All 4 Known Issues
The GM Ecotec 2.4L direct-injection engine suffers from timing chain stretch and plastic guide breakage. GM received a bad batch of chains that were not properly hardened. The plastic guides break causing the chain to sag, and since this is an interference engine, failure can destroy the engine. The 2.4L also burns oil excessively due to improperly hardened piston rings (2010-2013), leading to low oil which accelerates timing chain wear.
Common Symptoms
- Rattling or pinging noise on cold start
- Check engine light with P0016 or P0017 codes
- Rough idle and loss of power
- Engine misfires
- Excessive oil consumption (related issue)
- Poor fuel economy
How to Fix
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.
Common Symptoms
- Excessive oil consumption (1qt per 2,000 miles)
- Check engine light with lean or misfire codes
- Rough idle, especially when cold
- Oil in intake manifold or intercooler
- Whistling noise from engine (vacuum leak)
How to Fix
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.

- UpgradeGM 12690058 updated valve cover assembly with integrated PCV - revised diaphragm design for 1.5T LFV/LYX (GM #12690058)
- TipAfter replacing the valve cover, check the intercooler for oil contamination - oil ingestion through the failed PCV can coat the intercooler
The 2008-2012 Malibu electric power steering system can suddenly lose assist, reverting to heavy manual steering. The EPS motor, controller, or steering column torque sensor fails. GM issued a special coverage program (10 years/150,000 miles) for this issue. When EPS fails, a warning message and chime sound, and the steering becomes very heavy at low speeds.
Common Symptoms
- Power Steering warning message on DIC
- Steering suddenly becomes very heavy
- Service ESC warning light
- Steering assist intermittent, especially in cold weather
- Steering wheel difficult to turn at parking speeds
How to Fix
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.
Common Symptoms
- Shudder at light throttle 25-50 mph
- Harsh 1-2 and 3-4 shifts
- Delayed engagement from Park to Drive
- Hunting between gears on hills
- Hesitation on acceleration
How to Fix
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.
