They often witness firsthand the consequences of putting off essential checks and necessary fixes, which can transform minor issues into significant, costly, and even dangerous problems.
In the spirit of empowerment and practical guidance that Reader’s Digest is known for, we’ve put together a crucial list. These are the things that, if neglected, can quickly turn your trusty automobile from a source of joy into a source of stress. Paying attention to these often-delayed areas not only saves you money and headaches down the road but also contributes to your safety, the efficiency of your vehicle, and even the broader environmental well-being. Let’s dive into the core components and maintenance aspects that mechanics truly wish you wouldn’t delay.
1. **General Vehicle Repairs and Maintenance**The overarching principle of responsible car ownership, and indeed one of the most frequently delayed areas, is general repairs and maintenance. The context explicitly highlights “repairs and maintenance” as a direct cost to the individual owner. While owning a car offers immense benefits like “on-demand transportation, mobility, independence, and convenience,” these advantages are significantly diminished when a vehicle is not properly cared for. Neglecting regular check-ups or postponing necessary fixes can quickly escalate minor issues into major, expensive problems, directly impacting the economic costs associated with car usage.
Consider the complexity of a modern vehicle, which has progressively evolved from the foundational designs of inventors like Carl Benz to incorporate a myriad of features and controls. Over the decades, additional features and controls, such as rear-reversing cameras and navigation systems, have been added, making cars more intricate machines. This complexity means there are more systems that require attention, from the historical choke valve controls to contemporary electronic linkages that have replaced older physical connections for pedals. Regular maintenance schedules are designed to address these evolving complexities and ensure all systems function harmoniously.

2. **Friction Brakes (Disc and Drum Brakes)**Few components are as critical to the safety of a vehicle as its braking system, yet neglecting them is a delay mechanics frequently observe. The context clearly states that “all cars must have friction brakes (front disc brakes and either disc or drum rear brakes) for emergency stops.” This fundamental requirement underscores their indispensable role in preventing “traffic collisions,” which are tragically identified as “the largest cause of injury-related deaths worldwide.” The ability to stop effectively and reliably is paramount for the safety of the driver, passengers, and other road users.
The functionality of these friction brakes is also intertwined with modern efficiency. While “regenerative braking recovers and returns to a battery some energy which would otherwise be wasted by friction brakes getting hot” in hybrid and electric cars, the traditional friction brakes remain vital. They provide the necessary stopping power that regenerative systems cannot always fully replicate, particularly during sudden or emergency braking situations. Delaying the inspection or replacement of worn brake pads and components means compromising this essential safety net, putting everyone at risk when a quick, decisive stop is needed.
Beyond immediate safety, the context also touches upon the environmental impact of braking. It notes that “dust from brakes, tyres, and road wear” contributes to air pollution. Worn-out or improperly functioning brakes can generate excessive dust, increasing your vehicle’s contribution to local air pollution. By ensuring your braking system is in optimal condition, you are not only safeguarding lives but also doing your part to mitigate the environmental costs associated with car usage. Timely brake maintenance is a clear example of how individual action can have both personal and broader societal benefits.
3. **Tyres (and addressing wear)**The condition of your car’s tires is often underestimated, yet their impact on safety, performance, and the environment is significant. The context mentions “dust from brakes, tyres, and road wear” as a source of air pollution and specifically highlights “microplastics (from tyres)” as a pollutant released into the environment during a car’s life cycle. This indicates that tire wear is a recognized issue, and delaying attention to it has tangible consequences beyond just driving comfort. Worn tires not only reduce grip and handling, compromising safety, but also contribute disproportionately to environmental particulate matter.
Maintain proper tire pressure and ensuring adequate tread depth are simple yet crucial aspects of car care that prevent further environmental burden and enhance the vehicle’s stability. While the context notes that “the weight of the low battery stabilises the car” in electric vehicles, the overall weight and distribution, which can be affected by tire condition, still play a role. Delaying tire rotations, alignment checks, or outright replacement when necessary, can lead to uneven wear, reducing their lifespan and requiring more frequent purchases, which carries its own environmental and economic costs.
Consider the implications for performance and safety. A vehicle with worn or improperly inflated tires will have compromised handling, especially during adverse weather conditions. This directly impacts the “mobility, independence, and convenience” that cars offer, as a less reliable vehicle restricts safe travel. Mechanics understand that while tires might seem like a straightforward component, their role in absorbing road shocks, maintaining traction, and supporting the vehicle’s weight is complex and critical. Ignoring their condition means ignoring a fundamental aspect of safe and efficient driving, making timely attention to tire wear a paramount concern.
4. **Automotive Lighting (Headlights, Brake Lights, Turn Signals, Reverse Lights)**Visibility, both for the driver and for other road users, is a cornerstone of automotive safety, and the proper functioning of your car’s lights is absolutely essential. The context explicitly details the various types of lights fitted to cars: “headlights, which are used to illuminate the way ahead and make the car visible to other users,” “red brake lights to indicate when the brakes are applied,” “amber turn signal lights to indicate the turn intentions of the driver,” and “white-coloured reverse lights to illuminate the area behind the car (and indicate that the driver will be or is reversing).” Delaying the repair or replacement of any of these lights directly jeopardizes safety.
Driving at night or in adverse weather conditions becomes significantly more perilous when headlights are dim, misaligned, or completely out. The function of “making the car visible to other users” is entirely compromised, increasing the risk of “traffic collisions.” Similarly, brake lights are critical for communicating your intentions to vehicles behind you, preventing rear-end accidents. Turn signals serve the same vital communicative purpose for lateral movements. These are not mere aesthetic features but crucial communication tools on the road, integral to the safe interaction of all road users.
