Car made incredibly loud sound when I dropped off my kids at school. But hasn't made that sound since?

Yesterday morning I drove the kids to school and I was waving at the teachers waiting in the lot an incredibly loud sound that sounding like a firework and smashing metal happened in the front of the car and my car turned off. Kids went running inside and were crying scared. I called my husband to check it he is a mechanic and he said there's nothing wrong with it. It just backfired. I drive a 2018 Ford Fusion. I didn't know that they would backfire this early. What should I do? What do you think it was?

Still under warranty, take it to the dealership.

Ran over a lunchbox popping a plastic bag.

Go to the repair shop and check it out.

If you are sure it was your car and not someone next to you, what a logical and intelligent person who knows very little about cars would do is take it to the dealer to be looked at. That's what having a warranty is for.

Still not listening to your husband I see.
If you don't trust your husband go to the dealer. It's a 2018 and has a warranty!

You DO sound like a troll.
What should you do?
Write fiction full-time and get paid for it.

  • Trump is a Racist, but hasn't everyone forgot Romney, McCain, Bush, Dole, Bush, Reagan, Ford, Nixon, Goldwater and Ike? Well actually hasn't the race-bating started to intensified since Reagan? How quickly we forget every 4 years and the chants and the driving narrative of the Left? @Grundoon, You're making the same old defense that is part of the prevailing narrative made by the Media and Hollywood themselves. @ xg6 , Actually it began in the late 1970's, until 1965 Democrats had nothing to stand on and there was no Jessie Jackson or Al Sharptons.
  • I'm in high school and about to get my first car looking for a loud, fast and good looking car So far I have looked into ford mustangs, I have a choice between a 2007 ford mustang gt with a 8 cylinder motor with automatic transmission, or I can get a 2013 mustang v6. My question is which of the two cars is a faster and louder car cause I would like to show it off and have heads turn by its engine as I drive off on the street. Thank you very much about to get my first car looking for a loud, fast and good looking car?
  • I dropped something into my car's coolant reservoir? I have a 2008 ford mustang. Yesterday there was a coolant level low light on, so I went to my nearest dealership and picked up a gallon of coolant. While pouring the coolant into the reservoir, a piece of foil (the foil seal you break when you buy it) about the size of a quarter fell into my reservoir. After an hour of trying to fish it out and find it, I gave up. Today I tried again but the piece of foil was not there anymore. What should I do?
  • Looking to buy a car privately which hasn't been serviced in 4 years but only 9000km (they bought the car brand new)? As above. the car is a Ford EcoSport 1.5 titanium it has 9000km only but they say they've never had it serviced? should I stay away from this car? also, since there's no service history could this be a case of odometer roll back fraud?
