Reliability report · 2020 Chevrolet Malibu · Updated July 2026 · ~$1,950/yr fuel · what it costs to keep →

A settled 1.5T sedan — most of what's left are software reflashes, not broken engines.

By 2020 the Malibu is the refreshed, 1.5-liter-turbo-only sedan, and the data reads settled. Complaints hold at 190, and the standout items are software rather than mechanical: GM issued a service update for a cam-phaser false diagnostic code that can trip the malfunction lamp and a reduction of power, an engine-control-module reflash for erroneous fuel enrichment, and a Customer Satisfaction Program to re-secure the transmission oil-cooler lines to the fan shroud.

The only federal safety recall is the 2016–2021 rear-seat-belt-retractor campaign. The early-Malibu vacuum-pump and reduced-power tells still deserve a test drive, but on 2020 they're checks, not expected failures. Confirm the seat-belt recall, ask whether the transmission-line program and the software updates were applied, and this is a sound, cheap used sedan — with the fleet-car caveat that many were hard-used rentals.

Canary status

Chirping

What that means: The 2020 holds at 190 complaints with a single safety recall (seat belts). The reduced-power hardware from the early years is largely resolved, and much of what remains is dealer software — a cam-phaser false-code reflash, an engine-control fuel-enrichment update, and a program to re-secure the transmission oil-cooler lines.

Cam-phaser false code — reduced power, fixed by reflash

moderate
  • 1.5L turbo I4

GM issued a service update for 2020 Malibus where the exhaust cam phaser doesn't fully park, setting a false diagnostic trouble code that can light the malfunction-indicator lamp and cause a reduction of power. The fix is a free engine-control-module reprogram — no hardware. If a 2020 shows an intermittent reduced-power message or check-engine light, this reflash is the first thing to ask about rather than assuming a mechanical failure.

This is a 1.5L turbo I4 problem. The 2.0L turbo I4 and Hybrid (eCVT) don’t share it.

Transmission oil-cooler lines not secured (CSP)moderate

A Customer Satisfaction Program (a CSP, GM's quiet coverage) covers 2020 Malibus whose transmission oil-cooler lines were not properly secured to the fan shroud; dealers inspect the connection, secure it, and replace the lines if they show signs of leaking. Because a loose or seeping transmission line is easy to miss on a used car, confirm this program was performed and check under the front of the car for fluid.

Rear seat-belt retractors — recall 21V-649moderate

The 2020's one federal safety recall: 21V-649 covers 2016–2021 Malibus whose rear seat-belt retractors may be improperly secured with loose or missing fasteners, potentially failing to restrain an occupant in a crash. Dealers inspect and tighten them free. The belts feel normal day to day, so verify the recall is closed by VIN.

Engine-control fuel-enrichment reflash and carryover tellsminor

GM also issued a service update for engine-control-module software that could add erroneous fuel enrichment under rare driving conditions, resolved by a reprogram. Beyond the software, the early-Malibu vacuum-pump hard-pedal pattern (code P1101) and the GM 'Shift to Park' false message can still appear but are far quieter here. Treat them as test-drive checks: firm-but-boosted brake feel, and a car that correctly recognizes park.

Before you buy

Print this
  1. 01Confirm recall 21V-649 (rear seat-belt retractors) is closed by VIN.
  2. 02Ask whether the transmission oil-cooler-line CSP was performed, and look under the front of the car for fluid.
  3. 03If a reduced-power message or check-engine light appears, ask about the cam-phaser and fuel-enrichment software updates before assuming a mechanical fault.
  4. 04Test-drive for a hard brake pedal (vacuum-pump check) and shift-to-park behavior — quieter on 2020, but still the known tells.
  5. 05Because many 2020s are ex-fleet rentals, pull full service history and confirm oil changes weren't stretched on the turbo engine.
