Not really brand new cars though
I'm not sure what point you are trying to make I highlighted the 6 year old Stradale as it had managed to rack up over 20,000 miles without fault then due to an error by the owner almost went up in flames. Someone could just have easily dislodged the wiring causing the fault when that car was a few weeks/months old but didn't and that was my point. We don't know how old either 458 was, how they'd been driven/maintained/what caused the fire in each instance etc. It may be rogue build faults, component failure or owner error. I read recently about a Lamborghini Murcielago that burned in the US due to a poor aftermarket hi-fi installation. No doubt those pics caused people to say there goes another unreliable Italian exotic if they didn't realise it was due to the poor workmanship of an installer, not a factory issue.
Ferrari have been building the 458 since January so allowing for production ramp up it's probably safe to assume that over 1000 + examples have been delivered thus far. I'd therefore hardly call these two incidents cause for huge alarm as a percentage of cars in use.
It always looks far more dramatic when a Ferrari burns due to the extensive use of aluminium and plastic in these cars. Aluminium just disintergrates at high temperatures and the very nature of the design of mid engined cars ensures an engine bay fire gets plenty of oxygen to burn due to all of the cooling vents on th bodywork feeding it combined with rear decks that have a lot of air vents built in. In comparison a front engined family car/SUV etc has an enclosed steel engine bay that can only draw additional oxygen through the front grille and underbody thus restricting the sped of a blaze and making it easier to douse the fire before the whole car is engulfed.
