a fine of apparently $24,000 per vehicle plus the fine overall......
It could be a lot more than that Dave. The fine is $37,500 per violation, not per vehicle. As I read the NOV, it would appear that there are at least three violations per vehicle.* Multiply that lot up & you end up with an astronomical figure.
They may not apply all of the fines & maybe not the full amount either, but the Yanks are known to be hard on foreign companies.
GM of course are still reeling from the effects of the ignition switch scandal so this may be used as an opportunity to hit one of their competitors.
* 1) Fitting the "defeat device", which is a specific violation.
2) Not declaring the "defeat device" in the Certificate of Conformity. (CofC).
3) Supplying vehicles that did not conform to the CofC.
Forgot to add, class action lawsuits have already been raised, on behalf of affected owners, seeking full refunds plus damages!
