Chevrolet Malibu 2013–2015Common problems, reliability & repair costs

Symptoms: Check-engine and traction-control lights, then the car abruptly limits itself to roughly 30–50 mph — sometimes on the highway. Often intermittent, which makes it hard for dealers to reproduce.

Fix: GM recalled over 300,000 of these cars (15V-164) to reprogram the ECM, whose calibration could falsely trigger limp mode — that fix is free, so confirm it's done first. Cars that still act up after the reflash usually need an accelerator pedal position sensor or throttle body, a modest repair once correctly diagnosed. A class action alleged the pedal sensor as the root defect.

Symptoms: Hum or growl at highway speed that changes pitch when you weave gently in the lane; grows steadily louder. Owners commonly report replacing multiple bearings, and some corners fail more than once.

Fix: Hub/bearing assembly replacement — a bolt-in unit per corner, and one of the more DIY-friendly fixes on this car. GM addressed it in a service bulletin but never recalled it, so it's on you. Cost above is per corner at an independent shop; use quality (or AC Delco) hubs, since the cheapest replacements fail fast too.

Symptoms: Shudder on light acceleration, a bump or clunk on the 1-2 shift, delayed engagement into Drive, or flare/slipping into 2nd and 6th — often only once the transmission is warm. Worst case is outright failure.

Fix: GM service bulletins trace the 2-6 clutch flare to debris blocking oil passages in the valve body / channel plate — cleaning or replacing the valve body cures many cars at the low end of the range. A fluid service helps mild shudder. Cars that were never addressed can need a rebuilt or replacement transmission, which is the $3,000–$4,500 end. Shift quality on the test drive is your best screen.

Symptoms: Battery-drain warnings and a car that stalls or won't start; the recall condition could also produce burning smells, smoke, or fire in the trunk where the 115V lithium pack lives. Out-of-warranty packs simply die and immobilize the car.

Fix: The generator control module was recalled (13V-173) — dealers test and replace it free, so verify by VIN. The bigger exposure is the 115V lithium battery itself: owners report dealer quotes of $4,700–$5,000, with third-party rebuilders meaningfully cheaper. On a car worth $6k–$8k, that math is why we say buy an Eco only priced as if the battery is due.

Symptoms: Brake pedal suddenly goes hard and the car needs much more pedal force and distance to stop. Tied to the vacuum pump that provides brake boost on stop/start cars.

Fix: GM recalled 2014 Malibus with the 2.5L and stop/start (14V-247) for a brake-control-module software update that restores hydraulic boost assist when vacuum is lost — free, verify it's done. A later class action alleged the underlying vacuum pump itself degrades on 2013–2022 Malibus; a worn pump is a straightforward mechanical replacement at an independent shop.

Symptoms: Steering assist cuts out momentarily — sometimes alongside flickering electronics, radio, or lights — leaving the wheel suddenly heavy. Often intermittent and worse in cold weather, and dealers frequently can't replicate it.

Fix: The 2013 Malibu logged 176 NHTSA steering complaints; CarComplaints pegs the typical 'difficult steering' repair around $800 at 38k miles. Fixes range from an EPS module/software update to steering column or rack replacement depending on diagnosis. Because it travels with general electrical flakiness, have charging-system grounds and the 12V battery checked before throwing parts at the column.

Tools: Floor jack + jack stands, Socket set + breaker bar, Torque wrench, Large axle nut socket (front), Penetrating oil

1. Confirm which corner is bad: the hum gets louder loaded — swerve gently; if the noise drops when you steer away from a side, that side's bearing is suspect.
2. Jack and support the car, pull the wheel, and remove the brake caliper, bracket, and rotor (front: also the axle nut).
3. Unbolt the hub assembly from the knuckle — the bolts are usually rusted, so soak them first and use a breaker bar.
4. Clean the knuckle mating surface thoroughly; rust buildup here cocks the new hub and kills it early.
5. Bolt in the new hub assembly, torque everything to spec (axle nut torque matters — look it up for your year), and reassemble the brakes.
6. Road test: the hum should be gone immediately. If it's quieter but present, another corner is starting too.

Tools: Small screwdriver or trim tool (glovebox stops)

1. Open the glovebox and release the side stops so it swings down, exposing the cabin filter door.
2. Slide out the old cabin filter and insert the new one with the airflow arrow pointing the correct direction (marked on the housing).
3. For the engine filter, release the airbox clips, lift the lid, and swap the panel filter.
4. Re-clip the airbox and reset the glovebox stops.

Tools: Ratchet + spark plug socket (5/8"), Torque wrench, Extension bar, 10mm socket (coil bolts)

1. With the engine cold, remove the engine cover and unbolt/unplug the four ignition coils sitting over the plugs.
2. Blow or brush debris away from the plug wells so nothing falls into the cylinders.
3. Remove the old plugs with a spark plug socket and extension.
4. Gap-check the new iridium plugs (they come pre-gapped — just verify), thread them in by hand, then torque to spec. Do not overtighten into the aluminum head.
5. Reinstall coils and cover, then idle-test for smoothness.
