What stands out
Owners have filed 41 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This technical bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

The failure pattern owners describe
Owners describe a cascade of electrical failures centered on the ignition system. The most frequent complaint is a stuck key: the ignition switch locks in the ON position, the engine won't shut off, and the key cannot be removed or turned. Owners have been forced to disconnect batteries or pull fuses to stop the engine. Repairs run $451–$800, and some have failed again within months. Multiple owners cite over 400 similar complaints on the internet and one points to a 33-page complaint forum.
Engine stalling while driving is the second major pattern. The engine shuts off without warning at highway speeds (50–75 MPH) and low speeds alike. The radio stays on; the engine just stops. Dealerships repeatedly cannot reproduce the problem or find a cause. Owners have been stranded and narrowly avoided accidents. Spark plug replacement and fuel pump replacement (from recalls 09V419000 and 14E021000) did not cure the issue in reported cases.
Supporting failures cluster around fuel and ignition: fuel leaks (one recall unavailable in some states, costing owners $600 out-of-pocket), water entry into the throttle body in cold weather, and difficulty starting (multiple attempts required). Timing chain and belt wear at 32,000 miles is another red flag; one mechanic said he had seen the same crack pattern on the same 2.2L engine six times that year. One catastrophic failure involved a broken push pin that tore a 3–4 inch hole in the engine block and caused a fire on the interstate. Exhaust manifold cracks have also been noted at 74,000+ miles, creating carbon monoxide concerns. One owner reported a window regulator failure and loss of power steering during a stall, resulting in a crash.

Failure modes owners describe
Ignition switch stuck/key won't turn off
Ignition switch fails, preventing the key from turning to the OFF position or being removed from the ignition. Engine continues running and the vehicle cannot be shut down without disconnecting the battery or removing fuses. Multiple owners report the key becoming locked in the ignition, sometimes for extended periods.
When: Variable; some at low mileage (8,000-40,000 miles), others at higher mileage (68,000+). Some owners report problems occurring repeatedly after initial dealer repairs.
Symptoms owners cite: Key will not turn to OFF position; Key stuck in ignition and cannot be removed; Engine continues running after attempting to shut off; Requires battery disconnect or fuse removal to stop engine; Key feels rough or catches before repair; Problem occurs intermittently, sometimes resolved after parking on level surface
Repairs/costs cited: $451–$800 for ignition cylinder replacement (owner expense); some repairs repeated within months and failed again.
Recalls/TSBs owners mention: GM informed one owner that ignition switch was redesigned to prevent future issues (narrative #3). Recall 14E021000 mentioned (electrical system) but appears insufficient. Two-month warranty on replaced parts reported.
Engine stalls without warning while driving
Engine shuts off suddenly and without warning while vehicle is in motion, at various speeds and road conditions. Radio and electrical systems remain on. Engine typically restarts after stalling. No warning lights precede most incidents. Occurs intermittently, sometimes days or weeks apart.
When: Mileage ranges from 50,000 to 140,000 miles. One case started at 74,000 miles and continued for months.
Symptoms owners cite: Complete engine shutdown while driving; No warning lights before stall (in most cases); Engine restarts successfully after stall; Radio/electrical systems remain powered; Occurs at various speeds (5 MPH to 70 MPH); Intermittent; no pattern or reproducible condition; Dealerships unable to duplicate or diagnose
Codes mentioned: Check Engine Light (illuminates in some cases, not others)
Repairs/costs cited: Mechanics unable to diagnose; one instance of spark plug replacement did not resolve issue. Multiple shop visits typically yield no findings.
Recalls/TSBs owners mention: Recall 14V047000 (air bags, electrical system) mentioned but parts unavailable per one dealer. No other recalls directly address this issue according to owners.
Cracked exhaust manifold
Exhaust manifold develops cracks, allowing exhaust gases to escape into cabin. Mechanic reported seeing same crack pattern on same 2.2L 4-cylinder engine six times in one year on both Saturn Ion and Chevy Cobalt, suggesting factory defect. Exhaust odor in cabin noted when starting vehicle.
When: Began at approximately 74,000 miles and persisted over months of driving.
Symptoms owners cite: Rough running engine sound; Odor of exhaust in cabin; Headaches and nausea during long-distance driving; Engine running rougher and rougher over time
Repairs/costs cited: Manifold replacement required; mechanic observed same crack pattern on same engine type multiple times that year, suggesting systematic defect.
Engine failure with catastrophic damage—broken push pin
Push pin in engine broke without warning, creating a 3–4 inch hole in engine block. Car spun out of control on highway, caught fire as oil sprayed from engine, resulting in two 360-degree spins. No warning lights or sounds preceded failure.
When: Incident occurred while driving 70–75 MPH on interstate; mileage not stated.
