At highway speed the computer has attempted to pull the car out of the lane into the adjoining lane as if in attempt to avoid something. This is happened at highway speed's about six times. Vehicle also at one time applied the emergency brake as the vehicle is approaching an intersection as an emergency stop. The car would not move for several seconds. When I brought the vehicle into the Hyundai dealership the representative immediately suggested that there was a rodent problem. This was confirmed not to be the case.as there did not appear to be any other computer messaging the technician suggested that maybe it was the California fastrack responder unit. They suggested it be relocated which I did. The problem lies that you're not sure that this is what caused the problem and the suggestion 'to drive it to see if it repeated' as it does not sound prudent from a safety perspective. The computer pulls at a hard level which makes it difficult to maintain the vehicle in the lane and it suddenly releases the pulling which jerks the car back into the driving lane much like an over correction. This is obviously quite dangerous and I would suggest something else is done to either confirm or disapprove the responder issue as these responders are common and it was placed per the instructions of the fastrack.

Several occasions the safety features of this 2019 Hyundai Santa Fe deactivates. 3+ occasions the vehicles frontal collision avoidance, lane keep assist blind spot detection automatic high beam lights as well as cross traffic alert suddenly will cut off. Have taken vehicle back to dealership where purchased to be told no codes are being stored. Contacted Hyundai usa several times to get a run around or the response if its not recording there is nothing wrong with the car. I have owned a 4 Hyundai Santa Fe's and never had the issues I am having like I am with this one.I do not take my grandkids in this vehicle as im worried that if these safety features fail to work I dont want to chance their lives in a vehicle that could possibly experience more severe issues or worse. Dealing with Hyundai has become a disappointment as the 2004 Santa Fe I own is by far more dependable than this one.

On March 5, this vehicle stopped while driving in the middle of a street. I was unable to start the vehicle and me and my passenger could have been seriously injured or killed. Car was towed to dealership and has 2600 miles on it. I have found that Hyundai is doing a recall to replace starter and a software update. I have been told that because of the new technology this vehicle has which is an automatic start and stop at a stop sign or stop light that the starter shorted out and apparently the software in the car just stops the car while driving.. this happened while driving the car at 35 miles/hour on a busy street. It is a miracle that I was not hit and injured or killed. Car is at the dealership waiting for a new starter and software update with a possible ship date of March 31, 2019. These 2019 Santa Fe are not safe to be selling to the public with this known defect.
