Car mechanics across the country are urging drivers to reconsider certain habits that can lead to costly repairs and safety issues. These common practices not only affect the longevity of vehicles but also contribute to higher maintenance bills and even accidents. Understanding these habits is crucial for drivers who want to keep their cars in optimal condition and avoid unnecessary expenses.

1. Ignoring the Check Engine Light

One of the most concerning habits drivers exhibit is ignoring the check engine light. According to a survey by the Automotive Service Association, around 60% of drivers continue to operate their vehicles despite this warning. This light can indicate various issues, from minor problems like a loose gas cap to serious engine malfunctions that could lead to breakdowns.

2. Neglecting Regular Oil Changes

Oil changes are essential for maintaining engine health, yet many drivers delay this simple task. The American Automobile Association (AAA) recommends changing the oil every 5,000 to 7,500 miles, depending on vehicle type and oil used. Skipping these changes can lead to engine wear and costly repairs, especially in models like the 2018 Honda Civic, which require specific oil types to function efficiently.

3. Overlooking Tire Maintenance

Many drivers fail to regularly check tire pressure and tread depth, leading to safety hazards and reduced fuel efficiency. The National Highway Traffic Safety Administration (NHTSA) reports that under-inflated tires contribute to over 11,000 accidents annually. Mechanics advise checking tire pressure monthly and rotating tires every 6,000 to 8,000 miles to ensure even wear.

4. Not Replacing Worn Brake Pads

Ignoring warning signs of worn brake pads can be dangerous, yet many drivers do just that. Mechanics recommend replacing brake pads every 30,000 to 70,000 miles, depending on driving habits. Delaying this critical maintenance on vehicles like the 2020 Toyota Camry can lead to more severe issues, including damage to the rotors, which can cost hundreds of dollars to repair.

5. Using the Wrong Fuel Type

Filling up with the incorrect fuel type can damage a vehicle’s engine. Many drivers mistakenly believe that using regular gasoline in a premium-fuel-recommended vehicle, such as the 2021 BMW 3 Series, is a cost-saving measure. However, this practice can lead to reduced performance and increased emissions, ultimately costing more in repairs and fuel efficiency.

6. Overloading the Vehicle

Exceeding the manufacturer’s recommended weight limit can strain a vehicle’s suspension and brakes. The Federal Highway Administration states that carrying excessive weight can reduce fuel economy by 1% for every 100 pounds over the limit. Mechanics warn that this habit can lead to premature wear and tear on components, especially in SUVs and trucks designed for heavy loads.

7. Neglecting Windshield Wipers

Many drivers forget about the importance of functioning windshield wipers, which can severely impact visibility during inclement weather. The American Automobile Association (AAA) suggests replacing wipers every six months to a year. Failing to do so can lead to dangerous driving conditions, particularly for vehicles like the 2019 Subaru Outback, which are often driven in varying weather conditions.

8. Skipping Routine Inspections

Regular vehicle inspections are key to identifying issues before they escalate. Many states require annual inspections, but drivers often neglect them. The National Institute for Automotive Service Excellence emphasizes that routine checks can catch problems early, saving drivers from unexpected breakdowns and costly repairs down the line.

9. Driving with a Low Fuel Tank

Driving on a low fuel tank can damage the fuel pump, which relies on gasoline for lubrication and cooling. Mechanics note that consistently letting the tank drop below a quarter full can lead to premature fuel pump failure. This issue is particularly prevalent in older models, such as the 2010 Ford Focus, which may not have the same fuel pump durability as newer vehicles.

10. Procrastinating on Battery Replacement

Car batteries typically last between three to five years, yet many drivers ignore signs that a battery is failing, such as slow engine cranking or dimming headlights. The Car Care Council recommends a battery check every six months. Waiting too long to replace a failing battery can leave drivers stranded, particularly in colder climates where battery performance can diminish more quickly.

By addressing these ten habits, drivers can not only enhance their vehicle’s performance but also save on maintenance
