Engine Burning Oil Problems of Toyota Prius - part 1

This vehicle has been burning oil for the past 10,000 miles. Vehicle has had all services and synthetic oil changes done from day 1 at the dealership. Oil changes every 5,000 miles since day 1. At 90,000 miles the car started burning oil excessively. Complaints and diagnostics were attempted at Toyota franchise dealerships but they failed to find the issue. Finally at 100,000 miles the engine failed due to head gasket failure. This vehicle is classified as a partial zero emission vehicle and it is registered in a state that follows California air resource board regulations and is being serviced in a state that follows as well. Under the pzev regulations, Toyota warranties emission related components for 15 years or 150,000 miles. Under Toyotas warranty guide it states seals and gaskets are covered. The manual does not clarify any further leaving the coverage level vague and questionable. Upon trying to get Toyota to replace the engine, they gave us a week of no responses and finally declining the claim even when the manual states it should be covered. The oil burning issue with this motor is a big problem that Toyota has been trying to cover up. Toyota is quoting $13,000 for engine replacement. They have a service bulleting regarding the oil burning because it's a known issue, but they only honor claims under the 5 year 60,000 miles power train warranty.

We hare recently started experiencing excessive oil consumption without dash warning. Our car burned 2 quarts of oil in 150 miles with no warning. Toyota has issued an internal service bulletin (t-sb-0169-16) that covers our VIN number, but since we are beyond warranty they made no offer to help (we were not notified while the vehicle was under warranty). Essentially our car was in motion at highway speeds with little or no oil, but no warning that there was no oil. I think we got very lucky that our drive ended before the engine failed.

Vehicle has been consuming oil to the point where the vehicle needs monthly oil changes. Was told many Toyota Prius models have had an oil consumption issue and that I should file a complaint.

The engine went stalled in the middle of the highway. Lucky enough, I was able to stop the car safely without any collusion. Brought the vehicle to a mechanic and diagnosed with excessive consumption of engine oil. The engine had catastrophic damage and needed a replacement. I spoke to piercey Toyota service director ken johnson and he stated there is no active recall for the vehicle and do not believe it is the vehicle issue. I do not believe that is the case, further investigation is needed to prevent other same model drivers from a deadly engine stalling crash.

Exsesive oil consumption. Need to add oil ( 2 quarts or more) between oil changes.

Bought this car brand new in 2012 and have always performed maintenance on time. Between the last oil change and this oil change the Prius is burning oil and I am having to add at least two quarts of oil before it is back on the dipstick. I am noticing this is a problem with the 2010-2014 Prius and that Toyota has done nothing to solve it. I do not want to be on a long trip and burn through oil and lock my engine up causing harm to myself or others.

Son was driving car on city street going around 35 mph, then 20 brakes went out completely until parked. Started with a loud beep noise, lights on dash then brakes no longer worked. He had to push as hard as he could to try and at least slow car down not to hit car in front of him, pulled into bike lane to avoid crash as car would not stop. Turned car off and left in parking lot. I went to get car to drive home and then brakes were working. However scared to let him drive it in case issues happen s again. Have not taken to dealership yet. The other issue is since we purchase the car burns oil, car has around 130k miles and before 3000 miles up have less then quart of oil and no. Lwaks in drive way therefore feel it must be buring oil. Add ouk at each gass fill up to avoid no oil.

Toyota dealership refused on recall based on defected steering shaft which was bought by me and fixed by mechanic. It was critical issue and recall in other models as well. Also, Toyota does not fix defective piston rings based on excessive oil consumption -https://attachments. Priuschat. Com/attachment-files/2019/04/165269_t-sb-0169-16. Pdf. Please help me at least recover some money for the part and finally let them be responsible for burned oil in engine!.

Unknown squeaking at the back, none of the mechanics was able identify the sound on the back seat . . . Oil burning, bulbs burning so often.

Engine is starting to burn oil after 120000 miles. Appears engine has an inherent design flaw as the solution to this problem per Toyota is to replace rings and pistons at a $4500 cost to the owner. Spoke to Toyota customer care and they say they haven't heard anything yet I took my car to a Toyota dealership and the service advisor said that Toyota knows all about the problem so someone is not telling the truth. I believe that Toyota should step up and repair this defect now that they know they have it at their cost. I had a 100000 warranty on the vehicle and have always serviced it every 5000 miles. That's how I found out that I had the problem. The next problem is that the owners are going to sell their vehicles to an unsuspecting owner who will inherent this problem. Also, the value of my car will diminish as a result of this defect. Toyota just wants this problem to go away and that's not right that they don't make an accommodation to help the consumer who has trusted them over the many years. I have purchased 3 other Toyota s over the years and they all lived up to the quality that Toyota sells to the consumer. This time they have an inherent design issue that they want to sweep under the rug.

Excess oil consumption, used 2 quarts of oil before next oil change, Toyota's don't consume oil the way this car does , I've never owned a car with this problem using so much oil. The burnt oil is going to eventually build up causing more issues in the combustion chambers and smog devices .

