3 Reasons To Steer Clear Of A 2010-2013 Toyota Prius

As a Prius owner and fan, my goal is to inform anyone who is looking for the right car. Take a look at my 3 reasons not to get a Generation 3 Prius.

I have owned, driven, and fixed a plethora of Prius over the years. As someone who has battled all the problems in the trenches, I have learned a thing or two about what ones are good and what ones to stay away from.

I can also tell you if you are looking to buy what to look for. Here are my three reasons to not buy a 2010-2013 Toyota Prius.

Reason Number One: Headgasket Failure
The generation 3 Prius was a complete redesign starting in 2010. Everything about it was new, including the larger 1.8L all-aluminum engine.

Owners loved these cars, at first. Then the issues started rolling in. The first significant problem people began to encounter was a failing head gasket. If you have not read my other article on knowing if your head gasket is failing, read it here.

Head gasket failure is an expensive repair. Most of the time, people let it go too long and end up bending a connecting rod; at that point, you are better off installing a new engine.

2010 Toyota Prius Bad Head Gasket

After doing multiple head gasket repairs on these cars, I can tell you if you do not catch it early, plan to trade the vehicle in or plan to put an engine in it.

If you can get a car with a bad head gasket for cheap enough and clean, it could be worth your time to have it repaired. Many generation 3 owners have reported 50 to 60 miles per gallon on a good working car, which could be worth it.

Costs for an engine swap or gasket repair usually range in the $2500 to $5000 range, something to consider when purchasing.

Reason Number Two: Inverter Failure
To be fair, Toyota did their best to recall any faulty inverter, but unlike Pokemon, they did not catch them all. Inverters still are failing, and do not expect the repair to be cheap.

2012 Toyota Prius White A new OE inverter can run you well over $2000, not including diag time or labor to install. Refurbished units from other hybrid places are around $650 before install.

Not a cheap repair, and what is worse, there are no warning signs as to when it could fail. Buyer beware.

Reason Number 3: Ridiculous Maintenance
Two things that grind my gears on Gen 3 Prius are the EGR system that always gets plugged up and the electric water pump.

I understand why the components are there, but honestly, is a regular water pump putting that much additional drag on the engine? Sure, an electric water pump can run when the car is off, but when these things fail, you are really stranded.

2010 Toyota Prius Water Pump

New pumps can cost around $650 to have replaced, and that does not include your tow. So, what about the EGR system? Glad you asked.

The EGR system is there to help lower tailpipe emissions which translates into a nightmare. When the exhaust is pushed back into the intake, it carries with it tiny bits of carbon.

These carbon bits get hung up in the cooler and all the tiny ports inside the intake manifold. The carbon builds upon itself and becomes a hardened nightmare to clean. Not to mention that you have to clean it, or it will help contribute to a faster-failing head gasket.

Unfortunately, we will always have carbon build-up as a by-product of the exhaust fumes getting pumped out through our exhaust systems. So, plan on spending a few hundred bucks every 90,000 miles or so to have the system cleaned out thoroughly.

Conclusion
Are Gen 3 Prius bad cars? Not necessarily; they can be pretty good and reliable if all the issues are dealt with and the vehicle has been well maintained. If the EGR is cleaned out regularly, oil changes are done on time, and any open recalls have been taken care of, these cars are pretty good.

As I stated earlier, if you can find a clean one with some issues and get it for cheap, it is worth the investment. But to buy a Gen 3 in an unknown condition is financial suicide.

I have a 2012 Prius V I bought new. EGR failed just having got off a highway on a Sunday on a trip. Had to tow to a local dealer and arrange a fix. Just under 100,000 miles then and Toyota covered it. Last year, at about 150,000 miles my check engine light came on and my local dealer told me it was the head gasket and needed full engine replacement. I have my car serviced at this dealer at the recommended intervals and it had never come up. I opted for a 75,000 mile engine hoping to keep the car as long as possible. Only other major repair was one set of brakes this year at about 180,000 miles. Overall maintenance costs have been low. I have had the regular cleanouts mentioned. Wished I had known about these problems sooner, but still holding on to the car as parts I can see are aging well and so far other than those known problems it has been great for my uses.

I am so glad that we purchased our 2009 Toyota Prius. Someone later in 2009 was telling me that I should have waited for the 2010... that was obviously wrong advice.

