Daughters' 2018 EcoBoost Mustang with under 30.000 miles dead this morning. I put the Battery Charger on it and it showed full battery charge. Took off the charger a few minutes later and started right up. So she drives it to work, parks it, comes out for lunch and dead again. Luckily she has free towing with her insurance so towing company picks it up on a slide back and brings it to the Ford dealership. To make matters worse, and this is the real irk part, they say they can't look at it until sometime next week. Geez.
