So put a new starter in and I was still having the same problem of the car starting and then if I tried to immediately restart it wouldn’t. Replaced battery terminals, battery fuse, brake switch, push button switch, no fuses blown and throwing no codes, so took it to Hyundai yesterday to have them put it on diagnostics. What I thought was funny is that I have done all the work and he looked at me like I was stupid because I got help from this forum and doing my research. The Hyundai tech said “they all think their experts” talking about forums. I left and thought what a dick. They called me this morning and told me I needed a new BCM and that it was $1100 plus $200 to flash it. I made sure I asked him the BCM or ECU and he repeatedly told me BCM. What a douche I can buy one new from another Hyundai dealership for $150-$200 and have it flashed for $200 plus 1 1/2 hour labor or I can send it off and have it repaired for $225 and not have to it reflashed and a lifetime warranty at g7computers.com. Why would he think I’m stupid. LOL. Honestly I don’t even know if it is the BCM it could just be a bad ground or something. Because if I let the car sit for a little bit it starts right up and I have been able to get it to restart after shutting it off a couple of times so I think it’s a wire what do you all think and where do I start checking. There are no warning lights on, the only problem is starting and restarting and navigation screen is fading out but the rest of the car is fine?
