NHTSA should issue a recall for 2023 model years also as Hyundai has not addressed this issue to the fullest extent in 2023 model years.

When accelerating from a stop, my car will not go over 20 mph. It just revs up like it’s not changing gears . I have to pull over and park it. It runs fine afterwards. This does not happen all the time. Usually it happens once a month. It’s been to the dealership 3 times. They drive it around the block and tell us that they can’t replicate the problem. Therefore, they don’t troubleshoot anything and return the car to me. I’m truly scared to drive it. I wrecked twice at a red light intersection.

See attached document for complaint

While parking my 2023 Hyundai Sante Fe, I hard pressed the break and pushed the Park button. The engine revved up and the vehicle took off instead of going into park; smashing into a building. The parking block was 6ft from the building. The engine accelerated to a high enough speed that it totaled the vehicle completely out. The engine code readings after the vehicle was towed to a repair shop was P0112 and P0114. The mechanic says that's the initial cause of the accident. The insurance reps are supposed to be following up on the mechanics diagnostics currently. There were no warning lights or anything on before the issue occurred as this was a brand new vehicle with only 8,000 miles on it.

when I tried accelerate, the car jerked and then the transmission began to slip and I coasted to a stop. I cranked the car and slowly began to drive the car while it felt like the transmission was slipping. My first thought was that the transmission was low on fluid but later found that this is a sealed transmission. Luckily there was no traffic during this incident. There was no warnings lights or any warnings whatsoever.

My 2023 Hyundai Santa Fe Calligraphy with 14k miles showed a check-engine light. I had noticed some strange behavior in the shifting with a loss of power while driving at low gears. I made an appointment for the dealership the next morning. Was told today that the car needs a new transmission.

I purchased a new 2023 Hyundai Santa Fe and on multiple occasions when trying to accelerate the vehicle has failed to go above 30 mph. I have put on about 6,000 miles. When I pull over and restart the car. The issue seems to resolve. This is quite dangerous when trying to get on the highway or accelerate to pass for myself, passengers in the car and others. The dealer has not been able to repeat the issue. No warning or error codes appear. After repeated returns to the dealer, the dealer has now refused to review the vehicle without a $200 charge to investigate. I am happy to make the vehicle available for inspection.

While driving under normal conditions with vehicle in Drive, transmission shifting into Neutral with no driver input or action and the engine remained running. Transmission indicator remained in Drive, and engine would rev, without forward propulsion. This occurred three times is close proximity, within 30 minute period. Each time, shutting down the vehicle, waiting approximately 5 minutes to restart, the vehicle would then shift into Drive normally and move under power. There were no warning messages or indicators prior to or during the three episodes. Dealer was unable to diagnosis any errors, even using GDS. If the vehicle had been moving at highway speed or on a more congested roadway, this could have posed a significant safety risk to the occupants and any nearby vehicles, as the driver may have not been able to safely pull off the roadway when the vehicle lost propulsion (shifted to neutral).

My 2023 Hyundai Santa Fe have a recall to fix the trailer hitch, since that I notice some issues with the shifting with a loss of power while driving, my car is 15k miles and showed a check-engine light. I made an appointment for the dealership the next morning. After two days, I was told that the car needs a new transmission. After 3 days still waiting for the car to be fix.

Vehicle has just over 4k Miles on it. Several times I tried to accelerate and while the engine RPMs would increase, the vehicle would not accelerate. Very dangerous when turning right on a red light and when merging into traffic. I came close to getting T-Boned on 4 occasions, and rear-ended on 3 occasions. This vehicle is not reliable and puts passenger lives in danger. Today the "Shifter System Malfunction-Service Immediately" warning came on and I was not able to shift into any gear and the vehicle put itself into neutral. Looking at the forums, this has been a problem throughout the Hyundia vehicle lineup for years with the DCT transmission. I don't understand how they can continue to sell these vehicles when there is a known safety issue with the DCT transmission. I have tried to contact Johnson Hyundia in Cary NC and left multiple messages with the service dept, but they have never returned my calls.
