I have Ford F150 Ecoboost. The one where the engine cuts off at red lights ya know. Last Thursday night I had a Charging Service System Now pop up on my dash twice on my way home. I called them Friday morning to bring it in. I was told Monday would be the earliest I could get in. Also told them after watching a utube video it might be the alternator. I was told we've seen this before its probably just a sensor. Friday night I tested to see how it was doing and it was completely dead. Called Saturday morning to have it towed and got road side assistance. Waited till Monday to see what was wrong and they said loose connection we fixed it all is good. Come get it. On my way home same indication popped up. Went right back and got a loaner. So now on Wednesday they confirmed it was the alternator and replaced it, came and got it, was not told sorry for all the inconvenience was told to fill gas tank on loaner and that was that. I'm sorry but if costomer satisfaction is number one you failed. I will not return. Why should I fill your gas. You owe me the time you wasted and the gas you used up in my car testing it to see if this time you actually fixed it. Also my truck is a 2018 with 10500 miles so it was under warranty.
