2022 Hyundai Santa Fe acceleration problems

Filed Aug 29, 2026 · Acceleration, Transmission · TX

On June 20 2026 at 2:07pm Central Time there was a check engine light displayed on the dash of my vehicle 2022 Hyundai Santa Fe Calligraphy, while it was parked in the garage of my home and was just powered up. I had then performed the vehicle diagnostics test (pictures attached) that showed that there was an issue with the 'Transmission Control System' with detail that a full system check is recommended and to schedule an appointment with a dealer. I had later proceeded to contact local dealer 'Huffines Hyundai McKinney' for service as I was due for an oil change anyway. As I was driving the vehicle from my home which was about 13 miles away from the dealership, I noticed that the vehicle had great trouble shifting from 1st gear to higher gears, that the speed would be 20mph or lower no matter how much the accelerator was pushed and I had to drive very carefully in traffic due to the low speeds. I was told at the dealership by 3pm that day that there were no active recalls on my vehicle, that the transmission related recall that was showing up on google search for that DCT code wasn't specific enough to my vehicle and to book an appointment for vehicle diagnostics and transmission repair/replacement at full cost to myself. The multi-point inspection report after oil change showed nothing about the check engine light issue or that the issue was even diagnosed by the dealership. From that day until today Aug 29 2026, I've noticed that the vehicle still has trouble shifting from the 1st gear, that the vehicle drives normally when increased time is allowed between power up and start of drive (~2min of engine running idle) and that the check engine light reappears after a trip of quick power up and drive. There was atleast one instance where I had to pullover onto the shoulder to avoid high speed traffic while driving in the right lane.

Vehicle began to display Front collision avoidance system error/ radar blocked. This also disabled the 'smart' cruise control features. This happened any time the cruise control was engaged and we encountered traffic. The unit was in the dealer's service department for a week, and the front radar module was replaced and reprogrammed under warranty.

I was driving at approximately 65 MPH using the advanced cruise control system. Randomly, the system disengaged and I started getting 2 MIL warnings on my console. MIL warning 1) was "Check Forward Safety System" and 2) warning the advanced cruise control parameters are not met due to warning 1. A few minutes later, I received a message on my Hyundai Blue Link app showing DTC C162078. After researching this DTC, I found that there are hundreds, if not thousands, of other drivers that experienced this same/similar situation -- unexpected loss of advanced safety features and smart cruise control features. In fact, Hyundai published a technical bulletin for another model with the same issue. The loss of these functions places an unexpected safety risk to the driver if this issue occurs when there is other traffic present. My vehicle was involved in a frontal accident once about 1.5 years ago and this issue has never occurred. This is the first instance of this issue since I purchased the vehicle brand new from the dealer.

Vehicle would not shift when accelerating on gas pedal while driving, rpm’s went up to 5,000. Had the car towed to closest dealership and they haven’t looked at it. They stated they are unable to assist me with a rental car. I am home alone with 2 children and cannot go to work. There is a transmission recall on the 2022 Hyundai Santa Fe with the exact problems the car has been having. Recall #236, campaign #22V746000. I called the recall consequences customer service # and they stated they were unable to help me until the dealership looked at it. The problem started in fall of 2024 and I took it into the dealership first on 11/5/24 and again when it continued the problem 11/14/24. The 11/14/24 visit they performed a software update and the car shifted smoother in Smart Drive Mode only. On Friday, 3/14/25, while driving home from work, the car would not shift at all when pressed the gas turning into traffic. I turned on my hazard lights and pulled into a parking lot. I called roadside assistance and had the vehicle towed to the dealership.

My vehicle made 3 ringing sounds and began to decelerate from 67mph to 0 in less than 2 minutes. I had to pull over quickly to avoid getting rear ended. This incident happened twice already. I took it in to the dealer and they were not able to recreate what happened. This occurrence happened 2weeks ago.

Middle of May 2024 car begins to feel like it's shifting when accelerating and stopping. Nothing found by Hyundai Service Dept. Lakeland. On apx. [XXX] while driving stepped on gas pedal and felt no power. Kept pumping the pedal & car started jerking. Managed to get to light and get in left lane to turn into plaza honking horn. Car slid to a stop at entrance. On apx. [XXX] my husband was driving home and same thing happened. Managed to slide car into our driveway. Both times the car had to be towed to dealership. Two fuel injectors have been changed and when I asked them to change other two they said warranty would not allow. Worst case scenario is if this happens on the interstate traveling at 75 miles per hour. Not only could we be killed but others. Both times there was no warning lights or any other warning. The car just started jerking and lost power. It can very well cause a car to rear end us and a multiple car chain reaction hurting or worse killing others. I am filled with anxiety every time I take the car out for errands. I also saw a similar incident reported in the Better Business Bureau here in Tampa by another person. I reported my incident to Hyundai Corporation by phone and email and asked the rep to reported it to her superiors to see if they could just please let the dealership replace my other two fuel injectors & I was told they could do nothing. The dealership has told me several times the injectors must fail before they can replace. Apparently, the cost of the injectors is more than someone's life.

Ref the federal safety agency TRACKING # 11557625 Vehicle broke down again within 5K miles and 45 days of prior repair referenced in above case. Similar conditions, highway speed, bucking and vibrating, loss of speed control, no warning. Subsequent repair confirmed same issue (fuel injector) as original breakdown/repair and my initial notification to the federal safety agency.

Vehicle began to shake, buck and emit a grinding noise while traveling on highway resulting in loss of speed control and associated fear. Check engine light appeared simultaneously. No prior indication of a problem. Managed to limp to next exit via shoulder. Had car towed to dealer as warranty was still in effect. Problem was diagnosed as fuel injector failure and repaired. Learned it is a common, recurring issue with Hyundai 4 cylinder engine. Not unusual to have multiple failures per vehicle. Hyundai is only authorizing repair/replacement upon individual failures, not pre-emptive even though common and recurring. Confirmed this is a common, recurring issue across Hyundai via our local mechanic and internet info. Vehicle has now experienced a second failure and is being towed to dealer.

I had previously filed a complaint and received an issue number 11494975 I have not been able to retrieve any information related to this number. In any event I am constantly having problems with acceleration, stalling, the car puts itself in Neutral, and on occasion has completely turned itself off at a light or while driving. I do have a video of the acceleration problem and revived an email back from Laura Nelson. This is a very serious safety issue. Hyundai is not responding to following up. I also took it to an outside mechanic to put in the computer and got a general code so there is a problem somewhere. Thank you Susan Piller
