Prius (Gen 2) :: Power Loss And Low Battery - Cannot Go Faster Than 50 Mph
Jul 2, 2011
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 am trying to diagnose a problem with a friends 2002 f350 7.3L truck. the engine has approx. 140,000 miles and is all stock, no programming or aftermarket parts. Anyhow, he said driving down the road the other day the engine all of a sudden lost power and the truck wouldn't go any faster than 45mph. he said taking off from a stop sign, the truck has no power and takes forever to get up to 45mph. after this issue began, he has changed the fuel filter & screen, air filter and fuel pump. The check engine light if OFF, no active fault codes.

2003 Explorer Sport, 4.0 L, 84K miles. Car just fell out of extended warranty and has been serviced exclusively by the dealer.
While driving, I experienced a sudden bog down and inability to travel faster than 20 - 25 MPH. The more pedal you give, the less power. In neutral, free revs will not go above 3000 RPM at full pedal and will rise and fall between 2000 - 3000 RPM. The next day all is normal again. This happened twice now and I am not sure why. No CEL, no stored codes.
Plenty of pressure (felt by hand only) out the tail pipe except when fluctuating during free revs. There doesn't appear to be any vacuum leaks. What I can check to correct this? Could it be bad fuel or water in fuel?

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.

Have 1000 miles left on the 150K CA battery on my 2009.
First, I can no longer enter EV mode with the ev mode. It always says cannot change into ev mode right now. In the past, that only occurred during the warm up cycles. Now it always says that regardless except if I try when first powering on before the engine starts. In that case, when it was working, it would switch over and the MFD would change to show the battery. Now nothing and the engine always starts.
Also, the battery charges and discharges much faster than it used to. I can barely get a 1/4 in stealth (feathering the throttle to keep the ICE from kicking on) without it going from 8 bars down to 2.

My 2007 Prius has 120,000 miles. I live in a mountainous area. I need to climb 3 miles at 6% grade to get out of my neighborhood. Lately I've been noticing the traction battery loses charge fairly quickly and I've been thinking about replacing the battery. Much of my driving is in steep hills and I run a full charge cycle many times a day, so I guess I should expect some loss of life.

What the problem is with my 94 Saturn Sl2? It seems to loose power going up hill. Also I have put in a new alternator and battery, because the battery would go dead after driving for a while. ABS light remains on as well. Also have pinging noise coming from below the emergency brake area, after I have driven it for a little while. Even if it sits idling at times, it will drag down the battery or something, because it will kill and go dead. Could there be a short somewhere?

What is "reasonable" for the loss of capacity of the Prius Plug in battery? Ours started out with a max at 11.7 miles when fully charged. After 6,000 miles and 7 months it is down to 10.0 miles. This seems like an excessive loss to me. I have read the tips for maintaining capacity and we don't do all the them. e.g. we charge out battery asap so it will be ready for the next trip. Our schedule is not fixed enough to determine when the car will be needed next.

Is the remote starter going to drain your battery faster? is it why a lot of CL members having a battery problem? My friend said his dealer told him so that he didn't get a remote starter for his car. Is it true?

When I accelerate to merge onto the highway or pass my battery light blinks as well as my headlight flickering and a slight loss in power. My car has 140k miles on it, original battery which seems to test fine on my charger. I just change the spark plugs.

Prius Loses Power While Driving on Interstate.

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 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).

Today my Prius surprised me. I drove it out of the garage and it had 2 bars charge. After a few secs, as usual, it fired the ICE. Ambient temp was 21C/70F. The ICE stopped after only 1 min as per 1-min fuel consumption screen. Maybe it was a bit longer (more than 1 but surely less than 2) - it never warmed up that fast after a full night cooling off.

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.

Experiencing excess wind noise at 60 mph and faster? You would think a vehicle that has a low drag coefficient would not have wind noise issues.
