Automatic Transmission problems of the 2010 Hyundai Santa Fe

I just purchased a 2010 Hyundai Santa Fe today and it seems like the transmission is shifting hard between gears.

Transmission slams into gear, also slips into gear and sometimes moves when in park.

Started car to back up out of driveway. Car jumped a little. Continued on road and felt little jumping at random. Went slow and tried to brake and accelorate to understand trigger. Turned around after 1. 5 mile to head back home. A few yards in the car made loud dropping sound and grinding and scraping and would not accelarate. So loud I thought the bottom came out. People pushed it into parking lot for me. Aaa towed it to dealer. 24 hours later told it was a transmission problem. 24 hours after that told they are replacing with new transmission. Asked if this would trigger any future problems and they claim no.

The vehicle stops or stalls on shifting from first to second gear. It has just died merging into traffic from a stop sign and I have been forced to roll to the shoulder. It will not always pull up an incline from a stop such as a steeper driveway. I have been sucesful to "fix' this by shifting into neutral and then back in gear. This problem is well documented in the Hyundai forums on line.

I have a 2010 Hyundai Santa Fe. Sometimes when it shifts from 1st to 2nd it feels like another vehicle has rear-ended me. It happens a lot when the Santa Fe is cold, but it has happened at other times also. It will also hesitate as it goes from one gear to the next. I have had it to the dealer twice (once I left it over night so they would have it when it was cold) and of course it didn't do it for them. When the transmission hesitates the tachometer will go between 3000 and 4000 rpm, and then lurch violently as it becomes "unstuck. " every time I go to the dealership for an oil change or any other work, I mention the transmission problem. The last time I was there the technician said they contacted Hyundai and was told that is normal. That is not normal. I received a questionnaire from Hyundai about my Santa Fe and again mentioned the transmission problem. I never heard from them. I have read other owners have had the same problem and Hyundai will not acknowledge that there is a problem.

I have a 2010 Hyundai santafe with 6900 miles. Three times in the last week the vehicle would not shift and then it would slam into gear making a banging sound and would surge forward. It was like being hit from behind. Each incident occurred at speeds of 20-25mph while accelerating. I am very concerned about my safety when driving this vehicle.

I bought a pre-owned 2010 Hyundai Santa Fe on 12/13/10 with ~14k miles I was driving to phoenix today 12/25/10 and when leaving a stop light there was a clunk and then my transmission went out. After doing research today I have found that 2010 Santa Fe's have issue with their transmission but no recalls have been issued. Me and my 13 year old daughter are now stranded in phoenix until we can get it repaired. Please push for a recall so this stops happening to people and Hyundai corrects this problem once and for all.

On my 2010 Hyundai Santa Fe, the transmission intermittently slips, then slams into gear with such force that the vehicle lurches forward, and feels like you are being rear-ended. There are numerous other reports of this happening, however Hyundai has not issued a recall for same, and the dealer has been unable to fix the issue.

The contact owns a 2010 Hyundai Santa Fe. While driving approximately 25 mph the contact took her foot off of the accelerator pedal and was coasting. When the contact applied pressure to the accelerator pedal the rpms increased and there was a hard bump and a shutter felt inside the vehicle. The failure occurred intermittently. The vehicle was taken to the dealer three times. The transmission adapter was reset, the keep alive memory and adaptive values were cleared, and an ecu update was performed. The failure continued to occur. The contact was taking the vehicle to the dealer a forth time for diagnostic testing. The vehicle was not repaired. The approximate failure mileage was 7,889. Updated 5/9/11.

Bought our 2010 Santa Fe with 2700 miles (the owners wife had been driving it) on November 11th. Almost immediately I noticed that it banged loudly and lurched somewhat upon going from reverse to drive. It does it at any time of day so it's not limited to cold starts. Brought into dealership where they tested and reset the computer. My service manager seemed to be aware of the obvious problems the transmission is having. Then was told it was my transmission and they ordered a replacement. I asked if it would be new or rebuilt, they said new. Then I was told it was policy to put in rebuilt. It only has 5000 miles on it! after some conversation, they agreed to put a new transmission in it. They still have my vehicle-over a week now and I might not get it back for another week. Still don't have the part. . . . . So we'll see when we get it back.

