2009 Scion xB Problems

Check Engine Light Due to Defective VVT-i Controller

An illuminated Check Engine Light could be caused by a defective VVT-i controller, which changes cam timing for optimal power.  Updated parts are available and the repair may be covered under the powertrain warranty.

Excessive Oil Consumption

Drivers of the Scion xB 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.

2009 Scion xB Recalls

Passenger Frontal Air Bag Inflator Ruptures On Deployment

The passenger frontal air bag inflator may rupture on deployment, causing metal fragments to come through the air bag and injure occupants. Dealers will replace the passenger frontal air bag inflator or in some cases replace the air bag assembly free of charge to resolve the concern.

Driver's Door Power Window Switch Overheats And Melts

The driver's side power window master switch may lack enough proper lubricant to protect the sliding electrical contacts of the switch. This can cause a short circuit of the switch, leading to overheating and melting of the switch. Dealers will inspect the switches and apply lubricant to them if no abnormality is found. If a problem is found, the switch circuit board will be replaced. These inspections and repairs will be performed free of charge to resolve the concern.

The Master Window Switch May Overheat

Toyota and General Motors are recalling certain models because the power window master switch assembly in some of these vehicles was built using a less precise process for lubricating the internal components of the switch assembly. Irregularities in this lubrication process may cause the power window master switch assemblies to malfunction and overheat. This could result in the switch melting or possibly catching fire. Dealers will inspect and repair or replace the master window switch as necessary.

Just got my new 2009 xB. Has more potent engine than previous model years. runs well on highways. Has enough OOMPH to accelerate quickly to enter highway from entrance ramp. Still very good on gas. No problems yet.
