2003 Subaru Impreza ProblemsCheck Engine Light Due to Failed Knock Sensor
There have been reports of "clutch chatter," particularly when driving the vehicle from a cold start. If the issue was reported by the owner while the vehicle was still under warranty, the dealer may replace the clutch with improved parts.
Sometimes the Check Engine Light illuminates because the computer detects misfires. Subaru released an improved spark plug wire set to solve the problem. The ignition coil should also be inspected for carbon tracks or short circuits between the contacts
2003 Subaru Impreza Questionsreplace timing belt early if repairing head gasket leak? (1 answer)
I have confirmed that I have an oil leak on the left head gasket (and smaller leak on the right side). There are 87,000 miles on the car. Does it make sense to get the timing belt + pump replaced now to avoid taking everything apart again at 105k miles, since I am getting the head gaskets fixed?
i replaced my oil temp sencor (drain plug) and guage is still not accurate. what should i look for to resolve this matter?
how can i install my front plate without drilling holes in my bumper?
2003 Subaru Impreza RecallsFront Lower Control Arms May Break
The front lower control arms may break at the hanger brackets due to corrosion. This corrosion is commonly a result of the hanger bracket being exposed to salty conditions, such as roads where salt is used as a snow melting agent. A broken control arm can result in loss of vehicle control, increasing the risk of a crash. Dealers will inspect the affected control arms and rustproof or replace them as necessary. The Subaru recall number is WVX-34.
