Electrical systems in cars are extremely noisy and can destroy unprotected electronics.

Post a wiring diagram.


In part 1 of your code there is an extra }. Delete the } at the end of that file.
If you are using a NANO or UNO or similar, I suspect that your use of the String class is causing the problem.
Change all uses of the String class to C strings and it should solve the problem.


i'll be more thankful if you send a link about the  C strings or an example
and how does a ram problem destroy the SD card hardware that it become unformattable


What kind of cardreader do you use with the Arduino?

SD cards are 3.3V; using 5V power and signals can damage it after a while.
If you understand an example, use it.
If you don't understand an example, don't use it.
