2020 Hyundai Santa Fe Driver assistance Problems

I am reporting severe safety risks and inspection fraud on my AWD 2020 Hyundai Santa Fe (VIN: [XXX]) caused by Universal Hyundai in Orlando. Inspection Fraud: The dealer falsified safety metrics, marking my brakes as a failing 4mm to push a $659.90 repair (RO# XXX), then passed those exact brakes at 5mm eleven days later (RO# XXX). Tire Malpractice: Mechanics over-inflated my tires to a dangerous 39 PSI and botched the alignment. This caused structural tire belt separation and severe sidewall bulges. The rear tire has suffered rapid, catastrophic deflation, dropping flat to 14.5 PSI and down to an empty 5.5 PSI. Crash & Drivetrain Risk: Operating an All-Wheel Drive (AWD) vehicle with a rapidly collapsing tire and asymmetric alignment forces the wheels to spin at mismatched speeds, creating severe friction that is destroying the internal powertrain transfer case and causing an immediate highway blowout crash risk. The service manager admitted "human error" and issued a full refund but banned my vehicle to avoid an audit. Hyundai Corporate has been notified under Case #XXX but has delayed resolution. Active consumer fraud file logged with the State of Florida under Case XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle experiences severe, intermittent, un-commanded steering inputs from the Lane Keeping Assist (LKA) system at highway speeds (55-70 MPH). The steering wheel violently jerks toward adjacent traffic lanes/shoulders without operator input, lane drift, or warning, requiring immediate high-force manual intervention to overpower mechanical torque and prevent a collision or roadway departure. Chronology of manufacturer notice: - Oct 2024: Initial consumer dispute logs flagged steering safety concerns and unresolved campaign items. - Dec 2024: Opened Corporate Case 24164934, formally alerting consumer affairs to dangerous steering wheel jerking. - Jan 2025: Presented to an authorized dealer; an OTA software update was deployed, but intermittent tracking failures persisted, including failure to recognize lanes at night. - June 2026: Under Case 42680760, the system failed acutely on the interstate, jerking the vehicle out of painted lanes. The malfunction originates in the LKA steering control module and camera hardware, which are intact and available for inspection. Dealerships have not replicated the defect during brief diagnostic windows due to its intermittent nature. The manufacturer has deflected these notifications and refused a forensic diagnostic sweep or mechanical remediation. Instead, case managers attempted to close the file by offering partial financial goodwill for an unrelated cosmetic paint delamination defect on the same vehicle. No warning lamps or error messages precede these events; the system executes aggressive mechanical intervention with zero notice. This system error bypasses driver override thresholds, conflicting with vehicle crash avoidance frameworks. Because the computer fails to log diagnostic trouble codes (DTCs) during these steering drops, the manufacturer exploits this data vacuum to deny structural remediation, creating severe multi-vehicle side-impact and rollover risks.

Just read possible recalls on Hyundai Santa Fe's 2025 and 2026's. Just spent $1727.68 at the Hyundai dealership in Gilbert, AZ to replace the front camera do to the faults showing up on the dash. By reading that article it made aware of what may have occurred had we not taken it in for service. This vehicle is a 2020 Sante Fe. You may want to check into it. Oh, I want a refund.

*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.

May 28, 2025

I was backing out of a parking spot and suddenly the car accelerated backwards into a wall. The floor mat was NOT on the accelerator pedal. Obviously, I might have accidently pressed the gas pedal. But, I strongly believe I did not. For me to be mistaken, all three of the following would have to be true: 1) I would have had to put my foot on the accelerator by mistake, even though I am of sound mind and body, I was not distracted, and I have been driving for decades without having done such a thing. 2) I would have had to continue holding my foot to the gas pedal even as I felt myself racing backwards. 3) Having slammed into the wall, I would have had to be unaware that I had caused the accident. That all three conditions were true seems highly unlikely. (Not impossible. Just unlikely.) I can't imagine stepping on the gas when I meant to step on the brake and then not realizing that I was doing so and then not remembering that I had done so. Cars have computers and computers sometimes have bugs. It seems more likely that a computer glitch caused the crash. And, I suspect that, if it has happened to others, they did not report it because they assume they would not be believed. (When I told a friend of mine what had happened, he told me that, on two separate occasions, he applied the brakes on his Hyundai (a different model) only to have the engine rev up and "fight" his braking. He had to press harder on the brakes to stop his vehicle.) Question: does the onboard computer record all of the car's and computer's activities? (Note: I called the police, who came to document what had happened. I don't believe he filed an official report, but if you need what he recorded, let me know.)

Back up camera glitches. Causes driver assist to take control at times when not necessary. Have has this in for service at least 4 times since purchasing vehicle in 2020. Service states repaired each time bit eventually happens again. This last time is getting more severe cause multiple electrical short in Overhead lights, Panoramic roof failure to close at times and rear hatch sometimes only partially opens. I saw recent recall for 2021 and 2022 Santa fe's, I believe this problem is what is happening with my 2020 Santa fe and the scope of the recall should be expanded.

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.

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.

On May 17th, I had an oil change completed on my 2020 Hyundai Santa Fe at a Hyundai dealership. On May 18th, I was parking my Santa Fe in a parking lot with which I am very familiar. I parked in front of the building, but realized that I had not pulled up far enough to the curb. I went to pull up a couple feet and as I started to put my foot on the gas pedal, I heard the engine roar and take off. I hit the brake, but it didn't stop, and I drove through the window and into the building. I was stunned. I have been driving for 44 years, and I have never had an accident that has been my fault. I was in shock that the car would not stop. I thought there might be a recall regarding this issue, but there wasn't. A friend told me he though he read somewhere that Kia and Hyundai were having acceleration issues. I went online and I was shocked that there are so many reports of sudden unintended acceleration and my Santa Fe was one of those vehicles. I saw one website where over 60 people with Santa Fe's have had similar issues. I was very lucky that I did not injure or kill anyone. Hyundai needs to investigate these instances, before more people are injured or killed. I feel these vehicles need to be recalled immediately. I have contacted Hyundai USA and opened a case file. After the extensive repairs to my vehicle were complete, I took my car to the dealership and instructed them to replace the throttle body assembly. To NHTSA: Please grant Defect Petition DP21-003 and investigate these issues.

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.
