The 2013 Scion tC is generally reliable within its class, but owners report a handful of recurring issues. The most commonly cited problems involve engine oil consumption and leaks, transmission and drivetrain concerns, ignition/electrical faults, and safety recalls such as airbag inflators.
Engine and performance
Common engine faults
Below are the engine-related problems most frequently mentioned by owners and noted in service bulletins for the 2.5-liter four-cylinder used in the tC.
- Oil consumption: Some owners report higher-than-expected oil usage between changes, which can lead to noticeable consumption or the need to top up more often than expected.
- Oil leaks: Leaks around the valve cover, timing chain area, or oil pan are commonly cited and may require gasket resealing or part replacement.
- Ignition misfires: Failures of ignition coil packs or spark plugs can cause rough idle, reduced power, and check engine light activation (codes such as P030x).
- Vacuum/PCV or intake issues: Vacuum leaks or PCV valve problems can trigger running faults or idle instability.
Regular maintenance, using the manufacturer-recommended oil and grade, and addressing faults promptly can reduce the risk of oil-related problems. If misfires persist, diagnose with a scanner and replace faulty coils or plugs as needed.
Transmission and drivetrain
Shifting and powertrain reliability
These items relate to how the tC's manual and automatic transmissions behave in daily use and at higher mileage.
- Manual transmission wear: Clutch chatter, slipping, or difficulty engaging gears can occur, especially with higher mileage or aggressive driving.
- Automatic transmission issues: Rough shifting, slipping, delayed engagement, or torque-converter shudder have been reported in some examples.
- CV axle/drive components: Worn CV joints or axle shafts can produce clicking noises or vibrations during acceleration or cornering.
Proper transmission service, timely replacement of worn components, and cautious shifting can mitigate many of these issues. If you notice slipping, hard shifts, or unusual noises, have the transmission inspected by a qualified technician.
Electrical and safety systems
Electrical faults and recall considerations
Electrical problems and safety-related recalls are a notable concern for some 2013 tCs, affecting daily usability and safety compliance.
- Ignition coil failures and misfires: Coil packs can fail over time, leading to misfires and reduced power.
- Electrical warnings and intermittent lights: Faulty sensors or wiring can trigger dash warnings without a clear mechanical fault.
- Power window regulator wear: Regulators can fail, causing windows to become slow, stuck, or fall down unexpectedly.
- Airbag recalls: Takata airbag inflator recalls affected many Toyota and Scion models from that era; VIN-specific recall status should be checked and addressed promptly.
If electrical issues arise, a diagnostic scan can help differentiate between battery, alternator, wiring, or sensor problems. Always verify open recalls for the VIN and have airbags addressed if required.
Maintenance, recalls, and care
Keeping a 2013 tC in good shape
Maintenance habits and recall status play a big role in long-term reliability. The most relevant points include:
- Regular maintenance: Adhere to routine oil changes, spark plug replacement per schedule, coolant checks, and brake inspections to prevent minor issues from becoming major repairs.
- Engine and transmission service: Periodic inspection of the timing chain area, valve cover gaskets, and transmission fluid (for automatics) helps detect leaks or wear early.
- Recalls and safety campaigns: Verify VIN against NHTSA and manufacturer recall databases to confirm open campaigns, particularly airbags and other safety-related items.
Staying current with maintenance and promptly addressing any recalls or service bulletins can significantly extend the life of a 2013 Scion tC and reduce the likelihood of costly repairs.
Summary
In summary, the 2013 Scion tC is not free of issues, but most problems cluster around oil consumption and leaks, transmission and drivetrain wear, ignition/electrical faults, and safety recalls. Prospective buyers or current owners should prioritize a thorough pre-purchase inspection or annual check, ensure all recalls are resolved, and keep up with routine maintenance to maximize reliability and minimize surprises on the road.
