What really blows about the 3 Amigos... well, there is more than 1...
1) Can't read the codes with an OBDII scanner or anything, so most owners are at the mercy of a shop. Unless you buy a reader yourself, which is a wise investment, but most don't.
2) Many get suckered into paying $1000's for a new modulator, when in reality there is a $0.50 fix. Just last week I was at a Land Rover shop. The owner told me he was aware of the cheap fix, but didn't like to talk about it because "then I wouldn't sell any more modulators".
3) Many of the faults are intermittent, and come on for almost no reason. If you could reset the 3 Amigos somehow, like disconnecting the battery, you could carry on. But you can't. You HAVE to have a computer of some sort to reset it, and get your ABS brakes back. That's tragic. Frankly, I don't know why the system hasn't been recalled. It is a safety issue to lose your ABS brakes.
But, at the end of the day, there is still no other truck I would rather drive. I've driven a number of trucks, and I hate them all. I'm not a truck guy. For me it's a means to an end. Nothing else (save maybe a Range Rover) drives like a Disco.
