The problem is and has been excess oil usuage. It uses a quart about every 400 hundred miles. I bought the car used at a local Honda dealer may, 2010. It had 102,000 miles on it. It now has 117,000. It's been using oil every since I've had it. I took it back to the dealer and they couldn't find any thing wrong. They said the engine was clean and there were no oil leaks anywhere. I've searched the internet and there are alot of complaints posted about this car. The problem is the engine put in the car in 2002. A 1. 6l was replaced with a new 1. 8l engine and evidently the 1. 8l didn't seat properly causing oil usuage. My son drove this car while he was at college. The problem is, with this kind of oil usage, you can run the car out of oil. We tried to keep up with it, but if you run it high speeds it will use more oil. If the car runs out of oil on an interstate and the engine locks up, well you could have a serious safety problem. I keep the car at home now because of the safety concerns. We drive it locally only.
I have a 2002 Toyota Corolla that uses an excessive amount of oil it is not leaking it out it is burning it. After reading numerous complaints of virtually the same problems from other Toyota Corolla consumers I believe this seems to be a common problem in this year make and model. I even had to replace my catalytic converter due to the problem. My local Toyota dealership told me to call the national Toyota customer experience line and they told me that this was not a recognized problem. From everything that I have been told from car repair places and the internet I must "your looking at a complete overhaul. . . You want to replace the piston rings and valve stems. . . But every gasket you touch or go near should be replaced along the way. Also add in incidentals for items that break or things that are discovered along the way. . . " Toyota will not admit that this is a manufacturing problem; however, lots of people are having issues with it including myself. I have not done an overhaul of the engine because I am looking for Toyota to take responsibility for their poor work. I did replace the catalytic converter in July of 2009. Right now I am going through all my in less than 3,000 miles. I have to put oil in before my regular oil changes. Now I am just waiting for the next major replacement due to this problem. Many others are putting quarts of oil in every 1,000 miles or less. I can't wait until I get to this point to have this resolved.
