The regular Toyota Prius is the most efficient car you can buy that doesn't have to be plugged into an electrical outlet. It gets an impressive 44 mpg overall in our testing--with plenty of room for five, a big flexible hatchback, a comfortable ride, and very secure handling. If there's a knock on the Prius, it isn't engaging to drive, feels underpowered and is loud when you ask for max power.

Road Test

The regular Toyota Prius is the most efficient car you can buy that doesn't have to be plugged into an electrical outlet. It gets an impressive 44 mpg overall in our testing--with plenty of room for five, a big flexible hatchback, a comfortable ride, and very secure handling. If there's a knock on the Prius, it isn't engaging to drive, feels underpowered and is loud when you ask for max power.

Getting the Prius Plug-in version includes a bigger battery that can be charged from any wall outlet, allowing the car to drive more on electricity and less on gas. A full charge gives an electric range of about 12 miles. While the battery was charged, we measured 67 mpg overall in combined city and highway driving.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2012 Toyota Prius owners. The owner comments describe problems respondents experienced with this vehicle.

In-car Electronics

CD or DVD players, radio, speakers, GPS, communication system (e.g., OnStar), display screen freezes or goes blank, phone pairing (e.g. Bluetooth), voice control commands, steering wheel controls, portable music device interface (e.g., iPod/MP3 player), backup or other camera/sensors.

What Owners Say

Backup or other camera/sensors

"Whole Nav / Radio system had to be replaced at 53246 miles"

Anonymous, FL (2012 Toyota Prius Three 1.8-L 4 Cyl hybrid)

"As with the GPS, the Backup camera worked intermittently. I solved the problem by replacing the MFD myself with a used unit"

Paul S., QC (2012 Toyota Prius 1.8-L 4 Cyl hybrid)
CD player

"A CD started to "skip" or "stutter" so I pushed the eject button. The door opened but the CD failed to eject. The door would not close, and because of the way it was designed, my radio and, more importantly, my GPS and back-up camera screen, were not accessible! My service advisor at the dealership was able to get the CD to eject, thus restoring the other systems. Had he not been able to eject the CD, installation of a replacement unit would have cost me over $1000!"

Pamela U., NJ (2012 Toyota Prius Four 1.8-L 4 Cyl hybrid)
Display screen difficult to see

"Cannot see back-up camera images in bright sunlight. Camera "eye" doesn't project clear image in rainy or snowy conditions. Water clings to the "eye," projecting an unclear image. Wider angle view would be helpful in busy parking lot -- have almost hit pedestrians when my vehicle started to move because they were not picked up be my camera. ALSO -- difficult to estimate distances. My screen has no "guidelines" as I've seen in other models. Those lines are essential!"

Pamela U., NJ (2012 Toyota Prius Four 1.8-L 4 Cyl hybrid)

"Esp. in the daytime"

Gary A., FL (2012 Toyota Prius Five 1.8-L 4 Cyl hybrid)

"I think they just used inferior display screen, It is not crisp. Also the screen is impossible to see if the headlights are on with sun glasses, light when its bright out even though I have learn how to keep the display in a bright mode no matter"

Carl F., NY (2012 Toyota Prius Plug-in Plug-in Hybrid)
Display screen freezes up

"Sometimes when the phone is disconnected the car can not be put into gear without turning the car off and back on. This is troubling if you are at an intersection. t"

Chuck S., CA (2012 Toyota Prius 1.8-L 4 Cyl hybrid)

"Screen displays, Maintenance Required when maintenance is needed. Maintenance is completed by our mechanic. He can't reset the display, despite following Toyota's instructions. Go to the dealership and they do reset it, but even there it is not a simple operation and takes them 20 minutes. Very inconvenient for us because the dealership is an hour's round trip from our home."

