2005 Scion tC Recalls, Problems & Maintenance

The 2005 Scion tC has no open NHTSA recalls. Owners report 7 recurring issue clusters, led by “Tire sidewall separation and blowout.” Every Scion is another company's car in a hoodie, and the maintenance follows the donor. Most models (xA, xB, tC, xD, iQ, iM) are pure Toyota: 5,000-mile or 6-month service visits, oil every 10,000 miles on the 0W-20 cars (5,000 on early models), iridium plugs at 120,000, and famously little else. The FR-S is a Subaru boxer underneath and marches to Subaru's beat, with plugs at 60,000 and its own coolant schedule. The iA is a Mazda2 with Skyactiv service intervals. Parts and service remain easy through Toyota dealers, which is most of why used Scions make sense.

Save this car as:

No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Essential maintenance

Critical for safety and preventing major damage

Oil & Filter Change

Every 10,000 mi

0W-20 models (2011+ tC, iQ, iM): every 10,000 miles or 12 months with 5,000-mile checkup visits between. Earlier models: every 5,000 miles or 6 months. FR-S and iA: every 7,500 miles. Severe use halves all of these.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 5,000 mi

Every 5,000 miles or 6 months per the Toyota-pattern schedule; 7,500 on FR-S and iA.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 5,000 mi

Checked at every service visit.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid

Every 30,000 mi

Toyota's US guides list inspection only, no replacement interval; the FR-S schedule does replace it, around every 30,000 miles. Every 2 to 3 years is sound practice on any of them since fluid absorbs moisture with age.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Engine Air Filter

Every 30,000 mi

Every 30,000 miles or 36 months across the lineup.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Spark Plugs

Every 120,000 mi

Iridium plugs at 120,000 miles on the Toyota-engine cars. FR-S: 60,000 miles, the big schedule difference on the Subaru boxer. iA: roughly 75,000 per Mazda practice. Note that 2005-2010 tC engines with oil-consumption habits can foul plugs early.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 30,000 mi

Every 30,000 miles or 36 months on the Toyota schedule; sooner in dusty conditions.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Engine Coolant

Every 100,000 mi

Toyota Super Long Life: first change at 100,000 miles or 120 months, then every 50,000. FR-S uses Subaru coolant: first at 135,000 or 11 years, then every 75,000.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Transmission Fluid

Every 60,000 mi

Toyota WS fluid has no normal-schedule change; the factory book calls for it at 60,000 and 120,000 only under towing or heavy loads. FR-S automatics: every 60,000 miles or 5 years. A drain and fill around 60,000 is cheap insurance on any of them.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Drive Belt

Every 60,000 mi

First inspection at 60,000 miles or 72 months, then every 15,000. All Scion engines are chain-driven; there is no timing-belt service on any model.

Estimated cost — typical U.S. ranges

Dealer

~$195–$235

Shop

~$135–$165

DIY

~$20–$50

DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.

Fatal crash history & reported problems

driver deaths

59

passenger deaths

1

not recorded by seat

202

occupant deaths

Crash years covered: 1990–2024 This model year first appears in 2004 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.

Why we show driver deaths too

Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.

Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.

IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
