On my 2010 Prius ll when the engine kicks in, is it normal for the engine to sound noisy, almost like a diesel. It's embarrassing because the car is noted for bring quiet. Is it not? It was like that when I got it, and I took it back and they checked it out, but apparently they thought it was ok. I'm thinking of taking it back again. Just a little over 4000 miles on it.

View 14 RepliesThere is a chirping sound coming from the engine of my 2010 Prius. It sounds like a really fast bird chirping and my guess is its probably the serpentine belt. It is there as soon as I start car and the engine is running. 80k miles.
View 7 RepliesAt first it was leaking coolant very slowly,then making the rattling engine noise at low rpm then a part flew off while on the highway gushing out oil. Time for a new used engine. Planning on diy if all else fails off the junker. 230,000 miles on odo.
View 19 RepliesI bought a used Certified Prius with 49k miles on it. I noticed when accelerating (and the display shows that I am using the ICE but not so much that it shoots up into the "Power" portion on the far right) that the there is a clicking noise coming from the front passenger side of the car.
It sounds very much like this:
I don't hear it when only the electric motor is running, and I don't hear it when I really punch it and the power meter is completely filled up. Its more when the power meter is in the middle of the display and the ICE kicks in and I am slowly accelerating.
My 2010 Prius has been making an odd noise intermittently while accelerating. I haven't been able to reproduce it for the mechanics (of course). The best description I have for the noise is this. It sounds like the click/rattle sound a car makes when it is stalling. Just sped up. This can happen at any time I accelerate (even at highway speeds) but it usually happens just after I start moving from a stop. When it occurs it feels like there is a drop in engine power and I either have to take my foot off the accelerator, or push down harder and power through.
View 10 RepliesTwice in the last month, my 2010 Prius has made this incredibly loud noise when the engine first started up. The noise continues for a minute or two, and then stops. The car then runs as normal. I brought the car to my dealer, who after a brief looking-over could find no reason for it. I shot a video of the car making the sound the 2nd time it happened and brought it to the dealership with me to play for the mechanic. No one who heard it there ever heard anything like it before.
It has been really cold here this winter, so "cold oil" was once thought, but was dismissed as unlikely. The car gets 0-20 oil.
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.
View 4 RepliesWe're having problem with our Prius where car suddenly started to make weird clunking noise from the engine (28k miles, 2011 Prius). Car sounds unsafe to drive around, so I left it parked in the drive way. I did check engine oil level and it was at F level.
View 4 RepliesI had my Prius for almost 4 years and I'm used to all the hybrid noises: brake pump after opening the door, emission control pump hours after driving, high pitched inverter noise in EV, etc. This is different. Very faint and I only noticed it because I opened the hood right after driving. The car was completely off, but there was some small electric motor activated somewhere inside the engine. Is this electric coolant pump?
View 4 RepliesMy dad has a 2010 prius IV. He told me the other day when he backed out of the driveway and put it in drive he experienced a clanking noise coming from the engine. He said it sounded like metal rattling around. It lasted about 30 sec. then went away. What this may be?? It hasn't happened since.
View 7 RepliesThe noise seems routine. It happens when you get close to the car and open your door. I guess the car is anticipating that you will start the car soon and under the hood, some subtle mechanical noises occur. Just wondering what that noise is?
View 3 RepliesWhen the battery power is low, the engine will kick in and then there is a loud "exhaust" sound. Are those really sound from the exhaust or some other fan?
View 5 RepliesMy 2010 Prius V just past the 24000km mark. I have a buzzing noise coming from the engine bay during startup. It happens when the interior fan is on. You can hear it clearly after you start the car, during the silence of the "boot up", before the ICE kicks in. I can't be sure if it continues to buzz after that because the sound of the ICE drowns it out. However, If I shut off the fan during the boot up, the buzz disappears. Finally, if I leave the fan off and start the car, there is no buzz.
During a recent oil change, a hybrid technician claims that this is normal. It used to happen infrequently but now it is consistent, so if it was normal, I should have heard it when the car was new.
I have a 2013 Prius II with 35,000 miles we bought certified used from a dealer 1 year ago. When I turn the AC on, there is sometimes a louder than normal noise from the front right of the engine compartment area. Not right near the surface - seems to be coming from a little deeper in the engine compartment. If it is present, it starts when AC is turned on and stops a half second after the AC is turned off. Can't get it to repeat for dealer service tech yet (of course). I recorded the sound and played it for the tech who told me to check pink coolant levels in both reservoirs and then bring in to dealer. Thought it could be a dry or malfunctioning pump of some kind? Today I smelled a slight burning smell when the AC was turned on. No check engine light, AC seems to be working fine. My wife thinks the noise may have also been there when the heat was turned on but I cannot verify.
View 20 RepliesWhen I accelerate, particularly between the 50-60 mph range, the engine makes a very subtle, yet definite clicking noise. Mentioned this to the dealer - the car is still under warranty - and of course, they can't replicate the sound..is this common?
View 19 RepliesMy wife bought a new 2010 Prius Hybrid. It has consistently achieved 51+ miles per gallon. She bought it in June-2010 and at the 7000 mile mark (October?) called me concerned about a noise it was making under the hood. She described it as akin to the noise a playing card made when as a child you fastened it to the spokes of a bicycle. Chattering? It lasted 15-30 seconds and went away, before engaging in reverse or forward. A trip to the dealership was fruitless, an "intermittent episode" the diagnosis.
Now, nothing since until today. Same noise again, 12,000 mile mark, goes away in same timeframe, in park. Only today, through the course of several errands, her dash MPG indicator reads 39 MPG. She is waiting as we speak in the dealer lobby as they plug into the computer hunting for fault codes, etc. Having issues, especially an indicated dropoff in MPG seemingly in conjunction with such a noise?
I bought a new 2013 Toyota Prius Three. It has 23K mile on it now. I have noticed a weird noise with vibration from engine when I start the car for the first time in the morning. The first 10 or 15 seconds after it is on, there is no problem as soon as the engine wants to turn on (engage) I hear the noise. There is no engine light or triangle alarm on. What is going on?
View 7 RepliesSo my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.
When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.
What can the issue be? It was very cold and snowing.
I got in the car today and started it... I was waiting a few seconds for someone to get in the car (it was in the garage) and as soon as the engine kicked on there was a very very large long rattle noise i immediately turned the car off. Waited again and turned it on same noise.. the only thing I found was a cover under the car towards the front was really loose. ( I haven't hit bottom or anything while driving) but I did have the lighted door sills just installed the other day. But it never made that noise..
btw i have 1100 miles on it..I looked under it and is the black dust protector thing supposed to be loose like if I push on it I can make it rattle..
Slightly shaking engine and rattling noise on acceleration,it happens when the car is hot and especially when the battery level is very low ,I guess is when as more load . If I accelerate and keep it steady at 20mph I can feel a constant vibration but goes away once accelerating more....like if you're driving on a rippled surface ....that is only when engine is on , doesn't happen on electric only.
The noise it sound like a tapping coming from the engine when slowly accelerating from 0 that goes away as soon I give more gas ,is annoying wile in the traffic.? Can the sparks plugs be the problem?they been changed 120k ago.....,I cleaned the egv pipe but problem still there. Like I said is only when the engine is up to running temperature.
