Used Saturn Ion Buying Guide: 2003-2007, Red Line, Ignition Recalls to Check

Most used Saturn Ions worth buying today are 2005-2007 sedans with the conventional four-speed automatic or the five-speed manual, and none of them is worth buying until GM's records show the ignition switch recall (14V047) and the ignition cylinder recall (14V171) done for that exact VIN. Every Ion from 2003 through 2007 is in both. The newest one is now 19 years old, so you're shopping condition and paperwork first and the badge a distant second.

I pulled all five Ion model years from NHTSA's recall API on Sunday morning, October 18, 2026, and got 12 campaigns back, two of them for aftermarket parts. For the car itself I leaned on Consumer Guide's 2003-07 Ion review, which is blunt about the cabin ("budget-grade") and kind about the steering. Saturn itself is long gone, and GM's recall notices for the Ion tell owners that GM dealers do the repairs.

Which Ion, and which gearbox

The Ion replaced the S-Series for 2003 as a sedan and a "Quad Coupe" with two small rear-hinged doors that only open after the fronts do. Both kept Saturn's dent-resistant plastic side panels, which is honestly the best thing about a 20-year-old Ion in a parking lot. The regular engine is a 2.2-liter four with 140 hp. For 2003-2004 the automatic choice was odd: a CVT on coupes and a five-speed automatic on sedans. Saturn dropped both after 2004 and fitted a plain four-speed automatic, and a 170-hp four became optional on the Ion 3 for 2006.

The Red Line coupe arrived midway through 2004 with a supercharged 2.0-liter, 205 hp, a manual only, sport suspension and four-wheel disc brakes, and it wants premium fuel. If you want the cheap commuter, I'd skip the early CVT and five-speed automatic cars and look for a 2005 or later. If you want the Red Line, budget for the fact that it's the one an earlier owner most likely drove hard.

Recalls to clear by VIN

14V047, 2003-2007: the ignition switch can slip out of Run from key ring weight or a jolt, turning off the engine, and the air bags may not deploy. Until it's fixed, GM told owners to carry the ignition key alone on the ring.
14V171, 2003-2007: the key can come out when the ignition isn't in Off, so the car can roll away. Dealers replace the cylinder and recut keys.
14V153, 2004-2007: sudden loss of electric power steering assist.
Fuel leaks: 04V003 (2003-2004 2.2 fuel filter corrosion), 04V281 (2004 supercharged engine fuel feed pipe), and 09V419 plus 12V459, a cracked fuel pump module port on 2006-2007 cars sold or registered in a list of hot states (Arizona and Nevada for 2006; Arizona, California, Florida, Nevada and Texas for 2007).
2003-2004 extras: 04V004 (power windows and sunroof could work with the ignition off once the passenger door opened) and 04V547 (front turn signals and running lights dropping out).

One sneaky entry, 14E021, covers aftermarket ignition switches sold under the Wells, Duralast, Airtex and Carquest names. So an Ion that got a parts-store switch years ago can still need the GM fix. Run the VIN on GM's recall lookup and the NHTSA API, and use our Saturn recall check by VIN walkthrough for reading the results.

The ignition story, briefly

Fortune's 2015 report says the compensation fund run by Kenneth Feinberg linked the switches to 124 deaths and 275 injuries, and that the problem was flagged as early as 2001 in a pre-production report for the 2003 Ion. That's why I won't take "the recall's done" from a seller. Our GM ignition switch recall check covers how to confirm it, and the Ion's mechanical twin is in our used Chevy Cobalt guide.

Trouble spots Consumer Guide lists

Most of its list is early-car stuff. On 2003-2004 engines, coolant loss with no visible leak can point to a porous cylinder head casting that has to be replaced, which on a car this cheap can end the deal. Exhaust manifold bolts on 2002-2004 engines can work loose and tick like a lifter. 2003 cars can drip A/C condensate onto the passenger floor, and some have HVAC foam that falls off and jams the vent doors. Pull the passenger floor mat and feel the carpet, because a wet carpet on a $3,000 car gets blamed on a flood that never happened, or a flood gets blamed on the A/C.

Drive it and turn the wheel at parking speed a few times, since the power steering recall is about assist that quits. Look at the center-mounted gauges with the engine running to make sure every warning light comes on and goes off. Then decode the VIN with our Saturn VIN decoder guide to confirm the engine, since a Red Line badge costs a few dollars online. Shopping the bigger Saturn instead? See our used Saturn Vue guide.

Paperwork on a 19-plus-year-old car

Search NMVTIS for salvage, junk and flood brands, then pull a full history. Cars this old change hands a lot, often in cash deals with a seller-printed report that may not even match the VIN. Check the VIN on the dash, the door label and the title before you trust any printout.
