The 2005 Cobalt is a basic compact with some serious weak points: the ignition switch is a documented safety hazard, the 2.2L Ecotec can consume oil and fail catastrophically if neglected, and the electric power steering fails more often than it should. Cheap to buy, but beware deferred maintenance.
Ignition Switch Failure (Recalled, but check replacement status)
Common · high severity
Symptoms: Engine shuts off while driving, Key gets stuck in accessory position, All electrical cuts out suddenly, Airbags may not deploy in crash
Fix: GM recalled millions of these. Replacement ignition switch and lock cylinder kit takes 1.5-2 hours if done correctly. Verify recall was completed; many used Cobalts still have the defective part.
Estimated cost: $0 if recall open, $250-400 if paying out-of-pocket
2.2L Ecotec Oil Consumption and Piston/Ring Failure
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Burning 1+ quart per 1,000 miles, Blue smoke from exhaust on startup, Loss of compression, Knocking or rattling from crankcase, Check Engine light with misfire codes
Fix: Carbon buildup and worn piston rings are endemic on neglected 2.2L engines. Catch-can and frequent oil changes help, but once rings fail you're looking at 12-16 hours for a short block or engine rebuild. Many shops swap in used engines (8-10 hrs) instead.
Estimated cost: $2,500-4,500 rebuild, $1,800-3,000 used engine swap
Electric Power Steering (EPS) Motor Failure
Occasional · high severity
Typical onset: 90,000-150,000 mi
Symptoms: Power steering cuts out intermittently or completely, Steering becomes extremely heavy at low speeds, Service StabiliTrak and Power Steering warning lights, No warning before failure in some cases
Fix: The steering column-mounted EPS motor and control module fail, especially after water intrusion or heat cycling. Replacement motor/module is 2-3 hours labor. Remanufactured units are common but quality varies.
Estimated cost: $500-900
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: Red fluid dripping near radiator or under engine, Transmission slipping or shifting harshly, Burnt transmission fluid smell, Low fluid level on dipstick
Fix: The rubber cooler lines crack and split where they connect to the radiator or trans. Replace both lines as a set (1.5 hrs), flush the trans if contaminated, and top off. Cheap fix if caught early; deadly for the 4T45E automatic if fluid runs low.
Estimated cost: $200-400 just lines, $600-1,000 if trans service needed
Fuel Pump and Fuel Filter Clogging
Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Hard starting or no-start condition, Sputtering or hesitation under load, Engine stalling at idle or when warm, Whining noise from fuel tank area
Fix: The in-tank fuel pump strainer clogs on cars that sat or ran dirty gas. Pump replacement is 2-3 hours (drop the tank). The external fuel filter (if equipped) is often overlooked and should be replaced every 50k mi.
Estimated cost: $400-700
Transmission Mounts Collapsing
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking on shifts or acceleration, Excessive engine movement visible under hood, Vibration at idle in Drive, Shifter feels loose or notchy
Fix: The torque-axis mount (top dogbone) and side transmission mount soften and tear. Replace both at once (1.5-2 hrs). Cheap insurance against driveline vibration and stress on axles.
Estimated cost: $250-450
Owner tips
Check oil every 500-1,000 miles on the 2.2L; add as needed to prevent ring and bearing damage.
Verify the ignition switch recall (14V047) was completed; this is non-negotiable for safety.
Replace transmission cooler lines and fluid at 80k mi before they fail and starve the trans.
Inspect power steering function on test drive — total loss of assist with no warning is common and dangerous.
Cheap wheels, but high-stakes gambles on ignition switch, oil consumption, and EPS failures make this a 'know what you're buying' proposition — full service records and recall confirmation are mandatory.

UCI-FRAM Group is recalling certain LS1328 ignition Switches sold as Wells LS1328, Duralast LS1328, Airtex 1S6097, and Carquest 53-27479, and LS1497 Ignition Switches sold as Wells LS1497, Duralast LS1497, Airtex 1S10961, and Carquest 53-27967, for use on various General Motors model and model year vehicles during repair and replacement of the original ignition switch. The weight on the key ring and/or road conditions or some other jarring event may cause the affected ignition switches to move out of the run position, turning off the engine and disabling the air bags.
Consequence: If the ignition switch moves from the run position to accessory, the car would stall and the air bags will not deploy in the event of a crash, increasing the risk of personal injury to the occupants.
Remedy: UCI-FRAM Group has notified its purchasers to quarantine and return all inventory. Any switches already installed in vehicles will be replaced by GM dealers as part of NHTSA recall 14V-047, free of charge. UCI-Fram's purchasers should contact UCI-FRAM Group at 1-800-890-2075. GM vehicle owners requiring additional information on that recall campaign should contact GM at 1-800-222-1020 (Chevrolet), 1-800-762-2737 (Pontiac) or 1-800-553-6000 (Saturn).
