Santa FE SM (2001-06) :: Transmission Continually Dropping Down A Gear When Keeping Car At About 35mph
Dec 30, 2011
My car is a 2004 Hyundai Santa Fe 6 cylinder all wheel drive. Had an issue with the transmission continually dropping down a gear when keeping the car at about 35mph... no codes were showing nor any lights on the dash were on indicating a problem... dealer said the catalytic converter was the problem. changed it and it did not fix the problem...brought the car back to them and they said it now is showing a code and the service engine light is now on... the code showed that the Crank Sensor and the Throttle Position Sensor were bad... I asked why they had to change the cat and they explained
That they had to change the catalytic converter to get the correct "back pressure" so the computer would then recognize the actual problem and would direct them to the real issue... They assured me the cat was bad...in other words they had to change the cat out or they would not have found the problem... I think i got scammed and they really didn't know what they were doing and it cost me a bunch of money... is there any connection with the cat and those two sensors that could cause this scenario?

I travel on the highway frequently and when I am cruising at 115-120 km/h my gear consistently drops from 6th gear to 5th gear then back to 6th gear. I am not pressing hard on the gas just keeping it at a normal pressure. This is the 2016 Hyundai Santa Fe brand new only 6500km. I brought it to the dealership twice already and they found nothing wrong. Saying there are no error codes when scanned and when they drive it nothing happens.
On my second visit I showed them a video of what is happening. It was two minutes long and within the two minutes my gear down shifted 3 times. So you can imagine when I am long driving how many times this happens. In order to get around it I have to shift to tiptronic and leave it on 6 gear so I don't get this down shifting incident.

I have an 01 and 02 santa f. I took the v6 out of 01-and put in the 02.put new gaskets on engine new timing belt etc. Got engine in and runs like a champ. But the tranny which looks new I assume its been replaced. It starts out in 2 or 3 all the time want shift into od. Reverse works. So I found one plug dangling I couldn't figure out where it went then i found it. It plugged up on top of tranny. Well now it starts out in first and shifts through all the gears. Drove it down the rd shifted fine. Turned around and put in reverse then when i went to drive it jerked real hard. Shifted out fine so I went to floor it to make it kick down and it jerked again. This time it was hung in 3 or drive cause when I pulled into my driveway it was in high gear and u can put it in manual mode and the light only goes to second and d when it acts up like this. So i killed the car started back up and know it will go into first in manual mode and shift out and do fine?

I have a 2003 Santa Fe 3.5l FWD 155k miles. Car has been incredibly trouble free until now. When the transmission up-shifts from 2nd to 3rd there is a hard jolt. All other up-shift and down-shift points work smooth. Occasionally will shift smooth just after I start the car or if I am accelerating hard. The rough shift happens whether I am in D or use the "manual" shift control. This coincidentally(?) started just about the time I had a battery die hard and an O2 sensor fail. Both have been replaced. Changed the AT fluid and no difference. No engine codes, but I think the AT codes don't show there? What might be going on? Any chance the battery failure had anything to do with this? Seems odd that battery, O2 sensor and transmission all start acting up at the same time.

So I just bought this 03 Santa FE a week or so ago and the Speedo like to drop at random intervals. I'll be cruising along at 60 down the highway and then BAM! nothing happens to the car as long as I don't have the cruise control on...if I do then it sputters and I just take over. Is this more than just a Speed sensor issue?

A few years ago my auto transmission in my 3.5 L engine hyundai santa fe started shifting rough from 2nd to 3rd gear, i did a trans flush and changed the input output sensors, anyway last week it started again, so i just changed the input output sensors again, it did not fix the prob this time, do you think a flush would work.

