2004 Hyundai Santa Fe Loses Power in Very Cold Temps

For three years I have been battling with this same problem. I have changed the fuel filter, TPS sensor, air filter, battery, and alternator. Every year when the temperature reaches around 20 degrees, I lose acceleration and power. The check engine light comes on and I have to pull off to the side of the road. If I let the vehicle idle for 20 minutes and re-start the vehicle, usually the car will run great and I can reach my destination. Also, if the temperature reaches above 20 degrees while sitting, the car will run great. This only happens when the temperature reaches the 20 degree (Or colder) mark. I have never had any problems in warmer weather. Lastly, I have taken the vehicle in (Several times) to have the codes read. The codes have never given an absolute solution to the problem. Hence, why I am frustrated! Any help would be appreciated!

You may want to check your oxygen sensor and vacuum hoses. An OBD can help you identify the exact cause. Most auto store and garage should have one.

SOURCE: Will not start in cold weather. Starts great if

There is a 5th injector called the cold start injector, that is electrically controlled off the starter. You can easily unscrew it while still attached to hoses and wires, and watch it squirt. You can also verify it is getting voltage with a test light or meter. There is also a thermal timer for it that could be bad and preventing current from the starter.

SOURCE: 1989 Bronco II have replaced fuel

Is it the 2.8? I am just thinking of what cycles and would cause the engine to run bad. The fuel relay would not be the problem. Because if it doesn't close, then the engine does not run at all. The power distribution box is a possibility. But I am thinking about what you are saying the problem cycles. That is the strange thing. I think that the cycling has to do with pressure in the fuel tank. Have you tried changing the gas cap? That could be all that the problem is. But it could also be the vent in the fuel tank. The reason why I am thinking this is because the fuel tank builds pressure from the gas sloshing around and when it builds up too much pressure then it relieves. What do you think?

My Santa Fe loses exceleration, if you push on gas, it will not go any faster, usually about 20 miles. When diagnosed got code p2135. I was told there was a recall by hyundai for this. Is this right


Hello, There is not a recall for this issue,but there is a TSB (technical safety bulletin) by Hyundai for this issue that you are having with your vehicle for the code that was set. What this consists of is replacement of the throttle position sensor and performing an ECU software upgrade for the vehicles computer. The process usually takes about 45 minutes to an hour to perform at a Hyundai service department. If you are the original owner of the vehicle or it has less than 60,000 miles, this repair procedure is no cost to the owner. Hope this info helps. Gabe

Where is the trans filter located on my 2WD 04 hyundai santa fe?


The 2004 Santa Fe transmission doesn't have a serviceable filter. There's one deep inside the transmission, but the transmission needs to be removed and disassembled to get to it. The only time that filter would be replaced is if the transmission were overhauled. This is the answer I found online, and after trying to change the filter on a 2002 Santa Fe.

How can I change the fuel filter in my Hyundai Santa Fe 2004?


You simply locate where it's installed. Loosen and remove fuel hose clamps first. Plug any fuel hose ends with bolts of appropriate sizes. Remove the bolts and nuts holding the filter to the engine.
Replace filter with new one, and bolt to the frame. Connect back the hoses. Hint: its good practice to disconnect the negative post of the battery before starting this job.
