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.

1.8L engines may experience excess engine oil consumption. Our technicians tell us updated software is available for the engine control module (ECM) to address this problem.

An extended cranking or no start condition, and/or illumination of the Check Engine Light with codes P0300-P0304 and/or P0015 may be noted. Our technicians tell us updated powertrain control module (PCM) software is available to correct these concerns.

Vehicles with an automatic transmission may illuminate the Check Engine Light with code P0713 stored, related to the transmission fluid sensor. Our technicians tell us a revised, internal transmission wire harness is available to correct this concern. The harness does not require transmission removal to install.