Problems with my 2010 Hyundai Santa Fe with 11,000 miles. Like hundreds of others my car bangs when starting and bangs so bad while trying to shift gears when cold that I thought I was hit from behind. When driving slow the transmission shifts so hard that my wife is afraid to drive this new veh. After reading about all the problems others are having on edmonds. Com I thought I would e-mail you people. The way, reps at the dealership I bought say that this is normal, I have to laugh.

Oct 2010 first incident- with a cold engine in the morning while traveling between 20-40 mph my 2010 6 cyl Hyundai Santa Fe lurched forward with a loud bang as if we were hit from behind. We had 6230 miles on vehicle. Over the next 2 days the same thing happened several times not as severe as the first incident. After checking the internet found many reports of similar incidents. Brought to dealer who denied hearing of this problem, kept overnight, couldn't duplicate problem and reset adaptive learning and reset driving history. Problem started again March 2011 on March 8, 2011 brought to dealer kept overnight, couldn't duplicate problem found transmission fluid low, reset transmission, did an update they said was related to a computer module that was related to the problem. Vehicle had 10,000 miles. Called Hyundai consumer affairs and had a case opened to document problem as I may have to go through new york lemon law if they don't fix problem. March 15, 2011 tramsmission problem back again called Hyundai consumer affairs and had them reopen case and another appointment scheduled with dealer on March 23, 2011 to test drive with tech and service manager. This will be third attempt to fix transmission problem.

2010 Hyundai Santa Fe. Transmission problems. "lurches" from 2nd gear to 3rd gear. Loud clanking sound when starting (not on all starts, about every 7-10 starts). Slow speed sputters. Slips at slow speeds when accelerating then slams into gear very roughly.

Safety: 2010 Hyundai Santa Fe engine seems to race at slow speeds/coasting, then automatic transmission "skips" then "slams" back into gear. Brought back into dealership twice, first was told they had heard of a similar issue but that it was "within tolerance" so it was not fixed, when it happened again and before starting a long trip I took it back and had their senior tech drive it home (to see if cold starting could be a contributor) they "reprogrammed" the transmission and told us it would be in "learning mode" for the next few thousand miles. Problem has happened twice more in heavy traffic. Want to take it back for repair but need some help in telling them what (and obviously from the online forums) how widespread this issue is.

I have a 2010 Hyundai Santa Fe. I have been having problems with it shifting. It will shift really hard and sometimes when I go to give it the gas it will rev to 4rpms before it goes then it bangs in to gear. I have it back to the dealership a few times and they tell me they can not replicate the problem. This is being to be really frustrating. I have had much patience with the dealership, but when the say they put it onto the computer and can not get a code and there is nothing wrong with the vehicle. I am getting afraid to drive the car. I don't know what more to do. Is there anyone out there that has the same problem and has had it fixed so I can tell the dealership?.

With a cold engine in the morning, my 2010 Hyundai sante fe vehicle transmission shifts with a loud "bang" around 10mph. This is sporadic. Also at start up, the vehicle while sitting in park, does the same thing when started, though not as forceful at when driving. I now have 4800 miles, and this has been happening every 2 or 3 weeks minimum. I used to think little of it until it has begun repeating even after the dealer "reset" the software. I also notice now there are several auto websites very aware of the problem. . Read more...

My 2010 Santa Fe on occasion will lurch forward when started, and makes a thud sound from the transmission when this happens. This started when the car had about 1500 miles on it. Then at about 5000 miles, when starting out it shifts from 1st to 2nd very hard, enough to nearly get a whiplash and feels like I have been hit from behind. I told the mechanic at the dealer and he said he would do the recall which had been ordered for another problem, and maybe that would help. It did not help. It has happened several times since then.

