Hyundai Santa Fe Transmission Problems

  • If I had just spend near 30 grand for a NEW vehicle and the trans was serviced or replaced several times, I know what I'd do!

    I grab a large piece of cardboard and a stick, write "trans problem Hyundai can't fix" and march on down to a Hyandai dealer that are just today introducing their new line of cars, the Equus.
    I'd find a public sidewalk, stand or walk peacefully and have an informational picket protest. If you have an 'in" at a TV station inform them what you plan to do.

    I think this would work the best on larger Hyundai stores in major metro areas. Just bet the company reps would talk to you now and they couldn't say that haven't heard about the problem.

    Glad I read this forum, first, before I purchased a Hyundai vehicle!

    Agreed, why not alienate the dealer when they've basically dumped the customer? Anyone with lingering trans problems needs to hold their feet to the fire. By the way, why the silence from all the consumer protection agencies?

    It's disappointing to hear about these major problems. Hyundai is on the rise - producing some nice looking and nice performing vehicles. If they don't address these quality issues - they'll be right back down where they started. Their reputation is not that strong for them to ignore these serious issues! i have the '07 Santa Fe awd limited - most of my issues are nusance ones - nothing serious and any that occured during warranty were taken care of... but nothing like what I'm reading about here on the 2010 models! I wouldn't waste my time with that kind of protest tho'... with all the ammunition from this website/forum - I'd be talking to the local news stations to make it as public as possible - then see if it's the dealership or the manufacturer that's blowing smoke! This is unacceptable.

    In my case the Hyundai dealer has always been up front with me on the transmisssion problem. All available updates have been done and transmission replaced once. My SF has been held over night a couple of time and I always had a loaner to drive. It's not the dealers fault, it's the Hyundai engineers. They are grasping at straws. Get rid of the 6 speed and go back to the 5 speed, problem fixed. 2009 and earlier do not have the problem we are all experiencing.

    Just trying to help. Those with Manual Trans benefit the most from accelerator adjustment, as the flat spot makes it tough to drive a stick.

    ecotrklvr,

    Try driving a automatic 6 speed that occasionally has a dead spot with the throttle. My 2010 SF Limited with V6 & 6 speed is currently in the dealers shop and I doubt if they will find anything wrong. Time to look towards Honda for a replacement.

    Make note: this is the 368 thread on the transmission subject. Enough is enough.

    Correction: Note, 2010 Santa Fe Limtied is the same as the 2010. Should read: Note, 2011 Santa Fe Limtied is the same as the 2010.

    Throttle dead spots are not good with either trans.

    With Drive-by-wire throttle sytem like this, the accelerator is now just an electronic proportional transmitter. So now Transmission, Engine/Trans ECM, ECM firmware, and throttle hardware are now suspect. Point is, you may now have two problems.
  • Hello folks,

    My wife and I just bought this vehicle with Navigaton at a good price new from the dealer. I am pretty impressed with the build quality of Hyundai... I didn't expect it. It reminds me of Toyota during their upswing days. We compared this to the Ford Edge and Chevrolet Equinox and truthfully the Hyundai was slightly less refined than the Ford/Chevy in my humble opinion, but still a star and we got a terrific price. We are satisfied and was pleased with unbelievable fuel mileage on highway driving. I was getting 31.8 MPG on highway at 60 MPH and working it for the best possible mileage.

    Anyhow, my question is about coasting with this transmission. To my surprise, this vehicle doesn't freewheel during release of the accelerator. Oddly the engine stays engaged to the wheels and actually it's a drag on the vehicle when releasing the acceleration. I've never had any vehicle work this way.. is it normal or is this a glitch with my SanteFe? If you are at 60 mph and at about 2100 or so RPM's, on any car if you let go of the accelerator the engine will drop to around 1k rpm's letting the vehicle coast. Not my Hyundai. As good as this vehicle gets with mileage it could be better if you didn't have the drag of the engine when letting your foot off the gas. In this regard it acts like a manual transmission and does not disengage the engine from the transmission unless shifting to netural as with a manual box.

    Anyone shed some light on this for me?

    Thanks!

    Are you sure it is AWD? I hope they didn't tell you that and charge accordingly?">link title
    Because I'm pretty sure that 4 cyl models were only FWD. Which do get better FE than the AWD's.

    I am not very familiar with your transmission, other than to suggest ensuring that the OD button is not pressed in (which locks it out). But this would restrict you to one gear lower, higher engine RPM and FE would suffer at highway speeds.

    I've driven a GLS 4-cyl AWD. I did not notice the effect that billaggie describes. There is no Overdrive button, but there is an AWD Lock button. Maybe this is the culprit? Or perhaps the rear Emergency Brake is not releasing? Just my $0.02.
  • Yes, I'm sure it is AWD. The sticker says so.

