#1878 of 1931 Auto lock malfunction
Jul 19, 2011 (1:06 am)
I'm new to this website and forum, but I've got nowhere else to turn with this creepy problem. I have a 2001 (or) 2002 Hyundai Santa Fe... can't remember at this time. I bought it used at a not-so-professional "dealership" close to a year ago. Until now there have been zero problems with my vehicle and its functions.
About a week or so ago, I unlocked my car with my key fob (as usual) to retrieve something from my passenger side. Almost a split second later, my car locked itself back up. I had successfully unlocked all four doors and the hatchback before this had happened. At first I thought it was my imagination and let it go. Then a few days later I went to unlock my car to get in and the doors locked a few seconds later; it turns out it wasn't a one-time thing. I had told my Dad about this issue and he seemed stunned, to my suprise. He doesn't really have a clue about what this could be, or what the cause is. And I must say, he knows a lot about cars.
Soooo, I thought the problem was just a willy-nilly thing that happened on occassion, until it happened again today but this time while I was DRIVING! My vehicle is not programmed to lock when it reaches a certain speed. It only is supposed to automatically lock after the twenty seconds or so that I unlock it and don't open any doors, for safety. Today I had been driving for about three minutes and was at a steady speed of 55. All of a sudden my doors lock and it scared me half to death. It frightens me to think that my vehicle could lock itself at any moment, including while I am in it. Not a very good safety habit it has learned I must say.
Could this be a problem with my key fob or my electrical/mechanical system in my vehicle? I'd love to know so I can hopefully have this problem adressed and solved. Thank you for reading!
#1880 of 1931 2002 Sante Fe gone bad!

I have a 2002 Sante Fe and recently it has started making this loud ridiculous sound like as if the engine is about the explode, it wont accelerate when its making this sound and after a few miles of driving through the sound it just stops. Im also having a problem getting up to speed, if I come to a stop or try to accelerate quickly it really lags and takes about a mile or two to really get up to speed. It also makes this LOUD ticking sound when I first start my car and after its been driven a few miles that sound goes away. My Dad replaced the power steering pump thinking that was the problem but its just seems to get worse and worse every day! It has 145,000 miles on it, I bought it used 2 years ago with 100,000 and drive a long haul to work. Has anyone else had this problem or even heard of anything close to what I am explaining???

The 2004 Santa Fe has a 100K warranty on it if you kept up up scheduled maintenance. Mine acted similar to yours although it was running at almost no power. The shifting problem was transmission related and covered and it needed two manifolds. One was also part of the power train coverage but the more expensive manifold was about $1600. I also had a bad O2 sensor. The sensor and manifold cost about $2500 total. The manifold part was about $1100. I'd call other Hyundai service centers and see their prices. The catalytic convertor shouldn't affect the transmission not shifting.
Are you sure you aren't covered by your power train warranty?

I never had any responses or clues as to what may be causing my electrical troubles. They get worse as the weather gets hotter.

Ask them to show you the crack in the manifold. When they messed with the cables/linkage that traverses over the manifold, It is likely they did not reconnect them properly. This would cause your your vehicle to run at high rpms. Based on your reported issues and description of what the dealer said...I would be highly suspicious of their ethics and competence or both.
GET another diagnostics from a different unaffiliated source.

Check the FOB first. Use a small coin or flat-tip screw driver and gently pry open the Key Fob. There are two indentions along the side seam for this purpose. Once open, inspect the battery and button contact points for corrosion, dirt etc. Clean off any rust or debri. Slightly bend up the three battery contact prongs.
Remove the small circuit board from the rubber gasket/button piece. Clean the rubber piece thoroughly. Make sure there is no water or noticeable debri/dammage on the backside of the circuit board. There are two tiny contact switch buttons. Gently press them with your finger nail. They should make a soft click, if not, replace the Fob. Reassemble, and test.
#1885 of 1931 Need help figuring out what services are really needed.

Hello everyone today is my first time in this forum. I have a Santa Fe 2006 it has 48600 miles in it and I have to say that up until today the car has been great. It survived a head on collision 6 months ago and I think the car's structure helped out a lot in me not getting severly hurt.
But my question to all Santa Fe owners is this; How much meintenance do you give your cars?
Today I went for the 45000 meintenance service that cost me $435.00, I also got a list of recomendations from the mechanic that involves another $ 500.00. Services such as flushing the oil in the stearing wheel, cleaning fuel injectors, drive line fluid service and ihrutte service. Now, in this economy I can't afford all that work, I would like to know if anyone out there has done all of this work to there cars, the car is in good condition and hasn't have any problems. I think that the dealer is taking me for an expensive ride. If there are any mechanical sabbys out there please help me.

You can also check the Hyundai website for maintenance schedules. You can find that here:
I wouldn't bother doing anything other than what is on the list for your car's year and mileage since this is what is recommended by the manufacturer unless you are having a specific problem. I hope this can save you some time and money.
