Engine Failure

[Rickybobby]

Anybody else have the engine block crack. My 2010 Maliblu with 46,000 miles on it has a cracked block and needs a new motor.

@Rickybobby, I haven’t read about others having this happen. Under normal circumstances this would be covered under the Malibu’s Powertrain warranty.

From my family to yours, we hope you have a wonderful Thanksgiving.

Blocks don't crack without a good reason. Any idea what caused it? I assume you have a 2.4l.

Greenman,
Is the 2.4l more prone for failures? I know freezing is a good way for things to break. Or over revving and tossing a rod out the side does it too Bruce

[Rickybobby]

Yes,2.4 liter. I'm going to dealer today to pick up car. They have installed a new motor and I'm going to ask them what caused failure.

No. I was just trying to establish which engine the OP has.

I've never lived where it freezes much so I have no experience with frozen blocks. I know all engines have freeze plugs that are supposed to blow & relieve the pressure. Throwing a rod will certainly do it.

Dealer has no idea what went wrong with motor. But it didn't cost me a dime. Dealer was great. Hope this motor will stay with me for a while.

Good to hear it was replaced. Just curious, how long did it take them to do it?

1 week I gotta say I've never been treated so well by a dealer.
