Hello, I have a 2018 Civic with 70,000 miles. In August I went to start the car and it wouldn’t start. Ended up getting a jump and drove it to the nearest mechanic. They misdiagnosed the car by saying it needed an alternator replacement when really all it needed was a new battery. I took it to the dealership immediately after where they replaced the battery (also tested the alternator and determined it was good). After driving the car the check charging light came on. I called the dealership and my car has been in and out with them since August. They can not figure out what exactly is wrong. They finally determined it was the battery sensor and replaced it. Once I started driving it, the message came back on so that’s not the issue. Anyone else experienced the mechanics at the dealership not being able to determine the issue?
