2022 HYUNDAI SANTA FE Forward Collision Avoidance Problems

Vehicle purchased 9/1/24 from Courtesy Hyundai of Tampa. Dealership failed to file registration/tags until 10/4/24. 7/12/25: Vehicle experienced involuntary acceleration and braking, resulting in impact with my mother’s home. 7/16/25: Dealer issued written report stating vehicle was operating normally and documented a recall-related display/audio/camera software update. 8/14/25: Hyundai engineering inspection performed without my knowledge. No report has ever been released. 8/27/25: Hyundai issued corporate denial, blaming driver error and stating braking/acceleration systems were normal. 12/5/25: Second involuntary braking incident at highway speed on I-275. Five uncommanded braking events over ~20 miles. Service Manager stated failure was due to sensor/camera malfunction and instructed that the vehicle should not be driven and to tow immediately. Despite this, the vehicle had been released into roadway operation. VIN lookup shows an open, unrepaired federal recall (24V879000 / Recall 271) for the rearview camera system, marked Recall Incomplete, despite the dealer’s documentation that recall-related camera/software work was completed on 7/16/25. BBB Auto Line denied my claim only because the vehicle was outside Florida Lemon Law eligibility. No safety determination was made. Hyundai released no engineering, sensor, or camera data despite an engineering inspection. This vehicle has experienced repeated involuntary braking and acceleration at highway speed, involving braking, camera, and automatic emergency braking systems, creating a serious risk of loss of control, collision, injury, or death. Despite repeated failures, contradictory diagnostics, withheld engineering data, and an open federal recall, the vehicle was released back into public roadway operation. I request that NHTSA formally investigate this safety defect.

The vehicle has activated it emergency breaking feature several times now on the last couple of months witouth any reason to do so. Presenting a major risk for the occupants and to other vehicles on the roads.

Vehicle began to display Front collision avoidance system error/ radar blocked. This also disabled the 'smart' cruise control features. This happened any time the cruise control was engaged and we encountered traffic. The unit was in the dealer's service department for a week, and the front radar module was replaced and reprogrammed under warranty.

I was driving at approximately 65 MPH using the advanced cruise control system. Randomly, the system disengaged and I started getting 2 MIL warnings on my console. MIL warning 1) was "Check Forward Safety System" and 2) warning the advanced cruise control parameters are not met due to warning 1. A few minutes later, I received a message on my Hyundai Blue Link app showing DTC C162078. After researching this DTC, I found that there are hundreds, if not thousands, of other drivers that experienced this same/similar situation -- unexpected loss of advanced safety features and smart cruise control features. In fact, Hyundai published a technical bulletin for another model with the same issue. The loss of these functions places an unexpected safety risk to the driver if this issue occurs when there is other traffic present. My vehicle was involved in a frontal accident once about 1.5 years ago and this issue has never occurred. This is the first instance of this issue since I purchased the vehicle brand new from the dealer.

Front radar system continues to not work without having damaged caused. Makes cruise control not work. Forward collision not work, etc.

While driving I could not accelerate over 35 mph on the freeway this has happened at 10 times now. While driving my parking brake will come on causing me to stop immediately. This is a huge safety risk not only to me but the people in my car or driving around me. My vehicle has been brought to dealerships multiple times and nothing has been done they can’t find the problem.

automatic parking brake does not engage. Brake is totally not functional

Phantom emergency braking occurred on two separate occasions a few months apart while traveling at 50-60 MPH for no reason. Almost rear ended. Flashing red zigzag alert stating “Emergency Braking”. Vehicle towed to dealership for inspection and diagnostics. Afraid to drive on freeway or highway. Dealership unable to reproduce or solve issue first time. Now at another dealership for inspection.

On several occasions now The vehicle is engaging the automatic emergency braking system for no reason. Several times I have been driving on the highway without a car in front of me and it engages the automatic emergency braking system. This has caused me to almost be rear-ended because my vehicle slammed on the brakes. I have almost been in several accidents now due to the automatic emergency braking activating for no reason and cars almost hitting me.

On three separate occasions over 18 months, the car has entered into front collision avoidance mode by unexpectedly swerving the vehicle and braking. Twice I was on the tollway doing 70 mph on a 4 lane expressway and I drove in between two tractor/trailer semis. When I reached mid point, the car braked heavy on it's own and swerved first the right, then to left. In each incident, not only did it scare the hell out of me, I thanked god I avoided a major accident from crashing into the trucks and or being hit from behind. In the third incident (date of this complaint) I was driving over train tracks on two lane road at about 35-40 mph, there were yellow black traffic barriers dividing the narrow roadway at the tracks and the car suddenly braked and swerved, nearly getting me rear ended and putting me down into the culvert around the tracks. In each incident it was difficult to take control of the car back from the collision avoidance.

First the check engine light was on and the vehicle was vibrating really bad and making a loud sound. Took it to the Hyundai dealership which claimed to repair the issue. While on my home from the dealership ( Hyundai of Slidell), which was almost hours away, the vehicle lost power while driving. Later, multiple lights were illuminated on the dashboard including the epb, auto hold, forward collision, blind spot, check engine, and oil light. The vehicle is currently back at the dealership. Hyundai has been notified numerous times about the issue. This is a safety issue that needs to be resolved. Although there are no current recalls for this issue everything Im experiencing with my vehicle are the same issues reported in previous recalls.

The contact owns a 2022 Hyundai Santa Fe. The contact stated while driving at various speeds, the vehicle experienced phantom braking with the Emergency Braking message displayed. Additionally, the vehicle lost motive power while driving. The manufacturer was made aware of the failure and had the vehicle towed to the dealer; however, no failure was found. The vehicle was not repaired. The failure mileage was approximately 38,955.

Mileage: 38,955

Hi Team, Issue 1: unexpected Acceleration: Recently I found that is there is unexpected additional acceleration when I press gas pedal initially after changing gears from P to D. I am setting up an appointment with dealer to report and investigate this issue. My Car has only around 13000 miles on it. This issue was initially observed when one morning when i headed somewhere there is unexpected acceleration when I slightly press gas pedal. Issue 2: The Advanced Driver Assistance Systems (ADAS) doesn't work properly when set to adaptive cruise control. It doesn't slow down /stop when getting close to cars parked at signal specially as slight curvy roads.
