Prius (2001-03) :: Grinding Noise For 20 - 30 Sec At Cold Startup In The Morning
Nov 12, 2012
My G1 prius (2001) started making a grinding noise when I start it up in the morning. There are no warning lights (yet) and it drives fine, but that noise can't be good -- something will fail shortly. I've searched the internet quite thoroughly and there was one similar problem reported, which ended up being linked to the ABS pump. The noise seems to come from the inverter, or somewhere under the inverter. I took a video of it and posted it here.

I am experiencing a fan noise that precedes the ICE during morning startup. It sounds like a model airplane with a cheap, buzzy propeller. It is not the cabin blower and it comes from the front of the car. It goes for about 10sec and then the ICE fires up, drowning out the fan noise, which I presume fades out. And then I don't hear it again when the ICE shuts off. I also don't hear it at a stop light or subsequent restarts. Seemingly, it only does it after it has sat overnight.
It wasn't always like this. Nothing has changed in my routine. Build date Sep 09. 10000km.

Need to determine the noise before I took the vehicle in to be serviced. I don't know if I would necessarily describe this as grinding...to me it doesn't sound like metal on metal..but it's not normal.
Only happens on a cold startup, and even then it hasn't been 100% of the time...probably 80% of the time though.

I found this thread, Grinding Sound On Statup but not sure it's the same issue. This just started. Vehicle has 150K miles on it.

I start noticing a weird noise upon cold start up. It sounds like something is grinding. First goes starter sound and then engine noise together with this grinding noise. Grinding noise goes away within sec. or so. It is not really loud, but it definitely not engine or starter sound.
It happens only on cold starts when engine is completely cold. If I start engine, let it run for few minutes, shut it down and restart again, it starts without grinding noise. Don't remember if car was doing it from beginning, never turned car while I was outside. Few weeks ago when temperature dropped below freezing point, I turned ignition through passenger door to warm up the engine.
After that I begun listening every start up. Every start up same noise. Every morning and every time after work I hear this noise. No noise if car been driven recently or engine is still warm.
Not my car, but sound is identical : [URL] ......

When starting my car first thing in the morning, for the first few minutes there is a loud roaring seems like. The sound subsides and the car sounds normally after a little bit. The next issue is when I start the car after it is already warm. It starts very strange...It is a little hard to describe. As soon as you hit the starter it just turns over instantly, seems almost prematurely. And when you go to shut the car off, it just seems like it makes a loud noise and the motor abruptly shuts off. I am not too educated with vehicles, and I am just looking for some input. I just purchased this car a week ago with 82,200 miles on it I have never driven a Buick before so these things may be normal.

I have a 2001 Toyota Camry with only 56,000 miles on it and I have noticed that the engine has been very sluggish on start-up first thing in the morning. This happens only when the weather gets cooler and is worst in winter. Warm weather, no problem. After I back out the driveway, I have to step on the accelerator 2-3 times before the car will go forward. The engine sounds like it's straining. After initial start-up, no problem. Now, lately I have begun seeing blue smoke coming from the exhaust . . . again only on initial start-up in the morning.

Its been getting quite cold here lately at night and in the morning when i go to the santa fe it makes a ticking noise for about 2-3 seconds and everything is fine again. I was thinking of dropping a quart of transmission fluid in the crankcase run it for a bit and change the oil?

I have a 2009 Gen III T Spirit. Recently, and I think following the recent reflash, I have been getting an extra noise on cold startup. It is a scratching noise that lasts just a couple of seconds about 4 or 5 seconds after pressing the start button. I have tried to attach a short recording but cannot upload an mp3 file so have made it into a zip file.
I have checked whether it is radio by removing fuses 8 and 28 and have also switched off the heater fan, both without any effect.

Recently I've noticed more that when we first start the hyundai in the morning or after sitting a while and we use the brakes it grinds/ squeals a little and then doesn't after about 2 or 3 miles. Is this something to get checked out or should I spray something on my brakes to lubricate?
My next step that I though of was to get a simple automatic car wash cause it's been a bad winter in Rhode Island and the street shave been flooded with rock salt. I figure that might cause some friction under the pads.

I'm getting a gas smell when I start the car in the morning-especially if its cold. I typically blow the defroster which only makes it worse. It seems to be worse when its colder out and does not happen as the day goes on. My mechanic has checked for leaks-none. I thought it might be an oxygen sensor(?), he does not think so.

