Prius V :: Power Loss And Car Almost Came To Stand Still Several Times
Oct 14, 2012
Had first rain since purchase of Prius v almost got stranded as our Prius would lose power not allowing us to move forward, we were able to reverse and accelerated. While driving at a higher speed than felt safe, and in power mode, allowed us to get to pavement our Prius would still lose power and almost came to stand still several times. As we have to traverse this road daily we are concerned heading into winter. Is this typical?

I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.
Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?

I've been experiencing power loss at random times while driving, idling, With almost always flickering headlights on my mkiv 1.8t gti. Also on what always seems like the exact same spot on the freeway I'm losing all power to the wheels and it feels as if my plugs aren't firing for about 10 seconds Which causes me to bog down. At which point I down shift and play the throttle until my motor then begins running normally again.
I've semi recently replaced my battery and terminals, due to corroded terminals and worn out battery. Is is possible a ecu reset could solve this problem?
Also when the power surges during driving my traction control and hand-brake lights on the tachometer will flash and the car will beep three or four times (same as when the hand-brake on beep).

My 2007 Prius has 127K miles on it and is idling rough, especially noticeable when the car isn't moving.
I've changed the 12V batteries, spark plugs and used cleaner on the throttle body. Car acceleration has improved but fuel economy and the rough idling remain unchanged.
I have an ELM327 and the Torque Pro app and the car is throwing off no codes.

What is the weight of motor planning on doing studs in future and need to know what size stand and picker to buy. Pulling cab isn't option cus no lift and stand was planning on buying one 2 times the weight so it's good to hold for the weeks to get it done around work.

I am doing heads studs and gaskets on the truck. I forgot to remove the stand pipe and started to lift the head off the truck with the engine jack. Well i bent the stand pipe and the port to the bock was a little loose. Tightened it back down and it seems ok. Could I have damaged anything by doing that? how is that all connected to the high pressure oil pump? I just want to make sure i didnt damage anything by doing that and since im already here I would rather make a fix instead of needed to tear down again.

I've been having trouble diagnosing a loss of throttle at seemingly random times. Sometimes while driving, especially after driving for more than 20 minutes or so, I will experience a hesitation while on the gas pedal as if I have taken my foot off the gas. It makes it impossible to drive until I pull over and unplug my TPS and then I can drive fine in manual mode. Then the next day I can plug my TPS back in, drive around fine for a bit before the hesitation happens again and then I have to unplug the TPS again and drive in manual mode. It doesn't make sense to me why it takes a bit for this hesitation to begin and why unplugging the TPS and driving in manual mode seems to fix the problem.
I've recently replaced my crankshaft position sensor, idle air control valve, purge control valve solenoid and TPS. When I recently placed the TPS, the hesitation problem and another problem I've been having recently, a high idle in park, seemed to be fixed, but then the hesitation problem popped up again. When I unplug the TPS, the hesitation disappears and I can drive fine but the high idle in park problem is back! I'm suspecting some sort of wiring problem to the TPS. I just went on a 100 mile camping trip in manual mode no problem, but I can't be driving around forever with no TPS.

Prius Loses Power While Driving on Interstate.

I have an 07 Prius with 90Kmi (bought new) which now loses power while climbing sections of mtn passes. Battery meter shows 1 purple bar and cannot go faster than 50mph. No warning lights or fault codes. Never an issue before & intermittently happens around town. 4 dealer visits and extended tests with TMC field techs have allowed them to duplicate the problem at least twice. Interestingly Toyota doesn't know what or how to fix this.

I bought my 2001 Prius used about a year and a half ago and had no problems until the past couple of months. On three occasions now, the triangle warning light has come up on the screen while I was driving and the car wouldn't accelerate when I pushed the gas pedal.
Fortunately, the I was able to coast to the side of the road on each occasion, and when I turned the car off and restarted it, it worked fine. The first two times, it happened on the freeway after a lengthy drive and while traveling at about 70 mph. Today it happened on a surface street, but after I had been on the freeway (in gridlock) for nearly an hour.
I should have dealt with this sooner, but somehow every time it has happened, it was on the weekend and/or when I was out of town, so I couldn't immediately take it to a shop, and since the car started back up immediately and ran fine after each occurrence, it didn't seem urgent.

I recently bought a 2004 Prius with 104,000 miles on it. When I try to go up into the mountains I only get a few miles or up to 1,000 to 2,000 ft. elevation (from 300 ft. starting) and the battery level gradually drops from 6 bars to 1 bar. The red triangle light and check engine light comes on and the car speed gradually begins to drop even if I continue to press on the gas pedal. I have only gotten down to about 35 MPH from 60-65 mph before stopping and turning around. Within a few miles of turning around the light goes off and the battery goes back up to 6 bars and works good going down hill. The dealer I bought the car from has been working with me to figure out the problem but so far we have not figured it out. He has replaced the main battery as well as the inverter/converter. The mechanic was with me on a test drive to the mountains and had his car computer plugged in while we drove and experienced the same thing. It gave the code for the catalytic converter so we changed the entire CC/muffler (one long piece) and still got the same code. The battery indicator on this car has never shown more than 6 bars. I'm not a Prius mechanic but I personally think it has a bad "Gas Engine" or something wrong with the gas engine. How do I tell if the gas engine is bad or has a problem?

