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 2017 Malibu's engine exhibits a dominant and recurring failure pattern: sudden loss of power while driving, with the "Engine Power Reduced" warning message and check engine light appearing on the dash. Owners report this happens on highways and city streets at any speed, abruptly limiting the vehicle to 20–30 mph regardless of pedal input. Restarting the engine temporarily clears the symptom, but it returns days or hours later. Dealerships are unable to replicate or diagnose the fault during service visits, and owners have cycled through multiple failed repairs—throttle sensor replacement, oxygen sensor swaps, accelerator pedal replacements (some owners had three pedal units swapped in two months), and software updates—with no permanent resolution.
Owners also report engine stalls, sometimes during intersections or traffic, and internal engine damage. Several describe cracked or damaged pistons and one details a burst camshaft spreading metal throughout the engine. A car rental employee notes that after piston replacement, the pistons cracked again within 12,000 miles, suggesting the root cause was never addressed. One owner experienced unintended acceleration in reverse, striking two parked vehicles.
A pre-ignition recall exists, but one owner claims the dealership's fix did not match GM's official service bulletin and did not cover the cost as promised. The accelerator pedal position sensor has been on national back order. Owners are frustrated that no recall addresses the engine power reduction issue despite repeated online complaints and significant safety concerns on highways.

Failure modes owners describe
Engine Power Reduced / Limp Mode
Vehicle enters reduced power mode, limiting speed to 20-30 mph. Check engine light and 'Engine Power Reduced' warning message appear on instrument panel. Issue typically occurs while driving at various speeds or highways. Turning engine off and restarting temporarily resolves the symptom, though it recurs. Dealers frequently cannot replicate or diagnose the fault during service visits. Causes cited include throttle position sensor issues, accelerator pedal sensor problems, oxygen sensor faults, and computer code malfunctions, but no single root cause has been consistently identified or fixed across complaints.
When: 20,000–96,400 miles; occurs within first few years of ownership
Symptoms owners cite: Check engine light illuminates; Engine Power Reduced warning message displayed; Vehicle speed limited to 20–30 mph; Reduced acceleration regardless of pedal input; Traction control warning light may illuminate; Condition temporary; restart clears symptom; Recurs intermittently or frequently (multiple times per week to multiple times per day)
