Laguna on fire

The Laguna of a colleague has recently risen into flames, without any obvious reason. He put his car (with just 45,000km of mileage) on his parking space, as always… I slept peacefully in the evening and was woken up unbelievably at night: “Your car burns. The fire department is already there…” You can exclude foreign influence, is probably spontaneous self-inflammation. The result were a completely burnt out Laguna and two other damaged vehicles. My question now: Has anyone heard of such incidents at Renault, how did Renault react to them and how did the insurance work? Isn’t this a case for a lawsuit against Renault or time for a letter to a major automobile magazine… I’ve already heard of burnt-down Clio`s (don’t know about it anymore…) Stand in front of you put the car in the garage and your house burns off!!!
