Hi my name is***** to JustAnswer!

So the service brake, erratic door locks, and stalling at times. All when the truck is warmed up. Sounds like we need to get trouble codes pulled and get a better idea of what is going on. Are you able to take the truck to a local auto parts store? Usually they have a scanner and will check the codes for free. In the meantime I will continue to do research on any known issues. If you have any other information about the symptoms please don't hesitate. Any information helps.
