What is the 2008-2013 Chevrolet Malibu Ecotec 2.4L Timing Chain and Guide Failure?
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 des… Repairs typically run $1,000-$3,000. Severity: high.
What is the 2008-2012 Chevrolet Malibu Electric Power Steering (EPS) Assist Motor Failure?
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 war… Repairs typically run $800-$1,600. Severity: high.
What is the 2008-2020 Chevrolet Malibu A/C Compressor Clutch Failure?
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 bel… Repairs typically run $200-$1,500. Severity: medium.
What is the 2008-2019 Chevrolet Malibu P0420 — Catalyst Efficiency Below Threshold (Bank 1) from Oil-Consumption-Poisoned Converter on the 2.4L Ecotec?
The single most common P0420 pattern on the Malibu is on the 2008-2012 2.4L Ecotec (LE5/LE9), whose low-tension piston rings are notorious for excessive oil consumption. Burned oil sends phosphorus and other contaminants into the exhaust, which glazes and poisons the catalytic co… Repairs typically run $700-$2,400. Severity: medium.
What is the 2004-2012 Chevrolet Malibu P0430 — Catalyst Efficiency Below Threshold (Bank 2) from Aged/Failed Rear-Bank Converter on the V6?
Like P0174, P0430 only applies to the V6 Malibus (3.5L 2004-2007, 3.6L 2008-2012) because it monitors the converter on Bank 2 — the rear/opposite bank from cylinder 1. On these V6s the code is almost always a worn-out rear-bank three-way catalytic converter that can no longer sto… Repairs typically run $600-$1,800. Severity: medium.
What is the 2004-2012 Chevrolet Malibu P0174 — System Too Lean (Bank 2) from Failed EVAP Purge Valve / Intake Manifold Gasket Leak on the 3.5L & 3.6L V6?
P0174 (lean, Bank 2) only sets on the V6 Malibus (3.5L LX9 in 2004-2007 and 3.6L LY7/LLT in 2008-2012), since the four-cylinder Malibus have only one bank. On these V6s the classic trigger is unmetered air reaching the cylinders on the bank opposite cylinder 1: a stuck-open or le… Repairs typically run $150-$600. Severity: medium.
What is the 2004-2015 Chevrolet Malibu P0302 — Cylinder 2 Misfire from Failed Ignition Coil or Fouled Spark Plug?
P0302 on the Malibu is most often a failing ignition coil or a worn/fouled spark plug at cylinder 2. On the four-cylinder Ecotec engines (2.2L, 2.4L, 2.5L) each cylinder has its own coil, so when the #2 coil weakens it can no longer produce a strong enough spark and that cylinder… Repairs typically run $100-$350. Severity: medium.
What is the 2008-2024 Chevrolet Malibu Trunk Latch and Release Failure?
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 no… Repairs typically run $50-$350. Severity: low.
What is the 2008-2019 Chevrolet Malibu P0128 — Coolant Below Thermostat Regulating Temperature from Thermostat Stuck Open?
On the Malibu, especially the 2008-2012 2.4L Ecotec, P0128 is overwhelmingly caused by the engine thermostat sticking open. These thermostats fail as their internal rubber seal deteriorates, so coolant flows through the radiator constantly and the engine never reaches the calibra… Repairs typically run $150-$350. Severity: low.
