Pothole Causes, Solutions, and Mechanic Insight

Pothole Causes, Solutions, and Mechanic Insight

Potholes have seemed to become an epidemic across the nation. Drivers come in almost every day with trouble from roads. Some issues, like alignment troubles, can build over time. Other damage, like bent rims, can come on suddenly. However, potholes remain a constant nuisance. So, what causes potholes? What can you do about it? Our local mechanics are here with insight. 


What Causes Potholes?


Smooth asphalt is unlikely to face any direct impact in the middle of the street. So how do potholes form? The answer starts at the “roots” of our roads. On the surface, we see strong, industrial, unbreakable asphalt. However, deep beneath the pavement is soil ready to cause trouble. 


All potholes start with rain. Moisture can collect in the ground under the asphalt—seeping into the sand or dirt through small cracks in the road. This rain leads to three different causes of potholes:

  • Water can start eroding the underlying soil, leaving patches in the road’s structural support. Then, when a heavy truck or constant traffic stresses the patch of road, it can cave in—creating a new pothole.
  • We can also see tree roots and other vegetative regrowth begin seeking out the moisture collecting under the asphalt, impacting the road’s structural integrity. 
  • In other cases, freezing weather can cause the water to expand. When the ice thaws, it leaves a cavity in the pavement. As traffic drives over this cavity, it will cave in—creating a new pothole. 


The Current Pothole Trends


Why are potholes everywhere? Extreme weather conditions, staffing shortages, high traffic, and supply chain issues are some of the problems contributing to the predominance of potholes on the roads today. There are five main reasons we are seeing an increase in potholes in recent years. 


1: Changes in Traffic Patterns


For a low-traffic road, asphalt can last 25 years or more. However, as home development efforts continue with intensity throughout the country, even smaller backroads are seeing more movement. Naturally, this causes more pavement wear and tear, increasing the frequency of potholes. 


2: Supply Chain Issues


In 2021, supply chain issues led to a shortage of asphalt—delaying road projects and leaving potholes unfilled. This issue caused government officials to fall behind on pothole filling. With potholes becoming more prominent while repair efforts fall behind, officials cannot seem to catch back up. 


3: Change in Weather Patterns


As mentioned above, all potholes start with rain. In North Carolina, recent years have brought some of the highest levels of heavy rain the state has ever reported. More rain naturally leads to an increase in potholes. The 2022 NC Climate Summary provided the following chart, which clearly displays record-high precipitation in the 2015-2020 bar. The charts are updated in 5-year intervals, with the next update coming in 2025. However, we have continued to see high precipitation levels across the state, and experts expect this number to continue rising.

4: Underreporting of Potholes 


As we explain below, patching a pothole starts with a report to the NCDOT. However, the predominance of potholes can create a type of bystander effect. If all drivers assume someone else has already reported a severe pothole in the area, you might find that nobody ever actually reports it. In other cases, many drivers can fall into a negative mindset that leads to underreporting. You might think, “It is useless—there are too many potholes to report.” When drivers accept the fate of a bumpy commute, roads are less likely to get the help they need. 


5: Pavement Life Cycles


Healthy pavement can last 25+ years without issue. However, all of the above concerns will shorten the asphalt lifespan. Additionally, we encourage you to look up when the state built pothole-covered roads in your area. You are likely to find that they are naturally reaching the end of their lifespan. 


The Dangers of Potholes on the Road


Whether they make you spill your coffee or wake the baby sleeping in the backseat—we have all been inconvenienced by potholes on the road. However, beyond just personal inconveniences, potholes can cause costly vehicle damage, including:


How to Tell If Your Car Has Pothole Damage


After driving over a huge pothole, have you ever noticed your car immediately fall silent? Perhaps this is our way of instinctually listening for an issue. Here is a look at the signs your vehicle experienced pothole damage:

  • Feel it out: If your tire experiences a blowout, the damage will be immediate and noticeable. However, pothole damage often comes in more subtle internal signs. For example, steering wheel shaking can signify pothole damage with your alignment or suspension system. 
  • Visual inspection: Take a look at your tires and the bottom of your car after hitting a pothole. Do you see any signs of an issue? Some problems, like tire bubbling, will be obvious. 
  • Visit a mechanic: The safest option is to have a professional take a look at your vehicle. Experts can diagnose potential issues. They can also advise whether or not you have a possible case for apparent pothole damage. 


Should I Fill In My Local Potholes?


