Hi there.

Going by your post, it looks as though there is a fault code that has not been repaired and that's preventing the OBD monitors from completing during the drive cycle.

Any qualified Emissions technician should be able to address this issue - the fact that your mechanic can't seems to indicate he does not have the technical knowledge to do so. My advice at this point is for you to ask for a refund and take your vehicle to a qualified shop where they're familiar with and have the necessary tools to work on your Hyundai.

Optionally, I could guide you or a person of your choice through the correct diagnostic and repair procedures - please be aware that whomever gets to perform the procedures would need access to tools such as a capable scanner, scope, etc. and the skills to use them.

Best Regards.

Thank you Juan Crespo. I have felt that I need someone more qualified than the safety and emissions mechanic where I took my vehicle. He has me in the hole for over $500 in parts & labor already, then tells me he's at a loss & can't figure it out & for me to google it. What can I reasonably ask for as far as a refund?
Expert:  Juan Crespo replied 7 months ago.

Well, if you took your vehicle to him for the specific purpose of passing emissions, anything he has charged you for that purpose should be refunded - you should also report him to your local Better Business Bureau for shoddy business practice. People like him give us auto mechanics a bad name and should not be allowed to keep ripping off customers.

Best Regards.
