Sonata I45 (YF - 2011+) :: Dome And Head Lights Pulsating
Having some issues randomly in the car, the dome lights/headlights are pulsating. Like the power isn't there. I have LED's connecting the battery, so I am thinking it might be a problem with the ground on teh battery. I know I can eliminate everything but the LED ground.
View 5 RepliesSonata NF (2006-10) :: Humming Noise Pulsating On And Off
I have a 2009 Sonata GLS with about 45,000 miles on it. Lately when I am driving over 50mph it has been making a very annoying, high pitched humming noise. The noise seems to pulsate on and off. If I am going in a straight line, the noise is present, pulsing steadily. If I turn right, the noise speeds up and gets louder. If I turn left, the noise slows down or goes away completely. The noise is not super loud yet, but it is driving me crazy.
I took it into the dealership and they said it was a tire problem - one is worn more than the others (though not so much that it needs to be replaced yet)
From what I have been reading online, it sounds to me like it's a wheel bearing problem, and possibly the worn tire is a symptom of that problem. However I have also read that the average wheel bearing should last about 100,000 miles with proper maintenance. If it is a wheel bearing, it should be covered under warranty, shouldn't it?
Sonata NF (2006-10) :: 2007 - Brakes Pulsating (when Applied) At Highway Speeds
I recently bought a 2007 Sonata V6, and the brakes pulsate (when applied) at highway speeds, so I am looking to replace the front rotors & pads. I have been told that the OEM rotors/pads aren't great & that as a result many owners have a brake pulsating/vibration issue.

I started my car last evening and it hesitated and balked and the check engine light came on. It started fine this morning, but would not go above 30mph even with accelerator down all the way. I checked the diagnostic codes from Bluelink and it said there is a possible condition with my Engine Control System and should be checked soon. The car only has 4,000 miles and has been fine until now.
View 5 RepliesSonata NF (2006-10) :: Hesitation For A Second Or So When Floor The Accelerator
About once every 4-6 months or so, when I floor the accelerator, my Sonata behaves in a very odd way. Instead of the typical surge of acceleration, it actually hesitates/decelerates for a second or so, then kicks in like normal. This is so pronounced that I lunge forward in my seat a bit before it kicks in. I've not yet been in a situation were this behavior has endangered me but it is quite disconcerting when it does happen. Obviously this is not something that is repeatable in a manner for any shop to diagnose. There is no CEL and it occurs so infrequently that I'm not that concerned about it yet. The only consistency about this is that this occurs while driving around town after I've slowed down to around 5-10 MPH approaching a light, taken a right turn and then attempt to accelerate into traffic. Since I'm usually in a turn lane, I'm out of the way of traffic and can adjust to this situation without any issues to either myself or the traffic around me.

