Hello all! My car was perfectly fine when I was driving off. When I came home to park it suddenly almost all digital screens turned off except some signs. My electronical hand brake wasn't working as well and the display had an error saying your handbrake is not working service now. My steering wheel also stiffened and interior lightings were not working after that happened. I waited some time and screens came back. After 5 seconds it was gone again. It was like that for a few times than my handbrake started working but the steering wheel was still stiff. After handbrake didn't break again but screen showed service now error. After a day I tried to have a test run for 10 minutes and there were no issues and the service now error was gone. When I park all of a sudden I felt the steering wheel was stiff again but everything else was fine. What seems to be the problem? Sorry for the long post I wanted to make my issue clear! Thanks for any help! I also didnt have any trouble starting the car.

Start by checking the voltage of the car battery. Measure it about 1 hour after parking, if it is less than 12.4V then put the battery on charge for a minimum of 12 hours.

If the car has the original factory fitted battery then it is probably due replacement.