Symptoms owners cite: Sudden loud boom while driving; Complete loss of engine control; Oil dumped from engine block and sprayed underneath vehicle; Engine fire; No warning lights or sounds before failure
Repairs/costs cited: Engine block hole from broken push pin; vehicle determined a total loss following fire.
Timing chain/belt premature failure
Timing chain or belt wears out prematurely at low mileage. One mechanic reported timing belt and gears were shot at 32,000 miles, shocked the parts hadn't failed during transit to shop. Another owner reports timing chain bracket failure. Service technician stated Saturn knew of problem and stocked parts in anticipation.
When: 32,000 miles (one case); timing chain bracket failure mentioned without specific mileage.
Symptoms owners cite: Loud rattling noise from front passenger side of car at idle; Timing belt and gears severely worn
Repairs/costs cited: $1,100 repair cost cited for timing belt and gear replacement at 32,000 miles.
Recalls/TSBs owners mention: No recalls. Service technician told owner Saturn was stocking parts in anticipation of occurrences, suggesting known issue.
Fuel system leak
Fuel smell detected inside or around vehicle, indicating fuel system leak. At least one owner found recall existed for fuel system in some states but not theirs, requiring out-of-pocket repair.
When: Timing not specified in all reports; one owner noticed smell when stopped or slowing down.
Symptoms owners cite: Fuel odor when vehicle stopped or slowing down; Gasoline smell coming from vehicle
Repairs/costs cited: $600 repair cost cited by one owner. Recall 09V419000 (fuel system, gasoline) mentioned as not applying in some states.
Recalls/TSBs owners mention: Recall 09V419000 (fuel system, gasoline) exists but reportedly does not apply in all states.
Throttle body icing—water ingestion
In cold weather (32°F), ice forms on throttle body. When vehicle is warmed up and driven, ice melts and water enters throttle body, causing vehicle to lose power while driving and check engine light to illuminate.
When: 32°F morning temperature; mileage not specified. Owner reports same issue happened previous year.
Symptoms owners cite: Vehicle shakes from engine area; Loss of power while driving; Check engine light illuminates; Issue recurs in cold weather
Codes mentioned: Check Engine Light
Repairs/costs cited: Dealership estimated $900 for throttle body cover but could not guarantee it would prevent recurrence.
Difficulty starting / intermittent no-crank
Vehicle fails to start on first attempt; owner must turn key multiple times over several minutes before engine cranks and stays running. Problem occurs intermittently, sometimes weekly.
When: Timing variable; one case started after oil change service.
Symptoms owners cite: Engine fails to crank on first attempt; Requires 2–3+ attempts and up to 30 minutes of waiting before starting; Occurs weekly or multiple times per week; Lights and radio come on but engine won't turn over
Repairs/costs cited: One mechanic suspected dirty throttle body; another suspected ignition problem. Battery replacement did not resolve issue.
Cold-weather starting failure
Vehicle will not start in below-freezing temperatures, making only clicking sounds. Starts normally once temperature warms.
When: Below-freezing conditions.
Symptoms owners cite: Engine won't turn over in below-freezing temperatures; Only clicking noise from starter; Normal starting once temperature rises
Intermittent clicking/relay chatter when turning off engine
When turning off the engine, rapid clicking or relay chatter occurs, sometimes lasting hours. Owner must repeatedly turn key on and off to get engine to finally shut down and release key. Symptom persists for years according to one owner.
When: Mileage and timing variable; one owner reports ongoing issue for 2+ years.
Symptoms owners cite: Multiple clicking noises when attempting to shut off engine; Engine slow to completely turn off; Key cannot be removed until clicking stops; Owner must cycle key on/off multiple times to release key from ignition
Repairs/costs cited: Starter switch replaced under recall (mentioned in one narrative) with no improvement.
Recalls/TSBs owners mention: One owner reports starter switch replaced under recall, but problem continued.
Engine surge/stutter with loss of power steering—stall at very low speed
Engine loses power and stalls while vehicle is moving at low speed, accompanied by loss of power steering and brake functionality in one case, resulting in crash into parked vehicles. In another case, engine sputters, spits, and stalls with vehicle losing power.
When: 5 MPH to 40 MPH speeds; low mileage (25,000 miles) in crash incident.
Symptoms owners cite: Engine surge, spitting, sputtering; Check engine light illuminates; Loss of power steering when stalling; Loss of brake functionality (one case); No warning prior to stall; Vehicle unable to maintain power after stalling
Codes mentioned: Check Engine Light
Repairs/costs cited: Dealership unable to find cause in multiple visits; no repairs performed in some cases.
Window regulator failure—window drops into door panel
Front driver's side window detaches from track and drops into door panel while vehicle is moving. Causes door to swing open, creating safety hazard.
When: Failure occurred while driving approximately 50 MPH.
Symptoms owners cite: Window drops from track into door panel; Door swings open; Door becomes stuck closed after incident
Repairs/costs cited: Independent mechanic repair required; window regulator replaced.
