What 199 owners told NHTSA about the 2023 Hyundai Santa Fe Hybrid

There is an extreme amount of hesitation/delay from when you depress the accelerator and when the vehicle accelerates. I have had multiple incidences (both from a complete stop and while already moving) where I depress the accelerator and there is a concerning amount of lag time before the vehicle initiates movement. This has almost led to multiple accidents. This defect happens in all drive modes. This issue appears to have gotten worse over the time we have owned the vehicle. We did not notice this issue earlier on. We bought the vehicle brand new in Dec. 23.

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. I have contacted my local dealer, they said they have seen on another vehicle, was not sure of outcome, having service manager call me. Lots of complaints online forums of similar issues.

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.