Excessive motor oil burning at a rate of 2 quarts every 5000 miles. Dealer claims is normal wear and tear. Dealer confirms that there is no leakage.

I was aware the check engine light and alarm came on when I would make right or left hand turns. Took my vehicle in for a check. Was told there "was no oil on the dipstick" so had my oil changed on 2/21/2018 and my mileage was 72704. They did an oil consumption test at this time. When I returned at 73696 miles to have phase two of the test checked, the oil was at "full level". Now at 77,250 miles and am having to add oil again. Stopped at Toyota service on 6/01/2018 for them to check the warning light. Vehicle was low on oil again. They topped off the oil at no charge. Thank you! when asked what else could be done about this problem, I was told I could replace the engine. Not going to happen with my 2010 Prius. Not due for an oil change for quite some time. Guess I will check and add oil as needed in the interim.

Defective engine required replacement prior to 139k miles (due to cylinder malfunction and excessive oil consumption), at a cost of $3700 for a used one. This has also damaged the catalytic converter, quoted at $900. At 149k miles, the hybrid battery has failed as well, which has a quoted replacement cost of $2400. While slightly outside of warranty, the engine and hybrid battery are both core components that are expected to last significantly longer. In carb states, Toyota even warrants the hybrid battery for 150k miles. The cost of replacing them exceeds the kbb value of the car, which is unacceptable for a 10 year old vehicle with average mileage that was properly maintained. I contacted both the dealership and manufacturer, and neither will accept any ownership in the matter, or provide assistance on repair costs.

My 2009 Toyota Prius has 100,700 miles on it. When I took it in for it's last oil change I was informed that only a little over a quart of oil drained from the engine. I have religiously changed the oil every 3,000 miles. After replacing the engine oil it still looked dirty. The engine is burning oil. I understand that this is a common issue caused by a piston design flaw and does not have a cheap solution other than adding oil at each gas fill up. I am concerned that the engine may stop working while driving, particularly if traveling on a long trip at highway speeds. I do not feel safe driving this vehicle on a long trip.

Excessive oil consumption. One quart down every 1500 miles. First noticed Jan 5, 2018.

Car burns a quart of oil every 1000 miles which started at 150k. This is an ongoing problem that cant be fixed.

My 2010 Toyota Prius was impeccably maintained by desert Toyota of tucson, all service records kept. Oil was changed every 5,000 miles rather than the dealer-recommended 10,000. This was my 4th Toyota and I expected it, like my other Toyotas, to have no significant problems for years. But suddenly in 2017, when the engine turned over 107,000 miles (thus making it out of warranty), I happened to check the oil (several thousand miles before the next service was due) and found it near the bottom of the dipstick. It was fortunate that I checked it because I was able to add oil and save the engine. The car performed as before, but continued to burn about a quart of motor oil every 1000 to 1500 miles. There was no evidence of either smoke from the exhaust, or oil stains underneath the car. My service person at desert merely shrugged and said this kind of thing happened occasionally, offered no remedy or contact with the Toyota rep. I began to search the internet, finding that there have been thousands of 2010 Toyota Priuses with this problem. I have kept the car on the road but am awaiting a reimbursed remedy from Toyota, possibly through a class action suit. This oil leakage poses incalculable safety risks to the environment in pollution and unpredictable occurrences. Toyota owners do not expect a $5000 engine repair on a $25,000 car within 7 years of purchase, nor should they be responsible for a Toyota defect which conveniently occurs when the car is just out of engjine warranty.

Engine burning excessive amount of oil. Car has been regularly serviced. Last night, I noticed that the oil reservoir level was so low, the dip stick did not even register it. I had to add 2. 5 quarts of oil before it started reading the oil level again.

My car is burning excessive oil.

Excessive oil consumption.

My 2010 Prius with 167,000 has begun burning engine oil at a rate of about 1 quart per thousand miles. 9 weeks after my last oil change and the engine was down 3 quarts of oil. Mpg has gone down slightly during this time and no check engine light or low oil pressure warning lights came on.

Once my car got past 100,000 miles, the non-specific warning light started coming on and the word "problem!" would come on the screen. Manual says to ask dealer what the specific problem is. Certified Toyota dealer kept saying they don't know. Turns out after my own persistence that the problem is heavy oil consumption. Not burning; not leaking. Just high consumption. Take car for regular maintenance and it seems Toyota is aware of the issue, but keeps pressing me to get a new engine, rather than offering any intermediate solutions. Could have told me thousands of miles ago to at least keep adding oil, but they never bothered. I now know after about a year that I have to start adding a lot of oil just a few weeks after the oil is changed and filled. If I wait until regular maintenance interval, all oil will be gone. Engine would have broken down if I didn't persist in figuring out what was going on. Went through 3 regular service appointments before I realized what was happening on my own. Problem was at its worst when braking, but light came on at other times as well. I have yesterday's date here on the complaint, but this has been happening about a year.

My car has started to burn oil at an alarming rate: 2 quarts between oil changes at 5,000 miles. This does not seem normal. There does not appear to be a leak.

