Still, all older used cars require maintenance and repairs, usually more than newer ones, so this has to be factored into any buying decision as well.

So here, we'll cover this older Prius' pros and cons, its general reliability reputation along with specific mechanical issues to have checked out before purchase, plus a feature overview of the vehicle from when it came out in 2011.

But first, and very importantly ...

Things To Do When Considering An "Older" Vehicle

Locate Lower Mileage Vehicles: They are certainly out there to be found with careful and patient shopping. Be willing to drive a distance if you have to.

Vehicle History and Maintenance: Ask for the vehicle history report (CarFax or AutoCheck) as well as documented maintenance and repair records. If not provided by the Dealer or private seller, it's best to move on.

Pre-Purchase Inspection: Have the vehicle independently inspected before making a final decision. This usually will cost in the $150-$200 range but is well worth it given the potentially thousands in savings over the long term.

2011 Toyota Prius Cons

Driving Experience: Some drivers find the driving experience of the Prius to be less engaging, with a focus on economy over performance. It may not be as enjoyable to drive as some other cars.

Ride Comfort: The ride quality can be described as smooth but not as plush as in some larger sedans, which might be a consideration for those who prioritize comfort.

Visibility: Some drivers find the rear visibility of the Prius to be limited due to its distinctive rear window design.

Cargo Space (in some models): While the Prius offers good cargo space in the hatchback version, the Prius Plug-In and Prius C models have less cargo space due to their battery configurations.

Cost of Battery Replacement: While the hybrid battery is generally durable, if it needs to be replaced, it can be expensive. However, many Prius owners find that they don't need to replace the battery during their ownership.

Noise Levels: Some drivers and passengers may find that road and wind noise is more noticeable in the Prius compared to other vehicles.

2011 Toyota Prius Reliability

The 2011 Prius has several reliability points that have contributed to its positive reputation among owners and automotive experts:

Longevity: Many Prius owners report that their vehicles have high mileage and continue to run well after many years of use. The hybrid system is designed to be durable, and with proper maintenance, the Prius can provide many years of reliable service.

Low Operating Costs: The Prius tends to have lower maintenance and operating costs compared to some other vehicles. The regenerative braking system and the fact that it often requires less frequent oil changes contribute to reduced long-term wear and expenses.

Dependable Engine: The 1.8-liter gasoline engine used in the 2011 Prius is known for its reliability, and it's been used in various Toyota models.

Solid Build Quality: Toyota is generally recognized for its build quality and attention to detail, which contributes to the reliability of the Prius.

Safety Features: The 2011 Prius often came equipped with advanced safety features, such as antilock brakes, stability control, and multiple airbags, which contribute to the overall safety and reliability of the vehicle.

It's important to note that while the 2011 Prius has a strong overall reputation for reliability, individual experiences can vary based on factors such as maintenance regularity, the promptness of repairs, and the driving conditions and habits of previous owners.

2011 Toyota Prius Mechanical Problem Watchlist:

Like all cars, the 2011 Prius experienced mechanical issues over time. Common mechanical issues reported by owners and mechanics that should be checked for before purchase include:

Hybrid Battery Issues: While the hybrid batteries in the Prius are known for their durability, they can degrade over time. Some owners may experience reduced battery capacity, which can lead to decreased fuel efficiency. In some cases, the hybrid battery may need to be replaced, which can be a costly repair.

Inverter Failure: The inverter is a critical component of the hybrid system. In some cases, it can fail or experience issues, leading to drivability problems and the need for costly repairs.

Brake Actuator Problems: Some Prius owners have reported issues with the brake actuator, which can cause issues with the regenerative braking system and ABS (Anti-lock Braking System).

Coolant Pump Failures: The electric water pump and inverter coolant pump can fail, which can result in overheating and potential damage to the hybrid system.

Engine Oil Consumption: Some Prius owners have reported higher-than-normal engine oil consumption. It's important to monitor the oil level and address any leaks or consumption issues promptly.

Excessive Oil Leaks: Oil leaks can occur from various sources, including the valve cover gasket, oil cooler pipe, and oil pan gasket. It's essential to address oil leaks to prevent engine damage.

Suspension and Steering Issues: Some owners have experienced problems with the suspension components, such as the struts, ball joints, and control arms. These issues can result in handling and ride quality problems.

Transmission Issues: While the Prius uses a continuously variable transmission (CVT), which is generally reliable, some owners have reported transmission problems, including noise or unusual behavior.

Coolant Leaks: Coolant leaks can occur from various points in the cooling system, and addressing them promptly is important to prevent overheating.