I took my 2001 Toyota Celica GT in to have the engine re-built due to a connecting rod that was ready to blow. I have taken it back to them four times. First time not dropping into 4th gear car is automatic stays stuck at 3RPMs. Said it was a transmission problem. I said didn't have one when I came in and not having one on my way out.
Nothing wrong with transmission. Said they fixed whatever they came up with and still car not dropping into 4th gear and my hood shakes so bad I have to put it in neutral to stop the shaking/vibrating at every stop sign and red light. Said they changed out the non-detergent oil for thirty weight and the shaking stopped for a minute.
I told them the third time I brought it back that the hood was still shaking, still not dropping into 4th gear. I checked my oil and fluids a day later and found no oil in my car and the tip of my dip stick was black. No coolant in the car either. I told them that this car needs special spark plugs or it will run like it needs a tuneup with no power. I was pissed.
They said that I had two broken motor mounts and the engine wasn't sitting correctly and that is what was causing the the shake and the 4th gear from dropping down. I was astounded..... They replaced the motor mounts and the spark plugs. When I drove it home it drove great. I even took it out to the river to make sure it was running great because I am selling this car and they knew I was selling it.
My buyer took it to Toyota of Orange and had a test done on the car to the tune of $120.00. It came back with upper and lower power steering hoses leaking and that I needed a new power steering pump. And wait for it.... a new head gasket!!!!
Which tells me they never rebuilt my engine, they just fixed the connecting rod. I took the report into them from Toyota and told them that I want everything fixed on this report and I want my car back in three days or I will take you to court.
I talked to the owner today to ask him when my car would be ready and he said by tonight that he had replaced the head gasket. Which still doesn't tell me if they rebuilt the whole engine. I told him I wanted the power steering pump and hoses fixed as well or I would report them to the Bureau of Automotive Repair. With the engine vibrating and jumping all over the place couldn't that have caused the power steering pump and hoses to be damaged? And am I within my rights to make them fix these at no charge as well?

My 2006 Elantra (54,000 miles) shifts really, really hard when it's not cold and passes through the 35 mph range -- hard enough to make you glad you've got your seatbelt on. I've taken it to my regular mechanic and now it's in an automatic transmission shop.
My mechanic changed the fluid (twice), and took it through a "learning sequence". The fluid didn't look that bad and he reported that there were no codes to work with. He thinks I'm going to have to get a new transmission.
The AT shop has confirmed that there are no codes to work with and that the problem begins at 143 degrees. They tell me that the transmission is shifting into a higher gear without releasing the lower gear. They tried replacing a couple of solenoids, but that yielded no change in behavior. Now, they're telling me they "think" I need a new computer. I'm just afraid the trial & error approach is going to cost me a boat-load.

On my 2005 Elantra - my radio, dash board clock, dome light, and keyless entry stopped working all at the same time.
Fuse #25 that controls these features is burnt out. As i replace this fuse, it immediately sparks and blows the new fuse.

My 2010 Santa Fe's transmission has been smooth since the TCM update except there's always a clicking sound when the speed first reaches 30 km/h. The sound only happens once during each trip. It seems like it only happens when the fluid is cold. Once it's warmed up, it's fine.
Yesterday all of sudden I feel something is dragging my car. I noticed RPM is over 2000 when the speed is only about 60 km/h. (not mile). And the ECHO light is not ON. So I shift to '+/-' mode and the display shows 4. I guess it means it's in 4th gear. I shift up to 5th gear and RPM drops right away. ECHO light comes back ON. So is this a symptom of 2010 Santa Fe transmission?
I also feel my brake pedal is very stiff when this happens. And the brake pedal has not much travel distance. If the brakes are dragging car down, can this cause the transmission stuck at low gear?

Finding a solution to my problem with Santa Fe, the gear gets stuck up on the 3rd gear. I have changed all the solenoid and it is still the same.

My transmission got stuck in 3rd gear on the way home recently. I tried disconnecting and re-connecting the battery and that didn't work. Looks like there's fluid around the casing, but I wasn't sure if that was already there or not. What it could be? '07 Santa Fe (3.3L)

There is only one thing I don't like about our new SF. The transmission shifts from 4th to 5th gear at approximately 60 km/hr (36 mph +/-) and the rpm's drop to 1500 rpm. Now, when I want to speed up a tad (which is a frequent occurrence when driving around town), there is a pronounced hesitation before it drops back into 4th gear and accelerates.
In 5th gear at 1500 revs, I find that the engine is 'lugging' a bit. Yesterday, I started to compensate for this by changing to manual shifting as soon as the trannie shifted into 4th gear and leaving it there when I was traveling in that 60 kph speed area. For me, this is MUCH better and I quite like doing some of the shifting any way since I spent so many years driving manual transmission equipped cars.
How have others found the car to be when driving around town? Other than that, I really enjoy this car. Easily the most comfortable seats of any car I've ever owned --- their design provides terrific lumbar support and the new cloth material has a great 'feel' to it.

