Prius (Gen 3) :: 2010 Engine Clicking Noise When Accelerating
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.
Prius (Gen 3) :: 2010 - Intermittent Engine Noise While 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.

My 2012 Elantra has been nothing but problems. Unfortunately, with me being away from home in the USA, I haven't been able to bring it to my dealership. Lately, I've noticed that the acceleration of my E sounds different with the A/C on. It's more noticeable right when I hit the throttle that the engine engages, and power goes to the wheel. The sound is a deep more drone like sound, and is only there when my A/C is on.

My 2012 Elantra has 16k+ mi. on it and recently I've noticed a noise while accelerating. It typically occurs when first accelerating between 1st and 3rd. The sound itself is hard to describe as I am not a professional so it's hard to find the right words to give an accurate description. It sounds like something rubbing together or perhaps something loose. Any insight into possible causes for strange noises while accelerating on a car this young? It doesn't happen every time, typically when first beginning the drive and occasionally when beginning from a dead stop at a light.

I have about 72k miles on my Highlander, which we purchased certified through a dealer in May. At the time of purchase, we noted an intermittent rattling noise, but didn't think much of it. It has increased in frequency and in volume since that time. I have had it to the dealership four times now to have it fixed. They have replaced the heat shield on the exhaust, tightened my license plates and today replaced my catalytic converter (at no cost to me) Imagine my dismay upon driving home and again hearing the rattle. When they decided the rattle was related to the catalytic converter, they were essentially banging around my car with the handle of a hammer and trying to replicate the rattle...needless to say, I am a little concerned that the techs are unable to determine the root of the problem, much less fix it. It seems to be correlated to some degree with a certain RPM. It sounds as if something is loose somewhere, but that place is a mystery to at least four different techs (all of whom I have driven around so that they could hear the sound and who still cannot identify it).

I have a 2010 Honda Civic with about 67,000 kms. There's a mechanical squealing noise that's started over the last week when I accelerate and turn. It's coming from all 4 wheel areas. It only seems to disappear when I brake. Although if I run/accelerate the car for longer than 5 mins, it disappears as well. Additionally, there's a stretching/groaning noise from the tire area when I reverse. I'm thinking it's probably shock or suspension related.

About a month and a half ago my Elantra while accelerating starting to make a fast ticking noise that was noticeable from usual with the radio and Air off but not terribly loud. The car still seemed to run the same.
So I took the car into the Dealer for my usual oil change and the recall for the automatic transmission and had them check it out. I was expecting nothing major. Turns out the service manager said a control armed failed as well as a piston and the damage was done. The will have to replace the entire top half of the engine at least and check the lower parts while taking it a part. They let me drive off and said to bring it back on Tuesday. Said he will drive to the rental car place and set me up in a rental while they fix it. Estimated to take 4-5 days while further checking into it.
It was noted as a "knock" in the upper part of the engine on the form I was handed after the car was checked out. They also said they would not bother doing an oil change on the car because of this issue. The car has a little over 27K miles on it.
Lexus RX 2010-15 :: Clunk Noise When Braking Or Accelerating To / From A Standstill
I seem to be having a clunk noise coming from my car when braking to a standstill or accelerating from a standstill.
Its totally unpredictable but only happens when braking or accelerating under 10mph.
No noise when going over bumps or turning and its only heard when the windows are down. What it could be?
Prius (2010-12) :: Dies When Accelerating - Fixing P0A94
I'm a longtime reader & today I got a excellent reason to make a post - I was at ~20mph & had just went around a corner & tried to accelerate fairly briskly & the car just dies. Hybrid Failure iirc. I got out of traffic & pulled the codes (BT dongle already installed) Torque shows P0A94 Powertrain. I reset the code & power cycled the car but nothing changed. The traction battery still was showing 5-bars so I moved the vehicle <.1 mile to a safe location. Battery was still at 2-bars when I powered it down.

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.

