Two problems related to gas recirculation valve (egr valve) have been reported for the 1999 Toyota Camry. The most recently reported issues are listed below.
Oil light came on, took to station added oil, had oil changed w/I 2 days told pcv valve bad, had changed, car smoked, took to dealer told oil in valves could have been antifreeze in oil or when told oil was changed it was not, maunfacture says improper maintance will only cover $1000 of approx. $4000 repair. Oil changed at least every 7500 as recom. In manual. Should be fully covered by warranty.
This car is a lemon. I have had five integrated relay's replaced and now it is out again. The headlight or the dash lights will work, but not both at the same time. Toyota said it was because I had a non-factory alarm installed. They replaced the alarm with a Toyota alarm and replaced the relay and it burned out the following day. They can't find the problem. The air conditioner has had a musty smell since the car was new. They spray the vents with "frigi fresh" and it's fine for a few days and the smell returns. They told me to spray simple green in the air intake once a week. That's a pretty poor remedy. The transmission will not hold on any incline. Sometimes the car will pull into the garage by it self and other times it will roll into the street. It depends on it's mood. The car lack power. Some days the car is peppy but most days it's a old mule. I went through arbitration and Toyota just keeps replacing parts instead of replacing the car. It's sits in the garage now because is not dependable. I think there needs to be an in-depth investigation and recall of the 1999 Camry.
