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.
When backing up and applying the brakes, you may hear a squeaking noise. Scion engineers addressed this problem by modifying the shape of the brake pad and the anti-squeal shims; they also applied more grease during assembly.
Air conditioning that doesn't blow cold enough could indicate the need for adjusting the cable for the temperature blend door.
Scion xB QuestionsMy ac is only blowing minimal air. This happened around the same time my drivers window panel melted. What could be cauing it not to hardly blow out? (3 answers)

Scion xB RecallsDriver'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.
Vehicles with accessories (running boards, etc.) installed by SET are being recalled due to incorrect installation. Fasteners used to attach these accessories were installed with incorrect torque, and may detach resulting in unsafe driving conditions.
Vehicles have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle. These models are being recalled because the incorrect vehicle weight rating is shown on the information label. This could result in vehicle and tire overloading, increasing the risk of tire failure. Owners will be provided an updated vehicle weight label to correct this concern.