Just bought a 2010 Prius with 48k miles. I'm noticing what feels like a slight slipping when rapidly accelerating, or that's what I would call it in any other car. It's barely noticeable, and my only concern is if this is the beginning of a transmission issue.
View 19 RepliesElantra MD (2010-15) :: 2013 - Click Noise Mainly Happens When Accelerating From A Dead Stop
My wife and I are new Elantra owners, car is just about to hit 9000 miles on it. I don't know when the noise started happening, but wasn't too long ago. My wife is okay with it, but as for me I find it rather annoying that the car is so new and already making noises. I call it a click but she describes it as a thunk.
Here's the details. The car is an automatic for starters. The noise mainly happens when accelerating from a dead stop. I'll be at a red light and when it turns green, I let the brake go and gently step on the gas and click...there is the noise. Its just a single click, loud enough to annoy me and loud enough that I could hear it when the radio volume is set to 12 or so.
It has also happened mid driving when I release the gas pedal to slow down without using the brakes. Right when I release it, I hear the click...once again a single click.
Now I have taken it to the dealer as a concern because that click wasn't there when I bought the car. They told me it was normal and after waiting 2 hours for a simple oil change to be completed I wasn't ready to argue with them. But I am getting to that point that I'm ready to argue with them, considering the car is so new and still under the warranty.
Prius (2010-12) :: Rough Engine When Accelerating In A Turn And Starting Up
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.
Prius (2010-12) :: Stutter Or Shaking From Engine When Accelerating From A Stop
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.
View 19 RepliesElantra MD (2010-15) :: 2014 - Ticking Noise While Accelerating / Louder At Higher RPMs
I bought a new 2014 Elantra last Monday. Around 100 miles (Wednesday) I noticed it was making a ticking noise when accelerating. The sound gets louder at higher RPMs and goes away when I get off of the accelerator. You can't hear it over the radio but it's embarrassing when my passengers do. It almost sounds like a puff of air escaping or something, similar to a go-kart engine lol.
Anyways, I took it to the dealer Thursday and they drove it and said the noise was normal during the engines break-in period and if it persists after 15k to bring it back and they would see if there was something that needed tightening.
Elantra MD (2010-15) :: Engine Vibration And Noise When Accelerating At Around 2500 - 3000 RPMs
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.
Elantra MD (2010-15) :: Faint Metallic Grinding / Friction / Rotating Noise When Accelerating
My car has developed some intermittent noise but I can't pinpoint the exact source, though it seems to be coming from the front. I hear it in 1st gear when accelerating, and it's more audible if I have my windows down. A faint metallic grinding/friction/rotating noise is how I think I could most accurately describe it. I do have an oil change coming up in the next few weeks and will mention it then.
View 2 RepliesCamry :: 2010 LE - High Pitched Whining Noise When Accelerating Or Revving Engine In Park
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 .
Prius (2010-12) Fuel :: Accelerating Briskly From Stop Compared To Slower Acceleration
I have read that when accelerating from a full stop, it is better to accelerate briskly, but keeping the bar graph in the ECO zone, to cruising speed is better overall for gas mileage compared to accelerating slower and taking more time to reach cruising speed....
I have also heard that it is better to accelerate using the bar graph and making sure it only goes half an inch past the ECO display above it. This way uses less RPM.
Prius (Gen 2) :: Rattle Noise When Accelerating Mid Throttle
My good ole trusty Prius is still running good, change the oil every month (3000-5000 miles) and still drinks oil and a little over half a quart every 1000 miles.. No big deal. Well over the last 20,000 miles I started to notice this off rattle, noise when accelerating mid throttle mostly when up hill. I thought it may have been the timing chain after changing the water pump, spark plugs and using all sorts of fuel additives, but no change.
After time it's only gotten worse, my works buys my fuel (regular 87) but one day I bought my self a tank of super premium, and hey!!! It sounded great, quiet, powerful.
My question is.. Is this because of a worn timing chain making the knock sensor do this, is this because of carbon in the engine? What should I know? I really need to fix this.
