High Mileage Prius Problems

The Toyota Prius is a popular hybrid car that has been on the market for years. However, as these cars age, they can start to experience high mileage problems. These problems can include decreased fuel economy, increased engine noise, and more frequent repairs.

If you own a high mileage Prius, it’s important to be aware of these potential problems so you can keep your car running smoothly for as long as possible.

If you’re looking at buying a used Toyota Prius, be aware that there may be some high mileage problems to watch out for. The most common issue is with the battery, which can die suddenly and without warning. This can leave you stranded on the side of the road, so it’s important to get a thorough inspection before buying.

Other issues include wear and tear on the brakes and suspension, as well as engine trouble. Be sure to have any used Prius inspected by a qualified mechanic before making your purchase.

What are High Mileage Prius Problems

As with any vehicle, the Toyota Prius will have its share of problems as it gets older. Below are some specific issues that tend to crop up more often on high mileage Prii: 1) diminished battery capacity – as the batteries age, they will lose some of their ability to hold a charge.

This can result in shorter electric-only driving range and less fuel economy. Replacing the batteries is usually the best solution, but can be quite expensive. 2) Engine sludge – due to the unique design of the Prius engine (it runs on a Atkinson cycle which is less efficient than a regular Otto cycle), there is a tendency for oil to break down and turn into sludge more quickly than on other cars.

This can cause all sorts of engine problems, from decreased performance to outright failure. Regular oil changes and using a good quality synthetic oil can help mitigate this issue somewhat.

3) Coolant leaks – again because of the unusual engine design, there are several potential coolant leak points in the Prius engine bay.

These leaks can lead to overheating and serious engine damage if not addressed promptly. Fortunately, most coolant leaks are relatively easy and inexpensive to fix once they’re found.

How Often Do These Problems Occur

While it can vary depending on the person, typically migraines occur around 1-2 times a month. However, there are some people who experience them more or less frequently.

2. Tire Replacement – Tires typically need to be replaced every few years regardless of mileage.

However, if you have a lot of miles on your Prius, you may find yourself replacing them more often. A set of four new tires can cost anywhere from $600-$1,200 depending on the brand and type you choose. 3. Brake Pads/Rotors – The brake pads and rotors on a car typically need to be replaced every 30-60 thousand miles or so depending on driving habits (city vs highway).

A full brake job (pads & rotors) on a Prius can cost around $800-$1,000 at a shop but can be done for much less if you’re handy and do it yourself. 4. Suspension/Shocks – Another common issue with high mileage cars is worn out suspension components like shocks or struts. This usually isn’t too big of a problem on newer cars but can definitely become an issue as a car ages and racks up the miles .

Replacing all 4 shocks/struts on a Prius can cost upwards of $1,500 but can be done for less than half that price if you’re willing to get dirty and do it yourself .


Many Prius owners are reporting problems with their high mileage cars. The most common issues seem to be related to the battery, brakes, and suspension. Some owners have also reported problems with the engine and transmission.

These problems can be expensive to fix, and they may not be covered by warranty.
