This complaint has to do with the aeb ( automatic emergency braking ) system. This was a feature that led me to purchase the car and I discussed it with the salesman at length at the time I purchased it. Shortly after purchasing the car, I started trying to test it to see if and how it worked. I could get no indication it was working without wrecking it. There is supposed to be 3 warning stages according to the manual ( 1 a message on lcd with warning alarms, 2 a 2nd collision warning message and limited control of the brakes, 3 emergency braking ). I never saw any of these. I took it back to the dealer along with a video in which I tested it running over party balloons. They said it was working as designed. I wrote Hyundai America and they suggested I take to another dealer which I did and they said the same thing. No one cares or is interested in seeing that the system works. I have attached a couple of still photos I took from my video showing just before and after the collision with the balloons. I have several videos, I could send if interested. Thank you

9/18/17 while driving on highway at 65 mph the ABS light came on and the vehicle while trying to accelerate moved slow as if to not want to shift. I got to the side of the freeway and turned the vehicle off and when I re started a few minuets later the light went out and vehicle operated without out problem. I made appointment with dealership for 9/26/17. They did some recall items and I mentioned the problem and was told if the light is out it may not show up. The failed to not on service order this issue. On 10/24/17 while driving on freeway and had traveled about 50 miles from home the ABS light came on again and this time it notified me on the radio screen to contact blue link as there was a possible condition with the brake system. I contacted blue link and they made an appointment for 10/27/17 at 8 am at the dealership. After 6 hours waiting on Hyundai tech support to get back with them to run diagnostics. Last 3 months vehicle monthly report on vehicle shows a problem with the ABS system. They claim they are unaware of any issues.10/24/17

Smart cruise control fails to brake intermittently. It is designed to match speed with the car in front of it. It usually works fine, unless another vehicle cuts in front, even if there is enough time to brake. I have to slam on the brakes manually to avoid an accident. This has happened on multiple occasions. I now fear using the cruise control at all, as it does not perform correctly 100% of the time. The dealer said they could find nothing wrong, but this is a very real issue that puts my family at risk. They have now called in a master tech from Hyundai to look at it, but I wanted to document this issue. I noticed it first within two weeks of purchase. Hyundai support closed my case several times without action. I bought it 5 months ago. Current mileage is 3462, so it is well within warranty.

While driving at 25 mph, numerous warning lights illuminated, including low tires, steering, other codes consisting of letters. Power steering failed, power brakes failed. Engine was still running. We were able to pull the car off the road safely. Steering warning light still illuminated as were tire warnings. The tires were fully inflated, engine still running. We turned the engine off, raised the hood to check for thrown belt. Belts were intact. Tried to restart the engine, it made a clicking and a sizzling sound and would not start. Called dealer, dealer gave number for Hyundai assurance. They came and picked up the car. If we had been driving any faster, or in traffic, the automobile's failure could have caused an accident. If we had been on the highway, someone could have been hurt or killed. After a couple of days we were given a courtesy car. After a week, the car was repaired. The problem was reported as a fuse on the positive battery cable. Cable and battery were replaced. Vehicle was in motion on a city street at time of failure.

On April 15, our brand new Santa Fe was involved in an accident. While driving in low speed traffic suddenly, while my fiance rear ended someone. To this day she cannot figure out what happened. She is a careful driver, does not speed and knows that the area were she was driving is high traffic and was coming up to a red light. Both of her hands were on the wheel and she wasn't on a phone or anything. She believes she hit the breaks, and as stated before still does not know what happened. After reading these complaints we are wondering if we had the same issue as someone else who reported and is the cause of the accident. We figured we would report this. We are also wondering if other people are having similar accidents since there has been a major issue getting parts to repair said car (car has now been off the road for 11 weeks most parts required for repair have been externally backordered and Hyundai has been extremely unhelpful to help us get our car repaired). The consumer stated the vehicle lunged forward, while slowly depressing the breaks. The manufacturer was notified. Updated 11/2/2017
