Power steering loses power and window between speedometer and tach goes blank. Car keeps running but no power steering and cannot take out of park. Must restart the car to solve issue. Happened several times while at idle, in park. Happened once while in drive, at idle while stopped, and was able to drive forward when I discovered no power steering. Concerned it could happen while driving.

The car starts alarming out of nowhere while driving at 70 mph on the interstate and the Hybrid System Warning - Safely Stop and Do Not Drive along with the wrench, battery light and engine light all appearing on the dashboard to pull over and do not drive when this occurred I lost total control of the vehicle. The brake peddle goes all the way to the floor enabling me to stop and I lost the ability to steer the vehicle as the power steering went out as well while this was happening. I almost got killed as I was on the highway driving at 70 mph. I immediately put on my hazards lights to signal to other drivers that I was having mechanical problems. Thank GOD I was able to pull over without anyone hitting me from behind. I have had major major issues with this car since I purchased it the engine seized up on me in the same manner back in 2020 and the engine was replaced. Then there was an issue with the transmission and that was also replaced. Then the brake booster also failed and had to be replaced as well. Hyundai aught to be ashamed of the production of this vehicle as it is truly a severe risk to the lives of the consumers not just the person who is driving this vehicle but also to those who may be behind someone driving as this could cause a major accident and people could be killed. These cars need to be recalled and they need to get down to what is causing these issues in order to fix the problem. I pray that you all make Hyundai do a recall on this vehicle as I have googled and see that there has been many others that have encountered these same issues. I am filing this complaint in hopes of you all getting involved to do something about this. Any help with this will be greatly appreciated.

Had motor replaced from a previous recall, 4days after this fix I noticed a rough idle. Went to numerous shops incld dealership was told by dealership that recall was done and any other repairs would be out of pocket. Problem has progressed from rough idle and engine noise to poor acceleration and mistimed boosts. As in when entering highway car doesnt accelerate very fast very long delay before boost intiates. Once at desired speed when slowing down car boosts without pressure to accelertator!!! Now that winter has arrived, sporadically on cold start car idles even rougher and sounds as if it with shut off. When driving in traffic car idles rough then shuts off!! No power steering! No lights ! No power! This happened whilst car is in drive and in motion! I try to avoid hwys and night time driving when I can as im scared to death of this car. I purchased it used in dec2017 11 days later intial issues began with car loosing power. Now after issue was "fixed" by replacement motor same intermediate lost of power issues again but with the added boosting issue as well now.

Power steering and non-requested activation of traction control_ I was pulling into my carport about 2 months ago when I lost power steering on my car. I called the dealership about 20 miles away and they told me to bring the car in the next day. The next day the power steering worked as normal so I called the dealership back and they suggested to bring the car in if it happened again. I was leaving my doctor's appointment on june 12th and the car had no power steering again. I called the dealership and told them I was nearby and I was on my way to them. I got about 200 feet from the doctor's office when my car started shaking and I couldn't control the steering. Luckily it was a 35 MPH speed zone so I was able to get to the shoulder quickly. I thought the engine died but it was still running. I turned the car off and restarted it to see if the problem fixed itself, but the traction light was on and I still had no power steering. I made my way slowly the 5 or so miles to the shop. My vehicle had 54,358 miles on it when this happened the second time. Out of warranty because it is over 50,000 miles. This sort of issue should not happen on a car with so few miles and I take very good care of my vehicle, oil changes, tire rotation, brake inspections, etc.I had to pay out of pocket for the $1310.00 in repairs to replace the upper part of the steering column where the 'power steering unit' is located. I contacted hyundai USA and they couldn't do anything to help me. I disagree. My car has low miles and this type of danger should prompt a recall and re-imbursement of most, if not all, of my expenses. I commute to work on interstate 5 and if I had been going the 65 MPH speed limit when this happened, I could have been killed and maybe the drivers around me . I am not entirely sure that the problem has been really fixed. I feel uncomfortable driving my own car.