I have a 2002 Prius that is running fine except for a loud noise when I started it up---like the one the exha fan in my bathroom makes, but the car runs well and there are no lights or any other indicator that anything is wrong. I am taking it to a local mechanic today, since I don't trust my local dealer. My car has about 95, 000 miles on it.

My Variant (2007, 48K miles) is experiencing a squealing noise during cold morning (below 45F) start ups? AC always off at start up and the noise goes away once the engine is warmed up. I brought it to the dealer last week and after leaving the car over night they told me the noise can't be duplicated which is a total BS. [URL].....................................

My 01 Jetta 2.0 recently started making a grinding sound on start up! had the crank sensor and the starter changed about a month ago and everything was fine but yesterday, for absolutely no reason it would make a horrible grinding sound on start up.Not the typical one where the engine starts and 2 seconds later it screeches (I searched) but while the engine is turning over it grinds. Once it didn't turn over at all just grinding sound. It's not all the time tho either?

I'm experiencing vibration somewhere under the hood during start. I recently replaced the serp. belt and think it could be over-tensioned.
Possible?
Dangerous?
Or just the new belt needs to stretch?

Although the manual is silent on the topic, I can swear that the font seats in my new PriusC warm up on cold mornings. There is no on/off switch for this to happens...

I just bought a 2006 Sonata LX V6 a few days ago and in almost every way it seems like a great car. My '08 GLS V6 which gave me 150k great miles got totaled in November, which really sucks, but I wanted to find another '06-'08 V6. I noticed when I started it for the test drive that the car made a bit of a grinding noise on start up. I didn't think much of it and figured that the warranty from the dealership would cover any problems.(I probably should've checked earlier, but the dealership's warranty only covers cam and lifter noise and engine failure) After I looked into the issue more, I found out that it is a fairly common problem on the early 3.3's with the timing chain tensioners. I'm pretty concerned based on just the nature of the repairs and the cost I've seen for them.
I'm the third owner so the 5 year/60k warranty is expired, but I know there is a TSB out for the issue. I can't find the TSB anywhere but I've heard to have it repaired the car has to make the noise on start, sit 10 minutes, and make the noise again. If it does, the oil needs to be changed and the test repeated again. Since I'm running Hyundai 5W-20 and an OEM filter already, I tried the test on my own. It made the noise on start, sat 10 minutes, and made it again. It is only for a couple seconds, but it's still concerning to me. I guess what I'm trying to ask is if what I've described is covered under the TSB. I really don't wanna have to worry about something like that right now, so my next question is whether the issue I have is detrimental to the motor. My worst fear would be to have the chain jump a cog on the cam gear and slam valves into pistons.

Every now and then I have rattling noise when trying to start on a cold start in the morning. Mainly just sounds like a dry start. Battery is good, oil is full (high mileage Valvoline 5W20). Ive tried 5W-30 and it didn't do anything, just made the mpgs about 1 less.
Ive had the car fixed for the main TSB issue with the starter/camshaft so that is not it, which caused a full on grinding noise.
Everyday commuter car, use 87 chevron gas always, and I just used Lucas gas additive the last two fill ups (used normally every 1k miles) and still getting the noise every now and then in the morning. Are there any better injector cleaners out there?
Should I get the fuel injectors fully 3step cleaned? when talking to the service rep at brake-masters, they stated that I should use 91 premium gas to work with dry starts to burn off extra carbon buildup. Wasn't sure if that was a good idea for a 09 corolla S?
93k miles, new spark plugs last week, oil changes every 3k.

I've noticed recently that on startup I'll hear a minor grinding noise after the engine has kicked over. Seems to happen more when the car is really cold.

I have a problem that my Treg makes a terrible grinding noise when starting in the morning. It sounds almost like a bad bearing or something. It lasts anywhere from 3 to 8 seconds.

When I turn my key the car makes an awful grinding noise and then starts up fine. What is this and should I have it looked at?

What is this metal on metal noise...you hear it the best around the 7-12 second mark...it is especially loud on cold start in the morning when you put the car in "drive" but don't move the car forward. It also is prevalent on hot days when you park the car outside and just start the car. The sound gets louder when you turn on the a/c during the hot day.
