The most documented Chevrolet Traverse problem is timing chain elongation in the 3.6L LLT V6, covered by GM bulletin 12-06-01-009 for 2009-2012 models. Watch for a 2-5 second cold-start rattle and codes P0008, P0009 or P0016-P0019. A chain repair typically costs $1,800-$3,500; check open recalls 14V-118 and 14V-266 too.
- GM bulletin 12-06-01-009 lists the 2009-2012 Traverse (3.6L LLT V6) for timing chain repairs when codes P0008, P0009 or P0016-P0019 set.
- A 2-5 second rattle after a cold start plus correlation codes on both banks points strongly at the chain, not a sensor.
- 2009 models are covered for a cracked 3-5-reverse wave plate for 10 years or 120,000 miles under special coverage 14404B.
- Recalls 14V-118 (side airbag connectors) and 14V-266 (front seat belt cable) cover first-generation models and are free.

What Are the Most Common Chevrolet Traverse Problems?
The most common Chevrolet Traverse problems depend on the generation. On the 2009-2017 first generation, the documented weak spot is timing chain elongation in the 3.6L LLT V6, which GM addressed in service bulletin 12-06-01-009 for 2009-2012 models. Transmission faults, two large safety recalls and, on 2018-2019 models, nine-speed shift complaints follow.
| What you notice | Model years | Most likely issue |
|---|---|---|
| Rattle for 2-5 seconds after a cold start, check engine light | 2009-2017 (bulletin lists 2009-2012) | Timing chain elongation, codes P0008/P0009/P0016-P0019 |
| No reverse, or slips/flares into 3rd and 5th gear | 2009 | Cracked 3-5-reverse clutch wave plate (special coverage) |
| “SERVICE AIR BAG” message, airbag light on | 2009-2013 | Seat-mounted side airbag connector (recall 14V-118) |
| Front seat belt feels loose or the lap anchor looks frayed | 2009-2014 | Seat belt anchor cable (recall 14V-266) |
| Light shudder during shifts below 40 mph | 2018 | Torque converter clutch shudder, 9T65 nine-speed |
| Stuck in 1st or reverse, will not go above 25 mph | 2019 | 9T65 control fault with code P2731 stored |
Which Engine Does Your Traverse Have?
Knowing which engine your Traverse has matters, because the well-known chain problem belongs to one engine. Every 2009-2017 Traverse uses the 3.6L LLT direct-injection V6 (281-288 hp) with a six-speed 6T75 automatic. The older LY7 3.6L was never fitted to the Traverse.
| Generation | Engine | Transmission | Issue to know about |
|---|---|---|---|
| 2009-2017 | 3.6L V6 LLT | 6-speed 6T75 | Timing chain elongation; 2009 wave plate |
| 2018-2023 | 3.6L V6 LFY (2.0L turbo LTG on some RS models) | 9-speed 9T65 | Low-speed shudder (2018), P2731 no-upshift (2019) |
| 2024 on | 2.5L turbo four-cylinder (328 hp) | 8-speed | Too new for a clear pattern |
The engine code (LLT or LFY) is on the RPO sticker in the glovebox.
Why Does the 2009-2012 Traverse Stretch Its Timing Chain?
The 2009-2012 Traverse timing chain problem is wear in the chain itself: the pins and links wear, the chain grows slightly longer and the camshafts fall behind the crankshaft. GM bulletin 12-06-01-009 lists the 2009-2012 Traverse (engine RPO LLT) and released updated timing chain and guide kits for this repair.
The V6 runs one primary and two secondary chains, so small wear in each adds up. Technicians widely link the wear to oil condition: long change intervals, a low oil level and oil that does not meet GM’s specification all speed it up. GM introduced its dexos1 oil specification for 2011 model-year gasoline engines, after the first Traverses were built.
There is no safety recall for the chain: wear is a durability fault, so GM handled it through the bulletin, which is repair guidance rather than free coverage.
What Are the Symptoms of a Stretched Traverse Timing Chain?
A stretched Traverse timing chain usually announces itself with a short rattle from the front of the engine for two to five seconds after a cold start, then a check engine light with one or more correlation codes. The rattle fades once oil pressure builds and the tensioners take up the slack.
