Santa Fe (CM - 2007-12) :: 2010 - Clunk When Accelerating And Loss Of Power
May 29, 2016
My wife has had her 2010 3.5 Santa Fe since new. Over the past year it's been having a clunk develop when accelerating, happening a few times from a start until highway speed. The clunks almost feel as if one is driving over bumps - that's what I thought at first. The power doesn't seem to be there anymore either. I have been driving her vehicle the past three years and it was fine when I first started driving it. But the past couple years I first noticed a problem and it seems it is getting progressively worse. My wife now notices it quite a bit too.

The diesel filter water level light came on today and I noticed a lack of power. I drained of the water which made no difference so I replaced the filter which still made no difference . The light is still on and the engine is powerless from 2000 rpm .

I was driving down the road and the car was driving great. all of the sudden I heard a clunk and the car lost power and started shuddering. I made it home and cut the car off. When I start it now, the car runs rough and stalls out. I can't get it to a place to check the codes so I am trying to self diagnose. I was thinking it might be the MAF so I took it out and cleaned it well. there is still no change in the way the car runs. it seems like the fuel isn't getting to the engine as I put my foot on the gas pedal it stalls out. I'm not too excited about buying a throttle body if it's the MAF. It could possibly be something else.

When I bought the car a few weeks ago, there was a p0507 code for a high idle in park, about 1300 RPM, but sometimes shooting up to 3000 when I shifted into park and then dying down. The code goes on and off intermittently. Not that big of a deal at first. Then I started noticing that if I revved it in park it would take forever to die down to 1300, and sometimes would fluctuate around 2000. I also noticed hesitation while accelerating around 1500 RPM and the transmission hunting for gears while accelerating, as well. I noticed my throttle cable was very slack so I tightened that, and bought myself a throttle position sensor, thinking that might be the problem, but didn't install it yet.
I was driving on the freeway yesterday in cruise control and then I started losing power while my foot was on the gas. With my foot on the gas, the throttle would cut out every second. I was basically one second of throttle, one second of no throttle, all the way down the highway. Almost impossible to drive. This continued even after I turned cruise control off. I limped my way to Home Depot and installed my TPS in the parking lot, and drove most of the way home with no issues, although I still noticed a slight hesitation while accelerating. Alas, I tested cruise control again and then the throttle on/off problem started again, then I could barely drive the thing, even after cruise control was off again. I'll be returning the new TPS to Autozone today, since apparently that's not the problem. What's my next move?

I have owned this car for six months. The car now has 39K. The problem is getting worse.
Re: Lexus 2011 LS460 AWD
Subject: Hesitation / momentary loss of power when accelerating after turn.
When accelerating after a sharp turn with light to moderate acceleration, the car will have a momentary loss of power for about 1, 2, or even 3 seconds. This does not happen often, but perhaps once every two weeks and I cannot replicate the problem despite attempting to do so.
In all cases, I am talking about DRY pavement. It always happens after a sharp turn usually to the right. (Probably because most sharp turns are to the right actually it only happened once on a left turn that I will describe below.) Acceleration is light to moderate NOT hard acceleration.
In one case it caused a serious situation. I had just purchased gas and was entering a busy freeway. When accelerating, the engine had a total loss of power for a couple seconds as a large semi truck bore down on me with its air horns blaring.
I have a strong clue that may debug this problem. Once, when turning left, the car suffered a total loss of power. There was no traffic and I kept my foot lightly on the throttle. The car remained unresponsive. The engine did not stop, but it did not respond and remained this way for at least 5 seconds until I took my foot off the accelerator and then back on to the accelerator. During this period of suspended throttle, I noticed that on the right side of the dash an orange alert symbol was flashing I think it was a swerving car? I assume this indicated that the car was losing traction and the computer decided to cut power until traction was regained. But the pavement was dry, and the acceleration was normal. In no case did I ever sense that one of the wheels was slipping.

