Looks like Ford tore apart a '03 4Runner and examined its electronics. Interesting read.

Sounds like Ford is trying to get a SUV that Ford Lovers will want to buy. Toyotas are way more reliable and the majority knows that. Ford has a lot of other luxurious items being offered but the mechanical part of their vehicles don't last as long as Toyotas. Personally I will never get me a FORD SUV. Only if Toyota's made trucks that can fit a nice size camping trailer will I get a full size Toyota Truck, the Tundra is not big enough for camping trailers.