Later signs are rough idle and reduced power. The bulletin’s codes are generic SAE J2012 codes:
| Code | Generic meaning | On the Traverse 3.6L |
|---|---|---|
| P0008 | Engine Position System Performance, Bank 1 | Bank 1 cams out of step with the crank, typically chain wear |
| P0009 | Engine Position System Performance, Bank 2 | Same check on the other cylinder bank |
| P0016 / P0017 | Crankshaft-Camshaft Position Correlation, Bank 1 Sensor A / B | Intake (A) or exhaust (B) cam on bank 1 |
| P0018 / P0019 | Crankshaft-Camshaft Position Correlation, Bank 2 Sensor A / B | Intake (A) or exhaust (B) cam on bank 2 |
One correlation code alone can be a sensor, a wiring fault or a sticking cam phaser solenoid; our P0016 code guide walks through those checks. Several correlation codes across both banks, plus a cold-start rattle, point strongly at the chain. A sticking phaser more often sets P0011 instead. A steady tick that does not fade with warm-up is a different noise; see engine ticking noise.
What Transmission Problems Does the Traverse Have?
Traverse transmission problems differ by generation. On the 2009 model, GM’s special coverage 14404B covers a cracked 3-5-reverse clutch wave plate in the 6T75 that causes loss of 3rd, 5th and reverse gears, for 10 years or 120,000 miles from first use, regardless of owner.
For the 2018 model with the nine-speed 9T65, GM preliminary information PIP5546C describes a slight shudder during shifts at 40 mph or below, traced to the torque converter clutch and treated with a fluid drain and fill. Bulletin 18-NA-379 covers 2019 models stuck in 1st or reverse, unable to exceed 25 mph, with code P2731 stored.
Which Safety Recalls Affect the First-Generation Traverse?
Two large recalls cover the first-generation Traverse, both free at a dealer. Recall 14V-118 covers the seat-mounted side airbag connectors on some 2009 and all 2010-2013 models: corrosion or loose crimps raise resistance, light the airbag lamp and can stop the side airbags and pretensioners deploying.
The fix splices and solders the wires in place of the connectors. Recall 14V-266 covers the flexible steel cable that anchors the front outboard seat belts on 2009-2014 models, which can fatigue and separate. If the airbag light is on, enter your VIN on NHTSA’s recall lookup before anything else.
How Is the Traverse Different From the Equinox, Terrain and Silverado?
The Traverse, Equinox, Terrain and Silverado share a badge family but not the same weak spots. The Traverse’s documented problem is 3.6L V6 chain elongation; the 2018-on Equinox and Terrain use a 1.5L turbo four-cylinder, and the Silverado’s best-known issue is V8 lifter failure tied to cylinder deactivation.
| Model | Engine covered in our guide | Main documented issue |
|---|---|---|
| Traverse 2009-2017 | 3.6L V6 LLT | Timing chain elongation |
| Equinox | 1.5L turbo four-cylinder | Oil consumption, chain wear |
| GMC Terrain | 1.5L turbo four-cylinder | Chain wear, cold-start rattle |
| Silverado | 5.3L / 6.2L V8 | AFM/DFM lifter tick |
Note that 2010-2012 Equinox and Terrain V6 models also appear in GM’s chain bulletin.
How Do You Check a Traverse for These Problems?
Checking a used Traverse for these problems takes about 30 minutes and costs little. Start the engine after it has sat overnight, listen at the front, then scan for stored and pending codes.
- Cold start: a rattle that lasts 2-5 seconds and fades is the classic chain warning. Other causes are in our cold-start rattle guide.
- Codes: look for P0008, P0009 and P0016-P0019, including pending ones.
- Oil: check the dipstick and ask for service records; long gaps are a warning sign.
- Transmission: try reverse and every gear; on 2018-2019, feel for shudder below 40 mph.
- Recalls: run the VIN through NHTSA’s lookup for 14V-118, 14V-266 and anything newer.
What Does It Cost to Fix Common Traverse Problems?
