Still investigating the validity of the knee air bag as standard features for 2004 2.5X.
Also, the check engine light mysteriously went away. I will drive the car for a few more days before I take it in for service. I don't want to be visiting the dealership for every little problems. I guess I have to realize, and accept that Jaguar doesn't have the same reliability of Acura, which is what I drove for many years.
