The 2008 Pontiac G5 shares GM's Delta platform with the Cobalt and suffers from several critical powertrain and electrical issues that can lead to catastrophic engine failure and safety-related steering problems. The 2.2L Ecotec in particular has notorious oiling system defects.
2.2L Ecotec Timing Chain and Balance Shaft Failure Leading to Engine Destruction
Common · high severity
Typical onset: 80,000-130,000 mi
Symptoms: rattling on cold start that disappears after warmup, sudden loss of oil pressure, metallic grinding from engine bay, check engine light with timing codes, catastrophic engine seizure without warning
Fix: The timing chain tensioner and guides wear prematurely, and the balance shaft drive system fails, starving the engine of oil. Once the chain jumps or balance shaft seizes, you're looking at complete engine replacement or rebuild. Timing chain job alone is 8-10 hours, but most engines are too damaged by the time symptoms appear. Short block replacement is 12-16 hours.
Estimated cost: $3,500-6,500
Electric Power Steering (EPS) Complete Failure
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: intermittent loss of power steering, grinding or whining noise from steering column, complete steering assist loss at any speed, service power steering warning, heavy steering requiring significant force
Fix: The EPS motor and control module fail, often suddenly while driving. This was recalled but many units still fail post-recall. Replacement of the entire steering column assembly is typical. 3-4 hours labor. This is a serious safety issue when it fails at highway speeds.
Estimated cost: $800-1,400
Ignition Switch Failure and Power Loss While Driving
Common · high severity
Symptoms: engine stalls while driving, all electrical accessories cut out suddenly, key gets stuck in ignition, won't start intermittently, airbags may not deploy in crash
Fix: Part of GM's infamous ignition switch recall, the switch contacts wear and allow the key to rotate out of RUN position. This kills the engine, power steering, power brakes, and disables airbags. Even recalled switches can fail. Replacement is 1-1.5 hours but requires GM-specific reprogramming of passlock system.
Estimated cost: $250-450
Automatic Transmission Oil Cooler Line Leaks and Failure
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: transmission fluid puddle under engine bay, pink fluid mixing with coolant in overflow, transmission overheating, slipping or harsh shifts, milky transmission fluid on dipstick
Fix: The transmission cooler lines rust through where they connect to the radiator, and the internal cooler inside the radiator fails, allowing coolant and ATF to mix. This destroys the transmission if not caught early. Requires cooler line replacement (2 hours) or radiator replacement plus complete fluid flush (3-4 hours). If coolant contaminated the trans, expect rebuild.
Estimated cost: $400-800 for lines/radiator, $2,000-3,500 if transmission damaged
Fuel Pump Failure
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: no start condition, engine cranks but won't fire, loss of power under acceleration, sputtering at highway speeds, whining noise from fuel tank
Fix: The in-tank fuel pump assembly fails, often stranding the vehicle. Diagnosis requires fuel pressure test. Replacement involves dropping the fuel tank. 2-3 hours labor. Sometimes just the pump, sometimes the entire sending unit assembly.
Estimated cost: $500-900
Transmission Mount Collapse
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: clunking when shifting into drive or reverse, excessive vibration at idle, visible engine movement when revving, banging noise over bumps
Fix: The front transmission mount (also called torque strut) tears and collapses due to poor rubber compound. Creates harsh shifting feel and allows powertrain to rock excessively. Easy fix at 1-1.5 hours but often ignored until it's completely separated.
Estimated cost: $150-300
Intake Manifold Gasket and Runner Valve Failure (2.4L)
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: rough idle, check engine light with lean codes, loss of power, whistling or hissing from intake, poor fuel economy
Fix: The 2.4L has variable intake runner valves that stick and fail, and the manifold gaskets leak vacuum. Requires intake manifold removal and cleaning of carbon buildup on valves or full manifold replacement. 3-4 hours labor.
Estimated cost: $400-700
Owner tips
Check oil level religiously every 500 miles on the 2.2L — these engines consume oil and low level accelerates timing chain wear
Verify ignition switch and power steering recalls were completed with VIN check before purchase
Inspect transmission fluid for pink color or coolant contamination immediately
Listen for ANY timing chain rattle on cold start — walk away if present
Budget for an inevitable short block or used engine replacement if buying high-mileage
Hard pass unless free or under $2,000 — the 2.2L engine is a ticking time bomb and the steering/ignition failures are legitimately dangerous.

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).