I have a 2007 Ford Fusion 4.0L AWD. One day I went to pass a slower car and accelerated rapidly, but the car responded with loss of power and shook to a stop and would not re fire. I took it to the dealership and they said two cylinders were not firing and a fuse was blown. I looked on the internet and some people said their coils go bad or plug wires. I asked the dealership if that was the cause and they said absolutely not, but it's the ECM. They replaced the ECM and 2 days later my CEL came on and I took it back to the dealership and they told me my catalytic converter was bad and I could drive it until I had the money to replace it. Then a couple days go by and I was passing a tractor on the highway, I slowed down to 45 mph to make the pass and as I began to accelerated I felt a thunk, then about a mile later it started cutting out and shaking. This time it would re fire but idle rough. I tried on/off 3 or 4 times then it idled o.k. I then took it back to the dealership and this time they said it's all 6 coils.

I'm not sure whether it's real or even possible. Starting this summer, when it's hot and I turn on AC, I feel loss of power from the engine. When need for speed, it's slow to accelerate. The engine is less powerful than when it's cool and no AC running. Is this possible? It's 2010 V6 AWD.

So, I experienced a brief loss of power steering yesterday that was rather startling, then today I hear about a recall on other models for the exact issue.

The car started rough idling and a few weeks ago while driving "lost power" momentarily. I went to take a look at it and even just idling it will randomly drop 1000 rpm, or when the gas is one in P it does the same thing. also the dash lights dim at the same time.
I pulled these codes (below). I cleared the codes and tried to replicate with no luck. The car had been sitting in a parking lot outside for a few days and it has been -15C. I asked if it seemed to only happen when it was warm (the week before it was +10C) and they said yes. It has been another week (still cold) and the codes have not returned.
Quick google of these codes suggests maybe a throttle position sensor and/or loose battery connection.

I am using a Hyundai Santa Fe (Petrol, 2011 Model) here in Saudi Arabia. On July 17 (11:30 pm), I was driving in a highway at about 80-90 kms/hr when suddenly my vehicle lost power (steering wheel, brake, etc).
Baed on the diagnosis of our company mechanic, it was an alternator problem. He said the alternator bearing got stuck up.
Prior to this incident, on July 7, the same vehicle got stalled twice while it's parked. In the first case, I was able to use it after jumpstarting. In the second case in the same day (4 hours after the first case), jump starting didn't work so they have to replace it with a temporary used battery. I noticed that I had a hard start (the engine responds only after 3-4 key ignition). After replacing the battery with new one, I was able to drive normally from July 9 to Jul 17, and then the incident happened as I described in the first paragraph.
Question: Is there a way to detect the alternator bearing problem before it actually breaks down? If there is, what procedure or predictive test is normally followed to identify potential problems in an alternator?

Driving 30 mph, oil light came on, immediate loss of power braking and steering. Engine did not stop, oil light disappeared yet still had loss of power steering and brakes. Still in D. Policeman had to stand on brake pedal to get into Park so that engine could be turned off. Towed to dealer in next state and dealer said cannot replicate so cannot fix.
Car is 2012 Santa Fe w/ less than 6,000 miles on it.

What's happening with my Santa Fe (3.5L AWD). In the past couple of weeks I'm seeing poorer fuel economy (about 15% worse) and the vehicle feels like it is down on power, especially in fifth gear. I mean, the vehicle works and some might not notice, but... There are no warning lights. Engine oil is slightly high (1/4 inch or less) and transmission oil appears to be correctly filled. Don't see leaks from this vehicle on the driveway.
I had an oil change about 3 weeks ago, at a Hyundai dealership, where I switched from regular to synthetic. I was told that no special procedure was required in making that switch, so none was done. About two weeks ago, the stereo system was dead one day. Would not turn on at all. In trying to troubleshoot I pulled the Audio and Radio fuses (there seemed to be three in the dash area), but they were fine and after I reinstalled them the radio worked again. Those are the only maintenance and other issues I've seen in months.
The vehicle has pretty new rear brakes and I don't feel unusual heat there. Could the switch over in oil types or electrical issue with the radio be related? I've done many hundreds of miles since both events.

