Far fewer recalls than the launch year, but two separate GM programmes will replace a 6.2L engine outright.

Recall 26V085, opened in February 2026, covers 2022 Suburbans with the ten-speed automatic and Electronic Transmission Range Select whose transmission control valve may fail and lock up the rear wheels. Dealers install new transmission control module software free. The same underlying wear is covered on the repair side by GM's Special Coverage for the control valve, which runs fifteen years or 150,000 miles and pays for a new valve body — the symptoms it lists are harsh shifting, a service-engine-soon message, reduced engine performance and code P0747. This is a recent campaign, so a truck that has sat unsold may well be outstanding.

The 5.3L avoids the connecting-rod recall entirely, which is the main reason to prefer it — but it has its own cylinder-deactivation problem. DFM, Dynamic Fuel Management, can shut down any combination of the eight cylinders and uses collapsible lifters that stick or collapse, scarring the camshaft and turning the repair into lifters plus a cam. Mechanics report DFM failing more often and earlier than the older AFM (Active Fuel Management) design. There is no recall for it. Cold-start the truck and listen for a tick or tap before it warms, and treat a stored misfire code as a reason to keep looking.

This is the most checkable 2022-specific item and the easiest to be caught by. GM ran a series of Customer Satisfaction Programs because the semiconductor shortage meant trucks left the line with features non-functional: heated and ventilated front and rear seats on builds from 15 November 2021, a heated steering wheel from 17 November 2021, park assist from 2 December 2021, and front seat-cushion ventilation blowers from 30 March 2022. GM's own wording is that buyers should have been told at sale and would be eligible for a no-cost retrofit once parts were available. Press every button. A truck sold twice since new may have lost that story.

Two small free programmes worth knowing about if you tow or if the truck sits. A Customer Satisfaction Program covers a Service Trailer Brake message that appears when a trailer with electric brakes is connected and the driver uses the manual slider or the brake pedal; dealers replace the trailer brake control switch. A second covers a battery that can drain after an over-the-air software update, sometimes showing a Download Paused message on the radio — dealers charge and test the battery, replace it if it fails, and reprogram the serial data gateway module. Neither is a safety recall; both are free.

The independent rear suspension introduced in 2021 carries into 2022 with the same wear items. On air-suspension trims, hands-on teardowns show the compressor seizing with its piston scored by grit and moisture, and the units are not practically rebuildable — one mechanic's view is that they will eventually fail regardless of brand because of where they sit under the truck. Coil-sprung trims sidestep it. Park an air-sprung truck overnight and check it has not settled at one corner, and listen for a compressor that runs long or often.
