NHTSA Complaint #11502938 — 2002 FORD FOCUS

I drive a 2002 Ford Focus Sedan. My engine light is on, warning light for trunk door ajar light is on (even though the trunk is securely locked, my front headlights due not work consistently (sometimes work, sometimes don't). My trunk does not always latch secure after I close it as well. I took my car to Advanced Auto Parts and had my engine light diagnosed. Engine codes that resulted were: B1318, B1881, C1947, B2438, B2434, P0457. The representative tested my battery and found that the voltage was slightly lower than it should be. My concern is for my safety as well as the safety of others. Do we have some manufacturer defects on this particular vehicle? Have other concerns which could be the result of vehicle wear and tear, or/and due to manufacturer defects as well. Inner tie rods need replaced as well as control arms/bushings, as reported to me by a mechanic. I have seen recall reports related to the 2002 Ford Focus in which there has been issues directly related to what I'm reporting, which is another reason I'm filing a report. Thank you. The contact wanted to add that the wipers are experiencing an electrical issue as well. When in use, the wipers cannot be switched off when it is at the highest position because it will not return in the downward position.
