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) :: Lost Acceleration - Warning Lights And Fault (DTC) Codes
2008 Prius recently lost acceleration (would only creep along) and soon stopped. Warning lights - red triangle with !, red split car on mid, check engine - came on. About 10 minutes later the car started and allowed my daughter to creep the last 1/4 mile home. DTC's - P0A3F and P2196. Was recently gassed up, so checked gas cap, thinking it may have set the oxygen sensor code. It was loose, tightened it. Pulled the EFI fuse for a couple minutes to reset the codes (not sure it did). Put the smart key back in and warning lights came on again. May have to take to dealer, but would like to have some notion as to what's causing this. Possibly related -- a couple weeks ago the 12V battery got drained overnight. Pulled it and recharged and everything seemed to be running fine.

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.

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.

2009 Mazda 3 Since a nasty cold snap in Northeast, instrument panel has gone crazy. The meter showing RPM's works but 0 on the speedometer- dead. Gauges have been all on for a couple weeks. Just noticed now the power steering is gone. All lights seem to work normally and heat/defrost works. Radio works. Haven't noticed if odometer is working or not.

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).
Prius (2004-09) :: Warning Lights Came On While Driving But Did Not Lose Power
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.
Prius (2004-09) :: Warning Lights Came On - Gas Engine Loss Of Power?
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.

No warning ...would not start. 24,000 miles on a 2011 PRIUS. Tow truck jump started it and I drove 1/2 mile and emission light, then red lights came on and I lost power? Towed to the dealer. This is my 1st hybrid and I have no clue what is wrong. The tow truck driver mentioned the hydrocell?

I had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.

My company has a fleet of about 20 2007 GL AWD Santa Fe's. A few of them have had a strange problem....AWD, ESC, and check engine lights will turn on and they will lose acceleration of the vehicle. The dealership has said that it is a problem with the electronic throttle. Apparently it has been quite dangerous for some who have been driving at highway speeds and lost acceleration.

When I turned my Prius on today, the following warning lights remained on:
red "BRAKE"
yellow "ABS"
yellow "VSC"
yellow exclamation mark inside a circle inside parentheses.
It drives fine. After driving it a bit I tried turning the car off and back on a few times. The lights still remain on.
Prius (2004-09) :: All Warning Lights Go Off
Mine did. I was driving on the highway and pretty much every warning light went off. It was like the space shuttle crashing back to Earth. Freaked me out. Cruise control stopped working also. But I was able to get home safely.
So first, I tried AAA just to see if the guy would know something, but it was way over his head. He did notice my aux battery was failing, but not much else. Then I found a service online that comes to your place to do the work, and they sent a guy out on a Saturday and he read the codes, and did a full visual inspection, and yes, something was up with the cooling system. He suggested I have the dealer look at it because flushing the system is VERY important apparently. Should be done every 50,000 miles.
I was so worried it was the hybrid battery; we all know what that means! So I had the car towed to the dealer (don't drive if your Master/Hybrid light comes on!) and they said, indeed, the pump was gone. And, of course, they found a number of other things included the dying aux battery. It took them 4 days to get the damn part in stock. At least they covered the car rental for me.
Prius (2004-09) :: All Warning Lights Came On
The other night, went to start the prius and nothing happened except all the warning lights came on! So took the foot off the brake pedal and sat there for a minute trying to figure out. What the heck happened?? Tried a couple more times and then suddenly it was fine and it started! Now I have to mention that the outside temp was around 16*,,, not sure if that could have caused this strange reaction?

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.

So am i the only 200,000 miles prius owner on here? I have an 05 toyota prius, purchased with 44 miles on it. I now have 218k miles. All I've replaced was an o2 sensor and a few other minor things. But it died last thursday, had it towed to my house, still don't know the extent of the issues. I had the following codes P1116, P1121, P3193. I was driving on the interstate and all the warning lights came on and i lost power as i got over. Jumps would only allow me to turn my lights on and dashboard, but the engine doesn't start.

View 19 RepliesPrius (2004-09) :: Getting Some Warning Lights Intermittently?
Two days ago the first sign of a problem was the AC going out, followed by the red warning triangle and check engine lights coming on about 10 minutes later. Checked coolant and topped oil off (it is due for an oil change, btw) and drove about 20 miles home, no problems despite warning lights. Even the AC started working again. A little while after getting home, I started it up......no warning lights. I thought all was good.
Yesterday, no issues. Didn't drive more than about 15 miles though.
Today, took roughly a 25 mile roundtrip with no problems. Made the exact same roundtrip about 2 hours later and the red warning, VSC, brake system and check engine lights all came on (see pic) about 10 miles into the trip. I immediately turned AC off to remove that stress. No changes in car's behavior, however. Made it back home, turned car off and waited about 20 minutes. Turned it back on and only the red warning and check engine lights came on. 2 hours later....same two lights are still on.
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.
