Prius (Gen 2) :: Engine Revving Up / Warning Lights Came On And Loss Of Power
May 13, 2015
I'm driving to work this morning and a bunch of warning lights came on. I was going uphill and the car wouldnt accelerate, the engine was revving up and my presses on the gas pedal didnt seem to be doing anything. I had to pull over a couple of times after shutting the car off and letting it cool down. Each time the car would eventually display the loss of power (would not accelerate, and engine seemed to be revving high with no input felt from gas pedal). Shutting off car and turning back on would cause this to go away.

I have a 2009 Prius with about 72k miles on it. Today, after about 45 minutes of highway driving, these lights all came on: master warning, the "check" indicator, VSC, the circle brake indicator, and the hybrid system warning on the multifunctional display.

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.....

My 2009 Prius was parked for two weeks. When I started yesterday the red triangular warning light, circular yellow light with exclamation symbol in center, and vsc warning lights did not go off. No previous problem with these. Top half of display screen blank. Vehicle started/ran normally. No change in handling or braking. On highway, cruise control would not activate.

I have a 2001 prius jap import. On a trip it beeped and up came the triangle, check engine light and car with !. The car lost all power and the engine stalled when I pulled over. I plugged in my obd2 scanner and no codes except 3000. Took it to our local toyota dealer who confirmed that code. Had the battery swapped out and still it does the same except now no codes. The car has below normal pickup speed and I can hear the engine rev a little but it does not seem to make any difference. Seems all the power comes from the battery. It will stall when all the error lights come on.

During a highway trip three months ago, my 2004 Prius suddenly lost engine power, the red triangle Master Warning light came on accompanied by a warning sound, and then the Hybrid System Warning sign appeared on the Multifunction Display. I pulled off to the side of the road and stopped. I turned the car off and then tried turning it on again. Engine power was restored although the warning lights remained. We took a chance and carried on with our trip. The same sequence of events reoccurred about 10 times on our 1,300 km journey. I took the car to a Toyota dealer where they found a C2318 DTC. They checked the battery and the HEV fuse but could not locate the problem.
We returned home and on the way the same thing happened a few more times. My service manual noted that the description for C2318 is Low Voltage Error (Power Supply Malfunction) and the trouble areas are HEV fuse, IGCT relay, Wire harness or connector, or Auxiliary battery. Since the car was nearly 7 years old I thought I had nothing to lose by replacing the battery, which I did. However, on a short 150 km trip last week the problem appeared again, once while approaching our destination and once when we were almost home. There seems to be a pattern in that the problem appears every 150 km or so of highway driving. It has never done it while driving in the city.

My ranger sounds like it's revving up real high when I take off but don't have much power. Know what this could be?

My 07 Prius recently started to get a traction control warning and loss of power on smooth, dry roads at 65mph on an interstate highway..... There was enough space between us and the 80,000 lb truck behind us..... As we slowed the warning abated and power was restored. BUT, the car will not maintain 65 mph without this recurring. Toyota has not been useful. Nothing stored on the pcu indicates what may have occurred.

I bought my 2010 Prius IV Solar/Nav pkg in Febrary 2011. I've got just over 10k on the odometer. Aside from the persistent rattle/clatter/clank noise over bumps that these cars seem to be famous for, I've had no issues. That is, until last Thursday. The temps here in Indiana have dropped substantially so I was driving in town with the windows down, sunroof open. About two miles after leaving the office, I turned a corner and the car suddenly seemed like it went from running on 4cyl to running on 2 cyl. No warning lights came up on the dash, but the car was definitely shuddering/struggling to pick up speed, and was obviously running very rough. It felt worse when I was accelerating, but I think it may have even been doing it when I let off the accelerator.
This continued for approximately two or three blocks until I parked the car & powered down. After debating what to do (call a tow truck, confer with SafetyConnect, etc.) I decided to try & move the car again. Of course, it was as if nothing had happened. No warning lights were on & the car seemed to be performing normally. Since then, I've had no issues.

This afternoon my 2007 made a long beep, popped up the red brake, traction control, ! triangle, ABS, VSC and check engine lights. It followed up by the gas engine cutting out and we had to coast to a shady spot (over 112 degrees at the time). After we pushed it into a parking spot we tried to turn the car on and off and it wouldn't allow us to change it to drive or reverse.

Bought a new Prius in 2005. In April 2010 (157,000km / 98000m) the triangle and engine icons warning lights came on. After about two weeks in the workshop, I was informed that the main battery went. Two months later (161,000km) the same warning lights came on again. Toyota agents informed me that now it is the water pump not circulating water through the engine. Toyota on its website states that the batteries should last the entire life of the vehicle. Is it possible that battery problem was wrongly diagnosed, and, that in fact, it was the water pump giving the problem in the first place?

