2.7L blown engine failure list . . 68 so far [Updated: December 13, 2022]

[1975U15]

Well, you might need to add me to the list. Still waiting for the dealer to look at it. Today I was driving, maybe 30 mph when all of a sudden I thought I heard some clicking noises from the engine, power drops and was barely able to pull over, then engine dead. Only warning lights I got were a forward sensor failure and then a message telling me to pull over put it in park and restart. Was not able to restart, starter fires but doesn't seem to engage with anything. Based on some quick reading of engine failures I have similar symptoms but no smoke from engine or exhaust. Hoping for the best but preparing for the worst. Unfortunately did not get any engine build info but will see if I can from the dealer depending on what they find.

~2500 miles on the car, built in October.

Sorry to hear. Who's your dealer here in Utah?

The replacement engine was faulty as well. Still in the shop awaiting its 3rd engine.

wow....did you take delivery of engine #2?

Looks like 4 reported in last hour to me, with @Jaycefox having two.

Bought my bronco on Nov 6, 2021. Engine blew at 1,166 miles on Dec 11, 2021. The replacement engine was faulty as well. Still in the shop awaiting its 3rd engine. Not sure the build date.

It could be a faulty install by the dealer in this case. If the oil lines or turbos had debris and were not properly cleaned out, could of trashed the new engine. Not saying that is exctly what happened but it is a possibility.

To the new guys, be sure to file a report with the NHTSA. Very easy to do and it records these issues.

I did not. They installed and road tested at the dealership and determined it was faulty.

Crandall (now Karl Malone) Ford in Park City. They've been great to work with but they are a smaller dealer and I imagine this is their first Bronco tow job.

Why can’t ford make a statement this is getting ridiculous. They have to know what group of engines is bad

I agree...we have had a few reports of replacement failures, however they appear to be "DOA" type situations. I don't think that we should treat an engine that never ran properly, for whatever reason, from the time it was installed, the same as the type of failure we are trying to track. They are worth noting, but clearly not the same pattern of failure that we are gathering data on here.

My day 319 hit 2000 miles today. Passed a Porsche at about 80 mph. So there’s that.

I really hope both of my orders with the V6 come intact. I do not want to order the mailman's 4 cylinder Bronco. Just reminds me of air-cooled 4 cylinder Jeeps, which they claimed had adequate power. Now days with freeway driving at elevation and 35-37 inch tires we really need a V8 but we have to settle for 2.7

What Jeeps were air cooled? Besides the m422 mighty mite series? I don’t know of any others.

I’ve updated every now and then to offer encouragement. My Julian date is 21228 and my mileage is 8200k.

So anyone keeping track, wanted to note what I found about my October build today. My blend date was Oct 18 and my top has a build date sticker of Oct 21, the day before I got my built email. I’ve been loosly following along with this 2.7 saga, assuming I was out of the hot zone.

I looked at my engine sticker today and I am 21224. August 12, and the same day as three known failures tracked here. Surprised my engine was built over two months before Bronco was assembled.

Scary looking pattern. Almost looks like Round 1 was the initial bad batch before any problems were known. Plant shut down and they "fix" the issue.

Round 2 is a mix of good and bad parts testing new valves while still using the old ones (or using up heads with bad valves). This could literally narrow down to which line on that day your engine was built and when those heads were built. July 28th and August 12th were bad days. I'm hoping July 30th ran heads with new valves.

My JD is 21196 with blend of 9/7 so almost two months between engine build and blend.
