Hi folks. I've recently bought a civic 2018. Car is in good working condition. But a couple days back, the car started to behave strangely. I usually let it warm up before setting off in mornings. However, one day it just switched off while warming up. I tried to start the car again, but it just showed all the warning lights and the brake pedal blinker but wouldn't crank. After two or three attempts, it cranks up and goes. It's doing this since every morning. It even turned off mid traffic one day and did the same.
I thought it must be the immobilizer issue because it also blinked the key sign, so got the new cells for the remote. But the same issue happened when I tried to start it cold today. Can someone help in identifying this issue.
