin.

I'm confused about my PIP. Every night, I charge my battery fully and have 11-12 miles of charge to consume during the day. However, I've noticed that at least 10-25% of the time I'm driving in EV mode, the EV indicator goes off and my gas engine just runs. It's not because I'm driving the car hard - it even does it when stopped at a light.
My only guess is that either Toyota wants the gas engine to run once in a while or else it's trying to charge the Hybrid battery (even though I'm not using it at that time). It's a really bummer because even though I'm rarely out of EV mode, I'm burning what seems like a fair bit of gas - after 300 miles of mostly EV, I'm down to half a tank of gas?

I am having a problem which I can't pin down what it is. When I am driving my 2001 Prius, only after a turn, it seems to get real jumpy and the check engine light will come on during this. I know this is when it comes on because I unplug the starter battery to reset it several times. I've had it put on a computer and it gave a long list of things it could be up to and including replacing the entire gas tank assembly.
I've changed out the gas cap which was one of the things on the list, and I have a charcoal canister I got from the junkyard, but it's a pain to change, so if I don't have to change it, I really would like to not have to if it could be something else. I also put the highest grade of gas in it.

My girlfriend just picked up a 2007 Prius Touring, 78,000 miles, original owner. It was a private sale and I took a look at it for her. I'm just learning about the Prius and stuff to look for, but everything looked good on it to me. After purchasing it she noticed a noise coming from the drivers side dash. I searched here and saw that dash rattles are common, but this sounds more like an electric buzzing/whirring noise. The duration of the noise is always about 2 to 3 seconds in length, then it stops. There doesn't seem to be any common factor for when it occurs. Is there anything electric on the drives side dash (far left side, closest to the window), that might be making this noise? It's not super loud, you can't hear it if the radio is on.

2006 STX 4.6 .... I recently changed my oil a couple of weeks back. I've noticed spots of oil on the driveway. I thought it may be coming from the oil pan drain plug but i checked it and it seems to be coming from where the transmission connects to the engine. Lotta oil on the bell housing. That's where it looks like it's dripping off of. Could it be the rear main seal?

When driving, when I hit a medium- light bump in the road and slightly jar the car, I hear a beep and the car goes into EV mode. This means the rpm's drop to zero, the gas engine shuts off and the car goes electric only. This is a problem because the state of charge then runs the bars on the multi-function-display down to the purple bar level.

I have a 2009 Prius with about 56K miles on it that I absolutely love. Now I know from reading in the forums an my own experience that when the A/C compressor starts running you hear an electric whirring sound. My question is... is it a cause for concern when the sound it makes seems different -- the pitch sounds lower to me now. The A/C still works fine, but I didn't know if this changing sound means the compressor was on the way out.

After a long day at work, I stepped out of my '06 Prius and was greeted by an obviously struggling CHRS pump. It sounded like it was having a hard time maintaining speed, and to my ears was screaming; better replace soon...

It's been like that for a a while now. Every morning the hybrid battery would run down to last bar. When I start the car it would be 3/4 full and it would keep draining even though I'm on flat road.
The overall mileage has not changed much but its annoying with the battery goes to last bar and there's no electric power to accelerate.
