Quieter than the launch year but the engine problem hardens — and this build gets a second GM programme whose remedy is a new engine.

Recall 26V085 covers 2022 Tahoe, Suburban, Yukon, Yukon XL, Escalade and Escalade ESV vehicles "equipped with 10 Speed Transmission with ETRS (Electronic Transmission Range Select)" where "the transmission control valve may fail and lock up the rear wheels." Dealers install new transmission control module software free. VINs became searchable on NHTSA on 12 February 2026 and owner letters were mailed on 7 April 2026, so this is a recent campaign and completion on a used truck is unlikely. Separately and more valuably, GM's Special Coverage for control-valve wear runs fifteen years or 150,000 miles from first service and pays for a new valve body outright — the symptoms it lists are harsh shifting, a service-engine-soon message, reduced performance and diagnostic code P0747. Drive for shudder and harsh shifts, and ask whether the valve body has been done.

Recall 25V619 is unusual and specific: it covers certain 2021 Escalade, 2021 and 2023–2024 Tahoe, and 2022 and 2024 Yukon vehicles with the six-cylinder diesel where "the original fuel tank may have been replaced with an incorrect fuel tank, which can allow fuel to leak in a rollover crash." Dealers inspect for the correct tank and replace it if necessary, free. Because the defect was introduced by a service replacement rather than at the factory, it does not follow a clean build range — which is exactly why it needs checking by VIN rather than by reasoning about the model year. Owner letters were mailed 5 November 2025 and VINs became searchable on 18 September 2025. It applies only to diesel trucks.

The 6.2L gets a recall and two coverage programmes. The 5.3L gets neither. DFM — Dynamic Fuel Management, which can shut down any combination of the eight cylinders — uses collapsible lifters that stick or collapse, and a failed one scars the camshaft, so the repair is lifters plus a cam. Mechanics report it failing more often and earlier than the older AFM system it replaced, and there is no recall and no special coverage covering the 5.3L on this model year. The only GM programme in this family that pays for an engine reaches the 2023 build. Cold-start it, listen for a tick before the engine warms, and treat any hesitation as the engine switches between cylinder counts as a reason to look harder.

The semiconductor shortage hit this build directly, and GM's own words are unambiguous: "Due to the industry-wide semiconductor shortage, the front heated/ventilated seats, front heated seats, or rear heated seats are not functional on certain 2022-2023 model year vehicles listed above, built beginning November 15, 2021. The affected vehicle owners should have been made aware of the condition at sale, and notified that once parts are available, they would be eligible for a no additional cost retrofit." Separate programmes cover the heated steering wheel on builds from 17 November 2021 and park assist on builds from 2 December 2021. A used buyer three owners downstream may never have been told. Compare the window sticker against what actually works, and if something is missing, the retrofit is free.

Two GM programmes cover small faults with irritating symptoms. The engine coolant control valve can fail an on-board diagnostic test, lighting the check-engine lamp and setting a code, and "in some cases, the engine cooling fans may run after the engine is switched off" — the valve is replaced at no charge on 2021 through 2023 trucks. Separately, several satisfaction programmes cover a battery that "is at risk for a drain following an over-the-air update," fixed by reprogramming the serial data gateway module and the radio; one of them adds that a "Download Paused" message may appear on the radio display, and that dealers will charge and test the battery and replace it if it fails. If the truck has been sitting on a lot with a flat battery, this is the first thing to ask about.

Two towing-and-suspension items with documents behind them. GM's Customer Satisfaction Program N222384930 covers a "Service Trailer Brake message set when a trailer with electric brakes is connected and the driver attempts to use the manual apply slider on switch or depress the brake pedal while towing" — code C159C, remedied by replacing the trailer brake control switch. On air-suspension trucks, a GM bulletin describes "the air levelling suspension losing air pressure in very cold temperatures while sitting for several hours," with dealers replacing both front air springs; another covers a pinched air inlet hose to the compressor setting code C1197. Two mechanic teardowns give the pattern that costs most: a leaking spring makes the compressor run constantly until it fails too. Test the trailer brake controller, and park the truck overnight in the cold if you can.
