The Toughest Jobs for Vehicles, Working on Electric Cars, Why Tires May Ware Down
Term

ASC certified technician

ASC certification is a credential that indicates a technician has been trained and tested to meet certain service standards. It’s meant to give customers confidence in the technician’s diagnostic skills.

Term

intermittent issues

An intermittent issue is a problem that comes and goes. It can be frustrating because it’s hard to prove while you’re testing the car, so the mechanic has to keep narrowing down what might be causing it.

Term

drivability issue

A drivability issue is when the car doesn’t feel right while you’re driving. It might hesitate, run rough, or act weird, and mechanics have to figure out what system is causing it.

Term

wiring diagram

A wiring diagram is like a map of the car’s electrical system. It helps a mechanic trace where wires go so they can figure out where a problem might be happening.

Term

ABS light

That light is for the car’s anti-lock braking system. If it’s flashing or staying on, the system may not be working the way it should.

Term

scan tool

A scan tool is a computer that plugs into the car to read and reset codes. Some cars need that kind of tool after a battery change so everything is set up correctly.

Term

initialization

Initialization is the car’s way of “re-learning” after you change something important. After a battery swap, the car may need to be set up so it charges and monitors the new battery properly.

Term

timing chain

A timing chain helps the engine’s moving parts work together at the right times. If it wears out, the engine can run badly and may cause expensive damage, so replacing it can be a big repair.

Term

timing belt

A timing belt keeps the engine’s valves opening at the correct times. If it fails, the engine can be badly damaged, which is why replacement is often scheduled and can be labor-intensive.

Concept

pull the engine

“Pull the engine” means taking the engine out of the car to reach parts that are too difficult to get to otherwise. It usually takes a lot of labor and costs more than simpler repairs.

Concept

hybrid vehicle

A hybrid car uses a gas engine and an electric system together. Because it has extra electrical parts and a battery, it can be different (and sometimes harder) to repair than a regular gas car.

Concept

high capacity batteries

High-capacity batteries are the big battery packs that store the electricity for hybrids and electric cars. They’re expensive and require extra care to work around, so repairs can be more complicated.

Term

combustion engine

A combustion engine is the typical gas-engine setup that burns fuel to make power. It’s different from an electric motor in how it produces motion.

Term

electric vehicle

An electric vehicle uses a battery and an electric motor to move instead of a gas engine. That means some things you maintain and replace are different from regular cars.

Term

oil to change

Gas cars need oil changes because oil helps protect the engine and keeps it running cool. Electric cars don’t need that same engine-oil routine.

Term

loaded tire

A loaded tire is a tire carrying the car’s weight. When the car is heavier, the tire can wear faster, so tire choice and setup can matter.

Term

electronic ignition

Electronic ignition is how a gas engine makes the spark to ignite fuel. It’s controlled electronically so the spark timing can be more precise.

Term

fuel injection

Fuel injection is a modern way to deliver fuel to the engine using controlled injectors. It helps the engine get the right amount of fuel at the right time.

Term

carburetor

A carburetor is an older way of mixing fuel and air for a gas engine. Newer cars usually use more modern systems that control that mixture more precisely.

Term

adaptive cruise control

Adaptive cruise control is like cruise control, but it can slow down and speed up to keep a safe distance from the car in front. It uses sensors to watch traffic.

Term

parking assist

Parking assist helps you park by using sensors to detect things around the car. It can make parking easier, but it relies on sensors working correctly.

Term

sensors

Sensors are the car’s “measurement tools” that collect data for the computer. More sensors usually means the car can do more things, but it can also mean more parts to diagnose if something goes wrong.

Chrysler LeBaron
Car

Chrysler LeBaron

This is a 1993 Chrysler LeBaron convertible. The issue described is that the car keeps hitting the bottom over bumps even though the shocks test “okay,” which often means the shocks may not be the right type for the car’s weight and suspension setup.

Part

shocks

Shocks are what slow the suspension down when you hit bumps. If the car still drops too far (“bottoms out”), the shocks may not be the right ones for the car’s weight or suspension setup, even if a basic test says they’re fine.

