Prius (2010-12) :: Sudden Lurch Of Power When Engine Is On
Sep 2, 2015
I've notice this several times when leaving from work to go home. The first quarter mile I will be starting off nice and easy, the engine is on and then suddenly a lurch of power. Now its not giving me a wipe lash! But I can defiantly feel it and out of the corner of my eye can see my passenger's head move back slightly. So not so subtle either. It will only happen once.
It is not going from battery to gas as I mentioned engine is already on. I am in eco mode the whole time. I am not hitting the gas any harder. And I am not going into the power band all the way right of the bar. I am staying steady in the eco area.

Twice today with cooling temps (45 during the day, closer to 30s on way home) while shutting down after being put in park my Prius did the "lurch forward and shudder." This is something new! Fuel has been purchased consistently from the same Shell station, she's garaged at night and MPGs are averaging 45... OK but nowhere near my great warm weather mileage. We are at close to 2200 on the odometer if my memory is working right - 2012 4 version. Happened once at the bank after work, once in the garage, level ground.
Not sure what is going on... this is new to me with a new car....

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.

I commuted to LA 2-3x a week. The mileage on my car is now at 90k. I have had an average of 40 mpg since new, but suddenly it began to drop. We took it to our local Toyota dealer and was told it was most likely a cable that needed to be cleaned. That was $160. It didn't work.

About three weeks ago while driving my Prius and accelerating the car jerked suddenly and warning lights came on. I was able to read the above codes with tech stream. The car still drives but has limited horsepower. The engine also does not seem to rev down like a normal hybrid. I have not had good experiences with the local Toyota dealer.

I am using a 2012 Prius and I was running around 23KMpL average. For sometime I am seeing my mileage around 17 - 18 KMpL. What could be the reasons for this ?
The only change happened in between is that I had a accident which I had to replace the front buffer.

I have a strange issue that just started happening. A whirring sound comes from the vent in the back seat I believe which sounds like escaping Air. Not like the last 2 years I've owned it. At the same time I noticed that the accelerator now takes a second to engage after I hit the pedal from a stop every time. Furthermore the engine seems to be over revving, as if engine braking. I've restarted the car a few times. I've checked all the fluid levels.

First time Prius owner Aug 2012. First 2 tanks of gas very impressed at 50-51 mpg. Then going slowly (10mph) through a parking lot I heard a strange noise on passenger side underneath the car. The best description is that it sounded like a steel lawn rake being dragged under the car on the asphalt. It lasted for about 30 seconds, then quiet and I have not heard it since. No sign of issues. No dash warning lights.
My next tanks rendered 47.5, 48.5, 46.5, 45.75 mpg. Then in the last 2 tanks suddenly at 41.5 and 42.75 mpg. This seems like a very major drop in mpg. I have been reading the comments regarding outside temp etc. and I will make adjustments. It just seems extreme and the "noise" is now making me wonder if some electrical component failed and is adding to the poor mileage issue.

I have a brand new 2010 Passat. I am unable to achieve a smooth start from stops and the car will lurch forward when I take my foot off the brake. Any small input from the gas pedal produces a jumpy start to the acceleration process. I have about 300 miles on the car. I bought this for my wife and she is very uneasy about driving it.

I have been driving 2013 model for five months. I noticed that whenever any front wheel rolls over cat-eye on the road and any sudden small bump then it generates noticeable clicking sound. I went to the dealer and they said it is normal and comes with all such cars.

Having problem with 2010 Toyota Corolla. Engine light comes on as well as VSC and traction control but the engine does not shut off. I loose power and engine runs really rough. I have to pull over and unplug my battery cable and the problem is gone until a week or two later same thing happens. My gas mileage is about 10 km for every 100KM city and Highway mix. The engine idle is also rough and sometimes when I try to do a U turn or get in and out of parking the engine shuts off.
Engine scanned shows P0010 and it could be three or for causes? My problem is that mechanics change one thing which costs an arm and a leg then if that did not fix the problem they say now lets change another part? I can not afford to fix them one by one and get charged for it as they replace one part at a time.