It's important to note that while these issues have been reported by some owners, many 2011 Prius vehicles continue to operate reliably without experiencing these problems. Regular maintenance and timely servicing are crucial for preventing and addressing mechanical issues.

2011 Toyota Prius Overview

As the hybrid market has evolved and heated up considerably in recent years, one thing hasn't changed: the Toyota Prius remains king of the hill with its best-in-class fuel economy, versatile and space-efficient cabin, comfortable ride, high-tech feature offerings, solid build quality and reasonable pricing.

If anything, this Prius is even better following the previous year's (2010) redesign which made aerodynamic revisions to further reduce drag while also giving the car a sleeker and sportier look.

The gas engine size was increased and the electric motor was also strengthened, resulting in both additional power and still better gas mileage performance, with a combined city/highway EPA rating of 50 mpg, simply tops in the conventional hybrid segment. Handling agility was also enhanced thanks to a new suspension tuning and improved electric steering.

The 2011 Prius also offers a wide range of personal customization based on individual preferences. It can come as a fairly basic but versatile utility hatchback or be equipped like a small luxury sedan. Indeed, upper level models can sport such premium and high-tech features as heated leather seats, navigation, an automated parallel-parking system, a solar-powered sunroof (for interior ventilation when parked), a pre-collision system which tightens the seatbelts and applies the brakes if an imminent crash is detected, a lane-departure warning system and adaptive cruise control.

Trims, Standard Features And Options:

The 2011 Toyota Prius is offered in five trims: simply named Prius I, Prius II, Prius III, Prius IV and Prius V.

Standard features on the Prius I include power windows, power mirrors, power doorlocks, 15-inch steel wheels, a height-adjustable driver seat, a tilt/telescoping steering wheel and a 60/40-split-folding rear seat, while the Prius II adds cruise control, keyless entry/ignition, 15-inch alloy wheels, automatic headlights, heated exterior mirrors and a 6-speaker audio system with a CD player and an auxiliary audio jack.

Moving up to the Prius III adds Bluetooth as well as an 8-speaker JBL audio system with a 6-disc CD changer, while the Prius IV goes on to add leather upholstery, heated front seats, exterior locking buttons for keyless entry, an auto-dimming mirror and driver lumbar adjustment. The top-of-the-line Prius V then adds foglamps, LED headlamps with auto-leveling and washers, and 17-inch alloy wheels.

The optional Navigation package is available on all models except the Prius I and II and includes voice-activated touchscreen navigation, a rearview camera, a 4-disc CD changer (instead of the 6-disc), Bluetooth music streaming and an iPod/USB audio interface. A Solar Roof package can then be added to the Navigation package and features a sunroof with a solar-powered ventilation system and remote-activated air-conditioning for cooling the cabin before entering.

There's also an Advanced Technology package offered on the Prius V which includes everything in the Navigation package, automated self parking, a pre-collision alert system, a lane departure warning system and adaptive cruise control.

Engines, Powertrain And Gas Mileage:

Powering all 2011 Prius models is a combination of a 1.8-liter four-cylinder gas engine with two electric motor/generators. The total output is 134-horsepower, transferred by a specialized continuously variable transmission (CVT).

Gas mileage performance is outstanding with an EPA-estimate of 51 mpg city, 48 mpg on the highway and 50 mpg in combined driving.


Standard safety features across the board on all 2011 Toyota Prius models include traction and stability control, antilock disc brakes (ABS), front side airbags, a driver knee airbag and side curtain airbags. In addition, a pre-collision warning system and a lane-departure warning system are available options on upper level models.


2011 Toyota Prius interior

The 2011 Prius' cabin is attractive, roomy and user-friendly. The protruding "floating console", while perhaps busy looking to some, is well laid out, easy to see and use, and also offers an underneath storage tray. A particularly convenient feature is a digital instrument panel display of audio, temperature and trip computer information by touching these controls on the steering wheel.

The overall interior has been thoughtfully designed to maximize space and versatility, while the seating is both comfortable and supportive, front and rear. There's ample space in the backseat and the hatchback body style allows for more cargo room than most traditional midsize sedans.


The driving quality of the 2011 Toyota Prius is not engineered to be particularly spirited, but as a gas-sipping hybrid is quite competent, secure and agile enough. Most drivers will likely be satisfied with its acceleration as well as its helpful four driving modes (Normal, Eco, Power and EV) which allow the driver to select the best powertrain configuration depending on the situation. Eco is uninspiring but gets the best gas mileage. Power is more upbeat for driving up hills or entering highways, while EV eliminates the gas engine in speeds of up to 25 mph when the battery is at least half-charged.
