Ever since purchasing my 2011 Prius, it has always used a ton of oil. I recently had the head gasket replaced, new coils, plugs, and injectors, EGR cooler cleaned and timing gasket replaced all due to the amount of oil it was consuming. Well, that was less than 1k miles ago and today my motor blew, threw a rod right through the block of the motor.

These years are known for the lack of quality materials used in the rods apparently, they bend or warp easy. Who would have known.. I am just sad that Toyota knew all of these issues but refused to stand up and do anything to fix them. I really want to buy another Prius because they are great little cars but I am having a hard time getting behind a company that it unwilling to fix what they know is broken.

Vehicle began using excessive oil several months ago. Oil usage seemed to slow down. Car was in for recall and mechanic discovered an "oil seep" from the timing cover gasket. Estimated repair cost was $2400!!!! Dealership said this was common in those engines. IF it was common why is it not being repaired by Toyota? We will never purchase another hybrid Toyota after all the hybrid issues. And by the way, because our car (1 of 4) does not consume the average amount of fuel as other cars the government has placed an added tax on the hybrid so we will pay our FAIR SHARE OF THE STATE GASOLINE TAX!$%%$#. Never again will we try to save energy.

I have a 2011 Toyota Prius that burns excessive amounts of oil. It started slow, as was the case with the 3 Prius I had prior to this one. Now at 180,000 miles, it is burning roughly 1 quart per 1000 miles. Again, as with all 3 vehicles before this one, Toyota claims it is "normal consumption" and refuses to acknowledge the problem. As with my last 3 Prius, I feel this one will seize on the side of the road as the others have in the past. This is profoundly frustrating, especially since Toyota touts such great reliability. 4 Prius with the same issue and a 4Runner that literally rusted off the frame.

As with the other 3 times this has occurred, Toyota will suggest either trading the car in or replacing the engine at the cost of roughly $5000. Seems like you should do the right thing and fix all the issues your loyal customers have been experiencing!

2011Toyota Prius with excessive oil leak issues. I've been told there is no fix for it outside of an engine replacement. I have to add oil every 1000 miles and bring my car in for an oil change every 2000 miles which is inconvenient, forces me to use my vacation time hours at work, and is completely contrary to the owners manual which states oil changes are needed every 10,000 miles or 12 months. I have to check and/or change my oil 10x the required scheduled oil maintenance schedule. This should not be the case. Toyota needs to fix this issue.

I had purchased a used 2011 Toyota Prius back in 2013. When purchased at the dealership, there was no mention of any of the recalls that involves the cars or any problems I might run into. When getting oil change done whether at the dealership or anywhere else, there was no mention of the car using too much oil. Until recently when my cousin recommended I take my car to his personal mechanic, who advised that I should check my oil regularly as the car seems to be burning oil at such a fast pace. anyway, 2 weeks after I had my oil changed with him, I checked the oil and indeed there was nothing. It was a good thing he advised me to keep extra oil in car so that I can add oil when its low or empty. I will be calling the dealership I had bought the car from and inform them of the problem and see what they have to say. I am not expecting any help from them though....

I am at 130k miles and burn about 1 quart every 2,000 miles. Other than issue a TSB, I am pretty bummed to see how long and for how many people this has been a problem and Toyota is not doing anything about it. Evidently they figure if you got 100k miles out of their car, that's good enough. I read that some auto dealer in Walpole, MA claimed that this wouldn't be a problem if people changed their oil every 5k miles instead of going longer between oil changes. Hog wash!! I have changed the oil in my car every 3,000-5,000 miles for the life of this car and still have this problem.

My 2011 Toyota Prius started briefly beeping master warning when turning corners or stopping hard but did not tell me what was wrong. It was running fine. Finally it said oil pressure low and I checked the dipstick which revealed no oil in car! Had it towed to dealer where I have always had maintenance work/oil changes completed. They ran diagnostic and say the pistons are shot and whole engine must be replaced for $4,800!

I am beyond frustrated! Bought this car, my first Toyota, thinking it would be a great dependable car. Was told I had to change oil every 10,000 miles. Did not expect such a major problem after 6 years and 95,00 miles. Of course my extended warranty was no good. (72 month/75,000 miles.) Looking online I see other who have had problems with excessive oil consumption. Not sure if there is any other recourse other than to pay for new engine. Will never buy another Toyota and will advise others not to either.

I always have the dealer change my oil (100% synthetic.) Never had an issue, and never checked level before.

Since the last oil change, mileage decreased significantly... and after a (hot!) round trip from CO to MO and back, suddenly I was getting oil warning light when cornering.

I checked oil level: 2 1/2 quarts low! And now it appears to be burning oil. The dealer said in his experience, LOTS of 2011 Prii have this problem. He said there had been a warranty extension on this but it has expired, so he recommended using an additive for high-mileage vehicles.

I looked online: I see an extension for other Toyotas but not the Prius. Apparently there's an issue with piston ring/lubrication design.

I am seriously wondering how to forcefully yet nicely ask Toyota to consider including the Prius in this obvious design flaw issue.

My 2011 prius has started to burn a quart or so every 1000 miles. My dealer recommends oil changes every 10k. So i put in 10 quarts of oil every time they 'change' 5 quarts? How is that right? And what's the longevity of the engine when this much oil is blowing by the rings? Used to be ecstatic at how efficient and maintenance free this little car, my first import, was. Now i'm genuinely concerned and I wonder if i should trade it in before it catastrophically fails. Somebody smarter than me needs to start a class action and force toyota to agree to cover the costs of repair and/or replacement.

Driving less than 1200 miles and need to add expensive oil. Most miles are highway, not stop n go. Vehicle now has 125,000 miles and we are concerned it will not last much longer, which is totally unacceptable for a $23,000 vehicle. That is more than .18 per mile just to have the car. Add gas & maintenance, Toyotas are extremely expensive to drive! Dealer says $3500 to $5000 to replace engine. I spoke with Toyota Customer Care. They don't consider us "Brand Loyal" even though we have purchased 3 Toyotas in the last 20, so won't do anything for us. I explained we live in the real world and don't buy a new car every other year. Even though it is their defective car that has the issue, we end up paying for their poor engineering.

Toyota claims there are not enough issues with the 2011 cars, but they only tabulate the cars that people contact them directly. Even though they know from their dealers exactly how many have been brought in for the "excessive oil" test, they will not log that vehicle unless the owner calls them to complain. SO if you have a problem - PLEASE call the Toyota Customer Care Center. Even though they will do absolutely nothing for you, it may help accumulate the numbers on their "Acknowledged Record" for them to issue a recall/fix.

The guy with all the money wins again :(

Toyota has acknowledged that certain models (Camry, Rav4, Corolla) have excessive oil consumption issues, but not the Prius. I discovered the problem last month (April 2017) when I took my car in for the 95,000 mid term service. It wasn't supposed to be an oil change. Found that I was just over two quarts low. I just brought it in and it has been about 1200 miles since the last check and I am two quarts low. That means I'm going through about a quart every 600 miles. Dangerous situation. Very disappointing. I own three Toyotas and I'm hoping they come through and fix this problem or I'll be taking my business elsewhere next time.
