Prius Hybrid 1.8L

  • Automatic transmission
  • 100,000 miles

A D V E R T I S E M E N T S

I BOUGHT MY 2010 TOYOTA PRIUS 4 USED IN 2014 WITH 56000 MILES ON IT. I HAD THE OIL CHANGED BY A LOCAL TOYOTA DEALERSHIP EVERY 5000 MILES EVEN THOUGH THEY SAID IT COULD GO TO 10000 BEFORE CHANGING.

AT ABOUT 100000 MILES THE DEALERSHIP TELLS ME AFTER CHANGING MY OIL THAT IT WAS LOW SO I STARTED CHECKING IT EVERY 500 MILES.

FOUND OUT IT WAS USING A QUART EVERY 1000 MILES SO I COMPLAINED TO THE DEALERSHIP ABOUT IT AND THEY SAID OH THAT IS NORMAL FOR THESE CARS ( THE PRIUS )

I DID SOME ONLINE RESEARCH AND FOUND THAT THERE ARE MANY MANY OTHER PRIUS OWNERS WITH THE SAME PROBLEM THAT ARE BEING TOLD THE SAME THING. THIS IS NOT NORMAL!!!

BY WHAT I HAVE READ TOYOTA INSTALLED SOME BAD PISTON RINGS ON SOME MODELS WITH THE 1.8L ENGINES AND PROBABLY OTHERS BECAUSE CERTAIN CAMRYS ARE HAVING THE SAME PROBLEM.

Prius 2zr-Fxe 1.8L I4

  • Automatic transmission
  • 146,000 miles

I bought the car used at 2013. I do a lot of the maintenance myself and I follow the manual to the dot. I am technical and the maintenance isn't really a big issue for me. Last night, about 6,000 miles after my last oil change (0W-20 Full Synth), I noticed the car threw out a "Low Engine Oil Pressure" warning. This only happened when I brake. I checked the oil dip stick, and it read nothing! Zip! I had to add 2.5 quarts of oil to get it to read again. I am afraid that the seals are leaking at 146,000 miles.

I thought that this would happen to me, but Toyota, your 2ZR-FXE needs fixing!

Prius II 1.8L

  • Automatic transmission
  • 109,000 miles

I bought a certified used 2010 Prius from a Toyota dealer in April, 2013. The car has been doing well until last few weeks. When I turn a sharp corner, a short beep short and the yellow warning light on my dashboard will flash. It went off so fast and I could read the words. It keeps on happen so after a couple weeks, I decided to go to pay a visit to my dealer. Without even opening the hook, the service adviser told me that my engine is burning oil. He needs to add 3.8 quart of engine oil, despite the fact that it was only 800 miles after my last service at the same dealer.

I asked for a quote to repair it. He quoted $4,950 because they need to rebuild the engine. I asked him about the trade in value and he said it is $0 because of the engine problem. Obviously there is no way I am going to spend so much money on a 7 years old car.

This is my third Toyota and never have this problem. I now realized Toyota car is not as reliable as I thought so I probably will go buy a new Honda in the next few weeks.

Prius 4

  • Automatic transmission
  • 60,000 miles

I'm not an auto geek or a computer geek so this has gone on for several years till it "clicked" that I have a problem with my Prius. I thought only 1964 Chevy's burned oil. It never dawned on me that my relatively new Toyota might be doing this. But, for a long time the "Low Engine Oil" message started coming on when I turned corners. I would get the oil changed (always on time and at the dealership) and it would go away. Then, in the last 10,000 miles or so, I checked the oil, found it low, put in one quart, then another, then another in order to get it to register. I was amazed. It's not leaking. It has to be going somewhere else. Some place it's not supposed to be going. My next step is to talk to the dealership or yell at them.

Engine failed consumption test from the dealer. Estimate to fix is $3800. The car is using a quart of oil every 2500 miles at the moment. The dealer said it is a known issue and referred me to the Toyota Customer Experience line. They said there is nothing they can do. The car has had all service and I have records. I even bought the extra warranty. (Battery is still under warranty. How can Toyota deny this is a known issue?

I had the dealer look at the engine and did the 1,200 mile test to see how much oil is being used and they did say it was burning more oil than usual. They have a recall on some engines but not the prius which is the same problem and similar engine. Called toyota and they would not cover the repair. If enough people complain then this should become a recall or again Toyota could care less.

I purchased a used 2010 Prius from dealer. According to service records a recent oil change was done at purchase in April 2017. Sticker on windshield with the usual 3000 mile interval date. Haven't thought about it until I got the oil maintenance required light. I checked dip stick barely above bottom dot which means very low oil. no other low oil or similar lights like I would get in an American car. I will add a quart but plan to get an oil change. I am shocked to learn of the many complaints of these cars consuming lots of oil at a certain age/mileage and believe mine is another one in the bunch. I never had a car or truck go through oil like this.

My Prius is gradually consuming more and more oil. Not leaking a drop so I know it is being consumed by the engine. About 1qt every 1000 miles and seems to be getting worse!! I see Toyota had TSB for the Camry's with a similar issue, but don't see one for the Prius yet?????