I have a 2003 Chevy Malibu, V6, 3.1, auto, 140k miles. Car started out with code 0420 with no noticeable symptoms, but then added code 0303 (miss fire cyl #3) with loud knock (mostly after warmup) and loss of power under load. Now internal loss of coolant (no puddles or external drips). Changed plugs and wires - no change - all plugs looked good with no sign of contamination. Questions - if this is a valve/piston/lifter problem (which would explain the knock, miss-fire and loss of power), why would I get the loss in coolant? If the loss of coolant is fouling plug #3 (which would explain the coolant loss, miss fire and loss of power), could that give me the loud knocking? I don't see how a valve/piston/lifter issue would cause a leak in coolant but I also don't see how a coolant leak into cyl #3 would give me such a loud knock. Do I have two different problems? If it is a leak into cyl #3, is there any way to tell if it is the intake manifold gasket (which leaked before and was replaced five-six years ago and which I could do again if I had to) or a blown head gasket (which I don't think I could fix or afford to get fixed)? Engine will occasionally get hot (but not overheat).

Purchased a used 2006 prius with ~180K miles on it from south bay a few months ago. At the time of purchase the guy warned us that it 'ate' motor oil.
After 2 months of driving without issues (driven couple of hundred miles), on an uphill road the engine overheats and throws the red triangle, vsc and check engine lights on the dash, along with loss of power. After cool down I check oil level and sure enough it is low, since this is on top of a hill we essentially coast all the way back home without any real issues. Once home I top up the oil. I do a test drive around the block without issues (no loss of power) though the check engine/red triangle/vsc lights are still on. But after I take it for a longer drive the loss of power returns.
Since my bluetooth obd2 connector wasn't working I borrow one from my friend and try to get a read. Unfortunately the thing puts out no obd2 error codes. Living in the bay area I apparently cant just take it to an autozone, to get code readings. I take it to meineke auto repair, they too are unable to get an obd2 read, and want to charge me $100 for a full reading, which I decline.
I do a few diagnostics steps including 'resetting' the computer by leaving it off of the 12v battery for a few mins, this clears the red triangle et al on restart. I do a test drive, at first everything is working just fine, but after about 10 mins or so of driving the red triangle/check engine/vsc lights returns, along with loss of power. (under ~20 mph only, cant go uphill).
Take it to a mechanic and they come back with code: "APOA92. Trans Axel issue - MG1 performance is off. Measured torque is different than executed torque, enough to be a problem. 95% sure it is the transmission." I still haven't checked the 12v battery.

I drive a 2007 Prius, I just purchased it about four months ago. Today after filling up with gas I drove about 60 miles and suddenly three lights on my dash came on. The all system light (the red triangle), the check engine light as well as the VSC or VCS what ever way it goes, my electric batter was also low on charge having only one bar(my car is not a plug in, the battery is recharged by the engine) then the car lost all boost and while pressing on the gas it was not accelerating. I pulled over and put it in park so the battery could charge. It charged to half way, however the lights stayed on.
My car then started running really rough, I am still in park at this time. I put some gas stabilizer in my tank because I thought maybe I got some bad gas. I left my car sit for about five minutes before turning it back on. All the lights were off except my check engine and my car started running normal. Then about three minutes later all the lights came back on and the car started running jerky again. When I push the gas to move I can, however I've only gone about four feet because it is running so rough.

So I got my 2012 Prius started worked for a while, then loss of power and got this code P0A0F. A big black cloud also came out of the exhaust. What it means?
Just changed the oil, there was way too much of it, it also smelts like petrol and now I'm going to get new spark plugs as they are in very bad condition and are wet.

I had my snow tires removed yesterday. My mechanic who is great said everything looked good. I drove down the highway at 55mph lost power, was able to pull over. He my mechanic had it towed. I'm wondering if changing the snow tires would have anything to do with it?

Was sitting in my car on my lunch break playing the radio and had my seat heater on, and all of a sudden my radio kinda went staticy and died and my car completely died. Had to power it back down then back up to get it running, battery didn't show very low, but when I went into start mode (non accessory) it immediatly started the ICE and charged.

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.

Really scary, had my son in the car. Dash read "Check hybrid system". Reading some posts make me think that it may just be the 12V. Had it towed to my house.

I have a 2005 Prius that has been very reliable! With the exception of oil changes, brakes & tires I've only needed to replace the Inverter Cooler Pump, which was under recall (about 40K miles ago). Without any prior problems, the triangle of death came on along with the other dash alarm lights. I noticed an immediate great power loss & the fan behind the rear seat came on.
I stopped the car & let it sit about 30 minutes. It started right up & I drove it home. It felt sluggish & the max was 50 or so , I didn't want to push it, so I stayed below 45 mph. It had very little power, the engine ran constantly, with no battery assist. The drive home was approx 40 minutes. When I tried to start it a few hours later, it started immediately. The warning lights are still on, it runs rough upon start and the rear fan comes on immediately.

With only 356k miles on my 06, I'm now getting a sudden drop/loss of power at high RPM. At about 80mph on flat land (or about 60mph up hill) if I try to accelerate the power drops off as a fluttering sound starts (not engine knock). The fluttering sounds like 6 inches of celophane tape flapping in the wind at highway speeds.
I just cleaned my K&N air filter, but the plugs, injectors and fuel pump are original. I ran 1 can of injector cleaner (SeaFoam from O'Reilly) with little to no improvement. I'm guessing it's the fuel pump/pressure, since it runs fine at lower RPM, with no loss of mpg or power (still 50mpg average). I know the fuel pump is in the tank ($400 in parts alone). I'll see if I can measure the rail pressure with Torque and my CANBUS scanner.
