Sonata NF (2006-10) :: Jerking When Accelerating Until The Car Warms Up
This is in regards to my daughters 2009 I4 Sonata. In cold weather, like we are having now in Chicago. After the car is sitting all day or overnight, it will jerk (nice technical term) when accelerating until the car warms up. What is the problem is and how to resolve it?

Over the last couple of days, my 2009 Sonata V6 has developed what I best can describe as a rattling noise near the engine when I am accelerating the vehicle (noise changes based on throttle input). I only hear the noise with the car in drive, if I shift into Neutral or when I am in Park I don't hear the noise when I rev the engine.

View 6 RepliesSonata NF (2006-10) :: Pinging Noise While Accelerating Around 60 Mph
Today I noticed a pinging noise on the highway when accelerating around 60 mph. It certainly doesn't sound like its coming from the lower end and it happened with the engine fully warmed up. I've always changed the oil on time, never has it overheated and it performs very well otherwise, no power losses.
No check engine light is on. In fact, I have heard this same noise on older cars I have owned (Cutlass Ciera) around the same mileage 105000. I am thinking of adding an oil additive, and I have heard that 1 Qt of ATF fluid followed by a drain and refill works well.
I might also do a fuel system purge, BG's has a good machine for that Could this be an EGR issue? Replacing EGR valve? If so was it easy and where is it located. I am hoping I didn't break a valve spring....
Sonata NF (2006-10) :: Noise While Driving And Accelerating Hard
Tonight while driving and accelerating fairly hard we began to hear a noise. The car sat parked for roughly 5 hours and then we began to drive it home (apx. 12-15 miles). About halfway through the drive the power steering went out and the battery light came on. The battery light would turn off and the drivers seatbelt light would come on even while it was buckled. These two lights alternated being on and off 2 times each. We heard something that sounded like a rock got kicked up into a wheel well. After getting the car home with no power steering we noticed the car had begun to run very hot. almost all the way up the gauge.

When accelerating and/or braking, a thumping or knocking noise comes from the rear of the car. I do not believe it's my shocks, as there is no noise when going over bumps, only accelerating and stopping. What may be the cause? Control arms maybe?
View 7 RepliesSonata NF (2006-10) :: Noise And Rattle When Turning And Accelerating At Same Time
Hit a long 4x4 post on the freeway and bent a front rim. Was able to miss most of it but hit it with the right tires. It didn't hit anything under the car that I can tell. Got a new rim and moved the TPMS and tire to the new rim. Back wheel looks ok. Still have a low pressure light. TPMS was lit when I had the bad wheel out of the car but is now out.
Have previously had trouble with another wheel giving a warning when it was only a pound or two low. Checked all the wheels and added a few pounds to each and still have the light.
How do I troubleshoot the TPMS? How long should the batteries last - is this just normal life of the sensors? It's a 2009 model.
Also have some noise and rattles I didn't have before. Not when going straight but when turning and accelerating at the same time. Hoping its just some shields and nothing too serious... I looked and didn't see anything obviously loose so I need to dig into it a bit more.

When I accelerate from stop the left wheel it like makes a "clicking" noise as the car starts accelerating, once in motion there is no "clicking". What might cause it?
View 6 RepliesSonata NF (2006-10) :: Rotational Grinding Noise When Accelerating Through Hard Left Or Right Turns
I have a 2007 Sonata 3.3 V6 GLS (CDN model) with 102k km (63K miles). Recently, I am noticing a rotational metal-like grinding noise from the front left wheel / engine area when engaging in hard right and left turns - usually a long looped highway on-ramp or sharp 90 degree turns. The interesting thing is this only happens when I am accelerating through the turns - when I left off the gas and cruise I don't hear it anymore.
On the side, I am also getting a single clunk noise when shifting from Park to Drive and vice versa from the same area (front left wheel) - not sure if this is related (i.e. if this is all related to a failing CV joint or wheel bearing).
Sonata NF (2006-10) :: Clunking Noise At Low Speeds / Braking Or Accelerating Away From Stop Lights
2007 Sonata 3.3. Crunching, clunking noise at low speeds, braking or accelerating away from stop lights. Noise disappears at speeds over 25-30 mph. Noise can be replicated by rocking car forward and backward while in park, with engine turned off. Rocking side to side does not reproduce noise. Bouncing car suspension at all four corners does not reproduce noise. Hood open, rocking forward and backwards, noise seems to be coming from behind engine, and with hand on engine motion can be felt. I'm thinking engine mount, but how can I get a good look at it to check?

