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
The 2016 Chevrolet Malibu's powertrain complaints cluster around several interconnected failures. The most dangerous and frequent is sudden loss of engine power at highway speeds—the car drops from 65+ mph to 20-40 mph without warning, triggering "Engine Power Reduced" warnings and immobilizing acceleration. Owners report this happens during interstate driving and uphill grades, leaving them stranded or creating collision hazards. Dealers attribute the issue to throttle position sensors or accelerator pedal sensors (~$520 repair), yet GM's own service bulletins acknowledge the problem.
Equally pervasive is the "Shift to Park" defect: the transmission's electronic shifter fails to recognize park position even when the lever is fully engaged. The vehicle won't shut off, stays in accessory mode draining the battery, and can't be locked. Jiggling the shifter or restarting helps temporarily, but the problem recurs. GM has issued service bulletins and one recall campaign (16V502000), but many affected vehicles fall outside recall scope. Repair costs run $450–$700 for shifter assembly replacement, and failures often recur within weeks.
Owners also report jerking transmissions from new, excessive engine movement under push-pull testing, stalling without warning, and brake pedal failures where pedals go rock-hard or travel to the floor with no pressure. Some owners describe replaced engines, transmissions, and shifters multiple times on the same vehicle. Dealers consistently tell owners problems are "working as designed" or deny replicating issues that happen intermittently, blocking warranty repairs after the basic coverage expires.

Shift to Park Warning / Park Position Not Recognized
Transmission shifter control fails to recognize when vehicle is in park position. Dash displays 'Shift to Park' or 'Action Required' warning even when shifter is fully in park. Vehicle will not shut off properly, remaining in accessory mode with lights and electronics active. Problem is intermittent initially, becoming frequent.
When: Problem occurs upon parking and attempting to shut off engine. Some owners report onset 2-3 years after purchase; others experience it early in ownership. Intermittent at first, then recurring regularly.
Symptoms owners cite: Shift to Park warning displays when vehicle is already in park; Vehicle will not fully shut off; remains in accessory/auxiliary mode; Interior and exterior lights remain on; Radio stays on; Vehicle cannot be locked; Repeated jiggling/manipulation of shifter needed to register park; Battery drain over time if vehicle left in this state; Horn may honk when exiting vehicle; Remote key detection fails
Codes mentioned: No error code stored in memory (noted in multiple complaints)
Repairs/costs cited: Shifter module/assembly replacement costs $450-$700. Harness replacement within shifter module attempted. Repairs fail after 6 weeks to 2 years. Multiple owners replaced shifter assembly multiple times with recurring failure.
Recalls/TSBs owners mention: GM acknowledges this as a 'known issue' per multiple dealers. Service bulletins and TSBs exist for this problem. NHTSA Campaign 16V502000 (Electrical System, Power Train) was issued but many vehicles with this issue are not included in recall VIN list. No official recall issued despite widespread complaints.
Excessive Powertrain Movement / Motor Mount Failure
Engine and powertrain move excessively when vehicle is pushed and pulled, and during gear shifts. Described as jolting, jerking, bucking sensation during downshifts. Appears to be related to degraded or faulty motor mounts allowing abnormal engine movement.
When: Present from early ownership. Some owners notice upon test drive before purchase; others develop after weeks/months of ownership.
Symptoms owners cite: Excessive engine movement when pushing/pulling parked vehicle; Firm/jolting sensation during shifts, especially downshifts; Engine RPM spikes during coasting or deceleration (1500 to 3000 rpm jump); Bucking sensation during braking and deceleration; Movement appears abnormal and outside industry standards per knowledgeable owners; Power train movement during shifts described as 'extreme'
Repairs/costs cited: No repairs documented in narratives. One owner planned to install dial indicator to measure movement.
Recalls/TSBs owners mention: Chevrolet has not provided investigation pathway. Dealers dismiss concerns, stating condition is 'working as designed.' Owner suspects systemic issue across multiple 2016 GM vehicles including Camaro.
Transmission Jerking / Abnormal Shifting Noise
Transmission exhibits jerking, bucking, and abnormal noises during normal operation. Vehicle may jerk abruptly when braking or shifting gears. Abnormal noise from transmission described as grinding or clanking. Occurs from 30 miles off the lot on some vehicles.
When: Occurs during normal city and highway driving. Can be present brand new (one owner reported at 30 miles). Worst in stop-and-go traffic.
Symptoms owners cite: Car bucks when braking from 3rd to 1st gear; RPM rises almost 1000 with each downshift; Engine pulls vehicle back abruptly; Transmission jerks and loses smooth operation; Abnormal loud noise from transmission; 100% occurrence in stop-and-go city driving; Occurs when brake is applied; Accelerated brake wear suspected
Repairs/costs cited: One owner had transmission replaced within 6 months of purchase but abnormal noise continued. Transmission replaced a second time with recurrence. No permanent fix found.
Recalls/TSBs owners mention: Dealers told one owner 'Chevy engines do that' and attributed to eco engine power conservation. Another dealer stated 'nothing wrong with your car' or 'working as designed.' No recalls issued despite multiple occurrences.
Engine Stall / Loss of All Power While Driving
Engine shuts off completely while driving at normal speeds with no warning. Vehicle loses all power, all dashboard warning lights illuminate. Does not restart immediately. Occurs intermittently, unpredictably.
When: Can occur at any time during normal driving. Some owners report weeks between incidents. Happens in traffic, on highways, at various speeds (30-70 mph).
Symptoms owners cite: Engine shuts off without warning while driving; All power lost; All dashboard warning lights come on; Stabilizer bar warning light illuminates; Check engine light illuminates; Takes extended time to restart or won't start initially; Incident recurs within same drive
Repairs/costs cited: Dealer diagnostic shows computer coming back 'clean' despite failures occurring. No resolution documented.
Recalls/TSBs owners mention: Dealers cannot determine cause. Computer diagnostics yield no codes despite failures. Owners suspect ECM or hybrid powertrain control module issue but no definitive fix identified.
Brake System Failure / Hard Brake Pedal
Brake pedal becomes extremely hard to depress with little to no pressure, or travels to floorboard without braking effect. Described as rock-hard, metal-on-metal grinding sound. Brake failure occurs without warning while driving.
When: Occurs intermittently without pattern. One owner reported first incident earlier in year, then reoccurrence.
Symptoms owners cite: Brake pedal rock hard, nearly impossible to depress; Brake pedal travel to floorboard without braking effect; Metal-on-metal grinding/clunking noise from brakes; No brake pressure; Brake lights fail to illuminate; Occurs at highway speeds without warning; Brakes return to normal after stopping
