Owners have filed 34 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA powertrain complaint has been filed on this vehicle in over 6 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.
This bulletin provides information on identifying Non-GM Engine Calibrations for Gasoline Engines using the Tech 2 or GDS 2.

The failure pattern owners describe
Owners of the 2020 Chevrolet Equinox report a range of powertrain failures across multiple systems. Many describe sudden loss of engine power while driving — the vehicle either shuts off completely, stalls unexpectedly, or loses power mid-acceleration with no warning lights. Several owners report delayed or weak acceleration response, with 2–3 second lags or outright refusal to accelerate despite pressing the pedal fully. Transmission problems surface frequently: jerking, shaking, and shuddering during acceleration starting around 35–40 mph; failed torque converters; and transmission fluid leaks, some discovered within 500 miles of purchase.
Fuel-system issues include sputtering, vibration, and popping sounds after refueling, along with fuel pump failures and fuel injector problems. Some owners report water intrusion into the cabin and rear wheel wells correlating with stalling episodes. A vacuum booster pump is reported to have exploded catastrophically in at least one case. Electrical glitches tied to rain exposure cause gauges to fluctuate and false warning messages to cascade, making braking difficult. One owner reports the vehicle rolling backward on a slight incline without the emergency brake engaged. Several owners note that dealerships fail to duplicate issues or find causes, leaving problems unresolved. GM has acknowledged some transmission vibration issues to dealers but offers no fix.

What owners are reporting 2 most recent
My 2020 equinox has less than 500 miles and over the weekend, when coming to a stop at a light, the forward completely disengaged and would not allow us to move forward. We could only go reverse. We had our 5 year old grandson with us and this was terrifying. It could have been even more dangerous had it been dark or on a busier road.
Forward collision system dint notify of an object infront , also breaks locked up when used .Air bags didn’t go off while a forward collision with a bus happened
Common questions
How serious is the powertrain problem on the 2020 Chevrolet Equinox?
It's a meaningful issue. 34 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $2,500.
At what mileage does the powertrain typically fail?
Across the 10 complaints that reported odometer mileage, most powertrain failures cluster between 3,800 and 72,000 miles, with the median around 60,000. A quarter of owners report trouble before 3,800; a quarter make it past 72,000. 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.
