Sonata NF (2006-10) :: Loss Of Power / Rev Up When Pushed The Gas

well I don't exactly know if that's what I should call it... I was driving last night around 10 and I pushed the gas down 3/4 of the way or so to pass around this car but instead of downshifting and accelerating, it just revved up all the way, i kept hitting the gas and it was like revving it in neutral then it kicked back into gear... should i be concerned? It was fine the rest of the night but I wasn't driving it hard.

Sonata NF (2006-10) :: 2007 - Occasional Power Steering Loss

My daughter's 2007 Sonata 4 cyl (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 steers like an old classic without power steering - then can.

This is kind or a repeat post from another individual but he had a V6.

SBR711 recommended replacing the Harmonic balancer and I am inclined to do so but parts guy at Hyundai said that typically is not an issue in the 4 cyl model. So he does not keep item on hand.

Fluid is fine, clean and proper level. No screeching etc..

Sonata NF (2006-10) :: Occasional Loss Of Power Steering While Driving

I've got about 80K miles on my '06 Sonata and the weather conditions were on the very wet side.

At first I thought I heard a squealing sound which I just credited to either a radio or windshield wiper sound while cruising through some twisty coastal roads. The rain was coming down pretty good and a small amount of standing water of already on the road.

As I continued my drive I began to notice an occasional loss of power steering for a split second through some turns accompanied by that same belt squealing sound. At the same time the battery light also came on for a split second which indicated to me possible engine failure for a split second. Even though it was for only a split second it really freaked me out to think I could end up crossing the center lane or over into the ditch. I then slowed my pace for the rest of the trip. When I stopped for gas I popped the hood and things appeared to be normal and with plenty of power steering fluid.

Sonata NF (2006-10) :: 2007 - CEL / Sounds Like A Diesel And Loss Of Power

I have a 2007 Sonata GL. So tonight after work when getting into car to go home I noticed my CEL came on, also as I was driving at low speeds/rpm I noticed the car really sounded like it has a diesel engine in it. At higher speeds on the highway I noticed it has some loss of power and the diesel sound went away. CEL stayed on.

The CEL light I am pretty sure is the OCV which I havent replaced yet. So my question is: Can the OCV cause the car to sound like a diesel and have loss of power is that caused by something else?

Sonata NF (2006-10) :: Idling And Power Loss - RPMs Will Drop Below 500 And Then Spike Back Up

So over the last few months I have been having more and more idling and power loss issues with my 2006 V6. When idling she intermittently will try to stall and the rpms will drop below 500 and then spike back up. A large percentage of the time I hear a loud whining sound while driving down the road and I notice that turning off the air conditioner will remove the sound at times.

***what I have done so far**

Idler Pulley
Belt tensioner
sepentine belt
cleaned MAF
Cleaned Throttle body
Throttle Position Sensor
Had car reprogrammed

So I pulled the belt off and checked all the pulleys and did notice some grittiness in the AC pulley (inner) and was wondering if this might be the issue. Attached is a video I uploaded, Video .....

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).

Ford 6.0L Power Stroke Diesel :: 2006 F250 - Lack Of Power / Truck Will Barely Move And Takes Long Time To Accelerate Under A Load

I have a 2006 F250 6.0 Amarillo Edition. 133,000 When I bought the truck it was a theft recovery vehicle where the turbo, injectors, FICM and wiring harness were stolen. The company I bought it from replaced the injectors, wiring harness-new, and a used FICM, and turbo. Also has EGR delete and SCT tuner with basic tunes. I believe the SCT was put on to mask another problem. No dealer would spend that kind of money to sell a truck unless something was wrong. The truck would accelerate some with the tuner but shift the tires so hard it would bark them. I removed the tuner and went back to stock program.

The truck will barely move and takes a long time to accelerate under a load. In park and neutral it is fine. A friend has a ford diagnostic program on his computer and says the readings were all good except EBP was a little high. Removed exhaust and air intake to verify no restrictions. Turbo sounded like the vanes might be sticking so I replaced the turbo and VGT solenoid. Now truck feels like its trying to make more boost but not transferring power to the engine. Have blown the silicone hose off twice now during testing. Checked the EBP sensor and tube and only thing I see is a little carbon buildup inside the sensor. What else to check. I'm new when it comes to diesels.

