Idle stop and go technology feature cannot be disabled. The system turns itself on after I have turned off without warning. After driving a few miles with the feature turned off and stopped at a light, the engine will shut down, thereby turning the technology back on. I have almost been in several accidents thinking my engine was running when it was not. There should be a way to disable this, not just temporarily turn off. I have brought this to the dealer's attention but they are mystified as I am. This has been going on since purchase last summer, though below I am asked for a specific date it happened.

I purchased a brand new 2019 Hyundai Santa Fe on February 20, 2019. On Sunday, February 24 while driving on a back country road going no more than 35 mph, there was a loud noise on the roof of the car. I opened the electric cloth cover and the sunroof was shattered and glass started falling in the car. Contacted the dealer the next day and was told to contact my insurance. The dealer or Hyundai should cover the cost as I only had the car for 4 days.

My new 2019 Hyundai sante fe from the time I bought it had the yellow check engine light come on. It said the bsm system wasn't working. Then the engine would not start on 4 separate occasions. I had to wait to get it to start. There have been 3 occasions when it did start it sounded like it was going die, very sluggish and didn't want to accelerate. The RPM would not increase. It also started 2 separate occasions it lost steering wheel power and the A/C stopped blowing cold air. I had to turn it off and wait to restart it. It is currently at the dealership waiting for the blind spot monitoring modules. The first time they replaced the module it still showed it not working. So now it is undrivable at gene messer Hyundai in lubbock Texas, they say it's not safe to drive so I am driving a loaner. They say they can't determine why the engine did the described things above. These things happened while in motion and parked.

I bought the vehicle August 1 and drove it home, 50 miles, at 75+ mph. Immediately I noticed a high vibration in the ride as well as looking in the rearview mirror the cars behind me were blurry from the vibration until I place a finger on the mirror. I returned to the dealer the next day relating to the vibration. They balanced the front tires. I returned home and the vibration was still there. The vehicle has been at the dealer 4 more times with no solution. I have been supplied with a rental for a few days and was told the SUV was ready. I picked it up on a Saturday and asked for someone to go for a ride to see if the vibration was still there. No one was available so I drove it home and the vibration was still there. I returned it to the dealer and an hyundia engineer took it for a test drive up to 70mph which was in the city and not highway driving. I had a conference call with the GM and was told that the engineer said all of the SUVS vibrated and this one was more "pronounced" which was not in his report to hyundia who I've been in contact. I believe this vibration is not in the wheels, one tire was replaced, but mechanically elsewhere. It has been at the dealership since 9/25/2018. I believe this SUV to be unsafe and that other components will fail. This is my 3rd SUV and I've not had any problems with the first 2. another engineer is scheduled to inspect it 10/23/2018. I am a helicopter Pilot and know what vibrations can do to mechanical and electrical components.
