I just turned 3000 miles on my C. I started the car and the engine chugged and knocked like I have never experienced. I turned off the engine and restarted and no problem. What gives?

View 10 RepliesAfter starting my Prius the engine was knocking and shaking. After running the engine for 30 - 45 seconds it operated normally. The car is always parked in our garage and the outside temperature was approx 32 degrees or a few colder. I have 30750 miles on the car.
View 1 RepliesA few months back, I posted a problem with my '01 prius: engine knocking for @30 sec when first starting up. Does NOT happen on first start of day, only on subsequent ones. Random misfires not corrected by changing coils/plug. It's been in the shop for awhile, and no diagnosis. I'm ready to sell the thing, unless there is a quick fix. New hybrid battery 20# miles ago; used transaxle 10# miles ago (with 1.5 yrs left on 2 yr warranty); new tires 10 miles ago. Has 185,000 miles.
View 1 RepliesThis is my new Prius C's engine warming up in the morning. The engine shakes once when starting up and I seems to be able to detect a slight knocking sound.
View 4 RepliesThe engine starts with knocking, rattling, and vibration that lasts for about 5 seconds. It seems to be an intermittent, rare event. With nearly 250,000 Prius in the North American market and the onset of cooler weather, it is time to see how frequently this occurs.
View 19 RepliesI posted about this back when I bought it back in Feb. and I thought the problem worked itself out but its back. When the temperature drops below 55 degrees or so, coming from the passenger side of the engine there is a chugging or knocking sound, more so when RPMs are high.
I had no issues with it all summer, but now that the temperature is dropping I noticed its back. Is this something I should worry about? What could be causing this? I had the same engine in my 07 and it never did this.
My car has less than 500 miles on it. Yesterday when I started it, I heard a knocking sound. I only put 87 octane gas in the car as the manual said 87 or higher. I don't know if I made a mistake putting 87 in there.
View 4 RepliesI have recently noticed that my Azera makes a "knocking" sound right after starting the engine. It just about a dozen of fast short knocks one after another and it is gone after 2 seconds (like a diesel engine started on low temp. It appears more often when the engine is rather cold.
View 27 RepliesWeird noise I am hearing with my mothers new Elantra she just picked up. When starting engine has a knocking noise, not kinding. Letting motor run for a few minutes it goes away but is concerning. I was wondering if there is an issue with the MPFI engine which i believe is new this year which replaced the GDI engine. Definitely does not sound normal to me. to me it sounds like a rode knock or hydro lifter issue. Are these engines known for this. My mother traded her 2012 civic for this with 4500 miles. She did not like the seats and dash board layout in it and we got a good deal on this car.
View 17 RepliesLately, the ICE has occasionally been vibrating or knocking a bit just before it shuts off. It seems to be more noticeable when the car has just stopped at an intersection.
The humidity here is higher than normal for Colorado. The temperature is in the 80s F, so it's not a cold weather issue.
I've been driving through more water than usual due to the recent flooding here. I wonder if that has something to do with it.
Just DIY'd the first oil change on my new 2013 Prius at 2100 miles. When I first started the engine after the oil change, it was knocking and sounded a little rough for about 5-10 seconds.
View 19 RepliesI had a toyota prius gen 3 last year where it had an engine knocking sound, where I tried every TSB and changed the spark plugs, spark plug cables, intake manifold, engine knots..... etc., nothing worked except the following video which solved the knocking completely with no return.
View 12 RepliesYesterday, while at the store. I started my 2004 prius and the engine was making some crazy knocking noises. I went to auto zone and pulled the codes. It said random cylinder misfire and misfire on cylinders 2,3, and 4.
View 1 RepliesI took my car for the engine knocking at 34xxx miles to the dealer here in NJ. They mentioned it was the EGR that was clogged, so they replaced it. 2 weeks after that, the same incident happened whenever it wasn't allowed to warm up. This time the dealer diagnosed it with having a hole in piston #1? To make the story short, i received my car 2 days ago with a brand new engine from toyota. I tried to re-create the same issue, and it would not happen. Could this be resolved once and for all.
View 19 RepliesInitially thought that this was related to some water in the tank, since it started when the gas dropped to 1 bar (already put some stuff HEET when put the whole tank, did 60miles so far). ODB throws out multiple cylinder misfire (codes 300, 301, 302, 303 etc). It lasts up to 3 seconds. Sometimes the check engine pops up sometimes it doesn't. there was absolutely no problem under load. does it seem like a fairly common problem ? Intake manifold clogged ?
View 14 RepliesI started my Gen 4 Prius two yesterday and got out to adjust a bolt on the rear license plate and noticed a strange sound as the ICE in high throttle began the warm-up cycle- a sound like water sloshing around in the cat converter (or somewhere upstream?). Other new Gen 4 owners please check this and see if you hear this on startup. It is not regular enough a sound to be engine knocking, but literally like water churning. Not loud enough to hear from anywhere but right near the lower rear of the car. Hear this on new 2016? My Gen 3 never had this sound.
View 2 RepliesSometimes I have to park my car two blocks away in the afternoon, and later in the evening i need to park my car back to the spots in front of my apartment.
EV mode won't be enough to last the two blocks, even at 7 bars. Or sometimes the car won't let me turn on EV mode, even at 7 bars (battery too cold).
So the engine must run if i want to park my car back near my apartment. But the two block distance will not suffice to completely warm up the engine
So the next morning... (20~ Fahrenheit)
My car knocks for a few seconds the next morning the car starts up...
What is the definition of completing the warm up cycle? 120F? My car will turn off the engine after coolant temp reaches 120F (ECO mode).
I have a 2010 Toyota Prius. The other day I was stuck in a traffic jam - under 5 mph for at least 30 minutes.....my engine started knocking/vibrating...once out of the jam, it felt like the engine was "missing"....I took it to the Toyota dealer in town and they changed the spark plugs and cleaned the area...the car runs a little better but I was in a funeral procession yesterday and after about 15 minutes the car was knocking again. What the problem could be? The mileage on the car is 125,000 (I drive a lot!)...
View 3 RepliesThe truck is a 4WD with the 4.8L V8, has 134k problem free miles. While pulling a camper trailer the Service Engine Soon light came on and was blinking. After removing the camper the light went away. Now the light has returned and blinks occasionally. The light is not the larger issue tho. When the engine is cold it is difficult to start and I have to hold the accelerator to the floorboard to keep it running or rather chugging but only on days when ambient temps are below 50ish. As the motor warms it chugs less and eventually smooths out. Once the engine has warmed up it runs as if there is no kind of problem. The service engine light stays on but does not blink. This all began suddenly tho there might have been a problem before but we recently moved to the Chicago area from the Phoenix area. A stop at the local auto parts store for a code read said the fuel pressure sensor is bad tho it seems there is something more than that going on. With a Chicago winter coming this needs repaired!
View 3 RepliesI just made my first payment last friday and today my check engine light is illuminated. I did have one of those awful cold, knocking starts the other day!
