It was -35 degrees Celsius (-31 Fahrenheit) this morning. My Prius v was parked in the driveway. When I started my car the engine produced a grinding sound. The sound lasted between 30 seconds to a minute, then it went away. I was able to capture this in a video:
I have an inclined driveway, I'm not sure if this matters or not.
My car is usually garage-kept. Last week, I left it in an outdoor parking lot at the airport for 5 days, with temps ranging from 5 to 20 degrees. When I returned and turned it on, it responded with a very loud and visible shudder that lasted about 20 seconds. It gradually diminished, and then was fine. I've been driving it normally for two days, with no more symptoms. But this morning, turning the car on in the garage, it gave me the shudder again, this time for only about 5 seconds.
View 15 RepliesNoticing a somewhat regular sort of light tapping noise from Subaru CVT Outback, when slowing to stop or starting out?
Some days it's noticeable only for about a second after the clunk from shifting, often you can hear it a bit longer.
You can hear it best at about 1 min, and last 40 seconds of this short trip audio-clip.
I have a 2007 GS350 AWD with about 110,000 miles right now. For almost the last year or so it has been burning off some oil. By the time its up for an oil change, it occasionally gives me the engine oil low light. It stays on between a few seconds to a minute and then turns off.
I've been telling this to the local Lexus dealership where i've had all my maintenance done, and they eventually did an oil consumption test. They said it was losing about 1.5 liters after 3,000 miles. They say that is within spec.
This issue came up several times while i was still in my 100,000 mile warranty, but they wouldn't do anything as it was in spec. I don't see how i should get a low engine light warning every 3-4k miles and have been pushing them to do something and cover under warranty since it has been documented as an issue before the warranty ran out. Lexus corporate asked for a compression test (which i had to pay for), the results are below:
Cyc#1: 205 dry; 225 wet
Cyc#2: 200 dry; 215 wet
Cyc#3: 190 dry; 215 wet
Cyc#4: 200 dry; 225 wet
Cyc#5: 205 dry; 210 wet
Cyc#6: 190 dry; 220 wet
After Lexus received the results they asked for, they still said: well the oil consumption is in spec so won't do anything.
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.
View 5 RepliesI 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.
View 4 RepliesMy 2006 Prius makes this noise - like a groaning sound for about 5 seconds - when I shutdown the engine. Always happens when I am NOT at the dealership. Generally happens when the engine is hot. What this might be?
View 2 Replies2001 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?
I'm at my place in Florida 1,000 miles from home, and when I started the car in a mall parking lot, there was some grinding metallic noise for a few seconds and I couldn't get it into first or reverse and the clutch pedal was way down. I was able to get going in 2nd and eventually the clutch was back to normal and I could get 1st and R. What happened? Broke some fingers in the pressure plate? Seems to run fine now but have a 1,000 mile ride ahead in the morning.
View 1 RepliesI recently sold me 91 F-250 and got into a 98 F-150. It's a SuperCab 6.5' bed, 4x4 off-road, 3.55 gears, 5.4 v8 auto. I love the truck, but I am having an issue with a noise at startup.
Every time I start the truck it fires right up but it makes a grinding noise AFTER it starts for about 3-5 seconds. I thought the starter wasn't disengaging in time so I replaced it. The starter I took off was fairly new. It's teeth had just a little wear and the flywheel had no visible wear. I put in the new starter and there was no change at all.
I also changed the oil and filter using Motorcraft 5w-30 oil and a Motorcraft filter. I also started it without the serpentine belt to rule out a pulley bearing. What the noise could be? The truck runs absolutely excellent, by the way.
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...." .
Unlike the full-size Prius I used to have, the c seems to have a speaker somewhere under the hood which makes a buzzing/grinding noise when the car is powered by battery rather than by the engine. Is there a relatively simple way to disable this? I miss 'stealth mode' actually being stealthy. Possible to disable the EV mode 'growl'?
View 4 Replies04 with 200k miles, car started stuttering like out of gas, when stopped there was a grinding noise from engine. Took to dealer on trailer, when it was taken to the mechanic all problems went away. Changed oil looking for metal chips, none. Did computer upgrade which was the only code on the check engine light.
Drove car for two days on short trips, four or five times 20 to 30 miles. Ran great. At around 40 miles on next day same problem. No lights or codes of any type. Carried to dealer again, they said they were not sure if it is the engine, transmission, or something in between. I was told they would have to take it apart to find out and the least amount it would cost is $5,000.
The grinding occurs when the engine is running only. when revved up it is louder, at idle the noise changes while sitting in park, louder quieter etc. when driving on electric, sounds perfect. (no sound at all)
I have the po411 code, not sure which problem it is but when I first start the car it sounds awful like almost a grinding or rattling noise then stops after a few seconds.
View 3 Replies2004 Prius with 109,000 miles. It's been in an accident before (and you can tell, the front right fender is a bit misaligned and the doors have a paint covering abrasions).
However, the car is making a ticking noise every minutes or so. The sound is originating in the Hybrid Synergy Drive converter inverter box and about every minute for about 5 or 7 seconds or so there will be a ticking or clicking noise. This happens when the car is idling, driving, and even a minute or two after car was shut off. The mechanic next door to the dealer didn't know what it is and the dealer is giving me a 30 day. What could this clicking be?
I did an earlier post that the engine in our 2006 would make a gurgling sound for up to a minute after the engine was shut off. I received some replies, mostly saying that this noise was normal.
Well, the other day I decided to check the fluid level in the radiator's reservoir & it was low so I filled it and ---- the gurgling noise has stopped.
Could this gurgling just be a warning that the radiator's fluid is a bit low? So far, this filling has worked for us !! I'd bet that this is rarely checked by any dealer during an oil change?
The explorer has been having an issue starting after its warmed up. Starts perfectly fine when its cold. but sometimes when I drive, stop for 1-10 minutes, it takes a long time to get her to start up. Typically 30sec to 1 min of cranking. Doesn't seem to have any idle issues or issues running.
View 2 RepliesWhen I start my Subaru 2001 Outback, it makes an awful sound. Not as much as a screech, but more like a loud grinding, and then it wanes and goes away after about a minute. Then when the car is warm, the sound is all about gone. It's been going on for a few weeks now and wasn't there before.
Listen to the audio file below.
Well, I had a check engine light that lasted only three days then it cleared itself without any intervention. I checked it with a vag-com and I discovered there was an issue with the intake manifold control. I ended up bringing it to the dealer since it is a fairly new passat, and the service department informed me that the Intake Manifold Runner Control needed to be replaced.
Below were the fault codes.

There is a fan noise every 30 seconds in the engine compartment behind the passengers headlight area. Is there a fan motor there? Could it be disconnected without hurting anything? I can't determine if there is a fuse related to this or not.
