I took my Civic in for a routine oil change/82k mile check-up, at which it was determined that the car needed a motor mount replaced as it had broken (How? No clue.). My rear brake cylinders were also deemed as leaking. This repair cost over $700, and I thought I was fine. Less than one week later, my heater ceased its proper functioning, but the engine temperature did not fluctuate (it remained normal). I took my car in today, and Honda determined that my head gasket is leaking and prompted its immediate repair. Thankfully I have an extended warranty, so there is no cost to me, but I'm rather frustrated. Wouldn't the head gasket leak have been noticed when the motor mount was fixed? I love my Civic, but I'm having trouble trusting Honda, or at least its mechanics...