2006 Gen II Prius with 105k miles. Last Thursday while driving, all the warning lights came on. Saturday we replaced the main battery pack in the back. The 12V battery seemed OK at the time and the car ran a few days successfully.

I was driving last night and my car Triangle Warning Light and Check Engine Light Went on along with on the nav screen a car with a ! mark in it came on. On The info screen the battery level was changing fast from fully charged to just about empty. The car lost almost all power going about 42 miles an hour. I was able to pull to the side and i waited 10 minutes then tried to turn the car on again. I was able to drive home and the warning lights were still on but at least my car had power. What could possible be wrong?

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.

Driving home early from work today, moments after leaving the parking lot the VSC warning light illuminated. Followed by ABS and Power steering lights a few seconds later.
Car drove normally. Systems seemed healthy.
I quickly pulled over, took this picture, and then power cycled the car. The warning lights turned [off] and stayed off for remainder of drive home (~30 min).

I was driving my 2006 Prius on the highway (120,000 miles on it). I'd been driving about 10 minutes and all of a sudden, the dash warning lights lit up.
Red triangle with exclamation point.
Yellow circle with exclamation point.
Yello check engine.
The car did NOT lose power. It kept driving fine with no noticeable change in how it operated. Fuel consumption stayed the same. Braking worked fine. I had a completely full tank of gas (had just filled it up before I got on the highway). Temperature outside about around 60 degrees.
I kept driving to my destination (another 20 miles at highway speeds). The car sat parked for about 3 hours. I returned to the car, started it up. The same warning lights appeared, except for the Yellow circle with exclamation point. Plus, this time I noticed on the energy monitor screen the graphic of the red car with the exclamation point.
Again though, everything seemed to be working fine. While the car had been parked for 3 hours I did some browsing through the owner's manual and saw a notation that is the warning lights were only yellow and not red that it was okay to proceed with caution to the nearest dealer.

As far as the owner can tell, the car is running fine. He hasn't driven it aside from getting home after the light came on. It seems to give a very informative error message. What it's saying?

This has happened to me twice now, 2 weeks between occurrences:
Driving to work, about 10 minutes into the trip - traction control light comes on, "Reduced engine power" message appears on DIC, and check engine light comes on.
The car is an '08 Prix, no charger, with 51K on it. This is actually the first trouble I've had with the car since it left the dealer lot.
I pull over, turn car off. Turn back on - traction light goes out, and engine is running at full power. The check engine light remains on for about 5 starts/stops then goes away.
I haven't had the engine scanned yet. The only thread here I could find recommended replacing the throttle body. The person decided to clean the throttle body, and that was the last post.
I was thinking of removing the individual electronic components from the TB and cleaning them and the area around them in the TB. (I have the sensor-safe cleaner for TB's).
I don't think this error condition would be a warranty issue, but I'm not sure. It's a MAJOR hassle for me to get the car to the dealer.

My 2005 Prius with 116K on it has been having some uneven acceleration lately and today the Triangle warning light, the check engine light and the brake light came on at the same time. I had about 1/2 mile to go, so I proceeded slowly and called the dealership which had performed a routine oil chg two days ago. They said that if the lights weren't flashing then I could drive it. They recommended that I take it to AUTO ZONE and put it on the analyzer. This elicited these codes: P3019: no definition and P0A80: replace Hybrid Battery.
I have an appointment in 2 days and I'm wondering about a salvage HV battery since the car is 7 yrs old and over 116K miles.

This afternoon, after driving about 150 miles, I came home and shut off my 2001 Prius. It was sitting for about 20 minutes before I turned it back on to drive off. Almost immediately, the hybrid warning light came on on the MFD, the red exclamation mark light illuminated, as well as the check engine light, and the motor shut off. I popped the hood, and could hear a high pitched squeal coming from near the inverter. I called my dealer to ask the service department what I should do, and they just told me to bring it in and they will take a look at it. I live over an hour away, so I don't want to bring it there if I can avoid it. I then shut it off and let it sit for a few hours.
After reading about the possibility of the auxiliary battery being bad, I went and turned the Prius on, and then shut it off several times to reset the hybrid warning light (I had to do so in order to access the aux battery information through the MFD). It turned on without incident, and shut off fine, and after being reset the hybrid warning light shut off, as well as the red triangle light. Then, I went through the process of pulling up the battery voltage information through the MFD.
With the car off, and the lights and fans off, the battery voltage read about 10.0-10.5 V. With the lights and fan on, the voltage dropped to about 9.5 V. After getting those readings, I drove it down the road a little ways, just going about 20 mph. It seemed to work fine. The check engine light is still illuminated. With the motor running, the voltage reading was 13.2 V, and then when I got back from my test drive and shut it off, the voltage hovered at 10.6 V with the lights and fan on.
