Prius (2010-12) :: Dies When Accelerating - Fixing P0A94
Jun 26, 2014
I'm a longtime reader & today I got a excellent reason to make a post - I was at ~20mph & had just went around a corner & tried to accelerate fairly briskly & the car just dies. Hybrid Failure iirc. I got out of traffic & pulled the codes (BT dongle already installed) Torque shows P0A94 Powertrain. I reset the code & power cycled the car but nothing changed. The traction battery still was showing 5-bars so I moved the vehicle <.1 mile to a safe location. Battery was still at 2-bars when I powered it down.

Just posting another 'Check Hybrid System' thread. 2011 Prius with 68k miles on it. Had not had the E0E recall done before. Turned the corner out of the supermarket on Friday, and the car lost all power. Coasted to a spot on the side of the road and all the lights lit up and 'Check Hybrid System' came on. Prius would not restart at all. Car is driven approximately 80 miles a day, mostly flat land, weekends usually spent in mountains. Had it towed to the dealer, they pulled P0A94 and P324E. Didn't replace the whole inverter, but looks like the repair kit, including 04899-47021 Transistor Kit replaced. Got the car back and seems to working as before. Will check mpg over the next couple of fill-ups and update if anything seems different.

My new-to-me (bought in May this year) 2010 Prius last night suffered. Nearing home on my usual 21-mi commute from work and on a secondary road, I was stopped at a red light. As I normally do when at a red light when a rather spirited start isn't needed (no or few cars behind me, not uphill, etc) I pushed the "EV" button to take advantage of electric acceleration up to 25 mph. All seemed normal as the light turned green and I started off. I don't know if I reached 25 or not - must've been close - when all of a sudden the acceleration stopped as if I'd taken my foot off the pedal when indeed I'd not. Simultaneously, a circus of lights lit up on the dash along with the fairly ominous message of "Check Hybrid System."
As with all things electronic these days, I figured a good ol' fashioned reboot was in order. Turned it off and back on and...same thing of course. Being near an intersection and a very bad place to be stopped - and not knowing if the car would actually move - I pressed the accelerator anyway, despite the warning lights, and indeed the car started to move. It seemed to cap the speed at 12-13 mph, which immediately seemed like some kind of self-protective safe mode. Luckily, I was within spitting distance from home, so I limped the last 1/4 mile in this state - and at 12 mph.
There are probably 5-6 warning lights on in addition to the big "Check Hybrid System" message. Let's see, first and foremost, the yellow triangle of death, followed by what I think is the Slip indicator (car icon with wavy lines), the CEL, the encircled exclamation point which I think is the braking system, and I forget, a couple of more. I should've snapped a pic but I was in a hurry to troubleshoot.
So I used my Actron scanner to pull the P0A94 code. I didn't see that it's able to read the sub codes, or maybe that's a capability that only the expensive dealer scanners have. Anyway, I can't conclude what it is other than the generic "DC-DC Converter Performance". I know that here and elsewhere there's a list of all DTC codes, and I saw that this code has 17 sub-codes, many of which are related somehow to the inverter, which seems to have been the subject of a recall in Gen II models (acutally the inverter cooling pump IIRC) but not on Gen III.

The car is a Prius 2 2012 about 3.5 years old 48000 miles on it so far nothing ... I did the recall realted to the inverter while back.

I just brought home a brand new 2011 Prius base model (it was the dealership's last one...their showroom model...=D)!
Unfortunately, I forgot that the hatchback door opens up REAL high and the spoiler kissed my garage door. Now there is this white mark and I was wondering if I can fix it at home? What is the difficulty level? I'm not really a handy-man so don't want to try to fix it and end up making it looking even worse (unless it's super easy to do).
The mark is not too too noticeable...it's about the size of a pencil tip. It just happens to be white so stands out slightly against the black.
Also, most important, will this small blemish get worse over time and cause the mark to get larger over time (I'm thinking of how a crack can propagate and eventually cause a failure...except this won't be as serious)?

