All 3 Known Issues
The 1st gen Traverse (2009-2017) uses the GM 3.6L V6 with the same endemic timing chain stretch issue affecting CTS, SRX, and other GM 3.6L vehicles. Three timing chains with plastic guides wear prematurely between 80,000-120,000 miles. This is one of the highest-volume 3.6L applications, making it extremely common. The chain-driven water pump also fails at similar mileage.
Common Symptoms
- Check engine light with P0008, P0009, P0016-P0019
- Engine rattle on cold start
- Rough idle or misfires
- Reduced engine power / limp mode
- Coolant leak (water pump failure)
How to Fix
Complete timing chain replacement with all three chains, guides, tensioners, and sprockets. Replace water pump simultaneously. Cloyes 9-0753S kit recommended. 10-14 hours labor.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
- UpgradeCloyes 9-0753S complete timing chain kit - all 3 chains, improved guides, tensioners, sprockets for GM 3.6L V6 (Cloyes #9-0753S)
- UpgradeAC Delco 251-749 water pump - chain-driven, replace during timing chain job (AC Delco #251-749)
- Note3.6L is interference engine - if chain jumps, valves hit pistons. Do not ignore cold-start rattle.
The 2nd gen Traverse (2018+) uses the GM 9T65 9-speed automatic which can exhibit harsh shifts, delayed engagement, and shudder. Similar to other GM 9-speed applications. GM has released multiple TCM calibration updates that significantly improve shift quality.
Common Symptoms
- Harsh or clunky shifts
- Delayed Park to Drive engagement
- Shudder at light throttle
- Hunting between gears
How to Fix
TCM recalibration at dealer with latest software. Fluid exchange with correct DEXRON HP fluid. Most issues resolve with software updates.
What Owners Are Using
Parts and tips from 0+ owners who fixed this issue
- TipThe 9T65 transmission is extremely sensitive to fluid condition. Use Dexron HP (ACDelco/GM 19354121) and change every 45,000 miles despite 'lifetime' claim. Fresh Dexron HP service resolved shift complaints that TCM calibration alone had not fixed. Pan drop with filter change recommended since 9T65 has no drain plug
- TipTSB 20-NA-136 documents 9T65 issues including 1-2 upshift slip/flare 5-15 mph. Current repair path: (1) latest TCM calibration, (2) if symptoms persist, inspect valve body for debris, (3) replace valve body and solenoid pack (OEM 24043134). Dealers sometimes skip to TCM-only - insist on full sequence
- NoteSudden loss of reverse reported due to missing check ball in valve body - a manufacturing defect. If Traverse loses reverse or any forward gear suddenly, stop driving immediately and have transmission inspected. Continuing to drive causes rapid hydraulic damage to clutch packs. Requires valve body replacement under warranty
The Traverse has one of the highest rates of AC compressor failure among midsize SUVs. Compressors seize or lose capacity often before 70,000 miles. When the compressor fails, it can send metal debris through the entire AC system, requiring replacement of the condenser, expansion valve, and system flush. Some owners report repeat failures within 8 months of repair.
Common Symptoms
- AC blows warm air
- Clicking or grinding noise from compressor
- AC works intermittently
- Compressor clutch not engaging
- Burning smell from AC system
