Fuel Pump problems of the 2011 Chevrolet Equinox

I received a letter from Chevrolet (July 2013) explaining that there are issues with numerous engine parts, particularly the fuel pump and balance chain. Chevrolet stated that they are extending my power train warranty to 10 years or 120,000 miles, whichever occurs first. I have had the balance chain replace twice already. I am concerned that the condition with the fuel pump could cause a fire or serious engine damage. The letter from Chevrolet states: "in addition, the fuel pump plunger shaft seal may wear and allow fuel to leak into the crankcase, which would illuminate the malfunction indicator light. This can cause run-on and/or the engine to run rough". I would assume that the engine and oil in the Equinox would reach very high temperatures when they have been operated for a period of time. The introduction of fuel into the crankcase and engine could possibly ignite. Also the failure of the balance chain could cause engine failure under some driving conditions that could leave the car inoperable, causing an accident. I believe chevy should be held accountable for the defective parts and potential danger their failure could cause. Chevrolet should be directed to issue a recall to replace these defective parts. .
