2020 Hyundai Santa Fe Driver Assist & ADAS Problems

The contact owns a 2020 Hyundai Santa Fe. The contact stated that while driving approximately 60-75 MPH, the Automatic Emergency Braking system engaged erroneously, almost causing a crash. The contacted stated that the failure mostly occurred while driving at highway speeds with no other vehicle nearby. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not contacted. The failure mileage was approximately 90,000.

I was driving on the highway going about 75 to 80. My vehicle will start warning me that a car was in front of me when the cars was about 3 to 4 car links ahead of me. The emergency brake will start for at least a mile down the road. Then shut off. It will happen at least 5 times on a 4 hour trip. This really need to be fix before someone get rear end.

On Interstate 95 in Virginia, multiple times, going ~68-70 MPH the vehicle automatically applied the brakes causing an unsafe situation with a momentary loss of control. Multiple times this has happened with no other vehicle or obstacle in front of, or beside me. It has happened now for no reason causing the loss of control of the vehicle. We have reported this to Hyundai and they cannot find any fault code, or record of the incident. Our understanding is that this is a widespread problem with this vehicle and system, but also includes other vehicles with the same technology. We are afraid this may end up causing serious damage, injuries or fatality(ies). We have asked Hyundai to turn the system off, and they have refused. They have no solution, and we have spent time and money on this.

This vehicle has the Accident Avoidance system which is great until it snows or there's a heavy rain then you get lights on the dash and the Accident Avoidance system and cruise control turn off because the sensor gets covered with snow or heavy rain. I spoke with a service technician who said it's a know issue but there are no fixes at this time. What the sense in having a safety system that shuts off when you need it the most in bad weather. Once you clean the snow or ice off the sensor area the lights go out. It happens any speed.

I was pulling out of a sidestreet and realized a car was coming and used the brake. The Automatic Braking system activated and VIOLENTLY stopped the car. I was only going about 5 miles an hour but the tremendous force from the Braking system caused my rotator cuff and my bicep to tear. It cost me thousands to pay for surgery and physical therapy. I am very worried about all the injuries that this system causes. I have since had the dealership turn it off. I can not risk being injured like that because the car thinks that there will be a collision when I know that my manual braking was sufficient. There was no chance of any accident. I had Hyundai (case # 20962390) inspect the car & they claim (after 4 different inspections) that there is no issue with the system. They also claimed that it wouldn't activate at 5mph but I know that is not true. So if it works correctly, how many people are injured? Before you mandate that the car stop at 65mph, you need to gather more info on how many injuries have occurred.

We are experiencing exactly what is listed in HYUNDAI TSB #21-BE-005H: intermittent abnormal camera image display conditions on the instrument cluster when the turn left signal is turned on or the radio screen when transmission is in reverse.

Blind Spot System randomly fails to detect vehicle on right side, I have videos of failure. Dealer unable to find problem cause, contacted Hyundai customer service, waiting for response.

The adaptive cruise control, automatic emergency braking, and forward collision avoidance systems in my SUV have been defective since purchase in June 2019. Hyundai has replaced the radar sensor but the dealer is waiting on a part to calibrate it which has been on indefinite backorder. I have waited over a year to have this issue fixed. I am paying a car payment which includes these features as the total cost and would like reimbursement for the cost difference, for the issue to get escalated and fixed, or the dealer to offer a vehicle buyback so that I may purchase a vehicle with no defects.

THE 2020 HYUNDAI SANTA FE FOWARD COLLISION AVOIDANCE ASSISTANCE SYSTEM IS NOT FUNCTIONING CORRECTLY. WE HAVE CONTACTED HYUNDAI ON MULTIPLE OCCASIONS WITHOUT RESPONSE. THE SYSTEM IS BRAKING IN THE MIDDLE OF THE ROAD WITHOUT AND CAUSE. NO CARS ARE IN ANY PROXIMITY AND THE CAR BRAKES IN THE MIDDLE OF THE ROAD. THIS HAS OCCURRED TWICE WITHOUT WARNING IN THE LAST SEVERAL MONTHS. DEALERSHIP HAS NO ANSWER WHEN WE TOOK THE CAR IN. HYUNDAI CONSUMER LINE DOES NOT RETURN CALLS. IT IS AN EXTREME DANGER WITH OUR SON DRIVING CAR. REAR END COLLISON WILL HAPPPEN IF THIS CONTINUES.

HYUNDAI 2020 SANTA FE LIMITED BLIND SPOT COLLISION-AVOIDANCE ASSIST (BCA) SYSTEM WHEN SET IN ACTIVE MODE AND UNDER THESE CONDITIONS ITS ACTIVATION IS EXTREMELY DANGEROUS: IN THREE (3) OR MORE LANES OF TRAFFIC. IN NEITHER OF THE OUTER LANES. PASSING A TRUCK IN THE LANE ON THE IMMEDIATE RIGHT. VEHICLE(S) IN THE LANE ON THE IMMEDIATE LEFT. VEHICLE(S) IN THE LANE ON THE IMMEDIATE RIGHT. AT SPEEDS OF 50 ' 70+ MPH. WHEN THE SANTA FE APPROACHES THE FRONT END OF THE TRUCK, THE BOW WAVE OF AIR FROM THE TRUCK PUSHES THE SANTA FE TOWARDS THE LEFT LANE LINE ACTIVATING THE BCA, WHICH VIOLENTLY JERKS THE SANTA FE TO THE RIGHT. WHEN THIS OCCURS AND THE SANTA FE IS MOVED VIOLENTLY TOWARD THE RIGHT LINE LANE, THE BSA DETECTS THE TRUCK (OR OTHER VEHICLES) IN THE RIGHT HAND LANE, AND VIOLENTLY JERKS THE SANTA FE TOWARD THE LEFT HAND LANE. UPON DOING SO THE SANTA FE BSA AGAIN DETECTS VEHICLES IN THE LEFT HAND LANE AND AGAIN IMMEDIATELY JERKS THE SANTA FE TOWARD THE RIGHT HAND LANE. THIS ACTION CONTINUALLY OCCURS UNTIL THE DRIVER FORCIBLY REGAINS CONTROL OF THE STEERING WHEEL, AND/OR DEPRESSES THE BRAKE. THIS REPEATED VIOLENT JERKING THE SANTA FE BACK AND FORTH ACROSS THE LANE IT'S IN HAS VERY NEARLY CAUSED AN ACCIDENT IN AT LEAST TWO (2) OCCASIONS (OCT 27 & 28, 2020) UNTIL WE FOUND THAT THE BCA COULD BE DEACTIVATED AND SET TO WARNING ONLY. THIS VIOLENT ACTION OF THE BCA SHOULD BE REMOVED FROM THE SANTA FE VEHICLE TO PREVENT ACCIDENTS.
