Now they have officially launched a class-action against General Motors that could take years to play out, the parents of Nick Baker say they are hopeful it will bring some justice for their son.
The 22-year-old was killed in October 2012 when he lost control of his car and the airbags failed to deploy in the collision.
For a year-and-a-half Suzanne and Danny Baker had no answers for why that collision happened. There was no alcohol involved and speed was ruled out as a factor.
They now believe a faulty ignition switch at the root of General Motors' recall of 2.6 million vehicles also caused the death of their son.
Their lawyer, Russell Molot, said it is very likely they'll be certified and Nick Baker's name will be at the front of action against General Motors but it could take several years for it to be completely settled, whether that happens in court or in an out-of-court settlement.
"I don't care if it takes 10 years, I'm just doing it for my son, to rest him in peace," said Danny Baker.
His wife Suzanne Baker reiterated that point, saying they want only to find justice for Nick. She said even when the lawsuit is complete there won't be peace for her as a mother.
"From now 'til then, or even as it ends, I don't know that it'll ever really settle me because for the rest of my life I will miss my son, Nick," she said.
There is a possibility other families will join the lawsuit, whether they've suffered a loss or severe injury. It is believed four deaths in Canada are linked to the malfunctioning ignition switch and another 13 in the United States.
The Bakers said they will welcome the other families and work with them for an answer.
"All we can do is comfort each other and we can just be there for each other as we go through this," said Suzanne Baker.
"It's a horrible thing to have to get together with people over the loss of your child," she said.
The suit is seeking punitive damages totalling $500 M but the Bakers say this isn't about the money, it's about finding justice for Nick.
