This thread is becoming a little crazy. There is no recall here. That Honda might be willing to step up on a catalytic converter or safety belts has no bearing on the question of the engine block potentially cracking. It is not reasonable and is wishful thinking to think that Honda will take part in a warranty on a salvage car. Similarly, the idea that that the dealers will not check title status prior prior to replacing a $10,000 engine on an eight year old car is willfully ignorant. If you buy a salvage car, you need to know that you are on your own. (Even more so than you are in buying an eight year old vehicle.
Some earlier poster made a comment about salvage title cars being rebuilt poorly, and suggested that it was the norm. The fact is that cars are often totalled for solely economic issues. A car that depreciates quickly, is more vulnerable to being totalled. Insurance companies (wisely) may shy away from putting a heavily-damaged car back on the road. All that said, there are plenty of situations where salvage cars are repaired well, inspected, branded as reconstructed and put back into service at a substantial discount to the new owner.
