#1164 of 1181 Intermitent lost of acceleration
Dec 08, 2012 (8:34 pm)
I just bought santa fe recently after driving home from the dealer, i parked the car in my drive way, on second day wont start. I also noticed a lost of power when driving, the engine is running but there is no response from the accelerator.The car was towed to hyundai but there was no error code on the system. They did so many cold start and the car started fine. I got the car back after a week with them on my way home lost of power to set off. I noticed that I have to put the gear in Neutral and rev the engine before the car will accelerate. I took the car to another garage same thing no code and they confirm it is not the gear box. Please, can anyone tell what the problem might be, because I love this car and I really want to enjoy driving it.

It's that STUPID fly-by-wire accelerator pedal. Step on the pedal, wait 1/2 second, then the car goes. Bring back the MECHANICAL connection from pedal to throttle body.

Do you have an awd model? How.many miles does it have?
The other member is correct about the drive by wire system. Especially on 4 cyl modes, dbw is very pronounce delay between throttle and the pedal sensor. Its not.much u.can .really,, besides get a v6 where more low torque is available. Another.issue u have against u is.the transmision, their units are very reluctant to downshifts, they are gear for economy.
The curb weight of the santa fe is somewhere over 4700 lbs. For.a four.banger its a tall order to accomplish good of the line acceleration.

For my car I had all the same issues and it took my dealer a year to figure out the problem, and I ended up calling Hyundai Canada to get satisfaction. They replaced the Throttle Positioning Sensor. I would start there and see if you get a fix that way. It should be covered under warranty.

thanks for the reply but I am still unable to find solution to the problem. I have decided to record the problem on video and place it on youtube. I will be happy if someone can have a look and advise on what to do regarding the problem.
After starting the car starts to smoke. This is the smoking video..

You've got a blown head gasket or a blown intake gasket. I'd lean more toward the head gasket, however. Get it fixed right away!
You'll destroy your engine if you don't repair it ASAP!

I'm having the same trouble with my 6 month old 2012 Sante Fe, only 12,500 miles. It has been to the dealership 2x in 10 days and the only thing they've done is to reset the ECM, which has not resolved the issue. The first time I was driving about 45MPH the check engine light went on and within 2 minutes the car suddenly lost power, the accelerator would not work and I had to roll to the side of the road. The second time this happened I was driving around 60MPH and again suddenly dropped power and had to pull off the road. In both instances turning the car on and off about 2-3 times cleared the issue (though the check engine light stayed on for about a day following the incident). However, I was able to drive normally again.
As you can imagine losing acceleration without warning is extremely dangerous and I'm concerned the next time it happens I could have a tractor trailer truck plow right over me...! The dealership cannot recreate the incident and doesn't know what the issue is. It seems like a lot of people are experiencing this issue, I don't understand how the dealership cannot know what the cause may be.
PickyP, sea2sea, or anyone else with this problem: did you ever figure out what caused the issue, and how was it resolved?

the situation you are experiencing is called (lymp mode) this condition occurs whenever the is a lost of connection between any of the systems that control engine rpm ( pedal sensor, throttle position sensor, map Sensor, if you have an AWD model, the all wheel drive coupler in the rear of the truck, ) this cars are equipped with a CAN Protocol ( control area network ) all systems in the car communicate with one another in other to provide safety ( ESC and ABS systems) engine management (fuel trim and timing) transmission logic (adaptive learning program) you need to have the dealer do a FREEZE FRAME CHECK on your onboard computer, to me personally I think its your Throttle position sensor that's defective, remember this car has a drive by wire system, hope this helps.
