Sonata NF (2006-10) :: 2007 - Severe Hesitation / Car Almost Quits On Accelerating From A Stopped Position

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) :: Engine Knock And Check Engine Light Came On

I recently got a Sonata from my parents when they moved to Pennsylvania. It's a 2007 with the 2.7 liter engine. It has had low oil for some time, so when I got it (last week) I put more in, up to but not above the full line.

It has had now for just a couple of days a very bad rattle, which is barely audible (but still IS audible) at idle and gets very severe during and after acceleration. It remains for some time even after the gas is no longer being pressed, then subsides a bit. I diagnosed it as knocking, but just today the check engine light came on and the rattle got louder.

I don't have another car to drive and I have class in five hours. Should I drive it or call a cab?

Sonata NF (2006-10) :: ABS / ESC Light Comes On At Same Time - Front Brakes Squeak In Turns Only

The ABS and ESC lights (amber) in my 06 Sonata are coming on intermittently.....

The lights just come on while driving....the ESC switch doesnt have any effect.....the brakes seem to work well....then, after several start cycles the lights will go out and all will be well again....then after a few start cycles and while driving they come on again.

I used the code tester from autozone but no codes are stored...they told me that brake codes aren't always accessible with their hand held unit though....

Also, I have noticed that when turning left or right I get a squeaking from the front brakes now and then,...it was doing this before the ABS/ESC light issue though...

Sonata NF (2006-10) :: Check Engine / ESC Light And Cruise Not Working All The Time

However I did get a code for the brake light switch and replaced it. Then the same code happened again and everything started acting up and not working again. The strange part is that even though I got the brake light switch code my brake lights still work. The only thing that stops working is my cruise control intermittently.

Sonata NF (2006-10) :: Can Oil Temp Sensor Knock Out Airbags?

I went to Jiffy Lube and got an oil change, fuel system cleaning and cabin air filter replacement & sanitizing. I drive an '09 Sonata with 112K miles. When the car came out, I pulled away and noticed that the airbag symbol on my dashboard was lit and the center console was flashing that my passenger did not buckle their seat belt (I didn't have a passenger or anything on the seat). I went back in and after they looked at it, they said they couldn't find anything that could've happened at anytime and was a "horrible coincidence."

Hyundai ran a diagnostic tests and one of the 4 things that came back was B1389 (in addition to B1516, B1324 and B1515). B1389 signifies "Oil Temperature Sensor Circuit Failure." If the guy changing the oil damaged this (does this even get touched on an oil change), could that have offset the sensors for the airbags?

I just don't see how they done the above listed work and coincidentally my airbags are all deactivated afterwards. I'm reading a lot of bad reviews online, including quite a few for NOT putting oil back in the engine after the change.

Sonata NF (2006-10) :: Slight Knock When The Car Shifts Into Third Gear

I bought my sonata with about 48,XXX miles about 2 months ago, and now it has 52,500 (im a student - dont drive much). Anyways, whenever i start my car up and drive down the road, when the car shifts in to third, i hear a slight knock. almost like a little gong - metal on metal.
Once it does it the first time, it doesnt do it anymore. Im guessing temperature could have a factor?

Sonata NF (2006-10) :: Transmission Knock When Shifting Into 2nd Gear

I noticed that recently my 2007 Sonata (108k Miles) is making a knocking sound when it shifts into second gear. It happens only when I back out of my garage and drive down the street and the car is cold. After that there is no more noise, and the transmission is shifting through the gears smoothly.

I recently replaced the transmission fluid, about 5k miles ago and I used the recommended type.

I read other postings with people having the same problem, and in those cases they pointed to the ABS self-check which occurs when you first start out. But this is definitely not my case as the noise is coincidental with shifting into 2nd gear and it only does it when the transmission is cold.

Could this be caused by the fluid temperature or maybe because the fluid has not had a chance to circulate through the transmission and fill all the cavities? Its rather strange thought that I just noticed it in the last month or so, if that were the case I should have had this problem before.

Sonata NF (2006-10) :: Clunk / Knock From Front Driver Side

Recently got quite a noticable clunk/knock from the front driver side of my '10 Sonata with the 2.4.

Only happens at low speeds, most notably in parking lots.

My best guess is a stabilizer link or a ball joint.

Took a video to explain the sound I am hearing.

Sonata NF (2006-10) :: Oil Light Flickers / Helicopter Sound From The Engine

My 2006 sonata (3.3l) 108k miles has developed a recent problem. The oil light will come on (usually during acceleration) and then go off in a second. i guess you could call it a flicker. I also notice a helicopter sound from the engine. When I rev it up in park I don't hear it. i hear a slight rattler In the alternator area. the serpentine belt is original.

So last week my daughter got the oil changed. I noticed it was leaking oil. I checked fluids and it was fine. I noticed oil on top of the engine, I just thought they spilled some. Continued to leak. checked the oil again and it was approx. 1 3/4 quarts low. The oil light never came on. I suspected the oil filter (its on top of the engine). brought it back to jiffy lube and they said the filter was loose. they gave me a new one and filled up the oil. no ticks or engine noises were noticeable.

So my question is could the oil light be something else (maybe tied to that helicopter sound)?. is an oil light flicker always low oil pressure.