Term

dampening

Dampening is how the shock slows down the up-and-down motion of the suspension. Even if it damps bouncing correctly, it might not hold the car up enough when you hit uneven roads or carry extra weight.

Term

load setting

A shock’s load setting (often tied to its spring/shock calibration and valving) determines how it supports the vehicle’s weight and how it responds to bumps. If a previous replacement used a different load rating—especially on a heavier configuration like a convertible—ride height and bottoming behavior can change.

Part

coil spring

A coil spring is the part that holds the car up and controls how much it compresses. If the spring/shock setup is different from stock, the car may compress too far on bumps.

Term

key fob

A key fob is the remote you use to unlock and start the car without a traditional key. If the car says it can’t detect the fob, moving the fob close to the start button can sometimes help because the car reads it more directly there.

Term

push button

Some cars start with a button instead of a key in the ignition. If the fob battery is low, the car may still be able to read the fob when it’s held right near the button.

Term

transponder

The key fob has a small electronic chip that “checks in” with the car. If the battery is too weak, the car may still be able to communicate with the fob when it’s held close.

Term

programming

Key fobs can require programming (pairing) to the vehicle so the car recognizes that specific fob. If the fob loses its ability to communicate—whether from battery issues or a pairing problem—the car may not unlock or start reliably.

Concept

resale value

Resale value is how much your car might be worth when you sell it later. With electric cars, things like battery condition and newer tech can affect that number.

Term

charge rate

Charge rate means how fast you charge the battery. Charging very fast can make the battery run hotter and may wear it out faster over time.

Term

duty cycle

Duty cycle just means how you use the battery day to day. If you drive in a way that keeps the battery working hard more often, it can wear out sooner.

Term

rotate

Tire rotation means swapping tires to different spots so they wear more evenly. That helps prevent extra noise and helps the tires last longer.

Term

premature wear

Premature wear means the tires are getting worn out sooner than they should. It can happen when tires wear unevenly and aren’t swapped around.

Term

road noise

Road noise is the sound you hear from the tires while driving. If the tread wears unevenly, the tire can make more noise than it should.

Term

brakes

Brakes wear down as you drive. Checking them regularly helps you spot problems early, before they turn into bigger and costlier repairs.

Term

oil the manufacturer

Car makers publish how often you should change the engine oil. The host is saying that even if some guidance suggests very long intervals, they’ve seen oil-related problems when people go too far.

Term

synthetic

Synthetic oil is a higher-tech type of engine oil. It usually lasts longer than regular oil, which is why the host says you can often change it less frequently (like every 5,000 miles) if that matches the vehicle’s needs.

Term

oil filter

The oil filter is like a screen that traps dirt and debris in the engine oil. The host’s point is that you should change the filter when you change the oil, not just the oil, to keep the engine protected.

Honda Ridgeline
Car

Honda Ridgeline

The Honda Ridgeline is a pickup truck that drives more like a car than a traditional truck. The host mentions a 2019 Ridgeline to talk about how often to change oil and why keeping up with maintenance can prevent expensive repairs.

Term

QR code

A QR code is a scannable code that directs you to digital resources, like an online owner’s manual or setup instructions. In modern vehicles, this can replace printed manuals, which is what the host is describing for their truck.

Chevy Traverse
Car

Chevy Traverse

A Chevy Traverse is a family SUV. If you park it for months, the main concern is the battery going dead. You can either use a battery charger/maintainer or disconnect the battery while it’s stored.

Term

battery maintain it

A battery maintainer is a small charger you plug in to keep the battery from running down while the car is parked. It’s useful when you won’t drive the vehicle for a long time.

Term

disconnecting the battery

Disconnecting the battery means you unplug it so the car can’t use any power while it’s parked. This can help prevent the battery from dying, but you have to do it carefully.

Term

controlled climate

A controlled-climate garage means the temperature stays more even instead of getting very cold. Cold weather can drain a car battery faster, so storage strategy changes depending on how warm the garage stays.

