For the duration of the vehicle's ownership, it has underperformed and operated unpredictably under hard braking, specifically with relation to the vehicle's ABS system. The conditions have caused meto never drive the car in snow, as this weather condition in particular exacerbates the braking issues and makes the car unsafe. Issues with the braking/ABS include: The ABS activating at slow speeds in all conditions, even on dry roads The ABS activating and preventing the vehicle from being emergency stopped in adverse conditions The ABS activating and exponentially extending the braking distance until it disnegages The ABS, once activated, does not stop unless the brake pedal is lifted from its initial activation position The vehicle doesn't appear to have any mechancial braking issues. Everything seems to be related to the ABS system, wheel-speed sensors and/or vehicle-management systems. The overall braking experience in this vehicle with the ABS on is that it simply will not stop within a safe braking distance window. The only way to stop this vehicle is without ABS. There is no other way to safely stop this vehicle with ABS. I have reached out to my Hyundai dealer and Hyndai corporate directly, both times being dismissed without anyone attempting to recreate the braking issues. I have a life's worth of experience driving in snow and multiple ABS activations in a range of vehicles. This is abnormal based on all of the experiential knowledge I possess, as well as a lifelong interest in cars. While I am not an engineer, I possess enough firsthand and academic vehicle experience to recognize the abnormality of this vehicle braking operation.

My vehicle applies the brakes while driving on busy roads when nothing is in my path. I've almost been rear ended a few times because of it and Hyundai has no resolution. Then also my vehicle has lane assist and the computer fought me steering the wheel while driving down the highway. Hyundai replaced steering components in the vehicle but don't know why it happened so they never diagnosed the problem. We have tried to go to Hyundai about the issue but basically they only care about our money we pay and not our safety.

I had rented a Hyundai sante fe in September 2019. I had the vehicle for a few weeks with no issues until I drove over the mountains. I had pulled into a parking lot and was looking to park, coasting through the parking lot, I then backed up and found a parking spot. I was turning right in at a very slow speed, a virtual crawl into a parking space when I pressed the brakes to stop the vehicle when it suddenly revs its engine and began accelerating out of control jumping over the front parking curb and slamming into a chain link fence. The brake was depressed to the floor and would not stop, I pumped the brakes to stop and when it would not stop, I quick slammed the vehicle into the park position to prevent the vehicle from hitting a tracker and causing further damage or injury. I contacted my insurance agent and then I contacted enterprise rental company in bend Oregon. I was on hold for roughly 30 min. I explained the situation and they stated that there were no recalls they knew of and they advised me to contact their tow company and have it towed to the airport in redmond Oregon to switch out the vehicles. I researched on my own and found that their was a similar incident in las vegas, nv reported in January 31st, 2018. This incident needs to be looked into before someone is seriously injured. The isg may be a contributing factor in this case.
