General Motors announced a recall of certain 2013 and 2014 Chevy Cruze vehicles equipped with a 1.4L turbo engine, and manufactured between Nov. 28, 2012, and March 7, 2014.
Turbochargers are essentially compressors that direct more air into the engine’s cylinders in order to produce additional power. A turbo derives its energy source from both temp and pressure of exhaust gas. Intake air enters through the air cleaner into the turbo compressor inlet. The air is compressed which raises air density and volume.
Some F-Super Duty F-250/350/450 trucks equipped with a 6.7L diesel engine and built on or before 5/16/2012 may experience an engine shudder with or without turbo flutter noise around 900-1,400 rpm with steady throttle.