In recent news, former California governor Arnold Schwarzenegger took matters into his own hands: filling a pothole near his home. While drivers might rejoice in this decision, it can actually have serious consequences:

  • Potential Dangers: Road work can be dangerous. The government can shut down lanes and re-route drivers to maintain safe transportation during road repairs. Without the right precautions, you could create car accidents or risk personal injury trying to repair a road yourself. 
  • Delaying Real Repairs: It can be hard to fill a pothole to professional standards. Sometimes, your DIY solutions could delay long-lasting professional repairs—as experts will need to undo your work before starting. In other cases, you might actually make the pothole worse by trapping moisture under the asphalt. This water will expand during the following winter freeze, bringing the pothole back larger than before.
  • Personal Liability: You may be personally liable if an imperfect pothole fix causes any trouble. For example, underfilling a pothole could allow surface-level water collection while preventing the water from seeping through the cracks and into the ground. This change in your road’s structure could increase the risk of hydroplaning and car accidents. 
  • Mistaken Potholes: Or, as in the case of Arnold Schwarzenegger, the pothole may not be a pothole at all. The former governor actually filled in a service trench required to complete vital gas line repairs. 


No news yet on whether or not Arnold Schwarzenegger had to pay to have the service trench dug again. However, the reward is not worth the risk of filling potholes yourself. 


What Can You Do About Potholes?


While you can’t fill a pothole in yourself, there are some steps you can take to keep your car protected:

  • Always report potholes on the road to your local authorities. 
  • Make sure your tires are properly inflated. Low tire pressure will leave you more prone to rim damage from potholes, while overinflated tires make it likely you will experience a tire blowout. 
  • Drive slowly over known potholes. 
  • While it might go without saying, avoid these hazards on the road when you can. For example, if you know the highway’s right lane has a severe pothole, remind yourself to drive in the left lane until the coast is clear. 
  • Consider finding an alternative route to your destination for severe and unavoidable potholes until the repairs are completed. 
  • Make sure you are keeping up with regular maintenance and vehicle inspections. If you are hitting frequent potholes, you should get your alignment checked for free at a local mechanic. This inspection can prevent more extensive damage from spreading, like uneven tire wear. Regular maintenance can also help you affirm to government officials or your insurance company that the damage was, in fact, caused by potholes. So, let’s take a closer look at how you can get repayment for pothole service repairs. 


How to Save Money on Pothole Repairs


Before you delay getting significant repairs caused by pothole damage, you should know these repairs may be covered for free. However, before we dive in, it is worth noting that you should visit a mechanic as soon as you experience pothole damage.

  • Immediate action will help keep your claim valid. If you file a property damage claim to the government after the pothole has been filled, it is more likely that your claim will be denied—even if you otherwise qualify for compensation. 
  • If you continue driving on a damaged tire, for example, it could create even more vehicle damage that will not be covered. 
  • In some cases, you might need a mechanic to attest that the damage to your vehicle was consistent with pothole damage. Additionally, you might need to have paid the costs to verify the final total for a claim. 


Will Insurance Cover Pothole Problems?


Yes, some car insurance policies—like collision insurance—will cover pothole damage. In these cases, you would simply need to pay your deductible. It is worth checking with your insurance agent to see if your vehicle can be repaired for free. 


Will the Government Cover Pothole Damage?


In some cases, your pothole damage may be covered by your local government. There are three noteworthy considerations here:

  • First, is the road state-maintained? A majority of roads are owned and maintained by the government. However, subdivisions and residential streets are often privately owned. For example, your home’s road might belong to the community and receive maintenance under the HOA. 
  • Second, was the pothole reported to the local government? NC drivers can click here to report a pothole. Claims are only valid if this was a known, reported pothole. 
  • Finally, how long ago was the report filed? The government requires a reasonable amount of time to respond to pothole reports before they can be held accountable. 


If a pothole was reported without reasonable action from the government, officials might take responsibility for the damage it caused. North Carolina drivers can click here to file a property damage claim to the NCDOT

