The engine light won't go out there is a error reading of p0031 on the O2 sensor been replace 7 to 10 times and the light still stays on even resetting. I have problems year after year with my brakes over all I lost total trust in Toyota Corolla plus a lot more problems Toyota takes forever to send out the recall letters. I have 8 recalls but when you go look it up its states no recalls well this is why I lost trust Toyota doesn't care they use to be the best car ever not anymore.