I have the not-so-uncommon grinding brakes problem too. In my case, however, there is a scarier difference: if I have to stop suddenly and hit the brakes hard, I hear the grinding and the car kind of shakes, but then as the car is decelerating, I will actually get the feeling that the brakes have totally disengaged, and the car will lurch forward! If I then depress the brakes quickly, they will engage again and stop the car. I've had a couple of close calls in heavy traffic when cars in front of me have stopped suddenly.
I guess that the grinding might be the ABS, but I've never heard of ABS causing your brakes to konk out completely! It's to the point where I'm scared to drive the car if I know there's going to be much traffic. I bought this Elantra last October to have a nice new car to drive my 6 and 4 year old around, so I'm very unimpressed, and scared, with the whole situation.

So today I ran into an issue with my idle, anytime I let the gas off the rpms come down but don't stop until the engine quits and the car dies. The battery warning light comes on until I restart the engine. Right before this started happening I was driving and all of a sudden the power cut out, puttered down to 11-1400 rpms and wouldn't respond to gas pedal, I shut the car off, restarted and it continued to cut power at 1400ish rpms. Let it sit for a few minutes, restarted and the car drove like normal.
A few miles down the road it started to die when no gas was applied. The car has a VF stage 2 SC with Um E85 tune. Seems to go in and out of dieing at idle, sometimes it will be fine and sometimes it'll die. I should also mention that I threw a coolant temp sensor code and haven't had a chance to replace it yet, but when I was troubleshooting the idle issue I cleared the stored codes and the coolant temp sensor code disappeared. At least I'm getting some good practice left foot braking for the time being.

I have passat 2007 2.0T , about 98000km. A few months ago, my vehicle randomly has hiccup with EPC light when I put on the pedal. Each times i put on the pedal my vehicle hiccups and EPC light on and all goes away when i put off my foot from the pedal. It happened randomly, so i went to vw dealership twice. They keep saying they could not find any problem. Coz as i said it happens randomly. I paid diagnostic fee but still the problem remains.
Unfortunately today i had the same issue hiccup like crazy with epc and engine lights. Also on the highway my baby 2 years old was with me when i drove, my vehicle lost power all the sudden, all most i involved an accident with following vehicle. I started the engine, vehicle moves but with the problem. I feel wheels do not spin properly or transmission randomly. What the problem is?

Lately having the following issues with my Tig.
When starting up the engine on cold start (or after having the car sit for about 30 minutes) after about 10 - 20 seconds; pretty much right after first acceleration the car all of a sudden looses all power. RPM fall down even when accelerating. Accelerating more only let's the engine stall more.
5-10 seconds later the engine functions normal again.... What problem could that be ?

Well zipping along the highway tonight, sitting on 100KM/h, and all of a sudden the engine loses all power. As luck would have it a fuel station was just closing (the only one for half an hour either side) and kept the lights on so I could have a look. The starter is nice and lively, and the engine is trying to fire, but just wouldn't. I asked a mate of mine in town to come out and give me a hand troubleshooting.
As it turns out, when the ignition switch is set to the "ON" position, normally the fuel pump primes the lines. It's only doing it intermittently for some strange reason, and not making it past the fuel filter (despite the filter being new). The temporary buzzing in the engine bay when the car is switched off is gone now too.
Now my question is - does this sound like fuel pump? I'm only used to the older fuel pumps in carburetor vehicles, not these fingle fangle electric things!

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'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)

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 get an intermittent spike in RPM with a lurch in the engine when I'm holding anywhere from 1500-1700 RPM. I say it's intermittent because it might happen three or four times over the span of a few seconds, and then nothing for a minute or two. I don't think it's the transmission because it doesn't happen during shifting, and I can duplicate the problem in D, N, and P. What could be causing the problem?

Ok here's the problem. I have a 2003 grand prix se 3.1 and a 1998 grand prix gtp series II sc. Both have the exact same problem running and both had overheating issues prior to. I can start either one on a given day while cold and drive them as if nothing is wrong. But soon as either one hits operating temp, I start to hear what sounds like a rattling or sputtering like sound from under the hood, accompanied with a sudden loss of power and then the engine shuts off. Now yesterday I attempted further diagnostics with the se model GP. I let it idle rather than driving it this time, and it ran perfectly fine for about 20 mins, started to make the aforementioned noise, I revved the engine to about 2000 rpm and it kept it from cutting off and smoothed, but the second I let up, it was off and wouldn't restart till it was cooled off. Same goes for the gtp. I'm really stumped on this one.