Excessive oil consumption of approximately 1 quart per 1,000 miles as of may 2019. Toyota agreed to do a oil consumption test in July 2017 but determined that 1 quart per 1,200 miles was within normal range. Consumption problem has gotten worse and will probably result in having the engine block replaced with a used one at a cost of approximately $5,000.

The engine is now burning oil and must be replaced. Toyota is quoting me over 3,000 in parts.

Excessive oil consumption led to engine failure and replacement cost of approximately $5000. 00 also excessive oil cost to constantly fill oil over the years. I purchased the vehicle new. And got stuck with it as I was going through divorce and not working it was unfortunately cheaper to pay for a used engine replacement through Toyota. I have saved all receipts in hopes of recuperating money in the future.

My pruis is burning oil at a faster rate than it should be.

I've had two Toyota Prius in my lifetime, a 2005 and a 2010 Toyota Prius, both have had the same issue where the engine would eat up all of my oil, I would have an oil change done and less than 2 weeks later I would have to check the oil gauge rod and find that the oil levels were below the bottom line, almost empty! the engine would be burning oil at such an alarming rate that I would repeatedly bring the vehicle to Toyota for oil changes. I'm very unsatisfied with my Toyota Priuses. My car is currently at 166,384 miles and the engine cylinder has now given way and also the hybrid battery. I've gone only to Toyota dealerships to have pristine consecutive service and no third party repair facilities have provided service. I am located in souther California in san diego. I have spoken to many other Toyota Prius owners and if you do a google search online as of (04/10/17) "Toyota Prius engine oil consumption" you'll find many forums with "excessive consumption" from many other users. Once you reach past the 140,000 mile mark, your car is pretty much done. Consider buying a new one. Toyota Priuses and their engineers have to come up with a way to satisfy current and future Prius owners as many of us will find that there will be many problems and issues down the road.

2010 Toyota Prius failed an oil engine consumption test at 98,000 miles. It burned 3 quarts in 1,100 miles. Toyota has service bulletin issued in November 2016 to cover this car but inherently, it isn't covered. I have service records that this was happening in June 2015 at 82000 miles, before I bought the car in sept 2016. Toyota will only cover half of $3000 cost of repair. Issue appears to be widespread, across many models from what I've read online and experienced in the dealership. Toyota's failure to address this situation when it has been happening for years is highly alarming, considering it affects a major part of the engine.

On picking up my Prius after routine maintenance, I was told that it was 3 quarts low in engine oil. I was stunned as I had had no warning of low oil pressure or loss of performance. The dealer is conducting an "oil consumption test" to measure how much oil will be consumed in 1200 miles. The estimated repair cost was $2000, but my husband who is very knowledgeable about engines doesn't believe the suggested repair will fix the problem. I have only recently become aware that this is a prevalent problem with late model Toyotas, not just Prius. The customer service agent and the service tech we spoke with were cagey when asked how frequently they have seen this problem. I believe Toyota is very aware of the issue, but are willfully not addressing a remedy.

Oil consumption terrible. Need to add 1 qt of oil every 1,100 miles. Engine is burning a ton of oil.

Excessive oil consumption after having my oil changed at the dealership at 100k miles, I left on a cross-country trip. During the trip, the low oil pressure signal flashed on my dashboard. Upon pulling over and checking the oil, I found there was no oil in the engine at all. I added 4 quarts checking the level in increments with the dipstick, and continued. I had to add an additional quart of oil to the engine over the following week, until returning home. Upon returning, the dealership refused to accept any responsibility for the issue and informed me that I needed new pistons and rings. They did not inform me that this is a recurring issue with my generation of Prius and were quite firm that it was not their problem. There is not reason that a Toyota with 100,000 mile on it should randomly start burning excessive amounts of oil within a few thousand miles of an oil and filter change. All of the maintenance is performed at the dealership at the specified intervals, and I would expect that Toyota would stand behind a Toyota that is maintained per Toyota specifications.

1st - excessive oil consumption. . . Bought the vehicle new in 2013, never had to refill engine oil in between oil changes of every 10,000 miles (synthetic oil 0w 20). At appx a little over 100,000 miles, check engine light came on and when I checked the dipstick, no oil is registering. Went to a gas station and purchased 1 qt of mobil 1 0w20 and after pouring it in, still not showing any oil in the dipstick. Purchased another quart and finally showed closed to half on the dipstick. I am now averaging appx 1 qt of add on oil every 1200 miles or so, again using 0w20. 2nd - poor mpg. . . From brand new till appx 70,000 miles or so, was averaging 40 - 42 mpg. Took the car in 2015 for a software recall and immediately, mpg went to 35 - 36 mpg. Dealer claims nothing to do with the recall and blames it on my newly purchased all season pirelli tires. Was told mpg will improve once tires has maybe 1000 miles or so on it. Its been appx 60,000 miles now and mpg has not improved at all. Always on eco mode and gently drives the car just like when it was brand new in pretty much same places / condition - southern California. It sounds like rpm is too high. . . . Its always on drive and not on lower gear (b) and no heavy load or trailer besides usual passenger of appx 2 to 3 (kids + adult).
