2023 Hyundai Santa Cruz

Driving through my neighborhood. Went to enter a Hwy and tried to accelerate. Could only go about 25 mph. with engine speed fluctuating. Checked to see if I had hit paddles by mistake. That is what it felt like. Pulled over put in park. checked for dash notifications none. Got up to about 45, speed fluctuations again. Pulled over turned off ignition. That fixed the problem. Safety concern if traffic was heavier, I would have been rear ended easily. Was no place to pull over right away.

11/14, 2023 Drove about 2-3 miles when all warning lights on the dash came on like a Christmas tree. I was coming to a 4 way stop, both roads were 55 mph speed limits. There was a car behind me and another coming to a stop from the left. I wanted to get across the intersection to pull over and assess the situation. While trying to get across the intersection there was no response to the throttle pedal, ended up idling through the intersection at 4 mph. After getting across I pulled over and turned the truck off, let it sit for maybe a minute or so. Then I restarted and the only warning light that stayed on was the service engine warning light. The throttle showed response at that time, I started driving slowly and eventually felt it was ok to gain speed. Was able to drive at posted speed limits. 11/1582023 I took truck to Hyundai service department. 11/17/2023 Hyundai service advisor called and stated the tech support line told them to try replacing the wire harness because of erratic readings. The harness was on backorder until 11/27/23. 12/4/2023 Service advisor told me the harness was now on national backorder until 12/7/23. Again he said he will contact me when the part comes in. Truck went into service on Nov 15, 2023 and now Dec 17, 2023 tech line suggested wire harness to be replaced is still not available.

Tire size Michelin 245/50. R20. Multiple tire flats right rear vehicle has 8368 miles. Last flat was puncture in sidewall requiring replacement of tire. Suspect tire rubber faulty as appears odd color and extremely difficult to clean also has odor or odd smell when cleaning. All flats were displayed on the pressure dash warning it is unknown to me why multiple flats could be a malfunction of all wheel drive system rt wheel turning different from rest of wheels?

On 04/26/23 a lamp assy-rear comb outside Qty: 1 installed 92402-K5000, was replaced due to condensation inside the taillight. On 09/22/23 both taillights, lamp assy-rear comb outside Qty: 1 installed 92401-K5000, was replaced and lamp assy-rear comb outside Qty: 1 installed 92402-K5000, were replaced due to condensation inside the taillights. Should the condensation in the taillights cause the brake and or turn signal lights to fail this could cause a serious accident! I have an appointment at 1:00 PM at my dealership Hyundai of Anderson in Anderson, SC to have both taillights inspected for the third time, tomorrow on 10/10/2023 because of condensation inside them. I might add that the condensation has occurred when there has been no rain on the vehicle and the vehicle has not been washed. My Santa Cruz is also housed in a completely enclosed garage.
