Recently I dropped my 2009 Hyundai genisis 4.6 Leiter to get a few light bulbs changed. When I received my vehicle after completion, the light was still out, and the bumper cover was out of alignment. I started the engine and the check engine light was on. They corrected everything. The following day check engine light came back on. Took it back to dealer. After 2 days I called, was told the ECM & MASS AIR FLOW SENSOR were bad and needed replacement. Pickup vehicle from them, as I was told by service manager Jackson, they could not help me.
Took vehicle to Williams Auto and he went directly to the problem.
When they removed the air cleaner, the wires to the mass air sensor was pulled out. Didn't use the connector to properly disconnect the fitting.
Fortunately, I returned to auto nation and was reimbursed for the repairs.
Please find some mechanic who has as much pride in your vehicle as you do.
I don't recommend this service department to anyone. read more
