Car on fire 5 mins out of the dealership

r/

Location: Ontario, Canada

I had our car serviced yesterday at the dealership. Also, had the diagnostics done. They called me saying valve cover gasket needs replacement and I give them an okay to go ahead. I picked up my car in the evening. They said everything is good. Nothing in the diagnostics. Car is in great condition.

I leave and within 5mins, there’s white smoke. I thought let’s turn around since I’m so close and take the car back to the dealership. It’s getting worse, so I shut the car down and barely escape in the middle of this busy intersection and it’s on fire.

What legal action can I take? I’m extremely shaken up and honestly scared of driving now.
