2023 Hyundai Santa Fe Fuel System Problems

While driving on the interstate at 70 mph, your vehicle's fuel injectors suddenly failed, causing you to lose engine power without warning. This is a serious situation since it happened at highway speed. The repair will likely involve diagnosing and replacing the failed fuel injectors.

Your fuel injectors are malfunctioning, causing your engine to misfire, run rough, and smell like gas. The dealer replaced one injector in early December, but the same symptoms returned and the check engine light came back on multiple times in late December and early January. The dealer says they won't replace the other faulty injectors until they completely fail, and their safety advice is for you to visually inspect your car daily before driving. Fixing this will require the dealer to replace all failing fuel injectors and diagnose why multiple injectors are failing prematurely.

Stopped at left turn lane light. Light turns green and vehicle engine revolutions increase as I press on gas pedal but car does not move. Cars behind me lean on their horns and take evasive maneuvers to go around me. Car finally goes very slowly and transmission disengages in middle of left turn leaving vehicle in middle of intersection with oncoming traffic. Luckily everyone stopped and vehicle very slowly moved through the intersection to side of road. Vehicle is brand new and in my possession less than 48 hours. Vehicle is at dealership for troubleshooting.