Noticed that when drive Sonata cold without having it warmed up and you hit the accelerator even a little bit that it 'jerks' back a bit? Once the car is warmed up you don't feel it anymore.
View 11 RepliesSonata NF (2006-10) :: Codes P2128 And P2110 - Accelerator Pedal
It was the throttle body thing, cleaned that completely. Replaced the pedal with one from the bone yard. No change after clearing codes, the check engine light comes back the second you touch the pedal. Have a new (reman) throttle body coming tomorrow as I may have dinged it up after cleaning it again, I took it apart to see if I could see anything obvious.
Cleaned the carbon tracks inside and bent the brushes up more to contact the tracks better. I doubt it liked that. It was throwing a code for high current, but now that has disappeared. However, I used to be able to rev it up to 2500 rpm, now nada.... So I am left wondering if this is a bad ground or something? Bad wiring to the ECM:?
I would love a schematic showing where any relevant grounds are, pin out voltages etc. It is -15 here. The closest I've come so far: [URL] ....
Sonata I45 (LF 2015+) :: Engine Lost Almost All Power When Pushed The Accelerator At 30 MPH
I pushed the accelerator all the way to the floor at 30 MPH and the engine lost almost all power? As soon as I let up to about 9/10 throttle everything reverted to normal. Took it to the dealer and it showed no codes. The Tech and I took it for a road test and it did it only one more time. He said to keep an eye on it but was baffled. I tested it later in the sport drive mode and it would bog down every time if pushed hard to floor at about 30mph.
My best guess is that I got some bad regular low octane gasoline and the ECM is sensing a knock and retarding the timing or cutting off fuel flow similar to over revving condition. I will fill it up with 93 Octane Premium next time I get fuel and se what happens. Usually runs fine on 87 Octane but most of the time I don't floorboard the accelerator pedal. As I said at 9/10 throttle it runs fine.
Sonata NF (2006-10) :: Accelerator Pedal Pushed - No Response / RPMs Not Increasing At All
Just got into my 2006 Sonata V6 this morning. 120,000 miles. Drove last night, no problems. Started her up now this morning, noted check engine light and ESC lights on.
Pushed accelator pedal, no increase in RPMS at all. Put the car in gear (auto), car moves forward and backward, but pressing the pedal doesn't increase the rpms at all, so right now its not driveable. Luckily, its in the driveway so I know it could be worse. Took floor mat out, no interference issue there.
I changed the starter solenoid and that was over 45,000 miles ago. Never had that problem.
Sonata NF (2006-10) :: Squeaking Noise Coming From Engine When Press The Accelerator
I have a 2010 Hyundai Sonata GLS 2.4L. This problem started several weeks ago. When I turn on the ignition on the car, I hear a squeaking noise coming from the engine initially. Once the engine warms up, the squeaking sound lessen but does not go away. When I shift my automatic transmission to DRIVE, and press the accelerator, I hear squeaking noise coming from the engine again. I stopped my car and opened the hood. I could hear the squeaking noise coming from the front left of my car, if you are facing forward the front of the car. I do not know much about cars but I think it is coming from the fan belt/serpentine belt, or possibly alternator but I am really not sure.
Presently, the sound has gotten worse so I want to fix this as quickly as possible. I am second owner and the mileage on the car is 45,550.
Ford F-150 (2009-2014) :: 2011 - Engine Stays At Higher RPM When Press Slightly On Accelerator
When I press slightly on the accelerator just to get the truck moving and than let off the engine stays at the higher RPM typically just over a 1000. This only happens in drive not reverse and everytime I just slightly step on the accelerator. The truck only has 1K miles on it.

I just replaced my OEM battery with a duralast from autozone. The battery had 138,000 miles. Shortly after, the check engine light came on and code says P0106. Map Sensor. Seems like to much of coincidence that this happened. Have read that disconnecting battery cables for 3 hours may do the trick.
View 8 RepliesGolf/GTI VII :: Pulsating Vibration At 70 Mph
For the last two months I've been having pulsating vibration at 70 mph (68-72) in the gas pedal. I brought it into the dealership 3 times now and then assure me nothing is wrong. They checked wheel bearings, alignment, rebalanced the tires, and even drove other 2015 GTIs and claimed they had the exact same pulsating vibration in the pedal at that speed. (If that's truly the case, which I don't believe, that's a big issue).

THis is about the 5th or 6th time in the past year (2X in past 2 weeks) that the A/C will not come on. Two times took to Dealer & it worked just fine. Ir worked when I drove it, then parked it for 2 hours, and then it wouldn't work. Parked it, and then it worked fine again.
Dealer has no knowledge of this being an issue.
Similarly, my iPhone does not connect on an intermittent basis - again, always connects when at dealer.
Lexus GX 2004-09 :: Pulsating When Warm Up And Braking
05 GX 470...no KDDS...100k miles. When I've been driving a few miles, I feel a pulsating when braking. Feels like it's coming from the front (front left if I had to guess). I put in new rotors and brakes in the front, turned the back rotors and problem still persists, no improvement.
I'm now considering the hub-bearing. However, when I do the standard-check (lift wheel and apply stress from top/bottom) there's no indication of a bad hub bearing.
The problem worsens as I drive faster. When on the highway, if I start to turn the wheel right 'then' brake...the steering wheel pulsates bad. When I turn the wheel left 'then' brake, it's not as bad...but still noticeable. When I start pressing the brake pedal 'then' start to turn the wheel right it's still there but not as bad compared to applying the brake after turning.
There's no pulsation in the break pedal, only the steering wheel and body/chassis.

View 3 RepliesFord :: Brakes Malfunction - Pulsating When Braking
I just had new rear drums put on, my front brake pads are new, my rotors are good...but there is still a pulsating when I brake. When I am just about slowed down you can definitely feel a surging coming from somewhere. The steering wheel does not shake, and I don't feel more than a vibration from the brake pedal. I have taken it to 3 mechanics and replacing the drums was given as a solution. But since I have already done that, the problem is obviously not resolved. I know I need new tires as 2 of them are really cupped and loud...could that be it?
