IF you can show in court--you'd have to file a lawsuit--by expert testimony (e.g. that of automotive engineers or similar professionals who have examined your vehicle) that the awning and associated circuitry was either designed or installed defectively, you can force the manufacturer to pay for the damage. However, it will take a lawsuit using expert testimony (which you have to pay for--i.e. for the expert's time) proving fault to do this; there is no mechanism other than suing and proving your case in court to get compensation. And you cannot recover the expert's cost--in our legal system, you have to bear that yourself, just as you would bear your own legal fee(s) should you hire an attorney. Only by proving fault in court can you get compensation.