The cost to fix common Traverse problems runs from nothing for recall work to several thousand dollars for a timing chain replacement. The chain job is labour-heavy: the front cover comes off and three chains, guides and tensioners are replaced together.
| Repair | What is done | Typical US cost, October 2026 |
|---|---|---|
| Recalls 14V-118, 14V-266 | Connector splice; belt anchor repair | $0 at a dealer |
| Code scan and diagnosis | Scan, cam/crank data check | $100-$200 |
| Timing chain set, 3.6L V6 | Primary and secondary chains, guides, tensioners | $1,800-$3,500 |
| 9T65 shudder | Software update, fluid drain and fill | $150-$400 out of warranty |
| Transmission replacement | Rebuilt or new unit | $3,500-$6,000 |
What does not work: a thicker oil or an additive to quiet the rattle, or replacing a cam sensor because the code names one, when several codes and a rattle are present.
Can You Keep Driving a Traverse With a Stretched Chain?
You can keep driving a Traverse with an early chain rattle for a short time, but not indefinitely. Correlation codes mean the wear is already measurable, and if a worn chain jumps a tooth or breaks, the valves can hit the pistons and the repair becomes an engine replacement.
Until the repair, check the oil level every fill-up, use oil that meets dexos1 and do not stretch change intervals. See our oil change interval guide. More in our car brands section.
Short term only with an early cold-start rattle and correlation codes: check oil every fill-up and book the repair. Stop driving if the rattle becomes constant, the engine runs roughly or the check engine light flashes.
See a Chevrolet dealer or a qualified shop if the airbag light or a “SERVICE AIR BAG” message appears, if a front seat belt feels loose, if the transmission loses reverse or will not upshift, or if a rattle lasts beyond a few seconds after start-up. Timing chain replacement on the 3.6L V6 needs cam-locking tools and exact timing marks; it is beyond a driveway job. Never probe or unplug airbag wiring under the seats yourself.
Frequently Asked Questions
What years of Chevrolet Traverse have timing chain problems?
GM’s bulletin 12-06-01-009 lists the 2009-2012 Traverse with the 3.6L LLT V6. The 2013-2017 models keep the same engine family, so the same symptoms and codes are worth watching for. The 2018-on LFY V6 and the 2024-on 2.5L turbo are not part of that bulletin.
Does the Chevrolet Traverse have a timing belt or a timing chain?
Every Chevrolet Traverse uses timing chains, not a belt. The 3.6L V6 has one primary chain and two secondary chains, and there is no fixed replacement interval. Chains are meant to last the life of the engine, so a cold-start rattle or correlation codes signal a fault rather than due maintenance.
How long does a Traverse timing chain last?
A Chevrolet Traverse timing chain has no replacement interval and is designed to last the life of the engine. On 2009-2012 engines, wear can show up much earlier, especially where oil changes were stretched or the oil level ran low between services, which is why GM issued its chain bulletin.
Is the 2009 Chevrolet Traverse a reliable used buy?
A 2009 Chevrolet Traverse can be a sound used buy only with proof of regular oil changes, completed recalls and a clean cold start. It carries the chain bulletin, the wave plate special coverage and both recalls, so service records matter more than mileage. Budget for a chain repair if records are missing.
Which Chevrolet Traverse years are best?
Later first-generation years (2013-2017) avoid the 2009 wave plate issue and are not listed in GM’s chain bulletin, though the engine family is the same. Among the second generation, 2020-2023 models came after the bulletins for early nine-speed shudder and no-upshift faults. Condition and records still outweigh model year.
Can low oil cause a Traverse timing chain to stretch?
Low or degraded oil is widely linked to faster chain wear on the Chevrolet Traverse 3.6L V6. The chain, guides and tensioners rely on clean pressurised oil, and direct injection dilutes oil with fuel and soot. Checking the level every fill-up and using dexos1 oil are the cheapest protection.
Is the Traverse timing chain covered by warranty?
The Chevrolet Traverse timing chain is covered under the original powertrain warranty, which has expired on 2009-2017 models. There is no recall for it. A dealer can check your VIN for any campaign or goodwill history, and good service records help if you ask for assistance.
