On [redacted] I was on [redacted] in Houston, TX southbound in the Woodlands area when my vehicle warning light for overheating went on. I pulled over on [redacted] and contacted Vehicle Assistance and the vehicle was towed to my dealer, Northwest Houston Hyundai. There was damage to a tube in front of the radiator and a/c condenser. The damage to the tube was approximately 1/16 of an inch in diameter and supposedly was caused by debris entering through the front grille which is designed like a large egg carton. The dealer spokesperson informed me that they had seen many vehicles like mine (2023 Santa Fe) with the same type of damage. I have been trying to settle this with Hyundai but they feel it is normal road damage and that the wide open grille design that allows it is not their problem. …
Several times lately of extended crank. Saturday evening, car had been parked for 4 hours, did remote start and had extended crank of about 2 seconds. Car ran for about 3 minutes before we left. We left home and hit main road, tried to accelerate and vehicle seemed to go into limp mode. Would keep cutting the fuel out if tried to accelerate even above 40 mph. No check engine light came on. Put in neutral, could not get above about 3500 rpm. Vehicle was in smart mode where decides which mode to be in (normal, fuel economy or sport), when would try to accelerate it would try to change to sport as it knew power was not there. Was on a 6 lane highway and could not get up to speed. Finally was able to pull to side of road, shut engine off, waited a few seconds, restarted and issue went away, still no check engine light. …
The purchase price was $35,800. As of today, I have paid a total of $24,590. The vehicle has a manufacturing defect that has significantly impacted its performance. The engine has been problematic, as it appears to be consuming oil, and it often fails to start on the first attempt, requiring me to press the button multiple times. The most concerning issue is that the car can unexpectedly shut off while I am driving. Additionally, there is an abnormal noise coming from the engine. I consider this situation serious, as it poses a significant risk to my safety. These symptoms appear on January 13/2025. I want to emphasize that I have completed all scheduled maintenance on time. I filled out reports regarding this issue, and I have attached two reports that confirm the vehicle is consuming 2 quarts of oil per 1,000 miles, vehicle is consuming oil due manufacturing defect. …
On two separate occasions, I was a stop light in high traffic. I was unable to drive my vehicle when the light turn green because of no power. A message display prompting me to "shift to P or N to start engine." Unfortunately, that didn't work. I had to sit there for a few mins, signaling other motorists to go around me. Eventually, I had to restart my vehicle. I panicked because I felt unsafe as I was blocking traffic. I took my vehicle to the dealer and was told that there were no code after the diagnostic test but yet the technician told me the door on the driver side is not aligned and I need to take it to a mechanic. I never got any alert that my door is open so that diagnosis didn't make sense. I took my vehicle le to the mechanic to check the alignment of the door who in return told me that there was no issue with my alignment. …