Our car has been great; very few problems. No oil burning issues, no head gadget issues, no inverter problems..

After reading this article, I wonder WHY designers mess with something that is successful and working. This unfortunately happens to other cars all the time....

Seems like the best way to buy a car is wait a couple years to see if it's vetted.....

Just bought a 2013 Prius for my fought less than a year ago. Already, the Toyota service said it's not worth replacing the engine or fixing the head gasket due to the mileage. What I don't understand is why isn't there a recall with so many cars affected. Next time, I'll do my research on used cars.

Hi Peter, just curious if you or anyone else has data on these issues for the Toyota Auris hybrid/Lexus Ct200h of similar years since they share the same hybrid system? For some reason it tends to be publicized as a Prius problem. I've heard inverter problems regarding the Auris hybrid, but no one seems to report on the CT200h, so I'm wondering if there's a lack of data there, or that they're not really exactly the same, with some tweaks by Toyota/Lexus?

Alex (not verified)    August 16, 2021 - 1:42PM

Inverter warranty was extended to 15 years, I had mine done no charge. Efr hasn’t plugged for me either, and the head gasket issues were 2010/2011 for the most part

Mines a 2012 with 175k

Lack of accountability by Toyota is four. We have a pearl white 2010 Prius with catastrophic paint failure. All other Toyota models with this paint color were recalled. BUT NOT THE PRIUS. Why is this?

MiA (not verified)    October 4, 2021 - 11:42AM

The issue is way worse than this article leads you to believe not to mention covers many more Prius Years and models. If you are immunocompromised this can be a HUGE health risk. As a matter of fact court papers just hit the court on Sept 22 Beetle vs Toyota for anyone interested. Toyota hid the issue so therefore there were never recalls on the HVAC system. I for one being deathly allergic to mold and immunocompromised with an elderly father who also drives the car I would have NEVER even considered the car. Toyota has potentially put many people in harm's way over profits. It's not like a faulty switch or electrical issue that can just be switched having no impact on ones health. This is a whole other level of corporate greed and negligence.

Your article is a total nonsense. As a taxi driver, most of our fleet consists of Prius and Prius v models 2012 - 2018. Prius that I drive has 426k miles and I am really squeezing everything I can out of it. No major issues to report. Average other taxi mileage is about 300k. Average engine replace for rebuild is $1,700 with labor included. In conclusion, Prius 2012-2018 is a God of hybrids!

The 2010s burn oil. If you dont know and you drive without oil you will blow a head gasket. They fixed the problem from 2013 on. The Third Gen Prius is the best and most reliable. I have 3 currently. 2011 (214k burns oil), 2013 (378k!!!! original everything does not burn oil), 2014 (330k does not burn oil in 15k mile intervals bt changes - original battery and engine). I have blown an engine of a 2010 with 320k miles. As long as you and the previous owner don't let the car run out of oil and overheat it will last forever.

I happen to disagree with you on your review of the Priuses, I own a 2010 Prius which has been nothing but a fantastic vehicle! It is a cherished member for it's reliability with really very little maintenance, even with 113,000 mi on it! All I have done is change the oil every 5,000 miles and put tires on it, and of course change the air filters. I have six friends with the same stretch of years in your review and all of them feel the same way I do about their Priuses! Shame on you for condemning our cars to the scrap heap!

I have a 2011 Prius bought new and has 247,000 miles. I do all tune upsHad local high school auto shop clean the EGR valve. I also had them replace the PCV valve which over time was stuck in the open position causing oil usage. Car runs great.

Priusly (not verified)    December 21, 2021 - 6:03AM

I had to replace my Inverter at 120k, the parts/labor were free because it was covered by a service bulletin up to 150k. Otherwise, it’s been a super solid vehicle.

Randy (not verified)    December 22, 2021 - 7:50AM

I have an 09 prius. Swapped out the battery and the car runs fine but the red triangle is still on and the engine never shuts off. Still getting about 40 miles per gallon though.

Terry Goodpaster (not verified)    December 29, 2021 - 9:07PM

I just picked a 10 up, replaced hybrid battery and I gotta clean egr tube but with 267k on it, it seems to be going good no signs of a head gasket issue

Michael Roettgen (not verified)    December 30, 2021 - 11:52PM

I own Prius 2010, and I have over 215 K. None of problems that were mentioned happened to me. The head light I had to replace 3 times, only one bulb at the time, other than that it's an awesome car!!!