Stephen P., NY (2012 Toyota Prius Plug-in 1.8-L 4 Cyl plug-in hybrid)

"Samsung devices and Entunes not working; Toyota unwilling to change out module even though an extended warranty was purchased at the time of purchase. Multiple times at dealership only to have them tell me it is my phone not their system. My device works with many other blue tooth accessories and don't have the same problem as I do with Entunes. In addition with out Entunes/ the BT connection still freezes so it does not appear to be with Entunes. Multiple tickets were open and truly disappointed with Toyota about this ordeal especially since I purchased the Toyota extended warranty for this very reason. I suspected more technical issues with the radio console than i did with the foundation that the Prius brand has."

Marilee K., IL (2012 Toyota Prius Four 1.8-L 4 Cyl hybrid)
Display screen goes blank

"Problem with the radio extension that affected the gps, back up camera"

Anonymous, NY (2012 Toyota Prius Three 1.8-L 4 Cyl hybrid)

"The odometer, etc screen is blank and who cost over $2,00 to repair"

George V., CA (2012 Toyota Prius Plug-in 1.8-L 4 Cyl plug-in hybrid )

"The right half of the screen is no longer functional, which displayed the odometer and other info."

George V., CA (2012 Toyota Prius Plug-in 1.8-L 4 Cyl plug-in hybrid)

"Screen went blank - unable to use any functions - phone, navigation, radio. Dealer had to replace entire unit after two tries of not ordering correct parts. Cost covered under separate extended warranty"

Anonymous, NM (2012 Toyota Prius Three Hybrid)

"There was a short in the multifunctional display screen resulting in the draining of the 12v battery. The problem initially manifested itself in the display being delayed but ultimately led to the car not starting"

Anonymous, VA (2012 Toyota Prius Hybrid)
External music device interface (e.g., smart phone, MP3 player)

"The music autoplays whenever I connect using the USB port. The dealer has looked at it several time with no resolution"

Larry C., WA (2012 Toyota Prius Four 1.8-L 4 Cyl hybrid)

"smart phone keypad does not always display correctly on instrument panel's screen"

Anonymous, MN (2012 Toyota Prius 1.8-L 4 Cyl hybrid)

"Sound system can't be connected to a phone to play music from my phone or take calls. They said it would cost $2000 to fix, so i didn't fix it."

Eve A., CA (2012 Toyota Prius Plug-in 1.8-L 4 Cyl plug-in hybrid)

"Doesn't always sync with iphone. Music control from dash doesn't always work. I ned to turn iphone on, start music playing, then connect with USB for the music to play. This may be an iphone problem, and not the car. My old iphone didn't do this"

Anonymous, OH (2012 Toyota Prius Five Hybrid)

"Sometimes skips, like an old LP record"

Anonymous, AR (2012 Toyota Prius Four Hybrid)

"Does not interact well with my iphone. Often difficult or impossible to get music to play properly. Sometimes have to "reboot" the car by shutting off the engine & restarting to get the system to work"

Robert P., NY (2012 Toyota Prius Four Hybrid)

"Frequent trouble linking Android phone to Bluetooth"

Jacob M., IL (2012 Toyota Prius Four Hybrid)

"If ipod connects, it will stop/start/disconnect/connect frequently. iPod works in all other vehicles (several rental cars, family/friend cars). Only will not work correctly in Prius. All other devices tried interface OK"

Anonymous, PA (2012 Toyota Prius Three Hybrid)

"Car entertainment system can't/won't recognize iPhone and renders on screen interaction useless"

Christopher F., MA (2012 Toyota Prius Three Hybrid)

"Using my iPhone ITunes music when connected via USB, parts of songs are lost. It does not happen if I connect via Bluetooth."

Anonymous, OH (2012 Toyota Prius Five 1.8-L 4 Cyl hybrid)

"Doesn't always pair with the device, sometimes have to disconnect the device and/or restart the car to make it pair. Also the car controls do not control the device very well."

