Loss Of Power In 2009 Santa Fe Crdi

Hi,
We have had had our Santa Fe for a year, done 38000 km and love it.
A few weeks ago we started experiencing a pretty major problem with it though so i just wanted to know if anyone here has experienced or knows about the same problem.
The car will start up and drive around town fine but as soon as the engine is under load at highway speeds or driving up a hill it loses all power.
In Automatic when this happens the gear will drop back to third. You can switch it over to manual mode and slowly accelerate back up to around 80-90km/hour with your foot flat to the floor but the rpm don't get above around 2000 to 3000.
If you stop and turn the engine off for a minute or so, when you start again everything will appear to back to normal but after another minute or two the problem will be back.
The engine malfunction light comes on and sometime it's flashing but at other times it's constant.
The car's been in at our local Hyundai dealer for a week but at this stage they still can't quite figure out the exact cause of the problem.
The code they pulled out suggested it was the exhaust particulate filter (apparently quite an expensive part) so they replaced that but it didn't fix it.
They've also replaced the fuel filter and some temperature sensors that are part of the particulate filter apparently but still no joy.
I'm just glad Hyundai offer a 5 year/unlimited km warranty in Australia because it looks like it could be quite an expensive fix at this stage.
Anyone have any ideas?

That happened to me 2 weeks ago. I brought it to the the dealer and they run some diagnostics. The sensor near the intercooler( idont which one exactly) became dirty and was not sending the correct signal to the ecu. They cleaned it up and now its back to normal. Mine is a 2.2 crdi. Hopes this helps.

Hello!

Problem in Belgium is that almost everybody wants to buy a diesel but lots of people don't drive enough km's to keep the engine healthy. First things to fail are the EGR valve and the particle filtre. Common problem here, first they trie to clean the Valve by removing the exhaust load inside and if not ok, they replace the valve. Some non-official dealers trie to 'lock' the valve in closed position to bypass the valve and blow the exhaust gas straight out.
My brother had the problem on his Seat Ibiza, his Saab 9-3 and now on his Hyundai Tucson, after 3 cars he begins to believe people are right that his next car should not be a diesel. He drives like 5 km's to his work and thats it. a diesel engine doesn't like that...
Hope your problem is found and fixed!

Hi Bart, thanks for your feedback. Its confirmed the egr valve. The dealer replaced the egr valve, cost me Brunei dollar 176 at 40% discount. The spring mechanism somehow has elongated. On the diesel engine running km's per trip, do you know the norm period for a single trip?and why diesel behave so? Also on locking the valve, will this affect the performance?

Welcome,
the EGR valve is an environmental thing to make the exhaust gas go back in for another filtering in the particle filter so the output is cleaner...
Nothing to do about it, try to keep it clean by driving in higher RPM from time to time. But if the valve becomes stuck, it better comes stuck closed so the exhaustgasses go straight out... but you can't tell without looking into the valve. Some cars give fault code when the valve is stuck, some don't, I don't know if the Santa fe does this, the Tucson doesn't show a dash warning but it can be seen with the examiner from the dealer.
Don't worry about it, things could be worse.... much worse!
Enjoy you Santa fe.

Greetz!

Lose of power SF 2.2 CRDI

I have the same problem with my car. After 1 year going in and out of the garage they offered me a new car. I have accepted this because they are not able to find the problem.
I will get my new car in 2 weeks and send them the link of this forum.
Hopefully they will read the comments and use this as a positive feedback to enable them to fix problems on there cars.

Thank you for the usefull information