Car

2019 Chevy 2500 pickup

This is a 2019 Chevy 2500 pickup truck. Like any vehicle, if it sits for months, the battery can lose charge. Temperature and whether you keep power connected (with a maintainer) matter.

Term

software updating

Just like phones and computers, car systems can get software updates. Updates can fix glitches or improve how the car’s electronics work.

Term

modules of computers

Cars today have several small computers, not just one. Each one controls a different part of the car, and a mechanic can check them to find where the issue is coming from.

Term

anti theft software or device

Anti-theft systems are meant to stop someone from starting the car without the right key. If it acts up, it can sometimes block the car from starting even when you have the correct key.

Term

fault information stored

Cars can remember problems they detect, even if the problem goes away later. A mechanic can read that saved information to help find what happened.

Term

pressurized cap

The radiator cap helps keep the cooling system pressurized. If it’s not the right cap or it’s not holding pressure, the engine can overheat faster, so it’s safer to wait for a replacement.

Term

reservoir flip top caps

Some cooling systems use a non-pressure “flip-top” style cap on the coolant reservoir, which behaves differently than a pressure-holding radiator cap. The host’s point is that not all caps have the same safety implications for driving.

Jeep Renegade
Car

Jeep Renegade

A Jeep Renegade is a small SUV. If its tires wear out way too fast, it often means something like the wheel alignment isn’t set correctly.

Term

tire rotation

Tire rotation means swapping the tires to different wheel spots. That helps them wear more evenly instead of one set wearing out early.

Brand

Bridgestone 75,000 mile tires

Bridgestone makes tires. The “75,000 mile” part is the advertised expected life, so wearing out in 20,000 miles suggests something is wrong.

Term

wheel alignment

Wheel alignment is how straight your wheels are pointed. If it’s off, tires can scrub and wear out much faster than they should.

Term

air filter elements

The air filter element is the part that traps dirt before air goes into the engine. A clean one helps the engine run properly.

Term

OE level quality

OE level quality means the replacement part is made to similar standards as the original part from the factory. The host is saying not all filters are the same, so choose a higher-quality one.

Term

cabin filter

A cabin filter cleans the air that comes into the car’s heating and air-conditioning system. If it’s dirty, you’ll breathe more dust and pollen inside the cabin.

Term

engine air filter

The engine air filter is like a screen that keeps dirt out of the air going into the engine. If it gets clogged, the engine can’t breathe as well.

Term

original equipment

Original equipment parts are the same kind of parts the car maker used when the vehicle was new. They’re chosen to fit correctly and work the way the car was designed to.

Chevrolet Silverado
Car

Chevrolet Silverado

The Chevrolet Silverado is a popular full-size pickup. The “5.3” means it has a 5.3-liter V8 engine, and this question is about a problem that happened in that engine.

Term

864 interrupter

An interrupter is a gadget meant to change how the engine control system behaves. Here, the listener is asking if it can keep the engine from shutting down cylinders and instead run on all eight.

Term

lifter

A lifter is a small engine part that helps open and close the engine’s valves. If it doesn’t work right, the engine can run poorly and in worst cases get damaged.

Term

fuel management system

This is the engine computer that decides how much fuel to use. In some cars, it can also turn off some cylinders when you’re cruising to save fuel.

Term

shut certain cylinders off

Some cars can temporarily stop using a few cylinders while you’re cruising. That saves fuel, but it can also add extra wear on parts that have to switch cylinders on and off.

Term

cylinder head

The cylinder head is the top part of the engine where the valves and important internal passages live. If something goes wrong inside one cylinder, it can damage this area.

Term

oil will absorb moisture

Even if you don’t drive much, oil can pick up water over time. That water can turn into condensation and make the oil less effective at protecting the engine.

Term

condensation

Condensation is basically water that collects inside the engine. If the car doesn’t get driven enough to fully warm up, that water can build up.

Term

oil change

An oil change refreshes the oil that lubricates the engine. Old oil can get dirty and less effective at protecting the engine.

Term

original tires

Original tires are the tires that were installed when the car was new. Over many years, the rubber can dry out and get less grippy and more likely to wear badly.
