Prius (2001-03) :: Engine Knocking For 30 Seconds When First Starting Up
A 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.

2006 Sonata LX. It's only on a cold start up and lasts for about 30-45 seconds tops..and then it goes away. Car has 74k on it. Treated well. Only use synthetic oil and no check engine lights. Last oil change I put 5w 30 in it. I know it says to use 5w 20. Could this be the problem?

From time to time I get this high vibration on start-up of the car. It almost seems like more of the engine noise and vibration is coming through to the cabin. It only lasts about 5 seconds from initial start up and the rpm does not change and stays constant. This only happens maybe once every other week or once a month. What or why this could be happening?
View 6 RepliesPrius (2010-12) :: Engine Knocking For A Few Seconds At Start Up
Sometimes 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).
Golf/GTI VI :: Knocking Noise For A Few Seconds After Starting Up In The Morning?
Sounds like a squirrel knocking on the rear hatch for a few seconds. Is this the fuel pump by any chance??
What i have noticed is that the relay clicking in the CECM is no longer clicking, yet now i hear this knocking in the rear hatch area when i start it up after it sits overnight.

View 10 RepliesPrius (2001-03) :: Subtle Knocking Noise For Few Seconds When Start The Engine
Recently, when I start the engine (cold or even warm starts) I hear a subtle knocking noise that doesn't last too long but a few seconds. I figured that maybe it's because our area may still be using winter mix gasoline... but I'm not sure. Also, there's a rattle underneath the car when the engine switches into generating electricity with MG1.
This only happens after a start-up procedure (cold or warm). It stops when I push the gas pedal down a little bit (while still in park) then it goes into charging again, and by that time, it's stopped. I figured it may be a heat shield on the exhaust. It sounds more up in the front.
Also, when I start the car, the engine starts smoothly but then 1-2 seconds later goes into spinning MG1 which makes the car kinda sound like "vrrrrrrr---VRRRRRRRRrrrrrrrrrr...." .

Prius (2001-03) :: Screeching Noise In Engine Bay Within 15 Seconds Of Starting
2001 Prius. Within 15 seconds of starting the engine, I captured the screeching sound from the engine bay. Noise went away after about 20 seconds. New serpentine belt and new 12v battery installed. Pass dealer 27-point check. Transmission fluid, inverter fluid, high voltage battery were replaced about 18,000 miles ago. Current mileage 174,000.
Noise is not from the serpentine belt. I attached a mp3 file of the sound. "2001 Prius Noise.MP3" ..... Which component is making this noise?
Prius (2004-09) :: Engine Cuts Out After Staying On For A Few Seconds When Starting Up Again
When trying to drive my car out of the garage this weekend, it started backing up and then it stopped. It would also not do anything when I put it in drive. Next, the engine cut out. It would only stay on for a few seconds when starting it up again. It continued to do this. I had the car brought to my local mechanic who specializes in foreign cars. He called me today and said my car will not talk to the computer. He stated it must be the hybrid battery. He told me I need to take it to a Toyota dealer. My question is how to know if this battery is truly out and there is not another problem? I have a 2001 Prius.

I have an '01 Prius, 185,000 miles. A few years ago, it developed an engine (?) knock immediately after starting; disappears after 30 sec. It has gotten progressively louder and now runs very rough during those 30 sec. After that, just hums along.
View 9 RepliesElantra MD (2010-15) :: Pulley Noise That Lasts For About 3 Seconds
I have a 2013 elantra with about 26,000 miles on it. I usually don't use it on weekends and on Monday's it makes a noise that lasts about 3 seconds. I believe the noise comes from a pulley that is not turning.
When this first happened, pulley had a couple of lines where paint peeled off and now the pulley has almost no black paint left. Took the car to dealer, explained how the noise only happens after not using the car for a couple of days, and they have not been able to repeat the problem, they indicate that they can't replace the pulley for this reason and that the wear on the pulley is normal.
What is causing the issue?
Gmc - Jimmy :: 2000 - Sound Of Pulling Tin Can Lasts About 3 Seconds
Every once in a while, I hear a sound coming from under my car, possibly the passenger side, that sounds like I am pulling a tin can around. It only lasts about 3 seconds. Sometimes I'll hear it when sitting at a red light, or accelerating from a complete stop. Then the sound disappears. This doesn't happen all the time, but I do feel like I'm hearing it more often as time is going on.
I did a little research online, and some say it could be a rock under my heat panel, but that seems too easy. I don't have any issues with shifting gears or accelerating.

Sonata NF (2006-10) :: Rattle On Cold Start That Lasts For 5 Seconds
Two months ago I bought a used 2006 Sonata v6 with 54,000 miles. After a few hundred miles I began to hear a rattle on cold start that lasts approx 5 secs. I did my research and saw the TSB concerning the timing chain tensioners. The TSB instructs the dealer to turn the engine off after reaching operating temp then restart after 10 minutes. If there was no noise after the ten minute start then the car is operating normally. My car does not rattle after the 10 minute start up. I just can't see this as a normal characteristic. What could be causing this noise?
View 1 RepliesPassat (B6) :: Mechanical Noise From Fuel Pump Lasts For About 2 Full Seconds
This has happened twice so far, both with around 1/2 tank. After driving for ~25 minutes to work, I will go to shut the car off, and after pushing the key in and pulling it out, there is a mechanical noise from the rear of the car that lasts for about 2 full seconds. Is this the sound of the fuel pump on its way out? Or just an electrical gremlin (no! not in a VW!)?

I have a 2003 Subaru Forester with 240K miles on it. When I start the engine in the morning, there's a squealing noise under the hood that lasts for a few seconds. (Usually goes away as soon as I pop the hood and look at the engine.) I think it's one of three things: AC compressor, alternator, or power steering pump, but I haven't been able to isolate the noise to one of the three. I don't want to wind up replacing all three.