Mathew R Tofanelli (not verified)    December 31, 2021 - 12:58AM

I just sold my 2010 Prius that put up a red triangle and said hybrid problem. It had 321928 miles on it. All I ever did was change oil, brakes and headlights. A guy drove 6 hours to my place, handed me $2300 and we loaded it on his car dolly. That b as d ass car didn't owe me a dime. Good job Toyota.

I have a 2007 Prius with 48k miles, fuel it up once a year, but because I'm broke now haven't changed the oil or had it tuned up in 4-5 years, I've only replaced the 12v 2x... I've been in 2 accidents 2008 & 2013 and it's still running like new.

Based on what's happening with Gen 3, I feel I wouldn't be so fortunate as I've been with my white Gen 2 I wash every time before going out, which is about 1x every 20 days to only drive about 2 miles radius.

Toyotas are the frckn best!

This article listed two problems I have already experienced with my 2012 Prius V.
It was trouble free for the first 9 years, when I got to the 80,000 km mark. Since then the EGR valve assembly was replaced because of carbon builduy ($1,350 for new valve and labour) and last week my car lost power while driving (@ 84,000 km) and all the the dashboard warning lights lit up, but I was able to park it safely. Had to have it towed to the workshop. The Toyota dealer called me up the next day to tell me that the inverter had to be replaced and it would cost $5,500 to repair. So the author, Peter Neilson, is spot on, buyer beware!

I own a 2013 Prius..I have 150K miles on it.and have.never experienced any of this problems!

Marc Hogan (not verified)    January 10, 2022 - 7:59AM

Purchased a 2013 and 6 months later the engine needs to be replaced. Could I replaced with 4th gen battery, since getting a used gen 3 might present the same problem? If is, so which year do you recommend?

Tim (not verified)    January 10, 2022 - 11:04PM

230k miles on my 2010, only replacement parts were a pair of rear hubs, $90 and an hour to replace them. One was bad, so I just did them both. I replaced the traction battery around 215k miles, and the 12v battery after about 9 years.

DougH (not verified)    January 12, 2022 - 10:18PM

This is overblown. My 2010 has 240k miles, the only maintenance has been regular oil changes. That car doesn't owe me a dime, if I jinx myself and it blows tomorrow it still will have been a stellar vehicle.

Fran (not verified)    January 14, 2022 - 1:24PM

2010 Prius. Night mare starting at 24k miles. 3 weeks after an oil change there was barely any oil in car. Dealership and Toyota rep said they would stand behind the engine. Burned oil like crazy. Begged dealership for help. Plus the EGR system had to be replaced. I had them repair any and all warranty I could find. They finally told me to get over the promise they made. So I bought a Mazda after barely getting 94K on the Prius. I had bought 4 cars from that Toyota dealership and I will drive to the next town before buying anything from them. Yes take the advice in this article.

Tony (not verified)    January 14, 2022 - 10:53PM

That's may have happened to that person. But I have a 2002 Prius with 241K, running excellent. A 2004 with 379K, and a 2010 with 354K. 2010 over 5 yes needed brakes, a/c pump, and an inverter pump once about 5 yrs ago. Nothing else. The 2004 was similar needed water pump, muffler a couple of cells in the main battery, a blower fan.
The 2002 is very little as well. Tires small Aux battery in the trunk, front brakes, a few battery cells in the big battery pack. All cars need something. Just got to shop an find the best deals to have repairs done. Or do most yourself and send only the bigger jobs out.

There are more reasons. Thieves like taking a Prius caty converter compared to a Volt. These caty converters are not cheap at the dealers. And the theft can happen again. Oil blow back is another problem with Prius according to Scotty the mechanic and he is in love with toyota

Tony (not verified)    January 17, 2022 - 9:27PM

There was a select no. That had blow by. I believe that is in the 2010. The 1.8L. as far as catalytic converters. They are extremely expensive. But all sorts of vehicles are getting the converters stolen.
But this is some sort of ring on the recycle industry as Thieves don't need to give up there info to get money for the converters.
