Prius (2004-09) :: Warning Lights Came On While Driving But Did Not Lose Power
Jul 19, 2011
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.

I have a 06 sonata v6 with 120k. Today while driving the car started to lose power then the lights on the dash board flickered radio went nuts and the car lost all power. What could be causing this? Moved battery a little bit and got power back but then started driving and it did the same thing. I did have the heater on 2. You can feel it lose power while accelerating.

So I was driving and suddenly three warning lights came on. The Master warning light (Red triangle with !), Check Engine Light and the Hybrid System warning light (Car with !).
My AC works fine and I was able to shut it off and start it back up with no problem. I also did see a difference in driving.

my much adored 2006 prius just got three warning lights as i was driving and slowing down at a light. The big red triangle- "Master Warning", the Brake System Warning, and also, the Hybrid System Warning. It was like warning lights galore... i'll bring it into the dealership first thing tomorrow, but any clue what's going on? I regularly maintain it. The only other thing that ever went wrong with my car is that the touchscreen quit working years ago, and i refused to spend the 3k for them to connect a silly wire. Why my lights went on and is this something serious?

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.

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.....

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 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.

I just wanted to share with you all a cautionary tale about belt tensioners and idler pulleys. I am now a firm believer in installing the aforementioned items when you replace your drive belt. 15000 miles ago I replaced the drive belt and didn't heed the warning of some here on the forum.
For the last month or two I have noticed what sounded like road noise which I dismissed because I had just had new tires installed that had a more aggressive tread pattern than my previous tires, I also noted that the ECT had been a bit higher than normal, like running in the high 190's to low 200's on average.
Well while driving today I get the alternator warning light and lose power steering and soon after the brakes got stiff, this was followed by ever increasing ECT which got to 242* before I could get it off the road and shut down. It is too early to tell if the noises and the ECT temp rise were the result of this tensioner going out...
For what its worth the only tools required were a 10MM end wrench and a bit of skin to get the job done.

Our 2006 Chevy Tahoe will at times while running the speed limit (or slightly above) will suddenly without warning lose power. All the gauges remain in good ranges. This will happen without warning and not on a regular basis - sometimes going six months without happening and then happen three times within thirty minutes. The stability system warning message comes on as does the check engine light. Also the traction control warning light comes on. We can pull to the side of the road, turn the engine off for a few seconds and then it will start up again and run well with only the check engine light on. When this happens, the rpms will drop and go under 1500 and the engine will still be running, just without power.

Started my '07 this morning and after about 10 feet of driving forward all these lights came on. It also said PROBLEM across the digital AC/Consumption display before Problem disappeared and that right box showed up in the top left corner. The giant red ! triangle is solid, NOT flashing.
May not be related at all, but last night when I started my car to come home from work the gas pedal felt non-responsive as if it was trying to use battery power but it wasn't there. I turned the car off, back on, let it idle for 30 seconds before driving and I drove home without a problem.

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.

Will not start the ready light of any dash lights for that matter work.. tried to jump it.. nothing working. What the he'll can cause thus.. I'm about 500 miles from home with a car just parked.

I have a 99 F 250 7.3. It runs fine at idle even for a long time. When I drive around the block a couple of times it will start chugging and lose power and shut off. I have been mixing fryer oil with the diesel. I changed the fuel filter, oil change, crank sensor and fuel pump. I added 15 gallons of diesel and diesel treatment. Pulled fuel filter and bowel is full I'm not sure where to look next.

If you are driving in 2wd and lose power to wheels is it possible the transfer case is the problem and not the transmission? This was in a 1995 Ford Explorer 4x4 automatic transmission.

My daughter has a 1995 Grand Prix - 3.1. The car has an intermittent problem that can go 2-3 weeks in between occurrences.
It runs like a top, but will suddenly lose power while driving and die completely. After a while it'll be fine. (starts up again.)
The lights will flicker and give a bit of warning before it dies. I had both crankshaft sensors replaced a month ago and I though that would do the trick.

I have a 2005 B6 TDi 2.0 sports 140bhp passat and have encountered a glow plug lamp problem. The light came on while i was driving and the car seemed to lose power. We then switched it off and restarted and it was fine but then the problem recurred a few days later. The light has come on both times when i have accelerated on the motorway. What it could be?

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.

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.

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?

My vr6 some times loses its power but it's weird because the check engine light does not appear. It does for like 30 seconds then it goes back to driving normally.
