Hope a new battery fixes that for ya!Never have had full confidence in the battery in my 2018 F-150. 5-7 times in 2.5 years the display on the radio hasn't come on right after a start but will come on in several minutes. When this is happening the fan speed can not be increased. This truck sat for 5 months before I was the first person to test drive it.
I pull mine up to the garage and use a 2 amp old BMW charger, that charges it at 2 amp initially for 15 minutes or so then drops to about 3/4 amp for several hours and then goes into float mode. I try to do this once a month during winter and then again during heavy use A/C season. After charging the vehicle feels better. Om
