I drive the vehicle listed above which broke down about a month ago. Now, prior to breaking down I had noticed the engine had been behaving abnormally including being warmer than usual when driving, slower to accelerate, and most notably not allowing me to drive over 45mph without experiencing a “shuddering” motion. After getting it checked out by the mechanic he told me that 1 of the actual cylinders had blown causing the car to go into “reduced power mode”. I don’t feel safe driving the car at all now but I’m still making payments on it so I can’t just buy another vehicle at this time. However, recently I found a used engine from a 2016 Buick Enclave for around $2,400.00 my question is, would this used engine still be a compatible replacement for my car even though the year and make is different? Thank you!

From what I can tell the Enclave comes with a 3.6L 6 cylinder engine and you have a 4 cylinder turbo charged engine. If this is correct, I would not try it. I am sure it can be done but this will require new wiring harnesses, control modules, and some custom work to get the engine to fit. Meaning you will need to move engine mounts not to mention change the bell housing (at least) of the transmission to get it to fit. In other words, this would cost far more then just replacing the engine.

Looks like GM is selling direct replacements for about $3,800.00. Then add a few hundred for installation and you will still be cheaper and faster then trying to make the other engine fit in your vehicle.

Sorry for the unfortunate news but I have just seen too many people make this mistake. Unless you are will and able to make all the adjustments needed to make this work, I would not go down that road.
