2021 HYUNDAI SANTA FE Forward Collision Avoidance Warnings Problems

I am writing to formally express my deep concern and dissatisfaction with the ongoing quality and safety issues I have experienced with my 2021 Hyundai Santa Fe, which I purchased new in March 2021. Despite regular maintenance and careful ownership, this vehicle has presented a persistent pattern of failure—most notably involving the electrical systems, onboard cameras, and overall build quality. Specifically, the following issues have occurred: •The rear backup camera has intermittently failed for an extended period, frequently displaying a black screen or static lines, rendering it unusable. •The front camera system has now failed entirely, disabling several advanced safety features. A warning alert is permanently displayed on the dashboard and cannot be dismissed. •I was recently informed that repairing this front camera will cost approximately $2,400, a significant expense for a system that should not fail this early in the vehicle's life cycle. •The overall quality of the interior...

I was accelerating after being at a stop sign onto a major two lane road when all of the warning systems came on and the car stalled while the front of the car was partially on the major two lane road. The alarms, including the collision warning were going off, and it took me several minutes to restart the engine. I was very lucky that I was not hit by oncoming traffic. This was immediately reported to our local Hyundai dealer. They took two weeks to schedule our appointment and then told us nothing was wrong and that everything "checks out". Today, I receive the recall notice telling me the loss of power "could increase the risk of a crash" and yet they do not yet have a fix for it. This means I am paying for a car that is unsafe to use with no remedy in sight. Had...

Emergency braking comes on with no vehicles in front for 1/4 mile. Passenger front seat belt is no working properly. Caution Collision comes on sporadically. Clock does not show correct time. Stop-Start System works sporadically. A/C fan blows out defrost sometimes. Remote start does not always work or shuts off too soon. Case Manager does not return calls. Changed Case Manager but NO BETTER. Hyundai DOES NOT CARE.

While driving in the fast lane on the freeway at speed limit the car suddenly began to slow/stop, after which a warning flashed on the display that said Danger, collision imminent, or something like that. There was no one close in front of me when that happened. This exact scenario has happened three times now in this car, in the same way! I felt my life was endangered every time by the sudden and unnecessary braking of my car.

Smart Cruise Control relies on the inconsistent and consequently unreliable performance of the of the front-mounted radar. Otherwise-reasonable operation of the Cruise Control would abruptly terminate 1/3 to 1/2 of the intended use-time, illuminating the master warning light (the amber triangle with internal ‘!’) that was accompanied by either a ‘1’ or ‘2’ encircled by red and may or may not have included the Collision-Avoidance warning light. Subsequent examination of the rectangular shield in the center of the grill very rarely revealed more than 2 bug remnants. When the Smart Cruise Control was in operation it would abruptly apply the brakes when approaching or passing a truck in the lane to taffiche right. There appeared to be no similar conditions to the size or shape of the truck or trailer when these events would occur. None of these events applied to congested tr conditions, just otherwise open road. The ’21...

THE FORWARD COLLISION SYSTEM IS AUTOMATICALLY BEING ACTIVATED WITHOUT ANY CAR OR OBJECT NEAR THE FRONT OF THE VEHICLE. IT HAPPENED 3 TIMES WHILE ON THE FREEWAY AND HIGHWAY. THE SYSTEM AUTOMATICALLY SLAMS ON THE BRAKES, THE VEHICLE SWERVES A LITTLE TO LEFT AND RIGHT DUE TO THE SUDDEN APPLICATION OF THE BRAKES, AND A LARGE RED WARING INDICATOR APPEARS ON THE DASH. WE WERE NEARLY REAR ENDED WHILE TRAVELLING ABOUT 65 MILES/HR BECAUSE OF THIS. WE TURNED OFF THE SYSTEM, BUT EVERY TIME THE CAR IS STARTED, IT AUTOMATICALLY TURNS THIS FEATURE ON!! SO YOU ALWAYS MUST REMEMBER TO TURN IT OFF. WE JUST BOUGHT THE VEHICLE BRAND NEW. IF THIS ISNT FIXED, WE FEAR WE WILL BE REAR ENDED ON THE FREEWAY, OR MAKE TAIL GATERS VERY ANGRY.
