Transmission acts like it is slipping and shifts abnormally in forward and reverse, driver window up/down button doesn't work correctly it only makes the window go up 1/4 of the way so you have to let go and press it again. The radio keeps showing and error message waiting to get into the dealer

About an hour into driving home on the freeway, my car alert system went off and the car automatically began to decelerate and the dashboard display showed instructions to check hybrid charging system and to check surroundings and to pull over when safe and to not drive vehicle. The check engine light, the needs maintenance light and the check oil light all came on. After about 15 secs my vehicle lost all power but did not turn off; the steering wheel became locked. I placed the car into park and restarted it and the warning alert alarm ceased, but now the check engine light stayed on. The steering wheel was movable again and I was able to pull to the shoulder where a California highway patrol officer pulled up and asked me if I was having trouble. After our conversation, I was able to continue the additional 40 mile drive home as the local Hyundai dealerships were closed until the next day, Saturday March 18. I was able to drop my car off in the afternoon but due to their booked schedule, it could not be looked at until Monday March 20th and stayed over night. The technician called me that day and stated that the car test ran on it came back passing and no issues found and that they drove it about 20 miles and no issues and I was able to pick up my car on Tuesday. However, the same system issue happened 3 more times before I was able to take it back into the dealerahip later that week and it has been there as of 4/21/2017. I received a call today that a replacement hybrid battery was installed and after more tests I may get my car back.

When pressing the accelerate pedal there seems to be a delay in response. The delay can be as short as a few milliseconds to almost 3 entire seconds. This problem happens randomly, and makes my wife and I very nervous when trying to maneuver or proceed into traffic after being stopped.