Even less frequently considered lights, such such as “interior lights on the ceiling,” “boot light,” or “engine compartment light,” play a role in convenience and maintenance. While not directly related to driving safety, their failure can impact practicality and obscure issues during routine checks. Mechanics are all too familiar with drivers who postpone fixing a burnt-out bulb, unaware of how profoundly this small oversight can increase the risk of an accident or lead to a traffic citation. Timely attention to all automotive lighting systems ensures you can see and be seen, upholding the safety benefits that modern vehicles are designed to provide.
5. **Vehicle Batteries (including Electric/Hybrid implications)**The battery is the heart of your car’s electrical system, whether it’s powering the starter in a traditional internal combustion engine vehicle or driving the motors in an electric car. The context mentions “batteries” in relation to increasing car weight, especially for electric vehicles, and notes that “the weight of the low battery stabilises the car” in EVs. It also mentions “automotive battery” as a specific area of focus. While the discussion primarily revolves around the *type* and *impact* of batteries, their proper functioning is implicitly vital for any vehicle. Delaying battery checks or replacement can lead to sudden breakdowns and costly electrical issues.
For conventional fossil fuel-powered cars, the battery is essential for starting the engine and powering the numerous “buttons and dials for turning on lights, ventilation, and other functions” and features like “in-car entertainment” or “rear-reversing cameras.” A weak or failing battery can leave you stranded, negating the “on-demand transportation, mobility, independence, and convenience” that cars provide. Mechanics frequently see vehicles towed in due to battery-related issues, which could often be preempted with timely diagnostic checks. The “dedicated automotive fuses and circuit breakers” are there to protect the electrical system, but they rely on a healthy power source from the battery.
In the rapidly evolving landscape of electric and hybrid vehicles, battery health takes on even greater significance. The context notes “intensive development of conventional battery electric vehicles is continuing into the 2020s,” with advancements like “lithium iron phosphate batteries are safer and cheaper.” While these innovations are for new production, owners of existing electric cars must still maintain their complex battery packs. Delaying necessary diagnostics or addressing performance degradation in an electric vehicle’s battery affects range, charging efficiency, and overall vehicle performance, which directly impacts the investment and the environmental benefits such a vehicle is intended to provide. Therefore, for all car types, the battery is a critical component whose timely care should never be overlooked.
6. **Internal Combustion Engine System (and associated emissions)**For the vast majority of cars in use, the internal combustion engine (ICE) remains the primary means of propulsion, and its proper functioning is critical not only for performance but also for environmental impact. The context explicitly states, “Most cars in use in the early 2020s are propelled by an internal combustion engine, fueled by the combustion of fossil fuels.” It also highlights the significant environmental concerns, noting that “car exhaust gas is one type of pollution” and that “cars and vans caused 10% of energy-related carbon dioxide emissions in 2022.” Delaying engine maintenance directly contributes to these negative impacts.
A well-maintained engine runs efficiently, maximizing “fuel” economy and reducing harmful emissions. The context points out that “oil consumption has increased rapidly in the 20th and 21st centuries because there are more cars,” and while this is a macro-level observation, for an individual vehicle, excessive oil consumption can be a symptom of engine problems that require attention. Neglecting these issues can lead to poor fuel efficiency, higher operating costs, and increased release of pollutants like “heavy metals and microplastics” that are generated throughout the car’s lifecycle, not just from tires. Timely engine diagnostics and tune-ups ensure that your vehicle operates as cleanly and efficiently as possible.
Moreover, the engine’s health is directly linked to the car’s overall performance and reliability. A car with a struggling engine is not only less pleasurable to drive but also more prone to breakdowns, hindering the “on-demand transportation” and “mobility” benefits. Mechanics frequently deal with issues that could have been prevented by earlier intervention, from simple spark plug replacements to more complex fuel system adjustments. With “tightening environmental laws and restrictions on greenhouse gas emissions” prompting work on “alternative power systems,” it’s more important than ever to ensure that existing fossil fuel-powered cars operate optimally to minimize their environmental footprint until the transition to electric cars is complete. Delaying engine care is a disservice to your wallet, your driving experience, and the environment.
7. **Steering Wheel and Primary Controls**The steering wheel and other primary controls are your direct interface with the vehicle, determining its direction, speed, and overall responsiveness. The context states that “cars are equipped with controls used for driving, parking, passenger comfort, and safety, normally operated by a combination of the use of feet and hands,” specifically listing “a steering wheel, pedals for operating the brakes and controlling the car’s speed (and, in a manual transmission car, a clutch pedal), a shift lever or stick for changing gears, and a number of buttons and dials for turning on lights, ventilation, and other functions.” Any delay in addressing issues with these critical components compromises your ability to safely and effectively operate the vehicle.
The precise control offered by a well-functioning steering system is fundamental to avoiding “traffic collisions,” which are the leading cause of injury-related deaths worldwide. A loose, unresponsive, or stiff steering wheel indicates underlying problems that need immediate attention. While “modern cars’ controls are now standardised,” ensuring consistent operation, this standardization also means that any deviation from expected feel or response is a strong indicator of a mechanical issue. Delaying inspection of steering components, such as power steering systems or linkages, can lead to dangerous loss of control, especially at higher speeds or during emergency maneuvers.
Beyond steering, the pedals for acceleration and braking are equally vital. While early cars had “pedals were physically linked to the brake mechanism and throttle,” modern cars “have increasingly replaced these physical linkages with electronic controls.” Regardless of the mechanism, any hesitation, stickiness, or unusual feel in these pedals demands immediate mechanic attention. These controls are the means by which you command the vehicle, and their reliability is non-negotiable for safe travel. Mechanics wish owners would recognize that any abnormality in these primary controls is a red flag, not something to simply “get used to,” as timely intervention can prevent accidents and ensure the continued enjoyment of your car’s “mobility, independence, and convenience.”
