General Motors has released a service bulletin for select units of the 2020 Chevy Colorado due to an issue with a solenoid that’s prone to failing.
According to Special Coverage bulletin N232430470, certain 2020 Colorado units equipped with the naturally aspirated 3.6L V6 LGZ gasoline engine may have a condition where the engine’s bank two camshaft position actuator valve solenoid could fail. If this were to occur, the Malfunction Indictor Light (Check Engine Light) will illuminate and a Diagnostic Trouble Code (DTC) will be set.
Affected vehicles are to be inspected by certified GM technicians, while the bank two camshaft position actuator valve solenoid will be replaced as necessary, free of charge. Notably, it should take GM techs roughly almost four hours to complete this fix.
It’s worth noting that this bulletin is classified by General Motors as Special Coverage, which means that affected vehicles will be covered 15 years or 150,000 miles – whichever comes first – from the date the vehicle was originally put into service, regardless of ownership. This means that any eligible claims that are filed on or after January 25th, 2024 must be submitted using labor operation codes. As for claims filed before this specific date, repair orders must be submitted to the Service Contract provider.
As a reminder, the 2020 Chevy Colorado was offered with the choice of three engine options. These included the naturally aspirated 2.5L I4 LCV gasoline engine, rated at 200 horsepower and 191 pound-feet of torque, the Duramax turbodiesel 2.8L I4 LWN engine, rated at 181 horsepower and 369 pound-feet of torque, and the naturally aspirated 3.6L V6 LGZ, rated at 308 horsepower and 275 pound-feet of torque.
Transmissions choices consisted of either the GM six-speed automatic transmission or the GM eight-speed automatic transmission. Meanwhile, 2WD was standard and 4WD was optional.