2010 Hyundai sante fe awd transmission issue. Immediately upon starting, while car is in park, car idles high, wants to lurch backward, but is "caught" by the fact that it is still in park. Makes a loud bang sound when this happens - almost like something in the frame or elsewhere in car catches it. Then, when putting in gear, it idles high and accelerates very quickly without foot on gas. Need to keep foot securely on brake for safety. Hyundai denies a problem when it is brought in for service. Other Hyundai Santa Fe drivers indicate problem is with transmission and gets worse over time, including having stalls while in traffic,, unexpected acceleration, car won't shift in 2nd and 3rd gears. Please get Hyundai to address this problem and issue a recall.

Brand new 2010 Hyundai Santa Fe limited 6 speed auto transmission. Vehicle sometimes makes a loud bang from transmission at start up. Vehicle lurches forward when started up in park. Also loud band when engaging reverse. Has a problem shifting sometimes from 2nd to 3rd gear,a slight hesitation sometimes. Car has also died on me for no reason when pulling out of a junction. Will be taken the vehicle to my local Hyundai dealer ASAP. Love the vehicle but seriously worried with the transmission issues. Most of the issues are happening daily apart from the stalling issue which has only occurred once.

Brand new 2010 Hyundai Santa Fe intermittently lurches forward and reverse when started up in park. Appears as if starting up "in gear" when in park.

2010 Santa Fe. I get a loud knock (which jerks the vehicle) every so often when I start the vehicle. The dealer cannot find anything with it. I also get a pause at times going from 2nd to 3rd gear in my automatic transmission. Dealer refilled transmission fluid which seems to have helped that a little, but it still jerks at times while shifting gears. The knock has not stopped however. Just happened again yesterday which is at least the 15th time it has happened since we bought it in March. I have talked with others who have a 2010 Santa Fe and they say they have experienced the same problem. All of it seems to be a transmission issue to me, but the dealer says they cannot find anything. Not normal, and definitely should not happen with a new vehicle. I really like the vehicle outside of that.

I have a 2010 Hyundai Santa Fe awd. We bought the car with 8 miles. After one week we started to notice a banging sound when the car would shift at low speeds, sometimes it was so severe the car would jerk forward violently. We have taken it to the local dealer twice and they tell us there is nothing wrong. Today my wife was coming home from work and slowed down to let some kids cross the street, as she was slowing the car banged and jerked forward so violently she thought she was going to lose control and hit one of the kids! I was just looking online for other complaints and there are a lot, complaining about the same problem. Something needs to be done about this, or someone is going to be killed!!! by the way, thanks for the Honda odyssey brake recall, I sent in a complaint about that, you folks are great! thanks for your time.

The contact owns a 2010 Hyundai Santa Fe. While driving 25 mph, the transmission would throw itself into gear with a hard bang as if it were hit from the rear. The vehicle was taken to an authorized dealer who reset the computer; the banging stopped for a while. The failure occurred again but the dealer could not duplicate the failure. The manufacturer had not been notified. The failure mileage was approximately 3,000 and the current mileage is approximately 10,000. Updated 01/18/11 updated 01/31/11.

We purchased 2010 Hyundai Santa Fe almost from the start we notice an occasion she would bang into gear while driving in 30 - 40 mph traffic and stops. After numerous trips to dealer their answer was they couldn't duplicate. The last 2 trips to the dealer I explained if you drive in stop & go traffic moving about 30-40 mph you will feel the bang like you have been rear ended. I was told the cannot test for that period of time they reflash the computer. Then listed it as unable to duplicate and set up n appointment with a factory rep. For December 15,2010 @10:30am. My wife will not currently take her parents for treatments at the medical center because the bang startles here parents and she fears a breakdown. Unacceptable for a car less than one year old.

On a large number of occasions, the transmission of my 2010 Hyundai santafe awd would slip into neutral as it went through the gears. That is when the car was still relatively cool as in the morning, it would start off in first, shift to second and then on some occasions slip into neutral. With a little on and off on the accelerator it would then go into third and then shift normally. The only times that it would happen was when the transmission oil was still cold. Hyundai changed the transmission computer per a service bulletin. When the condition reappeared it then offered to replace the transmission in its entirety. This seems to have solved the problem. My concern would be that if it did happen when one entered a line of traffic. This certainly could have created a dangerous situation. Till the situation was resolved, it happened on a significant number of occasions. Hyundai was responsive to the problem, and seems to have tried to address the problem. The vehicle has approximately 10,000 miles at this time. It was purchased new in April and the problem began in June. That at least is when we first observed it.