Sonata NF (2006-10) :: Temporary Loss Of All Electric In Car

For the past few weeks I have had a bizarre issue with my 2010 Sonata GLS. If you unlock all doors (press the FOB unlock button twice), get in, close the door and then turn the key and attempt to start the car, all power is lost to the the interior and with no lights, radio etc. The car is literally dead and won't start. If I open the drivers side door and then close it again, all power comes back and I can start the car. All radio stored stations are lost, the clock is reset and usually the trip odometer is reset too. Other times, if I just press the FOB unlock once to unlock just the drivers side door, the issue does not apparently seem to happen. What the issue may be?

Sonata I45 (YF - 2011+) :: Loud Knocking Noises And Power Loss

My car shifted wrong (i don't know how since it is automatic) and heard a loud knocking noises and lost power and then she shut down and turned off. called Hyundai assurance and they towed it to the nearest dealership since my dealership is an hour and a half away from my school. I don't know how this happened. I tried to crank it back up. heard a loud squeal maybe water pump? and she turns on but the rpms wouldn't go past 500 rpms well there she goes.

Sonata I45 (YF - 2011+) :: Complete Loss Of Power Suddenly Then Reactivated On Its Own

My son is primary driver of our 2011 Limited with push-button start. He phoned me a few minutes ago to tell me he was driving--everything normal-- when there was suddenly a complete loss of power, mechanical and electrical (engine died, dash lights out, nav screen dark, etc.). There was no advance warning of any kind.

The power loss was total but brief, two or three seconds, and then reactivated on its own. My son said he pulled off the road into a parking area, stopped the engine, waited a few seconds and then restarted and is on his way home with everything working normally so far.

First issue with the Sonata--61k miles ....

Hyundai - Sonata :: Cylinder Misfire / Power Loss While Going Up On Steep Hill

I am not a mechanic by any means, but have picked up a lot of stuff over the years. I drive a 2003 Hyundai Sonata with a 4 cylinder engine. Several days ago while going up a steep hill I lost power and my check engine light came on. This has happened before when my coil went bad so I figured it would be a breeze fixing it. I limped it home and ran the code. Sure enough it came back as cylinder 1 misfire. This vehicle uses 2 coils so I swapped them to try and get the problem to follow, but it did not. I have tried a new spark plug, new wires, and swapped injectors without success. There is still no activity on cylinder 1.

I ran a compression test. I get about 60 PSI on cylinder 1 and between 180-210 on 2-4. This would point to head gasket, so I am told. I do burn about a quart of oil every 500-1000 miles, but I do not seem to have any coolant leaking issues. I have not noticed any smoke from the tailpipe. The spark plugs were generally good looking, except for number 3 which had a hard white substance all over the electrode. There does not appear to be any oil in the coolant or coolant in the oil. This seems strange to me as everything I have read said that one of those would happen.

Is there anything else I should look into or is my engine toast?

Sonata I45 (YF - 2011+) :: Loss Of Power / Falling Out Of Gear - Brake Light Stays On

I recently (July 2016) bought a 2012 2.0T Limited with 14K miles. Got an awesome deal on it and really love the car. About two months ago the car had a total loss of power/boost. I took it into the dealer and they performed a wastegate actuator adjustment (something I will be doing on my own now if it becomes a problem again). Now at about 21k miles I'm having a different issue. Here is what's happening:

Accelerating from a stop the car feels as if it's falling out of gear intermittently. Once it happens and I press the gas more/floor it, the car doesn't respond. If I let off the gas and then press it again, the car will then start to accelerate again. On the highway cruising at 70ish, the same thing happens and it even oscillates with constant throttle like its down/up shifting. The ESC light came after a 20 mile highway trip of this oscillation. No CEL. When I got off the freeway, the navigation screen said there may be a problem and I should press the bluelink button.

When this is happening the cruise control either doesn't work at all or the "cruise" light will come on but I can't set a speed. Tonight I noticed in the rear view mirror that the brake light stays on or even flutters after I brake which corresponds to when the cruise is or isnt working as well as when the car intermittently falls out of gear/oscillates falling out of gear with constant throttle. If I notice the brake light is on without actually braking, I can take my foot and pull the brake pedal towards me which turns off the brake light and then the car seems to work correctly as well as the cruise control. The car is driveable but definitely something is wrong.

I should mention that I checked the voltage for the wastegate actuator and it is 3.97v which I believe is within tolerance. All of these issues with no CEL.

