Prius (Gen 3) :: 2010 Engine Clicking Noise When Accelerating
Jul 24, 2012
I 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.

When 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?

I have a 2007 Azera with a 3.8 engine. It has 16000 miles without any problems. There is a clicking noise coming from the engine compartment when accelerating. The noise only occurs when the engine is cold and seems to be more pronounced when accelerating quickly. I do not hear it when the car is idling.

2003 Chevy suburban, 115K miles, accelerating I hear a squeal/groan/clicking noise coming from right front of engine. Did not happen this winter, started again in spring. Loses power if stay on accelerator. If let off and then reapply, it will momentarily go away. Appears to be only when air conditioning on. Bad AC or just the pulley?

I posted before on this issue and wanted to include a video I just made yesterday.
Noise occurs @ 0:03, 0:12 & 0:42

I was going on a trip and checked the oil before I left, I was about 2 quarts low. It's only been 5,000 miles since my last tune up.
Took it to the dealer today to have a clicking noise and also had them look for oil leaks, (Prius parks on a gravel drive)
Service manager said it's probably burning oil.
I'd really like to do a compression test to determine if I have worn rings or bad oil valve seals. Latter would make me feel better.

So lately I've been hearing what sounds like a slight lifter knock that develops at 1500 rpm to 2700 (I have ultragauge) when accelerating or maintain speed, and it only appears when the engine is at operating temp and disappears when rpm is below 1500 rpm and above 2500 rpm my oil is running at 3900 miles using Toyota synt 0W-20 and it looks pretty clean and at high mark of the dip stick.

So i'm only a week and a half into owning my Elantra, 800km on it and today when i started the engine i noticed a clicking/rattling sound, like the noise when someone sticks a piece of paper into a fan. Anyway it's quite minimal and you could hear it louder when you accelerate. I never noticed it before, even when i test drove the vehicle.

My girlfriend owns a 2012 Elantra limited with approximately 20k miles on it. Two weeks ago she asked me to listen to it, because it was making a clicking noise. We've had sub zero temps here in Wisconsin, so I assumed it was the normal cold start up noise.
I quickly realized it was something much worse. It sounded like the timing chain was making noise. We took it to the dealer ASAP. They tore into it and said that the timing chain tensioner had failed. Now ten days later they called and notified us that the engine was still making noise after the tensioner had been replaced and the oil pan is full of metal shavings. It sounds like they will be replacing the engine.

Just recently my Prius has been making a clicking noise when turning right and braking at the same time. It only happens during a right while braking and not while stopping straight or left. I only have 27K miles on it. I'm not due for an oil change for a couple thousand miles and was going to wait until then to mention it to the dealer.

I have noticed in certain circumstances that the engine seems to be in a resonance where it is shaking noticeably and getting worse not better. It happens in two situations.
One is after gliding and slowing to make a turn (with the engine off). As I am exiting the turn and hit the gas the car shakes a lot for about a second or two, then smooths out.

I've noticed that when accelerating from a stop and turning onto an adjacent street to the left or right, there seems to be stuttering or shaking coming from the engine. I'm usually in ECO and only 1/3 of the way into the "engine half" zone on the HSI. It's not consistent but has become a bit of an annoyance.

I've been noticing a clicking noise when the rx comes to a complete stop and accelerating from a stop. Sounds like a sticky caliper but just wondering if it could be some other suspension issue ... RX350 ...

I recently purchased a 2013 elantra.
I have noticed that there is engine vibration and noise felt in car and pedal when accelerating at around 2500-3000 rpm's before it shifts. Is this normal behavior? It just does not seem as smooth as it should be. I have only put about 600 miles on the car.
It has been very cold, but it does not go away after warming up.

I hear this clicking/ticking noise on the driver side front wheel or somewhere there whenever i reached 40mph and up. Car drives straight and no weird anything, just the noise.

I bought a CPO 2010 Camry LE (2.5 4 cyl, 6 sp auto) a few months ago. The car had around 34K miles when I got it, and ever since then, it has had a high pitched whining noise when accelerating or revving the engine in park. It is noticeable from around 2500RPM up, and seems to be a little louder when the engine is cold.
I have left it at the dealer twice, and both times they have come back and said it is normal. I can't believe this, because I have owned many cars over the years, most of them being fairly dilapidated, yet most of them haven't had a noise like this. I think I have read a comment online somewhere that an issue like this was found due to a bad power steering pump .

I have a 2008 Prius and recently hit the 85K mark. A couple of weeks ago, about a week after my most recent oil change, I started noticing a noise when I accelerate. It's kind of a wah-wah-wah-wah or wuh-wuh-wuh-wuh noise that gets faster the faster I'm going. It's not terribly loud - I can't hear it if the windows are open or if the volume on my radio is cranked up.
It disappears when I stop accelerating or sharply reduce my acceleration. At about 40-50 mph, the noise goes away. I'm not sure if this is because road noise blocks it out, or it's so fast-paced that it just becomes one constant noise.
Today for the first time since this all started, I also noticed that unless I'm not accelerating at all, I have poor gas mileage (like under 25 mpg). This happened once before and went away the next day so it might be unrelated.
Can I wait until my 90K service to have this checked out? Should I visit my mechanic now? Do you think this is a timing chain issue? What am I looking at?

So after doing some troubleshooting and researching in trying to find out on my 87K 2008 Prius Std "Noise in the engine while accelerating", "Approximately 10% reduction in fuel efficiency, due to lack of power from engine" & "Glide seems to be degrading over time", here is what I have observed.
1) When I push the gas when the car is parked the engine does not seem to rev in a stream, it goes up for about 3 seconds then goes down for 1 second, then again goes up and then down and this keeps happening until the gas pedal is kept press. In conventional cars the rev should be streaming continuously and proportionately to the pressure applied on gas pedal. This almost seems like a misfire, but from the drivers seat I do not hear any blasts, I have never tried this before so I don't know if Prius's are suppose to be like this. Also no Alarms on the MFD.
2) After using the 5.25 oz fuel injector cleaner in back to back half tanks I saw the engine regaining power and hence bettering the fuel efficiency. Does that mean I should get a Fuel Injector cleaning done by Toyota?

I have had my car a whopping 3 weeks and I noticed a weird click. Was driving my car today between two concrete walls with the windows down, and accelerated in 3rd into a little bit of boost and noticed a click-click-click rapidly as I accelerated. As I let off the gas, it slowed down and stopped. The car is stock, and it doesn't sound like any type of spooling from the turbo itself.
Only happens under acceleration past 2.6K (What feels like boost - No Gauge yet)
