2013 Scion tC Problems

Excessive Oil Consumption

Drivers of the Scion tC may notice excessive oil consumption between oil changes, even to the extent of the engine oil warning light displayed on the multi-function display.

This issue is known to be caused by infrequent oil changes causing engine sludge, or worn piston rings. 

The engine should be cleaned of oil sludge, and if oil consumption remains excessive, the engine may need new piston rings, or other internal components replaced. 

To avoid this issue, change the engine oil and filter every 3,000 miles, and ensure the proper grade of oil is used. 

Rough Running Conditions and Smoke From Exhaust

The head gasket may fail due to a defect in manufacturing of the cylinder block.

On this vehicle, the head bolts are known to pull the threads out of the engine block, allowing the head to slightly lift, and causing head gasket failure. Symptoms may include:

  • Overheating
  • White smoke from exhaust
  • Rough running conditions and/or inability to start or idle
  • White or cream colored oil on dipstick
  • Check engine light 
  • OBD Trouble Codes P2181, P0300

When the head gasket fails, the bolt holes for the head bolts must be repaired before the cylinder head can be remounted. 

This issue is not always preventable, but to help avoid it, never run the engine if the engine temperature is ever above the normal range.
