Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine 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.
The service bulletin advises the tech of a normal transmission shift condition and the delay in throttle response when the throttle plate is opened rapidly and advises the customer that it is normal for the delay.

The failure pattern owners describe
The 2020 Equinox engine complaints cluster around a pattern of sudden power loss and stalling, typically triggered by low oil pressure, PCV valve failure, vacuum pump seizure, or fuel system problems. Most striking: failures occur without warning lights in many cases, catching owners at highway speeds or traffic lights. One owner reports the same low oil pressure issue that spawned a class action suit against GM for 2017 and earlier models—yet the 2020 was excluded from that settlement despite identical symptoms.
Owners describe recurring check engine lights and "Reduced Engine Power" messages that ground the vehicle or force speeds below 30 mph. Two engine fires are documented, both from undetermined or under-hood origin with no prior warning. Water and coolant freeze in intercoolers in cold climates. Oil dipsticks slip out of position, dumping quarts onto hot engine components. Several owners faced catastrophic engine damage requiring $4,500 to $13,000 replacements as early as 25,000 miles.
Excessive oil consumption appears at 28,000 miles (1 quart per 1,000 miles), and fuel pump failures show up before 3,000 miles. Dealers sometimes blame bad fuel or cold weather for design flaws, and GM assistance programs appear inconsistent or insufficient. The troubling thread: owners maintain their vehicles on schedule, yet the engine still fails suddenly without mechanical warning.
