It did scare me tbh, but then it would anyone!!!!!!! This happened a while ago, the Fire Chief did his report and said it was an electrical fault, because I had Finance on the car, after this event I then refused point blank to pay for a car I could no longer use, also something that wasn't fit for sale (unfit for use act) I was then in lenthly meetings with the dealership/Toyota UK and Toyota Finance, and none of them would admit Liability, so I had no choice but to Claim on my Insurance, to which it put my premium up. I then got the Financial Ombudsman involved and I couldn't ask for a better service, they sent an investigation officer to see the remains for there report , and they confirmed the Fire Chief was right. Toyota UK then sent a independent asesser out but they were not playing ball so to speak, subsequently they then destroyed the evidence and had it crushed, this then made my case with the ombudsman even stronger as they were obviously trying to cover this up. In the end after a lot of going Forwards n Backwards I won my case, they wiped off any outstanding Finance and got £1000.00 compensation, I would always recommend the Financial Ombudsman even if it's just for advice.......