Robert P., NY (2012 Toyota Prius Four 1.8-L 4 Cyl hybrid)
In-dash navigation system (GPS)

"GPS system failed. Replacement did not lower radio volume when giving directions and therefore could not be heard. Dealership could not fix this problem but raised the volume of the GPS so that it could be heard over the radio. Then after the car battery died and was replaced, the GPS was not properly reset, and I was unable to re-enter destination addresses. That was supposedly done today, but I don't know for sure if this latest problem is resolved"

Susan D., FL (2012 Toyota Prius 1.8-L 4 Cyl hybrid)

"It is difficult to use, it doesn't give you a lot of places to look for(esp. while moving), it doesn't have to say "recalculating" & it is cost prohibitive to update"

Gary A., FL (2012 Toyota Prius Five 1.8-L 4 Cyl hybrid)

"GPS, Bluetooth and backup camera worked intermittently. The worked more often in cold temperatures. Toyota dealer wanted $3,000 to replace the MFD but said they would not guarantee the work. I found a used one for $175 and replaced it myself with the help of YouTube videos. Works fine now"

Paul S., QC (2012 Toyota Prius 1.8-L 4 Cyl hybrid)

"Slow and cumbersome. They sacrificed efficiency for fancier visuals. Much inferior to the last Prius I owned. A classic case of needing to change just for the new model year. "New and improved gps" is virtually unusable except for the nugatory entertainment value of the pretty visuals"

Anonymous, CA (2012 Toyota Prius 1.8-L 4 Cyl hybrid)

"1) Touch screen often does not correctly correspond with gps"

"The whole radio/navigation system/entune system just quit working"

Sarah V., MN (2012 Toyota Prius Plug-in Plug-in Hybrid)

"GPS has given very bad/ erroneous routing guidance in congested areas, is slow to give turn warnings. Screen is ridiculously hard to see when I wear sunglasses or polarizing lens. I have resorted to using a 10 year old Magellan GPS near the steering"

Carl F., NY (2012 Toyota Prius Plug-in Plug-in Hybrid)

"On Interstate, many 'straight miles to go', GPS tells us to 'turn left', several times of course. Took to different dealer (non-leasing) - They checked and updated the GPS. Problem has not occurred since"

Anonymous, FL (2012 Toyota Prius Three Hybrid)

"frequently locks up during navigation. only reset is to power down entire car. even after reset, often claims known addresses to be "not navigable". awful software. loses GPS lock without warning"

Joseph G., VA (2012 Toyota Prius Five Hybrid)

"In dash screen can't handle complicated GPS (in city). Constantly freezes up and only fix is to completely turn off car and restart"

Christopher F., MA (2012 Toyota Prius Three Hybrid)

"GPS failed and was replaced by the dealership with a refurbished unit. The replacement unit was incorrectly set and would not let me input some local addresses. The dealership corrected that problem when I brought it back and complained. The replacement unit also did not lower the radio volume for navigation directions, which meant that the directions could not be understood. When I complained, the dealership raised the GPS audio volume. Now, although this function is not working as it's supposed to, the GPS is at least usable."

Susan D., FL (2012 Toyota Prius 1.8-L 4 Cyl hybrid)

"It never works consistently, and it's a pain to keep setting the phone up to the system. (Though this may be more of a reflection on the owner than that car's system,)"

Sally G., IL (2012 Toyota Prius Hybrid)

"I have a Samsung 7 Galaxy phone, it will connect via Bluetooth to my Prius, but typically after a short time, it will disconnect. My Prius Navigation/Entertainment/GPS system shows that Bluetooth if off, and I can not turn it back on. My wife's IPhone 7 does not have this issue. I did go to the Toyota web site, downloaded to a Memory Stick, an update for my Navigation/Entertainment/GPS system, which is the most current one they have on their site. It seemed to greatly improve my Bluetooth pairing problem for a few weeks, but now it is as bad as it has ever been. From reviewing online forums, some other Prius owners who have this same problem have gone to the Toyota dealer, though the other Prius owners have stated that their Toyota dealers did not state that they would fix this problem, rather they would update all firmware for the Prius. I love my Prius, but I hate this issue between the Bluetooth pairing with my Samsung 7 Galaxy Android phone."

Katherine B., CA (2012 Toyota Prius Three 1.8-L 4 Cyl hybrid)

"My handsfree phone part would not pair with my phone and when you went to the display to try and turn on Bluetooth, the screen would not respond. The dealer had to replace the same part 3 times. The problem seems fixed although on a time or two I've tried to use my handsfree phone and the same thing happened. If I turned my car off and back on then waited for a mile or two the handsfree phone would work, The dealer and Toyota rep indicated this is a part problem. It was most frustrating. I am very disappointed in Toyota."

