Known Problems

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.

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.

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

Our technicians recommend replacing the shim kits when replacing the brake pads.
