Common problems reported by 2022 Chevrolet Suburban owners, with recommended fixes and estimated repair costs.
DFM Lifter Failure on V8 Engines
The Suburban shares the same T1XX platform and V8 engines as the Tahoe and Silverado, and suffers from the same DFM lifter collapse issue. The 5.3L L84 and 6.2L L87 engines are affected, with owners reporting lifter failures at very low mileages. A 2022 Suburban RST was documented with lifter failure at just 6,500 miles.
Dealer replaces the failed lifters, VLOM assembly, and camshaft if scored, under powertrain warranty. GM's Component Coverage program provides extended warranty for repeat valve train repairs. Reference TSB 15-06-01-002F for proper diagnosis.
Est. Cost: $1,500 - $4,000 (typically covered under warranty)6.2L V8 Connecting Rod and Crankshaft Defect
Identical to the Tahoe, certain 2022 Suburban models with the 6.2L V8 have potentially defective connecting rods and/or crankshafts that can cause catastrophic engine failure. The defect is a manufacturing issue and is not related to owner maintenance or driving habits.
NHTSA Recall N252494000. Dealers inspect the engine and repair or replace as necessary. Vehicles that pass inspection receive preventive measures including higher viscosity oil. All work is free of charge.
Est. Cost: $0 (recall repair)10-Speed Transmission Harsh Shifting
The 10L80 10-speed automatic transmission exhibits harsh shifting, shuddering during light acceleration at highway speeds, and delayed shifts. The transmission may also produce clunking sounds during low-speed gear changes. In rare cases, the transmission control valve can wear to the point of causing rear wheel lockup.
Recall N242454440 for TCM software update to monitor transmission control valve wear. Transmission fluid flush with updated Mobil 1 Synthetic LV ATF HP fluid for shudder symptoms. Valve body or complete transmission replacement for vehicles with internal damage.
Est. Cost: $0 (recall) - $4,500 (transmission replacement)Third-Row Seat Belt Buckle Rivet Defect
The rivet retaining the seat belt buckle to its bracket in the third-row may be improperly formed, potentially causing the buckle to fail during a crash. Given that the Suburban is frequently used as a family vehicle with all three rows occupied, this defect is particularly concerning.
GM recall for 2021-2022 models. Dealers inspect and replace the third-row seat belt buckle assemblies as needed, free of charge.
Est. Cost: $0 (recall repair)Electrical System and Infotainment Glitches
Owners report infotainment screen freezing, rearview camera intermittent failure, random warning lights on the dashboard, and wireless phone charger overheating. The large 12.3-inch digital instrument cluster may also experience intermittent blackouts or display artifacts. Battery drain is reported on vehicles that sit for several days.
Software updates to the infotainment and BCM modules. Battery replacement if the 12V battery tests below specification. Wireless charger module replacement if overheating occurs. In severe cases, the instrument cluster or infotainment unit requires replacement.
Est. Cost: $0 (software update) - $1,800 (module replacement)
