Prius (2001-03) :: 2002 - Sudden Loss Of Power While Driving Followed By Alert
Aug 27, 2010
I've been having this problem where as i'm driving (mostly highway) all of a sudden I get the feeling like i've let go of the gas pedal but I haven't. The mpg meter goes from about 40 to 100 as if its on straight battery power and I have to really press the pedal down to get any decent acceleration. Once in awhile i'll get the big orange triangle warning and the little pic of an exclamation point in an outline of a car. But after a day it may go away.
One time it didn't and I brought it in. I spent 80 bucks for them to find nothing wrong and say the alert had something to do with an oxygen sensor (its was awhile ago, i dont quite remember exactly)

Last night was getting down to freezing. I drove out of my buddy's driveway, stopped to close the gate behind me, put it in gear and started to drive away, about 5-10mph. I left off the gas as I rounded a gentle curve, then got back on the pedal as I exited the curve. All I got was a revving engine, as if I was in neutral. Checked to make sure I was in gear, and same result. I stopped, engine running, and put it in park, and then back into gear. Nothing. Drive, low, Reverse nothing. I did see the rpm change slightly. engine runs normally.
No fluid loss, no mechanical noises indicating something breaking. No weird smells. Fluid level is as good as I could read on that crappy trans dipstick. Truck ran flawlessly up until that moment. the transmission is a BTS with about 100K, so I'm fairly certain it's not the mechanical diode notorious for that year. My problem description does not seem to fit the failed diode anyway. I did run across a post that better matched my problem description and that was the transfer case motor. I have 4WD, but was not in 4WD at the time.

I've been driving my V10 for 3 years now without a problem. The other day, while I was on the Highway in Italy driving at around 140KM/H, I suddenly had a loss of power. I could continue to drive the car, but I had no more tork... I stopped at the next gas station, turn the engine off, turned it on again, and the car drove normally again as before. About 200KM later the same happened again...
I went to check with the dealer - he hooked up the car to the computer - and told me that they had to change both turbos... What I find weird is that when I turn the car off and on again it works again. If the turbos would be defective, they wouldn't work again just by turning the car on and off. I think that it is more a problem with the turbo controller and if that's the case why change both turbo.

Driving in sunny so cal yesterday never a problem with the car just an oxygen sensor- I was cruising along at 75 and all of a sudden the oil light comes on - immediate loss of power and i pull over to the side of the road and shut it down. try to restart and it just clicks.....tugged on the crank through the wheel well and it will not budge...oil is ok and plugs were pulled and they seem fine....oil pump...fuel pump....starter hopefully something simple and inexpensive I hope.....what is the difficulty in changing out the starter and could this be the issue?

On my '03 Santa Fe 2.7, this has happened twice, with 500 or so uneventful miles in between. At highway speed, it just all of a sudden loses power and will only go about 50 mph with accelerator to the floor. When you stop & put in neutral, it only revs to about 3000 rpm, with pedal to the floor -yet idles fine. Then when you shut it down, wait a few minutes & start it back up, it's fine. Is this a fuel problem or what?

I was driving down the road and the car was driving great. all of the sudden I heard a clunk and the car lost power and started shuddering. I made it home and cut the car off. When I start it now, the car runs rough and stalls out. I can't get it to a place to check the codes so I am trying to self diagnose. I was thinking it might be the MAF so I took it out and cleaned it well. there is still no change in the way the car runs. it seems like the fuel isn't getting to the engine as I put my foot on the gas pedal it stalls out. I'm not too excited about buying a throttle body if it's the MAF. It could possibly be something else.

This just recently started happening just shy of 200k miles, 14 years. While driving down the road, suddenly notice a power loss or no power, i.e., no motor output. Sometimes the just the ICE won't accelerate, sometimes it's both ICE and Electric motive force. When this occurs, the Brake and ABS check lights turn on. After a few seconds, to 10's of seconds, then the motive power reenables and the Brake/ABS lights go out. Often the cars continues on with no repeat. Testing over a few drives, it seemed to only do it during the warmup cycle when coolant was near 160-170.
However on a drive in the afternoon after it occurred in the morning; with ambient around 30 degrees, windows cracked, interior heat off, it didn't occur on the 15 minute drive, mostly freeway speed, even after about 10 minutes and cranking interior heat on. No codes are registered when this happens. I used Torque Pro and monitored things like throttle position and such, and things there seemed normal. Eng rpm dropped under 1000rpm and wasn't steady. Watching the MFG the power flows responded to the throttle (pushed/released) as if the engine was still doing what was asked (go figure, the display shows what is commanded, not what is occurring?).

