I live in Miami where it is always hot when I bought the car it gave 300 to 325 but lately it only gives 270 or less and I see that the same thing happens to other people I don't know if it was the OTAs or the battery is not reliable
If it's not flaking, maybe someone hit it in the parking lot because I didn't hit anything. If it happened to no one else, it must be something that hit me
