Scroll down to the bottom. It’s under complaints. The letters are in attached documents.

NHTSA has quite a large website. Where do I begin? Is there a link? I searched “complaints” but can’t seem to find it.

Just got back from a week long road trip to Off-Roadeo and beyond. I just said F it in some of the most remote driving our country has to offer. Over big mountains, below sea level in Death Valley, 100+ degree driving outside of Vegas and the majority of it at 80 mph+. 40+ hrs. behind the wheel and over 2k miles. I'm at 7445 miles now on a 21214 with three engines blown on that build day (one of which is 4 engines in front of mine in sequence, one 15 after). Sell it or use it I say. Could happen at any time I guess but only one way to find out (crossing fingers and knocks on wood).

I’m also a 21214 and have been nervous but adopted your same attitude. Just got back from a 1500 mile road trip through central Oregon. No problems. Hit 5,000 miles.

Looks like this list isn't expanding at all. That's good news, maybe they worked thru the bad batch :)

in Ford Service Technicians Forum there are multiple reports of broken valves at the keeper groove
- in the failed engine replacements, many times they don't perform a full diagnostic but sometimes they look into it
valve stem w keeper groove.jpg

The exploded view reminds me of the cap I put on top of my 1970 VW beetle engine valve stems because the top of the valve stems were worn out. @Lucchese does part 6571 click into the keeper groove or is it to provide standoff between the spring and stem? Or would it be part 6514 that engages that groove. what is part 6571? If the valve is failing at the keeper groove, then it would be the stem that was not properly heat treated or made of the wrong steel alloy. I used to work in the O&G industry, and I recall a well that was completed in the 90's with 5-1/2" casing that was made in China. I can't recall the casing grade, but typically the best pipe has a minimum yield stress between 80kpsi to 110kpsi for use in the industry. This pipe had a catastrophic failure under pressure. The failure point exhibited brittle failure. (45 degree angle sheer failure). It appears the casing was out of spec with regard to hardness. It was too hard. It was possible some lug head thought exceeding the hardness spec was OK, and the pipe was shipped and sold. Is it possible this is what happen at LEP? Is it possible that a valve stem that exceeds the minimum yield strength may have looked good to an inexperienced tech, so they passed the valves without considering the hardness spec? I am certain this sort of failure happens in all industries, and in some cases the mistakes are recognized, but someone makes the decision to let it go and hope for the best. Sometimes they get away with their exceedingly poor decisions, and sometimes they don't. In the end, those who decide to let it go and hope for the best have no place in organizations where not doing their jobs will result in property damage, injury or death. I can't know if there are any managers in FoMoCo who make exceedingly poor decisions and minimize risks because they have gotten away with their bad decisions in the past. But I will mention just one case where managers made the wrong decision because they thought they could ignore the engineers who told them the conditions were out of spec.

blown engine reported - 'Bronco 6th Gen' @FB
- Bill Thorpe - January 6, ~ 2700 mi

maybe Mr. Thorpe will share the engine ser#, or last-8 digits of VIN
- we hope to include the engine build-date in B6g tracking



Blown Engines List - Updates
- w recent new info it appears lines 13) and 15) were prob same person
- i.e. fbf of bytheway, and charr124@BN
- not 100% sure, but prob same I believe

I wouldn’t say I’ve panicked, but it was definitly nerve wracking being stranded on the side of a freeway with my dogs in between a guard rail and 18 wheelers for 90 minutes in 25 degree weather.

It’s all relative, but that was a big deal to me. That negative feeling has only been compounded by Ford’s unwillingness to shoulder the tow cost or even offer a courtesy car for the month+ it’s been out of comission since.

I only owned the car for 8 days when it died. Super frustrating. But yeah, I’m not panicked, I’m irritated.

I’d also advise those with Julian dates in the danger zone to drive the shit out of their Broncos and get the replacement over with if one is needed. That 3 year / 36,000 mile warranty doesn’t last forever.
You should be able to get a 100k powertrain warranty out of this. I did. It's worth asking for.
