The 2010 Cobalt is a simple economy car with two major recurring failures: catastrophic ignition switch problems (recall-related) that can disable the vehicle mid-drive, and electric power steering column failures that leave you with no assist. The 2.2L is more durable than the 2.4L, which sees frequent timing chain and internal engine damage.
Ignition Switch Failure (Recall-Related)
Common · high severity
Symptoms: Engine shuts off while driving, Key rotates out of RUN position on bumpy roads, Loss of power steering and brakes while moving, Airbags disabled (warning light), No-crank condition
Fix: Replace ignition switch and lock cylinder assembly. This was subject to massive GM recall 14V-047, but many vehicles still have original defective parts if owners never completed recall work. 1.5-2.0 hours labor including re-key if needed.
Estimated cost: $150-350
Electric Power Steering Column Failure
Common · high severity
Typical onset: 60,000-110,000 mi
Symptoms: Sudden loss of power steering assist, SERVICE STABILITRAK and steering wheel warning lights, Grinding or clicking noise from column when turning, Intermittent assist that cuts in/out
Fix: Replace entire steering column assembly or internal torque sensor/motor unit depending on failure mode. This is a known weak point on all Cobalts. GM issued TSB and recall campaigns (14V-153, 10V-017). 3.0-4.5 hours labor for column replacement.
Estimated cost: $600-1,200
2.4L Ecotec Timing Chain Stretch and Engine Failure
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Cold-start rattle for 2-3 seconds, Check engine light with cam/crank correlation codes (P0017, P0014), Poor fuel economy and rough idle, Catastrophic engine failure if chain jumps timing
Fix: Timing chain, guides, tensioner, and both VVT solenoids. If caught early, 8-10 hours labor. If chain jumped and bent valves, you're looking at head work or short block replacement. The 2.4L has inadequate oil flow to the timing system; religious 5,000-mile oil changes are critical. This engine grenades itself more often than the 2.2L.
Estimated cost: $1,200-2,000 preventive / $3,500-5,500 after internal damage
Automatic Transmission Fluid Cooler Line Leaks
Occasional · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Transmission fluid pooling under vehicle near radiator, Low fluid level causing harsh shifts or slipping, Pink fluid residue on radiator or frame rails
Fix: Replace cooler lines (they rust through at crimp fittings) and top off fluid. If driven low on fluid, the 4T45-E transmission will burn clutches and require rebuild. 1.5-2.0 hours labor for lines only.
Estimated cost: $250-450
Front Engine Mount (Transmission Mount) Collapse
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Excessive engine movement during acceleration or shifting, Clunking noise when putting into gear, Vibration at idle, Visible separation or tearing of rubber mount
Fix: Replace front transaxle mount (often called transmission mount). This is a hydraulic-damped mount that fatigues and fails. 1.5 hours labor, must support engine from above.
Estimated cost: $200-350
Fuel Pump Module Failure
Occasional · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: No-start with cranking but no fuel pressure, Intermittent stalling when fuel tank below 1/4, Whining noise from rear of vehicle, Check engine light with fuel trim codes
Fix: Replace fuel pump module assembly in tank. Common on these when original pump wears out. 2.0-2.5 hours labor to drop tank or access via rear seat removal method if sedan.
Estimated cost: $400-700
Window Regulator Failure (Front Doors)
Occasional · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Window drops into door suddenly, Grinding or clicking when operating window, Window off-track or tilted in channel, Slow window operation
Fix: Replace window regulator assembly. Plastic rollers and cables fail. 1.5-2.0 hours per door including door panel removal.
Estimated cost: $250-450 per door
Owner tips
If you have the 2.4L engine, change oil every 5,000 miles maximum with quality synthetic — timing chain life depends on it
Complete the ignition switch recall immediately if not already done; this is a genuine safety hazard
Check power steering column operation regularly; if you hear any clicking or grinding from the column, address it before it fails completely
Inspect transmission cooler lines annually for rust and seepage, especially in rust-belt states
The 2.2L Ecotec is significantly more reliable than the 2.4L — prioritize that engine if shopping
Buy only if it's a 2.2L with documented recall completion and maintenance records showing frequent oil changes; the 2.4L and neglected examples are landmines waiting to strand you.

General Motors LLC (GM) is recalling certain model year 2010 Chevrolet Cobalt vehicles manufactured January 4, 2010, to June 23, 2010. The affected vehicles may be equipped with an improperly routed Side-Impact Sensor (SIS) wiring harness in the driver side front door. The misrouted wiring harness could cause an electrical short that disables the driver side curtain air bag.
Consequence: A disabled driver side roof-rail air bag will not deploy in the event of a crash necessitating deployment of that air bag, increasing the risk of injury to the driver.
Remedy: GM will notify owners, and dealers will inspect the sensor's wiring in the driver's door and make repairs as necessary, free of charge. The recall began on September 8, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 15075.
