Santa FE SM (2001-06) :: Transmission Continually Dropping Down A Gear When Keeping Car At About 35mph

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?

Santa Fe (DM - 2013+) :: Transmission Shifts From 4th To 5th Gear At Approximately 60 Km/hr

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.

Santa Fe (DM - 2013+) :: Rough Transmission Shifts Mostly Between 1st And 2nd Gear

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.

Santa Fe (DM - 2013+) :: Range And Fuel Gauge Dropping Dramatically

Just traded in a 2012 Nissan Sentra SR on a 2013 Hyundai Santa Fe Sport and have a question about the gas mileage.

My Sentra always read 28+ MPG, but it was a known issue that the reading was almost exactly 3 MPG off; thus, I was hitting about 25 MPG most of the time. I could typically get by for a week and a half, sometimes two on a single tank (which was about 11 gallons).

I took the Santa Fe home on Thursday night, filled up from the dealer and reading a range of 384 MTE. As of tonight (Saturday), my fuel meter is reading two notches over the halfway mark and the range has dropped to 232 MTE. I haven't driven anywhere near 150 miles since Thursday, FYI.

The MPG on the Santa Fe started t a measly 12 MPG when I left the lot, most likely due to sitting and idling and lots of stop-and-go driving on test drives. I've since managed to get it up to 22.2 MPG (and feel confident it should eventually read about 25 MPG, about the same as my Sentra). Even though the MPG reading is going up, I feel like I'm going to be filling up the tank again without hitting a full week of driving (and this is a bigger tank than the Sentra). I'm not getting the difference. Is there an issue that I'm missing here? After checking in with the dealer that the previous owners used for service to ensure there were no red flags, they did tell me that it had an active bulletin for a software update. I've read in other places here that this update can have some effect on the MPG. Any thought on if these things are connected?

Santa Fe (DM - 2013+) :: Tranny Lagging In Particular When Shifting From 1st To 2nd Gear

I have a 2014 2.0T AWD Limited, now it's about 9000 kms so far with regular maintenance at dealer. Recently I have found the tranny is shifting a bit lagging, in particular shifting from 1st to 2nd gear. I didn't think it was like this when it was new, not sure if it's something wrong, or now I'm getting more used to the shifting and start complaining.

Santa Fe (DM - 2013+) :: Tranny Slipping In 1st Gear At Around 3k RPMs

So dont know whats going on, but after my santa fe sat for a day, I went to go for a drive and when I left the house, the tranny slipped in 1st gear at around 3k rpms. The rpms just shot up, hammered into 2nd, then drove off as normal.

I couldn't get it to repeat it after that.

Facts:
-Car in eco mode
-Car sat for at least 24 hours
-Outside temp 70F
-slippage happened on takeoff at 3k rpm
-No CEL's
-around 11500 miles

What it could be? Should i take it in to hyundai? OR wait and see how it drives the next couple days.

Santa Fe (DM - 2013+) :: Drop Down In Transmission Shifting After Start Up

When the temperature drops below -20 Celsius, I find the transmission shifts weird just after start up. It seems like it goes into second, then third normally, then abruptly drops back into second. I'm pushing very lightly on the gas pedal, so the drop down is weird. A couple times the nav was blank on start up.

Santa Fe (DM - 2013+) :: Hydraulic Transmission Mount Leaking

Looks like transmission mount (driver side/ left) is leaking. I was under the car today, and i found the small dribble of a thick, slow moving, black fluid that didnt have any scent. it leaked down the unibody, onto a brake line(solid line) and even made a few droplets onto the rim and lower control arm.

I traced the leak to the bottom bolt of the transmission mount. i count believe it; but apparently Hyundai engineers opted to use hydraulic mounts versus the more typical solid rubber mounts. it honestly took me 10 minutes, with a flashlight, to check over everything. the ONLY place that the fluid came from was the lowest bolt of the tranny mount. i simply didnt want to believe it to be the tranny mount.

I called a couple dealers, and they all said that if i am the original owner, and i have the 100,000 mile warranty still in effect, its covered.

Lexus GS 2013+ :: Transmission Clunk When Downshifting From 2nd To 1st Gear

Heard a clunk and then have the car feel like something from the inside is trying to stop it when using the paddle shifters in manual mode. Specifically when downshifting from 2 to 1. By the way I did a slight throttle blip, I have done this before with very smooth results but this time it really scared me, I though the transmission broke for a second; when the car did what it did.

Santa Fe (DM - 2013+) :: 2015 2.0T Engine Surging Or Shaking When Stopped In Gear

Not a great definition but have recently noticed an engine surging or shaking feeling when stopped in gear. About 7000KM's and it just started.

Pull up to a stop, foot on brakes and it randomly gives you a sensation the the motor is revving or stalling. You can feel it in both drivers and passenger seat. Haven't been able to see if the changes during this.

Just had it in for service a month ago which shouldn't matter but it seems new since then. Possible flash changed something maybe I don't know.

It's also intermittent so we all know how that works for service/dealership visits. Everything's fine didn't notice it...

Santa Fe (DM - 2013+) :: Hangs In Fourth Gear After Downshifting With Cruise Control On

Got our 2014 back in March and it still hangs in fourth gear after downshifting with the cruise on. Downshifting from 6th to 5th for small hills is fine but on steeper hills when it drops to 4th and hangs in there uncomfortably long.

What I've been doing is switching over to manual and bumping it up to 5th and then 6th. When I don't, it will hang in 4th and rev high and then eventually shift into 5th and 6th one right after the other long after the road has leveled out..

Santa Fe (CM - 2007-12) :: Transmission Stuck At 4th Gear

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?

Santa Fe (CM - 2007-12) :: Transmission Stuck In 3rd Gear

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)

Santa FE SM (2001-06) :: Transmission Stuck In 3rd Gear

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?

Elantra MD (2010-15) :: 2013 GLS Jerky Transmission When Shifts From 3rd To 4th Gear

I just bought a brand new 2013 Elantra! I love the car, but over the past week or so I have started to feel the car's transmission (auto) jerk when it shifts from 3rd to 4th gear. I feel the car hesitate somewhat when going from 3rd and then jerk into 4th gear if that makes any sense. The car has less than 1000 miles and it never did it when I first bought it. The transmission was always smooth until recently. Also, when coasting down the road I feel the car jerk forward when I give it some gas which also feels very strange to me!?

Santa Fe (DM - 2013+) :: Occasionally Slams Into 2nd Gear When Coasting In Parking Lot Or Driving Slowly

Have this problem where Santa Fe when coasting in a parking lot or driving slowly on the road, that their is a bit of a slam into second gear in the auto transmission?

Reason I am asking this is that I have this problem and own a 2013 KIA Sorento, but understand the Santa Fe V6 shares the same motor and tranny. I also read that one long term test of the Santa Fe on the web had this very same problem, but in the end after happening several times, stopped happening.

After reading much info, I ordered a Transmission Temp Sensor as this seemed to work on some cars, but it's really a hit or miss thing.

Santa Fe (DM - 2013+) :: 2.0T Transmission Lurch When Gradually Gaining Speed From A Stop

VERY interested in the 2.0T but when I test drove it this weekend, the transmission seemed to lurch when I was gradually gaining speed from a stop. I wasn't trying to press the accelerator hard. Just driving it like I would my car and gradually gain speed while driving economically. The 2.4 seemed to do this less, but it also did it.

For those who own 2.0Ts, could y'all tell me if this is normal? I plan on test driving other 2.0T in the event the one I drove was an exception, but just curious.
