2004 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.

2004 Scion xB Reviews

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...
tengo un problema con mi scion me da voltges de mas maxima 18.2 y lo normal es 12 - 13 yo quiero saber si alguien sabe por q ase eso..pero solo lo ase cuando esta aselerado....
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.
