The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving 50-65 MPH, the vehicle stalled and decelerated to a complete stop with several unknown warning lights flashing on the instrument panel. The vehicle was restarted and operated normally. The contact drove the vehicle to the dealer where several fault codes were reset. The contact continued to experience the failure and returned to the dealer where the dealer replaced the throttle assembly and later replaced a front camera with a hard code. However, the contact stated the failure persisted. The vehicle was with the dealer but was not repaired. The manufacturer was also notified of the failure and provided the contact with a case number and a case manager to assist with the failure. The approximate failure mileage was 1,700.

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.

While merging into the highway at approximately 49 to 52 mph, acceleration was applied to merge into the highway between moving vehicles. The vehicle responded by greatly increasing the rpm but not applying the power to the wheels. The engine revved up with very little acceleration. After 5 to 8 seconds, the power was finally transferred to the wheels and the vehicle sped up. The vehicle behind me had to apply the brakes since I basically cut them off. This was the second incident of this type.

This same scenario has happened 3 times since I purchased this vehicle - first event at mileage of 6273, 2nd event @ 7586 miles, and 3rd event @ 12,506 miles. All events were the same - while driving, dash board light start to flash and the vehicle looses all ability to accelerate. For each event, we have been able to coast out of traffic, turn the car off & restart. Once the car is restarted the acceleration works again, but the check engine light remains on along with an error code of P065312 Possible Power Train Issue. We have been very fortunate each time that we were on a road where we were able to coast out of traffic, but if this happened on a busy Interstate or Hwy traveling at high speeds we could have been rear-ended. The vehicle has been to the dealership twice for service and no problems have been found. The vehicle will be returned to the dealership tomorrow for 3rd service attempt.

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.

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.

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).

Car was purchased January 21st had 3000 mile on it when service was needed for these issues. On march 23rd as I started driving my car wouldn't go above 30 mph, when pressing on the gas pedal the car wouldn't accelerate, the rpm gage would go to 4 but engine wouldn't make noise car wouldn't speed up. I put the car in park and back in drive with no improvement. I pulled off at a gas station restarted the car and it was fine. During this time the auto on off button was orange on the cluster which I had never seen it that color before. Was looked at by the dealer but wasn't reproducible. Not sure the cause, but safety was in jeopardy due to not being able to go with speed of traffic. Also a couple weeks after purchase brakes began to squeal, took car to dealer on march 28th was told brake pads were sanded and cleaned, upon leaving dealer brakes continued to squeal, car is now back at dealer, supposedly needing front rotors and pads replaced. Dealer won't drive car until rotors replaced. Safety was in jeopardy cause of possible brake failure and resulting accident.

2023 Hyundia Santa Fe bought brand new from the dealership. During the course of the last month and a half the vehicle has done things with unknown origin. The panic alarm will randomly go off when the vehicle is turned off, no one is in it, or even near it. By locking the vehicle with the remote, the alarm will tend to go off about 20-30 seconds after the vehicle is locked and will sometimes not stop until the vehicle is restarted. The transmission will shift very roughly almost to the point that it feels like you are driving a manual transmission vehicle. The transmission lags in gears between 60-70 miles per hour and you feel a very rough back and forth shifting with in the transmission. Next the emergency break would engaging and then not releasing or reengaging when parked on a hill, flat service or anywhere. The break light on the dash would light up, blink, then it would go off, making it unknown if the emergency break was acting engaged or not. The dealership I purchased it from did replace the EMS module along with breaks and rotors on the vehicle. The auto shut off or the idle shut off will also randomly work, and not work. it will cut on and off even if the button is pressed to shut it off or prevent it from coming on. Now the air condition, along with the heat and heated seats has started to not work, randomly cut on, will not cut off etc. While driving i have had the heated seats turn on, along with the heat and not go off, nothing would cut off until the vehicle was physically turned off and restarted. No codes have ever been displayed or found by the dealership.

Stopped at left turn lane light. Light turns green and vehicle engine revolutions increase as I press on gas pedal but car does not move. Cars behind me lean on their horns and take evasive maneuvers to go around me. Car finally goes very slowly and transmission disengages in middle of left turn leaving vehicle in middle of intersection with oncoming traffic. Luckily everyone stopped and vehicle very slowly moved through the intersection to side of road. Vehicle is brand new and in my possession less than 48 hours. Vehicle is at dealership for troubleshooting.
