Lexus GX 2010+ :: Engine Sound When Accelerating Or Going Uphill
Jan 2, 2014
I purchased my 2014 GX a couple of months ago and already logged in about 2K. The car has been great so far. The only thing that I'm not so used to, is a strange feeling when accelerating or going uphill (even slightly) - I can feel the engine roar(?) through the steering wheel - I can't really describe it well - it's not a vibration per se, but more like you feel the engine working harder than usual through the slight vibration of the steering wheel. This is my first V8 car - I used to have a V6 Acura MDX before, and never felt that. There is a good chance this is normal for a V8 based truck, but I wanted to get others' input.

I am hearing a quiet knock from my 2013 accent, especially when accelerating or going uphill on low RPM. I am getting about 34 MPG after burning a tank of regular gas (87 octane rating) on my commute which is about 2/3rds 50-70mph freeway and 1/3rd stop and go traffic. I usually get more MPG than what the EPA rating is, so that number seems a little bit low to me, but I just got the car used, so I don't know what's "Normal" for it. Idle is pretty quiet though.
I would give a video where you can hear it, but honestly it is pretty hard to hear from inside the car. I generally have to be near a wall with the windows down or something to be able to hear it clearly.
2012 Accent 1.6L GDI Engine Rattle/Knock/Buzz
Also, there are no lights showing on the dashboard besides the ECO light since I have been running the car in that mode. Is it possible that there could be codes that might give more information even though nothing is showing on the dashboard?

I have a 2015 Sonata SE 2.4L with 15k miles. Sometimes when accelerating, and almost always when accelerating uphill, the vehicle makes a noise that I can best describe as sounding like a grumbling or rattle from the engine. It almost has a "diesel engine" sound to it. I have noticed this going back to when the vehicle was brand new, but I have recently noticed it more.

We've got a 2012 Hyundai Accent GDI. I've been hearing the rattle "ping" when the engine is under load (accelerating hard or uphill). I've read that this is typical for these engines.
I took it to our local Hyundai dealership since it's still under the 60,000 mile warranty. They updated the computer settings and I put in a fuel additive to clean up deposits. They also told me to buy name brand gas from here on out (Exxon, Shell, Mobil) as these engines don't handle cheap gas well.
Now that I've given you enough of a backstory, here are my questions:
- For those that have experienced the rattle "ping", what did you find fixed the problem?
- Any tips or things to look out for when cleaning the throttle body etc?

I just purchased my Elantra MD for just 2 years. Yesterday I went uphill (not steep) then decide to change from auto to manual, then I move the stick, it shows I am currently in gear 5 so i downshift to 4. After a few second the was a 'jerking' with 'thump' sound from the bay. My rpm came down slowly, i pushed the pedal but the rpm wont go up. it just glide. Shut down and up the engine changed nothing. When i try put reverse gear, it reversed fast as if i pushed the pedal, but i am not.

Going up hills, I noted the eco lite remained lit during the downshift mandated by cruise control to maintain preset speed. However, during ascent with cruise control off, and slight decrease speed (no downshift) the eco light will go off. Kinda counter intuitive, that slowing down during ascent would be less economical than maintaining set speed during climb.

I bought my RX350 last month and sometimes I notice a strange buzzing sound coming from the car while the engine is off. This noise can come at anytime and usually hours after I have turned off my car. It's difficult to isolate where it's coming from and can last just a few minutes.

Finally got the Tech to acknowledge the Humming/Groaning from the Engine as I sat behind the wheel at my 5000 mile service visit. His response was that the sound we were hearing ( at start-up) was "NORMAL"
The RX drives and sounds fine after that mileage, but many times my destination is less, and I feel like I am driving a reject.This has persisted since new, @ frigid and high temps; as we approach 7500 miles.
Engine sound varies in pitch when acceleration increases the RPM's ?

The road my house is on is a steep hill. In the morning when I first start the car I have two choices. I can jump right on the hill and start climbing. Or I can drive down the hill and do a little quarter mile loop before I start climbing the steep hill. Which approach is best? Or is there a better way to handle this?

