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.

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 RepliesNissan :: Screeching Sound For About 15 To 30 Seconds After Starting
My 97 Nissan pick up, 2.4L I4, 5 speed 182k miles has developed a screeching sound for about 15 to 30 seconds after starting. It sounds like a loose or slipping belt. I have replaced all three belts and the tension is right.
I pulled all the belts again and put them back on one at a time and determined that the belt for the water pump and alternator is the source. I checked all pulleys and components and cannot find anything with abnormal drag or roughness or noise.
I though maybe that I might have put too much tension on the alternator belt and maybe put to much side load on the alternator bearing so I loosened it slightly and that just made the screeching last longer. I also noticed that the duration of the screeching is extended when there is a load on the alternator, such as the blower motor or the headlights.
Once the screeching stops, it does not come back even with sudden changes in rpm or changes in load, i.e. blower motor or headlights, however, every time the compressor kicks on, there is a chirp. Before I replaced all the belts, the compressor belt was slipping on occasion and every time the compressor kicked on, it would screech for a few seconds, but its not AC weather right now.
I pulled off the alternator today and took it up to be tested to see if it would screech on the test set, not a peep and passed all tests. BTW, I am not having any issues with charging or starting, the battery is good. I did notice a wire bundle that runs under the air cleaner has abraded and one wire is bare, I'll address that tomorrow. I don't see any evidence of shorts in the bundle, all the abrasion is on one side and only one wire exposed, and it only touched plastic as far as I can tell.
Also, I cannot visually detect the slipping, the belt and the alternator appear to be moving smoothly, same with water pump, but its hard to tell because everything is spinning so fast. also, it is not bad if you just do a restart after driving, is will only screech for a second or two, but if it cools down, than it back to the 15 to 30 seconds of screeching, and its LOUD.
Passat (B5) :: Ominous Screeching Sound For About 3 Seconds When Starting Out
Yesterday I started the car, backed out of the driveway, and as I was starting out in first I heard a screech-like sound for about 3 seconds, then it disappeared. It sounded like a belt or pulley might be slipping. There was no smell and the car ran fine and quiet after that.
I'm beginning to get worried with this car. I have a check engine light on, the suspension is clanking again, and I saw an abs light for about 5 minutes one day a couple of months ago. My wife claims to have heard a grinding sound in second, but I haven't heard it yet. I'm at 6 years, 3 months of ownership, with 85 K on the ODO. It seems like these cars are designed to drive worry free for about 80K. After that, things just start falling apart. I really wanted to make it past 100K, but now I'm not so sure...
Prius (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...." .
Honda - Accord :: 1992 - Screeching Noise Comes For Several Seconds
I had major tune up on my vehicle. First I had the timing belt and accessory belts replaced including of course the water pump. I also had the shocks replaced. My question is now everytime I start the car I would hear a screeching noise for several seconds and also when I engaged the a/c. Furthermore, in regards to my shocks when I drive over 60 mph my steering wheel begins to vibrate tremendously.

I have an 07 v6 3.6L (50Kmi) that makes screeching sound upon startup for 15-30 seconds. Not belt/pulley noise, more like valve lifters without oil noise. Trying to decide whether to go to the dealer before the power train warranty expires or to leave it alone.
View 1 RepliesPrius (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.

The 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 RepliesLexus GX 2004-09 :: Loud Screeching When Starting The Engine
I've been hearing a loud screech on occasion when starting the engine. For a while, I was not able to isolate it and thought it may have been the HVAC fan bearing or something, because it sounded internal. It hasn't happened overtime, but often enough. The other day, the door was open when I hit the starter and it's loud as H3!!. It'd without a doubt external and seems to taper of rather quickly after the engine starts. At this time, I'm pretty sure it's the starter, but may be belt tensioner.

