Bought my 2007 Impala with 53,000 miles 6mo ago. Forth time having it serviced and only at 63,000. PCM failed after 4 months which hydrolocked my engine. Hydrolock caused fuel injectors to go and a bent piston. Had my car back for 24 hours after 2nd fix of engine problems and engine light is back on. GM unwilling to help any further. This was my first GM product and my LAST.. Owned a 1999 Dodge for 160,000 miles and no where near the problems I have experienced in just 10,000 miles with my Impala.
