2024 Hyundai Santa Cruz

WHILE DRIVING ON I-81 UP A STEEP GRADE, TRUCK SUFFERED A SUDDEN POWER LOSS, WITH SPEED DROPPING TO 35 MPH FROM 65 MPH. ATTEMPTS TO REGAIN SPEED FAILED AND IT FELT LIKE TRUCK DOWNSHIFTED TO A LOWER GEAR. 35 MPH CONTINUED UNTIL I DECIDED TO USE TRUCK CRUISE CONTROL TO ATTEMPT TO GAIN SPEED. I WAS WORRIED ABOUT TRACTOR TRAILERS HITTING ME DUE TO LOW SPEED. FINALLY GOT VEHICLE TO 65 MPH BUT WOULD NOT GO ABOVE 65 MPH. RODE THAT WAY FOR 100 MILES ( TRIP HOME WAS ~ 200 MILES) FINALLY IN LIGHTER TRAFFIC WHEN I HAD TO BRAKE, I TRIED TO USE GAS PEDAL TO MAINTAIN SPEED.AND IT WORKED. RODE THE LAST 100 MILES NORMALLY. I WAS AT GREAT RISK WHEN TRUCK WENT FROM 65 MPH TO 35 MPH. THIS IS THE SECOND INCIDENT VEHICLE SUFFERED IN THE LAST 2 MONTHS.. DEALER WAS NOT ABLE TO DIAGNOISE PROBLEM. VEHICLE HAD NO WARNING LAMPS TO WARN ME IN BOTH INSTANCES.

Upon starting the vehicle is doesn't act normal and when placed In drive it feels like brakes are applied and it doesn't want to hardly move even when pressing the throttle all the way down. This has also happens a couple times when at a stop and have to pull over and turn the vehicle off and restart. My so. Drives this vehicle and I feel this is a huge safety concern if he is able to get the vehicle moving and can get to a safe spot to shutdown and restart.

As I was attempting to accelerate at a stop light, once I got to 10mph I lost all power and the vehicle appeared to be in neutral, even though it was in gear. The engine just revved and would not go any faster. It appeared that the transmission just completely slipped out of gear. I had to figure out a way to exit the road as I was in full rush hour traffic. When I re-entered traffic to try again, the same thing happened and I exited into a side street neighborhood. The third time, the car did accelerate although it was rough shifting. This problem is extremely unsafe. This is a brand new car and unacceptable. When I researched this issue online, it appears to be a very common issue in the 2022-2024 Hyundai Santa Cruz’s. I hope that this will be investigated.

On one occasion on interstate at highway speed during summer, dry conditions I was driving at approximately 60 mph and was not accelerating while maintaining average pace in traffic. For no apparent reason the engine lost all power. I was forced to drift over in a hazardous manner to reach the right shoulder. When the power was lost the engine was still on and operating, multiple presses on the accelerator did not provide any power or increased engine noise. Once stopped I checked that the truck was still in Drive gear, engine was on and parking break or assist was not engaged. The drive Mode button was in the Smart setting. I placed the truck in park and turned off the engine. I turned the truck back on and placed it in drive and the truck began operating normally. I feel this is a safety hazard as an unexpected loss of power could cause a collision or loss of control under driving conditions. I will advise my dealer, dean hyundai ballwin mo when taken for oil change 12/9.

On 2 separate occasions on the highway at 55+ miles per hour during daylight dry conditions summer temperature the following safety hazard occurred; A car approached the rear of my 2024 hyundai santa crux night 2.5L. while on the highway. The approaching car likely at 25’ and closing when the santa cruz engaged the Rear Collision Emergency Brake system. It engaged for only a few seconds, but there was a noticeable brake check event, a severe grinding noise and the red rear collision warning system flashed on the driver instrument panel. I am asking my dealer to check system codes and software when taken Dec. 9 at dean hyundai ballwin mo.
