This service bulletin provides information on some vehicles that may rock or move slightly forward or rearward while in Park at start up after cold soak. This condition may be accompanied by a clunk noise. This is a slight movement that is more often seen visually, rather than felt, when viewed from the outside and using the auto-start feature, if equipped.

What stands out
No new NHTSA powertrain complaint has been filed on this vehicle in over 10 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

The failure pattern owners describe
Owners of this 2009 Equinox describe a troubling progression of powertrain failures. Early on—around 43k miles—spark plug wires fail (GM issued a warranty notice). By 52k miles, the left front wheel bearing grinds and requires replacement.
The most alarming pattern centers on the StabiliTrak/traction control system. Multiple owners report the system triggers "SERVICE STABILITRAK," "TRACTION CONTROL OFF," and "ENGINE POWER REDUCED" warnings, often forcing the vehicle into limp-mode (5–25 mph). Some cases include temporary engine shutdown or no-start episodes. Dealers run diagnostics, clear codes (P0502, P0513, P0606, P0700), and report finding nothing wrong. The issue recurs. In one instance, an EGR valve and its wiring harness were replaced, yet the same warnings came back. Owners describe this as terrifying—losing power on the highway or losing brakes and traction control function unpredictably.
At 110k miles, the timing chain and guides fail, throwing codes P0008, P0018, P0017. One owner notes the 2009 Traverse uses the same 3.6L engine and was recalled for this exact issue; the Equinox was not. Transmission codes (P0752, P0700) appear alongside, suggesting the chain failure damaged the trans. Another owner reports the transmission gets stuck in second gear immediately after timing-chain service.
One report documents spontaneous acceleration at 129.7k miles. Another owner's airbag light has been on continuously since purchase. A third describes the engine continuing to run 10 minutes after shutdown.

Repairs/costs cited: One complaint reports transmission repair need immediately following timing chain replacement.
Spontaneous acceleration with StabiliTrak activation
Vehicle spontaneously accelerated while cruising at highway speed. Driver placed vehicle in neutral to regain control. StabiliTrak indicator illuminated.
When: 129,700 miles
Symptoms owners cite: Unintended forward acceleration; StabiliTrak indicator illumination

What owners are reporting 2 most recent
My 2009 Chevy equinox is slowing down when I reach 4 rpms and will not speed back up until I go back down to 3 rpms no matter how fast or slow I an going once it reaches 4 rpms it slows down. When I shut the car off something is still running under the hold because I can hear it. It was 10 minutes before it finally shut off completely.
My car stopped in the middle of the highway due to the computer system and my airbag light has been on since I bought the car.

Common questions
How serious is the powertrain problem on the 2009 Chevrolet Equinox?
It's a documented issue but not catastrophic. 10 complaints have been filed. Repairs average $2,500 and most owners catch it before it causes a breakdown.
At what mileage does the powertrain typically fail?
Across the 10 complaints that reported odometer mileage, most powertrain failures cluster between 71,627 and 129,700 miles, with the median around 110,000. A quarter of owners report trouble before 71,627; a quarter make it past 129,700. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to powertrain?
No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