I purchased a 2007 Sonata with the 3.3L about six months ago. I really like the car, it has a lot of good features and lots of power; however, I am starting to have problems with the car. On accelerating from a stopped position the car almost quits (hesitates severely) and then picks up and goes on normally. Also, between 40 and 50 mph the car starts to jerk pretty hard for a few seconds and then it straightens out and runs normally again; it will do this repeatedly if it is kept between 40 and 50 mph.
When this first started happening the CEL would come on randomly and stay on for a day or two and then go off. While the CEL was on I took it to Autozone and had them pull the code, they said it was the crankshaft position sensor. Well based on the symptoms the diagnosis made sense. I replaced the sensor and the car seemed to be running normally on the 30 minute test drive. The next day my wife drove to work and she said the same symptoms had come back. It has been several weeks since I replaced the sensor and the CEL has not come back on. I have seen several postings about the spark plugs and wires and that is my next step. BTW the car has 94k miles.
Sonata NF (2006-10) :: 2007 - Faint Engine Tick / Click Sound When Accelerating At Speed
I have been experiencing a slight issue with my 07 Sonata V6 lately. When I am accelerating, most commonly when already at speed around 80 to 90 km/h, I would hear this 2-3 ticks / clicks when I press lightly or moderately on the accelerator pedal. The car would accelerate fine without any further noises. When I release the pedal, the car slows down a bit, and I press on the pedal again, then the same sound re-appears.
View 2 RepliesSonata I45 (YF - 2011+) :: Slows Down When Accelerating?
I tried going up the driveway and as I was accelerating, I almost noticed a little "slowing down" while trying to accelerate up the driveway. It was really snowy so I am thinking that it might have been the ESC trying to fix the path. I thought about this after I got it up the driveway, so I couldn't test it.
Is this normal or should I have it looked at by a mechanic???

Sonata I45 (YF - 2011+) :: HIDs Pulsing While Accelerating
I noticed going up hill when the RPM's hit around 2100 RPM this morning it looked like my HID's went into a strobe type pulse. They stayed on but got brighter every partial second. Even from a stop if I accelerated with more than 2k RPM the lights flickered.
It's done it for two days, which happened to be in the single digits tempature wise. Do you think it's my alternator or my battery having the issues? Car is a 2012 so I'm leaning more toward battery load issues.
Sonata I45 (LF 2015+) :: Engine Shudder At 108km/h Upon Accelerating
Well, my MIL came on, and hasn't left (yes, my gas cap was tightened). My bigger concern is that when I'm on the highway, if I have to slow down for traffic, upon accelerating again, when I hit 108km/h, the car does a crazy death shudder, and slows down...I have to release the pedal, let it slow to around 95, and then I can accelerate again. I'm gunna wait and see if the light goes off after a couple of days, but this is worrying.

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 7 RepliesSonata I45 (YF - 2011+) :: Excessive Engine Noise In Cabin Especially When Accelerating From A Very Low Speed
I recently acquired a 2014 Sonata Limited 2.4L. Don't know if its me or not but engine noise seems to be excessive in the cabin especially when I am accelerating from a very low speed, almost like something in the engine is loose. Had it at the dealership today for warranty work (seat belt) and recall work and asked the techs to take a listen when the do their inspection. They came back and said that the noise is coming from the electric fuel pump and that it is totally normal. Previous car I had was a 2011 Honda Accord Ex and it seamed quieter.
View 1 RepliesHyundai - Sonata :: Hesitates And Sputters, Mostly In Lower Gears When Not Accelerating Hard
I recently bought a 2004 Hyundai Sonata 4cyl with about 65k miles. In the past few months I've noticed that it likes to sputter and hesitate at times, mostly in lower gears when I'm not accelerating hard. At highway speeds it's mostly fine. It's also fairly random - some days it's really bad and others it's fine. Also seems worse when in reverse. I don't think the plugs have been changed so that's one idea, but I'm wondering if it's a bad fuel filter, exhaust manifold leak or something else. It's not throwing any codes (and yes the light works) and it has never stalled completely out.
