My car is an 02 SE-R stock with 13k miles, synthetic conversion to amsoil and perfectly broken in with all recalls completed. I have never had a single problem. I also believe my car was made on a wednesday. If anyone has ever tried a thread like this I would like an update. What year are you drivin? How many, if any, problems have you had including engine, ecu, cat, precat and tranny? How many times have you seen mr dealer and were the problems fixed? Is your car stock or modified? Synthetic or conventional? Any idea what day of the week your car was made? Are your recalls up to date?
Who knows, maybe this will make sense of the quality control problems and if not this thread will have amusing results. Keep on rockin--Zac.
