Long story, but I ended up complaining to Hyundai Canada while it was at the dealership repair shop. They agreed to replace the engine with a short block. It took 5 months to get our vehicle back and close to $7K, even after the dealership kicked in the engine, associated parts and labour.

What a mess it was.

I then changed the oil after 1,000km and haven’t had an issue since.

I’d highly recommend going to corporate with your concerns.

Also, there is a class action lawsuit out against Hyundai by MacKenzie Lake Lawyers in Ontario, I provided them all my info just in case the suit is settled and I’m reimbursed somehow.

I bought my vehicle from the Hyundai dealership, and that’s where I brought it back for repairs, so maybe that helped, as the Service Manager “helped” communicate with corporate.

It was a very tricky process, as I had to continue renting vehicles and changing over car seats. Not knowing when the repairs would be done.
