Update:
The antifreeze leak on the car was originating from the front right engine gasket. Fortunately, the repair was accepted as a warranty repair since my
2000 Legacy GT Sedan had only 53,000 miles on it. At first the guys at Don Beyer (Alexandria, VA) told me that they couldn't find the leak, I was outraged and told them that I was going to conference them in with the mechanic that found the leak and issued the mechanic diagnostic report.Then they told me: "Sorry Mr. Rosario, we were looking at the wrong car" so they inspected the car and agreed that the car had a leak and serviced it as a warranty repair.
The car is driving fine, but the Oxygen Sensor triggered the infamous "check engine light" 1 days after I took it from the dealership. The dealership replace the oxygen sensor--FOR THE RECORD--this is the second time that they replaced the oxygen sensor, we changed it 2 years ago because of a recall notice. Again the sensor was replaced as a warranty repair item (they noted that the timing of the oxygen sensor going bad and the repair was suspicious).
I have been driving the car for about one week since the oxygen sensor was replaced and everything is back to normal.
My question to group is... Has anyone replaced their Oxygen Sensor more than once?
Cordially,
