2010 Chevrolet Cobalt
Vehicle Specs & Maintenance Data
The 2010 Chevrolet Cobalt maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Chevrolet Cobalt.
For oil changes, the 2010 Chevrolet Cobalt takes 5W-30 motor oil with a capacity of 4.5 quarts. Brake fluid type is DOT 3, the recommended coolant is Dex-Cool (OAT), and transmission fluid is Dexron VI. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Chevrolet Cobalt, torque the lug nuts to 100 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.
Owners of the 2010 Chevrolet Cobalt have reported 5 common issues including "Ignition Switch Defect Causing Engine Shutoff", "Electric Power Steering (EPS) Failure" and "Timing Chain Tensioner and Guide Wear (2.2L Ecotec)".

Ignition Switch Defect Causing Engine Shutoff
The Cobalt's ignition switch can rotate out of the 'Run' position into 'Accessory' or 'Off' while driving, shutting off the engine and disabling power steering, power brakes, and airbags. A heavy keychain or knee bump to the ignition key can trigger the rotation. This defect was linked to at least 124 deaths and led to one of the largest recalls in automotive history.
NHTSA Recall 14V047000. GM recalled 2.6 million vehicles to replace the ignition switch with a redesigned unit that requires more force to rotate. The recall also included a reprogramming of the frontal airbag SDM. All repairs performed free of charge regardless of mileage or age.
Est. Cost: $0 (recall repair)Electric Power Steering (EPS) Failure
The electric power steering motor and its control module fail prematurely, causing a sudden complete loss of power assist while driving. The steering wheel becomes extremely heavy to turn and a 'Power Steering' warning message illuminates on the dash. This occurs without warning and is especially dangerous at low speeds during parking or turning maneuvers.
Replace the electric power steering motor and/or the power steering control module. GM issued TSB 09-02-35-001F addressing EPS motor failures. The EPS motor is mounted on the steering column and requires removal of the steering column covers to access. Flash the replacement module with the latest software calibration.
Est. Cost: $500 - $1,200Timing Chain Tensioner and Guide Wear (2.2L Ecotec)
The 2.2L Ecotec four-cylinder engine develops timing chain rattle, particularly on cold starts. The plastic timing chain guides and hydraulic tensioner wear prematurely, allowing the chain to slap against the guides. If not addressed, the chain can skip teeth, causing valve timing errors, misfires, and potentially catastrophic engine damage from piston-to-valve contact.
Replace the timing chain, tensioner, and all chain guides. The updated GM tensioner has improved oil flow passages. This requires removing the front engine cover. Also inspect the crankshaft and camshaft sprockets for wear and replace if the teeth are hooked or worn unevenly.
Est. Cost: $500 - $1,200Fuel Pump and Fuel Gauge Failure
The fuel pump module and fuel level sender fail, causing inaccurate fuel gauge readings, stalling, hard starting, and in some cases complete fuel pump failure leaving the vehicle stranded. Owners commonly report the fuel gauge dropping to empty or reading erratically while the tank still has fuel, making it impossible to judge remaining range.
Replace the in-tank fuel pump module, which includes the fuel level sender. The entire pump module must be accessed by dropping the fuel tank. Replace the fuel filter at the same time. Use a genuine AC Delco pump module for reliability.
Est. Cost: $400 - $800Front Suspension Lower Control Arm Bushing Deterioration
The front lower control arm bushings wear out prematurely, causing clunking noises over bumps, imprecise steering, and uneven tire wear. The rubber bushings crack and separate from their metal housings, allowing excessive movement. This issue is accelerated by rough road conditions and affects steering stability and alignment.
Replace both front lower control arms, as the bushings are pressed in and not easily replaceable separately. Perform a four-wheel alignment after replacement. Inspect tie rod ends and sway bar links at the same time, as they often wear concurrently.
Est. Cost: $300 - $700
