Chevy problem caused by driver?

This bulletin applies to 2012 and prior GM passenger cars and light duty trucks. When diagnosing a power steering fluid leak, the technician may find a heat damaged fluid reservoir.

This is likely the result of over-heated fluid, caused by holding the steering against the stop/end of travel for more than five seconds at an engine speed of 1,500 rpm or more; doing continuous spin-outs with the steering against the end of travel or close to the end of travel for more than five seconds at 1,500 rpm engine speed.

After replacing the pump, educate the customer and advise against this practice.

Evidence of plastic reservoir heat distortion is a direct link to overheated power steering fluid, most likely caused by the driver holding the steering against its end of travel for too long.
