Sonata I45 (LF 2015+) :: Jerking Movements At Highway Speed Acceleration?
My problem is this: if I accelerate quickly (either flooring it or close to it), then once I reach about 55-65mph the car suddenly jerks horribly. Sometimes it's one big jerk, other times it's several small jerking movements. ECO transmission ...
It's not a problem at speeds under 50mph, but it seems once I cross that 50-55mph threshold, I can't put my foot all the way down or I will get the jerking. It will also occur if I'm going say, 60mph and need to quickly get to 75-80mph. The first time this happened, I was accelerating onto a highway and the car jerked so badly that I thought I had gotten rear-ended.
Prius (2004-09) :: Slight Vibration / Stutter Feeling At Low Speed
98k miles and if the car is on a slight incline and your backing up or creeping forward it feels like you are going over a rumble strip. that slight stuttering feeling. no codes have tripped. I've asked the toyota dealership and they don't know what could be the problem. The trans axle fluid was changed at 88k and from what i was told there were no metal shavings in the fluid. it was a little dark but after going 88k miles i assume it would be.

I've been noticing a metal type 'clanking' sound whenever I am gently accelerating up a hill on my 2.4L.
It doesn't happen all the time though. It's not the usual GDI ticking sound. It can be heard when the windows are open but yet I can not tell where the sound is coming from. It doesn't happen enough that I can replicate it so I haven't taken it in for a check. The car drives fine though.
Sounds when going up a hill? Not sure if it's from the engine or from the transmission getting confused trying to change to the right gear. Perhaps the sound is just normal...
Sonata I45 (LF 2015+) :: Grumbling Noise From Engine When Accelerating Uphill
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.
View 11 RepliesFord F-150 (2004-2008) :: Slight Shake At Highway Speed About 90 KPH
So, after putting new tires on my truck about 2 years, I noticed a slight shake when I drove at about 90kph. I let it go for quite some time thinking it was just a balance issue.
Well this weekend I spent 7 hours washing, waxing, and polishing my truck. It was worth. The rims reflect the moonlight now. It's amazing. During this washing, I scrubbed in behind the spokes of the rims. I found a big chunk of mud. Well surprise surprise, my shake at 90kph went away... or so I thought.
I no longer have the shake when driving at 90 or accelerating through 90kph like I used to. Now I have the shake when I let off the gas at 100 and drop to 80kph. It shakes at 95 through 90, and then goes away.
What is causing this? The parking brake is never used, and is showing no signs of engaging while driving. Is this a driveshaft issue?
Sonata I45 (LF 2015+) :: Slight Shaking Of Car When Stopped
I was just wondering if you all experienced a slight vibration of the car when stopped at a stoplight. I experienced a slight shaking of the car when I am at a stoplight especially feel it at the driver seat. I have about 300 miles on the car so far. Not sure if it is just part of the break in period? I only experience it when the car is stopped.

I have been experiencing a slight hesitation when I accelerate from a stop. It almost feels like its going to stall for a brief second then it picks up and accelerates normal until I'm at a complete stop again. I have the 2016 sport with the standard 2.4L. I currently have 2200 miles on it now and when I go in for my initial suggested oil change at 3000 miles ...
View 25 RepliesGTI 337/20th Anniversary :: Slight Whirring Noise When Gently Feathered Gas To Maintain Highway Speed
Middle of May, I went to Boston. On the way there, I started to notice a slight whirring noise that was only present when I gently feathered the gas to maintain highway speed. If I were to apply any more throttle, the noise would go away, and if I were to pull my foot away and allow engine braking, it would also disappear.
So I did my best to finish the trip to and from Boston adjusting my driving to avoid the noise. Once I came home, I researched and thought the noise might have been my wheel bearings (I had just replaced lower control arms, lower ball joints, inner and outer tie rods prior to leaving for Boston). I also had a shop install my upper strut mount bearings and bushings simultaneously with the wheel bearings.
Since then, the problem still continues. It has grown louder, but still occurs under the same situations. I've focused more on it and here are the conditions under which it occurs:
1. Car must be warmed up. Starting it up cold and allowing SAI to run then driving, car is fine, no sounds. Usually takes 20-25 mins of driving to get it to start making noise.
2. Car still only makes the noise when the gas is being feathered (ie barely pressing it enough to give it any sort of throttle. It does also make the noise between shifts when reengaging the gear and applying gas, as the throttle pedal passes the point of throttle off to throttle on.
3. I'm hearing more noise now during engine braking than I had been previously. Could be related?
Sonata I45 (LF 2015+) :: Cabin Vibration At Highway Speeds
So about 5 months ago I started feeling vibrations in my seat and steering wheel. I got my tires road force balanced and it solved the issue. I just got back from a weeks long vacation in Maine. Before I left I had the tires road force balanced again to ensure a smooth ride up. I left some shaking in my seat so I wanted to get it ironed out.
While driving up my seat and the entire cabin shook when I exceeded 70 MPH, it got worse and worse the faster I went. The steering wheel didn't shake at all. I figured the tech balancing the tires did a bad job so I visited the BJ's in Portland. They re-balanced all my tires, I was present when the job was being done and noticed they were all out of balance.
The BJ's tech said it look like the shop that did the balancing over balanced each wheel (too much weight on each wheel). As soon as I hit the highway the same thing happened, shaking above 70MPH. At this point I determined it was probably a bent wheel. I visited a local wheel repair shop, they checked out both my rear wheels, since the steering wheel wasn't shaking I didn't bother checking the front ones.
It turns out both rear wheels are ever so slightly bent, they attempted the straighten out the more bent one. They tech repairing the wheel said he was surprised I even felt anything at all. So I had my hopes up that the problem would be fixed but as soon as I hit the road the same shaking returned. At this point, what's wrong with my car. I'm thinking of buying 4 new wheels, the car came from the factory with low profile 18 inch wheels which have been a curse.
A few more details about my car:
Toyo Proxes 4 Plus - Ultra high performance tires (Maybe contribute to harsh ride?) 20K miles on them
Installed thicker 20mm rear sway bar 6 months ago (But I never had shaking until now)
Installed front tower strut bar 6 months ago.
Total mileage 32K
I have hit lots of pot holes the past 2 winters lost 2 OEM tires and bent 1 wheel last year which was repaired.
Also I can't drive through it, the shaking doesn't stop with more speed it only gets worse. And the back end has started to feel squirrely over bumps.

Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!
View 8 RepliesSonata I45 (LF 2015+) :: Slight Clicking / Rubbing Noise Coming From Steering Wheel Column
I ask this because when on the hwy (60-70mph) you can feel some vibration in your hands. I can let the steering wheel go and it won't move a bit but when hands placed on it you can definitely feel the road, including bumps, and regardless of road conditions. Tires where balanced at 7500mi but it still happens. Regardless of temperature or PSI in the tire.
I thought we had electric/electronic steering and no hydraulics? Maybe unrelated but, when turning in my driveway, very slow, I can hear a slight clicking (maybe rubbing) noise coming from the steering wheel column. Everything else has to be silent to be able to hear it.
Sonata I45 (LF 2015+) :: 2016, Low Speed Solenoid Noise
2016 LTD 7200 miles. Been to the dealer twice for routine service (oil change both times, tire rotation and air filter change as well second time. First and last time they are changing air filters; what a freakin rip off)
So this noise occurs at very low speed (1st or second gear) and very consistently occurs when lightly pressing the throttle and usually occurs when releasing as well. It sounds like a clock tick and in fact sounds very similar to the shift interlock solenoid sound you get when tapping the brake while in park.
Furthermore it doesn't happen from a cold start. Car has to be driven a bit and brought up to normal operating temperature; for example I can't reproduce the noise at all first thing in the morning before heading to work, but can with no problem once I'm at work creeping though the parking garage. So I think this rules out any gear slack or other such mechanical slop that could make noise when load is first applied and then again when released. Also it's not audible with the windows down. Cabin has to be very quiet to notice (again, like that shift interlock solenoid tick).

Sonata NF (2006-10) :: 2009 - Stalling While Driving At Highway Speed
My 2009 sonata started having issues with slight up and down accelerations while cruising and the check engine light would come on Then during start up the engine would accelerate up and down about 1500 rpms. I have taken it to two dealers neither could find anything wrong and said their was no record of an event on the computer. Now the car is stalling while driving, once at highway speed. It has happened three time this week. After coming to a stop, I wait a few minutes and the car starts up like their is nothing wrong. The engine light comes on for a while.
View 9 RepliesSonata I45 (LF 2015+) :: Cruise Control - Transmission Will Downshift To 4th Speed Whenever Go Downhill
The cruise control on my 2013 works as I expected.
However the cruise control on my 2016 Sonata does not.
When driving at highway speeds (65 to 70 mph) in cruise control and the shifter set on "D" (drive) the transmission will down shift to 4th speed whenever I go down hill.
This might be intentional as a way to keep the car from exceeding the set speed, but I have never heard of this and it would seem to place more wear an tear on the transmissions.
Do the down shifting is engineered in or if it is a service problem that I need to have addressed...
Sonata NF (2006-10) :: Occasional Power Steering Loss Right After Slowing Down From Highway Speed
My 2006 Sonata V6 (88k miles) has an occasional power steering loss. It has only been noticed right after slowing down from highway speed. Total loss for a few seconds then comes back. No dash lights or noises, just cant steer - then can. Did all required maint. until 60k then just oil changes by me. Have read other forums about fluid flush, but that was for noise and I don't have any noise. This has happened with and without the Electronic Stability Control turned on. Other than that, runs great. MPG is about 25 or so (wish was 30 or so).