Just experienced something new in my less than a week old 2.0T. This morning was the coldest day since buying it (-15c). I had the block heater plugged in and it started up well. Let the engine run for my usual 30-40 seconds before putting it into gear. Reversed well, but was a bit slow shifting after putting it into 1st.
For the first 5 minutes or so of the drive, the shift were pretty rough. Mostly the shift between 1st and 2nd gear. Things got better after that and were fine for the rest of my trip and also an hour later when I came home.
Is this just a case of a very cold transmission and fluid, or is it something else? I've never owned a car that had such rough shifting in cold weather. Sluggish shifts yes, but not violent like these were.

We have a 2010 Santa Fe AWD LTD with about 140, 000km on it. It recently came back from front suspension work. The suspension is fine now, but we notice harder shifts in the transmission. Also, there seems to be a vibration just before shifting gears and when under load (like going up hill) seems to slip (like on ice) about once every second until the shift is made. Once the shift is made it drive smoothly until put under pressure again. Even stepping down a bit on the accelerator will cause this slipping feeling (or maybe its loss of power). Just had new plugs put in and a tuneup so it's not that. Could something from the suspension work cause these symptoms?

My 2010 Santa Fe has some transmission issues.
Now and then I notice the vehicle is kind of slow and every now and then when going from P to R, or R to D, it enters with a bang and after that the Gear indication in the dashboard disappears. At that moment the car is completely sluggish, like if it is some kind of lock mode. I have to turn it off and on again and all is back to normal, however, after an episode that it enters with a bang the transmission doesn't react as well as normally, it takes a while for the car to behave normal again.
The fact that the gear indicator disappears from the screen on the dashboard suggests to me that this is a computer problem more than a mechanical issue.

Its not my car but my sister in laws. She stopped by our house tonight to pick up her kids and when she put the car in drive it showed both drive and 2nd gear. we tried disconnecting the battery so she could at least get it home (3 min away) but it didn't change anything.
She left with it still in 2nd thinking she could make the short drive without any problems but half way home it shifted down to first and it wasn't even driveable. Everything i have read on the web (which was not really specific to the santa fe) was say that its stuck in safe mode. What could have cause the problem? So far no check engine light has come on.

ok, I had quite bit of work done, prob over yr ago All oem parts, timing belt, crank sensor, idler pulley, some other things while in that area. So when he was done I got this vibration when it goes into gear never in park only in rev. or drive but only in cold weather and after it warmed up it was go away. No Trans service was done. He kept it overnight outside, had the timing cover off rolled it in the garage, started it and seen that the belt was flapping crazy. So he thought it was that. well every cold morning I have to wait till it is warm to not hear that sound. it only happens during cold mornings never in summer. He had back in his shop 3 times after parts were installed. and its to this day isn't the same. its unfortunate that I didn't have many cold mornings when he had worked on it. but after I had it and the next cold morning it was there.

Seems lately when driving up a long incline the Trans seems to slip back to third gear from overdrive. I watched the tach and it jumps up like it's went to another gear. But goes right back into overdrive. It will keep doing this as long as we're under load, like going up an incline. If I put it manually into 3rd and keep it there it won't do it.
We went on a long trip last summer and it kept doing it and it threw a tourque converter code. I can't remember which one tho. I did a drain and fill and it made it better but it's doing it again. We have 167,500 miles on it. I was told by Hyundai that it would be around $2800 for a rebuilt tranny. If I was to need one. Don't think the TPS would cause the shudder right? Seeing it doesn't do it when I keep it out of overdrive.

I have a 2010 Passat 2.0T with 42k miles. Since it rolled over 38k on the odometer, I have been having a problem with the tranny dropping down to 5th, sometimes even 4th, while at cruising speeds (80-85 mph...Live in Texas). I notice this mostly on long drives (Ft Worth to San Antonio). The problem usually occurs while in Drive when I punch it to pass. Although, this is not always the case; sometimes it will drop down by simply letting off the accelerator or pushing the brake.
When this happens, I have to manually shift it back into 6th and its a crap shoot if it stays there when I put it back into Drive. This last trip I drove 90% manually because it would not stay in 6th in Drive. After calling the dealer and them telling me that it was probably a cruise problem, I turned off the cruise and drove without it with the same results. I bought this car used with 19k miles; Is the transmission covered under warranty or are there any recalls on this?