My problem is with a 2010 Hyundai Santa Fe, 4 cyl. The problem is that the vehicle sometimes hesitates to move forward, and then suddenly accelerates. It happens when the vehicle is stopped as in traffic. When the accelerator is depressed the vehicle does not immediately move forward, and then it suddenly moves forward very quickly. I have reported this problem three times to my dealer. They had a " factory" service mgr ride with me for about a half hour. The problem did not happen. It has happened unexpectedly many times since then. I was almost in a serious accident from this problem. The dealer put the car on the diagnostic machine and finds no problem. Today a friend of mine who has a gas station in asheville, nc had a customer ask him about the exact same problem with the identical vehicle. I spoke with the individual and his problem is exactly the same as mine ! that is why I am writing to your office. I have filed a complaint with Hyundai [xxx] but the problem continues. I will be happy to let the gov test my vehicle. It is a safety hazard. My daughter had the same experience and said she would not drive it any more.

2010 Hyundai sante fe transmissions bangs into gear between 1-2 giving a feeling as if someone has rear ended your car . It also has a rocking motion while driving. Mostly does this first thing in the morning but will also do it randomly. Call Hyundai and they claim that they do not have any knowledge of a trend on transmission problem with the sante fe. I took car to dealership for them to look at and left it overnight they could not find any problem. At my suggestion they reflashed the computer and it helped for a week and now the car does the same thing banging/learching into 2 gear.

On Tuesday, June 8, 2010 I was on a busy interstate highway with fast moving traffic and my car lost all power while traveling at 70 mph. Fortunately, I was able to barely glide the sante fe to the shoulder and stop without incident. Follow up: 3 pm visited Hyundai service center and was told that it was not a throttle problem. They are in contact with CA service to determine cause of problem. Friday, 6-11-10 after complete testing of all circuits, Hyundai declares no source of problem. Auto was picked up at 4:30 pm Hyundai assistant service manager: bob wood Hyundai case # 3982284 the specifics are: ? SUV was purchased 8/09 and currently has 5200 miles. ? cruise control was on but not engaged. ? gas tank indicator on one-half. ? with my foot on gas pedal the initial instinct was that the engine had lost all power. O pressing harder on gas pedal had no reaction. O there was an opening in traffic and with the SUV forward inertia I was able to just reach the road shoulder. O observed that red indicators were on (battery, oil) ? reset transmission selector to park, turned off key. O first restart-nothing happened o second restart SUV started and I did not turn off until reaching home. Obviously, this is a serious life threatening situation that needs to be researched thoroughly and corrected.

2010 Hyundai Santa Fe v6 awd limited I put the key in the ignition to start it, and the vehicle lunged forward approximately 6 inches. The vehicle was in park when I started it. Luckily my foot was near the brake, so I instinctively slammed on the brake. I do not know how far it would have gone if I had not depressed the brake pedal. Luckily the vehicle in front of me was far enough away, also lucky that there was nobody walking between my vehicle. I looked on a hyundi forum and there several complaint's the dealer said they could not find anything wrong I asked them to contact the factory and they did not have any complaint's onthe same problem . I told them to look at your web site and the forum . I am a auto mechanic and I can tell you if the park paw that's holds the car in place lets go after constantly getting pulled away when this happens the truck can take off and hurt/kill somebody please help!!!!! thank you.

Luckily the vehicle in front of me was far enough away, also lucky that there was nobody walking between my vehicle and the one in front of mine. I took it to sport Hyundai Dodge, they were very nice. They put it on their computer scanner, and of course it did not come up with any problem codes. Luckily I do not have remote start on this vehicle, because who knows where the vehicle might end up. I was also lucky that I was actually seated in the vehicle and not leaning in to start it. Hopefully this was a fluke situation and will never happen again. However, I will have to remember to start this vehicle with the brake depressed if there is something in front of my vehicle. Toyota depended on their computers too, which never came up with any error codes either, and they thought the customer was at fault, and look where it got them!.
