Chevy's New 1.5L Engines Are Melting Themselves | Shifting Lanes

The new 1.5L turbo engines are melting their pistons deeming them inoperable. The last thing you want from a new car is an engine that melts itself but some Chevy customers who drive the new Malibu and Cruze are experiencing just that. The 1.5L will turn itself into an even more economical three-cylinder giving you a rough ride, insane blow by, and a bad headache. It will take some time for GM to perfect the 1.5L but for the mean time, I would stay away from an engine that will deem your new car inoperable.

Chevy has some serious QC issues.

There is no date on the post, but the three comments are dated 21 & 22 Dec 2016.

The other thread linked above also cites this article.

There, J Blackburn replied,

This is old news. They have since been recalled. An ECU update and stipulation to use full synthetic Dexos 1 oil addresses the issue of low speed preignition in these engines. Basically they detuned the low end torque a little bit and slightly enriched the fuel mix.

Haven't heard of any issues with them since. The engine is also used in the new Equinox in a slightly higher state of tune than the Malibu (and frustrating transmission programming).

In addition, the Cruze doesn't use this engine. The Cruze uses a 1.4T engine.

Owners of this engine with this problem have posted to this forum as well. Widespread? Well, not yet. But this engine distribution is still relatively early.

I don't know this for sure, but some posters to this forum say the 1.4 and the 1.5 are the same engine but the difference is in the stroke length. That being said, it still might be hard to argue that the engine is still the "same".

Nope - the 1.5 is physically a little larger than the 1.4.
