MY 2003 Santa Fe is fwd with the 3.5 v6. While under normal conditions, the engine lost power and began "chugging" and "bucking". There was also a belt slipping "whine" associated with this problem. The problem continued for about two minutes, then corrected itself, and I was able to drive normally.
View 1 RepliesI have recently picked up an older F350 2WD 7.3 DRW Lariat. the price was right higher miles but hey it is a 7.3, overall in very good shape.
So the issue at hand is the truck runs great most of the time and puttering around at city speeds you would never know there is any issue;
Get the truck out on the highway set the cruse at 70 to 72 and if you hit a rise in the road or other reason to slightly accelerate the truck chugs and bucks. For lack of a better description it goes chug chug chug, if you accelerate harder to downshift it goes away or if you back off the throttle it goes away. This happens with cruse on or off, a steady foot on the pedal will cause this as well.
I have also noticed that when you let off the throttle the sound the truck makes de-fueling is just very different and "off" sounding . Not sure how to describe it but it sounds funky ... clearly not right when compared to other 7.3 or my 6.0 truck.
What I have done, :
1. Had the truck scanned with an AE and a snap-on scanner both show no codes ran injector tests no contribution errors, not even in # 8.
2. Changed fuel filter
3. Changed Oil and Filters ( tried both full synthetic Rotella and Dino oil looking for a difference )
4. Cleaned out the fuel filter housing just in case.
5. Confirmed injector O-Rings are not leaking
This feels like a fuel issue, my next thought was start looking at fuel pressure under load at speed to see if there was a drop when this is happening ?
Is there a way to test fuel pumps in this truck ? Maybe a clogged pick-up screen ? Where do I start looking next ? I have reasonable mechanical skills but don't know this motor very well, this doesn't seem like a CPS issue..
Title says it all. I was on my way to grab dinner, stopped at a light and heard it. At first, I thought it was a car next to me. Then it kept on going, and my CEL came on. I pulled over, shut off the car, popped the hood.
Temp normal, no smoke, restarted and watched the engine. Rough idle, and it appears to be bucking. Sounds like belt noise, not sure what is going on..
Long story short is, I replaced my 2007 Santa Fe's serpentine belt and it still squeals for some time after we start the vehicle (then stops) ... but more importantly I *think* its still slipping if we're driving during rain or on very wet roads.
Long story long is ... the problem appeared as loss of power steering and air conditioning when driving during rain. Took it to the dealer and they suggested to replace the serpentine belt, replace the shroud (plastic) that covers the belt, and replace the timing belt. As we have 36k miles on it, no one I talked to understood the timing belt suggestion. I see though perhaps its just because the car is 4 years old? The shroud the dealer claimed was cracked and may be letting water in on to the belt. However, they completely removed it and did not replace it so I was not able to inspect this myself (wife took the car in for the appointment).
I bought the new belt and put it on. The squeaking was gone but as soon as I hit rain again, the slipping was back as bad as before (and we'd lose power steering / air conditioning same as before). I had a 1.5 hour drive in rain where the belt was slipping almost nonstop; constant back and forth between catching and slipping.
When the replacement shroud came in I thought that might solve the problem - keeping moisture off the belt. However with that in place I'm afraid there is still some slippage as I've noticed some dashboard lights come on during brief heavy rain. Also the initial squeaking is back when we start the car.
I have 130K miles on my Santa Fe. I just replaced the timing belt without the water pump being replaced. Picked it up from the mechanic and the check engine light was on and it was idling very rough. Left it there for him to recheck. He said maybe he didn't plug in the Cam Sensor all the way or at all. Next day he called me and said that the cam sensor was bad and he replaced it for free. Picked up the vehicle and the idle was a little rough but got worse on the ride home.
View 1 RepliesI replaced my GF's water pump, timing belt, tensioner and roller on her 05 Elantra. WHen I started the car up I can hear a loud whine from the belt.
Everwhere I searched I read that it's too tight.
But in this video: [URL] ....
At around 9:11, when the guy starts the car it's the same exact whine? Is this normal or something with a brand new belt? Or did he tighten it too much? Or is it because her timing belt covers are missing the rubber grommets, and there is a HOLE in the side of one of them. So am i getting the full brunt force of the timing belt?
My 2003 Sante Fe has developed a rattling sound in the engine. The oil level has been good. I took it to a dealer for diagnoses and they told me that the engine was gunked up and the timing "chain" tensioner couldn't move to keep it tight and it was rattling. They put some engine cleaner in and changed the oil and wanted me back in 500 to clean it again. I did that again, but the rattle is still there. It gets a little quieter after I have driven it for a while.
My question is doesn't the Sante Fe have a timing belt? If that is the case what do you think the rattle is?
I recently replaced timing belt and balance belt on my 2004 santa fe 2.4l and now the engine runs like crap and shakes badly. I went over all timing marks again and again and I am at a loss.
View 9 RepliesWell, two years after I replaced the pump bearing and the power steering is acting up like the belt is slipping. Sometimes it works fine, sometimes the steering gets jerky and hard.
The fluid level was fine, but I changed out the old stuff anyway, the belt is fine and not loose. I also pulled the pump apart to inspect it and it still looks as good as new.
When it acts up at a stop, it will squeal, but like I said, the belt is not loose. It's almost as if the rack is bottoming out against the bump stop (it's not) or the valve that lets excess pressure is dumping pressure randomly.