I just had an oil change two months ago -- one month left. Driving on the Interstate today and the low engine oil light came on with smoke and the car won't run. Mechanic is sending me a number of codes to send to the Toyota dealership. Hybrid battery, camshaft, timing, etc. Some major problems that will be beyond repair!

Prius

  • CVT transmission
  • 89,759 miles

Like so many other Prius owners here, I was surprised by the sudden warning alarm on my 2010 Prius. It took me a couple of days to figure out where to look on the MFD in order to read the warning message -- that flashed for only about a second, then was gone.

Ultimately, I saw the "Low engine oil pressure" message. I checked the dip stick and... nothing. A trip to the local auto parts store with three quarts of 0-20 synthetic oil should do the trick, I thought. WRONG! After adding three quarts of oil, was still a half a quart short. Another trip to the auto parts store ensued. Finally topped it off, total of 3-1/2 quarts short.

I was incredulous. How could my Prius, which historically burned hardly any oil between oil changes -- how could this car suddenly start consuming oil so quickly? Yesterday, I emailed my findings to the dealer (Capistrano Toyota) who has done all the service on this car for the past seven years. Haven't heard back yet. Not sure if I ever will -- especially after discovering this website and all the other Prius owners who have had the same problem.

Plan is to carefully monitor the car's oil levels for the indefinite future -- like I would with an old Chevy Biscayne from 1961.

This is the second major engine problem I have had with Toyotas. My first problem was in 1998. My 1993 Toyota 4-Runner V6 head gaskets failed. Luckily, Toyota fixed it for free despite that the car had over 90,000 miles on it. I sold the car immediately afterwards because they told me that if the gaskets failed again, I would be on the hook for the repairs (about $4000 back then).

But this episode has really got me reevaluating the whole idea of buying new cars – which I have been doing for the last 30 years. It seems that when problems like this pop up, the owner is left with a fairly new car – just paid off – and faced with repair bills that are about a third of the cost of the car. It happened to my 1999 Honda Odyssey van shortly after paying it off. It is on its second transmission which, by the way, now has had loud bearing noise for the last couple of years.

All of these new cars were religiously taken to the dealer for regular maintenance. But despite meticulous maintenance, these cars have experienced major and expensive failures. As others have pointed out here, what is the point of conscientious maintenance if the car ends of failing anyways?

There is a tendency to want to protect the investment and shell out the money and fix the car. But the whole idea of buying a new car is that the car will provide fairly reliable transportation for about 10 years. If a new car needs substantial repairs after only seven years, then what is the point of buying a new car? I mean, this isn’t 1960. Back then everybody understood that cars lasted maybe 90,000 miles. After that, they needed a new or rebuilt engine. I worry that despite the decades long trend in improved automotive quality, perhaps there hasn’t really been that much progress in improving the durability of drive trains after all.

So, instead of buying a new car, possibly money would be better spent buying a used car that has a reputation that it can be repaired cheaply. For example, instead of paying $25000 for a new Prius and then an additional $8000 for repairs seven years later, spend $8000 for a used car in which major repairs are somewhat cheaper. Then throw the car away after seven years. In this scenario, the effort must be done in researching repair costs. And there is additional effort in doing some initial restoration.

Then, if you need a nice reliable car for trips, rent one.

End of rant.

For now, not purchasing another Toyota unless it’s a used one that can be repaired more easily and cheaply.

Prius 1.8L

  • Automatic transmission
  • 112,000 miles

Like so many other 2010 Prius owners, around the 110,000 mile mark my car started consuming a lot more oil then it previously had. Currently (130,000 miles) I have to add approximately 4 quarts of oil in between oil changes and my catalytic converter is now 100% clogged because of the oil consumption problem. I have researched for many hours to see if there is a resolution to this problem other than me paying for another engine to be put into my 7 year old vehicle. I am so frustrated that Toyota is not owning up to this issue. In my hours of searching I did come across a Technical Service Bulletin that Toyota sent out to it's repair centers that addresses this exact issue. So, they are aware there is a problem and they have laid out the steps for the repair centers to diagnose and repair it. The problem is, this TSB dated November 2016 states that this issue is covered under warranty only for 60,000 miles or 60 Months, whichever occurs first. For a 2010 Prius this warranty has obviously already expired. Toyota needs to step up and extend the warranty on this issue or they are going to lose a lot of customers. This Prius is my 3rd Toyota. I have been loyal to Toyota and had planned on never purchasing anything but Toyota because I thought it was a good brand. I will remain loyal if they fix this issue soon but if they do not, I will never purchase another Toyota again.

Major oil consumption started at 105k. I have to add oil at every fill up. I went to thicker oil which helped a little. Gas mileage has also dropped. This is a very common issue and an obvious design flaw that Toyota chooses to ignore.

Prius

  • Automatic transmission
  • 99,000 miles

I have been going back and forth with Toyota for the last year regarding excessive oil consumption on my 2010 Prius. I initially reported the problem while my vehicle was under its 100,000 mile certification warranty coverage. They ran an oil consumption test and told me that they found that the car did not consume extra oil. (Paperwork showed it was filled with 5 quarts, the car does not require 5 quarts, therefore I am assuming it was overfilled in order to pass the test).

