2005 Santa Fe Accelerator

I have also got myself a 05 Santy 3.5L v6 but even thought I don't find the pedal 'excessively resistant' but the pickup is. Invariably the car needs reving to 2.5-3K rpm before settling down to 2K rpm to take it from stationary to 30-40mph from stop . I have driven 3000 miles but the 'proverbial' break-in hasnt't happened.

anyone can help?

What engine do you have?

I replied to this 2 days ago from another account, but for some reason the post never showed up here. In any event, I have the 3.5L.

Also, after my first tank of gas, and mostly highway driving, I'm getting 16.7 mpg. The much heavier, 10 year-old 4.0L Ford Explorer my Santa Fe replaced was giving me just over 17 mpg with the same driving. Someone please tell me that this is going to improve after break-in.

I have a 2004 3.5L 4WD. Im getting 25mpg. All hwy.

I've got a '05 Santa Fe (funny....I too had a '94 Ford Explorer before!)

oNce the breakin was over, my milage improved to 24 highway...18 city with a

3.5l engine Len

The 3.5 has an electronic throttle. Depressing the accelerator simply activates a sensor under the hood. The computer controls everything from there. It'll probably take a little time to become familiar with its idosyncracies.

As for the fuel economy, I don't know that it will improve. We've had many complaints about fuel economy on the 3.5 Santa Fes. I've never been able to find anything conclusively wrong with any of them. I replaced an oxygen sensor in one of them because the values looked a little funny, but the customer was still getting poor fuel economy.

I also do not know whether fuel economy will improve.

This I do know - that powertrain combo is used in some other Hyundais and Kias. It is a nice, smooth and responsive powertrain, and seems to be able to handle whatever is given it. It also seems to have given VERY few problems in its years of operation (since about '01 or '02).

But one thing this powertrain has never been is very fuel efficient. I've had this powertrain combo in two different vehicles - one was an '02, and now I have an '04. The '04 is decidedly better than the '02, and I love it in my vehicle. But I will never jump for joy over its fuel economy.

But I will gladly keep running it and running it and running it - as long as I keep the timing belt replaced. It is one of the most impressive powertrains I have ever had.

I experienced something a bit different from the way you are describing it with my 2005 3.5L Santa Fe.

The car would either hesitate when the gas was depressed or surge as if I had tromped on it. The dealer reprogrammed the ETCS and this fixed it. I believe these is a TSB out for the problem as well.

Could that be what you are experiencing?

It's more mechanical in nature (and yes, I realize its an electronic accelerator). The problem is that the pedel is very "stiff" (for lack of a better word) when I first begin to apply pressure to it with my foot. Rather than giving way gradually and smoothly, it "breaks" in that it just suddenly gives way. As a result, acceleration is also sudden and jerky from a dead stop. I can overcome it with effort by stiffening my foot and ankle muscles so that the pressure I apply is even and compensates for the sudden give by the pedel.

What was it like before the break-in?

Since I got superior fuel economy from a substantially heavier 10 year-old vehicle (with 154,000+ miles on the all-original hardware) with a larger, more powerful engine I'm forced to conclude that either there IS something wrong with my Santa Fe or its drivetrain is very poorly designed/constructed.

what do you expect from an SUV, didnt you do ANY research BEFORE you bought it??? maybe you be better suited with a horse and buggy... then you wont have to WHINE about your fuel mileage... I own a 2006 Santa Fe.. LOVE it dont care bout the fuel mileage because I knew what it was BEFORE I purchased it...

Pete...

I know that UseNet is the home of ignorant knee-jerk reactions, but the level of stupidity behind them never ceases to amaze me. Yes, I did research before I bought. What I expected was mileage at least approximating the EPA estimates as well as what the company itself touts. I also read many reports from owners (like those above) describing much better mileage than I'm seeing. There is absolutely nothing in any of my posts to suggest otherwise.

So, in short, trying giving those two brain cells that are desperately clinging to a lonely existence on the inside of that otherwise empty skull of yours some exercise before shooting off your ill-informed mouth next time.

Well, I checked some of your other posts in this group and found that this really isn't about anything I said. You're just another belligerant, mouthy jag-off in general:

- "go pay another 20K and get yerself a REAL 4WD then and quit yer bitching... asshole..;-) "

Nah, never had that filling on my 03, cannot remember mpg during break-in, but it was baaaad, after second tank of gas start to improve, now I get

20-22 in the city, 24-26 in the hwy, if I keep the hwy speed under 65 then it goes up to 28, but no fun at all. 03 XL 3.5/5Auto.

not the one WHINIG about my gas mileage. YOU ARE...;-) did your mommy throw you out of the sandbox too early in life?? ;-)

making friends all over I see.. hmmmmmmmmmmmm makes ya wonder dont it???

You might have something sticking then. I'd ask the dealer to look at it again and make sure they understand you have an issue with the pedal sticking when begin to apply pressure. Could be either the cable or the mechanical dealie to which the sensor attaches.
