Four problems related to engine oil leaking have been reported for the 2011 Toyota Prius. The most recently reported issues are listed below.
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.
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.
"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 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.
