I've been experiencing ENGINE RPM FLUCTUATION on cold starts. I took it into the dealer and they found an update available for the ECU and reprogrammed the ECU.
2009 Santa Fe ?
So far it appears to have corrected the RPM Fluctuation on a cold start... I see TSB 10-FL-010 cover this but also suggests to replace the Throttle Position Sensor which wasn't done on my vehicle.
I have a 2009 Santa Fe Limited with the Infinity sound system.
Last night driving home there was a split-second power pop/fluctuation in my center console. The lights and sound turned off for a split-second. I didn't notice if this also happened with my driving console or exterior lighting system, but the wife seems to think that it was only the centre console.
Just had my original transmission replaced at 96000km. My new transmission has a quirk that happens from time to time when you start the vehicle there is a "thud". It varies from small to loud and only happens the second the engine starts. I have noted that it is worse when the car is parked on a hill and the parking brake is engaged before the car is put in park. My only idea is a problem the the parking mechanism or pawl as its called. The dealer won't even admit there is a problem. I've never had worse dealer service with any automaker.
View 3 RepliesMy car is an 08 AWD 3.3 I am noticing the engine will do a slight rev up, down, up, down when cold almost daily when I leave work in the afternoons.
I removed the airbox and intake tubing, cleaned the throttle body with TB cleaner and mass air sensor with electronics cleaner. I also used about half of a bottle of seafoam in one of the vacuum lines to the engine, and the other half in the fuel tank. Also ran some Chevron fuel system cleaner in the fuel tank. Nothing seemed to make a difference. It still persists.
It's noticeable the most in neutral, you can watch the tach rev up from 800 rpm to about 1100 and back down repeatedly. If the car is in drive and the brake is lightly applied, it will want to move when its revving up.
Twice this week our 2009 SantaFe (3.3l) had a squeal from the engine upon cold startup. The first time it was very cold (-20C or so) and this was louder and longer than the second time (-10C or so). The squeal lasted only a few seconds and trailed off to nothing. Each time the heater controls were set on defrost (fyi). In order of likely suspects, I suspect one of the following:
-compressor engaging and causing sudden increase in resistance on the belt or compressor engagement clutch noisy
-idler pulley for some reason causing belt to slip at first, but don't suspect idler bearing as noise disappears right away
-belt slippage due to resistance somewhere else--e.g. water pump or alternator.
This may not happen when I take the vehicle in for its next scheduled maintenance as by then the weather will likely be warmer. This has 76000 km on the clock.
Having an issue with my 2007 Santa Fe 3.3L. When the engine is cold, been sitting for a few hours not when the temp outside is cold, it takes about 5 to 8 cranks before the engine will fire. I can then shut it off immediately and start it again and it will fire right up.
I currently have the P0464, P0463 and P2068 check engine error codes for the fuel level sensor units. I don't really know if these are directly related as I've had them for about 6 months and the starting issue has just shown up the last month or so. Plus, I would assume these should only be related to sending fuel level information to the fuel gauge. Either way, I'm still leaning toward a fuel delivery issue since it only has a hard time starting when the car has been sitting for a few hours. I don't know if maybe it's the fuel pump or a electrical component. If it's the fuel pump, I'd like to do that when I take care of the sending units so I don't have to go back in. I've tried turning the car to the 'on" position for about 10 seconds without starting it to see if I could get the pump to load the line, if that's the issue, but it doesn't seem to make a difference.
The battery is good. It tested 12.5v after sitting over night.
07 Santa Fe 3.3 with 155k miles has lifter noise all the time. Much more pronounced in cold weather upon start up when the engine is cold. These miles are mostly highway and I change oil every 5-6k with Citgo synthetic blend. Is this just normal wear or could the engine be getting gummed up? I was thinking about treating the engine with some Marvel or Rislone but I really don't like putting solvents in my crankcase.

View 3 RepliesHow to fix a speedometer reading fluctuation? When I am driving about 45 mph the speedometer will drop to zero (RPM does not change) and then will bounce. Some times the speedometer will remain at zero other times it will bounce back to indicating speed.
View 2 RepliesWhen I drive my 2010 santa fe. I get a noise that sounds like i have a flat tire in the back. It is intermittent and starts at any speeds. But when you stop the vehicle and start again the noise is gone. The mechanics at Hyundai replace replace a part for the all wheel drive but that did not fix the problem.
View 1 RepliesMy 2007 es350 77k miles. Heater starts to get warm and then it blows cold air. What could cause this.
View 8 Replies07 That has 138K miles. The noise starts around 10 minutes of driving. Th engine sounds like a diesel engine. The noise has lasted 5 to 10 minutes. Then shut it off and it won't return til the next morning...Same thing. THIS DOES NOT SEEM TO OCCUR on start-up. It has to run for about 10 minutes (moving) or so. Changed out the water pump. The noise is coming from near or behind the water pump.
