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

Best car ever, and I once had a '55 Victoria Sunliner. 125k great miles. Still on original brakes after 100k. rears went til 109k. Wish it had gages, but with regular maintenance - no problems except windshields - goes through them like tissues, but this is the desert and we have lots of gravel trucking. A/c went til 115k and whole system re-done for under $1000 and cooler than ever.
My XB has 156,000 miles and gets around 26 MPG in town and 30 on the road. I have 7 friends that have an XB and all get 38 to 40 MPG around town and 42 on the road. Anyone know why some do not get the 42 MPGs? Thanks
Scion XB is a great car. Cons: Windhsield : Toss a stone at it and it will crack, so far I have about 4. More potholes, I will get even more luckier. Noise : Loud inside on the highway. Suspension : Not so great ride. Philly's potholes give me a reminder every day. Rear Hatch: Broke once, Scion issued a recall, dealer was reluctant but Scion got on the phone and made them do it...
