The 2022 Traverse with the 3.6L V6 is mostly solid for a three-row SUV, but GM's long-standing AFM/DFM (cylinder deactivation) system creates real engine durability concerns that can turn catastrophic if ignored. Transmission cooling and mount issues are secondary annoyances compared to the engine's potential for self-destruction.
AFM/DFM Lifter and Camshaft Failure Leading to Catastrophic Engine Damage
Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Lifter tick or clatter on cold starts that persists after warm-up, Check engine light with P0300-series misfire codes or P0521 oil pressure codes, Metal shavings in oil during changes, Sudden loss of power or complete engine failure if lifter collapses and drops valve
Fix: AFM lifters fail, chew up camshaft lobes, send metal through the oil system. Early catch means lifter/cam replacement (12-16 hours labor). If metal circulates, you're looking at rod bearings, main bearings, piston damage—full engine rebuild or short block replacement (25-35 hours). Some shops disable AFM preventively with Range/Pulsar device and tune.
Estimated cost: $3,500-6,000 for cam/lifters; $8,000-12,000+ for full rebuild or short block
Piston Ring Failure and Excessive Oil Consumption
Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Burning more than 1 quart per 1,000 miles, Blue smoke from exhaust on acceleration or startup, Fouled spark plugs causing misfires, Low oil pressure warnings if level drops critically between changes
Fix: The 3.6L can cook piston rings, especially if oil changes were stretched or AFM cycling accelerated wear. Requires engine teardown, new rings, honing cylinders, sometimes pistons themselves (20-28 hours). If cylinder walls are scored, you need an engine rebuild or replacement.
Estimated cost: $4,500-7,500 for rings and honing; $8,000-13,000 if full rebuild needed
Transmission Oil Cooler Line Leaks and Cooler Failure
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission fluid puddles under vehicle, usually passenger side, Pink or red fluid streaking down side of transmission case, Transmission overheating warnings on dash, Harsh shifts or slipping if fluid level drops significantly
Fix: Cooler lines corrode at crimp joints or cooler itself cracks from road debris. Replace lines and cooler as a set, flush system, refill (3-5 hours). Not hard, just annoying and messy. Catch it early before low fluid damages clutches.
Estimated cost: $600-1,200
Transmission Mount Failure (Torque Strut)
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking or thumping when shifting from Park to Drive or Reverse, Excessive engine/trans movement visible from engine bay during acceleration, Vibration through cabin at idle or low speeds
Fix: The upper torque strut mount (transmission side) separates or tears from age and load cycling. Very common on GM Lambda platform. Replace mount assembly (1.5-2.5 hours). Easy job, cheap insurance for driveline peace.
Estimated cost: $250-450
Timing Chain Stretch and Guide Wear
Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Rattling from front of engine on cold starts, subsides after 5-10 seconds, Check engine light with cam/crank correlation codes (P0008, P0016, P0017), Rough idle or hesitation, Sudden no-start if chain jumps timing
Fix: The 3.6L uses three chains (primary and two secondary). Guides wear, chains stretch, tensioners lose pressure. Full timing service means front cover off, all three chains, guides, tensioners, water pump while you're in there (14-18 hours). Do NOT ignore the rattle—jumped timing bends valves.
Estimated cost: $2,800-4,500
Water Pump Failure (Integrated with Timing Cover)
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Coolant weeping from timing cover area, Overheating or high temp warnings, Coolant smell from engine bay, Squealing or grinding from front of engine if bearing fails
Fix: Water pump is buried behind timing cover on the 3.6L. Same labor as timing chains (front cover removal, 10-14 hours standalone). Smart money says do pump + chains + guides together if you're over 100k and chains are getting noisy. Prevents paying twice.
Estimated cost: $1,800-3,200 standalone; add $600-800 to timing chain job
Owner tips
Use full synthetic oil (dexos1 Gen 2 spec) and change every 5,000 miles max—this engine NEEDS clean oil to survive AFM cycling.
Monitor oil level between changes; top off immediately if low. Starved lifters = dead engine.
Consider AFM/DFM disabler (Range device) with custom tune to eliminate cylinder deactivation wear—costs $500-800 but may save $10k engine rebuild.
Check transmission fluid color and level every 30k; service transmission at 60k even though GM says 'lifetime fluid'—this extends trans life significantly.
Listen for ANY unusual engine noise and investigate immediately—timing chains and lifters give warning before catastrophic failure, but the window is short.
Buy a 2022 if service records prove religious 5k oil changes and no engine noise present; otherwise the AFM time-bomb risk is real and expensive—budget $3k-5k contingency or walk away.

General Motors, LLC (GM) is recalling certain 2020-2022 Chevrolet Traverse and 2021-2022 Buick Enclave vehicles. The harness connector to the left or right side roof rail air bag may have incompatible electrical terminals, which could prevent the air bags from deploying in a crash.
Consequence: Roof rail air bags that do not deploy as intended increase the risk of injury in a crash.
Remedy: Dealers will replace the harness connector to the roof rail air bags, free of charge. Owner notification letters were mailed on April 29, 2022. Owners may contact Buick customer service at 1-800-521-7300 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N212352140.
