I notice that recently my Santa Fe does not run over 3.000 RPM in highway. Motor goes to close 3.000 RPM but does not shift to next speed and it feels as a lack of power, especially when uphill. Stopping, turning engine off and then on again seams to solve this problem, everything runs ok but suddenly the problem appears again.
My Hyundai is a 2007 New Santa Fe CRDI 2.2 (Diesel engine), automatic.
I was driving home on the highway doing about 60 mph in rush hour traffic the other night when it completely stalled out. When I started the car as I left work I noticed the engine noise was louder than normal but was in a hurry to get home. I was driving and noticed a change in the way the car was riding almost like a hiccup. I pressed the gas pedal to the floor and the car continued to decrease speed. I jumped off the highway on the next exit and the car slowed as I pulled on the shoulder and stopped.
As I stopped and put the car into park the battery, oil and check engine light came on. My headlights were still on as was the radio but the car would not restart. It was dark, raining and about 35 degrees outside. The local highway assistance showed up about 20 minutes later and gave me a battery jump. The jump lasted for about one mile down the road again and then died. The motorist assistance employee said that my belts were not turning so he thought it was my alternator.
My car was towed and kept in the shop for 3 days, no error codes, started right up and no problem they can find with alternator, tensioner, belts, or battery. The week prior I had my entire fuel system replaced as my gas gauge had stopped reading. The shop checked my fuel pump and did not find any errors. I don't know what else to look at and the shop is out of options...they have driven it repeatedly and cannot find anything. I have read on many threads about the crankshaft position sensor. Could this be the issue?
I have a 2007 Santa Fe with the 2.7L engine and 62K miles. At 65-70 mph I have a very noticeable miss. The check engine light has not come on and a scan at a Parts House shows no trouble codes.
View 15 RepliesI 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?
I'm noticing more and more on the highway when i accelerate that my car seems to pull to one side then when it shifts it snaps back. I'm not really sure if I'm even describing a transmission issue or a power steering issue. Basically, it just seems to pull and snap back fairly strongly, enough to cause a slight swerve as it shifts during acceleration. Where to start on something like this? (no error codes or check engine lights. Also no vibrations or other sounds).
View 11 RepliesI was driving down the highway when I had this loud bang and twang, after inspecting the car I realized it was the left rear seat belt that was broken. The seat belt fails to retract and cannot be pulled. I'm guessing the retractor is the fault.
View 2 RepliesOur FWD Santa Fe Limited had a very noticeable vibration that started around 60mph. Oddly, the vibration will sometimes come and go while cruising at a constant speed on the highway. We went about 30k miles before we had time to get it into the shop.
I asked them to rotate and balance the tires and the vibration was noticeably reduced...initially. Now it's back!
The car has ~65k miles. All 4 Kumho tires match and I believe are original from the factory. I have kept all tires inflated properly.
Our car has the optional 18" wheels. Is it common for these to bend? What else could be the cause here?
I have a 2010 Santa Fe AWD, I notice that when I apply the brakes at 100 KM or higher I hear a 'thumping' noise, the noise is hard to describe, thumping is the best I could come up with, the noise goes away once the vehicle is down to 80 KM, why this is?
View 7 RepliesWe 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.
About 4 months ago, I had the battery replaced since the car was not starting easily and they said voltage was not good. They also shimmed the ignition coil at the same time. I thought it was a bit early for a new battery but ok.
Last Friday I started getting a flashing battery light on the console but no other issues. Thought I would bring it in Monday.
Sunday I was driving on the highway and all warning lights came on, flashing, console died then came back on with a bunch of warning lights and then the car died. I managed to get off the highway with about 10% power and park in a lot. Car would not start once I turned it off, click, click, click, click like no power etc but rest of power in car seemed fine. Started fine Monday morning and I drove it to the dealership.
The dealership says the code was P2502 (Charging System Voltage). They are going to replace the Battery Sensor first and then if that doesn't work replace the Alternator.
