2017 Hyundai Santa Fe Sport: harsh or hard shifting

Filed Oct 15, 2026 · Transmission · CO

After we had the Hyundai 9C2 recall completed a few weeks ago, we immediately had rough shifting in our Hyundai Santa Fe Sport driving off the lot. Problem has continued since, and is most notable after cold start/once the car has sat for an extended period of time. Hyundai has released a Drivability Information on 5/18/26 regarding the known issue, but our Dealership was unaware. The Dealership recommended replacement of the Transmission, despite my explanation that the issue began after the installation of the recall fix.

Service Campaigh 9C2 Following completion of Service Campaign 9C2 (Theta II Emissions Improvement), certain vehicles may exhibit a brief hesitation or rough shifting condition during cold start operation. My 2017 Hyundai Santa Fe sport has severe loss of power and rough jerky transmission after the update. This condition will definately cause unsafe driving and vehicle engine and transmission damage. Hyundai corporate and local dealerships indicate no remedy for this situation. Dealer also indicated that Hyundai corporate may not release a new software update to fix the issue. This is unacceptable.

On February 24, 2026, I had the 9C2 software update. My vehicle was being checked for oil consumption. Since then I have had issues with it hard shifting when first starting to drive and sometimes after I've been driving a while. This has continued miles down the road, sometimes over thirty minutes after driving. It also just feels continuously like it is not driving smooth. This only started after the update. I contacted HMA. The first person on my case (Gurvinder) told me I needed to return my car, not to drive it. I had bronchitis, so I did not immediately do that. The next person "Rainey" told me it is a KNOWN issue and they are telling people to warm their cars up for around 3 minutes, and it will be fine. I'd done that, and even driven longer than that. I told him that. I took my mother-in-law home from church miles from there after collecting her at the church door, etc... Getting to the hill at to her home, I didn't think it was going to get up it. Often I don't think I'm going to get out of my driveway, a dangerous driveway in a curve. He wanted Krause Hyundai to contact HMA Engineer. When I was at Krause, they didn't know how to get ahold of HMA Engineer. Dalton also said they can't back the update out. I'm on my third HMA Case Manager. She keeps changing what I've told her is wrong in the emails, I don't think she knows anything about cars. She won't listen when I say I spoke to Dalton at Krause; she keeps speaking to John. [XXX] said they can do diagnostic, but it will cost me. I refuse to pay as [XXX] and Gurvinder had months before wanted me to take it back to get fixed, and Rainey wanted Krause to contact the engineer. It is a known issue with a letter written by Hyundai. Getting a diagnostic code reading performed is not going to help. I'm afraid my vehicle will lose power on the road and I will be struck.

My 2017 Hyundai Santa Fe sport has never had any issues until last Friday when I took my car to the dealership for regular maintenance (oil change, tire rotation) as I always do. They also performed a software update for recall campaign 9C2. Every day since, when first starting the car after it’s been resting for a while, I’ve experienced a jerky transmission and rough shifting for a first couple minutes of driving. Hyundai has acknowledged they are aware of this issue related to the campaign and the dealership said they’ve had many customers complaining of the same problem following the recall update. However, Hyundai has offered no resolution, other than recommending the car warm up for 13 minutes after starting. Hyundai needs to correct the issue they caused, as my car was perfectly fine before it was serviced and now it’s not performing properly.

Transmission shifting is erratic. Stumbles/slams into gear 90% of the time. Shifting is felt throughout entire car. Transmission upshifts way to early when slowly accelerating or driving at low speeds. Car could be going 20 MPH and has already put itself in 4th or 5th gear. Then when you try to accelerate, the car bucks and will eventually slam into the lower gear that it should have been in. Makes it very difficult and uncomfortable to drive in stop and go traffic. Transmission doesn't downshift properly either. You must come to a complete stop before making a turn onto a street. If not, the car will not downshift to the correct gear and when you try to accelerate, the car will start bucking and eventually slams into the appropriate gear. I took the car to springfield hyundai in springfield, pa to have it looked at. After waiting there for 3 hours, they told me that they couldn't replicate the issue I was complaining about, but performed a "software update" that may help. I'm still not sure how a car that was purchased only a month prior, from a hyundai dealer, had a "software update" that wasn't performed before I purchased it. The 14 year old honda element that I traded in on this car shifted and drove smoother.
