2020 HYUNDAI SANTA FE Forward Collision Avoidance Problems

*Problem Parts:I only could check 1 box- should be Brakes and Steering too *ADAS: Lane Keeping Assistance too Over the course of two days, my 2020 Hyundai Santa Fe experienced a serious electrical and safety system failure. It started with the blind spot monitoring lights flickering in the side mirrors and warnings for Forward Collision Avoidance (disabled), ABS, Electronic Stability Control, Downhill Brake Control, Parking Brake & Brake Fluid (blinking red). The rearview camera failed and the screen remained on the radio display when in reverse. The Lane Keeping Assist Indicator shifted from white/green to orange. The next morning, I had trouble opening the vehicle with the key fob. Auto Hold, Master Warning, Forward Collision, ESC, and Downhill Brake Control lights were now steadily on. The MPH numbers on the dash were blurred, and a message appeared saying “Put in P” even though the vehicle was already parked. The accessories light came on, but the engine would not start. Interior lights continued to work. I had to manually open the car and start it by pressing the fob to the button. While trying to exit a parking garage (where a tow truck couldn’t reach me), more warnings appeared: AWD, Low Tire Pressure, Malfunction Indicator (not engine), and Power Steering. I felt tightness in the wheel and had to pull over. The temp and gas gauges dropped to zero along with the RPMs. I have a newer car battery and recently replaced fob batteries, so this was not a simple battery failure. I’ve reported the issue to Hyundai Consumer Affairs. No recall appears under my VIN, despite similar failures being widely reported in this model. I’m a single parent who typically drives with two young children, including one with serious medical needs. I rely heavily on this vehicle for medical travel. The vehicle has since been towed to a Hyundai dealership for diagnostics. This is a serious safety concern and could have led to a loss of control or failure in an emergency situation

Frequent intermittent dash warning lights, no speed indicated, no tach indicated, cycles through warnings of safety systems malfunctioning. No lane departure, no adaptive cruise, no cruise, no forward collision warning, no blind spot warning. The disabling of these systems puts all drivers at risk. Dealership replaced front camera and windshield to fix this issue. Not fixed, continues to alarm at random times while driving.

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.

Numerous different occasions since I bought the vehicle this year in March 2023 when on highway, side streets and even in parking lots with nothing, no cars no objects or humans in front or behind the vehicle my forward collision warning and rear end collision warning has came on which caused the car to break on its own and it is a safety concern. I have been to the dealer numerous times since I’ve bought the vehicle and currently have reached out to Hyundai Motors of America and pretty much got told to suck it up nothing they can do for me as the computer isn’t showing any codes or issues my car has now been at dealership where I bought it for 2 weeks now and no resolution besides come get the car and figure it out on my own and as a single mother with a child with disabilies I don’t know what else to do.

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.

I was driving on an interstate highway at approximately 75 mph. I had cruise control activated. Suddenly the car dramatically slowed down, accompanied by rapid beeping noise. Luckily, there was no one close behind me.

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.

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.
