The steering wheeled locked up and the dash showed error messages of check hybrid system and refill inverter coolant and car seemed to go into limp mode as I could barely accelerate forcing me to pull over. The messages and issue would go away upon turning off car and turning it back on, however the issue would eventually happen again. This has happened while driving on the highway and other various road situations without warning and making the vehicle very unsafe. I have taken my vehicle to Hyundai Ourisman in Bowie, Maryland (the dealership where I purchased the vehicle) three times over two years and they have failed to fix the problem. They have even replaced the battery in the car.

Driving along, merging onto Interstate, various warnings such as check lane keeping assist, and warnings to stop vehicle and check brake systems. Driving approximately 50mph, the warning started to flash and speedometer dropped to zero then went back to full speed. Automatic braking was attempting to slow the car. Attached photo shows an indicated speed of 0mph, however was travelling approximately 50mph at this time. I also have video of the errors occurring, but there is not a way to upload video.

I was driving on a road approaching a right turn to enter into my neighborhood that has a 3 way intersection where only cars exiting the neighborhood have a stop sign. I turned my right turn signal on as I began to slow down and approach the turn (without stopping as there is no stop sign for my path). As I was about 1/4 way into the turn, an alert for either lane keep assist or driver assistance warning appeared and the steering wheel suddenly could not turn and I was forced to drive straight. Luckily, there was no car waiting at the stop sign or I would have hit them. I hit the brakes and was on the wrong side of the road pointed towards the curb. I saw multiple error messages for lane keep assist and drivers assisted warning but could still not turn the wheel. I slowly drove the car forward, wrestling the wheel to turn enough so I could park on the wrong side of the road. I tried putting the car in park and then drive again but it did not help. I turned the car off and on and the errors cleared and I could turn the wheels again. I then proceeded to slowly start driving home and less than 1/4 mile later as I was rounding a gentle curve (I did not use any turn signals), the same error occurred and I suddenly could not turn the wheel so I slammed the brakes and stopped in the middle of the road. I again turned the car off and on to reset and proceeded to drive the remaining 1/4 mile home and park in my driveway. I immediately contacted the Hyundai dealer and was recommended to have the car towed to the local dealer as it was unsafe to drive. Upon towing the car to the closest dealer, I was able to back the car off the tow truck and park it. While parking, the steering locked up again and I took the attached pictures of the error messages and showed the technician. The dealers in the area all indicated they were so backed up they could not diagnose the car immediately. I called Hyundai to open a case. It has been 2 weeks and they still have not diagnosed the car.

During the accident, the airbag in the steering wheel, barely deployed and threw sparks in the air. Passenger door airbag ruptured. I have pictures of the torn airbag. The cab of the vehicle filled with smoke and sparks came out around the steering wheel. Driver felt like their pants are on fire. To the best of my knowledge, there has been no inspection of the airbag system.

My passenger's front door side vent window glass shattered unexplainably while I was making a left hand turn at 15 mph. This occurred at 7:25am in the morning after pulling my car out of my garage and driving about 1/3 mile before the unexplained glass explosion/shattering. The sound made was a loud bang/pop. Air temperature was around 68 degrees, no air conditioning was being used at the time. No other cars or pedestrians were around when it occurred. I inspected the glass and it does not appear as if there was any possibility it was caused by a rock or a projectile such as a bullet or bb gun. As mentioned the component that failed was a fixed vent window that does not open. Fortunately no passengers were in the car when the glass shattered. It has not been inspected since insurance will not cover the cost of the glass replacement. (Safelite glass to replace for $346.00 (my insurance deductible exceeds that amount). No warning signs before it occurred. (Possible manufacturing defect -impurities in glass? I don't think it was body flex or vibration which may have caused the explosion as I was driving only 15mph. I don't believe it is attributable to thermal stress either -due to no variation between internal and external air temperature)
