This is a safety issue because the truck suddenly loses power and cannot accelerate normally.  The most serious incident occurred while driving over Santiam Pass in Oregon. The vehicle went into reduced-power/limp mode on a mountain highway, leaving me unable to maintain normal speed or accelerate safely. I lost power needed to pass traffic and had limited ability to respond to road conditions.  The problem has happened several times. It has also occurred while I was towing my boat, which left me unable to continue the trip safely and created a hazardous situation because the truck could not maintain normal towing power.  The issue appears related to the diesel particulate filter/emissions system and repeated DPF/regen or exhaust aftertreatment problems. I am concerned that a design, calibration, or emissions-system defect is causing sudden power reduction during normal driving and towing. This creates an unreasonable safety risk, especially on mountain passes, two-lane highways, and while towing.  I am requesting that NHTSA review this as a potential safety defect involving the 2018 Chevrolet Colorado diesel DPF/emissions system and reduced-engine-power strategy. I am also requesting that this complaint be considered with any similar complaints, recalls, technical service bulletins, or emissions campaigns related to DPF regeneration, particulate matter sensor diagnostics, reduced engine power, or limp mode on the 2.8L Duramax Chevrolet Colorado.","products":[{"type":"Vehicle","productYear":"2018","productMake":"CHEVROLET","productModel":"COLORADO","manufacturer":"General Motors, LLC"}]}]}