I picked up my Prius III last month (love it) and noticed some hairline scratches in the black spoiler, but thought they might wax out as they are pretty faint (they didn't).
Looks like the dealer ran a gritty wash mitt or sponge over the spoiler and swirled the finish. In the bright sun you can see many light scratches in the finish.
I thought about using a gentle polish, but wasn't sure if that was a good move as I think it is just a high gloss plastic and not paint. The last thing I want to do is add more damage.
I did wash, clay, and wax my car as soon as I could and spent some time detailing it and thought the scratches were reduced, but had it out today and they are still there.

2012 v five with 56,500 miles. Getting onto an on ramp and accelerating when car jolted and dramatic power loss. I posted a thread about my car "ticking" as I slowed down from 30mph and I am wondering if this was related. I had no choice but to drive it home and kept car under 45 mostly on side streets. Car is not assisted at all by electric motor and can barely go up hills. With windows open and attention to any unusual sound i noticed no more ticking when slowing down from 25 to zero.... I think its covered under warranty at least powertrain, hopefully. I know a few of you here have the ticking problem to so i will update if this is related after i bring it in for service.

Not like when you leave the dome light on overnight. I mean when the 12v battery has reached the end of it's useful life after 5-6yrs. How do you know it's time? What will my Prius actually DO? I ask because,in this -10 weather we've been having, my truck wouldn't start. It did that "old, dead battery thing" we're all familiar with. Got me to wondering about how my Prius will act.

I picked up a 2002 Prius with 164k, still on original battery. It giving code P3030 which evidently relates to a high voltage line snapped on the bus bar.

Any diagram for replacing a side mirror? I've read the threads about how to replace them, but if there was a cutaway view or diagram, it would sure make my job easier. I have a 2007 Prius, a replacement mirror, and the desire to fix it myself. I just do much better if I can visual the job at hand.

I bought a used Certified Prius with 49k miles on it. I noticed when accelerating (and the display shows that I am using the ICE but not so much that it shoots up into the "Power" portion on the far right) that the there is a clicking noise coming from the front passenger side of the car.
It sounds very much like this:
I don't hear it when only the electric motor is running, and I don't hear it when I really punch it and the power meter is completely filled up. Its more when the power meter is in the middle of the display and the ICE kicks in and I am slowly accelerating.

My 2010 Prius has been making an odd noise intermittently while accelerating. I haven't been able to reproduce it for the mechanics (of course). The best description I have for the noise is this. It sounds like the click/rattle sound a car makes when it is stalling. Just sped up. This can happen at any time I accelerate (even at highway speeds) but it usually happens just after I start moving from a stop. When it occurs it feels like there is a drop in engine power and I either have to take my foot off the accelerator, or push down harder and power through.

So lately I've been hearing what sounds like a slight lifter knock that develops at 1500 rpm to 2700 (I have ultragauge) when accelerating or maintain speed, and it only appears when the engine is at operating temp and disappears when rpm is below 1500 rpm and above 2500 rpm my oil is running at 3900 miles using Toyota synt 0W-20 and it looks pretty clean and at high mark of the dip stick.

Just bought a 2010 Prius with 48k miles. I'm noticing what feels like a slight slipping when rapidly accelerating, or that's what I would call it in any other car. It's barely noticeable, and my only concern is if this is the beginning of a transmission issue.

I have noticed in certain circumstances that the engine seems to be in a resonance where it is shaking noticeably and getting worse not better. It happens in two situations.
One is after gliding and slowing to make a turn (with the engine off). As I am exiting the turn and hit the gas the car shakes a lot for about a second or two, then smooths out.

I've noticed that when accelerating from a stop and turning onto an adjacent street to the left or right, there seems to be stuttering or shaking coming from the engine. I'm usually in ECO and only 1/3 of the way into the "engine half" zone on the HSI. It's not consistent but has become a bit of an annoyance.

I have read that when accelerating from a full stop, it is better to accelerate briskly, but keeping the bar graph in the ECO zone, to cruising speed is better overall for gas mileage compared to accelerating slower and taking more time to reach cruising speed....
I have also heard that it is better to accelerate using the bar graph and making sure it only goes half an inch past the ECO display above it. This way uses less RPM.
