Prius (2004-09) :: Red Triangle / CEL On And Lost Power While Driving

I have 2005 Prius with 110k. Yesterday, red triangle and check engine light came on and I lost power while driving...SCARY. Took it by dealership. They called this am and said it needed a new HV-ECU and that would cost $800. The error codes they gave me were P0A78 and P0A94. Anything else I should ask them to look at? I'm wondering if the HV ECU is something I could buy used and install myself? I'm not a mechanic but am comfortable with most DIY projects.

Touareg :: Lost Power Suddenly While Driving V8 2004

While I was driving my car suddenly was losing power.I tried to hit the "gas" pedal harder and it didn't react.It stayed on the same gear and after 2-3 seconds it was ok. After 10 minutes it happened again but this time I couldn't do anything. I thought it was the transmission problem so I went into manual mode to shift it down. It didn't work at all - I was shifting down but didn't have power so I had to stop. I stopped put in P turn engine on and everything came back to normal.It's worth mentioning that one time time I had to pull over and I didn't turn the car off. After couple minutes the car started to vibrate and died. I turned on and everything was ok. Fuel filter or is it something else?

Prius (2010-12) :: Suddenly Car Lost Its Power While Driving At 35 - 40 MPH

Up until this morning I thought I had almost a perfect car with a potential of lasting for 10 years but this morning, while I was driving on a local road with 35-40mph, so suddenly my car stopped moving and I couldn't even pull over as it completely stopped with no error or any warning/alerts! So, I turned it off and on again, it started working but I was still nervous if it would happen to me again while driving on a freeway but it didn't and I have made to work safely.

Now a question is should I bring it to the dealer today and have them run their diagnostics on their computer to see if anything is wrong with the car engine/ battery/ or anything else or should I just reboot it like we do for computers and go on everytime it happens? It's just little scary to think of its happening during a busy highway driving! I have driven it since July and has about 14K and I have had a good MPG of anywhere between 50 to 60.

Prius (2004-09) :: Red Triangle Came On Dash And Lost All Driving Functions

I was at an intersection and red triangle came on dash and lost all driving functions. Had to turn power off, then turn back on. Was able to drive 100 yards to a parking spot, but it went out again. Reset car again, then it happened 4 more times within 2 miles while driving. Had to call tow truck. Just kept shutting itself down. How to fix this. See picture below for the message I got when it happened. This is the first time my car has malfunctioned like this. I think maybe its throwing itself into park or neutral (judging by the P-lock message below) and cuts all throttle control to car. Has 105,000 miles on it.

Prius (2004-09) :: Car Lost Power, All Sorts Of Warning Lights Came On

My Prius is 07 with 146k in southern California, for two days every morning I took a short trip to a store then when driving back home the prius battery lost bars fast and I lost power with all sorts of warning lights. Then I drive off with no problems for the entire day. I disconnected the aux battery and that reset the Error codes, I checked the inverter pump and works properly, I checked the aux battery and shows 12v when off and 13.9v -14v when on. This happens every morning so I suspect it's the aux battery. 3months ago my dash lights went out and rebooted the car with no problems.

Prius (2004-09) :: Warning Lights Came On, Lost Engine Power

199k on my prius. I'm driving 65 mph and bam! All warning lights come on, PROBLEM, comes up on the mfd, and the mfd had a funky little broken cat symbol light in the top left corner.

I lose engine power and coast to a stop. As I'm coasting the speed display stops showing my speed... even though the rest of the gouges are lit on the display. While parked I realize I have very little 12v battery juice....

With a jumper pack on the front terminals I get the cat home. I ser on the display the my hv battery is stuck at one bar.

At home I charge the 12v battery and get the hv battery fully charged by holding the gas down in drive with foot on the brake. My Toyota mechanic told me to do that. All warning lights go away. I leave a jumper pack on the battery in the rear and take for another test drive. Car is better but still sluggish... Try to get it up to 50 mph and bam! again all warning lights return.

So I get the car to toyota dealer and and my guy reads the codes and tells me every ecu is showing codes abs recommends 12v battery replacement. He clears the codes. So I buy a brand new battery and after installing it all warning lights return on test ride. Car won't do over 50 mph and is def still a mess.....