Sonata NF (2006-10) :: AC Blowing Hot Air / Green Light Lit Up But No Loud Clicking Sound

AC does not work on Sonata 2006. It blows hot air.

1. Freon pressure is high level in red and I didn't add any new freon.

2. Checked fuse 7 A/Con and 19 A/C Relay and both are OK.

When I click on AC on/off green light on AC panel the light is lit but I don't hear any loud clicking sound.

Sonata NF (2006-10) :: Slight Whistle Sound - Engine Management Light Started To Flash

Earlier today on a easy drive (not pushing it) I noticed a slight "whistle-sound" that I haven't noticed before. About then it became VERY sluggish and the Engine Management Light started to flash.

As soon as I could I pulled over and connected my AL619 and it says "to low turbo/supercharger flow".

I didn't notice any smoke or smell, just a serious lack of power (i was doing 30km/h at the top of the hill).

Just tried to locate the leak, but I cant feel it or see it. I guess one would need one of those "smoke generators" to see where the pressure goes out.

So, do I have a broken turbo, or just a blown turbo pipe/tube?

Dodge - Dakota :: 1993 - Quits Running At Any Time / From Right After Startup To Going Down The Road

My 1993 Dodge Dakota quits running at any time, from right after start-up to going down the road. It wont start running again until the check engine light comes on when the ignition is turned on. I can sit there from a few seconds to five minutes before the check engine light comes on. I have cycled the key three times to check for a code, but there are none. I have checked much of the wiring to the relays and some to the PCM, but have found nothing wrong. This truck did the same thing with the two previous owners, and had the PCM replaced, to no avail.

Sonata NF (2006-10) :: Rattle Comes On Any Random Time

I've bought 2006 gl sonata 2.4. Car sounds good though rattle noise comes on and go of any time. I can drive my car for an hour and never hear anything, or i can just start the engine and hear the rattle. The noise is the same all the time though it could be louder or more silent randomly. My AC doesn't work. One friend of me said it must be AC compressor that starts and stops by itself because of the some magnet in it. Could that be true or there is a different reason?

Sonata NF (2006-10) :: V6 Brakes Squeaking All The Time

I am asking this question for a friend of mine that lives about 2 hours away from me. She is having trouble with her brakes squeaking all the time. She just had new pads put on the car about 2 years ago. She stopped by a brake shop and they said the pads are good but the rotors have something on them which is making the squeak. I told her the rotors could be turned down to remote the varnish but she said the guy told her the rotors could not be turned down. Since she has moved since she had the new pads installed there is no way to get them to do it correctly. How to make the brakes stop squeaking short of changing the rotors.

Sonata NF (2006-10) :: Squeak When Turning Left (then Later, All The Time)

My daughter has been learning how to drive on our 2010 Sonata GLS, which stands at about 108k miles. We've done threshold braking, ABS activation, some higher lateral force slalom-type stuff, etc. Suffice it to say that we haven't gone really easy on the car.

Now, there is a squeak that began at first at low speeds turning left. The squeak seems to be about one wheel revolution or so (speeds up when our speed increases, slows when the car slows).

After 30-60 minutes of driving around town (city driving and some rural), the squeak happens even when driving straight ahead. We haven't had any suspension work done on this car. I replaced the rotors and pads on all four corners last summer (and bled the lines).

What are the most probable causes of this (and what are the fixes), so I can start tracking it down.

Sonata NF (2006-10) :: Starter Doesn't Crank All The Time

Random issue that has progressively been getting worse. I'm assuming it's one of those Sonata quirks that we all deal with.

When you turn the key the starter doesn't try to crank the engine. AC stuff all works properly. I just keep turning and eventually it will turn on.

Sonata NF (2006-10) :: Long Crank Time (8 - 10 Seconds)

I have a 2006 Sonata GLS with the 3.3L V6 and close to 230,000 miles. A few months ago I noticed that my crank time at starting was longer than typically - it has steadily gotten worse.

Now the crank time is close to 8 - 10 seconds. (Which might not seem like much but trust me, it is).

I suspected that the fuel pump was faulty, however, once started - it runs great.

I put a pressure gauge on the fuel pump outlet and found that it only kicks the pump on when the car is cranking, the fuel pump does not kick on when the key is in the "on" position. Once the vehicle starts, it seems to be drawing fuel.

The pump has all sorts of pressure, I am not worried about that.

I decided to change the Fuel pressure regulator valve thinking that maybe it wasn't holding pressure - That didn't seem to do anything.

Do I need to change the entire Fuel Pump Assembly?

Sonata I45 (YF - 2011+) :: Engine Quits When Brakes Applied

Car started fine but stalled on first brake application with the skid-control light illuminated, restarted fine but stalled again on next brake application (skid-control light stayed on). Decided to head for the dealer which was only a few blocks away, drove there knowing that it may stall when brakes were applied (engine would start, idle and operate when driving but the problem would only occur on brake application.... approx when the transmission would down shift to third or second gear). My last stop before turning into the dealer's parking lot, the engine quit and refused to restart.... finally came back to life after about 5mins and was able to complete my somewhat dangerous trip (whole journey was on very quiet back streets). At first I thought it could be related to the infamous brake switch but the service rep informed me that they couldn't communicate with any control module with the scan tool. Now I sit and wait, hopefully they will call with some good news soon.
