My 2014 V6 Engine Failure at 220 Miles

Hello guys,

So my first post, and it’s kind of interesting. I took delivery of my 2014 Mustang V6 Base, with PP and Recaros. I love the car to death, but with 220 miles on the car, it spun a rod bearing and actually siezed at one point on the highway, causing me to skid. Luckily, the motor unlocked itself, and I was able to drive it both on and off the tow truck, although it did sound like a Diesel. I was following all recommended break-in and, as you should do, was not babying the car like a complete grandma, because an engine needs to see it’s entire operating range (within reason) during the break-in (all of which is approved by the big 3 in our Dyno break-in tests). It simply failed getting on the highway with 1/2 throttle @ 4000rpm.

Good news, is it is getting an entirely new engine and FAST; Ford is doing a good job of making this right. I myself am an Engineer, and oversee test engines and failure investigations for a living at a large automotive supplier who makes parts for the 3.7. So, I do understand the sheer poor luck I had in receiving a bad engine. Sometimes, shi* just happens. However, I need some assurance that other people are also having good luck with their mustangs. I purchased this car to autocross with, and after the break-in period, I would like to have worry free driving and not have to baby this thing forever. I don’t abuse vehicles, but I also didn’t buy a mustang to go to the grocery store with, if you know what I mean.

Any road racers, auto-crossers, or drag racers out there with good luck stories you can pass along?

Haven't spent much time on the track yet, but 15,000 miles and not a single problem to report. I drive it hard.

Very unfortunate what happened with yours, good to hear Ford is making it right. Even if 99.99% of them work perfectly forever, its still a fair number of blown engines waiting to happen. Like you said, it sounds like poor luck. Most of the engines that have let go have done so under poor tuning or extreme circumstances. Good luck with your car

10k and I drive like a stole it. This is the first really bad report I've seen so far. Good thing Ford isn't dicking around. VERY lucky you didn't tune the car already.

Closing in on 18000 miles (in 13 months!) here. I've done a cross country trip, 6 auto-x events and taken it to a drag strip 5 times for some runs. Not a single issue so far.

Since you obviously know a thing or two about engines, this PDF from supersix will probably interest you. It gives a good bit of information on the engine, what its made of, and what it should be capable of. You might find it a little reassuring actually.

Seems a little bit more than odd that you of all people would get an engine that pops so soon.

glad you are reasonable and your dealer is taking car of you. Stuff happens (sux but true) good luck and be reassured yours was the odd ball.

Just a Ford opps, had it happen to my 01 Lightning, engine replaced ran better at the track than the first one. I took my stang to the track with 40 miles on it, waited a couple weeks to start messing with it just in case something wanted to fall off. I figure if it makes it 1000 miles and through it's first oil change we are all good, good luck with it.

Thanks for all the responses guys!

You should have seen the dealer's face when this bright blue mustang they had unloaded late that week from the car carrier was sitting in their service lot that weekend.

The thing that worried me was it happened while accelerating on the cloverleaf entrance to the highway, so I thought I had an oil pump issue and lost pressure during a turn. I will certainly post in here once I get the engine diagnosed though. A guy I work with will likely get the bearings back so I can get an exact idea of what happened.

Please keep bringing on the stories, you are already making me feel better!

Dealer estimates early next week I will have my car back

Check out this member's profile and threads/posts for a pretty good example of what these motors are capable off and what they will take. It would be interesting to know what caused the failure if they perform post mortem.

This is the very first I've read happening to a brand and completely stock 3.7l. Really sorry this happened to you and glad you're safe.

19K Miles and running well. Procharged for 18K of those miles. Both Drag runs and road racing on the motor. I have a oil drip coming from the main seal. So next clutch change I will replace it.


I would be interested to know more about your Job...

That's the first failure of a non-boosted and stock 3.7L I've seen. I've put 8k on my new 2014 since April and am loving every single second of it. I'm thoroughly impressed by this engine and the car as a whole. Rest assured (and I'm sure you know this from your line of work) that you just happened to have bad luck and received a dud from the factory. It does happen unfortunately, but don't let it sour your experience. I wasn't 100% sure about this engine and car before I made the purchase, but I'm absolutely thrilled with it now. Best of luck on the transplant, and I'm really glad to hear Ford is going the extra mile and taking care of you so quickly. Keep us updated on the situation if you can!