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 have a 2001 f250 super duty extended cab with the v10. Over the past week it has been running fine and it will all of a sudden lose power and dies. I've been able to start it back up once right away and a few times it started up after a few hours of messing with it.
So, after the truck dies it will crank and crank but will not start. We have checked fuel pressure and nothing. Then we applied direct current to the fuel pump and it turns on. Then we applied direct current to the fuel pump slot in the fuse box and got a fuel pressure reading of 40 psi. But when we crank we have no pressure.
When we apply direct current to the fuel pump slot in the fuse box the truck will only crank and not start.

My excursion suddenly lost power after sitting in a long traffic jam. I have a scan gauge II set up and didn't see any signs of over heating however when I went to accelerate back up to highway speed my motor revved up to 3000 rpm and just lost power I ended creeping on the side of the road at about 15 mph and barely maintaining that. The motor was not willing to revv up. I reached a spot to pull over and shut it down for about 15 minutes and started back up and drove off with no noticable issues. I have 211,000 miles on this motor and I am going to change my coil packs, I think they have been there since the truck was sold new....I changed four of them to address a miss and have six left, I will also be changing my fuel filter. We are about to pull our camper across country....about 1400 miles..

I have a Prius 2005 with an Engineer 4kwh kit installed [v4 bms]. Lately, I have experienced several instances where the Prius suddenly looses much of it's traction power and the engine races, and the red triangle and engine service lights go on at the dashboard. This happens with the kit turned on, and often after a few kit on/off cycles to get more ev mode. The Prius battery is sometimes low, sometimes not, when this happens. Not sure if it also occurs with the kit off.
The Prius seems to retain some traction power up-down by the throttle pedal, but most power goes missing. On the other hand the engine races and does not seem to power the wheels or vary by throttle. When I pull off the road using brakes normally, and turn off the car/engine and restart [kit now off], the car seems to reset and can resume driving normally, but the error code lights [triangle-engine] lights stay on.

So I replaced my battery about 20k miles ago, so I know that's fine. I always throw a P0420, but I'm told that's fine too. So I was driving, and I lose power suddenly. The red triangle comes on, and I plug my scangauge II in, which tells me it's P0121, or the throttle body sensor. I reset the codes to make it home - my battery DID charge just fine on the way home, making it up to a 63.5 state of charge. Now when I start it, and press the gas, it tends to rev up, rev down, and repeat. I haven't gotten the red triangle again yet but I also haven't driven it since then.

I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?

My friend has a 2003 4 cyl auto Elantra. His problem is strange, while driving the car is normal for maybe 1 - 5 hours then out of nowhere the car will only go 15-35mph and no matter how much you press the gas pedal the car will not accelerate. It is a bogged down loss of power not like it's just stuck in a low gear. This has been happening for a while now but now it's happening all the time and very frequently. Before he could shut the car off for 5 minutes and it would be ok for another 1-5 hours. It got so bad that he can only go 20 miles before it happens and now it seems the longer he lets the car sit off the longer he can go before the problem happens. Hyundai has had the car for a week and still have no clue what the problem is but it has not happened while they have had it. There is no CEL or any stored codes which is making this really hard.

Ok, so I was driving normal highway speeds and all of a sudden, I realize a major drop in power. I pull over and restart it and it changes nothing. Now when I floor it, it takes 20-30 seconds to get to 90K.
I checked the air filter... Nothing. Used a code reader... Nothing. Then I decided to pressure test the cylinders... Nothing, except now the check engine light is on.
The Ol Dub is still drivable, but it is extremely slow and rough at idle. I am thinking it might be a MAF or fuel filter.

