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.
2019 Hyundai Santa Fe driver assistance complaints
Page 2 of 2: complaints 11 to 17 of 17, newest first, as owners wrote them.
The contact owns a 2019 Hyundai Santa Fe. The contact stated that the check Forward Collision Avoidance warning light was illuminated. While driving at various speeds, the vehicle veered into oncoming traffic. The vehicle was taken to the local dealer where it was diagnosed that the sensor in the windshield had malfunctioned. The vehicle was not repaired. The vehicle was taken to an independent mechanic who stated the windshield sensors were working as designed. The manufacturer was notified of the failure and referred the contact to the local dealer for assistance. The failure mileage was approximately 69,550.
12/26/2021 Driving on I40 E between Santa Rosa and Tucumcari using adaptive cruise control (SCC) at approx 68 m.p.h the brakes were harshly applied which resulted in the vehicle rapidly de-accelerating from approximately 68 m.p.h to approximately 5 m.p.h. (There was a warning displayed on the odometer panel). no vehicle or other obstacle within eyesight to the front, side of rear of our vehicle. Vehicle resumed driving on cruise. No warning prior to the event. Vehicle was taken to the local Hyundai dealership on 12/30/2021 for diagnosis, the mileage was 21066. The technician reported no DTC's found and suggested it might have been caused by the windshield mounted "dash cam", the "dashcam" was not in a position where it could possibly interfere with the vehicle camera, (it has been in the same position since vehicle purchase and remains in the same position today), possibly some critter that ran out in front of us and we did not notice it or maybe a big bug flew into the vehicle. also there was no obstruction to the forward vehicle radar. The vehicle was not road tested. This fault since the first instance has not happened again. this fault has been noted by other owners on various Hyundai owners blogs. This vehicle has FCA + Pedestrian, SCC, LKA.
"FCA" system disabled radar blocked" error came on while test driving on 3 separate occasions but no diagnostic code recorded, prior to taking possession they replaced a camera they thought to be the cause 11 days later during a snowy morning I got the same error again. Again it didn't register a code and I was told by the dealership no code, no problem. Spoke with Hyundai customer relations and was told I have to take it back to the dealership for them to diagnose it, and the condition has to be reproduced for them to note the error but We have not had snow since that morning therefore the system error has not reappeared. The likelihood of being able to reproduce the circumstance during business hours and be able to get it to them to witness the situation is minuscule at best. If this safety feature is deactivated when something as simple as a snowflake blocks the sensor then it isn't really a safety feature. The safety features contributed to my decision to purchase this vehicle (Nov 1st) but all I am told was the radar was blocked and therefore caused the deactivation, but again how can something as simple as a snowflake cause this error and the manufacturer not address this as a safety concern.
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.
