The warning light saying that the emergency braking system is temporarily disabled keeps coming on and off multiple times a day and it disables the adaptive cruise control when i an driving in cruise control. it happens while vehicle is in motion in all kinds of circumstances and weather and have taken car to dealer 3 times without any solution. have tried cleaning sensors multiple times. dealer has seen it happening twice in a 10-15 minute test drive documenting it. hyundai consumer assurance has not resolved the problem either. it has been happening since december 2018. it was not happening at all for the first 14-15 months of ownership. it happens at various speeds.
Tl* the contact owned a 2018 (na) hyundai santa fe sport. while driving 35 mph through an intersection, the power steering seized and a red steering wheel and exclamation mark illuminated. the contact was able to pull the vehicle over to the side of the road and it was towed to the dealer. the dealer (hyundai of new port richey 3936 us-19, new port richey, fl, 34652) diagnosed that the vehicle was transmitting data to the steering mechanism; however, the steering mechanism was unable to read and correspond. the steering mechanism needed to be replaced. the vehicle was repaired. the manufacturer was not contacted and made aware of the failure. the failure mileage was approximately 200.
Within days of taking delivery, the vehicle would take 3-4 seconds to accelerate from a stop, and would not fully accelerate until almost 10 seconds later, creating a huge safety issues for times when speedy acceleration (at intersections, close calls, etc.) was paramount. from there, the infotainment system glitched out and would not turn on until i restarted the car, and it had issues with voice commands intermittently, defeating the purpose of a hands-free device (once again creating more safety concerns). most regularly, the vehicle would struggle so badly to accelerate from 0-40, and 50-60, and would redline, causing huge stress and strain on the vehicle's power train. hyundai told me "this is normal" which it is not. this happened daily at intersections, back roads, and on highways--it did not discriminate. i had several near misses when the vehicle refused to accelerate. in fact, just today, i went to accelerate through a turn and had the gas pedal floored because it would not accelerate past 10 mph. it took a full 20 seconds to get up to speed. this has happened in all driving modes: eco, normal, and turbo.
