Every car will eventually need repairs, but the types of problems that show up depend heavily on how many miles the vehicle has traveled. A nearly new car with 15,000 miles is likely to have very different issues than one that has been driven for over 150,000. Knowing what tends to fail at specific mileages helps drivers plan ahead, budget properly, and avoid being blindsided by sudden repair bills. Here is a closer look at the most common car repairs by mileage, with examples of how they appear in everyday models across North America.
Around 15,000 Miles
Even though most cars still feel brand new at this point, early repairs can appear. Brake pads and tires often show noticeable wear depending on driving style. A city driven Honda Civic with stop and go traffic may need front brake pads sooner than expected, while a Toyota Camry on long highway commutes may still be in great shape. Performance models like the BMW 3 Series often come with softer, grippier tires that can wear out in as little as fifteen thousand miles, surprising owners who assumed they would last much longer.
Around 30,000 Miles
At thirty thousand miles, consumables begin to catch up with you. Air filters, cabin filters, and windshield wipers are almost always due for replacement. Spark plugs may also need servicing in smaller turbocharged engines that work harder than naturally aspirated ones. A Ford F 150 with the EcoBoost turbo V6, for example, often sees plug changes around this stage, while a naturally aspirated Toyota Corolla can usually go much longer. These are minor costs but they remind owners that regular upkeep is essential to long term reliability.
Around 45,000 Miles
Brake jobs are one of the most common repairs in this range. Pads and rotors are typically ready for replacement unless the vehicle has been driven primarily on highways. A Camry or Accord often gets its first full brake service at this stage, while heavier SUVs like the Ford Explorer or Toyota Highlander may need them even earlier due to the extra weight. Transmission fluid changes also show up here, particularly in vehicles with continuously variable transmissions like Nissan Altimas, which can be sensitive if fluid is ignored.
Around 60,000 Miles
By sixty thousand miles, more serious wear begins to show. Belts, hoses, and key fluids need to be inspected or replaced. A serpentine belt on a Honda Accord may be due, and cooling hoses on older models often develop cracks. Transmission and differential services are also routine here. Owners who keep up with these repairs avoid bigger problems later. Neglect at this stage can shorten the life of components dramatically.
Around 75,000 Miles
Suspension components begin to lose their edge. Struts and shocks wear down and cause extra bouncing, reduced handling, and uneven tire wear. A Toyota Camry might begin showing floaty handling on the highway, while a Ford F 150 that has hauled heavy loads may feel loose in the rear suspension. Replacing these parts restores stability and safety, though some owners delay the repair until the ride becomes uncomfortable.
Around 90,000 Miles
This is one of the most significant repair milestones. Many engines with timing belts require replacement around ninety thousand miles, often along with the water pump. A Toyota 4Runner or Honda Odyssey with a V6 is a classic example, as both have timing belt service intervals in this range. Ignoring it can lead to catastrophic engine damage if the belt breaks. The repair is expensive but far cheaper than rebuilding an engine, which is why most mechanics insist on taking care of it before failure occurs.
Around 100,000 Miles
At one hundred thousand miles, major tune ups are the order of the day. Spark plugs, ignition coils, and fuel system cleaning often appear on the service list. A Ford F 150 with the 5.4 liter V8 is known for needing new coils around this mileage, often after owners notice rough idling or misfires. Honda Civics and Toyota Corollas also see new plugs installed at this point to keep fuel economy strong. Batteries typically fail around this mileage as well if they have not already been replaced, as most do not last more than five or six years.
Around 110,000 Miles
Electrical components such as alternators and starters often give out beyond the hundred thousand mile mark. A Chevrolet Silverado with dimming headlights or a Honda Accord that cranks slowly in the morning may be telling its owner the alternator or starter is on its way out. These repairs are relatively straightforward compared to major engine or transmission work, but they tend to fail suddenly, making them inconvenient and frustrating when they happen on the road.
Around 120,000 Miles
Exhaust system issues begin to surface in this range. Catalytic converters clog or fail, mufflers rust, and pipes develop leaks. Drivers in the Midwest or Canada where road salt is common often see exhaust failures even earlier. Replacing a catalytic converter on a BMW 3 Series or a Toyota Highlander can be costly, sometimes exceeding a thousand dollars. A failed converter also triggers a check engine light, which can cause the car to fail emission inspections.
Around 130,000 Miles
Power steering systems often start to wear down. In older vehicles with hydraulic systems, pumps and hoses develop leaks, while newer models with electronic steering may see failures in sensors or motors. A Lexus RX from the early 2000s might show heavy steering at low speeds, signaling a tired pump, while a Jeep Cherokee could develop fluid leaks from worn hoses. These issues affect safety, so repairs usually cannot be put off for long.
Around 140,000 Miles
Cooling systems show their age at this stage. Radiators, thermostats, and heater cores are common failures. A Toyota Camry owner may notice coolant leaks from the radiator, while a Ford Escape driver may find the heater blowing cold due to a clogged core. Overheating is a serious risk at this mileage if cooling repairs are ignored, and it can lead to warped heads or blown gaskets that end the life of an otherwise healthy engine.
Around 150,000 Miles
Transmissions become the biggest concern. Vehicles with neglected maintenance are especially at risk. A Nissan Altima with a continuously variable transmission may begin to shudder or slip, while an older Ford F 150 might show rough shifts in its automatic gearbox. These repairs are among the most expensive, sometimes costing more than the value of the car itself. This is often the stage where owners debate whether to repair or replace their vehicle entirely.
Around 160,000 Miles
Wheel bearings and CV joints start to give out after years of wear. A Honda Civic may develop a humming sound from a failing wheel bearing, while a Toyota RAV4 might clunk when turning due to worn CV joints. These repairs are not as catastrophic as transmission failure, but they can make a car unsafe to drive if ignored. Catching them early prevents further damage and ensures smooth operation.
Around 170,000 Miles
Fuel delivery systems often need attention. Fuel pumps, injectors, and sensors such as oxygen or mass airflow sensors commonly fail. A Chevrolet Tahoe may begin stalling due to a weak fuel pump, while a BMW 3 Series might suffer poor fuel economy because of failing oxygen sensors. These repairs can be costly but are essential for keeping the car running properly.
Beyond 180,000 Miles
Once a car passes 180,000 miles, major engine issues become more likely. Oil consumption increases, head gaskets may fail, and valve train wear begins to take its toll. Some engines, like the Toyota Camry’s four cylinder or the Honda Accord’s V6, have proven they can last far beyond this with proper care, sometimes reaching 300,000 miles. Others, particularly high strung turbocharged engines, often show their limits by this stage. At this mileage, repairs may exceed the value of the car, and many owners decide it is time to retire their vehicle.
