Most reported problems

NHTSA lists 898 owner complaints for this model year[1]. Of those, 51 mention a crash, 4 a fire, 35 injuries and 3 deaths[1]. These are unverified reports from owners, and one complaint can name more than one part of the car. The counts are not adjusted for how many cars were sold.

Here are the biggest complaint groups:

Component group Complaints Crashes Median mileage at failure
Steering[2] 345 16 86,000
Electrical system[3] 331 10 52,000
Power train[6] 60 2 64,000
Engine[7] 56 0 82,000
Air bags[8] 52 30 55,000
Fuel/propulsion system[9] 36 0 105,000
Speed control[10] 27 3 93,000
Exterior lighting[11] 25 1 51,200

Steering. In a sample of complaints we read, owners describe the power steering assist cutting out while driving, leaving the wheel stiff, sometimes with a warning light. Some say it came back after they restarted the engine. A few say they paid for the repair after the warranty ended[2]. The steering group also has 4 injuries[2].

Electrical system. In the sample, owners describe the engine dying while driving, with the dealer finding nothing wrong. Others describe a car that would not start, often in cold weather[3]. The group has 3 fires and 8 injuries[3].

Engine and power train. The engine sample describes stalling, hard starting in cold or damp weather and a couple of cracked cylinder heads[7]. The power train sample describes odd shifting, such as downshifting while braking, slipping or hesitating. Several texts say the dealer could not reproduce the problem[6].

Air bags. This group is small at 52 complaints, but it has 30 crashes and 22 injuries[8]. All 3 deaths in the model year's complaint total are listed under air bags[8][1]. Read this together with the ignition switch recall below, which says the air bags may not deploy if the switch moves out of the run position[12].

Recalls

NHTSA lists eight recalls for this model year[4]. Newest first:

Before you buy, check the VIN to see which of these are still open on a specific car.

Fuel economy

The EPA lists four versions of the 2004 Ion, all front-wheel drive:

Engine and transmission City / highway / combined MPG Est. annual fuel cost
2.0L, manual 5-speed, premium fuel[20] 20 / 26 / 23 $3,550
2.2L, automatic (variable gear ratios), regular[21] 22 / 29 / 24 $2,800
2.2L, automatic 5-speed, regular[22] 20 / 30 / 24 $2,800
2.2L, manual 5-speed, regular[5] 23 / 32 / 26 $2,600

The annual cost uses the EPA's current fuel price assumptions, not prices when the car was new. The 2.0L needs premium fuel, and its estimated annual fuel cost is the highest of the four[20].

Safety ratings

NHTSA's 5-Star Safety Ratings list this model year as not rated, both for the 2-door[23] and the 4-door[24].

Engine and size

The EPA lists a 2.0L 4-cylinder[20] and a 2.2L 4-cylinder[21]. Recall records also mention a supercharged 2.0L (LSJ) engine[16].

These sizes are Canadian-market specifications from Transport Canada, so they can differ slightly from US cars:

Variant Length Width Height Wheelbase Curb weight
4-door quad coupe[25] 185 in 68 in 56 in 103 in 2,751 lb
4-door sedan[26] 185 in 67 in 57 in 103 in 2,692 lb

The 2004 model year has the most recalls of the five years. Its 898 complaints are the second highest, behind 2006 with 1,235[4]. The 2005 year has the fewest of both. Complaint counts are not adjusted for sales, so treat them as a rough guide.

Should you buy a used 2004 Saturn Ion?

The record for this model year is mixed at best. Steering and electrical complaints are the largest groups, and owners in the sample describe the car losing power steering assist or stalling while driving[2][3]. Eight recalls are on file, including three from 2014 that involve the ignition and power steering[13][14][12]. If you are considering one, check the VIN for open recalls and ask whether the ignition and power steering work was done, and confirm with a dealer whether repair parts are available now, since our data cannot say. The complaint numbers are unverified and not adjusted for sales, so they show where owners reported trouble and not how likely any one car is to fail.

Complaints submitted to NHTSA by owners; unverified reports, one complaint can name several components. Complaint counts are not normalized by sales; compare years of the same model, not different models. EPA annual fuel cost uses EPA's current fuel price assumptions, not the price when the car was new. Horsepower is the rating listed for EPA test vehicles. Dimensions are Canadian-market specifications and can differ slightly from US models.
