TSBs only are covered if the vehicle is under warranty vs a recall that is fixed for all vehicles because of a safety issue. That being said would it be a compelling argument that if this happens during driving that it could be considered a safety issue? Hard to say. But with the amount of people having the same issue around the same mileage you would think there would be some official response to who will be covered and who will not. There’s conflicting info that some people have had it replaced at no charge and others paying close to $1800.
