Purchased a Toyota Corolla with extended warranty. Around 91,000 miles the red oil light comes on. Drove the balance of the way to work they took it to the dealer. The dealer tell me the car is not under warranty because the oil pick up is filled with oil sludge. This is the first car were I change the oil every 6000 miles like clock work. The dealer would not honor any thing which sucks. Darn I did all the maintenance required and I'm still screwed. I used Pennzoil oil for all oil changes and learned later this may have been my problem

This car was only 1-1/2 yrs old, and we did all the routine maintenance. Our car was just past the warranty, but we paid a couple of thousand dollars for the extended warranty. Yet, the dealership refused to fix it!!! They said our engine had sludge, which is a problem we have since found to be a common problem with Toyota car. Apparently, if you type Toyota and sludge into a search, there are tons of evidence of this being a known problem. Yet, they will not fix the car. So I had it towed to their shop and told them to shove it up their back sides!!