I then stated to the dealership that I disagreed with the findings due to the fact that I was constantly having to add quarts of oil between oil changes. They told me to call the corporate customer service number and open a case which I did and if the problem continued it and they found out what was causing it, the repairs would be covered under the certification warranty coverage because I had reported it before the coverage had ran out.

After more than one attempt, I could not get anyone from the corporate customer service number to call me back so I gave up and continued to notify the dealer every time the vehicle was in for routine service. I repeatedly told the dealership that the car was still using excessive oil and not throwing any type of oil light until there was nothing left on the dipstick and even at that, the only indication we ever receive from the vehicle is a 2 second flash on the dashboard that says low oil pressure when take a sharp turn or quick stop, other than they there is no indication the vehicle it out of oil.

They continued to tell me that they didn’t see anything wrong and the mechanics never reported that the oil was low during oil changes. Fast forward until around March or April of this year when I had the dealer replace a rear bearing and complete the usual oil change during a visit… within a week or so later there was an issue with my intake manifold. They then replaced the manifold and within the next few days I was completely out of oil. (They stated it was down over 3.5 quarts) I immediately brought the car right back to them, they said there was no way since they had literally just done the oil change.

They finally ran another oil consumption test and found it to definitely fail the test. They stated that they would send the findings over the warranty department asking that the “short block” be replaced under the warranty coverage (due to faulty pistons and such). For almost the next 2 months I continually went back and forth with them they kept saying they were waiting for an answer and had not heard back from the warranty department. So after about 6 weeks I was finally told by them that the warranty department cannot do anything because they (the dealership) never opened an initial call with them when the car was under the certification coverage to report the excessive oil consumption problem.

My service adviser at the dealership then told me to contact Toyota's corporate customer service number again which I did. They apologized for the year long run around I had been given from the dealership. They told me they would escalate the issue to the customer relations manager at the dealership, since I was not getting anywhere with the service department, they had asked for them to make the repair under the warranty cover or at the dealerships cost. The dealership then responded that they were not willing to assist in any way with the repair. The customer service manager proceeded to tell me that there was nothing he could do since the warranty call was never opened (by the dealership) when I initially reported the problem.

He also continued to tell me that he has owned a hybrid and they use lots of oil, its normal. That I should just keep adding oil on my own. I asked for a quote to do the repair and he told me that he did not have one but I would be looking at $2000 for them to even start looking at the engine to try and find the problem. He also stated that there was no records of me reporting to problem so I was pretty much stuck with it, even though the corporate number could see all of my service records which indicated that I have reported the problem since May of last year. I then called back the corporate customer service number since I was initially told they could escalate it again if the response I received was unacceptable.

When I did call back, the representative I had been working with was unavailable, so I left a message for her with the case number and everything. She returned my call 4 days later and left a message so I called back and said I was returning her call, I was told she was unavailable and that she had left a note in the record that she did not know why I was calling. That rep then proceeded to tell me that he didn’t understand why the dealership had told me to call them in the first place there is nothing they can do. He stated he could see on the records that the dealership responded saying they admit that there is a problem with excessive oil consumption but they will not be providing any type of help because the problem is no longer under coverage.

He also stated that they are just the manufacturer they cannot control what their dealerships do, they cannot make them do anything if they choose not to. I asked to speak to his manager so I could find out what my other options were and he refused to give me to anyone. He said my problems are with the dealership there is nothing they can do to help me.

After all this running in circles and wasted hours of time I am now stuck with a vehicle that clearly has an excessive oil consumption problem with absolutely no help at the dealership or from the manufacturer.

Just like the others on this site, my 2010 Prius is burning a quart of oil every 750 miles, sometime more which started around the 110k mark. I bought the Prius to reduce my carbon footprint which seems quite the paradox at the present. How can we get help; this is ABSURD!

Dec 222016

Prius

  • Automatic transmission
  • 108,000 miles

Car purchased new and serviced at Toyota dealership every 10,000 miles using 0-20W synthetic oil. At around 106,000 miles I noticed the display flashing something but could not, at that time, read what the warning was. It seemed to happen going around curves, turning etc. Finally, at maybe 107,000 miles, the warning stayed on long enough to see the low oil warning.

Took the car in at 108,000 (no oil on dipstick at that point) and the service department checked for leaks and found none. I was lightly admonished by service for driving without oil. Fair enough, I thought at the time. I was slightly chagrined as I have always religiously had my oil changed (or changed it myself) on all my cars at the recommended intervals with no signs of a problem. The Toyota service department recommended that I monitor oil usage. I did, and to my surprise 2,500 hundred miles later, I had to add a full quart. Then 1950 miles later, another quart. Yesterday, another quart at 1048 miles.

Very disappointed as the car has been without problems until now. Have not discussed this with the dealership, but am not encouraged by the tenor of comments posted here regarding Toyota stepping up and accepting responsibility. I see no need, at this point, to pay to have an oil consumption test done by the dealership as the car is obviously using an excessive amount of oil.
