An ABC4 employee drove past the accident Wednesday night and caught it all on his android phone.
The four young adults were just driving down the road when they noticed something was strange with the car.
They stopped, jumped out and moments later, all that was left of the car was a fiery hunk of metal.
Eva Grimmer, a senior Alta High School was driving. "We were driving, and then the check engine light went on and it sounded like a lawn mower," said Grimmer.
Grimmer pulled the Subaru outback over, and everybody got out fast.
Blaze Kotsenburg, a University of Utah student who was also in the car said, "There were flames dripping out of the car and it eventually caught on fire."
Grimmer added, "It just kind of exploded."
They watched in horror as the car they had just been riding in was consumed by flames.
Kotsenburg, reflecting on the narrow escape said, "We just barely jumped out of a burning car."
Utah Highway Patrol Trooper Grant Hyland said "Usually in the summer, cars tend to over heat. That's when we see this sort of thing happen."