Ford 6.0L Power Stroke Diesel :: 2006 F350 - Loss Of Power When Towing Up Grades

My dad recently bought 2006 6.0. He has had it about 2 and half months. Has the egr delete kit installed. The truck has ran great. Up until Wednesday the 3rd. My dad headed to Ut to pick up our new quads. While heading up a small grade with empty trailer in tow. Truck went to limp mode, fan kicked on, orange wrench came on on dash board. He pulled over let her cool down turned her off.

Checked fluids Then started her back up and she was fine. That has happened 3 times. Now he is on his way back (tow haul mode turned on) and it is doing it again. She hasn't went into limp mode yet. As soon as the fan kicks in my dad pulls over immediately and puts it in park. And lets her cool down checks fluids. This issue only happens mid way up a grade. So my question is...... What is causing this? How do we fix her and make her a happy truck again.

Sonata I45 (YF - 2011+) :: Intermittent Power Loss When Entering Moving Traffic From A Side Street Or Driveway

I recently (3/3/14) purchased a 2011 Sonata Limited 2.0 with only 6750 miles. I've owned it for 3 weeks and put 2000 miles on it. So far, lots to say good about it but one very disturbing quirk- on occasion, when accelerating from a stop in traffic or when entering moving traffic from a side street or driveway, there is a sudden loss of power. This power loss lasts from about one second to as long as 3-4 seconds before the engine recovers and the car resumes normal acceleration. I've taken it to my local Hyundai dealership twice with this complaint, but the defect is intermittent (technician was unable to duplicate it at the time) and there is no defect code to be found.

Accent MC (2006-11) :: Significant Loss Of Power

Accent 2008, 130000km

For several days my accent has quite a significant loss of power (I have trouble reaching 100km h) and the check engine is on. At the beginning I thought it was a coil that was lacking but I have verified and 4 are ok. I verified the check engine codes and got the code 420 inches and po172. po = 420 capacity threshold and lower catalyst po = 172 system too rich .... I do not know what to do with that! can you recommend me a good Mechanic on the south shore of mtl.

Lexus GS 2006-11 :: 350 AWD Slip Indicator - Power Loss At 55+ Mph?

I recently purchased a used GS350 AWD.After purchasing it, I replaced all of the wheel bearing hub assemblies. The rear ones were grinding, and I decided to just do all 4 at the same time.

After swapping the hub assemblies, the slip indicator light comes on when I go 55+ mph. It's usually when I push on the accelerator. It's not always on. It goes on, then turns off for a while. Sometimes when accelerating it doesn't come on at all. When the light turns on, I loose power for a few seconds but I don't hear or feel any braking.

I have tried an alignment, reset the YAW sensor, etc. The mechanic had a very expensive snap on diagnostic computer and he said everything seems to check out. The steering angle is good, acceleration looks good.

I'm thinking that either one of the hub assemblies has a slight defect that affects the ABS sensors, my VSC computer needs replacing, or YAW sensor starting to go bad.

Prius (2004-09) :: 2006 - Red Triangle And Loss Of Power

Purchased a used 2006 prius with ~180K miles on it from south bay a few months ago. At the time of purchase the guy warned us that it 'ate' motor oil.

After 2 months of driving without issues (driven couple of hundred miles), on an uphill road the engine overheats and throws the red triangle, vsc and check engine lights on the dash, along with loss of power. After cool down I check oil level and sure enough it is low, since this is on top of a hill we essentially coast all the way back home without any real issues. Once home I top up the oil. I do a test drive around the block without issues (no loss of power) though the check engine/red triangle/vsc lights are still on. But after I take it for a longer drive the loss of power returns.

Since my bluetooth obd2 connector wasn't working I borrow one from my friend and try to get a read. Unfortunately the thing puts out no obd2 error codes. Living in the bay area I apparently cant just take it to an autozone, to get code readings. I take it to meineke auto repair, they too are unable to get an obd2 read, and want to charge me $100 for a full reading, which I decline.

I do a few diagnostics steps including 'resetting' the computer by leaving it off of the 12v battery for a few mins, this clears the red triangle et al on restart. I do a test drive, at first everything is working just fine, but after about 10 mins or so of driving the red triangle/check engine/vsc lights returns, along with loss of power. (under ~20 mph only, cant go uphill).

Take it to a mechanic and they come back with code: "APOA92. Trans Axel issue - MG1 performance is off. Measured torque is different than executed torque, enough to be a problem. 95% sure it is the transmission." I still haven't checked the 12v battery.
