So it seems that GM cannot get it's act together, meanwhile the value of our cars keeps going down and if you try to sell your car prospective buyers stay away because of these issues. So what's next? Class action lawsuit?
What is there to sue about? They are trying to fix the problems, if you have a car that has continual issues work thru the Customer Service and be proactive, they have bought back cars before. This is why we have warranties.
No matter what car you buy, they all depreciate, and all of them have some problems, some more than others.
If anyone hurt the value of diesel cars, it would be the VW folks that did the most damage to the perception of diesel cars.
