I4 Ecoboost Engine taken in for service after 2570 miles... engine misfire

Recommended Posts

Just leased a 2015 Ford Edge SEL with the I4-Ecoboost engine. I was really enjoying it until I tried to pass a car on the freeway and lost all acceleration. The gas pedal went to the floor and the car never moved. The "Service Engine" light lit up and started flashing an amber warning. I decelerated and got off of the freeway and onto the service drive to stop. The car never stalled out and the light went off after a moment.

 

Took the car in to the dealership and they found that there was an engine misfire in the 1st cylinder. Upon further investigation, they found that the misfire happened due to engine coolant leaking into the cylinder head. Their solution is to just replace the cylinder head and send me on my merry way.

 

Should I let this be the end of it or should I demand either: A - a completely new engine; who knows what else is wrong with the engine after coolant has been racing through it. Or B - demand a new lease vehicle since it's only been 2,570 miles.

 

Anybody else hear of this happening? Has this happened to you? I'm curious to know because this is the 3rd Edge I've owned, but the 1st Ecoboost engine I've had.

You can demand a new engine, but you'll have to provide good evidence that the block is toast now.

You can demand a new lease, but it won't happen unless the vehicle is a lemon.

 

So keep a close eye on the vehicle. Any hiccups and take it to the shop ASAP. Keep record of when it is in the shop and for how long.

Do you plan on buying the car when the lease is up? If not why would you be concerned with a long term problem since I would assume your lease is through the warranty period.

That symptom sounds like the turbo hose blew off - common problem on the early 2015s. Was there any other symptom that would point to a leaky head gasket?

 

Unless it's been leaking for a long time a new head should fix it without damage to the bottom end.
