This could be a very good thing too. I suspect they are going over them with a fine tooth comb. Think about it.. Publicly traded company whose fiscal year ends on 12/31. Everything thing is driven by revenue recognition. They could have shipped them out, recognized the revenue, and then done campaigns to fix whatever needs to be fixed. A reserve is taken to set monies aside to cover warranty repairs. And it is usually a higher percentage on a new product launch. (I worked for a class 8 truck OEM and that was normal practice)
At this point I'd rather them go over these potential problems and triple check everything before I get it, than to take delivery, drive it home and blow the engine, the differential or have a frame issue. And have to be down with some major repairs being done and showing up on my VIN report.....
