my 3 month old 2021 suburban won’t start. The starter spins the engine but there is no ignition . Sometimes it starts briefly but not long enough to put into gear. The issue happened the 2nd day but not long enough for me to notice. I just received a text message to take it for service within 24 hours. When I got to the dealer, they read the code ans it had basically taken too long to start. But the issue had resolved itself . Now 3 months later the problem has reappeared except it won’t start at all now. When I take my finger off the start button, it continues to act like I am still pressing the button and I have to press it again to get it to stop. I am having it towed this morning, I hope they can find the issue.

Well, apparently there is a service bulletin issued March 5th. The solution is to reload the software to the ECM. If you get this code, don't wait until it gets worse!
