I asked for a leaky transmission fitting to be addressed and the Murray GM service technician replaced all of the transmission lines. $600 cost for a $50 problem. Murray GM Service technician identified a crankshaft location sensor as the reason for an ABS and Stabilitrak warning light and offered to change it at a $500 cost. A second mechanic at a different location replaced a faulty tire pressure monitor sensor and fixed the problem. I'm fine paying for repairs that need to be done. I'm not okay with dealerships that pad service orders and provide incorrect information to customers.