I am getting a strange chirping sound from the engine (during idle) on my 7 month old RX350..Is this pretty common ... experienced a strange howling engine sound when you accelerate the car( E.g. when you are going at 30 mph and want to speed to 60 mph), I can hear this when I turn off all the noise (radio) and drive on a quiet street...

2010 Hyundai Accent GLS (automatic)
Just noticed the last few days that my car has developed a shake when accelerating, but stops after a certain speed. It isn't bad yet, but when I started going up a hill today it was significantly worse. The entire car started shaking, but stop after the car leveled out.
I just put in a new front left and right axle two weeks ago, would that have caused anything ?

Just got a 2012 Lexus RX 350, but find out that the engine sound is quite "noisy" in the lower gear or when pushing the pedal. Is this just my car, or is common?

I have a 2001 Ford Taurus with 103,000 miles. It shudders when I accelerate; sometimes one, two or three shakes. This usually occurs around 35-40 mph while I am going uphill (never while going downhill). I always use overdrive, but I tried it in drive and also felt it then.

My 1999 GMC Suburban just started "catching" when accelerating uphill and going 50+ mph. Does not occur any other time.

This has happened five times within the past couple of months. I have a 2004 Chevy Malibu Maxx LT. In all cases, I was accelerating while going uphill. I am in Chicago so by uphill, think expressway ramp. The Charging System Light and warning bell come on for about a second and then shuts off. When I get home, I check the battery. In all cases, it is fully charged. The battery is six months old. What could be causing this?

I have a 2004 Hyundai Elantra with 130000+ mi on it. The current engine has 96000+ mi; the original was replaced because the previous owner allowed it to overheat, blew a gasket, and apparently warped the engine itself.
I have owned this car for about 6 weeks now. The car was driven roughly 160 mi from where it was purchased to my residence; no trouble on that trip. However, within the first few weeks of owning it, the car started making a squealing noise when I turned the steering wheel. I took the car to a mechanic and had the belts adjusted. This eliminated the squealing, but I was also told that the CV boot needed to be replaced (they asked if I had been hearing a clicking noise when turning, which I had but had thought nothing of), so I also had that repair done. Problem solved. Car seemed to be running fine.
Okay, on to the current problem. Something else I had started to notice, before I had the belts adjusted, was that it seemed to hesitate a little when going up hills, and sometimes when accelerating. It was a small thing, and I attributed it to my driving style (which probably isn't the best) and the fact that my area is very hilly and the car might be having a harder time with that. Well, this problem has gotten worse; I can definitely feel the car jerking, especially when accelerating (very noticeable when going uphill). The problem also seems to be worse at lower speeds, but I'm not entirely sure that I've nailed that down.
One thing I noticed is that it seemed to become much more noticeable after the last time I gassed up the car. It seems like it's getting worse as the fuel is used up, but that's probably just a consequence of using up fuel as I drive and I'm just looking for connections where there aren't any.

i own a 2005 f150 supercrew fx4. Today as I was attempting to go out of town I was accelerating up hill and heard a noise, sounded like air coming through a window seal or scratching, which is not the problem. The noise only came on when i increased the acceleration, there is no power loss, the truck still accelerated properly and had good power, just that the noise came on. so i returned home only to hear the problem on flat land also, when pressing the gas to accelerate. The truck seems to idle fine and have no problem with low acceleration.

I have a high mileage 2002 SC430.
I have noticed that when I start the engine on a cold morning and start driving right away I hear a distinct "cracking" sound from behind the air vents (dash area) when accelerating. This only occurs when the engine is cold and when I am accelerating, this does not occur when the car is parked (I have not tried revving the engine when the car is parked, since it doesn't seem like a good idea).
A a side note, I do typically move the temperature setting to the max of 85 degrees on cold mornings, but the cracking sound often comes up 5-10 minutes after I change the temperature setting. I'm not sure if this has anything to do with it.

So, lately I've noticed a slight fluttering sound in my '08 GS460 when accelerating on the freeway or up a slight incline. It'll kick in around 2,000-4,000 RPM, and it almost sounds like it's coming from right underneath the center console. I did have an exhaust system installed, then uninstalled, so maybe it's something the shop did, but can't be positive whether or not it was there before (always drive with my music on pretty loud).
