Disappointing. Paid over $100 for an A/C diagnostic. Took the Sonata to Creech, and called them to let them know the A/C compressor clutch was not engaging, which typically means the A/C compressor is bad. Diagnostic stated that power was not getting to the compressor likely because it was low in Freon. I took it another location and they replaced the compressor, and added dye to the Freon. No evidence of a Freon leak.
Was also advised of a timing cover oil leak. Other location diagnosed as head gasket oil leak, and replaced. No evidence of a timing cover oil leak.
Not sure what the value add of the $100 diagnosis was. I have spent thousands of $ at Creech in the past; expected more based on past experience.