    It's not the AWD lock button. I tried that and no difference. I can't for the life of me figure out why such a feature would be implemented. Maybe it has something to do with the anti-skid... but disengaging that also has no effect. Placing it into netural is the only way to freewheel --- as one might do approaching an interstate exit or just coasting into a new lower speed zone.

    THanks for the comments but still wondering about it.

    Actually... there isn't any automatic transmission that actually "freewheels". All automatics stay in gear.... You may be used to older automatics that stay in top gear for a longer period of time (as the car decelerates), or even have a higher final drive ratio than the Santa Fe.

    Not discounting that there may be something wrong with the car, but a lower top gear, AWD hardware and an electronic transmission that downshifts or holds a lower gear when coasting downhill, probably all add up to a different driving experience than you are used to...

    My wife's SUV (not a Santa Fe) has a 6-speed automatic, and it will hold at 35 mph all the way down a 1/2-mile long hill near our house... My son's '92 Acura would be doing 60 by the time you got to the bottom, if you didn't use the brakes. By the way, I hate her transmission...lol.

  • I don't claim at all to be a mechanic. But what you are saying does surprise me. Not that I don't believe it... maybe just I don't understand it. Every car I have driven will drop in RPM's (substantially) when the foot is removed from the accelerator. As best my memory serves me, they drop substantially. This SantaFe is truly the first vehicle that the RPM's stay the same on the engine when the petal is released. At 65 I recall the TACH running around 2300 RPMS. Letting go I would expect some drop, but there is none. It stays right at the same RPM's. So I guess I don't understand any of this really. I just know that there is a noticeable drag on the car when coasting. And it's the only vehicle I have ever felt it down shift when coasting up to a stoplight or sign...

    So this is normal? Thanks for your reply.

    I guess the difference then is Cda to the USA. Cda didn't get AWD 4 cyl in 2010. Is there a Sport mode? Click it off. Sounds like it might be the nature of the beast tho since another one does similar. I have found (the few times I have driven a new auto) that since DBW has been incorporated, there seems to be less freewheel type feel on deceleration. I suspect that ironically enough, they are doing this on purpose and it is probably shutting of fuel to the fuel injectors. There are numerous sensors that allow the tranny and torque convertor etc etc all measure vehicle speed, rpm, gear, throttle position, throttle pedal position etc etc. So while in the old days, the freewheel feel, was still 'idling up' the engine, which they must have been able to do enough comparisons that the new style uses less fuel. That's my hunch even though it does seem non-conducive to using less fuel. Maybe the torque convertor is hanging more/longer than it should during the message to turn of fuel injectors?
  • I had the same Dead Spot issue on my 2011 Santa Fe Limited V6.
    Here's the FIX. Since Toyota had the runaway accelerator problems, Hyundai built in a circuit on the brake light switch that will defeat the accelerator,(since it a cabless system), same as cancelling cruise control. If the brakelight switch has not been adjusted properly, any slight, and I mean slight motion on the brake pedal, will cause the accelerator pedal to become inoperative. Try driving and accelerating, and while doing that, press the brake pedal slightly. The car will stop accelerating. You'll figure it out. My dealer took 4 visits along with my ranting, they finally discovered the problem. All it takes is an adjustment to your brakelight switch.
  • I'll try your idea and see if it works for me. Do you know if your Hyundai dealer has instructions from Hyundai on brake light switch adjustment? My 2010 SF Limited was in the dealers shop for 3 days and after 85 miles of all kinds of different driving could not duplicate a throttle dead spot. Maybe your findings will solve the problem I have. I did notice that my mileage has dropped about 3 - 4 MPG and I'm wondering if my dealer made some kind of adjustmeent.

    Thanks for your input.
  • bookinu2,

    Tried your suggestion with the brake and you are correct. The slightest pressure on the brake pedal will prevent the car from accelerating. So my next step is to show the dealer and see if he knows how to properly adjust the brakelight switch. I'm thinking that a red light forward of the dash coming on when pressing on the brake will help keep me off the brake pedal. Wonder what the effect is by adjusting the brakelight switch?
  • My dealer said the he went to the Hyundai Tech Line and found out about it from another dealership. It's a network thatthey have similar to what we are doing in this discussion. Now that I'm aware of it, I don't have any issues about it. Just don't be a 2 footer.
  • Hyundai needs to wake up their engineers. I bought my 2010 Sante Fe new. My transmission has 11,000 miles. It is slipping just like the others I am reading about. It started a while back. I asked a friend of mine if his 2009 was slipping and he said it was slipping too.
    Hyundai, you got a problem and we all know it...please take care of it now. It's a nice car but, the transmission has got to be fixed. Thanks.
