As to what the exact nature of the problem is, Wilkinson wouldn't say, but he did say the recall was intended to prevent big issues down the line. "It was not a big problem," he said. "It was something we started to see in the warranty data, but it was one of those that you could tell over the life of the vehicle, there were going to be a significant number of battery failures. The life of the vehicle and emissions system is like eight years or 100,000 miles so that gives you some idea of it. As for the nature of the problem ... it's safe to say when you combine new technology, ramping up the new production line, putting the new vehicle into production, any quality control engineer can tell you there are numerous opportunities for small problems to crop up. Often, you don't find those problems until you've got volume production going and the vehicles are in service." Hopefully, Cobasys will clarify with us their issues as well.
