General Motors will conduct a Voluntary Emission Recall involving a selection of diesel models in order to address a potentially faulty exhaust particulate matter sensor.

The recalled vehicles in question include certain 2016 model year Chevrolet Colorados and GMC Canyons; 2017 model year Chevrolet Express and GMC Savanna vans; 2017-2018 model year Colorados, Cruzes, HD Silverados, GMC Canyons, and HD Sierras; along with 2018 model year Equinoxes and Terrains equipped with GM's new 1.6-liter diesel.

GM has decided to recall these vehicles in order to reprogram the engine control module which may not properly detect and diagnose a failure with the exhaust particulate matter sensor, should a failure occur. A subset of 2017 HD Silverados and Sierras may exhibit a condition in which the engine surges up to 2,800 RPM while coasting or braking, but only in extremely rare circumstances.

GM should begin notifying affected owners shortly, and your local dealer will be tasked with reprogramming the ECM, it's a process that shouldn't take much longer than an hour. GM also says eligibility for the ECM reprogramming won't be affected by the presence of non-GM parts or service work performed by third parties.
