I bought one of the 2015 Chevrolet Cruze Diesels (LUZ engine code). I had to travel across states to get it. I liked it. I didn't understand why Chevrolet didn't advertise this flagship Cruze. Even on KBB it shows the Diesel as being the "highest priced" of all the trims. I think that's mainly because all of the diesels came loaded. Backup camera, moonroof, heated seats, climate control, Pioneer entertainment, Navigation, remote car starter from key fob, blind spot sensors, parking sensors, and even LED Daytime running lights.
My Cruze averaged 40-42 mpg at interstate speeds. The most mpg I received with the cruze was almost 50 right after I bought it. I can't say I ever had a problem with it except the front shutter door, which I think someone at the dealership broke before I took possession. It was a door that would block off the grill over 45 mph for improved drag coefficient and mpgs. The broken door caused a transmission code be set but in reality, once I had the shutter door fixed the codes never came back. I put 35k miles on the car before trying to sell it.
I liked the car with the exception of where they put the heater controls. I'm 6 foot guy and could move the seat far enough where I couldn't touch the pedals. There's something to be said for that kind of leg space. However the problem was where I needed the seat set to be able to reach the pedals, my knee could and would adjust the temperature of the climate control. Besides that and the Chevrolet dealership charging me for a "duramax" oil change ($89) because "it's a diesel", the car was reliable, quieter than any of my VWs, and a good car.
I returned to VW for the mods. When I called Malone about a tune for the LUZ 2.0L VM Motori Italian diesel engine made in Landstuhl Germany that was in the Cruze, they told me I was only the 3rd person to ask about it in a year. No demand meant no tunes. It was a good car if that's all you want it for, driving point A to B, no mods, no frills. About the only mods I was able to put on it besides scheduled maintenance was Window Tint, ClearBra, and mudflaps.
