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.

Squeaking Noise When Applying Brakes in Reverse

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.

Cable Adjustment Needed if AC Doesn't Blow Cold Enough

Air conditioning that doesn't blow cold enough could indicate the need for adjusting the cable for the temperature blend door.

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.

Loose Accessory Installation

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.

Incorrect Vehicle Weight Rating Label

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.

Scion xB Reviews

We love our XB with 115,000 miles on it. Has always been very noisey up front even after trying different tires. I think the wheel bearings have be bad from the get go but I need a reliable answer before I spring the $600 to replace the front wheel bearings.
Got this one new and very happy with the purchase. Agree with others that exterior is kind of cheap, but so was price- especially liked the no haggle price when purchased. Over all, great car with 180000 mi and still going strong. Just got new 60K tires and wonder who is going to give out first?
2004 xB = Best car I have ever owned! I can carry wife, 2 kids, alto, tenor, and bari saxes, and still get 32 mpg in town. No other car can match. Could use better high gear ratio - engine runs little faster than necessary on highway. 72000 miles - zero issues.