I own a 02 fwd v6 Santa Fe that just lost power on the interstate. It will go about 20 miles an hour and basically does not change gear unless it is in manual mode. I was able to drive it to a local repair shop but they are having trouble figuring out what is wrong with it.
First, they told me the plugs and wires were bad, changed those and still no power. Next, they told me it was the fuel pump, change that and still no power. Next, they said it was the catalytic converters but the said they unhooked them to test the theory and it still had not powered. They said it may need back pressure from the cats so that may not work. They want me to buy them but they are very expensive especially on a guess. Next, they told me if that does not fix it is must be the transmission. Will the cats off keep it from running due to back pressure? Does it sound like a transmission issue or could it be something else?

2003 Santa Fe - Loss of power while driving on highway. Dropped from 60 to 15 MPH in matter of seconds. Feels like a couple of cylinders (3.5 liter) are not working.

I have a Santa fe 2002 crd 2.0 4x4 and recently had a lot of black smoke and a loss of power when driving, it starts fine but when revving it blows black smoke from exhaust and has no power to pull away, been told its possible turbo problem or fuel problem.

Bought my Santa Fe GLS less than 2 months ago and ran fine. Last week, went to store no problems and then went out 5 minutes later, put it in reverse and it stalled. I go to the store, and it lacks MAJOR power.
Now, if I leave it alone for a while it will normally start right up. While idling, everything seems fine. Then my "ghost" takes over the vehicle making it less responsive to the gas pedal. Also, at 3000 rpm, it sounds like its skipping a cylinder. When reading the gauge, it skips between 3000rpm to abut 2800 rpm.

I just had my '12 GTI's 40,000 mile service done about 2 weeks ago. I put in a K&N air filter the day after the service. The only thing I noticed about the car after service was that I could smell coolant, they either spilled some or its burping some cause it was filled past the max fill line. Outside of that everything was copacetic until yesterday morning.
On my way to the gym with cruise control on ~74 mph on the highway I had sudden power loss, EPC light came on and power returned although felt reduced. When I left the gym it was off and I made it about a mile when under acceleration it hit at about 3k rpm, again sudden power loss and EPC light, power returned reduced. Drove about 5 miles to work and did a little googling with a million results.
When I left work to go home I made it about ten minutes into my drive before it happened. This time the CEL came on. I was able to drive home and back to work again this morning but I keep having power shutters followed by the EPC. I haven't had much time to dig into anything but I checked the connection of the coils and the intake connections with a flashlight at 4:30 this morning. Thinking it might be the MAF only because I recently installed the K&N and have read the oil can kill MAF's and I might stop to get a can of cleaner on my way home to try that route.
IF that doesn't work maybe I can get it on a Vag Com in the next couple days to get it sorted out.

I have VW99 Passat 1.8L Turbo, automatic with 170K on it.
My car shop changed engine oil yesterday with 4 QTS of Mobile 5W40. Now, when I check my dipstick today, on level surface, the oil level is way too high on dipstick kink [the cross-hatched mark]. I run the engine, shut it off, and let it set for 3 min, but still the level is too high above the Mark. It wets the dipstick almost till the top of its Head.It was reading High when I first checked it, this morning, before starting my car.
It seems the oil is 'overfilled' or showing over filled; and the engine is about to throw it out from "filler cap" where Dipstick goes in the engine. I saw him using 4 cans 1 QTS oil, which I bought, into my car. They did change the "oil filter" at the same time?
Now, my car looses power while driving. When I accelerated from a stop/light, car slows down or limps. The car suffered a sudden loss of power.It runs awful for about a mile but smoothed out after acceleration.It feels like the car is running out of gas for a few seconds, then all of a sudden it kicks in. The car still drives ok though - No error messages/warnings on dash,CEL, no smoke, no hissing. I actually don't see engine oil thrown out or leaking though.
I don't know if the shop drained the "intercooler" while changing the oil, also I know nothing about its importance to my power loss issue. The net search manual/states "The engine oil, above the level, can be drawn into the crankcase ventilation system, and enter the atmosphere via the exhaust system". But it does says about damaging the engine/car.
Should I be worried about the damage to the engine?
