What tires are best for a 2003 Toyota Prius? Check out the following tire brands and types.

2003 Toyota Prius Tire Information

Apart from finding the right tire size, there are a couple of other factors to consider when buying Toyota Prius tires like which tire brands you like most and where you drive. When thinking about your driving conditions, consider where you live (mountains vs. city vs. countryside) and the kind of weather can catch you off-guard. (Watch out Tornado Alley!) Many drivers who live in states that experience all four seasons choose to purchase two sets of tires: one for summer and one for winter. Other drivers prefer to purchase one all-season set to limit trips to the tire shop and make sure their vehicle is prepared in the rain, sleet, snow, or sun!

Next, consider your driving style. If you're a diehard off-roader, you have very different tire needs than a highway commuter who doesn't leave the paved path. Visit your local Firestone Complete Auto Care for help selecting the tire that's right for you, or get started by browsing tires that fit your Toyota Prius.

  • How long can I expect my car battery to last?  A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • What is the white, crusty stuff around my Prius’s battery post?  The white, flaky stuff that can build up around your Prius’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time.

If left unaddressed for long enough, it may even cause your battery to prematurely fail.

No matter the mileage, your Prius may need its oil changed ASAP if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the car, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by Toyota if you regularly haul heavy loads, drive in dusty areas, go off-roading a lot, or go at low speeds on long distance trips.

2003 Toyota Prius Oil Change Questions

  • Why is my Toyota Prius oil light illuminated?  Your Toyota Prius oil change reminder light may come on if you're overdue for an oil change. The oil pressure light will typically come on if the oil level in the engine is too low, the oil pump is failing, you have a clogged oil filter, or there's a faulty oil pressure sensor.
  • Can I change my Toyota Prius oil at home?  First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Getting a professional oil change reduces the risk of something going wrong during the service, but also helps your car perform down the road.
  • Why is my Toyota Prius exhaust smoke grayish or blue?  You could have an oil leak and have a case of burning oil. Looks like it’s time for a professional to take a look. The leak could be the result of worn valve seals, fried piston rings, or old cylinder walls.

Replace spark plugs on time or about every 30,000 miles or so.
  • What should I do if I see leaks under my Prius? Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.
  • How often should I clean my Toyota Prius fuel injectors? There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type.

2003 Toyota Prius Suspension Service & Repair

When you first bought your 2003 Toyota Prius, the ride was probably so smooth that you didn’t even think about it! Now, however, things are starting to feel a little rough. Perhaps your Prius feels bouncy, sways to one side, or makes a weird sound when you drive over a speed bump or turn. As soon as you notice that something’s “off” with your 2003 Toyota Prius, bring it in for suspension and steering service. We'll get to the root of the problem and, if your car needs steering and suspension repairs, we'll explain all of your options and the potential cost.

Questions About 2003 Toyota Prius Steering & Suspension

  • Why is my Toyota Prius bouncing excessively? Damaged struts or shocks can't dampen road bumps properly, causing your vehicle to feel like a trampoline after each dip or bump.
  • Why does my Prius tilt forward when I hit the brakes?  When you brake, the forward momentum combined with your vehicle's weight sends a lot of force to the vehicle's front end. A bad suspension can cause all that weight and force to push the front end downward.
  • Does treadwear and tire pressure impact my Prius's steering and suspension?  Keeping your tires properly inflated can help reduce strain on the suspension, and also help you notice when you need new tires. A tire that doesn't have an adequate amount of tread can't grip the road or function as well as the manufacturer intended.

  • Why do I get hot air from my Prius A/C?  An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.
  • What can cause an A/C system leak?  Over the years, the rubber seals and gaskets in your Prius’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.
  • Why does my vehicle have to be moving for my Prius’s A/C to work?  If your A/C only works when the vehicle is moving, there could be a problem with part of your Prius’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

Since the transmission has to translate the precise amount of power for your desired amount of speed, a small transmission issue can put a big dent in your Prius’s performance.

Some technicians would say that between 30,000 and 60,000 miles is a good timeframe for having your Toyota's transmission fluid checked and replaced, but that timeline can vary depending on how your vehicle is used and your manufacturer’s recommendations. The good news is that transmission fluid leaks are affordable to repair and easy to spot.
  • Can transmission fluid leak from my Toyota Prius?  Yes. Toyota Prius transmission fluid can leak over time and potentially cause transmission issues. Worn or damaged seals, a loose or damaged transmission pan, a cracked transmission housing, faulty transmission cooler lines, or an overfilled transmission could cause transmission fluid leaks.
  • Should I avoid driving my Toyota Prius if there is a transmission fluid leak?  You should avoid driving with a transmission fluid leak. Your transmission system relies on transmission fluid to operate properly, and a leak may decrease performance, cause your Prius to overheat, or even lead to transmission failure.
