service light, steering assist problem, traction control

About 7 months ago my car would turn off completely and lock up with the Auto Start. I took it back to the dealership and they stated it was the battery. I replaced the battery. About 1 months ago my car would not want to start in the morning. There would be a clicking noise... all the electrical would turn on in the car. Battery saver was active. About 2 minutes after all the electrical turned on a notification to start the car would come on. I would start the car and all the lights in my picture would pop up then disappear. About a week ago after turning on the car (after waiting for the electrical to come one and the battery still charging) all lights came on and stayed on. I took it to a mechanic on 7/2/24 and the mechanic stated it was the Alternator. on 7/3/2024 the Alternator was replaced but the problem was not fixed. I am lost at the moment and don't know what else to do.

Dealer wouldn't even look at it. It's sad to make an appointment which will take 1 to 3 weeks to get in. You might want to keep it parked if does not operate safely. Really - a warranty means nothing if the dealer is too busy to even look at the car and it is just sitting unfixed in your garage. I HAVE to keep an old Ford around to have transportation. This is the second electrical problem this vehicle has been "parked" for, now 3 weeks so far.
