Something small but annoying happened after my car died last week, and I am curious if it is just me. My 2017 Honda CR-V would not start one morning, a neighbour helped me with his cables, and the engine finally turned on after a few tries. I was happy, but then I noticed the clock was back to midnight, the radio stations were all gone, and the trip meter had reset too. Even the window buttons felt strange for a day, because the driver window would not go all the way up with one touch until I held the button for a few seconds. That night I felt curious, so I decided to visit Jumpstart Service and read about how a jump start works, mostly to see if this reset is normal. It explained the basics in easy words, but it did not say much about what happens to the settings inside the car. So I want to ask people who have been through this. Is it normal for the clock and radio to reset after the battery goes flat, or does it mean something got damaged? Will the one touch window come back by itself after a few days of driving, or do I need to do some kind of reset? I also heard that some cars forget the engine idle settings, and that the car may run a bit rough for a short time. Is that true? Another thing is the saved code for the radio. A friend said some cars ask for a code after the battery loses power, and if you do not have it, the radio stays locked. Has that happened to anyone here, and where do you find the code? I also wonder if I should change the battery now, since it is about four years old and the car sat outside most of the summer. How do I know if the battery is weak without paying for a full check? Is it normal for a shop to test it for free? If you had the same resets after a jump start, please tell me how long it took for everything to go back to normal, and if you needed any help to fix it. Even a small tip will help me a lot. Thanks for reading, and sorry for the long message.
