Santa FE SM (2001-06) :: Won't Start After Spark Plug Change
I somehow managed to kill my 04 Santa Fe 3.5 while doing the dreaded spark plug change and looking for pinpointing and rectifying the problem.
A quick rundown of the car... My mom bought her new in late 03, decided to get a BMW X3 a couple of years ago. I bought her with 65k miles. I just recently had the timing belt replaced by a reputable shop at 79k (yes I know I let it go too long.) I just hit 80k and decided it was also time to do the plugs as I had noticed a decrease in performance and gas mileage of late. Other than the recent dip in performance the car has been extremely reliable and has had no previous issues.
I researched as much as I could knowing that the 3.5 isn't the easiest engine to work on. I bought the recommended Champion plugs that came in the car from the factory as well as the oem Hyundai wires. I also replaced the plenum gasket.
I took my time replacing everything but despite my best efforts, I accidentally cracked the plastic on the radiator reaching over to the back bolts on the plenum. Other than that mishap, the only other issues was the #5 plug sticking which finally came loose after some begging and pleading to the car Gods. Unfortunately, my begging and pleading was enough for them to allow the car to start.
After reading a thread on here, I believe the problem is that I removed the TPS sensor to get to the bolts on the EGR valve, I know now that this was a big mistake. I checked and double checked every connector and can not find one that was missed or disconnected. The car would try to start but would not crank over. I was unable to get any OBD2 codes from my code scanner.
I decided to try a TB from a junkyard and swap it on to see if that was the issue. After swapping it on, the car started and ran like crap for about 15 seconds and stalled out. I was however able to pull some codes in this short time.
The codes I received are:
P0102: Mass Airflow Circuit Low Input.
P110 & P1172: ETS Improper Motor Current.
P1192: ETS Limp home - Target Follow Malfunction.
P2127: Throttle Pedal Position Sensor "E" Circuit. Accelerator Position Sensor 2 Voltage Too Low.
I'm not sure if these codes are left over from before I swapped out the TB or not. I reset the codes after I wrote them down and researched them to see if they reappeared but the car will not start again so I can't get the codes to reappear.
Santa FE SM (2001-06) :: 2003 Jerks At Highway Speeds
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

While driving at between 20-45 MPH in warm weather only IDEAL SPEED IS 38-42 .. At times the car jerks forward and downward like, even slowing down at red light: Seems like the whole problem is coming from transmission! (Sensors)? The car is cursed. Example:
1- The symptom seems like your driving in drive position then all of sudden it shifts to low gear
2- When driving normal then it seems like the car shifts to neutral and the RPMs shoot up to 3-4
3- Sometimes when stopped the steering wheel shakes bad.
The car runs normal in winter time? Doesn't do it everyday.

I have a 2003 Santa Fe 2.4L (automatic) with 200,000 miles. Auto shop is recommending I change my transmission fluid. I've heard that changing the transmission fluid on a high-mileage vehicle is potentially dangerous. I haven't noticed any symptoms of "bad" transmission fluid.

2004 Santa Fe, 2.7 L V6. The oil was changed approx 5-7k miles ago (not really sure as I bought it from someone else) and I just changed it today. There's a new knocking noise in the engine. I used normal castrol GTX oil, 5w-30.
I drove it about 20 miles and the noise is still being made, so it's not a circulation problem.
Santa FE SM (2001-06) :: Trans Fluid Change Interval

I need to take a trip....round trip will be about 4600 miles I probably have less than 1500 on the current fluid now.. and before that had changed it 2 other times within 1000 about 8 mo. apart just to rotate the fluid. I am planning to do it as soon as i get back.

I've had the plug wire for my #4 cylinder burn out twice in the last 6 months. The car started running like crap and threw a CEL, the code was for a number #4 cylinder misfire. When I pulled the wire it has obvious signs of being burned out, like white powder and burn spots near the base of the wire where it goes over the plug. The plug and coil both look normal. No issues with the other cylinders. What could cause it?
This is on my '05 Santa Fe, 2.7l, FWD auto, with 180k miles

Purchased this car new. 2008 GLS w/ V6 2.7L engine. Wife's car, so I rarely drive it. She's complained for a month about an intermittent issue with the jar "jerking", usually during slow speeds.
I felt it for the first time myself. Was halfway through a pretty tight curve at around 20 MPH, starting to slowly accelerate when I felt a definitive lurch. might have been momentary loss of acceleration, or transmission. Not sure which. No CEL thrown.
I did see another thread mentioning a 2007 with a similar issue, but that person had codes thrown that pointed to a Throttle position sensor and a need to reflash a transmission. Think I'm seeing the same situation, or would this be different ? Absent any CEL, I'm sure the dealer will not be able to find it....
Santa Fe (CM - 2007-12) :: 2010 - Engine Jerks When Driving Slowly
I bought a 2010 Hyundai Santa Fe 3.5L and noticed the engine would jerk really bad. It felt like the engine was going to jump out of the vehicle. I notice it does it when I turn it on in the morning and when I am driving slowly out my lane way the engine jerks. I have dealt with this problem since last year and they have already replaced the transmission which has done nothing. I took it back to the dealership and the service manager told me that he has already had 4 of the same vehicles come in with the same problem and they realized that they had to re-set the computer in the engine so that the transmission computer and the engine computer are on the same page that they talk to each other so to speak. Since they re-set the computer we have had the vehicle back a week today and this morning the car jerked again. I am tired of constantly taking this vehicle in and being told they have a solution and then it is not fixed. How am I supposed to sell a vehicle to someone when it feels like you are being lifted out of your seat because of the JERKING!!!!!

My 2007 Sante Fe had problem this week. Took 6 attempts to start engine, then ran smoothly the rest of the night. The check engine light came on while trying to start vehicle.
Next day I changed the spark plugs but now find that the vehicle jerks when idling. Runs fine when going but jerks and bucks at stop lights and stop signs. Just added fuel injection cleaner to see if that may support the situation.
Engine light has come back on again since resetting. I have read several suggestions on internet regarding leak in vacuum line, Coil Pack damage due to faulty hose, even faulty 02 sensor.
