On the 2013-2024 Chevrolet Malibu, the 2013+ Malibu uses an electric power steering (EPS) system with a column-mounted motor that is prone to failure. The motor develops internal faults causing intermittent or complete loss of power steering assist, making the car extremely difficult to steer at low speeds. GM issued TSB 18-NA-205 and NHTSA investigated numerous complaints. The steering column module and torque sensor can also fail, triggering a "Service Power Steering" message on the DIC.
Have the EPS motor and torque sensor diagnosed with a scan tool — the module stores specific fault codes. Replacement of the EPS motor assembly costs $400-$800 for parts and $200-$400 for labor. In some cases, a software recalibration of the EPS module resolves intermittent faults. Check for applicable GM TSBs, as some vehicles may qualify for extended warranty coverage. Never ignore a power steering warning — sudden loss of assist at highway speed is a safety hazard.

On the 2016-2024 Chevrolet Malibu, the 1.5L turbocharged engine in 2016+ Malibu has a PCV system integrated into the valve cover that commonly fails, causing excessive oil consumption, rough idle, and check engine lights. The PCV diaphragm ruptures, creating a vacuum leak and allowing oil to be ingested into the intake. This is the same engine family as the Equinox 1.5T. GM has released an updated valve cover design.
Replace valve cover assembly which includes the integrated PCV system. GM updated design is less prone to failure. Check for oil contamination in the intercooler and intake - clean if found.

On the 2013-2020 Chevrolet Malibu 2.5L Ecotec, the 2.5L Ecotec 4-cylinder engine in the 2013-2020 Malibu consumes oil at a rate well beyond what GM considers normal, with some owners reporting 1 quart every 1,500-2,000 miles. The piston rings do not properly seat against the cylinder walls, allowing oil to pass into the combustion chamber. The issue is exacerbated by the use of 0W-20 oil specified by GM. There is no visible external leak — the oil is burned internally and exits through the exhaust.
Monitor oil level at every fuel stop and top off as needed with 0W-20 or 5W-30 synthetic oil. GM considers up to 1 quart per 2,000 miles "acceptable," but an oil consumption test at the dealer can document excessive use for warranty claims. For out-of-warranty vehicles, switching to a slightly heavier 5W-30 oil can reduce consumption. Severe cases require piston ring replacement ($2,000-$3,500). An Italian tune-up (sustained highway driving at higher RPM) can temporarily help by burning carbon off the rings.

On the 2016-2024 Chevrolet Malibu, the 2016+ Malibu with the 1.5T engine uses a GM/Ford co-developed 9-speed automatic (9T50) that can exhibit shudder, harsh shifts, and delayed engagement. The 9-speed is sensitive to fluid condition and requires proper DEXRON HP fluid. GM has released multiple TCM calibration updates. The 2.0T Malibu uses a different 9-speed (9T65) with similar but less frequent issues.
TCM software update at dealer is first step. Fluid exchange with Mobil 1 LV ATF HP can improve shift quality. For persistent shudder, valve body replacement may be needed.

On the 2008-2020 Chevrolet Malibu, the A/C compressor clutch on the Malibu fails due to a burned-out clutch coil, worn clutch plate, or bearing failure in the compressor pulley. When the clutch fails, the A/C blows warm air because the compressor cannot engage. A squealing or grinding noise from the serpentine belt area is common before total failure. The compressor clutch can also seize, which will shred the serpentine belt and cause a loss of all belt-driven accessories (alternator, power steering, water pump).
On some models, the A/C clutch assembly can be replaced independently ($100-$200 for parts, $200-$400 labor) without replacing the entire compressor. If the compressor itself has failed internally (metallic debris in the system), the entire compressor must be replaced along with the receiver/drier, expansion valve, and a system flush ($800-$1,500 total). Always evacuate and recharge the system with the correct amount of R-134a refrigerant after any compressor work.

On the 2008-2024 Chevrolet Malibu, the trunk latch mechanism on the Malibu fails due to a worn release cable, broken latch spring, or faulty trunk release actuator motor. Owners report the trunk will not open via the key fob, interior button, or the trunk release button on the lid. In some cases, the trunk will not latch closed and pops open while driving. Water intrusion into the latch mechanism accelerates corrosion and failure, especially in northern salt-belt states.
Replace the trunk latch assembly ($50-$150 for the part) and inspect the release cable for fraying or binding. Labor is typically 1-2 hours ($100-$200). If the trunk will not open at all, access the latch through the rear seat pass-through (fold down the center armrest) and manually release it. Lubricate the latch mechanism with white lithium grease after replacement to prevent future corrosion. Check the trunk seal for damage that may be allowing water into the latch area.
