My Mazda 2011 CX9 would lose braking ability and intermittently die. I took it to a local mechanic (Mike the Mechanic) who diagnosed it as having defective brake booster diaphragms and informed me that Mazda had extended the warranty for this issue. He was kind enough to only charge me half of his posted diagnostic fee.
I contacted Jim Ellis Mazda of Marietta to schedule an appointment to have the repairs performed along with two recalls. They scheduled a Saturday drop off with a Monday service along with a loaner car to use during the two to three business days the repairs would take.
When dropping the car off on that Saturday they were surprised I was promised a loaner. They contacted Enterprise for me to obtain a loaner and two hours later I was on my way.
The following Wednesday Jim Ellis called to inform me that the check engine light was caused by two defective oxygen sensors and provided an estimate of $473 each. This came as a shock because the check engine light was not on when we took in the car.
I contacted my new friend Brian at Mike the Mechanic for advice. He informed me that most likely the error codes were generated when the unit kept dying from the brake booster diaphragms, and they would probably clear with time or by disconnecting the battery. If that was not the case, he could replace both sensors at less than half the price quoted by Jim Ellis Mazda.
We declined the repair offered by Jim Ellis and asked them to just perform the brake booster repair and the two recalls. We were called the following Monday (ten days since dropping it off) to pick up our vehicle. We promptly picked it up and there was no check engine light. My conclusion is that either Jim Ellis was attempting to take advantage of us or else they are just plain incompetent.
It has since passed emission testing which I believe it would not with bad oxygen sensors
