general problems of the 2013 Chevrolet Silverado 2500

Driving on the interstate the truck starting. Message center displayed a fuel sys warning. The messages changed warning of speed limitations. The speed allowed wa# reduced every few miles. Eventually the engine would not run nor would it restart.

Diesel exhaust poor quality warning false alarmed and began restricting vehicle speed thus limiting range the vehicle can travel to less than 250 miles and at speeds significantly lower than posted speed limits. Potentially leaving a motorist stranded or vehcile incapacitated when traveling distances greater than 250 miles from residence. 1st warning reduces speed to 65mph after 100 miles 2nd warning reduces speed to 55mph after 75 miles 3rd warning reduces speed to 4 mph after 75 miles the warning light has appeared on the vehicle on 3 separate occassions and never due to def being expired or old. On all three occasions vehicle was taken to local Chevrolet service department for repairs. First incident January 10th 2022 replaced 2 thermastats, second incident February 9th 2022 added fresh fuel, third incident April 1st 2022 replaced secondary nox sensor. My safety is at risk if I were to use the vehicle to travel long distances, use the vehicle for towing or attempt to travel on the interstate. No assurances have been made by Chevrolet that repairs have truely fixed the issue as it continues to recur and each time I am being charged by dealership for different repairs. The issue has been reported to Chevrolet customer care whom have been difficult to communicate with, only agreed to re-imburse $41 of the over $2000 in repairs, and do not seem to care about my safety concerns.

Metal shavings in my fuel system.

Poor quality exhaust fluid unable to drive over 55mph.

We have had two sets of fuel injectors replaced and a fuel sensor put in. Just turned 83000 miles and now the code p11db is showing which is the nox sensor, not covered by warranty even with all the fuel system issues we've had.
