Automobile approached and stopped at stop sign. When accelerator pressed to continue, car remained in place, shuddering (as if transmission were slipping),and making significant noise. Car would not shift out of gear, nor move. Operator shut off car and then restarted car. Car started normally and was in park without shuddering. Expectations at busy intersection was that it was my turn to move and did not do so, creating doubt on what my car might do next. Traffic flow was briefly confused and some drivers honked and were unsure what they should do. This could have caused an accident with an impatient driver re-ending my car, or with others going through the intersection "out of turn" and unclear on my situation. No lights or other warnings were displayed before this incident. It has not re-ocurred. I brought into the dealer who had no other reports of this type of behavior.

While travelling at highway speed, attempted to accelerate to pass slow traffic. Rather than accelerating, the car hunted for a gear, and wouldn't shift properly. The car downshifted but engine would not go beyond 4000 RPM and speed remained the same. This has happened multiple times. By unexpectedly not accelerating, this created a risky situation by not allowing car to pass slower traffic as expected creating a potentially dangerous situation. (Video of one of the instances exists). No warning lamps, messages or symptoms occurred up to that point. Car was brought to dealer but since no codes were contained in the computer, they said there was no trouble found.

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.

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.

Occasionally the cruise control when accelerating will exceed the set speed and continue to climb and I will be going 20 miles faster than the set speed and climbing. The only way to sop this is to turn cruise off, slow down and restart. My thought is it happens after I have disengaged the cruise and then when safe reengage which is done by pressing the switch straight down. In my previous vehicles I would push the control up. I may be doing this by accident and giving the system an unknown command. Whatever I am doing to create tis situation is too easy to do and creates a safety issue. this has happened multiple times.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that the RPM would be elevated while the vehicle was idling. The failure recurred while the brake pedal was depressed. There were no warning lights illuminated. The failure recurred approximately 3-4 times within 30 days. The failure recurred approximately 15 times within 6 months of owning the vehicle. The contact took the vehicle to the dealer who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 12.

Driving on highway with cruise control selected to 80 mph. Left signal is applied to travel to left lane to pass a semi trailer. When the vehicle is half way into the left lane, the automatic system applies hard braking even though the semi trailer has not been detected as too close. Vehicle slowed to 74 to 75 mph before cruise control was turned off. Vehicle behavior is a total surprise to vehicles following since the braking is unexpected on a clear road. Repeated the symptoms several times. This braking does not occur if the vehicle ahead in the right hand lane is an automobile. This only occurs if it is a large vehicle such as a semi. Moving quickly or slowly to the passing lane affects the total time the braking is applied. The slower the movement, the longer the braking is applied. Repeated this behavior at 75 mph and 70 mph with similar results.

I purchased this SUV new and noticed an issue with the automatic intermittent wipers. The dealership has replaced the windshield sensor and issue is now unreliable at best. Service department told me to simply wipe the sensor off or pour water onto the sensor to get the wipers to work. That seems to work for about 3 wipes and then stops again. Also, the driver seat changes position by itself while driving, and the advanced cruise control failed to provide any braking and almost caused me to rear end a stopped car in freeway traffic. Additionally the advanced braking system does not work at all... I had the salesman check the settings and they are turned on, but do not provide any braking function. The alert system does provide a warning if a car turns a corner in front of me, but fails to take any action.
