I bought my 2012 Platinum from CarMax a few years ago with around 33,000 miles. The truck was in absolutely pristine condition and in the colors I wanted (black exterior with brown interior). I purchased the MaxCare warranty.

Since I bought the truck used, I had all fluids changed (including transfer case, differentials, etc.) along with new plugs, etc. Basicall all consumables.

Since I bought the warranty I can't do any powertrain mods, but I did install a leveling kit, new hangers on the rear, Raptor wheels, and a bed cover. Once the warranty is over I'll do more.

Ever since I've owned the truck it has burned about a quart of oil between oil changes. This is the first vehicle that I've owned that burned oil, but I was told by two different dealers that it isn't unusual for the 5.0 engines. Hmm.

The only issue I've had with the truck is that, just a couple of weeks after purchasing it, the sunroof got off track. That was repaired under my extended warranty. Without the warranty I would have been out of pocket $1700.

Recently the truck developed a misfire. The dealership pulled the codes and the issue was with the #4 and #8 cylinders. I was on a road trip at the time, so the dealer cleaned the plugs for me and sent me on my way (no charge). 800 miles later the problem came back. I was home, so I took the truck to my local dealership.

They called a couple of days later and said that there was cylinder scoring and that I needed a new engine. MaxCare initially denied coverage saying that I haven't maintained the truck, but I had the dealership submit the truck's CarFax which lists everytime I've had it serviced. MaxCare then approved the new engine. The dealership told me that the new engine is $5k, requires 24 hours, shop supplies, etc. and would have cost me almost $15k out of pocket without the warranty!

I'm supposed to pick the truck up in a week. All I can say is thank goodness I purchased the extended warranty.

 

 

Curious why Ford would R&D an engine to burn oil. Seems like it would affect emissions........................../sarc.

Fortunate you had good records to fight the warranty company......their deflaut is usually no.

 

Did the stealership give any reason for the scored cylinders? And how many miles when the plugs started fouling?

And this case PROVES that high oil consumption isn't normal and has a cause.

Yes, excessive oil consumption is bound to play hell with emissions! The EPA should get involved when it becomes common in certain vehicles.

 

I had the plugs replaced at around 60k miles. The #8 plug was "wet" then, but the dealership didn't investigate further. Misfires/cylinder scoring occured at just under 70k miles. When I pick up the truck and go over the service with the advisor I'll ask why they think the issue occurred. Note that I've babied the truck in my 36k miles of ownership (no trailering, off-roading, etc.) so I'm guessing a design/factory/previous owner issue.

 

I know that there were some bad 5.0's in the 2011 and Early 2012 Mustangs, #8 was burning up, mostly in tuned motors but is happened in some stock motors also and then there were others that were drinking oil. Some were getting the dipsticks, oil caps and drain plugs taped up and told when to bring them back.

 

i have a 2011..i developed a knock on cly 4 or 6 @ 25k miles ( pass side most rear cyl) got a short block replacement under fac. bumper to bumper. ran like a top before and still running like a top after w/o the knock! hope all fairs well for you!

 

2011 and early 2012 had a problem with the casting of the engine block causing a knock. When was your 2012 built?

 

Using a quart of oil every 5000 miles is considered acceptable by all manufacturers. Even on a new truck the manufacturers wouldn't consider it a warranty issue unless it were 1 quart in 1000 miles. Granted MOST trucks today do better than that. I'm usually 1/2 qt low when I change oil. But if I've been towing or pushing the truck a little hard it could be as much as quart low. I've never had to top off before oil changes though.
