If you're looking for help fixing your Mercury Automobile, look no further! Our comprehensive Mercury Automobile Troubleshooting guide will explain common issues, provide tips, and show you how to read your model's error codes.

Cracked Windshield 
While it still takes an errant rock or some other heavy catalyst, many car windshields are rolling off the assembly line with stress defects that make them more vulnerable to damage. Small ones may seem like a cosmetic problem, but any cracks can potentially compromise the structural integrity of your vehicle. 

Emission System 
Your car's emission system includes everything it needs to run efficiently while minimizing pollution. However, it also includes some sensitive equipment prone to problems. O2 sensors tell your car how much oxygen to put in the fuel mixture. Faulty O2 sensors will result in your car running less efficiently. 

Lights 
Whether a burnt out bulb or a poor connection, if your headlights, brake lights, or turn signals are out, you've got a safety issue on your hands. While the bulbs themselves are lasting longer than ever, corrosion and poor wiring is still a major concern. 

Malfunctioning Sensors 
Modern cars run with the help of an array of high-tech sensors, but those come with their issues. Faulty fuel-air sensors are some of the most common, with pricey replacements at around $250 or more. 

Falling Gas Mileage 
Believe it or not, your gas mileage is very dependent on the maintenance of your engine. Regular oil changes, replacing your engine air filter and changing your spark plugs will all make sure your car gets the most miles per gallon. 

Paint Problems 
From discoloration to chipping to scratches, auto paint defects are some of the most visible car problems to have. While most are a nuisance, keep in mind that rust spots can lead to major structural damage if left unchecked. 

Faulty Windows 
As power windows have become the norm, car owners have seen the rise of one big annoyance: Windows that don't roll up. While not too worrisome on its own, remember that too much of a gap makes you vulnerable to theft and water damage. 

Faulty Starter 
Does your car take longer than usual to start? If that’s the case and you hear a clicking sound before your car starts, your starter may be starting to fail. It’s a common problem that is pretty easy to repair. But, fix it fast, because if it fails your car won’t start.
