Lank;5889243 I suspect that the just torque converter was killed said:No DTC codes for either transmission or engine ? Cats usually don't plug unless you had previous engine woes - like a bunch of misfires. When plugged unusual not to see a DTC, same with high temp in the tranny, should trigger a DTC .
Sometimes best to get 2nd opinion when faced with major expense, but at least if your Theta II seizes you get a new engine for free !
Yes, I also have a 2014 Santa Fe HyundaiI have a 2014 Hyundai Santa Fe Sport, AWD. For the most part, my wife and I really like it. We had the engine replaced in 2017 because it started dying on us. Come to find out, there was a recall due to the engine's internals grinding themselves to death. So, for the most part, the car has been pretty good.
However...we've been having some serious issues with the transmission. For instance, after the car sits for a few hours and we decide to drive it, there's a horrible slipping feeling in the transmission from 1st to 2nd gears. The engine will also rev very high...sometimes close to red line. It'll do this for about a second, then after that, the transmission shifts fine. The next problem with the transmission is while coasting down any kind of incline. There's an abrupt jerk when the transmission downshifts from either 3rd to 2nd and/or 2nd to 1st. We took it to the dealership numerous times. After all of the diagnostics and testing, they found absolutely nothing wrong. I was shocked. They reprogrammed and serviced the transmission a couple times and nothing changed. They even had our car for 2 weeks at one point and of course they could not reproduce the issue. It also never threw a code or caused the Check Engine Light to come on! I recorded it on my phone happening to us about 20 times. I even showed them other videos of the transmission doing its thing. It didn't matter one bit. If they could not reproduce the issue, to them, it didn't happen. I wrote to the dealership begging them to send someone over our house for a couple mornings so they could see what I/we were experiencing. Guess what, no response. Can you believe it's still happening to this very day? Of course we're over the 100,000 mile warranty. Our only saving grace is the dealership told us that if the transmission fails, Hyundai will most likely fix it under the warranty because we've been complaining about it for so long. I'll believe it when I see it.
Does anyone else have the same issues that we're having...or had the same issues? Does anyone know what might be causing the transmission to slip like that almost everyday? What would cause the abrupt downshift while coasting down an incline? This has been nothing but a huge headache. I just want to know what's causing those things to happen!!!
Thanks for reading my rant. Hopefully it made sense.
My 2014 did that and Hyundai replaced them engine but now something is going on with the transmission 😐 it’s at the dealership now and haven’t heard anything so far today😞 frustration is setting inSounds very much like my 2017 SFS!! Mine had the same hard downshift, especially when going from 6-5 gear. It was a very hard jerk. We had the tranny replaced last October (car was only 10 months old!!), and things were going ok for a couple of months, but now it's back and worse than ever.
I brought the car to my local dealer back in May and they kept if for a few days to try and figure things out, and they did a transmission "reset", however, nothing has changed for the better, actually a little worse. There was a couple of times in the last two weeks where it downshifted two gears from 6-5-4 very abruptly in about a 1.5-2 second span while starting to climb an incline of about 10-15 degrees while at highway speeds around 110 km/h.
Something else that has happened since the "reset" is the reduction of speed while starting starting to climb a shallow (less than 10deg) incline while at highway speeds while also pressing harder on the accelerator pedal. I've seen reductions in speed from around 5-8 km/h when this happens, but i have been increasing pressure on the accelerator. It's like the car isn't responding to the increase on the pedal but instead slowing down. Eventually, the car grabs and then does the hard downshift in gears and then speeds up.
Not sure what to do anymore. We've had the car for about a year and a half and I don't have the time or patience to keep bringing it back to the dealer.
Sounds like a fluid temp sensor but dealer decided to do whole unit replacement.I have a 2013 SFS, 20T with 49000 miles. At 47500 the tranny started hard shifting and over time got worse. The dealer couldn't duplicate the problem(of course) and couldn't do anything because no code was being thrown. Finally, after a couple months and the car wouldn't hardly move, it threw a code. An overheat code. Got to dealer and confirmed. Tranny replaced under 100K warranty. Kept my car for 6 weeks to have tranny sent from California but they did pay for a rental. The disturbing part is a car with so few miles shouldn't have tranny problems especially when the hardest thing it did so drive a smooth highway. This will be my last Hyundai. I thought they had gotten past their quality issues but I guess I was wrong.
