I have a 2012 Chevy Cruze that I purchased brand new. 1.4L Turbo, along with a trifecta tune and Injenz cold air intake system. When I bought my car it had no miles on it and now that its hit 37,000 the motor has blown for the (Second) Time! Ever since I installed the CAI and the Tune my car was now a (Modified) car. All of this was done around the 20,000 mark and ever since then I was told that Its important that I only put (93) Octane at the pump. The carwas performing extremely well until the 34,xxx mile mark when one day I was on the interstate with cruise control set to the speed limit (65mph). All of a sudden the car hesitates terrible then all my dash lights come saying service ASAP, then smoke poured out of my exhaust. I got the car towed into the dealership, where they told me that cylinder (4) had been melted along with the piston and the engine wall had been scorched. Took about a month before I finally had my car fixed from the dealership. They said they put a brand new crate motor in, however they Lied! They did a bottom half job and reused most of the old parts off the blown motor! (I know because I have been all over the cars engine bay many time times!) the dealership left me with, an oil leak and the car had been acting up. The dealer said its fine so I just drove it. Ever since I got my car back with the supposedly new motor I have been putting (93) octane in. Drove it to the 37,000 mile mark when once again on the interstate Going the Speed Limit the car repeats exactly how it acted the first time the motor blew. Had to have it towed again to the dealership, where they told me that cylinder 3 had been melted and damage to cylinder 4 as well.
My question is that do you think that the cruze being a (4) Cylinder, me putting Nothing But 93 Octane of pump gas in it, is what caused my motor to blow? The first time the motor had blown the cause if it was a vacuumed line had some how popped off on me while I was on the interstate which it sucked so much air in, causing it to run so lean that it melted the piston. I had been pulling Engine running lean, cylinder misfire codes on and before the first motor job.