Passat (B5) :: 2001 - Car Starting In EPC Mode After Like 8 Seconds On The Ignition
I have a 1.8T 2001.5 Passat, Tiptronic with an Upsolute chip. I recently had the turbo replaced (under warranty for the same stock one). After the turbo reinstall, the car did this after driving it a while: I ran it hard and spooled up the turbo good a few times, and then parked the car. I would wait 45-60 minutes. When I tried to start the car it wouldn't start for like 8 seconds on the ignition, and then it would start but in EPC mode!
The first time this happened I panicked, drove it home (just to make sure I got home.) I then tried again and it started fine and no more EPC. Also, if I wait much longer like 3 or 4 hours, it never happens. Since the first time, this has happened like 10 times or more. But now, I just turn it off right after it starts in EPC, turn it again, and it works fine.
The first time it happened I got some kind of codes, but I didn't save them and cleared them. I figured since it happened again, I would get the codes again, but they're not there. I took it to the dealer, and of course, they can't duplicate it. The codes where like speed implausible or not there or something but I can't remember now.
The master mechanic told me to vapor lock was not possible because I had no carb, but I seem to remember that my '83 fuel injects 280ZX turbo had a special cooler fan to cool down the injectors in the event of vapor lock after the car shut down so I'm pretty sure this is possible with injectors. I mean, the explanation for that fan was so that if the remaining fuel in the injectors would get so hot after car shut down that it would vaporize the fuel and the pressure would lock up the injectors.
Prius (2001-03) :: Engine Starts And Runs For A Few Seconds Then Bucks And Stalls
My 2001 Prius (230,000 miles) is unusable. I can clear the codes. The engine will start up fine. After a few seconds it starts bucking and jerking as if the engine is trying to engage something that won't turn and finally stalls. It is similar to a manual transmission car's action if you fail to push the clutch in when you stop the car. What the engine is trying to engage? I don't have any scanner to read the codes.

Pretty soon this thing's gonna have ALL new parts and STILL running rough! The Jeep has about 40K on a Jasper motor, 175K on everything else. I was experiencing starting issues (crank for 20-30 seconds), and noticed a P0171 code on my odometer (O2 sensor?) so off to my mechanic. He replaced two O2 sensors, no change. New code read MAP sensor, replaced, no change.
Finally, changed Fuel Pump in tank (Fuel filter was changed 2 months ago), still no change. I tried starting it tonight by turning the key 5-10 sec. to prime gas, started but still rough at idle. Runs strong above idle 1500-2000RPM. Mechanic can't check fuel pressure at rails? for some reason. My next thoughts were spark plugs and vacuum lines...
Elantra XD (2001-06) :: Screeching Noise When Driving - Gas Mileage Reduction
My '03 Elantra has started making a screeching sound when I drive it. At first, I thought it was due to the cold weather, but it has occurred even on warmer days. It makes the noise intermittently, sometimes not at all. Sometimes when I turn sharply or back up, or when I just drive it. What is odd is that I had the belt changed last spring, and I inspected it and it does not seem ripped or stressed at all.
Not sure if this is related, but I noticed that my gas mileage has been greatly reduced. Last week I filled up a full tank and drove about 6 miles. When I filled up, the needle was above F. Later when I got home, the needle was just a few ticks below full. Within two days, I was at half, only driving a combined total of about 16 or so miles, city driving. This car has always had great gas mileage, even with snow tires. My mileage is 56,815, and I've checked for gas leaks and found none. My RPM's don't rise, my engine does not overheat, though I did find some weird oil on the black hood on the engine last week when I checked the belt. I checked the oil levels and they were good.
I'm taking this in tomorrow, and am scared that this is the end of this car. What may be the cause of the screeching and loss of fuel efficiency?
Starting - Chevrolet - Tahoe :: 2001 - Clicking Noise Right Before When Engine Trying To Catch
I have a 2001 Chevy Tahoe, and for the past couple of years, I have been having an incredibly frustrating issue with my car. When I go to turn the key, it sounds as if it is about to turn on (ie the engine is about to turn over and it sounds normal) then right before it catches, it will start clicking, the noise sounds like the battery is dead. When it first started happening, I called AAA, however by the time they reached me, the car had started again. Now when it occurs, I wait 10-15 minutes and it will start- every time. I have had it in to 4-5 different car repair shops, however no one can seem to figure out what it is. I have had the battery replaced, and several other things altered, etc, however nothing seems to fix the problem. I am not sure where to go from here, I was informed to check the fuel pump and/or filter yesterday- it happened twice on me yesterday as well.
View 3 RepliesPrius (2010-12) :: Cyclical Engine Noise Every One To Two Seconds
I have a new 2010 Prius so am getting used to a different driving experience. One thing I have noticed is that between 55-65 miles per hour I hear a cyclical engine noise every one to two seconds. It is a hum followed by another hum. The noise is not constant but has a one or two second delay between hums. But this cycle is constant between these two speeds. Is this a normal engine sound? If so, why do I notice it only between about 55-65 miles per hour? A technician at a Toyota dealership told me that the 2010 Prius has 26 onboard computers to detect any problems. He said that if there was an issue a red triangle would appear on the display to alert me to any type of problem. I am about to make a 3,000 mile round trip in the Prius and need to know if this cyclical engine noise is cause for concern or just a normal part of the electric/gas engines operation.