When I start the engine it works fine while the motor is cold (idle normal all smooth). When the engine the temperature reach normal operating range the car loose power and idle drops to 350-500 rpm and if i am driving I can not go over 40mi/h. I drive a 2008 Sta Fe now with 96000 KM (~~60000 miles). A month ago the engine start shaking severely and knocking noise (like some spark plugs where not working), from this to now:
Changed all sparks plugs
Changed all ignition coils
Now this situation looks more related to temperature of the engine.

I just changed my stabilizer link front right side and it did not solve the single clunk noise that I hear when accelerating and braking.. although it did solve the "multi clunk noises and creaking I get that is now gone away.. but this other single clunk noise what else could it be from it does it when driving straight and there are no clunks when turning. I must add that is that I can hear it and its a low pitched clunk... and is also felt in the steering wheel.

We have had had our Santa Fe for a year, done 38000 km and love it. The car will start up and drive around town fine but as soon as the engine is under load at highway speeds or driving up a hill it loses all power.
In Automatic when this happens the gear will drop back to third. You can switch it over to manual mode and slowly accelerate back up to around 80-90km/hour with your foot flat to the floor but the rpm don't get above around 2000 to 3000.
If you stop and turn the engine off for a minute or so, when you start again everything will appear to back to normal but after another minute or two the problem will be back. The engine malfunction light comes on and sometime it's flashing but at other times it's constant.
The car's been in at our local Hyundai dealer for a week but at this stage they still can't quite figure out the exact cause of the problem. The code they pulled out suggested it was the exhaust particulate filter (apparently quite an expensive part) so they replaced that but it didn't fix it. They've also replaced the fuel filter and some temperature sensors that are part of the particulate filter apparently but still no joy.

I seem to be having a clunk noise coming from my car when braking to a standstill or accelerating from a standstill.
Its totally unpredictable but only happens when braking or accelerating under 10mph.
No noise when going over bumps or turning and its only heard when the windows are down. What it could be?

My issue can be while driving with cruise on, or accelerating, the truck just losses power, then recovers. At idle, the rpm can, but not always, fluctuate.
There is no "misfire" when it happens, but it just falls on its face. I have NO diagnostic tools, and my injectors are not stock, so I am unable to unplug my DP.
My thoughts are to unplug the ICP and give that a shot? Meanwhile, I will put in a order for a elm327

I have been hearing a whine for a while now that has gotten worse. Today I was at a stoplight and there was a clunk from the rear and then the car lost about 1/2 of its power. I noticed the height level adjustment was blinking off. I shut the car off and it all went away after restarting.

It's a 2006 Ford F250 6.0 diesel with 307,000 miles on it. Up until a week ago it ran great but when I was in a drive thru I turned it off (to order) then turned it back on to pull up but the idle was very rough and the truck shook as I revved it up but it went back to normal after I saw a puff of white smoke. Ever since then every few stop lights I will begin to accelerate but there isn't any power and it shoots out a lot and I mean a lot of black smoke for a second then the turbo spools and it's normal.
Today though I turned a corner and began to accelerate after but I had no power at all it shot out an un manageable amount of black smoke mixed with very little white as I pressed the pedal. I put the pedal to the floor and the rpm were up to 2000 still no power I out it in tow hail still pedal to floor and now power! At this point I pulled over and called my dad figuring the truck wouldn't move anymore but I got no answer so I tried to go again seeing how ideas almost and and the truck worked fine small amount of lag but it ran made boost and worked until I got home. What could it be? I've heard maybe my turbo is bad maybe my egr valve but I'm just not sure.

2001 Hyundai Elantra GLS ... I don't know what is going on with my car. When I start it, put it in gear and try to pull out, it feels like there is a loss of power. A few seconds later, the power returns . I can push my foot down, and the engine doesn't rev, but then it's like all of a sudden the engine realizes I have my foot down and takes off.

Mine is 2006 with 130k miles. Just replaced fuel filter, air filter, cleaned air flow sensor and cleaned the injectors. The car still feels slow and it seems to eat more fuel than before. The spark plugs and the wires seems to be ok. No warning or error on dash is displayed.
When push the accelerator it takes a while to respond starting from stop position, and when the car is moving and try go faster it feels like lazy so I have remove the feet of the pedal and push it again so it respond quickly.