My mechanic is stumped but he pretty much thinks it's coming from behind the water pump. That leads me to believe it's the timing chains/tensioner's etc. But the time it starts up is throwing me off. When it is cold I think I can hear a little clacking that shuts off quickly after oil pressure gets going but it's not really the same sound that were are hearing when moving and the crazy sound starts and it is LOUD!
We were thinking it was the timing belt tensioner however, it is not behaving like it should.
2007 Silverado 1500 ... Thought i had the dreaded cold start piston slap but discovered it was left side cat rattling internally on cold starts only makes noise for about 30 seconds. head pipe has been down 3 times due to transmission issues.. my question is if i gut the cats out will it damage anything or throw out codes ?I understand legal the ramifications ,just didn't want it to break up and plug up.
View 3 RepliesI have a 2007 Santa Fe GLS AWD that has a rear driver side tire problem. It starts after roughly 10 minutes of driving as a slight squeal. It starts at around 20mph and will quit when I reach 40mph. The longer I drive, the louder it gets to a point where it is almost constant between 20-40mph. It stops when I apply the brakes or when I turn slightly to the left or right. Also, if I stop and turn the car off it takes 5-10 minutes for the squealing to start again. There is a smell of hot metal and sweet smell coming from the area.
I had the rear brakes and rotors replaced 12,000 miles ago, and them checked at my local Hyundai dealer when I first noticed the squeal and the mechanic said the brakes and rotors in the rear did not need replacing. What it could be?
I have a 96' ranger that has been missing quite regularly. The vehicle has over 200,000 miles on it, but has been taken care of regularly by me since 75,000.
Problem: When I start the vehicle, the engine takes a little bit to find the idle. It spits and fumbles around some until it finds a somewhat rough idle. Often, when I first start driving in the morning, the vehicle really jumps around due to misfiring. Even after running smoothly for awhile, the vehicle with sporadically misfire with no rhyme or reason. This is particularly true when climbing a grade. When sitting at a red light and idleing in gear, you can definitely feel the truck shaking from side to side. Also, when idling in gear, the battery gauge on the dash fluctuates, but when the vehicle is in park the battery gauge doesn't fluctuate...it just idles a little rough.
I had the Ranger to a garage and had them check the battery and alternator connections and ground to try and figure out what is making the battery gauge fluctuate...alternator and battery checked out...no diagnosis for fluctuation.
I replaced all plugs and wires and also checked the coil pack. One of the coils (#6) had some build-up in the top. I cleaned it out and replaced all the plug wires and everything snapped in place and fit fine.
The garage did tell me that an error code came up with the EGR valve and or sensor. They didn't seem to concerned about it. Do the EGR valve could be the cause of all the stuttering and misfiring going on with the ranger? I really don't know where else to look. Maybe replace the coil pack?
The oil light on my 2005 Chryler Town & Country comes on when started when it is cold outside. It stays on until I turn the key off and restart, then it goes out and does not come back on. My mechanic cannot find anything wrong. This only happens in cold weather, not in the summer.
View 10 RepliesI have a 2000 honda civic with 120,000 miles on it. recently, on cold starts (when i haven't turned the engine for a day) i've noticed a rapid vibrating or rattling noise about 30 seconds or so after i've turned the ignition. this noise lasts for maybe 15 to 20 seconds then it goes away, presumably as the engine has warmed a little.
I do drive a lot, and during the day even after the car has not been running for a few hours this noise doesn't occur. Only happens on the cold starts. I hope it's nothing major. I've attached a video with the sound. about 30 seconds into the video you will hear the noise kick in. (if the video doesn't show below here is the youtube link: [URL] ....
Bought 2009 santa fe new [3.3]. after cold start up tac is moving up and down and it seems to be missing. After temp is reached tac is steady but there still seem to be a hesitation when driving. 21,000 miles on vehicle. could it be a bad tbs?
View 4 RepliesI just bought a 2010 Santa Fe. All seems fine except that when the car is cold it goes into R harshly (with a bump and a small delay)and also is a little bit irregular in normal gear. I'm used to have cars with transmission problems unfortunately and happily it's nothing like that but I'd really finally like to have a vehicle without any tranny issues.

View 2 RepliesI have a 2007 3.3 with 42K miles on it and the AC just started passing air that's not quite as cold as it used to be. When its at idle I would say its a mild cold and then when driving its the same mild cold but with more force. Understandably today is really the first hot, humid day of many to come so I was wondering is there any good indication that its just low freon with a leak or the compressor is going or is there any adjustment to the belt in case its just slipping? I did it drive it for quite awhile and it never improved. I would hate to drive it more and ask for a bigger problem.
