What owners wrote

Diesel truck computer system shuts down truck for minor def system error code to 5mph within 85 miles to get to a dealer to reset computer code. This will cause deaths from truck not going any faster than 5mph on freeway. Just because the def system sees an error and might cause a bit more exhaust, to shut down your truck in the middle of nowhere causing traffic nightmares and deaths is the most stupid rule the EPA and mfgs follow. Epa and mfg needs new computer programming on all diesel trucks that have this.
