Transmission Control Module Software Defect
The 2022-2023 Express vans equipped with the 4.3L V6/8-speed automatic or 2.8L turbodiesel/8-speed automatic combinations have defective transmission control module (TCM) software. The software error can cause harsh shifting, sudden deceleration, and the vehicle moving in an unintended direction from a stop. GM received 18 harsh shifting complaints and 5 sudden deceleration reports.
GM recall affecting 54,722 Express units. Dealers reprogram the TCM with updated software that corrects the shift logic. The repair is performed free of charge.
Est. Cost: $0 (recall repair)Rear Wheel Momentary Lockup
The transmission control valve can fail, causing a brief lockup of the rear wheels or a sudden change in vehicle direction at low speed. This is related to the TCM software issue but involves physical wear in the transmission control valve body. The condition is most likely to occur during low-speed maneuvers.
GM safety recall for TCM software update and, if wear is detected, transmission control valve body replacement. Dealers install updated software that monitors valve performance and detects excessive wear before lockup can occur.
Est. Cost: $0 (recall) - $2,000 (valve body replacement)6.6L V8 Engine Wiring Harness Short Circuit Risk
Express vans equipped with the 6.6L gas V8 engine may have a wiring harness susceptible to short circuits. If a short occurs, drivers may receive a low battery voltage warning, the battery may die, or in worst cases, a fire can start in the engine compartment. This is a serious safety concern, especially for fleet and commercial operators.
GM recall for inspection and replacement of the affected wiring harness section. Dealers install protective conduit over the vulnerable wiring to prevent chafing and short circuits. Free of charge under recall.
Est. Cost: $0 (recall repair)Aging Platform Reliability Issues
The Express is based on a platform dating back to 1996, and the 2022 model retains many legacy components. Owners report issues with door hinge and latch mechanisms, rust in the rear cargo area and undercarriage, power window regulator failures, and cooling system leaks from the water pump and radiator. ABS module failures are also common.
Replace door hinges and latches as they wear. Apply rust prevention treatment to the undercarriage. Replace the water pump and radiator hoses as preventive maintenance. ABS module repair or replacement for brake warning light issues.
Est. Cost: $200 - $1,500 depending on componentFuel System and Emissions Problems
Owners report check engine lights related to the evaporative emissions (EVAP) system, including faulty purge valves and gas cap seal failures. The fuel level sensor can also malfunction, causing inaccurate fuel gauge readings. On diesel-equipped models, the diesel exhaust fluid (DEF) system can trigger derate conditions.
Replace the EVAP purge valve and gas cap. Replace the fuel level sending unit for inaccurate gauge readings. For diesel models, DEF injector and tank heater replacement may be needed. Clear and relearn the ECM fuel trims after repairs.