I've got a couple of issues with a 2002, 2.7ltr v6 santa fe first off when taking off steady the car runs fine but taking off quickly it seems to lack power until it hits around 3000-3500rpm est then it takes off fine and all threw the upper rev range the auto seams sluggish but I'm not shore as I haven't driven another 2.7ltr as a benchmark. No error codes are present.
The second issue I brought a new keyless remote for the car and looked up a thread on how to program this they had reference to a set switch behind the fuse box behind the lower dash panel I went looking and found what I think is the remote receiver it has what is like a antenna cable plugged into it but no set-off switch at all is there any way to get this new remote programed or will it have to be done threw dealer or is there something I would be missing?
I have had the Santa Fe back and forth to the garage no power. We where driving it and all a sudden dropped power can't rev motor over 3000 rpm. Garage said they fixed it with dry gas and more gasoline b/c it was "low" between 1/4 and empty?

View 9 Replies2002 Santa Fe 2.7L AWD automatic
She was on the highway this afternoon and was accelerating to merge in with traffic. Apparently the car just reved up without actually accelerating. She said it felt like she was in neutral. I've driven the car a few times over the last week and it has been running perfectly - No hesitation anywhere at any speed. There are no CELs (yet). It is probably worth mentioning that it has been raining HEAVILY here for the last 24-hours and I would not be the least bit surprised if she hit a few puddles on the way. I can just about guarantee the CPS has never been changed and am suspecting it may be a short in causing her problem.
My '04 Santa Fe (135K miles) has been doing this for a little while.
Between 65 - 75 MPH on the highway, under acceleration, I experience what I can only describe as a "shudder".
I don't believe it's a wheel balance issue, because if I'm coasting or maintaining that speed everything is stable.
Cruising down the highway, my 2001 Santa Fe engine suddenly cut out. Would crank, but not fire. Not hearing a sound from the back when I flipped on the key, suspected the fuel pump, which I replaced. No go.
I'd pressed the fuel pump reset switch under the hood - checked it again. Should the switch, when it's pressed, stay in a locked position, like when you do a reset on a GFCI electrical outlet? Or is it normal for it to have the up/down 'play' in it?
Also noticed a strange buzzing on the other side of the engine compartment -- was the unit (don't know what it's called) that the throttle cable feeds into - hooks onto a pulley. The buzzing was intermittent and inconsistent, but it was happening with just the power switch on.
Oh, and did replace the fuel pump fuse, too. While it's at 280.000 miles, not quite ready to give up on 'er yet!
We have an '03 Santa Fe (2.4L). We are the original owners.
About 18 months ago, one of our Ignition Coils cracked and caused a misfire when then engine was under load. I replaced the coil, wires, and plugs myself at that time.
Since that time, we have experienced intermittent engine jerking while at highway speeds. There does not seem to be any pattern, and it does not happen every time we drive it.
I took it to the dealer who diagnosed a valve cover leak. They replaced the gasket, one ignition coil, wires and plugs. The problem still happened intermittently after that. I brought it back to the dealer, who diagnosed a valve guide/seat leak. Oil is getting into the cylinder and fouling the plug they say.
I could not afford the fix (and was very dissatisfied by the service I received) so the dealer recommended to change the plugs every 3 - 5K miles to get me through. I was told this on 03/31/09 (125695 miles). I replaced the plugs, wires, and BOTH coils again at that time.
Last week @ 130K miles the engine jerked again. I replaced all four plugs again Sunday morning, but the ones that I pulled were NOT look oil fouled. I showed them to a mechanic friend and the guy at the auto parts store. Both agreed that the spark plugs looked almost new. Sunday evening, while driving on the freeway, the car jerked again!