Prius (2004-09) :: Engine Straining / Lost Power And Poor MPG

Basically, about 3 weeks ago I noticed some problems with my 04 Prius. It has 72k miles on the clock. The exhaust was making a farting sound. I have since diagnosed this as a hole in the back box which I promptly replaced. But the real problem is the power.

When driving in electric mode, the car runs as normal. But when I press down on the gas just a little more to the point where the ICE kicks in, it doesn't give as much power as it used to. For example, in electric mode, cruising at 30mph and achieving 99.9mpg, I'd press the pedal down about half an inch. Where this used to kick the ICE in and show 60mpg+ (with the engine charging the battery and providing power to the wheels), it now shows about 30mpg. When I press the pedal a further half inch, it would normally show 35-45mpg, but now reads 16-25mpg. And when its fully depressed, it used to show 12-16mpg but now barely hits double figures and averages about 6.7mpg. Even on highways when I've achieved 60mph and gently ease off the pedal to maintain speed or really slowly increase, I used to achieve 60-70mpg but now I'd be lucky if it makes it to 40.

I also noticed that it produces considerably less pulling power than it used to. Almost as if the engine is really struggling, even when gently pressing the pedal and accelerating from 30mph upwards. This is having a large effect on my overall fuel consumption. I get so scared that I'm wasting too much fuel that I drive really conservatively now.

Prius (2004-09) :: Suddenly The Car Lost Power Entirely - Slips Into Neutral?

I have a 2008 Prius with about 95,000 miles. It is bloody cold here. About 4 degrees F when I got up. On the way to work, on the parkway, suddenly the car lost power entirely. Just started to slow down. No reaction when I pressed on the gas pedal. I didn't notice any warning lights. I flipped the gear shift to Drive, and the car accelerated again. About five minutes later, this repeated. For the rest of the trip it was fine, and there were no problems coming home. (Temperatures were still way below freezing in the afternoon when I left work though the car had been sitting in the sun. I don't know if this could be cold-related, but it's never happened before and it hasn't been this cold here for days on end before._

Prius (2004-09) :: Brakes Fail To Engage When Put Car Into Gear

I have taken my 2004 Pruis into the Toyota dealership and have been told that there is nothing wrong with my car and it is safe to drive. Here is what is happening.

Sometimes when I start my car and put the car into gear, which you are not supposed to be able to do without your foot on the brake, the car will start rolling before I take my foot off of the brake. I am on level ground when this happens, and I am positive I have my foot firmly on the brake. My first inclination is to push harder on the brake, which does nothing. If I take my foot off of the brake and then reapply it, then the brakes will work and the car will stop.

After this happened a few times, I started paying more careful attention. Whenever this happens, the ABS light is on. When I take my foot off of the brake, the ABS light goes off, and as I said, the brakes work normally.

Furthermore, this only happens if I have been sitting in my parked car for a few minutes with the engine off. It does not happen if I am getting into the car after being away for a few minutes, it only happens if I sit in the car for a few minutes and then turn the car back on to go somewhere.

This is, of course, not only irritating, but unsafe. It can be easy, if you are distracted, to have the car roll into someone or something if you are looking away, thinking that even though you put the car into gear, it will not go anywhere because it is not supposed to go anywhere, you have your foot on the brake!!!!

Prius (2004-09) :: Panel Alarm Lights Go On And Power Lost - Inverter Failure?

My 2008 Prius (111,000 miles) had all the panel alarm lights go on and lost power while I was driving on the freeway. After turning off the vehicle and letting it “rest” for 10 minutes, it restarted with only the red triangle alert light remaining on and was able to drive to my dealer service (about 40 miles) with no incident. The diagnostic code indicates that the inverter has failed, but the technicians are not able to confirm that this is the problem, since the system is now running. I was able to drive it home with no problems or warning lights. As this is a $4,000 part, I would like to know if this is a likely, or even possible, scenario for an inverter failing, or could it be another problem? Note: 3 months ago the auxiliary battery was replaced following the same circumstances.