I took the valve apart with the pump and it looks fine, no scratches. Do the rack or valve go bad? If so, what was that like and could my rack have a seal leaking inside?
I just changed the alternator in my 02 2.7l and now it is acting like it's not charging the battery. It's bucking and popping like before I changed it. I had to jump the battery and it drove fine for a while then I lost all power and no dash lights or anything. All the warning lights came on also. The headlights were dim and the car was bogging and bucking. I checked the ground and the battery is about 2 years old. Tomorrow I am going to get the battery checked and scan for codes. I also just replaced the starter a month ago. What could be the cause of this?
View 9 RepliesI've got a 2006 2.4L manual trans - runs great, except every once in a while, at low r.p.m., it surges or bucks. Sometimes, I press the gas and not much happens for a second then it takes off.
Other - much more rare - times it bucks like a jackrabbit a few times until I let off the gas, start over, and it accelerates fine. And most randomly of all, the idle seems erratic - not rough or jumping all over the place, but not always at the exact same r.p.m. Or if I come to a stop, the idle will drop really low for a second, then "wake back up" and idle normally.
But then most often of all, it drives normally. Anyway, step one was to run a tank of premium gas with a good injector cleaner. Which I'm doing now. Wondering if it's spark plug wires?
No "check engine light" at any point during this. All maintenance up to date; recent spark plugs; 187,000 km.
1996 Mazda Protege, 133224 miles, mostly city driving, automatic transmission
This weekend the car started bucking, problems shifting into gear, chugging, slight odor of oil, very slow moving. This morning (in my pf's) I ran the Scan OBDII and there were no error messages. I checked fluids and they were fine.
Possible problems? I am at a decision point, get rid of the car (needs tires, front brakes and it burns a bit of oil each month (1-2 cups) or fix it.
I'm in the middle of doing a timing belt and as I was slipping the new belt on my crankshaft moved! To my horror my timing mark erased after I used some brake parts cleaner to blow off the area. What can I do to get that bolt back to TDC?

I have an 05 Jetta Wagon GLS 2.0 which has been amazingly resilient. I had the 100k check up done recently and everything still came up positive; the battery conked out at 120k; and I just recently replaced the stock head and tail lights out of proactiveness rather than them going out. But, I think I've run into an issue now. When I drive through a puddle (or otherwise get water significantly on the underside of the car) if I am running the AC at the same time the engine makes a squealing noise as though a belt is slipping due to the water. I presume is the case that a belt is slipping--and I imagine that is part of the reason it idles noisier than when it was new, but before my wife and I make a budget I'd see whether there are other options. As it is there are 130k miles on the car, it's a 5spd standard, and other than oil changes and the checks at 30, 60, and then 100k no real service has been done.
View 4 RepliesDrove the vehicle today (current at 156k miles) about 40 miles then came back home. Left again to run an errand. After coming out of the store and starting the car, a very pronounced 'whine' occurred. It kept whining for about 2 miles and with 3 blocks left to go, the whine suddenly stopped. No CEL appeared and the radiator temp was normal, oil level was fine and the pwr steering fluid in the reservoir was at the max level. I suspected it might be the p/s pump but, if so, why did the noise cease?
View 1 RepliesI will try to film the sound and post it later; but for now I have a 3.5L V6 AWD with 85k on it. i get grunting and groaning on colder mornings and sometimes a med pitched whine, more noticeable at higher speeds in town.
View 9 RepliesI've got what seems to be a fairly common problem in that my power steering on my 2001 SF gives off a steady whine. I've read in several posts that removing the power steering reservoir and either replacing it or cleaning out the screen solves the problem. I'm ready to give that a shot, but can't seem to figure out how to remove the part. There is a "tab" type of thing on the back of it, but it doesn't seem to do the trick. I'm admittedly no mechanic, but this seems like it should be relatively easy. How to remove the reservoir?
View 6 RepliesMy 2001 santa fe has recently had a new clutch fitted as the old one was slipping but, when towing our caravan at the weekend the clutch is playing up again but, this time the clutch is slipping at anything above 2500 rpm yet she is pulling fine below this rpm.
View 4 RepliesOk santa fe 2006 (facelift) clutch was slipping. We've put new clutch kit in it (thrust bearing; friction and pressure plate). We discovered it had already had the DMF concersion to single mass. So we ordered the single mass clutch kit for it and fitted. All back together, clutch won't disengage and allow you to put it in gear!!! So took it all apart again to check the fitting as the inspection hatch it just didnt appear all fingers on the pressure plate was being pulled.. all looked correct, thrust bearing snapped in to place as it should... we got box back on (making sure the lever entered the thrust bearing correctly) and still no luck. When you press the clutch you can pull the rubber on the slave cylinder back and the piston moves all the way to the circlip. There appears to be movement on the pressure plate in the box. At a complete loss.......... what could have happened?
View 3 RepliesThis has begun in the last few weeks on my '02 SF (which only has a couple of months left until it is retired )....
If I'm going anywhere between about 90-110 KM, I'll hear an odd high pitched whine. It sounds almost like microphone feedback, and I'm having a really hard time trying to find out where the sound is coming from. It is very subtle and comes and goes.
Twice now (and maybe a third time once I start my van again) we've had problems with the van chugging and then the service engine light blinking. Both times it happened in the past, we took it to a mechanic who said it needed a tune-up - new spark plugs, wires, etc. I'm curious as to why this keeps happening. Mileage is around 105K. It first happened last summer, second time was in December. Now it's March. What could cause this problem to repeat?