It can be hard to keep up with all of the care that your vehicle needs. When a light comes on in your dashboard or a mechanic lets you know you are due for a new service, this can surface lots of questions. One common source of service confusion is the coolant flush. Thankfully, Chapel Hill Tire has you covered. Here is a look at the answers to all of your common coolant flush questions. Is it Really Necessary to Flush Coolant? Perhaps the most common question surrounding this service is, “Are coolant flushes really necessary?” The short answer is YES.  Your engine creates friction and heat in order to run properly. However, your engine is also made of metal pieces, which are malleable and vulnerable when heated. Extensive heat can cause a blown radiator, cracked gasket head, warped cylinder, and melted seals, among numerous other serious, dangerous, and expensive issues. To protect your engine from this heat, your radiator contains coolant that absorbs excess heat. Over time, your coolant will become worn out, burnt, and contaminated, causing it to lose its cooling properties. While you might not like hearing that you are due for an extra service, coolant flushes are necessary for a safe and healthy vehicle. Does Coolant Matter During Cold Weather? As we approach the fall and winter temperatures, you may become increasingly tempted to ignore coolant services. Does coolant matter in the cold weather? Yes—the friction and power of your engine generate heat year-round. While the summer temperatures certainly do intensify engine heating, coolant is still incredibly important in the winter. Additionally, coolant contains antifreeze, which will protect your engine from the dangers of cold temperatures. What is the Difference Between Coolant and Radiator Fluid? When reading your owner’s manual or various resources online, you might find “coolant” and “radiator fluid” terms used interchangeably. So are they the same thing? Yes! Radiator fluid and coolant are different names for the same material. You might also find it referenced as “radiator coolant,” which offers the best of both worlds. Is Coolant the Same as Antifreeze? Another common question that drivers ask—“Is antifreeze the same thing as coolant?” No, these two are not quite the same. Rather, coolant is the substance used to regulate the temperature of your engine. Antifreeze is the substance within your coolant that prevents freezing in the winter. You might find some sources that refer to coolant as providing cooling properties only; however, since the coolant often contains antifreeze, it has widely become a general term that encompasses both. How Frequently Are Coolant Flushes Needed? Generally speaking, a coolant flush is often needed every five years or 30,000-40,000 miles. However, coolant flush cadence can be impacted by your driving patterns, local climate, vehicle age, make, and model, as well as other factors. Consult your owner’s manual or a local professional for insight on whether or not you are due for a coolant flush. Additionally, you can look for signs of a needed coolant flush. These include a sweet maple syrup car smell and vehicle engine overheating. Take a closer look at these and other signs of a needed coolant flush here . How Much Does a Coolant Flush Cost? Many mechanics try to hide their prices from customers, which can create questions, confusion, and unpleasant surprises. While we cannot speak for the costs you will face at other mechanic shops, Chapel Hill Tire offers transparent pricing for every coolant flush and other services . Our coolant flushes cost $161.80, which includes the safe disposal of your contaminated fluid, professional-grade cleaning of your cooling system to remove rust and sludge, high-quality new coolant, coolant conditioner to keep it preserved, and a visual inspection of your entire cooling system.

Oil Change Prices Why do most mechanics and dealerships hide the costs of their services? You might be wondering if they will try to take advantage of your visit and overprice their services. Or perhaps they think that their oil changes are so expensive that displaying their service costs would deter customers from visiting the shop. At Chapel Hill Tire, we value our customers, which is why we display transparent pricing for all of our services. Here is everything you need to know about the actual price of oil changes. What Does an Oil Change Involve? One of the most common vehicle services—and arguably the most important for keeping your engine protected—is the oil change . This product keeps your engine lubricated so that it can function without harmful friction. Over time, your oil becomes filled with debris, making it less effective in providing proper protection for your engine. Your oil levels also become depleted as your engine burns through your oil supply. This is where an oil change comes in. Not only do you need to supply your vehicle with oil, but you also need to remove the old oil and replace the filter that prevents the harmful debris from entering your engine. If you partner with an outstanding oil change expert, you will also receive routine vehicle checks included in the price of your oil change. On average, you need an oil change every 3,000 miles or every six months , whichever comes sooner. Maintaining regular oil change services will keep your vehicle protected and prevent costly engine damage from occurring. How Much Does an Oil Change Actually Cost? Every mechanic has to price their oil changes in a way that helps keep business open. However, you want to ensure that this number does not take advantage of your visit. Here is how much an oil change actually costs your mechanic: Oil Costs : Perhaps the most obvious expense, the mechanic will pay for several quarts of oil to fill your reserve. There are multiple different types of oil that vary in thickness, which can affect your oil change costs. If you take a look at your oil cap, it will tell you which type of oil your engine requires. Labor Cost : Here, you pay for the years of experience and the professional care provided by your oil change technician. You also reap the convenience of having an expert take care of your vehicle. Filter Cost : Your oil filter keeps contaminants out of your engine. These contaminants can wear away at your filter over time, which is why you require regular filter replacements. The cost of your filter may vary slightly depending on your vehicle make, model, trim, and year. Disposing of Used Oil Cost : Part of the hassle of an at-home oil change is navigating the disposal of the old, messy, and contaminated oil. An expert mechanic has the resources and an established process to ethically dispose of old oil. Collectively, what you pay will reflect the cost of the oil change for your mechanic. Even with all of these offerings, oil changes are often reasonably priced—usually running between $40-$70. You can also find oil change coupons to help offset the cost of this service. Transparent Oil Change Prices You won’t find hidden costs here at Chapel Hill Tire. Instead, we keep all of our prices clear and transparent on our services page . The only variance possible in this price is if your vehicle requires a filter or oil that is non-standard or higher in cost. This price includes five quarts of oil, an oil filter change, an air filter check, a fluid levels check, an inspection of your belts and hoses, and a tire air pressure check.
