Engine developed an oil leak around 120,000 miles. Dealer ran an oil leak test ($700)and performed something else for $300 dollars. Nothing work. Dealer says the fix is to buy a new short block for $6,700. I will not. I'm adding oil myself to car about once every 10 days.

Dealer mechanics at Toyota berkeley, Toyota vallejo and city in daly city all have stated that the crack in my oil tank is a �well known� manufacturer defect. The mechanics state when building that part, a machine clamped the 2 parts together. But the machine doesn't wipe it down beforehand and any oil will keep the 2 pieces separated, which eventually form a crack. When the oil is left unchanged for a period of time the crack gets bigger, the oil leaks and eventually doesn't work. I was told if I keep up with my regular oil changes, it should work. But I get anxiety now every time that maintenance light goes on and I feel like I have to change the oil immediately or else.

Vehicle after awhile starts to consume oil. It's runs out of oil very quickly. There is no oil leak.

Prius started consuming oil around the 105,000 mile mark. Two months ago, I took it to the dealer and they had me come back after 1100 miles after my oil change. They said it was consuming oil because the piston rings were leaking. The lady tried to sell me a used engine for 3,000 or 5,000 dollars. I told her that is why I bought Toyota because I didn't want to spend money after 100,000 miles. I have looked online and this practically happening to all the 2010-2011 prii. My buddy owns and camry and just had his block/piston rings changed for the same problem. This morning, I am a 100 miles from the need of an oil change, and when apply the breaks I get a yellow light coming on saying "not enough oil pressure". I google this and people are saying it is because my oil is low again. I think Toyota is trying to avoid having to recall this.

My car had performed perfectly for the first 100k miles. By 112k miles the oil was very low, no oil on the dip stick when I went in to have the oil change. Yet there was no low oil light or engine light to warn me. This was a complete surprise to me since that had never happened before and the usage had been at a normal rate up until then. I began looking for leaks, etc with no evidence of that. The next service it was again extremely low. I now know that I must add about a quart every 1000 miles to keep up with its demand. The dealer and other mechanics all tell me the only solution is a new engine. Some suggest a used or rebuilt one though they are still many thousands of dollars. This problem, they say, will only get worse, clogging the spark plugs and potentially having an incident of engine stalling or shutting totally down while driving. This is a safety issue that Toyota should be fixing. I paid $1500 for an extended warranty for the first 100k miles with no problems, and now, it seems, I am stuck with a true lemon! this car should be listed with the others that Toyota has acknowledged have engine defects because it has the same problem. I will never by another Toyota unless they warranty this issue. The word is getting out. They do not take care of their defect problems. So much for the very undeserved reputation of many Toyota models!.

Every time I get an oil change I make sure that the right amount of oil gets put in the engine. I usually get an oil change every 3000 miles regardless of what the oil manufacturers recommend which is usually 5-7 thousands miles. For the past year I started noticing (usually by the oil service tech) that more and more I'm running low on oil. It started out with a half to one quart of oil missing between oil changes to now 2-3 quarts missing between oil changes. I understand that my 2004 Prius is approaching 200k miles but I have always taken great care of my car and now all of a sudden I'm having to top off the oil every week. There's absolutely no oil leak and I don't see any white or black smoke from the exhaust. I'm pretty disappointed because I have just recently had to replace my hybrid battery ($2800) and if the engine is going to need to be replaced as well than I mind as well just junk it as it won't be worth it at that point.

Used 2 qts of oil for every 1500 miles. There are no leaking of oil found under engine.

This is the first car we ever owned that ate oil. We are meticulous about servicing the car as recommended every 5000 miles. At the service for 100,000 miles which we did at 99,400 miles, there was no oil on the dipstick. At 103,000 miles the alarms went off 3 times to indicate there was no oil. We put in 2 quarts and took it to the shop for a diagnostic. Googling showed many other people with the same problem - no oil leak anywhere, but no oil in the car either. Toyota apparently knows of the problem and has informed service providers but will not acknowledge this problem to the car owners. We now carry oil in the car and check every time we put in gas to make sure we also have oil. The service shop suggests a $3500+ rebuild of the engine. We can afford to check oil and add it as necessary instead of rebuilding an engine that will end up with the same issue. It is unacceptable that the expectation is to add oil between every 5000 miles, as recommended by manufacturer, instead of the assurance that the car will be able to make it to each 5000 mile interval without adding additional oil. We also cannot afford to have the engine seize up in what is marketed as a very dependable car from a very dependable manufacturer. Apparently Toyota doesn't make cars that exceed a lifetime of 100,000 miles and are also a very undependable manufacturer of cars.

"takata recall" this is our first Toyota purchase and we are extremely let down with the fact that it is losing an excessive amount of oil. This is a safety issue. In the event that the engine may cease if it runs out of oil. We previously have only had american vehicles, and were told that Toyota is a much better product. . Well as of this past April, we had this brief light go on. It doesn't stay on very long and only appears when you turn a curve. Then the "oil maintenance due" light appeared. That's odd, because I just had my oil change done 2 months ago! I went to a local oil service station immediately and found out I was down to only one quart of oil in my engine. I've never had this happen before! they looked for a leak and didn't find one. They topped off the oil and I was free to go. Well, the same scenario happened again in July, only 3 months after the last top off. I made an appointment with the dealer to have him look it over. They said it needed a system engine cleaning, there were no leaks, they gave it an oil change, and the spark plugs looked fine. . $300 for this to be done. Then they told me to bring it back in 1900 miles. . . Well this seemed to work. . . Until. . . Now. . In October/November (2-3 mos later) the same issue happened, and now they are telling me I need a new engine that will cost anywhere from $3000 to $5800. I have only had this car going on 5 years. I have never had to replace an engine on any car before. . Where is the Toyota quality we were told Toyota stands behind???.

This car leaks oil . I have to put a quart in each time before oil change is due.

This car consumes oil. . . It dose not leak the oil and the dealer says that one quart in 1200 miles is normal. . . This oil is polluting the atmosphere and is expensive. I fi was told that it would consume this much oil at 100k, I would not have purchased the car.

Engine oil disappears constantly. There is no apparent leakage of engine oil. Have taken to Toyota dealers during servicing many times since than and mentioned the problem. They couldn't figure out why it is happening. In order to keep engine oil in recommended level I have been pouring recommended grade engine oil (5w30) every other week.

Engine stalling occurring randomly while cruising at highway speed between approx. 54 to 64 mph causing vehicle to slow down on the freeway. This problem is potentially hazardous because engine stalls at freeway speed which could result in rear end crash from on-coming vehicles traveling behind at freeway speeds --- furthermore the vehicle must be stopped at the freeway edge to be restarted before problem is corrected. Restarting vehicle immediately corrects problem. However, this problem should be made a mandatory recall item. [prius scanner shows dtc code p1120 for accelerator pedal assembly problem and there is a manufacturer TSB concerning this problem (TSB eg018-02)]. This vehicle has had the crankshaft sensor replaced pursuant to the recent recall notice and the crankshaft sensor had been leaking oil prior to replacement. Also drivers rear axle hub bearing failed prematurely and was recently replaced.
