General Motors pulled the sheets on the fully refreshed 2022 GMC Sierra 1500 in October, revealing a long list of changes and updates. Notably, most trim levels for the refreshed 2022 GMC Sierra 1500 are no longer equipped with a 12-volt outlet, which could come as a surprise for those customers expecting to power their 12-volt accessories.
For now, the only refreshed 2022 GMC Sierra trim level to offer a 12-volt power socket is the base-model Sierra Pro, which, to be specific, is equipped with the front auxiliary, 12-volt power outlet (RPO code KD5). Meanwhile, all other trim levels of the refreshed 2022 GMC Sierra 1500 do not offer a 12-volt socket – at all.
By comparison, the 2022 GMC Sierra 1500 Limited and older model years for the light-duty pickup featured the front auxiliary, 12-volt power outlet as standard across all trim levels. What’s more, the GMC Sierra SLE, Elevation, SLT, AT4, and Denali trim levels also included the Rear auxiliary, 12-volt power outlet (RPO code KPA). To note, the GMC Sierra Pro did not include the Rear auxiliary, 12-volt power outlet.
Now, with regard to the refreshed 2022 GMC Sierra 1500, GM has expanded the availability of the Instrument panel, 120-volt power outlet (RPO code KI4) and Bed mounted, 120-volt power outlet (RPO code KC9), both of which are now optional for the GMC Sierra Pro trim, and included as standard for the rest of the lineup. These features were previously offered as optional for Pro, SLE, and Elevation, and included as standard on SLT, AT4, and Denali.
With that in mind, customers eager to use their 12-volt accessories with the refreshed 2022 GMC Sierra 1500 may need a third-party adapter to do so.
As a reminder, the refreshed 2022 GMC Sierra 1500 is offered with four engine options, including the turbocharged 2.7L I4 L3B gasoline engine, the atmospheric 5.3L V8 L84 gasoline engine, the atmospheric 6.2L V8 L87 gasoline engine, and the 3.0L I6 LM2 turbodiesel Duramax. Under the skin, the GMC Sierra 1500 rides on the GM T1 platform. Production takes place at the GM Fort Wayne plant in Indiana and GM Silao plant in Mexico.
