i took th car to hyundai dealer. they checked transmission operation, fluid level and condition. they are all correctly. checked car for current data and fault codes, found to be all correct. then we did a test drivind, the noise still there, it's more worse the car was driving on up hilly road. hyundai dealer told me the car is pinging poss, due to poor fuel. suggest a refill of premium fuel.i always use normal unleaded petrol. i don't know why? please give me a answer.
Thank you very much

1.The vehicle accelerate is ok from stop.
2.When noise came, the vehicle accelerate is poor at driving 60km/h.
3.When noise came,the transmission shift is poor around 60km/h.
4.Engine rpm's go high than normal, but vehicle accererate is poor around 60km/h when the noise came.
5.when noise came, if rpm is high, the noise is high . if rpm is low , the noise is low. When the vehicle'speed reached around 70--80km/h, the noise is low-than before.
6.traction control and abs lamps are not on.
Thank you very much for your help!!!------------------------------------------

I have a 2004 Santa Fe, auto, V6. It's traveled only 26k.Everyday i start the car, it's running alright. but after the car is running about 20 mins, the car getting hotter, when i press accelerator pedal, speed is raiseing very slowly, it also have some noise like " ke , ke, ke...." from bottom of the car,if release the accelerate padel, the noise gone. it's more worse when the car go up on hilly road, it's slow than a small car.
Please tell me what problem are ? Thank you very much!!!

Based on your description, it sounds like the engine may be misfiring. Is your check engine on or flashing?
Ordinarily, I'd recommend checking the secondary ignition components in the event of a misfire, but your vehicle is still within the warranty period. You should take it to the dealer and let them investigate.
-----Answer-----
A misfire should turn the check engine lamp on or make it flash. So I doubt that's your problem.
So far, I don't have a good mental picture as to what your car is doing. The following may help me understand. When the problem is occurring:
1. Does the vehicle accelerate poorly from a stop?
2. Does the vehcile accelerate poorly when driving 45mph or more?
3. Does the transmission shift normally?
4. Do the engine rpm's go abnormally high when accelerating?
5. Can you tell if the noise varies with the engine rpm or with the vehicle speed?
6. Do your traction control or abs lamps come on when the condition is occurring?
Without being able to determine what sort of problem you have, it's difficult to say whether it will damage the car. I'd recommend erring on the side of caution and taking the vehicle to the dealer to be checked.
-----Answer-----
If the engine rpm's are higher than normal, your transmission is probably slipping. Check your transmission fluid level and ensure it's okay. If the problem persists with the proper fluid level, you may need major transmission repairs.
-----Answer-----
It's doubtful this is the cause of the problem, but you should start with making sure the fluid level is correct.
When you checked the fluid level:
Was the engine running?
How long had it been since the vehicle was last driven?
How long had the vehicle been driven on the last trip?
What position was the transmission gearshift in?

I'm not sure what country you're in or how the fuel grades are computed there. In the U.S., all Hyundai vehicles are designed for 87 Octane (regular unleaded).
If you're getting a normal level of spark knock, you shouldn't have any noticeable power loss. Was there a lack of power on the test drive at the dealer?
A little spark knock briefly (no more than 1 second) when depressing the accelerator pedal isn't abnormal. If that's what you have, increasing the fuel octane may be detrimental. Higher octane fuels burn slower.
But if you've got heavy or lengthy spark knock, the dealer should be investigating why this is occurring. Excessive combustion chamber temperatures, lean mixtures, overadvanced ignition timing, or a faulty knock sensor could cause this issue.
Out of curiosity, what size V6 engine do you have?
AnswerIf the problem lessens with higher octane fuel, then I'd expect you're experiencing what's called spark knock. On your car, you should be primarily interested in verifying that the engine runs at normal operating temperature (not excessively high), and that your knock sensors are operating properly. You may also have enough carbon deposits to have reduced the effective size of the combustion chamber. In that case, the problem can be addressed with top engine cleaner. I don't know whether it's available in Australia, but GM makes an excellent top engine cleaner that's available at dealers in the U.S. The carboning may be considered a maintenance issue and as such may not be covered under your warranty.
I'm not familiar with the engine management systems in Australia and don't know how comparable they are with those in the U.S. Many of the things I've mentioned will cause a check engine lamp to illuminate on U.S. vehicles, but the diagnostic parameters may be different in Australia.
One solution would be to continue driving on 93 octane. If you don't want to do that, you'll probably need to continue further with the dealer. If the dealer isn't giving you satisfaction, you should perhaps try another dealer or try calling Hyundai Customer Assistance (if such a thing exists in Australia).
