Hyundai Santa Fe Transmission Problems



  • chucko6chucko6 Posts: 81
    Can't beleive that almost a whole month has gone by and no one else knows anything about a "Rear Coupling" fix for the Transmission issues.
    Sounds like you were happy with it.
    Have the Slams and the Bangs gone for real?
  • This is an update to my July 25 post re tranny problems with my 2010 Santa Fe 6cyl limited. After getting the upgrades mentioned in the last post, I didn't notice the shifting in park upon starting the engine for awhile. Well the software patches didn't fix the problem, it is still doing it periodically. I haven't bothered to call Hyundai customer relations or the dealer, they sound like a broken record and nothing fixes the problem. I have a little over 20K miles. If it gets worse will raise hell with customer relations again. Will keep you posted.

    Can you tell me about this "rear coupling" fix? My dad has had problems with his new Sante Fe from the first week he bought it last May. It hesitates and stalls, and several trips to 3 different dealers have been unsuccessful as they cannot duplicate the problem.

    Any chance we could get the gentleman ( or any else who had their Transmission problems corrected by replacing the "Rear Coupling")
    to respond to the Forum.
    I know there are many of us who would like to know what that is all about
    and if it has been a "permanent" fix ?
    The up-dates aren't working for everyone, so we need some fresh ideas.
  • We have the same problem with our 2001 Santa Fe shifting with a loud bang after remaining in low gear for too long. Took it to Advance Auto for a totally free error code reading...came back with error codes p0720 "Output Shaft Speed Sensor" which in turn created the error p1529 "Trans Control Module" . Hyundai dealer for service and repair closed on Saturday and Sunday so it will be Monday before I can see what the repair costs will be.

    The 2010-2012 transmissions are hopefully different than a decade earlier and of course a lot less use and mileage.
    Don't believe the same problem would have survived that time period.

    Did you ever figure out what this was? I have had this happen twice now to my just purchased "used" car 2010. Last week I thought I ran over something in the road, the car thumped then felt like I put the brake on. After that I noticed reduced power when I was stopped and trying to accelerate. It sat in the parking lot when I went to work and then worked fine on a 10 hour drive round trip over the weekend.
    Went out today and the same thing happened, felt like I ran over something, and the same reduced power. Also noticed when I put the car into park there was a hard transistion to park, reverse and or drive, not smooth and quiet like it use to be
  • No, it hasn't happened again (yet). Only 2x since I bought the car new. It worrisome though. Just hope if anything is going to go out it happens before the 70,000 mile bumper to bumper warranty off. If I don't have a heart attack the next time it happens in rush hour traffic, that is.
  • I have a 2002 Santa Fe. Between 35 and 42 MPH I get a vibration in the front end. Sounds like going over rumble strip. Does not happen below 35 or over 42. Car has to be increasing speed. It will only do when slightly acelerating. It will occur in drive or 4th. gear. It will not happen in 3 gear.

    Other folks on the forum have stated the same problem (*message 354) etc but I cannot find any replies or information as to what the cause might be. It has nothing to do with tires or alignment. Happens consistently at the speeds indicated. Shakes the whole car. Been in shop 3 times and can find nothing wrong? If anyone has any ideas appreciate it. Thanks CoastWatch

    Yes. Transmission. Unfortunately. Make sure you have plenty of transmission fluid. Sometimes it is just the nut on the bottom that gets jarred loose. More than likely, you are looking at have to replace the transmission. So sorry. Mine just sitting in the driveway gathering dust now. I don't trust it to drive it. Have 8,000 miles on rebuilt transmission and he rebuilt with all new parts. It's Hyundai. They need to take care of this problem. Guess not enough people are making noise!
  • While driving on a side street around 25mph, the car lost power as though I had shifted into neutral, and coasted to a stop. Car was towed to the dealer from whom I bought the car and a new transmission is being installed!

    Did you have any symptons/issues with the Tranny prior to the Failure ???

    Let us know if the replacement is New or a Rebuild..
  • I was in neutral sitting at traffic lights and lights changed to green,I had my toe lightly on accelerator and had about 1100 rpm or less. When I selected 1st gear there was a loud metallic clunk and the car went nowhere in any gear. Had to be towed home it was after hours and yet to talk to mechanics. The engine runs fine but it seems the gearbox is now totally disengaged from the engine by some sort of sheared drive shaft, any ideas.

    Maybe it's that "Rear Coupling " I've seen mentioned. Would be nice if someone would tell us what that's all about.
  • Yeah I am not sure, if the rear coupling is the last engagement from the engine to the gearbox or the torque converter I could go with that for sure. Thanks chuck I will try to find a diagram some where, cheers, thommo107
  • Thats interesting. I have a 2006 model & mine just jumped & lost power. Since found out a piece of metal broke off the teeth & I now need a whole new gear box. Would be interested to know if this is a common problem with them
  • Would you please enlighten many of us about the Rear Cupling fix you had done. You are the first to mention it and it might be a valuable post for many of our Tranny problems.
  • I have a 2005 Santa Fe with almost 64k on it and have owned it since 17k, 3 years ago. Recently, I was driving and went to accelerate at a stop sign after going up a steep hill and coasted as my car didn't want to get out of first gear. I ended up parking it for the day and bumming a ride from my hubby. I took it to get looked at today, and they said that the tranny fluid was burnt (which I noticed when I checked it out), and that they don't know how, but I need a minimum rebuild for whatever reason. It's hard for me to believe that I could need a new tranny at 64k, but I guess so. Feedback or ideas would be great. I'm having a hard time thinking about spending that money. Would a flush and new filter do the job?
  • lemon law questions. 1. in which state are you located? 2. were you required to provide any additional documentation and/or did you have additional documentation (I have started a log of my transmission thunks)? 3. did arbitration process use guideline for depreciation? (I live in FL and lemon law here has guideline of 1/120,000th of price for each mile driven. In other words, if the vehicle has 12,000 miles then they would pay 90% of your cost of the vehicle. 24,000 = 80%, and so on.). thanks for the info.
  • mine just went at 35000 miles and it was just after it was in the shop for a recall on the springs ,they said at first it was the coupler or something then next day said it was trasmission also and they give everyone a rebuilt transmission no one gets a new one they are lying if they tell you that I got off the phone with california customer care for hyundai and they told me remanufactured trannys are part of the warranty not new ones so its a bait and switch warranty for 10 years or 100,000 is needed you may replace the tranny 3 times.Also if you are not the original owner warranty is 5year 60000 and if you replace the tranny at 58000 you get 2000 miles warranty on your remanned tranny ..Now how is this company still in business
