“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. …”

“They have fixed zero recalls. I have no wipers at all. I’ve attempted to get a resolution multiple times with no care or concern nor resolution. This is ridiculous. A recall almost 8 months and people have zero wipers!!! And the engine recall. It’s going to blow up before it’s fixed!”

“The intermediate shaft has gone bad on my 5 year old car. Noticed it on 12/11/25 after owning for 1 year. I’m slowing losing oil which then can cause my engine to go out. I have read many things stating other peoples frustration with this $3.59 part going bad in the 2021 ford explorers but to get it fixed you have to drop the entire engine resulting in it costing $1,800. I think ford should be responsible for this and aware to make a better part.”

“While our 2021 Ford Explorer with 47,000 miles to work the vehicle warning light came on stating the vehicle was overheated and shut down. We allowed the vehicle to cool for 20 minutes as recommended by the owners manual and then restarted the vehicle which immediately overheated again. We had the vehicle towed to the local dealer who diagnosed the issue as coolant in the oil forcing a replacement of the engine and coolant systems.”

“Got it in the car and pushed the push start button. The cars engine turned over only half way and started to restart and turn over multiple times even though the motor was running halfway. This went on for 15 minutes until i opened up the hood and looked down and after a couple minutes the engine seized and turned off and started smoking, shortly after started on fire from the bottom of the engine. The fire went on for 10 minutes until we turned it off.”
