If that $37,500 is per day until they resolve the problem for every violating vehicle in the US then that whole “offering a new car at discount” idea seems like it is for total suckers, right? Eventually it’s going to be more economical for VW just to fix your car or give you a new one unless the Justice department thinks offering customers a coupon is a good faith solution.
The violation cited there is of the reporting obligation, and it’s $37,500 in total, not per car (the other remedies sought are per car). I’m not sure when exactly the cut-off would be (the claimed violations relate to applications for certificates of conformity, so presumably from the date of application to the time VW provides the required information, but the lawsuit doesn’t say whether they have yet done so. Regardless, the claim is small change compared to the first three.