Since this happened again SO soon after changing the plugs, I really have a hard time believing the valve guide diagnosis. Some possibilities I have seen/heard:
- Crank position sensor or camshaft sensor (This was replaced at 78K miles along with the all of the belts)
- Clogged fuel filter
- Bad O2 sensor
- Vacuum leak from the hose that is between the throttle body and the engine casing
- The dealer's valve seat suggestion
My daughter was driving our 3.5L Santa Fe on the highway when it decelerated. Stepping on gas and no acceleration. She said she got a CEL and oil light. She was able to pull over to the side of highway and turned ignition off and on and she was able to drive off the highway and called me. She was about 120 miles from home. She said the cel light and check oil light were now off and I had here check the oil and it was at full.
I had her drive in the right hand lane without going over 60 and she made it home no problem. I took it out for a drive and no issues. Do you think this is a crankshaft position sensor problem?
mileage is 170k - timing belt was replaced at 130k.
I bought a 2004 Hyundai Santa Fe 2.7L AWD about 5-6 months ago. It has close to 120,000 miles and has a terrible vibration at highway speeds. It starts around 55-60mph and gets increasingly worse as speed increases. The steering wheel originally vibrated quite violently, but after changing the "front axles" it resolved only the vibration in the steering wheel
I took it to a local shop we trust, they changed the "front axles", all spark plugs, ignition coils, timing belt, transmission fluid change, and a o2 sensor.
I changed out a serpentine belt, tensioner, and idler pulley (due to a squeak), another o2 sensor, and tried to change the transfer case + rear differentials fluid. I couldn't change them because the fill plug was very stuck... we used a propane torch and a large socket wrench.
Anyways, after the front axles were replaced, the steering wheel got significantly better, there is however some vibration through it. After they were replaced it did not fix the vibration shaking the whole car. I've noticed that when you let your foot off the accelerator all the way, the vibration stops. When you step on the accelerator again it starts shaking very bad, and then begins to get slightly better. The vibration has a rhythmic timing to it. It seems like it pulsates stronger, then softer every 1/2 second or so
Also I have had the wheels balanced 3 times. I doubt it's the tires, unless a tire is out of round. My rotors also do not seem to be warped. When I brake, there is no shaking/shimmying. I was wondering if it could be the engine mounts? This vibration is very annoying, since I have to drive long trips sometimes. Other than this problem I like this car and would love to see it fixed.
2003 Santa Fe - Loss of power while driving on highway. Dropped from 60 to 15 MPH in matter of seconds. Feels like a couple of cylinders (3.5 liter) are not working.
View 2 RepliesI have a 2004 2.7L V6 GLS Hyundai Santa Fe AWD that I purchased about a year ago. The car has about 114,000 miles on it I believe. My problem is that I have an annoying vibration at idle and at highway speeds of 60-65 mph. The vibration decreases somewhat towards 70 mph. The vibration at idle is usually present, but sometimes vanishes for no apparent reason. The car is very smooth below 55 mph, but when around 60-65 mph becomes quite violent at times. The side view mirrors shake very badly and the vibration can become tiresome.
Originally the shop believed that the front axles were the culprit and replaced them – this mitigated some vibration felt through the steering wheel, but not much of the vibration throughout the cabin. The wheels have been balanced 3 times, alignment checked, and wheels do not seem to be bent/dented. (The tires were road force balanced)
In addition I have also had the following work done:
-2 oxygen sensors replaced (both post-catalytic converter)
- 2 Catalytic converters (replaced to pass emissions)
-Timing Belt Replaced
-Serpentine Belt Replaced
-Idler Pulley and Auto-Tensioner Replaced
-Ignition Coils Replaced
-Spark Plugs Replaced
-Transmission Fluid Change
-Oil Changes
-1 Tire Replaced (Sidewall Blew Out) (Michelin LTX M/S2 Tire)
-Air Filter Changed
-Crankshaft Position Sensor Replaced (It was Corroded Away)
Why the car is vibrating so that the mechanics can check it out. One idea I have could be the engine mounts – this would explain the vibration at idle (in park). I drive about 10 hours a week on the highway at the speeds that cause this vibration.