"I purchased a new iPhone X and while the display indicates it has paired with an iPhone, it shows that it does not connect to the phone when I try to access Entune apps like weather, movies, fuel prices, etc. this issue started when I bought the IPhone. Prior to that the weather app stopped working regularly (I had a Moto that did sync with the car). The app stopped updating daily, and while I can access these apps on the phone, they do not connect to the car (with iPhone). I called Toyota about the weather app, but they saw no issues with it (someone in Texas) and still does not update. I'll bring it to the dealer s attention the next time I take it in for oil service.

"Discussed this in the previous section - brakes done at 60,000 miles, then again at 90,000 miles, then discovered the emergency brake failure after that - emergency brake peddal went all the way to the firewall and would not keep the car from rolling. Back to the dealer for caliper replacement. Refused to accept the vehicle because now the primary brake peddal went all the way to the firewall. Dealer adjusted brakes but declined any explanation as to why it wasn't fixed correctly the first time around. Requested a conversation with the dealer's owner to make them aware of the way the service department was not behaving - I'm still waiting for that conversation. Was going to trade the 2012 when the 2020's come out. Now I'm not so sure. I've lost confidence in the dealer (their service department). I've hear similar comments (unsolicited) from others in the community. My primary question is - if the original brakes lasted to 60K, and I'm assuming the work was done with OEM parts, repacement needed to be done again 30,000 miles later. And why, for no apparent reason, the emergency brake failure."

"Deteriorating seal around sunroof. On-line research indicates that this is a problem with these sunroofs in northern tier states -- something about the weather up here. The repair involves replacing most or all of the sunroof -- they cannot simply replace the gasket/seal. The cost for this -- just the parts and not including labor -- when I last checked with my dealership in May of 2018 was $1731. So far we are just living with it, but it took a big hit this winter 2018-19 which was harsh in New England. So we might have to get it repaired. Toyota does not look at this as a product defect. The problem started showing up in the winter of 2017, when the car was 5 years old, so I guess they view it as normal wear and tear. But the fact that this has been a problem in northern areas of the US indicates to me that this is a design flaw and one they should take at least part responsibility for."

When it is replaced, the last one lasted for less than 20,000 miles. I didn't get the last one replaced because of the $900 non insured cost. Emissions are not covered in the after market insurance that I bought from the dealer, for a cost of $2000. I was not told of the emission system exclusion until the filter was replaced. I was only told that the insurance was the best I could get, and that it covered from bumper to bumper."

Oil leaks

"2012 Toyota Prius Model 2, VIN# JTDKN3DU4C1532777 If you have a Toyota Prius please be aware! Toyota Vacaville's standard charge to fix a small timing cover oil leak is $2295.00 !! I changed my own oil in Oct.2016, no oil leak noted. I brought it in Dec. 2016 for a air bag recall, had general vehicle inspection done. Inspection revealed small timing cover oil leak. I inspected it at home and found some dirt\oil residue near the timing cover, but no so called leak. I found no oil accumulation"

William C., CA (2012 Toyota Prius Two 1.8-L 4 Cyl hybrid)

"Oil leak originally estimated by dealer at over $2000 was reluctantly covered by Toyota via a recently expired extended warranty. Final bill covered by Toyota was $1200. I hate to think the dealer would have charged me $2000, but would accept $1200 from Toyota"

Anonymous, OR (2012 Toyota Prius Three 1.8-L 4 Cyl hybrid)

"I did not notice this leak, it was discovered during a check while getting oil service. It was a leak associated with the timing chain cover. Cost was covered with platinum extended coverage, the cost of which was less than the repair cost."

Loren P., GA (2012 Toyota Prius Hybrid)

"The compressor was much more expensive than compared to other vehicles. I spend around $3000 for the repairs and that was after calling around to numerous mechanics. Most mechanics wouldn't touch it because it was a hybrid."
