I've been lurking on this forum a while, but finally joined to share my experience. Last month out of the blue, my 2021 Ford Explorer ST with 15,500 miles would not start. Attempts to jump it were futile.
I then had it towed in to the local Ford dealer. At first, they were thinking the starter. A few days later, I got a call saying they could not hand crank the motor as it seized up. In addition to that, they found pieces of metal from the piston in the oil pan. The dealer took apart the intake manifold and found that the valve keeper failed thus dropping the intake valve into the #5 cylinder.
This necessitated replacement of the engine, both turbos and even the flywheel and torque converter. Ford covered this with zero cost to me. I was also given a loaner, but I was without my Explorer for a month. Shoutout to Jerry's Ford in Leesburg, VA for doing a very good and thorough job on my truck.
This is a known issue with the 2021 Broncos and is even being investigated by the NHTSA. Though frustrating, this did in the end work out. I just wanted to bring awareness that this can happen to the 2021 Explorer with the 3.0 Ecoboost as it was built in the same factory as the Bronco 2.7 and is a similar engine.
